2018-10-04drm/i915: Use the correct crtc when sanitizing plane mappingVille Syrjälä
When we decide that a plane is attached to the wrong pipe we try to turn off said plane. However we are passing around the crtc we think that the plane is supposed to be using rather than the crtc it is currently using. That doesn't work all that well because we may have to do vblank waits etc. and the other pipe might not even be enabled here. So let's pass the plane's current crtc to intel_plane_disable_noatomic() so that it can its job correctly. To do that semi-cleanly we also have to change the plane readout to record the plane's visibility into the bitmasks of the crtc where the plane is currently enabled rather than to the crtc we want to use for the plane. One caveat here is that our active_planes bitmask will get confused if both planes are enabled on the same pipe. Fortunately we can use plane_mask to reconstruct active_planes sufficiently since plane_mask still has the same meaning (is the plane visible?) during readout. We also have to do the same during the initial plane readout as the second plane could clear the active_planes bit the first plane had already set. v2: Rely on fixup_active_planes() to populate active_planes fully (Daniel) Add Daniel's proposed comment to better document why we do this Drop the redundant intel_set_plane_visible() call Cc: stable@vger.kernel.org # fcba862e8428 drm/i915: Have plane->get_hw_state() return the current pipe Cc: stable@vger.kernel.org Cc: Dennis <dennis.nezic@utoronto.ca> Cc: Daniel Vetter <daniel@ffwll.ch> Tested-by: Dennis <dennis.nezic@utoronto.ca> Tested-by: Peter Nowee <peter.nowee@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105637 Fixes: b1e01595a66d ("drm/i915: Redo plane sanitation during readout") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181003145017.4527-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2018-10-02drm/i915: Add plane alpha blending support, v2.Maarten Lankhorst
Add plane alpha blending support with the different blend modes. This has been tested on a icl to show the correct results, on earlier platforms small rounding errors cause issues. But this already happens case with fully transparant or fully opaque RGB8888 fb's. The recommended HW workaround is to disable alpha blending when the plane alpha is 0 (transparant, hide plane) or 0xff (opaque, disable blending). This is easy to implement on any platform, so just do that. The tests for userspace are also available, and pass on gen11. Changes since v1: - Change mistaken < 0xff0 to 0xff00. - Only set PLANE_KEYMSK_ALPHA_ENABLE when plane alpha < 0xff00, ignore blend mode. - Rework disabling FBC when per pixel alpha is used.

2018-09-25drm/i915: Check fb stride against plane max strideVille Syrjälä
commit 4e0b83a567e2 ("drm/i915: Extract per-platform plane->check() functions") removed the plane max stride check for sprite planes. I was going to add it back when introducing GTT remapping for the display, but after further thought it seems better to re-introduce it separately. So let's add the max stride check back. And let's do it in a nicer form than what we had before and do it for all plane types (easy now that we have the ->max_stride() plane vfunc). Only sprite planes really need this for now since primary planes are capable of scanning out the current max fb size we allow, and cursors have more stringent stride checks elsewhere.

2018-09-13drm/i915: Fix a potential integer overflow with framebuffers extending past ↵Ville Syrjälä
4 GiB If we have framebuffers that are >= 4GiB in size we will overflow the fb size check in intel_fill_fb_info(). Currently that is only possible with NV12 and CCS as offsets[1] may be anything between 0 and 0xffffffff. offsets[0] is currently required to be 0 so we can't hit the overflow with any single plane format (thanks to max fb size of 8kx8k and max stride of 32 KiB). In the future we may allow almost any framebuffer to exceed 4GiB in size so we really should fix the overflow. Not that the overflow is particularly dangerous. It's mostly just a sanity check against insane userspace. The display engine can't write to memory anyway so I suppose in the worst case we might anger the hw by attempting scanout past the end of the ggtt, or we might scan out some data that we're not supposed to see from other parts of the ggtt. Note that triggering this overflow depends on the driver aligning the fb height to the next tile boundary to push the calculated size above 4GiB. With linear buffers the effective tile height is one so that never happens, and the core already has a check for 32bit overflow of offsets[]+pitches[]*height. v2: Drop the unnecessary cast (Chris) Testcase: igt/kms_big_fb/x-tiled-addfb-size-offset-overflow Testcase: igt/kms_big_fb/y-tiled-addfb-size-offset-overflow Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180912180443.28649-1-ville.syrjala@linux.intel.com

2018-08-31drm/i915: Keep physical cursors pinned while in useChris Wilson
The optimisation inherent in commit 6a2c4232ece1 ("drm/i915: Make the physical object coherent with GTT") relies on that once we allocated a cursor we would have coherent, zero overhead access to the scanout plane holding the cursor. That is we could then do the very frequent cursor updates X enjoys with no indirection or kernel involvement. However, that all hinges on the GGTT mmap of the cursor being pinned and not require refaulting on each access -- handling such a page fault likely requires the busy GGTT to be rearranged causing a stall. A very simple fix is then to handle the physical cursor exactly like other cursors and keep its vma pinned while active.
