[PATCH i-g-t 1/2] lib/gpgpu_shader: Add x_offset parameter for gpgpu_shader__write_on_exception

Christoph Manszewski christoph.manszewski at intel.com
Wed Sep 25 13:30:02 UTC 2024


Currently gpgpu_shader__write_on_exception always writes the first
column equal to thread group ID x. Make it possible to specify an offset
from that value.
