A little bit of history : Back when i915-perf was introduced (4.13), there was no way to dynamically add new OA configurations to i915. Only the generated configs baked in at build time were allowed. It quickly became obvious that we would need to allow applications to upload their own configurations, for instance to be able to test new ones, and so by the next stable version (4.14) we added uAPIs to allow uploading new configurations. When adding that capability, we took the opportunity to remove most HW configurations except the TestOa one which is a configuration IGT would rely on to verify that the HW is outputting correct values. At the time it made sense to have that confiuration in at the same time a given HW platform added to the i915-perf driver. Now that IGT has become the reference point for HW configurations (see commit 53f8f541ca ("lib: Add i915_perf library"), previously this was located in the GPUTop repository), the need for having those configurations in i915-perf is gone. On the Mesa side, we haven't relied on this test configuration for a while. The MDAPI library always required 4.14 feature level and always loaded its configuration into i915. I'm sure nobody will miss this generated stuff in i915 :) v2: Fix selftests by creating an empty config v3: Fix unlocking on allocation error (Dan Carpenter) v4: Fixup checkpatch warnings v5: Fix incorrect unlock in error path (Umesh) Signed-off-by:Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200317132222.2638719-1-lionel.g.landwerlin@intel.com

We have a few TGL machines in our CI and it is mostly green with failures in tests that will not impact future Linux installations. Also there is no warnings, errors, flickering or any visual defects while doing ordinary tasks like browsing and editing documents in a dual monitor setup. As a reminder i915.require_force_probe was created to protect future Linux installation's iso images that might contain a kernel from the enabling time of the new platform. Without this protection most of linux installation was recommending nomodeset option during installation that was getting stick there after installation.

This workaround appears under two different numbers (and with somewhat confused stepping applicability on ICL). Ultimately it appears we should just implement this for all stepping of ICL and EHL. Note that this is identical to Wa_1407928979:tgl that already exists in our driver too...yet another number referencing the same actual workaround. Signed-off-by:

The bspec description for this workaround tells us to program 0xFFFF_FFFF into both FBC_RT_BASE_ADDR_REGISTER_* registers, but we've previously found that this leads to failures in CI. Our suspicion is that the failures are caused by this valid turning on the "address valid bit" even though we're intentionally supplying an invalid address. Experimentation has shown that setting all bits _except_ for the RT_VALID bit seems to avoid these failures. v2: - Mask off the RT_VALID bit. Experimentation with CI trybot indicates that this is necessary to avoid reset failures on BCS. v3: - Program RT_BASE before RT_BASE_UPPER so that the valid bit is turned off by the first write.
