Subject: Re: [igt-dev] [PATCH i-g-t v4 1/1] gem_ctx_isolation.c - Gen11 enabling for context isolation test
Date: Tue, 5 Mar 2019 12:46:51 -0800 [thread overview]
Message-ID: <20190305204650.GA31562@dbstims-dev.fm.intel.com> (raw)

CS_CHICKEN1 is not privileged anymore (as of Gen11), as evidenced
by its absence from the kernel whitelist for Gen11 combined with the
successful execution on ICL of the tests added by your recent patch
"i915/gem_ctx_isolation: Sanitycheck nonpriv access".
