2014-08-10drm/nouveau/core: import ioctl/event interfacesBen Skeggs13-4/+831
This forms the basis for the new APIs that will be exposed to userspace, giving it access to: - Object method calls, the immediately useful of which is performance counters and the abiity to manipulate the ZBC tables. - Information on the child classes an object supports, in order to avoid having to try all supported classes until successful. - Notifications, which will be used in the future to inform the client if its channel was killed due to a lockup, etc. This commit imports the interfaces, but are not currently used. The DRM portion of the driver will be ported to speak to the core using these interfaces as much as possible. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-08-10drm/nouveau/core: rework event interfaceBen Skeggs52-517/+875
This is a lot of prep-work for being able to send event notifications back to userspace. Events now contain data, rather than a "something just happened" signal. Handler data is now embedded into a containing structure, rather than being kmalloc()'d, and can optionally have the notify routine handled in a workqueue. Various races between suspend/unload with display HPD/DP IRQ handlers automagically solved as a result. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-08-10drm/nouveau: Bump version from 1.1.1 to 1.1.2Mario Kleiner1-1/+3
Linux 3.16 fixed multiple bugs in kms pageflip completion events and timestamping, which were originally introduced in Linux 3.13. These fixes have been backported to all stable kernels since 3.13. However, the userspace nouveau-ddx needs to be aware if it is running on a kernel on which these bugs are fixed, or not. Bump the patchlevel of the drm driver version to signal this, so backporting this patch to stable 3.13+ kernels will give the ddx the required info.

2014-08-10drm/nouveau: Dis/Enable vblank irqs during suspend/resume.Mario Kleiner1-0/+11
Vblank irqs don't get disabled during suspend or driver unload, which causes irq delivery after "suspend" or driver unload, at least until the gpu is powered off. This could race with drm_vblank_cleanup() in the case of nouveau and cause a use-after-free bug if the driver is unloaded. More annoyingly during everyday use, at least on nv50 display engine (likely also others), vblank irqs are off after a resume from suspend, but the drm doesn't know this, so all vblank related functionality is dead after a resume. E.g., all windowed OpenGL clients will hang at swapbuffers time, as well as many fullscreen clients in many cases. This makes suspend/resume useless if one wants to use any OpenGL apps after the resume. In Linux 3.16, drm_vblank_on() was added, complementing the older drm_vblank_off() to solve these problems elegantly, so use those calls in nouveaus suspend/resume code. For kernels 3.8 - 3.15, we need to cherry-pick the drm_vblank_on() patch to support this patch.

2014-08-10drm/nouveau/clk: support for non-BIOS pstatesAlexandre Courbot9-20/+30
Make nouveau_clock_create() take new two optional arguments: an array of pstates and its size. When these are specified, nouveau_clock_create() will use the provided pstates instead of probing them using the BIOS. This is useful for platforms which do not provide a BIOS, like Tegra.

2014-08-10drm/nouveau: support for probing platform devicesAlexandre Courbot6-16/+291
Add a platform driver for Nouveau devices declared using the device tree or platform data. This driver currently supports GK20A on Tegra platforms and is only compiled for these platforms if Nouveau is enabled. Nouveau will probe the chip type itself using the BOOT0 register, so all this driver really needs to do is to make sure the module is powered and its clocks active before calling nouveau_drm_platform_probe().

2014-08-10drm/gk104/pwr: implement PGOB disable methodBen Skeggs6-3/+86
As documented at: ftp://download.nvidia.com/open-gpu-doc/gk104-disable-graphics-power-gating/1/gk104-disable-graphics-power-gating.txt NVIDIA were not able document the steps necessary to detect whether this is required or not at this time. However, they did confirm that this procedure is safe to perform unconditionally on GK104/6. GK107 does not have the power gating feature, and it was recommended that we do not perform these steps there as the effects were not verified. The disable path is from observing the binary driver, and not documented in the link above. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-08-08Revert "drm: drop redundant drm_file->is_master"Dave Airlie9-27/+20
This reverts commit 48ba813701eb14b3008edefef4a0789b328e278c. Thanks to Chris: "drm_file->is_master is not synomous with having drm_file->master == drm_file->minor->master. This is because drm_file->master is the same for all drm_files of the same generation and so when there is a master, every drm_file believes itself to be the master. Confusion ensues and things go pear shaped when one file is closed and there is no master anymore." Conflicts: drivers/gpu/drm/drm_drv.c drivers/gpu/drm/drm_stub.c

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v3.17-rc1 Mostly some cleanup all over the place. Pitch alignment limitations of the display controller are now honored and job submission is 64-bit safe. The SOR output (used for eDP) properly configures sync signal polarities according to the display mode rather than hard-coding them to some value and the number of bits per color is now taken from the panel rather than hard-coded to properly support 24-bit vs. 18-bit panels. The DSI controller now properly supports non-continuous clock mode. GEM objects can now have their flags and tiling mode modified via IOCTLs to allow buffers imported from Nouveau to be properly displayed. Newer generations of the Tegra display controller can also detile block linear buffers at scan-out time. Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it to be automatically loaded when built as a module. * tag 'drm/tegra/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: add MODULE_DEVICE_TABLEs drm/tegra: dc - Reset controller on driver remove drm/tegra: Properly align stride for framebuffers drm/tegra: sor - Configure proper sync polarities drm/tegra: sor - Use bits-per-color from panel drm/tegra: Make job submission 64-bit safe drm/tegra: Allow non-authenticated processes to create buffer objects drm/tegra: Add SET/GET_FLAGS IOCTLs drm/tegra: Add SET/GET_TILING IOCTLs drm/tegra: Implement more tiling modes drm/tegra: dsi - Handle non-continuous clock flag drm/tegra: sor - missing unlock on error

git://anongit.freedesktop.org/tegra/linux into drm-next drm/panel: Changes for v3.17-rc1 Panels can now be more finely controlled via .prepare() and .unprepare() callbacks in addition to .enable() and .disable(). New kerneldoc details what they are supposed to do and when they should be called. The simple panel driver gained support for a couple of new panels and it is now possible to specify additional delays during power up and power down sequences if panels require it. DSI devices can now advertise that they support non-continuous clock mode which will allow DSI host controllers to disable the high speed clock after transmissions to save power. * tag 'drm/panel/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux: (30 commits) drm/panel: simple: Use devm_gpiod_get_optional() drm/dsi: Replace upcasting macro by function drm/panel: ld9040: Replace upcasting macro by function drm/exynos: dp: Modify driver to support drm_panel drm/exynos: Move DP setup into commit() drm/panel: simple: Add AUO B133HTN01 panel support drm/panel: simple: Support delays in panel functions drm/panel: simple: Add proper definition for prepare and unprepare drm/panel: s6e8aa0: Add proper definition for prepare and unprepare drm/panel: ld9040: Add proper definition for prepare and unprepare drm/tegra: Add support for panel prepare and unprepare routines drm/exynos: dsi: Add support for panel prepare and unprepare routines drm/exynos: dpi: Add support for panel prepare and unprepare routines drm/panel: simple: Add dummy prepare and unprepare routines drm/panel: s6e8aa0: Add dummy prepare and unprepare routines drm/panel: ld9040: Add dummy prepare and unprepare routines drm/panel: Provide convenience wrapper for .get_modes() drm/panel: add .prepare() and .unprepare() functions drm/panel: simple: Remove simple-panel compatible drm/panel: simple: Add Innolux N116BGE panel support ...
