From 4e0bbc316ef2a7d804cef3e0247fd782382f5bd4 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Sat, 2 Nov 2013 21:07:07 -0700 Subject: [PATCH] drm/i915/bdw: display stuff Just enough to make the code not barf... Init BDW display to look like HSW. For the simulator this should be fine, but this will probably require more work. Signed-off-by: Ben Widawsky [danvet: Add a FIXME comment about RCS flips being untested on bdw. Also add a note that hblank events are reserved on bdw+ in DERRMR.] Reviewed-by: Daniel Vetter Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_reg.h | 1 + drivers/gpu/drm/i915/intel_display.c | 3 ++- drivers/gpu/drm/i915/intel_sprite.c | 1 + 3 files changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index f897a7092ce0..48c3aef5acaa 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -743,6 +743,7 @@ #define FPGA_DBG_RM_NOCLAIM (1<<31) #define DERRMR 0x44050 +/* Note that HBLANK events are reserved on bdw+ */ #define DERRMR_PIPEA_SCANLINE (1<<0) #define DERRMR_PIPEA_PRI_FLIP_DONE (1<<1) #define DERRMR_PIPEA_SPR_FLIP_DONE (1<<2) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index f34252d134b6..d5eb5a4a9cf6 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -10309,7 +10309,7 @@ static void intel_init_display(struct drm_device *dev) dev_priv->display.write_eld = ironlake_write_eld; dev_priv->display.modeset_global_resources = ivb_modeset_global_resources; - } else if (IS_HASWELL(dev)) { + } else if (IS_HASWELL(dev) || IS_GEN8(dev)) { dev_priv->display.fdi_link_train = hsw_fdi_link_train; dev_priv->display.write_eld = haswell_write_eld; dev_priv->display.modeset_global_resources = @@ -10340,6 +10340,7 @@ static void intel_init_display(struct drm_device *dev) dev_priv->display.queue_flip = intel_gen6_queue_flip; break; case 7: + case 8: /* FIXME(BDW): Check that the gen8 RCS flip works. */ dev_priv->display.queue_flip = intel_gen7_queue_flip; break; } diff --git a/drivers/gpu/drm/i915/intel_sprite.c b/drivers/gpu/drm/i915/intel_sprite.c index 8afaad6bcc48..f8b265c2b178 100644 --- a/drivers/gpu/drm/i915/intel_sprite.c +++ b/drivers/gpu/drm/i915/intel_sprite.c @@ -1092,6 +1092,7 @@ intel_plane_init(struct drm_device *dev, enum pipe pipe, int plane) break; case 7: + case 8: if (IS_IVYBRIDGE(dev)) { intel_plane->can_scale = true; intel_plane->max_downscale = 2; -- 2.39.5
