Author: Ryan Neph <[email protected]> Date: Wed Dec 16 01:18:09 2020 +0000 virgl: fix BGRA emulation artifacts during window resize On some devices, window resizing results in flashes of blue- and orange-tinted versions of the current frame until resizing is finished. This fix ensures that the emubgra tweak used for GLES virgl hosts has its enabled state flag set properly during resize events. v2: removed unrelated whitespace change Fixes: 6f68cacf619 ("virgl: Always enable emulated BGRA and swizzling unless specifically told not to") Signed-off-by: Ryan Neph <[email protected]> Reviewed-by: Gert Wollny <[email protected]> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8119> (cherry picked from commit accc2222174a90fd24ee56ce751feb6022ecc0c7) --- .pick_status.json | 2 +- src/gallium/drivers/virgl/virgl_screen.c | 4 +++- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/.pick_status.json b/.pick_status.json index 16f9282388b..6f742b17016 100644 --- a/.pick_status.json +++ b/.pick_status.json @@ -112,7 +112,7 @@ "description": "virgl: fix BGRA emulation artifacts during window resize", "nominated": true, "nomination_type": 1, - "resolution": 0, + "resolution": 1, "master_sha": null, "because_sha": "6f68cacf619f7f13bc870355709224c1f3e9bbd8" }, diff --git a/src/gallium/drivers/virgl/virgl_screen.c b/src/gallium/drivers/virgl/virgl_screen.c index 92944f4c06f..5416dc8bd10 100644 --- a/src/gallium/drivers/virgl/virgl_screen.c +++ b/src/gallium/drivers/virgl/virgl_screen.c @@ -873,7 +873,9 @@ virgl_create_screen(struct virgl_winsys *vws, const struct pipe_screen_config *c fixup_formats(&screen->caps.caps, &screen->caps.caps.v2.scanout); union virgl_caps *caps = &screen->caps.caps; - screen->tweak_gles_emulate_bgra &= !virgl_format_check_bitmask(PIPE_FORMAT_B8G8R8A8_SRGB, caps->v1.render.bitmask, false); + bool may_emulate_bgra = (caps->v2.capability_bits & VIRGL_CAP_APP_TWEAK_SUPPORT); + screen->tweak_gles_emulate_bgra &= !virgl_format_check_bitmask( + PIPE_FORMAT_B8G8R8A8_SRGB, caps->v1.render.bitmask, may_emulate_bgra); screen->refcnt = 1; slab_create_parent(&screen->transfer_pool, sizeof(struct virgl_transfer), 16); _______________________________________________ mesa-commit mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-commit
