Subject: [PATCH v5 1/3] drm/i915: fix whitelist selftests with readonly registers
Date: Tue, 25 Jun 2019 21:22:55 +0300 [thread overview]
Message-ID: <20190625182257.22075-2-lionel.g.landwerlin@intel.com> (raw)
In-Reply-To: <20190625182257.22075-1-lionel.g.landwerlin@intel.com>
When a register is readonly there is not much we can tell about its
value (apart from its default value?). This can be covered by tests
exercising the value of the register from userspace.
For PS_INVOCATION_COUNT we've got the following piglit tests :
KHR-GL45.pipeline_statistics_query_tests_ARB.functional_fragment_shader_invocations
Vulkan CTS tests :
dEQP-VK.query_pool.statistics_query.fragment_shader_invocations.*
