Bug ID: 107012
Summary: [PATCH] Radeon SI driver not architecture safe,
crashes on ppc64[el]
Product: Mesa
Version: git
Hardware: PowerPC
OS: All
Status: NEW
Severity: major
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org

Fix crashes
color_interp_vgpr_index was declared as a generic char value. Because signed
values are used in this variable, the result was not safe across architectures
and crashed on ppc64[el] and arm systems.
The atttached patch declares color_interp_vgpr_index as a signed type, and has
been verified to work with alien-arena, glxgears, and Flightgear, all of which
were crashing before the patch.
