From 62027b7736d038309e93e6d5d25a9a72390821cb Mon Sep 17 00:00:00 2001 From: Mahesh Kumar Date: Mon, 9 Apr 2018 09:11:05 +0530 Subject: [PATCH] drm/i915/skl+: pass skl_wm_level struct to wm compute func This patch passes skl_wm_level structure itself to watermark computation function skl_compute_plane_wm function (instead of its internal parameters). It reduces number of arguments required to be passed. v2: Addressed review comments by Shashank Sharma v3: Adding reviewed by tag from Shashank Sharma v4: Added reviewed by from Juha-Pekka Heikkila v5: Rebased the series Reviewed-by: Juha-Pekka Heikkila Reviewed-by: Shashank Sharma Signed-off-by: Mahesh Kumar Signed-off-by: Vidya Srinivas Reviewed-by: Maarten Lankhorst Signed-off-by: Maarten Lankhorst Link: https://patchwork.freedesktop.org/patch/msgid/1523245273-30264-7-git-send-email-vidya.srinivas@intel.com --- drivers/gpu/drm/i915/intel_pm.c | 18 +++++++----------- 1 file changed, 7 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c index fb30efa22c24..06352c9e9ef6 100644 --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -4529,9 +4529,7 @@ static int skl_compute_plane_wm(const struct drm_i915_private *dev_priv, uint16_t ddb_allocation, int level, const struct skl_wm_params *wp, - uint16_t *out_blocks, /* out */ - uint8_t *out_lines, /* out */ - bool *enabled /* out */) + struct skl_wm_level *result /* out */) { const struct drm_plane_state *pstate = &intel_pstate->base; uint32_t latency = dev_priv->wm.skl_latency[level]; @@ -4545,7 +4543,7 @@ static int skl_compute_plane_wm(const struct drm_i915_private *dev_priv, if (latency == 0 || !intel_wm_plane_visible(cstate, intel_pstate)) { - *enabled = false; + result->plane_en = false; return 0; } @@ -4626,7 +4624,7 @@ static int skl_compute_plane_wm(const struct drm_i915_private *dev_priv, if ((level > 0 && res_lines > 31) || res_blocks >= ddb_allocation || min_disp_buf_needed >= ddb_allocation) { - *enabled = false; + result->plane_en = false; /* * If there are no valid level 0 watermarks, then we can't @@ -4646,9 +4644,9 @@ static int skl_compute_plane_wm(const struct drm_i915_private *dev_priv, } /* The number of lines are ignored for the level 0 watermark. */ - *out_lines = level ? res_lines : 0; - *out_blocks = res_blocks; - *enabled = true; + result->plane_res_b = res_blocks; + result->plane_res_l = res_lines; + result->plane_en = true; return 0; } @@ -4688,9 +4686,7 @@ skl_compute_wm_levels(const struct drm_i915_private *dev_priv, ddb_blocks, level, wm_params, - &result->plane_res_b, - &result->plane_res_l, - &result->plane_en); + result); if (ret) return ret; } -- 2.11.0
