drm: Allow also control clients to check the drm version

2015-09-24T07:24:24+00:00

This should be harmless. Vmware will, due to old infrastructure reasons, be using a privileged control client to supply GUI layout information rather than obtaining it from the device. That control client will be needing access to DRM version information. Signed-off-by: Thomas Hellstrom Reviewed-by: Brian Paul Reviewed-by: Sinclair Yeh Acked-by: David Herrmann

Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Pull drm updates from Dave Airlie: "This is the main drm pull request for v4.2. I've one other new driver from freescale on my radar, it's been posted and reviewed, I'd just like to get someone to give it a last look, so maybe I'll send it or maybe I'll leave it. There is no major nouveau changes in here, Ben was working on something big, and we agreed it was a bit late, there wasn't anything else he considered urgent to merge. There might be another msm pull for some bits that are waiting on arm-soc, I'll see how we time it. This touches some "of" stuff, acks are in place except for the fixes to the build in various configs,t hat I just applied. Summary: New drivers: - virtio-gpu: KMS only pieces of driver for virtio-gpu in qemu. This is just the first part of this driver, enough to run unaccelerated userspace on. As qemu merges more we'll start adding the 3D features for the virgl 3d work. - amdgpu: a new driver from AMD to driver their newer GPUs. (VI+) It contains a new cleaner userspace API, and is a clean break from radeon moving forward, that AMD are going to concentrate on. It also contains a set of register headers auto generated from AMD internal database. core: - atomic modesetting API completed, enabled by default now. - Add support for mode_id blob to atomic ioctl to complete interface. - bunch of Displayport MST fixes - lots of misc fixes. panel: - new simple panels - fix some long-standing build issues with bridge drivers radeon: - VCE1 support - add a GPU reset counter for userspace - lots of fixes. amdkfd: - H/W debugger support module - static user-mode queues - support killing all the waves when a process terminates - use standard DECLARE_BITMAP i915: - Add Broxton support - S3, rotation support for Skylake - RPS booting tuning - CPT modeset sequence fixes - ns2501 dither support - enable cmd parser on haswell - cdclk handling fixes - gen8 dynamic pte allocation - lots of atomic conversion work exynos: - Add atomic modesetting support - Add iommu support - Consolidate drm driver initialization - and MIC, DECON and MIPI-DSI support for exynos5433 omapdrm: - atomic modesetting support (fixes lots of things in rewrite) tegra: - DP aux transaction fixes - iommu support fix msm: - adreno a306 support - various dsi bits - various 64-bit fixes - NV12MT support rcar-du: - atomic and misc fixes sti: - fix HDMI timing complaince tilcdc: - use drm component API to access tda998x driver - fix module unloading qxl: - stability fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (872 commits) drm/nouveau: Pause between setting gpu to D3hot and cutting the power drm/dp/mst: close deadlock in connector destruction. drm: Always enable atomic API drm/vgem: Set unique to "vgem" of: fix a build error to of_graph_get_endpoint_by_regs function drm/dp/mst: take lock around looking up the branch device on hpd irq drm/dp/mst: make sure mst_primary mstb is valid in work function of: add EXPORT_SYMBOL for of_graph_get_endpoint_by_regs ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi' drm/atomic: Don't set crtc_state->enable manually drm/exynos: dsi: do not set TE GPIO direction by input drm/exynos: dsi: add support for MIC driver as a bridge drm/exynos: dsi: add support for Exynos5433 drm/exynos: dsi: make use of array for clock access drm/exynos: dsi: make use of driver data for static values drm/exynos: dsi: add macros for register access drm/exynos: dsi: rename pll_clk to sclk_clk drm/exynos: mic: add MIC driver of: add helper for getting endpoint node of specific identifiers drm/exynos: add Exynos5433 decon driver ...

drm: Always enable atomic API

2015-06-24T01:21:35+00:00

Now that the interface has been proven by a port of Weston (using all atomic features including TEST_ONLY), remove the module parameter guarding the atomic API from being exposed, and let it run free in the wild. Signed-off-by: Daniel Stone Acked-by: Daniel Vetter Signed-off-by: Dave Airlie

x86/mm/mtrr: Avoid #ifdeffery with phys_wc_to_mtrr_index()

2015-05-27T12:41:00+00:00

There is only one user but since we're going to bury MTRR next out of access to drivers, expose this last piece of API to drivers in a general fashion only needing io.h for access to helpers.

drm/mode: Add user blob-creation ioctl

2015-05-22T14:18:28+00:00

Add an ioctl which allows users to create blob properties from supplied data. Currently this only supports modes, creating a drm_display_mode from the userspace drm_mode_modeinfo. v2: Removed size/type checks. Rebased on new patches to allow error propagation from create_blob, as well as avoiding double-allocation.

drm: Simplify core vs. drv ioctl handling

2015-03-27T15:08:41+00:00

Now that cmd_drv is gone the handling for core and driver ioctls is mostly identical, so eliminate the duplication. Also take the opportunity to simplify the range checks to be less cluttered. Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter
