From dd17c8f72993f9461e9c19250e3f155d6d99df22 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 29 Oct 2009 22:34:15 +0900 Subject: percpu: remove per_cpu__ prefix. Now that the return from alloc_percpu is compatible with the address of per-cpu vars, it makes sense to hand around the address of per-cpu variables. To make this sane, we remove the per_cpu__ prefix we used created to stop people accidentally using these vars directly. Now we have sparse, we can use that (next patch). tj: * Updated to convert stuff which were missed by or added after the original patch. * Kill per_cpu_var() macro.

These could get quite big if we have to support systems with thousands of cpus. The use of this_cpu_xx operations results in: 1. The size of kmem_cache for SMP configuration shrinks since we will only need 1 pointer instead of NR_CPUS. The same pointer can be used by all processors. Reduces cache footprint of the allocator. 2. We can dynamically size kmem_cache according to the actual nodes in the system meaning less memory overhead for configurations that may potentially support up to 1k NUMA nodes / 4k cpus. 3. We can remove the diddle widdle with allocating and releasing of kmem_cache_cpu structures when bringing up and shutting down cpus. The cpu alloc logic will do it all for us. Removes some portions of the cpu hotplug functionality. 4. Fastpath performance increases since per cpu pointer lookups and address calculations are avoided.

The cacheline that holds the per cpu array pointer now also holds these values. We can cut down the struct kmem_cache_cpu size to almost half. The get_freepointer() and set_freepointer() functions that used to be only intended for the slow path now are also useful for the hot path since access to the size field does not require accessing an additional cacheline anymore. This results in consistent use of functions for setting the freepointer of objects throughout SLUB. Also we initialize all possible kmem_cache_cpu structures when a slab is created. No need to initialize them when a processor or node comes online.

The current Linux TCP implementation limits the advertised TCP initial receive window to the one prescribed by slow start. For short lived TCP connections used for transaction type of traffic (i.e. http requests), bounding the advertised TCP initial receive window results in increased latency to complete the transaction. Support for setting initial congestion window is already supported using rtnetlink init_cwnd, but the feature is useless without the ability to set a larger TCP initial receive window. The rtnetlink init_rcvwnd allows increasing the TCP initial receive window, allowing TCP connection to advertise larger TCP receive window than the ones bounded by slow start.

This drastically reduces the size of struct zone for systems with large amounts of processors and allows placement of critical variables of struct zone in one cacheline even on very large systems. Another effect is that the pagesets of one processor are placed near one another. If multiple pagesets from different zones fit into one cacheline then additional cacheline fetches can be avoided on the hot paths when allocating memory from multiple zones. Bootstrap becomes simpler if we use the same scheme for UP, SMP, NUMA. #ifdefs are reduced and we can drop the zone_pcp macro. Hotplug handling is also simplified since cpu alloc can bring up and shut down cpu areas for a specific cpu as a whole. So there is no need to allocate or free individual pagesets. V7-V8: - Explain chicken egg dilemmna with percpu allocator. V4-V5: - Fix up cases where per_cpu_ptr is called before irq disable - Integrate the bootstrap logic that was separate before. tj: Build failure in pageset_cpuup_callback() due to missing ret variable fixed.

Tunable per device via proc "proxy_arp_pvlan": /proc/sys/net/ipv4/conf/*/proxy_arp_pvlan This switch technology is known by different vendor names: - In RFC 3069 it is called VLAN Aggregation. - Cisco and Allied Telesyn call it Private VLAN. - Hewlett-Packard call it Source-Port filtering or port-isolation. - Ericsson call it MAC-Forced Forwarding (RFC Draft).

This allows user space applications to get access to IEs from Beacon frames even if we have received Probe Response frames from the BSS. Previously, the IEs from Probe Response frames would have overridden the IEs from Beacon frames. This feature is of somewhat limited use since most protocols include the same (or extended) information in Probe Response frames. However, there are couple of exceptions where the IEs from Beacon frames could be of some use: TIM IE is only included in Beacon frames (and it would be needed to figure out the DTIM period used in the BSS) and at least some implementations of Wireless Provisioning Services seem to include the full IE only in Beacon frames). The new BSS attribute for scan results is added to allow both the IE sets to be delivered. This is done in a way that maintains the previously used behavior for applications that are not aware of the new NL80211_BSS_BEACON_IES attribute.

Driver needs to use IEEE80211_HW_UAPSD to enable the feature.

Regular read/write behaviour is unchanged.

Tsirkin" Date: Thu, 14 Jan 2010 06:17:27 +0000 Subject: vhost_net: a kernel-level virtio server What it is: vhost net is a character device that can be used to reduce the number of system calls involved in virtio networking. Existing virtio net code is used in the guest without modification. There's similarity with vringfd, with some differences and reduced scope - uses eventfd for signalling - structures can be moved around in memory at any time (good for migration, bug work-arounds in userspace) - write logging is supported (good for migration) - support memory table and not just an offset (needed for kvm) common virtio related code has been put in a separate file vhost.c and can be made into a separate module if/when more backends appear. I used Rusty's lguest.c as the source for developing this part : this supplied me with witty comments I wouldn't be able to write myself. What it is not: vhost net is not a bus, and not a generic new system call. No assumptions are made on how guest performs hypercalls. Userspace hypervisors are supported as well as kvm. How it works: Basically, we connect virtio frontend (configured by userspace) to a backend. The backend could be a network device, or a tap device. Backend is also configured by userspace, including vlan/mac etc. Status: This works for me, and I haven't see any crashes. Compared to userspace, people reported improved latency (as I save up to 4 system calls per packet), as well as better bandwidth and CPU utilization. Features that I plan to look at in the future: - mergeable buffers - zero copy - scalability tuning: figure out the best threading model to use Note on RCU usage (this is also documented in vhost.h, near private_pointer which is the value protected by this variant of RCU): what is happening is that the rcu_dereference() is being used in a workqueue item. The role of rcu_read_lock() is taken on by the start of execution of the workqueue item, of rcu_read_unlock() by the end of execution of the workqueue item, and of synchronize_rcu() by flush_workqueue()/flush_work(). In the future we might need to apply some gcc attribute or sparse annotation to the function passed to INIT_WORK(). Paul's ack below is for this RCU usage.

There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely Acked-by: David S.

One such example is Mac mouse button emulation code which catches certain key presses and converts them into button clicks as if they were emitted by a virtual mouse. The original key press events should be completely suppressed, otherwise user space will be confused, and while keyboard driver does it on its own evdev is blissfully unaware of this arrangement. This patch adds notion of 'filter' to the standard input handlers, which may flag event as filtered thus preventing it from reaching other input handlers. Filters don't (nor will they ever) have a notion of priority relative to each other, input core will run all of them first and any one of them may mark event as filtered. This patch is inspired by similar patch by Matthew Garret but the implementation and intended usage are quite different.

This worked well enough until user space started using evdev which was completely unaware of this arrangement and kept sending original key presses to its users. Change the implementation to use newly added input filter framework so that original key presses are not transmitted to any handlers. As a bonus remove SYSCTL dependencies from the code and use Kconfig instead; also do not create the emulated mouse device until user activates emulation.

This has been fixed by 6bf8268f9a91f1 ("Bluetooth: Use the control channel for raw HID reports") Still, it is necessary to distinguish whether the report in question should be either FEATURE or OUTPUT. For this, we have to extend the generic HID API, so that hid_output_raw_report() callback provides means to specify this value so that it can be passed down to lower level hardware drivers (currently Bluetooth and USB).

Looking at the memory layout saved by "xsave", one can't say which state is represented in the memory layout. This is because if a particular state is in init state, in the xsave hdr it can be represented by bit '0'. And hence we can't really say by the xsave header wether a state is in init state or the state is not saved in the memory layout. And hence the xsave memory layout available through this regset interface uses SW usable bytes [464..511] to convey what state is represented in the memory layout. First 8 bytes of the sw_usable_bytes[464..467] will be set to OS enabled xstate mask(which is same as the 64bit mask returned by the xgetbv's xCR0). The note NT_X86_XSTATE represents the extended state information in the core file, using the above mentioned memory layout.

It is then responsible for rejecting ones that it decided not to handle. There is no unregistration, but the socket can be closed for that. Frames that are not registered for will not be forwarded to userspace and will be rejected by the kernel, the cfg80211 API helps implementing that. Additionally, this patch adds a new command that allows doing action frame transmission from userspace. It can be used either to exchange action frames on the current operational channel (e.g., with the AP with which we are currently associated) or to exchange off-channel Public Action frames with the remain-on-channel command.

This is so far attached to an application, which would require us to hold the corresponding lock across notification calls. But there is no direct relation between a controller up/down event and an application, so let's decouple them and provide a notifier call chain for those events instead. This notifier chain is first of all used internally. Here we request the highest priority to unsure that housekeeping work is done before any other notifications. The chain is exported via [un]register_capictr_notifier to our only user, capidrv, to replace the racy and unfixable capi20_set_callback. Signed-off-by: Jan Kiszka Signed-off-by: David S.

Add a simple command to make it possible to enable and disable power save via nl80211. I was also planning about extending the interface, for example adding the timeout value, but after thinking more about this I decided not to do it. Basically there were three reasons: Firstly, the parameters for power save are very much hardware dependent. Trying to find a unified interface which would work with all hardware, and still make sense to users, will be very difficult. Secondly, IEEE 802.11 power save implementation in Linux is still in state of flux. We have a long way to still to go and there is no way to predict what kind of implementation we will have after few years. And because we need to support nl80211 interface a long time, practically forever, adding now parameters to nl80211 might create maintenance problems later on. Third issue are the users. Power save parameters are mostly used for debugging, so debugfs is better, more flexible, interface for this. For example, wpa_supplicant currently doesn't configure anything related to power save mode. It's better to strive that kernel can automatically optimise the power save parameters, like with help of pm qos network and other traffic parameters. Later on, when we have better understanding of power save, we can extend this command with more features, if there's a need for that. Signed-off-by: Kalle Valo Signed-off-by: John W.

This is not particularly nice and if someone overlooks the #ifdef CONFIG_PCI_QUIRKS, build errors are introduced. To clean that up, move the definitions of the global variables in quirks.c that are always built to pci.c, move the definitions of the empty functions (compiled when CONFIG_PCI_QUIRKS is unset) to headers (additionally make these functions static inline) and modify drivers/pci/Makefile so that quirks.c is only built if CONFIG_PCI_QUIRKS is set.

Wysocki" Date: Wed, 17 Feb 2010 23:39:08 +0100 Subject: PCI PM: PCIe PME root port service driver PCIe native PME detection mechanism is based on interrupts generated by root ports or event collectors every time a PCIe device sends a PME message upstream. Once a PME message has been sent by an endpoint device and received by its root port (or event collector in the case of root complex integrated endpoints), the Requester ID from the message header is registered in the root port's Root Status register. At the same time, the PME Status bit of the Root Status register is set to indicate that there's a PME to handle. If PCIe PME interrupt is enabled for the root port, it generates an interrupt once the PME Status has been set. After receiving the interrupt, the kernel can identify the PCIe device that generated the PME using the Requester ID from the root port's Root Status register. [For details, see PCI Express Base Specification, Rev. 2.0.] Implement a driver for the PCIe PME root port service working in accordance with the above description. Based on a patch from Shaohua Li .

Wysocki" Date: Wed, 17 Feb 2010 23:44:09 +0100 Subject: PCI / ACPI / PM: Platform support for PCI PME wake-up Although the majority of PCI devices can generate PMEs that in principle may be used to wake up devices suspended at run time, platform support is generally necessary to convert PMEs into wake-up events that can be delivered to the kernel. If ACPI is used for this purpose, PME signals generated by a PCI device will trigger the ACPI GPE associated with the device to generate an ACPI wake-up event that we can set up a handler for, provided that everything is configured correctly. Unfortunately, the subset of PCI devices that have GPEs associated with them is quite limited. The devices without dedicated GPEs have to rely on the GPEs associated with other devices (in the majority of cases their upstream bridges and, possibly, the root bridge) to generate ACPI wake-up events in response to PME signals from them. Add ACPI platform support for PCI PME wake-up: o Add a framework making is possible to use ACPI system notify handlers for run-time PM. o Add new PCI platform callback ->run_wake() to struct pci_platform_pm_ops allowing us to enable/disable the platform to generate wake-up events for given device. Implemet this callback for the ACPI platform. o Define ACPI wake-up handlers for PCI devices and PCI root buses and make the PCI-ACPI binding code register wake-up notifiers for all PCI devices present in the ACPI tables. o Add function pci_dev_run_wake() which can be used by PCI drivers to check if given device is capable of generating wake-up events at run time.

We've increased this size several times when the table overflowed. But there's no good limit on the number of resources because host bridges and subtractive decode bridges can forward any number of ranges to their secondary buses. This patch reduces the table to only PCI_BRIDGE_RESOURCE_NUM (4) entries, which corresponds to the number of windows a PCI-to-PCI (3) or CardBus (4) bridge can positively decode. Any additional resources, e.g., PCI host bridge windows or subtractively-decoded regions, are kept in a list. I'd prefer a single list rather than this split table/list approach, but that requires simultaneous changes to every architecture. This approach only requires immediate changes where we set up (a) host bridges with more than four windows and (b) subtractive-decode P2P bridges, and we can incrementally change other architectures to use the list.

This eliminates the need for direct use of the security_ops and default_security_ops variables outside of security.c, so make security_ops and default_security_ops static. Also remove the secondary_ops variable as a cleanup since there is no use for that. secondary_ops was originally used by SELinux to call the "secondary" security module (capability or dummy), but that was replaced by direct calls to capability and the only remaining use is to save and restore the original security ops pointer value if SELinux is disabled by early userspace based on /etc/selinux/config. Further, if we support this directly in the security framework, then we can just use &default_security_ops for this purpose since that is now available.

The current method employs a daemon running in each guest that communicates memory statistics to a host daemon at a specified time interval. The host daemon aggregates this information and inflates and/or deflates balloons according to the level of host memory pressure. This approach is effective but overly complex since a daemon must be installed inside each guest and coordinated to communicate with the host. A simpler approach is to collect memory statistics in the virtio balloon driver and communicate them directly to the hypervisor. This patch enables the guest-side support by adding stats collection and reporting to the virtio balloon driver.

If the host supports this feature as well, the config space has the number of ports defined for that device. New ports are spawned according to this information. The config space also has the maximum number of ports that can be spawned for a particular device. This is useful in initializing the appropriate number of virtqueues in advance, as ports might be hot-plugged in later. Using this feature, generic ports can be created which are not tied to hvc consoles. We also open up a private channel between the host and the guest via which some "control" messages are exchanged for the ports, like whether the port being spawned is a console port, resizing the console window, etc. Next commits will add support for hotplugging and presenting char devices in /dev/ for bi-directional guest-host communication.

The rest of the devices use an in-RAM MCFG space for the purposes of device enumeration and initialization. There are a few uglies in the fake support, like BAR sizes that aren't a power of two, sizing detection, and writes to the real devices, but other than that it's pretty straightforward. Another way to think of this is not really as PCI at all, but just a table in RAM describing which devices are present, their capabilities and their offsets in MMIO space. This could have been done with a special new firmware table on this platform, but given that we do have some real PCI devices too, simply describing things in an MCFG type space was pretty simple.

The format of the local time return value matches that of clock_gettime (seconds and nanoseconds, instead of a single microseconds value from the existing ioctl).

McKenney" Date: Mon, 22 Feb 2010 17:04:45 -0800 Subject: rcu: Introduce lockdep-based checking to RCU read-side primitives Inspection is proving insufficient to catch all RCU misuses, which is understandable given that rcu_dereference() might be protected by any of four different flavors of RCU (RCU, RCU-bh, RCU-sched, and SRCU), and might also/instead be protected by any of a number of locking primitives. It is therefore time to enlist the aid of lockdep. This set of patches is inspired by earlier work by Peter Zijlstra and Thomas Gleixner, and takes the following approach: o Set up separate lockdep classes for RCU, RCU-bh, and RCU-sched. o Set up separate lockdep classes for each instance of SRCU. o Create primitives that check for being in an RCU read-side critical section. These return exact answers if lockdep is fully enabled, but if unsure, report being in an RCU read-side critical section. (We want to avoid false positives!) The primitives are: For RCU: rcu_read_lock_held(void) For RCU-bh: rcu_read_lock_bh_held(void) For RCU-sched: rcu_read_lock_sched_held(void) For SRCU: srcu_read_lock_held(struct srcu_struct *sp) o Add rcu_dereference_check(), which takes a second argument in which one places a boolean expression based on the above primitives and/or lockdep_is_held(). o A new kernel configuration parameter, CONFIG_PROVE_RCU, enables rcu_dereference_check(). This depends on CONFIG_PROVE_LOCKING, and should be quite helpful during the transition period while CONFIG_PROVE_RCU-unaware patches are in flight. The existing rcu_dereference() primitive does no checking, but upcoming patches will change that. Signed-off-by: Paul E.

McKenney" Date: Mon, 22 Feb 2010 17:04:59 -0800 Subject: rcu: Accelerate grace period if last non-dynticked CPU Currently, rcu_needs_cpu() simply checks whether the current CPU has an outstanding RCU callback, which means that the last CPU to go into dyntick-idle mode might wait a few ticks for the relevant grace periods to complete. However, if all the other CPUs are in dyntick-idle mode, and if this CPU is in a quiescent state (which it is for RCU-bh and RCU-sched any time that we are considering going into dyntick-idle mode), then the grace period is instantly complete. This patch therefore repeatedly invokes the RCU grace-period machinery in order to force any needed grace periods to complete quickly. It does so a limited number of times in order to prevent starvation by an RCU callback function that might pass itself to call_rcu(). However, if any CPU other than the current one is not in dyntick-idle mode, fall back to simply checking (with fix to bug noted by Lai Jiangshan). Also, take advantage of last grace-period forcing, the opportunity to do so noted by Steve Rostedt. And apply simplified #ifdef condition suggested by Frederic Weisbecker. Signed-off-by: Paul E.

The default value is 32 bytes, so if some structures are defined with a 4-byte alignment and others aren't declared with an alignment constraint at all - it will align at 32-bytes. For things like the ftrace events, this results in a non-standard array. When initializing the ftrace subsystem, we traverse the _ftrace_events section and call the initialization callback for each event. When the structures are misaligned, we could be treating another part of the structure (or the zeroed out space between them) as a function pointer. This patch forces the alignment for all the ftrace_event_call structures to 4 bytes. Without this patch, the kernel fails to boot very early when built with gcc 4.5. It's trivial to check the alignment of the members of the array, so it might be worthwhile to add something to the build system to do that automatically. Unfortunately, that only covers this case. I've asked one of the gcc developers about adding a warning when this condition is seen.

Kprobes uses breakpoint instruction for interrupting execution flow, on some architectures, it can be replaced by a jump instruction and interruption emulation code. This gains kprobs' performance drastically. To enable this feature, set CONFIG_OPTPROBES=y (default y if the arch supports OPTPROBE). Changes in v9: - Fix a bug to optimize probe when enabling. - Check nearby probes can be optimize/unoptimize when disarming/arming kprobes, instead of registering/unregistering. This will help kprobe-tracer because most of probes on it are usually disabled. Changes in v6: - Cleanup coding style for readability. - Add comments around get/put_online_cpus(). Changes in v5: - Use get_online_cpus()/put_online_cpus() for avoiding text_mutex deadlock.

Wysocki" Date: Sat, 23 Jan 2010 22:23:32 +0100 Subject: PM: Asynchronous suspend and resume of devices Theoretically, the total time of system sleep transitions (suspend to RAM, hibernation) can be reduced by running suspend and resume callbacks of device drivers in parallel with each other. However, there are dependencies between devices such that we're not allowed to suspend the parent of a device before suspending the device itself. Analogously, we're not allowed to resume a device before resuming its parent. The most straightforward way to take these dependencies into accout is to start the async threads used for suspending and resuming devices at the core level, so that async_schedule() is called for each suspend and resume callback supposed to be executed asynchronously. For this purpose, introduce a new device flag, power.async_suspend, used to mark the devices whose suspend and resume callbacks are to be executed asynchronously (ie. in parallel with the main suspend/resume thread and possibly in parallel with each other) and helper function device_enable_async_suspend() allowing one to set power.async_suspend for given device (power.async_suspend is unset by default for all devices). For each device with the power.async_suspend flag set the PM core will use async_schedule() to execute its suspend and resume callbacks. The async threads started for different devices as a result of calling async_schedule() are synchronized with each other and with the main suspend/resume thread with the help of completions, in the following way: (1) There is a completion, power.completion, for each device object. (2) Each device's completion is reset before calling async_schedule() for the device or, in the case of devices with the power.async_suspend flags unset, before executing the device's suspend and resume callbacks. (3) During suspend, right before running the bus type, device type and device class suspend callbacks for the device, the PM core waits for the completions of all the device's children to be completed. (4) During resume, right before running the bus type, device type and device class resume callbacks for the device, the PM core waits for the completion of the device's parent to be completed. (5) The PM core completes power.completion for each device right after the bus type, device type and device class suspend (or resume) callbacks executed for the device have returned.

Wysocki" Date: Wed, 27 Jan 2010 23:47:38 +0100 Subject: PM: Allow device drivers to use dpm_wait() There are some dependencies between devices (in particular, between EHCI USB controllers and their OHCI/UHCI siblings) which are not reflected by the structure of the device tree. With synchronous suspend and resume these dependencies are taken into accout automatically, because the devices in question are always registered in the right order, but to meet these constraints with asynchronous suspend and resume the drivers of these devices will need to use dpm_wait() in their suspend/resume routines, so introduce a helper function allowing them to do that.

The main issue is that non-high-speed devices must not be resumed before the high-speed root hub, because it is the ehci_bus_resume() routine which takes care of handing the device connection over to the companion controller. If the device resume is attempted before the handover then the device won't be found and it will be treated as though it had disconnected. The patch adds a new field to the usb_bus structure; for each full/low-speed bus this field will contain a pointer to the companion high-speed bus (if one exists). It is used during normal device resume; if the hs_companion pointer isn't NULL then we wait for the root-hub device on the hs_companion bus. A secondary issue is that an EHCI controlller shouldn't be resumed before any of its companions. On some machines I have observed handovers failing if the companion controller is reinitialized after the handover. Thus, the EHCI resume routine must wait for the companion controllers to be resumed. The patch also fixes a small bug in usb_hcd_pci_probe(); an error path jumps to the wrong label, causing a memory leak.

This changes ordering of some operations, in particular: - netlink notifications are sent after all changes have been performed. As a side effect this surpresses one unnecessary netlink message when the IFF_UP and other flags are changed simultaneously. - The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked after all changes have been performed.

In such a case, the Feroceon corrupts adjacent memory, which showed up in my tests as a crash in the rx path of ath9k that only occured with CONFIG_XFRM set.

These GPUs are typically wired to the laptop panel and VGA ports via a multiplexer unit which is controlled via ACPI methods. 4 combinations of systems typically exist - with 2 ACPI methods. Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method ATI/ATI - some ASUS - use ATPX ACPI Method Intel/Nvidia - - use _DSM ACPI method Nvidia/Nvidia - - use _DSM ACPI method. TODO: This patch adds support for the ATPX method and initial bits for the _DSM methods that need to written by someone with access to the hardware. Add a proper non-debugfs interface - need to get some proper testing first. v2: add power up/down support for both devices on W500 puts i915/radeon into D3 and cuts power to radeon. v3: redo probing methods, no DMI list, drm devices call to register with switcheroo, it tries to find an ATPX method on any device and once there is two devices + ATPX it inits the switcher. v4: ATPX msg handling using buffers - should work on more machines v5: rearchitect after more mjg59 discussion - move ATPX handling to radeon driver. v6: add file headers + initial nouveau bits (to be filled out). v7: merge delayed switcher code. v8: avoid suspend/resume of gpu that is off v9: rearchitect - mjg59 is always right. - move all ATPX code to radeon, should allow simpler DSM also proper ATRM handling v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv v11: fix bug in resuming Intel for 2nd time. v12: start fixing up nvidia code blindly. v13: blindly guess at finishing nvidia code v14: remove radeon audio hacks - fix up intel resume more like upstream v15: clean up printks + remove unnecessary igd/dis pointers mount debugfs /sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected + 2 cards. DIS - immediate change to discrete IGD - immediate change to IGD DDIS - delayed change to discrete DIGD - delayed change to IGD ON - turn on not in use OFF - turn off not in use Tested on W500 (Intel/ATI) and T500 (Intel/ATI) Signed-off-by: Dave Airlie --- include/linux/fb.h | 2 ++ include/linux/vga_switcheroo.h | 58 ++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 60 insertions(+) create mode 100644 include/linux/vga_switcheroo.h (limited to 'include/linux') diff --git a/include/linux/fb.h b/include/linux/fb.h index 369767b..c10163b 100644 --- a/include/linux/fb.h +++ b/include/linux/fb.h @@ -543,6 +543,8 @@ struct fb_cursor_user { #define FB_EVENT_GET_REQ 0x0D /* Unbind from the console if possible */ #define FB_EVENT_FB_UNBIND 0x0E +/* CONSOLE-SPECIFIC: remap all consoles to new fb - for vga switcheroo */ +#define FB_EVENT_REMAP_ALL_CONSOLE 0x0F struct fb_event { struct fb_info *info; diff --git a/include/linux/vga_switcheroo.h b/include/linux/vga_switcheroo.h new file mode 100644 index 0000000..4b58ab1 --- /dev/null +++ b/include/linux/vga_switcheroo.h @@ -0,0 +1,58 @@ +/* + * Copyright (c) 2010 Red Hat Inc. + * Author : Dave Airlie + * + * Licensed under GPLv2 + * + * vga_switcheroo.h - Support for laptop with dual GPU using one set of outputs + */ + +#include +#include + +enum vga_switcheroo_state { + VGA_SWITCHEROO_OFF, + VGA_SWITCHEROO_ON, +}; + +enum vga_switcheroo_client_id { + VGA_SWITCHEROO_IGD, + VGA_SWITCHEROO_DIS, + VGA_SWITCHEROO_MAX_CLIENTS, +}; + +struct vga_switcheroo_handler { + int (*switchto)(enum vga_switcheroo_client_id id); + int (*power_state)(enum vga_switcheroo_client_id id, + enum vga_switcheroo_state state); + int (*init)(void); + int (*get_client_id)(struct pci_dev *pdev); +}; + + +#if defined(CONFIG_VGA_SWITCHEROO) +void vga_switcheroo_unregister_client(struct pci_dev *dev); +int vga_switcheroo_register_client(struct pci_dev *dev, + void (*set_gpu_state)(struct pci_dev *dev, enum vga_switcheroo_state), + bool (*can_switch)(struct pci_dev *dev)); + +void vga_switcheroo_client_fb_set(struct pci_dev *dev, + struct fb_info *info); + +int vga_switcheroo_register_handler(struct vga_switcheroo_handler *handler); +void vga_switcheroo_unregister_handler(void); + +int vga_switcheroo_process_delayed_switch(void); + +#else + +static inline void vga_switcheroo_unregister_client(struct pci_dev *dev) {} +static inline int vga_switcheroo_register_client(struct pci_dev *dev, + void (*set_gpu_state)(struct pci_dev *dev, enum vga_switcheroo_state), + bool (*can_switch)(struct pci_dev *dev)) { return 0; } +static inline void vga_switcheroo_client_fb_set(struct pci_dev *dev, struct fb_info *info) {} +static inline int vga_switcheroo_register_handler(struct vga_switcheroo_handler *handler) { return 0; } +static inline void vga_switcheroo_unregister_handler(void) {} +static inline int vga_switcheroo_process_delayed_switch(void) { return 0; } + +#endif -- cgit v1.1 From 8edb381d6705811b278527907a5ae2a9c4db8074 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 1 Mar 2010 21:50:01 +1100 Subject: vga_switcheroo: fix build on platforms with no ACPI radeon was always including the atpx code unnecessarily, also core switcheroo was including acpi headers.

Some controllers have non-standard mechanism to indicate IRQ pending so that this condition can be detected and worked around. This patch adds an optional operation ->sff_irq_check() which will be called for each port from the ata_sff_interrupt() if an unexpected interrupt is received. If the operation returns %true, ->sff_check_status() and ->sff_irq_clear() will be cleared for the port. Note that this doesn't mark the interrupt as handled so it won't prevent IRQ subsystem from killing the IRQ if this mechanism fails to clear the spurious IRQ. This patch also implements ->sff_irq_check() for ata_piix. Note that this adds slight overhead to shared IRQ operation as IRQs which are destined for other controllers will trigger extra register accesses to check whether IDE interrupt is pending but this solves rare screaming IRQ cases and for some curious reason also helps weird BIOS related glitch on Samsung n130 as reported in bko#14314. http://bugzilla.kernel.org/show_bug.cgi?id=14314 * piix_base_ops dropped as suggested by Sergei. * Spurious IRQ detection doesn't kick in anymore if polling qc is in progress.

The SMBus alert protocol allows several SMBus slave devices to share a single interrupt pin on the SMBus master, while still allowing the master to know which slave triggered the interrupt. This is based on preliminary work by David Brownell. The key difference between David's implementation and mine is that his was part of i2c-core, while mine is split into a separate, standalone module named i2c-smbus. The i2c-smbus module is meant to include support for all SMBus extensions to the I2C protocol in the future. The benefit of this approach is a zero cost for I2C bus segments which do not need SMBus alert support. Where David's implementation increased the size of struct i2c_adapter by 7% (40 bytes on i386), mine doesn't touch it. Where David's implementation added over 150 lines of code to i2c-core (+10%), mine doesn't touch it. The only change that touches all the users of the i2c subsystem is a new callback in struct i2c_driver (common to both implementations.) I seem to remember Trent was worried about the footprint of David'd implementation, hopefully mine addresses the issue.

If the X server eventually uses this new mode, debugging and crash recovery should become easier. This is because even when currently in the VT of a frozen X server it would still be possible to switch out by doing SysRq-r and then CTRL-, sshing in and doing chvt , or any other method of VT switching. The general concensus on #xorg-devel seems to be that it should be safe to use this with X now that we have KMS. This also moves the VT_ACKACQ define to a more appropriate place, for clarity's sake.

If a driver knows that its device can handle suspends and resumes correctly, it can enable autosuspend all by itself. This is equivalent to the user writing "auto" to the device's power/level attribute. The implementation differs slightly from what it used to be. Now autosuspend is disabled simply by doing usb_autoresume_device() (to increment the usage counter) and enabled by doing usb_autosuspend_device() (to decrement the usage counter). The set_level() attribute method is updated to use the new routines, and the USB Power-Management documentation is updated. The patch adds a usb_enable_autosuspend() call to the hub driver's probe routine, allowing the special-case code for hubs in quirks.c to be removed.

This involves numerous changes throughout usbcore, especially to hub.c and driver.c. Perhaps the most notable change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME instead of CONFIG_PM. Several fields in the usb_device and usb_interface structures are no longer needed. Some code which used to depend on CONFIG_USB_PM now depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header files). The only visible change in behavior should be that following a system sleep (resume from RAM or resume from hibernation), autosuspended USB devices will be resumed just like everything else.

In order to ensure that consumers do not rely on the regulator before it is enabled provide an enable_time() operation and have the core delay for that time before returning to the caller. This is implemented as a function since the ramp rate may be specified in voltage per unit time and therefore the time depend on the configuration. In future it would be desirable to allow the bulk operations to run the delays for multiple enables in parallel but this is not currently supported.

So make Q_XQUOTASYNC call into the writeback code directly and make the quota_sync method optional as XFS doesn't need in the sense expected by the rest of the quota code. GFS2 was using limited XFS-style quota and has a quota_sync method fitting neither the style used by vfs_quota_sync nor xfs_fs_quota_sync. I left it in for now as per discussion with Steve it expects to be called from the sync path this way.

Move it into vfs_quota_sync and add a wait parameter to ->quota_sync to tell if we need it or not. My audit of the GFS2 code says it's also not needed given the way GFS2 implements quotas, but I'd be happy if this can get a detailed review.

This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the initialization. For most metadata operations this is a straight forward move into the methods, but for truncate and open it's a bit more complicated. For truncate we currently only call vfs_dq_init for the sys_truncate case because open already takes care of it for ftruncate and open(O_TRUNC) - the new code causes an additional vfs_dq_init for those which is harmless. For open the initialization is moved from do_filp_open into the open method, which means it happens slightly earlier now, and only for regular files. The latter is fine because we don't need to initialize it for operations on special files, and we already do it as part of the namespace operations for directories. Add a dquot_file_open helper that filesystems that support generic quotas can use to fill in ->open.

This patch adds per-thread cache for mm_counter. RSS value will be counted into a struct in task_struct and synchronized with mm's one at events. Now, in this patch, the event is the number of calls to handle_mm_fault. Per-thread value is added to mm at each 64 calls. rough estimation with small benchmark on parallel thread (2threads) shows [before] 4.5 cache-miss/faults [after] 4.0 cache-miss/faults Anyway, the most contended object is mmap_sem if the number of threads grows.

POSIX_FADV_RANDOM used to set ra_pages=0, which leads to poor performance: a 16K read will be carried out in 4 _sync_ 1-page reads. In other places, ra_pages==0 means - it's ramfs/tmpfs/hugetlbfs/sysfs/configfs - some IO error happened where multi-page read IO won't help or should be avoided. POSIX_FADV_RANDOM actually want a different semantics: to disable the *heuristic* readahead algorithm, and to use a dumb one which faithfully submit read IO for whatever application requests. So introduce a flag FMODE_RANDOM for POSIX_FADV_RANDOM. Note that the random hint is not likely to help random reads performance noticeably. And it may be too permissive on huge request size (its IO size is not limited by read_ahead_kb). In Quentin's report (http://lkml.org/lkml/2009/12/24/145), the overall (NFS read) performance of the application increased by 313%!

Specifically, each anon_vma will be shared between the parent process and all its child processes. In a workload with 1000 child processes and a VMA with 1000 anonymous pages per process that get COWed, this leads to a system with a million anonymous pages in the same anon_vma, each of which is mapped in just one of the 1000 processes. However, the current rmap code needs to walk them all, leading to O(N) scanning complexity for each page. This can result in systems where one CPU is walking the page tables of 1000 processes in page_referenced_one, while all other CPUs are stuck on the anon_vma lock. This leads to catastrophic failure for a benchmark like AIM7, where the total number of processes can reach in the tens of thousands. Real workloads are still a factor 10 less process intensive than AIM7, but they are catching up. This patch changes the way anon_vmas and VMAs are linked, which allows us to associate multiple anon_vmas with a VMA. At fork time, each child process gets its own anon_vmas, in which its COWed pages will be instantiated. The parents' anon_vma is also linked to the VMA, because non-COWed pages could be present in any of the children. This reduces rmap scanning complexity to O(1) for the pages of the 1000 child processes, with O(N) complexity for at most 1/N pages in the system. This reduces the average scanning cost in heavily forking workloads from O(N) to 2. The only real complexity in this patch stems from the fact that linking a VMA to anon_vmas now involves memory allocations. This means vma_adjust can fail, if it needs to attach a VMA to anon_vma structures. This in turn means error handling needs to be added to the calling functions. A second source of complexity is that, because there can be multiple anon_vmas, the anon_vma linking in vma_adjust can no longer be done under "the" anon_vma lock. To prevent the rmap code from walking up an incomplete VMA, this patch introduces the VM_LOCK_RMAP VMA flag. This bit flag uses the same slot as the NOMMU VM_MAPPED_COPY, with an ifdef in mm.h to make sure it is impossible to compile a kernel that needs both symbolic values for the same bitflag. Some test results: Without the anon_vma changes, when AIM7 hits around 9.7k users (on a test box with 16GB RAM and not quite enough IO), the system ends up running >99% in system time, with every CPU on the same anon_vma lock in the pageout code. With these changes, AIM7 hits the cross-over point around 29.7k users. This happens with ~99% IO wait time, there never seems to be any spike in system time. The anon_vma lock contention appears to be resolved.

It is also impossible for the rmap code to follow a pointer to an already freed VMA, because the rmap code holds the anon_vma->lock, which the VMA teardown code needs to take before the VMA is removed from the anon_vma chain. Hence, we should not need the VM_LOCK_RMAP locking at all.

However, every mapped file page starts out like this and thus a problem arises when workloads create a stream of such pages that are used only for a short time. By flooding the active list with those pages, the VM quickly gets into trouble finding eligible reclaim canditates. The result is long allocation latencies and eviction of the wrong pages. This patch reuses the PG_referenced page flag (used for unmapped file pages) to implement a usage detection that scales with the speed of LRU list cycling (i.e. memory pressure). If the scanner encounters those pages, the flag is set and the page cycled again on the inactive list. Only if it returns with another page table reference it is activated. Otherwise it is reclaimed as 'not recently used cache'. This effectively changes the minimum lifetime of a used-once mapped file page from a full memory cycle to an inactive list cycle, which allows it to occur in linear streams without affecting the stable working set of the system.

This is used to implement wake-on-lan with SDIO wireless cards at the moment. Patches to add that support to the libertas driver will be posted separately. This patch: Some SDIO cards have the ability to keep on running autonomously when the host system is suspended, and wake it up when needed. This however requires that the host controller preserve power to the card, and configure itself appropriately for wake-up. There is however 4 layers of abstractions involved: the host controller driver, the MMC core code, the SDIO card management code, and the actual SDIO function driver. To make things simple and manageable, host drivers must advertise their PM capabilities with a feature bitmask, then function drivers can query and set those features from their suspend method. Then each layer in the suspend call chain is expected to act upon those bits accordingly.

This number is determined by the number of vmas which the process have. In particular, some extreme programs may use more than 65535 vmas. (If you google max_map_count, you can find some users facing this problem.) This kind of program never be able to generate correct coredumps. This patch implements ``extended numbering'' that uses sh_info field of the first section header instead of e_phnum field in order to represent upto 4294967295 vmas. This is supported by AMD64-ABI(http://www.x86-64.org/documentation.html) and Solaris(http://docs.sun.com/app/docs/doc/817-1984/). Of course, we are preparing patches for gdb and binutils.

Hardware designer can use them together or only one of them according to requirement. There's some logic tightly linked between these two chips. For example, USB charger driver needs to access both chips by I2C interface. Now share one driver to these two devices. Only one I2C client is identified in platform init data. If another chip is also used, user should mark it in companion_addr field of platform init data. Then driver could create another I2C client for the companion chip. All I2C operations are accessed by 860x-i2c driver. In order to support both I2C client address, the read/write API is changed in below. reg_read(client, offset) reg_write(client, offset, data) The benefit is that client drivers only need one kind of read/write API. I2C and MFD driver can be shared in both 8606 and 8607. Since API is changed, update API in 8607 regulator driver.

It works through the I2C bus and acts as a GPIO extender. Specifically: * it can have several sub-devices, each with its own I2C address * Each sub-device provides 8 output and 8 input pins * The chip attaches to one GPIO to signal when any of the input GPIOs change -- at which point all chips must be scanned for changes This driver implements the GPIOs throught the kernel's GPIO and IRQ framework. This allows any GPIO-servicing drivers to operate on htcpld pins, such as the gpio-keys and gpio-leds drivers.

ultra low power audio hub CODEC. Since it includes on-board regulators and GPIOs it is represented as a multi-function device, though the overwhelming majority of the functionality is provided by the ASoC CODEC driver.

While testing the I2C in High Speed mode, it was discovered that without a proper pull-up resistor, there is data corruption during multi-byte transfer. RTC(time_set) test case was used for testing. From the analysis done, it was concluded that ideally we need a pull-up of 1.6k Ohm(recomended) or atleast 470 Ohm or greater for assured performance in HS mode.

Acknowledge that the logical sysfs rwsem has one instance per sysfs attribute with different locking depencencies for different attributes. There is a sysfs idiom where writing to one sysfs file causes the addition or removal of other sysfs files. Lumping all of the sysfs attributes together in one lock class causes lockdep to generate lots of false positives. This introduces the requirement that non-static sysfs attributes need to be initialized with sysfs_attr_init or sysfs_bin_attr_init. Strictly speaking this requirement only exists when lockdep is enabled, and when lockdep is enabled we get a bit fat warning if this requirement is not met. Signed-off-by: Eric W.

Biederman" Date: Fri, 12 Feb 2010 04:35:32 -0800 Subject: sysfs: Document sysfs_attr_init and sysfs_bin_attr_init I have added a new requirement to the external sysfs interface that dynamically allocated sysfs attributes must call sysfs_attr_init if lockdep is enabled. For the time being callying sysfs_attr_init is only mandatory if lockdep is enabled, so we can live with a few unconverted instances until we find them all. As this is part of the public interface of sysfs it is a good idea to document these pseudo functions so someone inspeciting the code can find out what has happened. Signed-off-by: Eric W.

This patch creates the device_lock/unlock/trylock() functions, and converts all in-tree users to them.
