[ANNOUNCE] xf86-video-intel 2.20.14

The highlight of this release is gen4, from 965g to gm45. Quite an old bug surfaced in the shader assembly, sparking a chance to review a few design choices within that backend and experiment on fresh ways to workaround the remaining issues. * Avoid using inplace XOR'ed uploads for very large buffers https://bugs.freedesktop.org/show_bug.cgi?id=57031 * Fix the gen4/5 opacity shader https://bugs.freedesktop.org/show_bug.cgi?id=57054 * Queue a pending vblank request after flip completion https://bugs.freedesktop.org/show_bug.cgi?id=56423 * Avoid migrating an uninitialised pixmap for use as a render source https://bugs.freedesktop.org/show_bug.cgi?id=47597 * Improve handing of texture fallbacks for 830/845. https://bugs.freedesktop.org/show_bug.cgi?id=57392 Chris Wilson (45): sna: Compile against ancient libdrm sna/dri: Prevent scheduling a swap on stale buffers sna/dri: Apply the can_blit() check for CopyRegion sna: Specialise the decision for inplace xor uploads sna/gen4: Always initialise redirect sna/gen4: Do not prefer inplace non-rectilinear spans sna/gen4: Tidy emission of opacity vertex attribute sna/gen4,5: Fix the opacity shader to use the right vertex attribute sna/dri: Add a couple of more asserts to track injection of a rogue bo sna/dri: Clear the last-used-cpu flag when performing CopyRegion Remove useless indirection of intel_chipsets sna/gen6+: Tweak prefer-blt to offset latency when in rc6 sna/dri: Avoid setting off-delay after a failed flip (use-after-free) sna/dri: Add an assert that the cached DRI2 buffer is pinned for DRI sna/dri: Avoid a NULL dereference inside a DBG sna/dri: Queue a vblank-continuation after flip-completion sna: Assert that we do not create a proxy with existent GPU damage sna: Tighten a couple of assertions for damage with use_bo sna: Dispose of local copy for render sources sna: Fix bogus assertion from 03fb9ded43 sna: Add a few refcnt assertions sna: Remove the kgem_bo_is_mappable refcnt assertion from freed paths sna: Do not dispose of a shadow pixmap sna: Do not migrate uninitialised pixmaps sna: Add the missing assertion for !proxy sna: Skip uploading unintialiased pixmap data sna: Assert that we do not replace a GPU bo with a proxy sna/gen3+: Clear the render.vbo when replacing it for vertex upload Revert "uxa: Refactor early-exit paths of uxa_try_driver_composite()." sna/gen4: Use a dummy white mask to avoid the flush w/a when compositing sna/gen4: Backport the more efficient composite box emitters sna/gen4: Move the flush from inside the spans to emit_state() sna/gen4: Update render fill routines to use the dummy mask sna/gen4: Reduce the flush before performing the CA pass sna/gen4: Pass the mask channel explicitly rather than through a dummy mask sna/gen4: Set composite op before testing for a BLT compatible op sna/gen4: Force composite(WHITE, glyph) for building the glyphstring mask sna/gen4: Don't force a flush for the dirty target if the we do not read back sna/gen4: Revert changes to 965g[m] sna/g4x: Use the render pipeline more often for composite operations sna/g4x: Refine the w/a for the broken sf shader sna: Make GPU idle more consistent during wakeup sna: Transform a simple repeat pattern into range of the BLT sna: Exploit the alpha-fixup of the BLT for texture format conversions 2.20.14 release Eric Anholt (5): configure.ac: Fix bad syntax for test calls uxa/dri: Factor out the repeated swap fallback code. uxa: Add printf attribute to intel_debug_fallback(). uxa: Work around uninitialized-value warning. uxa: Refactor early-exit paths of uxa_try_driver_composite(). git tag: 2.20.14 http://xorg.freedesktop.org/archive/individual/driver/xf86-video-intel-2.20.14.tar.bz2 MD5: 17c3bc16b0bacb7f438c8c0659bd5b42 xf86-video-intel-2.20.14.tar.bz2 SHA1: 3b91178949862627c2780d9a43fbd3d22181a8aa xf86-video-intel-2.20.14.tar.bz2 SHA256: f85019afd5ddead6606bf89855d209d5369823a6e96b779fa956e0cc78d3b09b xf86-video-intel-2.20.14.tar.bz2 http://xorg.freedesktop.org/archive/individual/driver/xf86-video-intel-2.20.14.tar.gz MD5: d606cba7fe60153ced55e3dd2aa722d7 xf86-video-intel-2.20.14.tar.gz SHA1: b22874c0b182c4e9817d6d4327172486cb9fed8c xf86-video-intel-2.20.14.tar.gz SHA256: 54db225a9032e9ff493f3c9a4f4df8ec615dd2f7683843c381cba15e060dac29 xf86-video-intel-2.20.14.tar.gz -- Chris Wilson, Intel Open Source Technology Centre
