From 9674f35b1ec17577163897f052f405c1e9e5893d Mon Sep 17 00:00:00 2001 From: Cliff Wickman Date: Fri, 3 Apr 2009 08:34:05 -0500 Subject: x86: UV BAU and nodes with no memory This patch fixes BAU initialization for systems containing nodes with no memory and for systems with non-consecutive node numbers. Fixes and clarifies situations where pnode should be used instead of node id. Tested on the UV hardware simulator.

(somehow, long ago that function got eviscerated) If any cpu in the destination node does not get interrupted by the message and post completion in a reasonable time the hardware should respond to the sender with an error. This function enables such timeouts. Tested on the UV hardware simulator.

This makes sure that there is no window when identity map'ed attribute may disagree with ioremap range on the attribute type. This also avoids doing cpa on the ioremap'ed address twice (first in ioremap_page_range and then in ioremap_change_attr using vaddr), and should improve ioremap performance a bit.

That is if one CPU is changing the identity map memtype to _WC, no other CPU at the time of this change should not have a TLB for this page that carries a WB attribute. SDM suggests to make the page not present. But for that we will have to handle any page faults that can potentially happen due to these pages being not present. Other way to deal with this without having any WB mapping is to change the page first to UC and then to WC. This ensures that we meet the SDM requirement of no cacheable alais to WC page. This also has same or lower overhead than marking the page not present and making it present later.

For such PHY configurations using shared PHY interrupt phy_interrupt() handler will also schedule a work for PHY port which didn't cause an interrupt. This patch adds a possibility for PHY drivers to provide did_interrupt() function which reports if the PHY (or a PHY port in a multi-PHY device) generated an interrupt. This function is called in phy_change() as phy_change() shouldn't proceed if it is invoked for a PHY which didn't cause an interrupt.

McKenney" Date: Mon, 13 Apr 2009 21:31:16 -0700 Subject: rcu: Make hierarchical RCU less IPI-happy This patch fixes a hierarchical-RCU performance bug located by Anton Blanchard. The problem stems from a misguided attempt to provide a work-around for jiffies-counter failure. This work-around uses a per-CPU n_rcu_pending counter, which is incremented on each call to rcu_pending(), which in turn is called from each scheduling-clock interrupt. Each CPU then treats this counter as a surrogate for the jiffies counter, so that if the jiffies counter fails to advance, the per-CPU n_rcu_pending counter will cause RCU to invoke force_quiescent_state(), which in turn will (among other things) send resched IPIs to CPUs that have thus far failed to pass through an RCU quiescent state. Unfortunately, each CPU resets only its own counter after sending a batch of IPIs. This means that the other CPUs will also (needlessly) send -another- round of IPIs, for a full N-squared set of IPIs in the worst case every three scheduler-clock ticks until the grace period finally ends. It is not reasonable for a given CPU to reset each and every n_rcu_pending for all the other CPUs, so this patch instead simply disables the jiffies-counter "training wheels", thus eliminating the excessive IPIs. Note that the jiffies-counter IPIs do not have this problem due to the fact that the jiffies counter is global, so that the CPU sending the IPIs can easily reset things, thus preventing the other CPUs from sending redundant IPIs. Note also that the n_rcu_pending counter remains, as it will continue to be used for tracing.

The dasd driver can automatically online detected dasds, which especially important for finding the root device. Currently, it will wait for each online operation to finish individually, which may take long if many dasds need to be onlined. When using the new async framework, these onlining operations can run in parallel and presence of the root device is ensured by the fact that prepare_namespace() waits for all async threads to finish.

If the kernel paramert possible_cpus= is passed the cpu_possible_map is supposed to have x bits set. However the current code just sets the x bits without clearing the NR_CPUS bits that were already set. So we end up with an unchanged map that has all bits set. To fix this just clear the map before setting any new bits. This broke with def6cfb70bab83c0094bc0cedd27c4eda563043e "[S390] cpumask: Use accessors code."

The distribution bitmap had been constructed assuming 0 as the base node number. That construct would not have allowed a total system of greater than 256 nodes. It also corrects an error that occurred when the first blade's nasid was not zero. That nasid was stored as the base node. The base node number gets added by hardware to the node numbers implied in the distribution bitmap, resulting in invalid target nasids. Tested on the UV hardware simulator.

Fix it by moving the waking of the queue from skge_tx_clean() to the other caller. And to make sure start_xmit is not in progress on another CPU, skge_down() should call netif_tx_disable().

Alan Cox did the research, and just like the other radio protocols zero-length frames have meaning because at the top level ROSE is X.25 PLP. So this zero-length filtering is invalid.

With PREEMPT kernel ZAP_BLOCK_SIZE is 8 pages, so there is a noticeable performance penalty when unmapping a large VMA and the system is spending its time in flush_tlb_range(). The problem is that tlb_end_vma() is always flushing the full VMA range. The subrange that needs to be flushed can be calculated by tlb_remove_tlb_entry(). This approach was suggested by Hugh Dickins, and is also used by other arches. The speed increase is roughly 3x for 8M mappings and for larger mappings even more.

For some reason this wasn't actually the case until 3aa551c9b was merged but since this time, the ads7846 driver has deadlocked the system on first interrupt.

This adds a new call named block_write_full_page_endio so the buffer head end_io handler can be provided by the caller. This will be used by the ext3 data=guarded mode to do i_size updates in a workqueue based end_io handler. end_buffer_async_write is also exported so it can be called to do the dirty work of managing page writeback for the higher level end_io handler.

The "Broadcast Assist Unit" is used for TLB shootdown in UV. The memory mapped registers that point to sending and receiving memory structures contain node numbers. In one case the __pa() function did not provide the node id of memory on blade zero in configurations where that id is nonzero. In another case, it was assumed that memory was allocated on the local node. That assumption is not true in a configuration in which the node has no memory. Tested on the UV hardware simulator.

This reverts commit f520360d93cdc37de5d972dac4bf3bdef6a7f6a7. Tetsuo Handa, running a kernel with CONFIG_DEBUG_PAGEALLOC=y and CONFIG_UEVENT_HELPER_PATH=/sbin/hotplug, has been hitting RCU detected CPU stalls: it's been spinning in the loop where do_execve() counts up the args (but why wasn't fixup_exception working? dunno). The recent change, switching kobject_uevent_env() from UMH_WAIT_EXEC to UMH_NO_WAIT, is broken: the exec uses args on the local stack here, and an env which is kfreed as soon as call_usermodehelper() returns. It very much needs to wait for the exec to be done. An alternative would be to keep the UMH_NO_WAIT, and complicate the code to allocate and free these resources correctly? but no, as GregKH pointed out when making the commit, CONFIG_UEVENT_HELPER_PATH="" is a much better optimization - though some distros are still saying /sbin/hotplug in their .config, yet with no such binary in their initrd or their root.

Yes, a UMH_NO_WAIT or UMH_WAIT_PROC call_usermodehelper() spawns an mm-less kernel thread to do the exec. And in any case, that vm_enough_memory check when growing stack ought to be done on the target mm, not on the execer's mm (though apart from the warning, it only makes a slight tweak to OVERCOMMIT_NEVER behaviour).

This patch just removes the track/untrack of vm_insert_pfn. That means we will be in same state as 2.6.28, with respect to these APIs.

So as long as sysfs attributes cannot commit suicide directly and we are stuck with this callback mechanism, put the sysfs callbacks on their own workqueue instead of the global one. This has the side benefit that if a suicidal sysfs attribute kicks off a long chain of ->remove callbacks, we no longer induce a long delay on the global queue. This also fixes a missing module_put in the error path introduced by sysfs-only-allow-one-scheduled-removal-callback-per-kobj.patch. We never destroy the workqueue, but I'm not sure that's a problem.

Platform drivers are great for embedded platforms because we can separate driver configuration from the actual driver. So base addresses, interrupts and other configuration can be kept with the processor or board code, and the platform driver can be reused by many different platforms. For early devices we have nothing today. For instance, to configure early timers and early serial ports we cannot use platform devices. This because the setup order during boot. Timers are needed before the platform driver core code is available. The same goes for early printk support. Early in this case means before initcalls. These early drivers today have their configuration either hard coded or they receive it using some special configuration method. This is working quite well, but if we want to support both regular kernel modules and early devices then we need to have two ways of configuring the same driver. A single way would be better. The early platform driver patch is basically a set of functions that allow drivers to register themselves and architecture code to locate them and probe. Registration happens through early_param(). The time for the probe is decided by the architecture code. See Documentation/driver-model/platform.txt for more details.

This is now no longer the case in practice[1]. There are places where it's useful to have debugging printks, but we don't want them to generate any code in production kernels. So add a new macro, pr_devel(), for _devel_opment, to provide the old semantics, ie. if the programmer doesn't explicitly enable debugging, no code is produced. [1]: You can turn CONFIG_DYNAMIC_DEBUG off, but it's enabled in at least one distro kernel, so it's not really a solution.

There is an important issue with such transfers, especially on the host side: when such transfers end with a full-size packet, we must defer musb_dma_completion() calls until the FIFO empties. Else we report URB completions too soon, and may clobber data in the FIFO fifo when writing the next packet (losing data). The Inventra DMA support uses DMA mode 1, but it ignores that issue. The CPPI DMA support uses mode 0, but doesn't handle its TXPKTRDY interrupts quite right either; it can get stale "packet ready" interrupts, and report transfer completion too early using slightly different code paths, also losing data. So I'm solving it in a generic way -- by adding a sort of the "interrupt filter" into musb_host_tx(), catching these cases where a DMA completion IRQ doesn't suffice and removing some needlessly controller-specific logic. When a TXDMA interrupt happens and DMA request mode 1 is active, that filter resets to mode 0 and defers URB completion processing until TXPKTRDY, unless the FIFO is already empty. Related filtering logic in Inventra and CPPI code gets removed. Since it should be competely safe now to use the DMA request mode 1 for host side transfers with the CPPI DMA controller, set it in musb_h_tx_dma_start() ... now renamed (and shared).

With Inventra DMA they complete, but in PIO mode. To fix: - Factor out programming of the DMA transfer from musb_ep_program() into musb_tx_dma_program(); - Reorder the code at the end of musb_host_tx() to facilitate the fallback to PIO iff DMA fails; - Handle the buffer offset consistently for both PIO and DMA modes; - Add an argument to musb_ep_program() for the same reason (it only worked correctly with non-zero offset of the first frame in PIO mode); - Set the completed isochronous frame descriptor's 'actual_length' and 'status' fields correctly in DMA mode. Also, since CPPI reportedly doesn't like sending isochronous packets in the RNDIS mode, change the criterion for this mode to be used only for multi-packet transfers. (There's no need for that mode in the single-packet case anyway.)

Fixup of Werner Cornelius patch to the ch341 USB-serial driver, which adds: - support all baudrates, not just a hard-coded set - support for controlling DTR, RTS and CTS Features still missing: - character length other than 8 bits - parity settings - break control I adapted his patch for the new usb_serial API introduced in 2.6.25-git8 by Alan Cox on 22 July 2008. Non-compliance to the new API was a reason for refusing a similar patch from Tollef Fog Heen. Usage example by Tollef Fog Heen : TEMPer USB thermometer based on a patch by: From: Tollef Fog Heen * Implement support for all baud rates rather than just a hard coded set. * Make it possible to control status and control lines * Grab a bunch of #defines from FreeBSD to reduce the number of magic numbers in the file Signed-off-by: Werner Cornelius Signed-off-by: Boris Hajduk Cc: Alan Cox Signed-off-by: Tollef Fog Heen Signed-off-by: Greg Kroah-Hartman --- drivers/usb/serial/ch341.c | 374 ++++++++++++++++++++++++++++++++++++--------- 1 file changed, 302 insertions(+), 72 deletions(-) diff --git a/drivers/usb/serial/ch341.c b/drivers/usb/serial/ch341.c index d33d39d..ab4cc27 100644 --- a/drivers/usb/serial/ch341.c +++ b/drivers/usb/serial/ch341.c @@ -1,5 +1,7 @@ /* * Copyright 2007, Frank A Kingswood + * Copyright 2007, Werner Cornelius + * Copyright 2009, Boris Hajduk * * ch341.c implements a serial port driver for the Winchiphead CH341. * @@ -21,9 +23,39 @@ #include #include -#define DEFAULT_BAUD_RATE 2400 +#define DEFAULT_BAUD_RATE 9600 #define DEFAULT_TIMEOUT 1000 +/* flags for IO-Bits */ +#define CH341_BIT_RTS (1 << 6) +#define CH341_BIT_DTR (1 << 5) + +/******************************/ +/* interrupt pipe definitions */ +/******************************/ +/* always 4 interrupt bytes */ +/* first irq byte normally 0x08 */ +/* second irq byte base 0x7d + below */ +/* third irq byte base 0x94 + below */ +/* fourth irq byte normally 0xee */ + +/* second interrupt byte */ +#define CH341_MULT_STAT 0x04 /* multiple status since last interrupt event */ + +/* status returned in third interrupt answer byte, inverted in data + from irq */ +#define CH341_BIT_CTS 0x01 +#define CH341_BIT_DSR 0x02 +#define CH341_BIT_RI 0x04 +#define CH341_BIT_DCD 0x08 +#define CH341_BITS_MODEM_STAT 0x0f /* all bits */ + +/*******************************/ +/* baudrate calculation factor */ +/*******************************/ +#define CH341_BAUDBASE_FACTOR 1532620800 +#define CH341_BAUDBASE_DIVMAX 3 + static int debug; static struct usb_device_id id_table [] = { @@ -34,9 +66,12 @@ static struct usb_device_id id_table [] = { MODULE_DEVICE_TABLE(usb, id_table); struct ch341_private { - unsigned baud_rate; - u8 dtr; - u8 rts; + spinlock_t lock; /* access lock */ + wait_queue_head_t delta_msr_wait; /* wait queue for modem status */ + unsigned baud_rate; /* set baud rate */ + u8 line_control; /* set line control value RTS/DTR */ + u8 line_status; /* active status of modem control inputs */ + u8 multi_status_change; /* status changed multiple since last call */ }; static int ch341_control_out(struct usb_device *dev, u8 request, @@ -72,37 +107,28 @@ static int ch341_set_baudrate(struct usb_device *dev, { short a, b; int r; + unsigned long factor; + short divisor; dbg("ch341_set_baudrate(%d)", priv->baud_rate); - switch (priv->baud_rate) { - case 2400: - a = 0xd901; - b = 0x0038; - break; - case 4800: - a = 0x6402; - b = 0x001f; - break; - case 9600: - a = 0xb202; - b = 0x0013; - break; - case 19200: - a = 0xd902; - b = 0x000d; - break; - case 38400: - a = 0x6403; - b = 0x000a; - break; - case 115200: - a = 0xcc03; - b = 0x0008; - break; - default: + + if (!priv->baud_rate) return -EINVAL; + factor = (CH341_BAUDBASE_FACTOR / priv->baud_rate); + divisor = CH341_BAUDBASE_DIVMAX; + + while ((factor > 0xfff0) && divisor) { + factor >>= 3; + divisor--; } + if (factor > 0xfff0) + return -EINVAL; + + factor = 0x10000 - factor; + a = (factor & 0xff00) | divisor; + b = factor & 0xff; + r = ch341_control_out(dev, 0x9a, 0x1312, a); if (!r) r = ch341_control_out(dev, 0x9a, 0x0f2c, b); @@ -110,19 +136,18 @@ static int ch341_set_baudrate(struct usb_device *dev, return r; } -static int ch341_set_handshake(struct usb_device *dev, - struct ch341_private *priv) +static int ch341_set_handshake(struct usb_device *dev, u8 control) { - dbg("ch341_set_handshake(%d,%d)", priv->dtr, priv->rts); - return ch341_control_out(dev, 0xa4, - ~((priv->dtr?1<<5:0)|(priv->rts?1<<6:0)), 0); + dbg("ch341_set_handshake(0x%02x)", control); + return ch341_control_out(dev, 0xa4, ~control, 0); } -static int ch341_get_status(struct usb_device *dev) +static int ch341_get_status(struct usb_device *dev, struct ch341_private *priv) { char *buffer; int r; const unsigned size = 8; + unsigned long flags; dbg("ch341_get_status()"); @@ -134,10 +159,15 @@ static int ch341_get_status(struct usb_device *dev) if (r < 0) goto out; - /* Not having the datasheet for the CH341, we ignore the bytes returned - * from the device.

So allow HCDs to provide a endpoint_reset method and call this or clear the software toggles as required (after a clear halt, set configuration etc.). usb_settoggle() and friends are then HCD internal and are moved into core/hcd.h and all device drivers call usb_reset_endpoint() instead. If the device endpoint state has been reset (with a clear halt) but the host endpoint state has not then subsequent data transfers will not complete. The device will only work again after it is reset or disconnected.

This errata affects WRITE_MULTI* commands when the device multi_count produces a DRQ block size >= 4Kbytes. We work around it here by converting such operations into ordinary PIO_WRITEs instead. Note that this might result in a PIO FUA write unavoidably being converted into a non-FUA write. In practice, any system using FUA is also going to be using DMA rather than PIO, so this shouldn't affect anyone in the real world.
