drm/i915/hti: abstract hti handling

2022-11-17T14:12:56+00:00

The HTI or HDPORT handling is sprinkled around. Centralize to one place. Add a note about how subtle the mapping from HDPORT_STATE register to dpll mask actually is.

drm/i915/mtl: Handle wopcm per-GT and limit calculations.

2022-11-14T18:11:47+00:00

With MTL standalone media architecture the wopcm layout has changed, with separate partitioning in WOPCM for the root GT GuC and the media GT GuC. The size of WOPCM is 4MB with the lower 2MB reserved for the media GT and the upper 2MB for the root GT. Given that MTL has GuC deprivilege, the WOPCM registers are pre-locked by the bios. Therefore, we can skip all the math for the partitioning and just limit ourselves to sanity-checking the values. v2: fix makefile file ordering (Jani) v3: drop XELPM_SAMEDIA_WOPCM_SIZE, check huc instead of VDBOX (John) v4: further clarify commit message, remove blank line (John) Signed-off-by: Aravind Iddamsetty Signed-off-by: Daniele Ceraolo Spurio Cc: Matt Roper Cc: John Harrison Cc: Alan Previn Cc: Jani Nikula Reviewed-by: John Harrison Link: https://patchwork.freedesktop.org/patch/msgid/20221108020600.3575467-5-daniele.ceraolospurio@intel.com

drm/i915/tgl+: Add locking around DKL PHY register accesses

2022-10-26T12:51:13+00:00

Accessing the TypeC DKL PHY registers during modeset-commit, -verification, DP link-retraining and AUX power well toggling is racy due to these code paths being concurrent and the PHY register bank selection register (HIP_INDEX_REG) being shared between PHY instances (aka TC ports) and the bank selection being not atomic wrt. the actual PHY register access. Add the required locking around each PHY register bank selection-> register access sequence. Kudos to Ville for noticing the race conditions. v2: - Add the DKL PHY register accessors to intel_dkl_phy.[ch]. (Jani) - Make the DKL_REG_TC_PORT macro independent of PHY internals. - Move initing the DKL PHY lock to a more logical place. v3: - Fix parameter reuse in the DKL_REG_TC_PORT definition. - Document the usage of phy_lock. v4: - Fix adding TC_PORT_1 offset in the DKL_REG_TC_PORT definition.
