[igt-dev] [PATCH i-g-t] tests/i915: skip gem_set_caching call for mtl

Vikas Srivastava vikas.srivastava at intel.com
Thu Mar 9 14:19:40 UTC 2023


Call to gem_set_caching skips the test since i915_gem_set_caching_ioctl is
deprecated for MTL. To avoid this added the return value check for
0 or EOPNOTSUPP in __gem_set_caching.

FIXME: This is a temp solution to fix the IGT test issues where
set caching call is used , there is alternate API available
but support not yet available to use that.Once set_pat_index
support available need to bring that change replacing this one.
