* drm/i915: Add plane alpha blending support, v2.Maarten Lankhorst2018-10-021-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | The only time we should start FBC is when we have waited a vblank after the atomic update. We've already forced a vblank wait by doing wait_for_flip_done before intel_post_plane_update(), so we don't need to wait a second time before enabling. Removing the worker simplifies the code and removes possible race conditions, like happening in 103167.

* drm/i915/gen9, gen10: Disable FBC on planes with a misaligned Y-offsetImre Deak2018-03-021-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling FBC on a plane having a Y-offset that isn't divisible by 4 may cause pipe FIFO underruns and flickers, so disable FBC on such a config. I tried the followings to work around the issue: - enable each HW work around in ILK_DPFC_CHICKEN - disable each compression algorithm in ILK_DPFC_CONTROL - disable low-power watermarks None of the above got rid of the problem. I haven't found this issue in the Bspec/WA database either. Besides the igt testcase below (yet to be merged) an easy way to reproduce the issue is to enable a plane with FBC and a plane Y-offset not aligned to 4 and then just enable/disable FBC in a loop, keeping the plane enabled. I could trigger the problem on BXT/GLK/SKL/CNL, so assume for now that it's only present on GEN9 and GEN10. v2: (Ville) - Run the test/apply the WA on CNL as well. - Use IS_GEN() instead of INTEL_GEN(). - Fix spelling.

* drm/i915: enable FBC on gen9+ tooPaulo Zanoni2017-01-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Gen9+ platforms have been seeing a lot of screen flickerings and underruns, so I never felt comfortable in enabling FBC on these platforms since I didn't want to throw yet another feature on top of the already complex problem. We now have code that automatically disables FBC if we ever get an underrun, and the screen flickerings seem to be mostly gone, so it may be a good time to try to finally enable FBC by default on the newer platforms. Besides, BDW FBC has been working fine over the year, which gives me a little more confidence now. For a little more information, please refer to commit a98ee79317b4 ("drm/i915/fbc: enable FBC by default on HSW and BDW"). v2: Enable not only on SKL, but for everything new (Daniel). v3: Rebase after the intel_sanitize_fbc_option() change. v4: New rebase after 8 months, drop expired R-B tags.

|\ | | | | | | | | | | | | | | | | | | | | | | git://anongit.freedesktop.org/git/drm-misc into drm-intel-next-queued Directly merge drm-misc into drm-intel since Dave is on vacation and we need the various drm-misc patches (fb format rework, drm mm fixes, selftest framework and others). Also pulled back -rc2 in first to resync with drm-intel-fixes and make sure I can reuse the exact rerere solutions from drm-tip for safety, and because I'm lazy.

| | | | | | | | | | | | | | | | | | | | | | | | Rather than store the pixel format and look up the format info as needed, let's just store a pointer to the format info directly and speed up our lookups.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't even tell the mm allocator to handle the first page of stolen on the affected platforms. This means that we won't inherit the FB in case the BIOS decides to put it at the start of stolen. But the BIOS should not be putting it at the start of stolen since it's going to get corrupted. I suppose the bug here is that some pixels at the very top of the screen will be corrupted, so it's not exactly easy to notice. We have confirmation that the first page of stolen does actually get corrupted, so I really think we should do this in order to avoid any possible future headaches, even if that means losing BIOS framebuffer inheritance. Let's not use the HW in a way it's not supposed to be used. Notice that now ggtt->stolen_usable_size won't reflect the ending address of the stolen usable range anymore, so we have to fix the places that rely on this. To simplify, we'll just use U64_MAX. v2: don't even put the first page on the mm (Chris) v3: drm_mm_init() takes size instead of end as argument (Ville) v4: add a comment explaining the reserved ranges (Chris) use 0 for start and U64_MAX for end when possible (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94605 Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1481808235-27607-1-git-send-email-paulo.r.zanoni@intel.com

| | | | | | | | | | Because it's shorter, easier to read, newer and cooler. And I don't think anybody else has pending FBC patches right now, so the conflicts should be minimal.
