From 53b725c7db127d16d1a83ed5dfd601d65fe976fb Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Mon, 5 Mar 2018 14:21:21 -0800 Subject: [PATCH] drm/i915/error: standardize function style in error capture some of the static functions used from capture() have the "i915_" prefix while other don't; most of them take i915 as a parameter, but one of them derives it internally from error->i915. Let's be consistent by avoiding prefix for static functions and by getting i915 from error->i915. While at it, s/dev_priv/i915 in functions that don't perform register reads. v2: take i915 from error->i915 (Michal), s/dev_priv/i915, update commit message Cc: Michal Wajdeczko Cc: Chris Wilson Signed-off-by: Daniele Ceraolo Spurio Reviewed-by: Michel Thierry Reviewed-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20180305222122.3547-2-daniele.ceraolospurio@intel.com Signed-off-by: Chris Wilson --- drivers/gpu/drm/i915/i915_gpu_error.c | 84 +++++++++++++-------------- 1 file changed, 39 insertions(+), 45 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gpu_error.c b/drivers/gpu/drm/i915/i915_gpu_error.c index ef29fb48d6d9..9afb1b9674c0 100644 --- a/drivers/gpu/drm/i915/i915_gpu_error.c +++ b/drivers/gpu/drm/i915/i915_gpu_error.c @@ -1084,9 +1084,9 @@ static uint32_t i915_error_generate_code(struct drm_i915_private *dev_priv, return error_code; } -static void i915_gem_record_fences(struct drm_i915_private *dev_priv, - struct i915_gpu_state *error) +static void gem_record_fences(struct i915_gpu_state *error) { + struct drm_i915_private *dev_priv = error->i915; int i; if (INTEL_GEN(dev_priv) >= 6) { @@ -1424,14 +1424,14 @@ capture_object(struct drm_i915_private *dev_priv, } } -static void i915_gem_record_rings(struct drm_i915_private *dev_priv, - struct i915_gpu_state *error) +static void gem_record_rings(struct i915_gpu_state *error) { - struct i915_ggtt *ggtt = &dev_priv->ggtt; + struct drm_i915_private *i915 = error->i915; + struct i915_ggtt *ggtt = &i915->ggtt; int i; for (i = 0; i < I915_NUM_ENGINES; i++) { - struct intel_engine_cs *engine = dev_priv->engine[i]; + struct intel_engine_cs *engine = i915->engine[i]; struct drm_i915_error_engine *ee = &error->engine[i]; struct i915_request *request; @@ -1460,17 +1460,16 @@ static void i915_gem_record_rings(struct drm_i915_private *dev_priv, * by userspace. */ ee->batchbuffer = - i915_error_object_create(dev_priv, - request->batch); + i915_error_object_create(i915, request->batch); - if (HAS_BROKEN_CS_TLB(dev_priv)) + if (HAS_BROKEN_CS_TLB(i915)) ee->wa_batchbuffer = - i915_error_object_create(dev_priv, + i915_error_object_create(i915, engine->scratch); request_record_user_bo(request, ee); ee->ctx = - i915_error_object_create(dev_priv, + i915_error_object_create(i915, request->ctx->engine[i].state); error->simulated |= @@ -1484,27 +1483,24 @@ static void i915_gem_record_rings(struct drm_i915_private *dev_priv, ee->cpu_ring_head = ring->head; ee->cpu_ring_tail = ring->tail; ee->ringbuffer = - i915_error_object_create(dev_priv, ring->vma); + i915_error_object_create(i915, ring->vma); engine_record_requests(engine, request, ee); } ee->hws_page = - i915_error_object_create(dev_priv, + i915_error_object_create(i915, engine->status_page.vma); - ee->wa_ctx = - i915_error_object_create(dev_priv, engine->wa_ctx.vma); + ee->wa_ctx = i915_error_object_create(i915, engine->wa_ctx.vma); - ee->default_state = - capture_object(dev_priv, engine->default_state); + ee->default_state = capture_object(i915, engine->default_state); } } -static void i915_gem_capture_vm(struct drm_i915_private *dev_priv, - struct i915_gpu_state *error, - struct i915_address_space *vm, - int idx) +static void gem_capture_vm(struct i915_gpu_state *error, + struct i915_address_space *vm, + int idx) { struct drm_i915_error_buffer *active_bo; struct i915_vma *vma; @@ -1527,8 +1523,7 @@ static void i915_gem_capture_vm(struct drm_i915_private *dev_priv, error->active_bo_count[idx] = count; } -static void i915_capture_active_buffers(struct drm_i915_private *dev_priv, - struct i915_gpu_state *error) +static void capture_active_buffers(struct i915_gpu_state *error) { int cnt = 0, i, j; @@ -1548,14 +1543,13 @@ static void i915_capture_active_buffers(struct drm_i915_private *dev_priv, for (j = 0; j < i && !found; j++) found = error->engine[j].vm == ee->vm; if (!found) - i915_gem_capture_vm(dev_priv, error, ee->vm, cnt++); + gem_capture_vm(error, ee->vm, cnt++); } } -static void i915_capture_pinned_buffers(struct drm_i915_private *dev_priv, - struct i915_gpu_state *error) +static void capture_pinned_buffers(struct i915_gpu_state *error) { - struct i915_address_space *vm = &dev_priv->ggtt.base; + struct i915_address_space *vm = &error->i915->ggtt.base; struct drm_i915_error_buffer *bo; struct i915_vma *vma; int count_inactive, count_active; @@ -1605,9 +1599,9 @@ static void capture_uc_state(struct i915_gpu_state *error) } /* Capture all registers which don't fit into another category. */ -static void i915_capture_reg_state(struct drm_i915_private *dev_priv, - struct i915_gpu_state *error) +static void capture_reg_state(struct i915_gpu_state *error) { + struct drm_i915_private *dev_priv = error->i915; int i; /* General organization @@ -1704,24 +1698,25 @@ static void i915_error_capture_msg(struct drm_i915_private *dev_priv, engine_mask ?
