And it refactors singleton PSR to Multi Transcoder supportable PSR. And this moves and renames the i915_psr structure of drm_i915_private's to intel_dp's intel_psr structure. It also causes changes in PSR interrupt handling routine for supporting multiple transcoders. But it does not change the scenario and timing of enabling and disabling PSR. v2: Fix indentation and add comments v3: Remove Blank line v4: Rebased v5: Rebased and Addressed Anshuman's review comment. - Move calling of intel_psr_init() to intel_dp_init_connector() Signed-off-by: Gwan-gyeong Mun Cc: José Roberto de Souza Cc: Juha-Pekka Heikkila Cc: Anshuman Gupta --- drivers/gpu/drm/i915/display/intel_ddi.c | 3 + drivers/gpu/drm/i915/display/intel_display.c | 4 - .../drm/i915/display/intel_display_debugfs.c | 111 ++-- .../drm/i915/display/intel_display_types.h | 38 ++ drivers/gpu/drm/i915/display/intel_dp.c | 23 +- drivers/gpu/drm/i915/display/intel_psr.c | 585 ++++++++++-------- drivers/gpu/drm/i915/display/intel_psr.h | 14 +- drivers/gpu/drm/i915/display/intel_sprite.c | 6 +- drivers/gpu/drm/i915/i915_drv.h | 38 -- drivers/gpu/drm/i915/i915_irq.c | 49 +- 10 files changed, 491 insertions(+), 380 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_ddi.c b/drivers/gpu/drm/i915/display/intel_ddi.c index 6863236df1d0..4b87f72cb9c0 100644 --- a/drivers/gpu/drm/i915/display/intel_ddi.c +++ b/drivers/gpu/drm/i915/display/intel_ddi.c @@ -4320,7 +4320,10 @@ static void intel_ddi_update_pipe_dp(struct intel_atomic_state *state, intel_ddi_set_dp_msa(crtc_state, conn_state);
