My attempt at allowing MST to use the higher color depths has regressed some configurations. Apparently people have setups where all MST streams will fit into the DP link with 8bpc but won't fit with higher color depths. What we really should be doing is reducing the bpc for all the streams on the same link until they start to fit. But that requires a bit more work, so in the meantime let's revert back closer to the old behavior and limit MST to at most 8bpc.

We use the context->pin_mutex to serialise updates to the OA config and the registers values written into each new context. Document this relationship and assert we do hold the context->pin_mutex as used by gen8_configure_all_contexts() to serialise updates to the OA config itself. v2: Add a white-lie for when we call intel_gt_resume() from init. v3: Lie while we have the context pinned inside atomic reset.

The bspec has just recently been updated with new cdclk values that require the use of a /2 CD2X divider rather than a /1 divider. Once we add the divider selection logic to ICL+ cdclk programming, we have pretty much the same logic we were already using on CNL, so it's simpler to drop icl_set_cdclk() completely and reuse cnl_set_cdclk() on gen11+ platforms as well. v2: - Using ICL_CDCLK_CD2X_PIPE_NONE + BXT_CDCLK_CD2X_PIPE(pipe) for TGL is correct, but looks really confusing. Add some TGL_ macros that alias these to avoid confusion. (Ville) - Use DIV_ROUND_CLOSEST rather than / when applying the divider.

During normal driver unload we attempt to disable GuC communication while it is currently stopped. This results in a nop'd call to intel_guc_ct_disable within guc_disable_communication because stop/disable rely on the same flag to prevent further comms with CT. We can avoid the call to disable and still leave communication in a satisfactory state by extracting a set of shared steps from stop/disable. This set can include guc_disable_interrupts as we do not require the single caller of guc_stop_communication to be atomic: "drm/i915/selftests: Fixup atomic reset checking". This situation (stop -> disable) only occurs during intel_uc_fini_hw, so during fini, call guc_disable_communication only if currently enabled. The symmetric calls to enable/disable remain unmodified for all other scenarios. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110943Signed-off-by:

There is a difference in BSpec's and the driver's designation of DDI ports. BSpec uses the following names: - before GEN11: BSpec/driver: port A/B/C/D etc - GEN11: BSpec/driver: port A-F - GEN12: BSpec: port A/B/C for combo PHY ports port TC1-6 for Type C PHY ports driver: port A-I. The driver's port D name matches BSpec's TC1 port name. So far power domains were named according to the BSpec designation, to make it easier to match the code against the specification. That however can be confusing when a power domain needs to be matched to a port on GEN12+. To resolve that use the driver's port A-I designation for power domain names too and rename the corresponding power wells so that they reflect the mapping from the driver's to BSpec's port name.

The CS pre-parser can pre-fetch commands across memory sync points and starting from gen12 it is able to pre-fetch across BB_START and BB_END boundaries as well, so when we emit gpu relocs the pre-parser might fetch the target location of the reloc before the memory write lands. The parser can't pre-fetch across the ctx switch, so we use a separate context to guarantee that the memory is synchronized before the parser can get to it. Note that there is no risk of the CS doing a lite restore from the reloc context to the user context, even if the two have the same hw_id, because since gen11 the CS also checks the LRCA when deciding if it can lite-restore. v2: limit new context to gen12+, release in eb_destroy, add a comment in emit_fini_breadcrumb (Chris).
