git://people.freedesktop.org/~danvet/drm-intel into drm-next Bit a bit -fixes pull request in the merge window than usual dua to two feauture-y things: - Display CRCs are now enabled on all platforms, including the odd DP case on gm45/vlv. Since this is a testing-only feature it should ever hurt, but I figured it'll help with regression-testing -fixes. So I left it in and didn't postpone it to 3.14. - Display power well refactoring from Imre. Would have caused major pain conflict with the bdw stage 1 patches if I'd postpone this to -next. It's only an relatively small interface rework, so shouldn't cause pain. It's also been in my tree since almost 3 weeks already. That accounts for about two thirds of the pull, otherwise just bugfixes: - vlv backlight fix from Jesse/Jani - vlv vblank timestamp fix from Jesse - improved edp detection through vbt from Ville (fixes a vlv issue) - eDP vdd fix from Paulo - fixes for dvo lvds on i830M - a few smaller things all over Note: This contains a backmerge of v3.12. Since the -internal branch always applied on top of -nightly I need that unified base to merge bdw patches. So you'll get a conflict with radeon connector props when pulling this (and nouveau/master will also conflict a bit when Ben doesn't rebase). The backmerge itself only had conflicts in drm/i915.

into drm-next drm/tegra: Changes for v3.13-rc1 The biggest part of the changes is the decoupling of the host1x and DRM drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra from whence it came. There is a lot of cleanup as well, and the drivers can now be properly unloaded and reloaded. HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen. gr2d support was extended to Tegra114 and the gr3d driver that has been in the works for quite some time finally made it in. All pieces to run an OpenGL driver on top of an upstream kernel are now available. Support for syncpoint bases was added by Arto Merilainen. This is useful for synchronizing between command streams from different engines such as gr2d and gr3d. Erik Faye-Lund and Wei Yongjun contributed various small fixes.

I want to merge in the new Broadwell support as a late hw enabling pull request. But since the internal branch was based upon our drm-intel-nightly integration branch I need to resolve all the oustanding conflicts in drm/i915 with a backmerge to make the 60+ patches apply properly.

2013-10-18drm: Pad drm_mode_get_connector to 64-bit boundaryChris Wilson
Pavel Roskin reported that DRM_IOCTL_MODE_GETCONNECTOR was overwritting the 4 bytes beyond the end of its structure with a 32-bit userspace running on a 64-bit kernel. This is due to the padding gcc inserts as the drm_mode_get_connector struct includes a u64 and its size is not a natural multiple of u64s. 64-bit kernel: sizeof(drm_mode_get_connector)=80, alignof=8 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 32-bit userspace: sizeof(drm_mode_get_connector)=76, alignof=4 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 Fortuituously we can insert explicit padding to the tail of our structures without breaking ABI.

2013-10-12DRM: Armada: Add Armada DRM driverRussell King
This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs.

This capability allows user space to control the delivery of modes with the 3D flags set. This is to not play games with current user space users not knowing anything about stereo 3D flags and that could try to set a mode with one or several of those bits set. So, the plan is to remove the stereo modes from the list of modes we give to DRM clients by default, and let them through if we are being told otherwise. stereo_allowed is bound to the drm_file structure to make it a per-client setting, not a global one. v2: Replace clearing 3D flags by discarding the stereo modes now that they are regular modes. v3: SET_CAP -> SET_CLIENT_CAP rename (Chris Wilson) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-09-19drm/i915: Add second slice l3 remappingBen Widawsky
Certain HSW SKUs have a second bank of L3. This L3 remapping has a separate register set, and interrupt from the first "slice". A slice is simply a term to define some subset of the GPU's l3 cache. This patch implements both the interrupt handler, and ability to communicate with userspace about this second slice. v2: Remove redundant check about non-existent slice. Change warning about interrupts of unknown slices to WARN_ON_ONCE Handle the case where we get 2 slice interrupts concurrently, and switch the tracking of interrupts to be non-destructive (all Ville) Don't enable/mask the second slice parity interrupt for ivb/vlv (even though all docs I can find claim it's rsvd) (Ville + Bryan) Keep BYT excluded from L3 parity v3: Fix the slice = ffs to be decremented by one (found by Ville). When I initially did my testing on the series, I was using 1-based slice counting, so this code was correct. Not sure why my simpler tests that I've been running since then didn't pick it up sooner.

Add initial support for a3xx 3d core. So far, with hardware that I've seen to date, we can have: + zero, one, or two z180 2d cores + a3xx or a2xx 3d core, which share a common CP (the firmware for the CP seems to implement some different PM4 packet types but the basics of cmdstream submission are the same) Which means that the eventual complete "class" hierarchy, once support for all past and present hw is in place, becomes: + msm_gpu + adreno_gpu + a3xx_gpu + a2xx_gpu + z180_gpu This commit splits out the parts that will eventually be common between a2xx/a3xx into adreno_gpu, and the parts that are even common to z180 into msm_gpu. Note that there is no cmdstream validation required. All memory access from the GPU is via IOMMU/MMU. So as long as you don't map silly things to the GPU, there isn't much damage that the GPU can do.

2013-08-22drm/i915: Use Write-Through cacheing for the display plane on IrisChris Wilson
Haswell GT3e has the unique feature of supporting Write-Through cacheing of objects within the eLLC/LLC. The purpose of this is to enable the display plane to remain coherent whilst objects lie resident in the eLLC/LLC - so that we, in theory, get the best of both worlds, perfect display and fast access. However, we still need to be careful as the CPU does not see the WT when accessing the cache. In particular, this means that we need to flush the cache lines after writing to an object through the CPU, and on transitioning from a cached state to WT. v2: Actually do the clflush on transition to WT, nagging by Ville. v3: Flush the CPU cache after writes into WT objects. v4: Rease onto LLC updates and report WT as "uncached" for get_cache_level_ioctl to remain symmetric with set_cache_level_ioctl.

2013-07-25drm/gem: convert to new unified vma managerDavid Herrmann
Use the new vma manager instead of the old hashtable. Also convert all drivers to use the new convenience helpers. This drops all the (map_list.hash.key << PAGE_SHIFT) non-sense.

2013-06-28drm: add hotspot support for cursors.Dave Airlie
So it looks like for virtual hw cursors on QXL we need to inform the "hw" device what the cursor hotspot parameters are. This makes sense if you think the host has to draw the cursor and interpret clicks from it. However the current modesetting interface doesn't support passing the hotspot information from userspace. This implements a new cursor ioctl, that takes the hotspot info as well, userspace can try calling the new interface and if it gets -ENOSYS it means its on an older kernel and can just fallback.

2013-04-30drm: Kill user_modes list and the associated ioctlsVille Syrjälä
There is no way to use modes added to the user_modes list. We never look at the contents of said list in the kernel, and the only operations userspace can do are attach and detach. So the only "benefit" of this interface is wasting kernel memory. Fortunately it seems no real user space application ever used these ioctls. So just kill them. Also remove the prototypes for the non-existing drm_mode_addmode_ioctl() and drm_mode_rmmode_ioctl() functions. v2: Use drm_noop instead of completely removing the ioctls Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2013-04-12drm: add new QXL driver. (v1.4)Dave Airlie
QXL is a paravirtual graphics device used by the Spice virtual desktop interface. The drivers uses GEM and TTM to manage memory, the qxl hw fencing however is quite different than normal TTM expects, we have to keep track of a number of non-linear fence ids per bo that we need to have released by the hardware. The releases are freed from a workqueue that wakes up and processes the release ring. releases are suballocated from a BO, there are 3 release categories, drawables, surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling. The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface ids. This requires a newer version of the QXL userspace driver, so shouldn't be enabled until that has been placed into your distro of choice. Authors: Dave Airlie, Alon Levy v1.1: fixup some issues in the ioctl interface with padding v1.2: add module device table v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq, don't try flush release ring (broken hw), fix -modesetting. v1.4: fbcon cpu usage reduction + suitable accel flags.

2013-01-17drm/i915: Allow userspace to hint that the relocations were knownDaniel Vetter
Userspace is able to hint to the kernel that its command stream and auxiliary state buffers already hold the correct presumed addresses and so the relocation process may be skipped if the kernel does not need to move any buffers in preparation for the execbuffer. Thus for the common case where the allotment of buffers is static between batches, we can avoid the overhead of individually checking the relocation entries. Note that this requires userspace to supply the domain tracking and requests for workarounds itself that would otherwise be computed based upon the relocation entries.
