2014-01-03Merge tag 'pm+acpi-3.13-rc7' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and PM fixes and new device IDs from Rafael Wysocki: "These commits, except for one, are regression fixes and the remaining one fixes a divide error leading to a kernel panic. The majority of the regressions fixed here were introduced during the 3.12 cycle, one of them is from this cycle and one is older. Specifics: - VGA switcheroo was broken for some users as a result of the ACPI-based PCI hotplug (ACPIPHP) changes in 3.12, because some previously ignored hotplug events started to be handled. The fix causes them to be ignored again. - There are two more issues related to cpufreq's suspend/resume handling changes from the 3.12 cycle addressed by Viresh Kumar's fixes. - intel_pstate triggers a divide error in a timer function if the P-state information it needs is missing during initialization. This leads to kernel panics on nested KVM clients and is fixed by failing the initialization cleanly in those cases. - PCI initalization code changes during the 3.9 cycle uncovered BIOS issues related to ACPI wakeup notifications (some BIOSes send them for devices that aren't supposed to support ACPI wakeup). Work around them by installing an ACPI wakeup notify handler for all PCI devices with ACPI support. - The Calxeda cpuilde driver's probe function is tagged as __init, which is incorrect and causes a section mismatch to occur during build. Fix from Andre Przywara removes the __init tag from there. - During the 3.12 cycle ACPIPHP started to print warnings about missing _ADR for devices that legitimately don't have it. Fix from Toshi Kani makes it only print the warnings where they make sense" * tag 'pm+acpi-3.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPIPHP / radeon / nouveau: Fix VGA switcheroo problem related to hotplug intel_pstate: Fail initialization if P-state information is missing ARM/cpuidle: remove __init tag from Calxeda cpuidle probe function PCI / ACPI: Install wakeup notify handlers for all PCI devs with ACPI cpufreq: preserve user_policy across suspend/resume cpufreq: Clean up after a failing light-weight initialization ACPI / PCI / hotplug: Avoid warning when _ADR not present

2013-12-31ACPIPHP / radeon / nouveau: Fix VGA switcheroo problem related to hotplugRafael J. Wysocki
The changes in the ACPI-based PCI hotplug (ACPIPHP) subsystem made during the 3.12 development cycle uncovered a problem with VGA switcheroo that on some systems, when the device-specific method (ATPX in the radeon case, _DSM in the nouveau case) is used to turn off the discrete graphics, the BIOS generates ACPI hotplug events for that device and those events cause ACPIPHP to attempt to remove the device from the system (they are events for a device that was present previously and is not present any more, so that's what should be done according to the spec). Then, the system stops functioning correctly. Since the hotplug events in question were simply silently ignored previously, the least intrusive way to address that problem is to make ACPIPHP ignore them again. For this purpose, introduce a new ACPI device flag, no_hotplug, and modify ACPIPHP to ignore hotplug events for PCI devices whose ACPI companions have that flag set. Next, make the radeon and nouveau switcheroo detection code set the no_hotplug flag for the discrete graphics' ACPI companion.

Dynamic power mangement works reliably now, so enable it by default. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-12-24drm/radeon: enable gfx cgcg on CIK APUsAlex Deucher
Enable coarse grained clockgating. This works properly now that smc is initialized earlier than the rlc and cp. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-12-24drm/radeon/pm: move pm handling into the asic specific codeAlex Deucher
We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks. This makes dpm more reliable and makes clockgating work properly on CIK parts and should help on SI parts as well. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/dpm: switch on new late_enable callbackAlex Deucher
Right now it's called right after enable, but after reworking the dpm init order, it will get called later to accomodate loading the smc early, but enabling thermal interrupts and block powergating later after the ring tests are complete. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/dpm: add late_enable for KB/KVAlex Deucher
Make sure interrupts are enabled before we enable thermal interrupts. Also, don't powergate uvd, etc. until after the ring tests. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-12-24drm/radeon/dpm: add a late enable callbackAlex Deucher
Certain features need to be enabled after ring tests (e.g., powergating, etc.). Add a function pointer to split out late enable features. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
