2022-07-28drm/i915/d12+: Disable DMC handlers during loading/disabling the firmwareImre Deak1-0/+1
Disable the DMC event handlers before loading the firmware and after uninitializing the display, to make sure the firmware is inactive. This matches the Bspec "Sequences for Display C5 and C6" page for GEN12+. Add a TODO comment for doing the same on pre-GEN12 platforms. v2: - Add a macro for the number of event handlers. - Disable the event handlers only on GEN12+. - s/dev_priv/i915/ in docbook comment.

2022-02-02drm/i915: Only include i915_reg.h from .c filesMatt Roper1-1/+1
Several of our i915 header files, have been including i915_reg.h. This means that any change to i915_reg.h will trigger a full rebuild of pretty much every file of the driver, even those that don't have any kind of register access. Let's delete the i915_reg.h include from all headers and add an explicit include from the .c files that truly need the register definitions; those that need a definition of i915_reg_t for a function definition can get it from i915_reg_defs.h instead. We also remove two non-register #define's (VLV_DISPLAY_BASE and GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the i915_reg.h include from a couple of headers. There's probably a lot more header dependency optimization possible, but the changes here roughly cut the number of files compiled after 'touch i915_reg.h' in half --- a good first step.

2021-06-21drm/i915/xelpd: Pipe A DMC pluggingAnusha Srivatsa1-0/+4
This patch adds Pipe A plumbing to the already existing parsing and loading functions which is taken care of in the prep patches. Adding MAX_DMC_FW to keep track for both Main and Pipe A DMC while loading the respective blobs. Also adding present field in dmc_info. s/find_dmc_fw_offset/csr_set_dmc_fw_offset. While at it add fw_info_matches_stepping() helper. CSR_PROGRAM() should now take the starting address of the particular blob (Main or Pipe) and not hardcode it. v2: Add dmc_offset and start_mmioaddr fields for dmc_info struct. v3: Add a missing corner cases of stepping-substepping combination in fw_info_matches_stepping() helper. v4: Add macro for start_mmioaddr for V1 package.
