Bug ID: 92236
Summary: [ColorTiling2D] R600 BARTS radeon: pipe_context->clear
with color tiling enabled doesn't immediately affect
color buffer
Product: Mesa
Version: git
Hardware: x86 (IA32)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r600
Assignee: dri-devel at lists.freedesktop.org
Reporter: siro at das-labor.org
QA Contact: dri-devel at lists.freedesktop.org
There's an open Gallium nine bug: https://github.com/iXit/Mesa-3D/issues/138
It looks like pipe_context->clear called with PIPE_CLEAR_COLOR isn't applied
immediately to the buffer.
As nine mimics swap-chains, the buffer is reused after some frames resulting in
"delayed" presentation.
The problem doesn't exist with R600_DEBUG=notiling and it doesn't exists when
using pipe_context->clear_render_target instead.
Tested with mesa git: https://github.com/iXit/Mesa-3D/
