[igt-dev] [PATCH i-g-t v3] tests/i915: skip gem_set_caching call for mtl

Vikas Srivastava vikas.srivastava at intel.com
Thu Mar 30 06:33:29 UTC 2023


Call to gem_set_caching skips the test since i915_gem_set_caching_ioctl is
deprecated for MTL. To avoid this add the check for set caching supported
platforms.

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.
