Subject: [PATCH] radeonsi: On Aarch64 force persistent buffers to GTT
|
|
|
|
This fixes a glamore corruption issue on the HoneyComb and by
|
|
internet reports should also fix problems seen on Huaweii
|
|
Kunpeng hardware.
|
|
|
|
The root cause of the corruption needs to be worked out, but
|
|
this patch also adds a noticable performance improvement. The
|
|
aquarium webgl demo under chromium increases from 39-49 FPS
|
|
when 5000 fish being rendered is selected. Glmark scores also
|
|
improve by ~200 with no specific tests showing any regression.
