2020-03-17drm/i915/perf: remove redundant power configuration register overrideLionel Landwerlin
The caller of i915_oa_init_reg_state() already sets this. Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200317132222.2638719-2-lionel.g.landwerlin@intel.com
2020-03-17drm/i915/perf: remove generated codeLionel Landwerlin
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: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200317132222.2638719-1-lionel.g.landwerlin@intel.com

Without this protection most of linux installation was recommending nomodeset option during installation that was getting stick there after installation.

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.

2020-03-10drm/i915/display: Deactive FBC in fastsets when disabled by parameterJosé Roberto de Souza
Most of the kms_frontbuffer_tracking tests disables the feature being tested, draw, get the CRC then enable the feature, draw again, get the CRC and check if it matches. Some times it is able to do that with a fastset, so intel_pre_plane_update() is executed but intel_fbc_can_flip_nuke() was not checking if FBC is now enabled in this CRTC leaving FBC active and

2020-03-10drm/i915/mst: Hookup DRM DP MST late_register/early_unregister callbacksLyude Paul
i915 can enable aux device nodes for DP MST by calling drm_dp_mst_connector_late_register()/ drm_dp_mst_connector_early_unregister(), so let's hook that up. Changes since v1: * Call intel_connector_register/unregister() from intel_dp_mst_connector_late_register/unregister() so we don't lose error injection - Ville Syrjälä Changes since v2: * Don't forget to clean up if intel_connector_register() fails - Ville Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: "Lee, Shawn C" <shawn.c.lee@intel.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200310195122.1590925-1-lyude@redhat.com
2020-03-10drm/i915: Improve the start alignment of bonded pairsChris Wilson
Always wait on the start of the signaler request to reduce the problem of dequeueing the bonded pair too early -- we want both payloads to start at the same time, with no latency, and yet still allow others to make full use of the slack in the system. This reduce the amount of time we spend waiting on the semaphore used to synchronise the start of the bonded payload.
