* | ACPI / PM: Hold acpi_scan_lock over system PM transitionsRafael J. Wysocki2013-08-211-15/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bad things happen if ACPI hotplug events are handled during system PM transitions, especially if devices are removed as a result. To prevent those bad things from happening, acquire acpi_scan_lock when a PM transition is started and release it when that transition is complete or has been aborted. This fixes resume lockup on my test-bed Acer Aspire S5 that happens when Thunderbolt devices are disconnected from the machine while suspended. Also fixes the analogous problem for Mika Westerberg on an Intel DZ77RE-75K board. Signed-off-by: Rafael J.

* | ACPI / PM: Split device wakeup management routinesRafael J. Wysocki2012-11-151-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two device wakeup management routines in device_pm.c and sleep.c, acpi_pm_device_run_wake() and acpi_pm_device_sleep_wake(), take a device pointer argument and use it to obtain the ACPI handle of the corresponding ACPI namespace node. That handle is then used to get the address of the struct acpi_device object corresponding to the struct device passed as the argument. Unfortunately, that last operation may be costly, because it involves taking the global ACPI namespace mutex, so it shouldn't be carried out too often. However, the callers of those routines usually call them in a row with acpi_pm_device_sleep_state() which also takes that mutex for the same reason, so it would be more efficient if they ran acpi_bus_get_device() themselves to obtain a pointer to the struct acpi_device object in question and then passed that pointer to the appropriate PM routines. To make that possible, split each of the PM routines mentioned above in two parts, one taking a struct acpi_device pointer argument and the other implementing the current interface for compatibility. Additionally, change acpi_pm_device_run_wake() to actually return an error code if there is an error while setting up runtime remote wakeup for the device. Signed-off-by: Rafael J.

|/ | | | | | | | | | | | | | | | | | | | Make ACPI power management routines and PCI power management routines depending on ACPI take device PM QoS flags into account when deciding what power state to put the device into. In particular, after this change acpi_pm_device_sleep_state() will not return ACPI_STATE_D3_COLD as the deepest available low-power state if PM_QOS_FLAG_NO_POWER_OFF is requested for the device and it will not require remote wakeup to work for the device in the returned low-power state if there is at least one PM QoS flags request for the device, but PM_QOS_FLAG_REMOTE_WAKEUP is not requested for it. Accordingly, acpi_pci_set_power_state() will refuse to put the device into D3cold if PM_QOS_FLAG_NO_POWER_OFF is requested for it. Signed-off-by: Rafael J.

In this patch, a parameter to specify lowest allowed state for acpi_pm_device_sleep_state is added. So that the caller can enforce the constraint via the parameter. This is needed by PCIe D3cold support, where the lowest power state allowed may be D3_HOT instead of default D3_COLD.

Linux dutifully implemented _GTS and _BFS. We discovered that it was rarely seen in systems in the field. Further, some of those systems had AML so bogus that it could never work -- proof that no other operating system supports _GTS and _BFS. So we made _GTS and _BFS optional via modparam, and disabled them by default. But we've had to complicate some code to keep this support in the kernel, as these methods are defined to be evaluated very close to sleep entry and exit. Indeed, no other AML is ever evaluated with interrupts off. We have submitted a proposal for _GTS and _BFS to be officially removed from the ACPI specification on the next revision. Here we remove it from Linux. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Ingo Molnar <mingo@kernel.org> Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

In other words, the state returned by _PRW is the deepest (lowest-power) system sleep state the device is capable of waking up the system from. Moreover, acpi_pm_device_sleep_state() also should check if the wakeup capability is supported through ACPI, because in principle it may be done via native PCIe PME, for example, in which case _SxW should not be evaluated.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the system is woken up by the ACPI fixed power button, currently there is no way of userspace becoming aware that the power button was pressed. OLPC would like to know this, so that we can respond appropriately. For example, if the system was woken up by a network packet, we know we can go back to sleep very quickly. But if the user explicitly woke the system with the power button, we're going to want to stay awake for a while. The wakeup count mechanism seems like a good fit for communicating this. Mark the fixed power button as wakeup-enabled, and increment its wakeup counter when the system is woken with the power button. (The wakeup counter is also incremented when the power button is pressed during system operation; this is already handled by an existing acpi-button codepath).

Peter Anvin: "This code reworks all the "trampoline"/"realmode" code (various bits that need to live in the first megabyte of memory, most but not all of which runs in real mode at some point) in the kernel into a single object. The main reason for doing this is that it eliminates the last place in the kernel where we needed pages to be mapped RWX. This code separates all that code into proper R/RW/RX pages." Fix up conflicts in arch/x86/kernel/Makefile (mca removed next to reboot code), and arch/x86/kernel/reboot.c (reboot code moved around in one branch, modified in this one), and arch/x86/tools/relocs.c (mostly same code came in earlier due to working around the ld bugs just before the 3.4 release). Also remove stale x86-relocs entry from scripts/.gitignore as per Peter Anvin. * commit '61f5446169046c217a5479517edac3a890c3bee7': (36 commits) x86, realmode: Move end signature into header.S x86, relocs: When printing an error, say relative or absolute x86, relocs: More relocations which may end up as absolute x86, relocs: Workaround for binutils 2.22.52.0.1 section bug xen-acpi-processor: Add missing #include <xen/xen.h> acpi, bgrd: Add missing <linux/io.h> to drivers/acpi/bgrt.c x86, realmode: Change EFER to a single u64 field x86, realmode: Move kernel/realmode.c to realmode/init.c x86, realmode: Move not-common bits out of trampoline_common.S x86, realmode: Mask out EFER.LMA when saving trampoline EFER x86, realmode: Fix no cache bits test in reboot_32.S x86, realmode: Make sure all generated files are listed in targets x86, realmode: build fix: remove duplicate build x86, realmode: read cr4 and EFER from kernel for 64-bit trampoline x86, realmode: fixes compilation issue in tboot.c x86, realmode: move relocs from scripts/ to arch/x86/tools x86, realmode: header for trampoline code x86, realmode: flattened rm hierachy x86, realmode: don't copy real_mode_header x86, realmode: fix 64-bit wakeup sequence ...

* ACPI: Convert wake_sleep_flags to a value instead of functionKonrad Rzeszutek Wilk2012-04-231-24/+28
| | | | | | | | | | | | | | | | | | | | With commit a2ef5c4fd44ce3922435139393b89f2cce47f576 "ACPI: Move module parameter gts and bfs to sleep.c" the wake_sleep_flags is required when calling acpi_enter_sleep_state, which means that if there are functions outside the sleep.c code they can't get the wake_sleep_flags values. This converts the function in to a exported value and converts the module config operands to a function. Acked-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enhanced the sleep/wake interfaces to optionally execute the _GTS method (Going To Sleep), and the _BFS method (Back From Sleep). Windows apparently does not execute these methods, and therefore these methods are often untested. It has been seen on some systems where the execution of these methods causes errors and also prevents the machine from entering S5. It is therefore suggested that host operating systems do not execute these methods by default. In the future, perhaps these methods can be optionally executed based on the age of the system and/or what is the newest version of Windows that the BIOS asks for via _OSI.
