From f9a7b19c484067fdcc5972c88ab6f06898adc40d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 7 Oct 2021 02:57:01 +0300 Subject: [PATCH] drm/i915: Move the pxp plane state computation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit No real reason to have this pxp state computation in intel_atomic_check_planes(). Just stuff it into skl_plane_check(). There was also some funny state copying being done from the old plane state to the new plane state when the plane is anyway disabled. The one thing we presumably must remember to do is copy over the decrypt state when assigning a Y plane for planar YCbCr scanout, so that the Y plane's PLANE_SURF will get the appropriate bit set. The force_black thing should not matter as I'm pretty sure all that stuff is ignored for the Y plane. I suppose this was the reason for the odd placement for the state computation, but I see no reason to deviate from the standard way of doing these things. This also guarantees that we don't calculate things differently between the linked UV and Y plane. v2: Only do stuff for icl+ since 'force_black' depends on the plane CSC which is an icl+ feature Cc: Anshuman Gupta Cc: Daniele Ceraolo Spurio Cc: Juston Li Cc: Rodrigo Vivi Cc: Uma Shankar Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20211006235704.28894-2-ville.syrjala@linux.intel.com Reviewed-by: Juston Li #v1 --- drivers/gpu/drm/i915/display/intel_display.c | 31 +--------------------- drivers/gpu/drm/i915/display/skl_universal_plane.c | 17 ++++++++++++ 2 files changed, 18 insertions(+), 30 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index ff598b6..ce5d663 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -70,8 +70,6 @@ #include "gt/gen8_ppgtt.h" -#include "pxp/intel_pxp.h" - #include "g4x_dp.h" #include "g4x_hdmi.h" #include "i915_drv.h" @@ -6238,6 +6236,7 @@ static int icl_check_nv12_planes(struct intel_crtc_state *crtc_state) linked_state->ctl = plane_state->ctl | PLANE_CTL_YUV420_Y_PLANE; linked_state->color_ctl = plane_state->color_ctl; linked_state->view = plane_state->view; + linked_state->decrypt = plane_state->decrypt; intel_plane_copy_hw_state(linked_state, plane_state); linked_state->uapi.src = plane_state->uapi.src; @@ -8600,28 +8599,13 @@ static int intel_bigjoiner_add_affected_planes(struct intel_atomic_state *state) return 0; } -static bool bo_has_valid_encryption(struct drm_i915_gem_object *obj) -{ - struct drm_i915_private *i915 = to_i915(obj->base.dev); - - return intel_pxp_key_check(&i915->gt.pxp, obj, false) == 0; -} - -static bool pxp_is_borked(struct drm_i915_gem_object *obj) -{ - return i915_gem_object_is_protected(obj) && !bo_has_valid_encryption(obj); -} - static int intel_atomic_check_planes(struct intel_atomic_state *state) { struct drm_i915_private *dev_priv = to_i915(state->base.dev); struct intel_crtc_state *old_crtc_state, *new_crtc_state; struct intel_plane_state *plane_state; struct intel_plane *plane; - struct intel_plane_state *new_plane_state; - struct intel_plane_state *old_plane_state; struct intel_crtc *crtc; - const struct drm_framebuffer *fb; int i, ret; ret = icl_add_linked_planes(state); @@ -8669,19 +8653,6 @@ static int intel_atomic_check_planes(struct intel_atomic_state *state) return ret; } - for_each_new_intel_plane_in_state(state, plane, plane_state, i) { - new_plane_state = intel_atomic_get_new_plane_state(state, plane); - old_plane_state = intel_atomic_get_old_plane_state(state, plane); - fb = new_plane_state->hw.fb; - if (fb) { - new_plane_state->decrypt = bo_has_valid_encryption(intel_fb_obj(fb)); - new_plane_state->force_black = pxp_is_borked(intel_fb_obj(fb)); - } else { - new_plane_state->decrypt = old_plane_state->decrypt; - new_plane_state->force_black = old_plane_state->force_black; - } - } - return 0; } diff --git a/drivers/gpu/drm/i915/display/skl_universal_plane.c b/drivers/gpu/drm/i915/display/skl_universal_plane.c index a0e53a3..3ee403e 100644 --- a/drivers/gpu/drm/i915/display/skl_universal_plane.c +++ b/drivers/gpu/drm/i915/display/skl_universal_plane.c @@ -1737,6 +1737,18 @@ static bool skl_fb_scalable(const struct drm_framebuffer *fb) } } +static bool bo_has_valid_encryption(struct drm_i915_gem_object *obj) +{ + struct drm_i915_private *i915 = to_i915(obj->base.dev); + + return intel_pxp_key_check(&i915->gt.pxp, obj, false) == 0; +} + +static bool pxp_is_borked(struct drm_i915_gem_object *obj) +{ + return i915_gem_object_is_protected(obj) && !bo_has_valid_encryption(obj); +} + static int skl_plane_check(struct intel_crtc_state *crtc_state, struct intel_plane_state *plane_state) { @@ -1781,6 +1793,11 @@ static int skl_plane_check(struct intel_crtc_state *crtc_state, if (ret) return ret; + if (DISPLAY_VER(dev_priv) >= 11) { + plane_state->decrypt = bo_has_valid_encryption(intel_fb_obj(fb)); + plane_state->force_black = pxp_is_borked(intel_fb_obj(fb)); + } + /* HW only has 8 bits pixel precision, disable plane if invisible */ if (!(plane_state->hw.alpha >> 8)) plane_state->uapi.visible = false; -- 2.7.4
