In this mode, skylake scaler does either chroma-upsampling or chroma-upsampling and resolution scaling v2: Review comments from Ville addressed NV12 case to be checked first for setting the scaler v3: Rebased (me) v4: Rebased (me) v5: Missed the Tested-by/Reviewed-by in the previous series Adding the same to commit message in this version. v6: Rebased (me) v7: Rebased (me) v8: Rebased (me) Restricting the NV12 change for scaler to BXT and KBL in this series. v9: Rebased (me) v10: As of now, NV12 has been tested on Gen9 and Gen10. However, code is applicable to all GEN >= 9. Hence making that change to keep it generic. Comments under v8 is not valid anymore. v11: Addressed review comments by Shashank Sharma. For Gen10+, the scaler mode to be set it planar or normal (single bit). Changed the code to be applicable to all Gen. v12: Addressed review comments from Shashank Sharma For Gen9 (apart from GLK) bits 28:29 to be programmed in PS_CTRL for NV12. For GLK and Gen10+, bit 29 to be set for all Planar. v13: Addressed review comments from Juha-Pekka Heikkila "NV12 not to be supported by SKL" Adding Reviewed by tag from Shashank Shamr v14: Added reviewed by from Juha-Pekka Heikkila v15: Rebased the series Tested-by: Clinton Taylor Reviewed-by: Juha-Pekka Heikkila Reviewed-by: Shashank Sharma Reviewed-by: Clinton Taylor Signed-off-by: Chandra Konduru Signed-off-by: Nabendu Maiti Signed-off-by: Vidya Srinivas --- drivers/gpu/drm/i915/i915_reg.h | 2 ++ drivers/gpu/drm/i915/intel_atomic.c | 14 ++++++++++++-- 2 files changed, 14 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 1f858e2..fb10602 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -6664,6 +6664,8 @@ enum { #define PS_SCALER_MODE_MASK (3 << 28) #define PS_SCALER_MODE_DYN (0 << 28) #define PS_SCALER_MODE_HQ (1 << 28) +#define SKL_PS_SCALER_MODE_NV12 (2 << 28) +#define PS_SCALER_MODE_PLANAR (1 << 29) #define PS_PLANE_SEL_MASK (7 << 25) #define PS_PLANE_SEL(plane) (((plane) + 1) << 25) #define PS_FILTER_MASK (3 << 23) diff --git a/drivers/gpu/drm/i915/intel_atomic.c b/drivers/gpu/drm/i915/intel_atomic.c index e9fb6920..bb8c168 100644 --- a/drivers/gpu/drm/i915/intel_atomic.c +++ b/drivers/gpu/drm/i915/intel_atomic.c @@ -328,8 +328,18 @@ int intel_atomic_setup_scalers(struct drm_i915_private *dev_priv, } /* set scaler mode */ - if (IS_GEMINILAKE(dev_priv) || IS_CANNONLAKE(dev_priv)) { - scaler_state->scalers[*scaler_id].mode = 0; + if ((INTEL_GEN(dev_priv) >= 9) && + plane_state && plane_state->base.fb && + plane_state->base.fb->format->format == + DRM_FORMAT_NV12) { + if (INTEL_GEN(dev_priv) == 9 && + !IS_GEMINILAKE(dev_priv) && + !IS_SKYLAKE(dev_priv)) + scaler_state->scalers[*scaler_id].mode = + SKL_PS_SCALER_MODE_NV12; + else + scaler_state->scalers[*scaler_id].mode = + PS_SCALER_MODE_PLANAR; } else if (num_scalers_need == 1 && intel_crtc->pipe != PIPE_C) { /* * when only 1 scaler is in use on either pipe A or B,
