Bug ID: 98025
Summary: [radeonsi] incorrect primitive restart index used
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi

Apitrace reproducing the issue
With radeonsi, If primitive restart is enabled for two consecutive draws which
use different primitive restart indices, then the first draw's primitive
restart index is incorrectly used for the second draw.
The attached apitrace reproduces the issue. The first and second draws should
draw the same thing. The first is using a primitive restart index of
0xFFFFFFFF, and the second is using 0xFFFF (these are set using fixed index
primitive restart and different index types).
