This is effectively a revert of 4573388c92ee60b4ed72b8d95b73df861189988c. Forcing a display active when there is none causes problems with dpm on some SI boards which results in improperly initialized dpm state and boot failures on some boards. As for the bug commit 4573388c92ee tried to address, one can manually force the state to high for better performance when using the card as a headless compute node until a better fix is developed. bugs: https://bugs.freedesktop.org/show_bug.cgi?id=73788 https://bugs.freedesktop.org/show_bug.cgi?id=69395 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> cc: stable@vger.kernel.org

2014-01-28drm/i915: Fix the offset issue for the stolen GEM objectsAkash Goel
The 'offset' field of the 'scatterlist' structure was wrongly programmed with the offset value from the base of stolen area, whereas this field indicates the offset from where the interested data starts within the first PAGE pointed to by 'scattterlist' structure. As a result when a new GEM object allocated from stolen area is mapped to GTT, it could lead to an overwrite of GTT entries as the page count calculation will go wrong, refer the function 'sg_page_count'. v2: Modified the commit message.

2014-01-27drm/i915: Decouple GPU error reporting from ring initialisationChris Wilson
Currently we report through our error state only the rings that have been initialised (as detected by ring->obj). This check is done after the GPU reset and ring re-initialisation, which means that the software state may not be the same as when we captured the hardware error and we may not print out any of the vital information for debugging the hang. This (and the implied object leak) is a regression from commit 3d57e5bd1284f44e325f3a52d966259ed42f9e05 Author: Ben Widawsky <ben@bwidawsk.net> Date: Mon Oct 14 10:01:36 2013 -0700 drm/i915: Do a fuller init after reset Note that we are already starting to get bug reports with incomplete error states from 3.13, which also hampers debugging userspace driver issues. v2: Prevent a NULL dereference on 830gm/845g after a GPU reset where the scratch obj may be NULL.

2014-01-24Merge tag 'pm+acpi-3.14-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "As far as the number of commits goes, the top spot belongs to ACPI this time with cpufreq in the second position and a handful of PM core, PNP and cpuidle updates. They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier. That should allow us to use ACPI during the timekeeping initialization and possibly to simplify the EFI initialization too. From Chun-Yi Lee. - Clenups of the inclusions of ACPI headers in many places all over from Lv Zheng and Rashika Kheria (work in progress). - New helper for ACPI _DSM execution and rework of the code in drivers that uses _DSM to execute it via the new helper.

2014-01-24Revert "drm/i915: Mask reserved bits in display/sprite address registers"Daniel Vetter
This reverts commit 446f254566ea8911c9e19c7bc8a162fc0e53cf31. I've left the masking in the pageflip code since that seems to be some useful piece of preemptive robustness. Iirc I've merged this patch under the assumption that the BIOS leaves some random gunk in the lower bits and gets unhappy if we trample on them. We have quite a few case like this, so this made sense. Now I've just learned that there's actual hardware features bits in the low 12 bits, and the kernel needs to preserve them to allow a userspace blob to do its job. Given Dave Airlie's clear stance on userspace blob drivers I've quickly chatted with him and he doesn't seem too happy. So let's revert this. If there are indeed bits that we must preserve in this range then we can ressurrect this patch, but with proper documentation for those bits supplied. And we probably also need to think a bit about interactions with our driver.

Some of the things included in this branch are: * Atmel SAMA5 conversion to common clock * Reset framework conversion for tegra platforms - Some of this depends on tegra clock driver reworks that are shared with Mike Turquette's clk tree. * Tegra DMA refactoring, which are shared branches with the DMA tree. * Removal of some header files on exynos to prepare for multiplatform" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (169 commits) ARM: mvebu: move Armada 370/XP specific definitions to armada-370-xp.h ARM: mvebu: remove prototypes of non-existing functions from common.h ARM: mvebu: move ARMADA_XP_MAX_CPUS to armada-370-xp.h serial: sh-sci: Rework baud rate calculation serial: sh-sci: Compute overrun_bit without using baud rate algo serial: sh-sci: Remove unused GPIO request code serial: sh-sci: Move overrun_bit and error_mask fields out of pdata serial: sh-sci: Support resources passed through platform resources serial: sh-sci: Don't check IRQ in verify port operation serial: sh-sci: Set the UPF_FIXED_PORT flag serial: sh-sci: Remove duplicate interrupt check in verify port op serial: sh-sci: Simplify baud rate calculation algorithms serial: sh-sci: Remove baud rate calculation algorithm 5 serial: sh-sci: Sort headers alphabetically ARM: EXYNOS: Kill exynos_pm_late_initcall() ARM: EXYNOS: Consolidate selection of PM_GENERIC_DOMAINS for Exynos4 ARM: at91: switch Calao QIL-A9260 board to DT clk: at91: fix pmc_clk_ids data type attriubte PM / devfreq: use inclusion <mach/map.h> instead of <plat/map-s5p.h> ARM: EXYNOS: remove <mach/regs-clock.h> for exynos ...

2014-01-23drm/tegra: Obtain head number from DTThierry Reding
The head number of a given display controller is fixed in hardware and required to program outputs appropriately. Relying on the driver probe order to determine this number will not work, since that could yield a situation where the second head was probed first and would be assigned head number 0 instead of 1. By explicitly specifying the head number in the device tree, it is no longer necessary to rely on these assumptions. As a fallback, if the property isn't available, derive the head number from the display controller node's position in the device tree. That's somewhat more reliable than the previous default but not a proper solution. Tested-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-01-23drm/i915: VLV2 - Fix hotplug detect bitsTodd Previte
Add new definitions for hotplug live status bits for VLV2 since they're in reverse order from the gen4x ones. Changelog: - Restored gen4 bit definitions - Added new definitions for VLV2 - Added platform check for IS_VALLEYVIEW() in dp_detect to use the correct bit defintions - Replaced a lost trailing brace for the added switch() Signed-off-by: Todd Previte <tprevite@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=73951 [danvet: Switch to _VLV postfix instead of prefix and regroupg comments again so that the g4x warning is right next to those defines. Also add a _G4X suffix for those special ones. Also cc stable.] Cc: stable@vger.kernel.org Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
