FBC will be enabled on planes first come first served basis until the userspace can select one of these FBC capable planes explicitly. v2: - avoid fbc->state.plane check in intel_fbc_check_plane (Ville) - simplify plane binding register writes (Matt) - Update the subject to reflect that fbc can be enabled only in the first three planes (Matt) v3: - use icl_is_hdr_plane(), use wrapper macro for plane binding register access, comments update and patch split (Ville) v4: - update to the plane binding register access macro Bspec: 69560 Signed-off-by: Vinod Govindapillai --- drivers/gpu/drm/i915/display/intel_fbc.c | 3 +++ drivers/gpu/drm/i915/display/skl_universal_plane.c | 9 ++++++--- drivers/gpu/drm/i915/i915_reg.h | 2 ++ 3 files changed, 11 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_fbc.c b/drivers/gpu/drm/i915/display/intel_fbc.c index 66c8aed07bbc..a3999ad95a19 100644 --- a/drivers/gpu/drm/i915/display/intel_fbc.c +++ b/drivers/gpu/drm/i915/display/intel_fbc.c @@ -660,6 +660,9 @@ static u32 ivb_dpfc_ctl(struct intel_fbc *fbc) if (IS_IVYBRIDGE(i915)) dpfc_ctl |= DPFC_CTL_PLANE_IVB(fbc_state->plane->i9xx_plane); + if (DISPLAY_VER(i915) >= 20) + dpfc_ctl |= DPFC_CTL_PLANE_BINDING(fbc_state->plane->id); + if (fbc_state->fence_id >= 0) dpfc_ctl |= DPFC_CTL_FENCE_EN_IVB; diff --git a/drivers/gpu/drm/i915/display/skl_universal_plane.c b/drivers/gpu/drm/i915/display/skl_universal_plane.c index 4d01c7ae4485..8f946c5a2fd8 100644 --- a/drivers/gpu/drm/i915/display/skl_universal_plane.c +++ b/drivers/gpu/drm/i915/display/skl_universal_plane.c @@ -1956,13 +1956,16 @@ static enum intel_fbc_id skl_fbc_id_for_pipe(enum pipe pipe) return pipe - PIPE_A + INTEL_FBC_A; } -static bool skl_plane_has_fbc(struct drm_i915_private *dev_priv, +static bool skl_plane_has_fbc(struct drm_i915_private *i915, enum intel_fbc_id fbc_id, enum plane_id plane_id) { - if ((DISPLAY_RUNTIME_INFO(dev_priv)->fbc_mask & BIT(fbc_id)) == 0) + if ((DISPLAY_RUNTIME_INFO(i915)->fbc_mask & BIT(fbc_id)) == 0) return false; - return plane_id == PLANE_PRIMARY; + if (DISPLAY_VER(i915) >= 20) + return icl_is_hdr_plane(i915, plane_id); + else + return plane_id == PLANE_PRIMARY; } static struct intel_fbc *skl_plane_fbc(struct drm_i915_private *dev_priv, diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index aefad14ab27a..d44ac6f1c052 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -1327,6 +1327,8 @@ #define DPFC_CTL_PLANE_IVB(i9xx_plane) REG_FIELD_PREP(DPFC_CTL_PLANE_MASK_IVB, (i9xx_plane)) #define DPFC_CTL_FENCE_EN_IVB REG_BIT(28) /* ivb+ */ #define DPFC_CTL_PERSISTENT_MODE REG_BIT(25) /* g4x-snb */ +#define DPFC_CTL_PLANE_BINDING_MASK REG_GENMASK(12, 11) /* lnl+ */ +#define DPFC_CTL_PLANE_BINDING(plane_id) REG_FIELD_PREP(DPFC_CTL_PLANE_BINDING_MASK, (plane_id)) #define DPFC_CTL_FALSE_COLOR REG_BIT(10) /* ivb+ */ #define DPFC_CTL_SR_EN REG_BIT(10) /* g4x only */ #define DPFC_CTL_SR_EXIT_DIS REG_BIT(9) /* g4x only */
