Multicast/replicated (MCR) registers on Intel hardware are a purely GT-specific concept. Rather than leaving MCR register handling spread across several places throughout the driver (intel_uncore.c, intel_gt.c, etc.) with confusing combinations of handler functions living in different namespaces, let's consolidate it all into a single place (intel_gt_mcr.c) and provide a more consistent and clearly-documented interface for the rest of the driver to access such registers: * intel_gt_mcr_read -- unicast read from specific instance * intel_gt_mcr_read_any[_fw] -- unicast read from any non-terminated instance * intel_gt_mcr_unicast_write -- unicast write to specific instance * intel_gt_mcr_multicast_write[_fw] -- multicast write to all instances Matt Roper (2): drm/i915/gt: Move multicast register handling to a dedicated file drm/i915/gt: Cleanup interface for MCR operations drivers/gpu/drm/i915/Makefile | 1 + drivers/gpu/drm/i915/gem/i915_gem_stolen.c | 3 +- drivers/gpu/drm/i915/gt/intel_engine_cs.c | 36 +- drivers/gpu/drm/i915/gt/intel_gt.c | 297 +----------- drivers/gpu/drm/i915/gt/intel_gt.h | 15 - drivers/gpu/drm/i915/gt/intel_gt_debugfs.c | 3 +- drivers/gpu/drm/i915/gt/intel_gt_mcr.c | 483 ++++++++++++++++++++ drivers/gpu/drm/i915/gt/intel_gt_mcr.h | 34 ++ drivers/gpu/drm/i915/gt/intel_region_lmem.c | 5 +- drivers/gpu/drm/i915/gt/intel_workarounds.c | 9 +- drivers/gpu/drm/i915/gt/uc/intel_guc_ads.c | 3 +- drivers/gpu/drm/i915/i915_drv.h | 2 - drivers/gpu/drm/i915/intel_uncore.c | 112 ----- drivers/gpu/drm/i915/intel_uncore.h | 8 - 14 files changed, 551 insertions(+), 460 deletions(-) create mode 100644 drivers/gpu/drm/i915/gt/intel_gt_mcr.c create mode 100644 drivers/gpu/drm/i915/gt/intel_gt_mcr.h -- 2.35.3
