Merge branch 'primary-plane' of git://people.freedesktop.org/~robclark/linux into drm-next

2014-04-02T02:09:09Z

Here's the latest iteration of the universal planes work, which I believe is finally ready for merging. Aside from the minor driver patches to use the new drm_for_each_legacy_plane() macro for plane loops, these should all have an r-b from Rob Clark now. Actual userspace-visibility is currently hidden behind a drm.universal_planes module parameter so that we can do some experimental testing of this before flipping it on universally. * 'primary-plane' of git://people.freedesktop.org/~robclark/linux: drm/doc: Update plane documentation and add plane helper library drm: Allow userspace to ask for universal plane list (v2) drm: Remove unused drm_crtc->fb drm: Replace crtc fb with primary plane fb (v3) drm/msm: Switch to universal plane API's drm: Add drm_crtc_init_with_planes() (v2) drm: Add plane type property (v2) drm: Add drm_universal_plane_init() drm: Add primary plane helpers (v3) drm: Make drm_crtc_check_viewport non-static drm/shmobile: Restrict plane loops to only operate on legacy planes drm/i915: Restrict plane loops to only operate on overlay planes (v2) drm/exynos: Restrict plane loops to only operate on overlay planes (v2) drm: Add support for multiple plane types (v2)

drm: Specify a bit more the DRM_CAP_CURSOR_{WIDTH, HEIGHT} caps

2014-04-02T00:29:01Z

Earlier this week, there was a bit of confusion about those new capabilities, to the point I think it's better to document the intention and API contract. The comment documents the current situation: - the radeon driver returns the only valid size for the hw - i915 returns the maximun cursor size - other drivers fall back to returning 64x64 The common contract is to return a valid cursor size.

drm: Allow userspace to ask for universal plane list (v2)

2014-04-02T00:18:29Z

Userspace clients which wish to receive all DRM planes (primary and cursor planes in addition to the traditional overlay planes) may set the DRM_CLIENT_CAP_UNIVERSAL_PLANES capability. v2: Hide behind drm.universal_planes module option [suggested by Daniel Vetter] Signed-off-by: Matt Roper Reviewed-by: Rob Clark

drm: add DRM_CAPs for cursor size

2014-02-18T18:41:01Z

Some hardware may not support standard 64x64 cursors. Add a drm cap to query the cursor size from the kernel. Some examples include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32). This allows things like device specific ddxes to remove asics specific logic and also allows xf86-video-modesetting to work properly with hw cursors on this hardware. Default to 64 if the driver doesn't specify a size. Signed-off-by: Alex Deucher Reviewed-by: Rob Clark

drm/bufs: remove handling of _DRM_GEM mappings

2013-12-18T01:08:42Z

Gone with the new gem vma offset manager from David. We can also ditch the uapi header definition from the enum since userspace never used this. It ended up in there purely for historical reasons (for reusing the old drm mmap code essentially), not because userspace ever needed it.

drm: Add a STEREO_3D capability to the SET_CLIENT_CAP ioctl

2013-10-01T05:45:27Z

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 Signed-off-by: Damien Lespiau Acked-by: Dave Airlie Signed-off-by: Daniel Vetter

drm: Add a SET_CLIENT_CAP ioctl

2013-10-01T05:45:26Z

This ioctl can be used to turn some knobs in a DRM driver. The client can ask the DRM core for an alternate view of the reality: it can be useful to be able to instruct the core that the DRM client can handle new functionnality that would otherwise break current ABI. v2: Rename to ioctl from SET_CAP to SET_CLIENT_CAP (Chris Wilson) Reviewed-by: Ville Syrjälä Signed-off-by: Damien Lespiau Acked-by: Dave Airlie Signed-off-by: Daniel Vetter

drm: Move the GET_CAP macros next to the corresponding ioctl structure

2013-10-01T05:45:25Z

It's a tiny bit more logical to find the different capabilities you can use with the GET_CAP ioctl next to the structure rather than putting them at the end of the file. v2: Tab align the litterals (David Herrmann) v3: Make it clearer that DRM_PRIME_CAP_EXPORT/IMPORT are flags of DRM_CAP_PRIME. v4: Rebase on top of latest bits (DRM_CAP_ASYNC_PAGE_FLIP was introduced) Reviewed-by: David Herrmann (for v2) Signed-off-by: Damien Lespiau Acked-by: Dave Airlie Signed-off-by: Daniel Vetter

drm/gem: convert to new unified vma manager

2013-07-25T10:47:06Z

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. Locking and access-management is exactly the same as before with an additional lock inside of the vma-manager, which strictly wouldn't be needed for gem. v2: - rebase on drm-next - init nodes via drm_vma_node_reset() in drm_gem.c v3: - fix tegra v4: - remove duplicate if (drm_vma_node_has_offset()) checks - inline now trivial drm_vma_node_offset_addr() calls v5: - skip node-reset on gem-init due to kzalloc() - do not allow mapping gem-objects with offsets (backwards compat) - remove unneccessary casts Cc: Inki Dae Cc: Rob Clark Cc: Dave Airlie Cc: Thierry Reding Signed-off-by: David Herrmann Acked-by: Patrik Jakobsson Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie
