From 5e6037c88ad5f052e317a56cff54df40b7e82e5f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 12 Mar 2019 22:58:42 +0200 Subject: [PATCH] drm/i915: Move some variables to tighter scope MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Clean up skl_allocate_pipe_ddb() a bit by moving the 'wm' variable to tighter scope. We'll also consitify it where appropriate. Also initialize plane_alloc/uv_plane_alloc when decrlaring them rather than later. v2: Update commit message (Matt) Cc: Neel Desai Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20190312205844.6339-8-ville.syrjala@linux.intel.com Reviewed-by: Matt Roper --- drivers/gpu/drm/i915/intel_pm.c | 23 +++++++++++++---------- 1 file changed, 13 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c index e7bc38f..0b3e29eb 100644 --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -4344,7 +4344,6 @@ skl_allocate_pipe_ddb(struct intel_crtc_state *cstate, struct drm_i915_private *dev_priv = to_i915(crtc->dev); struct intel_crtc *intel_crtc = to_intel_crtc(crtc); struct skl_ddb_entry *alloc = &cstate->wm.skl.ddb; - struct skl_plane_wm *wm; u16 alloc_size, start = 0; u16 total[I915_MAX_PLANES] = {}; u16 uv_total[I915_MAX_PLANES] = {}; @@ -4401,7 +4400,8 @@ skl_allocate_pipe_ddb(struct intel_crtc_state *cstate, for (level = ilk_wm_max_level(dev_priv); level >= 0; level--) { blocks = 0; for_each_plane_id_on_crtc(intel_crtc, plane_id) { - wm = &cstate->wm.skl.optimal.planes[plane_id]; + const struct skl_plane_wm *wm = + &cstate->wm.skl.optimal.planes[plane_id]; if (plane_id == PLANE_CURSOR) { if (WARN_ON(wm->wm[level].min_ddb_alloc > @@ -4435,6 +4435,8 @@ skl_allocate_pipe_ddb(struct intel_crtc_state *cstate, * proportional to its relative data rate. */ for_each_plane_id_on_crtc(intel_crtc, plane_id) { + const struct skl_plane_wm *wm = + &cstate->wm.skl.optimal.planes[plane_id]; u64 rate; u16 extra; @@ -4448,8 +4450,6 @@ skl_allocate_pipe_ddb(struct intel_crtc_state *cstate, if (total_data_rate == 0) break; - wm = &cstate->wm.skl.optimal.planes[plane_id]; - rate = plane_data_rate[plane_id]; extra = min_t(u16, alloc_size, DIV64_U64_ROUND_UP(alloc_size * rate, @@ -4474,14 +4474,14 @@ skl_allocate_pipe_ddb(struct intel_crtc_state *cstate, /* Set the actual DDB start/end points for each plane */ start = alloc->start; for_each_plane_id_on_crtc(intel_crtc, plane_id) { - struct skl_ddb_entry *plane_alloc, *uv_plane_alloc; + struct skl_ddb_entry *plane_alloc = + &cstate->wm.skl.plane_ddb_y[plane_id]; + struct skl_ddb_entry *uv_plane_alloc = + &cstate->wm.skl.plane_ddb_uv[plane_id]; if (plane_id == PLANE_CURSOR) continue; - plane_alloc = &cstate->wm.skl.plane_ddb_y[plane_id]; - uv_plane_alloc = &cstate->wm.skl.plane_ddb_uv[plane_id]; - /* Gen11+ uses a separate plane for UV watermarks */ WARN_ON(INTEL_GEN(dev_priv) >= 11 && uv_total[plane_id]); @@ -4507,7 +4507,8 @@ skl_allocate_pipe_ddb(struct intel_crtc_state *cstate, */ for (level++; level <= ilk_wm_max_level(dev_priv); level++) { for_each_plane_id_on_crtc(intel_crtc, plane_id) { - wm = &cstate->wm.skl.optimal.planes[plane_id]; + struct skl_plane_wm *wm = + &cstate->wm.skl.optimal.planes[plane_id]; /* * We only disable the watermarks for each plane if @@ -4543,7 +4544,9 @@ skl_allocate_pipe_ddb(struct intel_crtc_state *cstate, * don't have enough DDB blocks for it. */ for_each_plane_id_on_crtc(intel_crtc, plane_id) { - wm = &cstate->wm.skl.optimal.planes[plane_id]; + struct skl_plane_wm *wm = + &cstate->wm.skl.optimal.planes[plane_id]; + if (wm->trans_wm.plane_res_b >= total[plane_id]) memset(&wm->trans_wm, 0, sizeof(wm->trans_wm)); } -- 2.7.4
