From: Mika Kuoppala Date: Thu, 25 Jun 2015 15:35:08 +0000 (+0300) Subject: drm/i915/gtt: Rename unmap_and_free_px to free_px X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a08e111a6cc88514155b087e0c307581064352b5;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git drm/i915/gtt: Rename unmap_and_free_px to free_px All the paging structures are now similar and mapped for dma. The unmapping is taken care of by common accessors, so don't overload the reader with such details. v2: Be consistent with goto labels (Michel) Signed-off-by: Mika Kuoppala Reviewed-by: Michel Thierry Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_gem_gtt.c b/drivers/gpu/drm/i915/i915_gem_gtt.c index a7bdbeb46904..82ccc69a4a23 100644 --- a/drivers/gpu/drm/i915/i915_gem_gtt.c +++ b/drivers/gpu/drm/i915/i915_gem_gtt.c @@ -330,8 +330,7 @@ static void cleanup_page_dma(struct drm_device *dev, struct i915_page_dma *p) memset(p, 0, sizeof(*p)); } -static void unmap_and_free_pt(struct i915_page_table *pt, - struct drm_device *dev) +static void free_pt(struct drm_device *dev, struct i915_page_table *pt) { cleanup_page_dma(dev, &pt->base); kfree(pt->used_ptes); @@ -387,8 +386,7 @@ fail_bitmap: return ERR_PTR(ret); } -static void unmap_and_free_pd(struct i915_page_directory *pd, - struct drm_device *dev) +static void free_pd(struct drm_device *dev, struct i915_page_directory *pd) { if (pd->base.page) { cleanup_page_dma(dev, &pd->base); @@ -409,17 +407,17 @@ static struct i915_page_directory *alloc_pd(struct drm_device *dev) pd->used_pdes = kcalloc(BITS_TO_LONGS(I915_PDES), sizeof(*pd->used_pdes), GFP_KERNEL); if (!pd->used_pdes) - goto free_pd; + goto fail_bitmap; ret = setup_page_dma(dev, &pd->base); if (ret) - goto free_bitmap; + goto fail_page_m; return pd; -free_bitmap: +fail_page_m: kfree(pd->used_pdes); -free_pd: +fail_bitmap: kfree(pd); return ERR_PTR(ret); @@ -615,7 +613,7 @@ static void gen8_free_page_tables(struct i915_page_directory *pd, struct drm_dev if (WARN_ON(!pd->page_table[i])) continue; - unmap_and_free_pt(pd->page_table[i], dev); + free_pt(dev, pd->page_table[i]); pd->page_table[i] = NULL; } } @@ -631,11 +629,11 @@ static void gen8_ppgtt_cleanup(struct i915_address_space *vm) continue; gen8_free_page_tables(ppgtt->pdp.page_directory[i], ppgtt->base.dev); - unmap_and_free_pd(ppgtt->pdp.page_directory[i], ppgtt->base.dev); + free_pd(ppgtt->base.dev, ppgtt->pdp.page_directory[i]); } - unmap_and_free_pd(ppgtt->scratch_pd, ppgtt->base.dev); - unmap_and_free_pt(ppgtt->scratch_pt, ppgtt->base.dev); + free_pd(ppgtt->base.dev, ppgtt->scratch_pd); + free_pt(ppgtt->base.dev, ppgtt->scratch_pt); } /** @@ -688,7 +686,7 @@ static int gen8_ppgtt_alloc_pagetabs(struct i915_hw_ppgtt *ppgtt, unwind_out: for_each_set_bit(pde, new_pts, I915_PDES) - unmap_and_free_pt(pd->page_table[pde], dev); + free_pt(dev, pd->page_table[pde]); return -ENOMEM; } @@ -746,7 +744,7 @@ static int gen8_ppgtt_alloc_page_directories(struct i915_hw_ppgtt *ppgtt, unwind_out: for_each_set_bit(pdpe, new_pds, GEN8_LEGACY_PDPES) - unmap_and_free_pd(pdp->page_directory[pdpe], dev); + free_pd(dev, pdp->page_directory[pdpe]); return -ENOMEM; } @@ -904,11 +902,11 @@ static int gen8_alloc_va_range(struct i915_address_space *vm, err_out: while (pdpe--) { for_each_set_bit(temp, new_page_tables[pdpe], I915_PDES) - unmap_and_free_pt(ppgtt->pdp.page_directory[pdpe]->page_table[temp], vm->dev); + free_pt(vm->dev, ppgtt->pdp.page_directory[pdpe]->page_table[temp]); } for_each_set_bit(pdpe, new_page_dirs, GEN8_LEGACY_PDPES) - unmap_and_free_pd(ppgtt->pdp.page_directory[pdpe], vm->dev); + free_pd(vm->dev, ppgtt->pdp.page_directory[pdpe]); free_gen8_temp_bitmaps(new_page_dirs, new_page_tables); mark_tlbs_dirty(ppgtt); @@ -1358,7 +1356,7 @@ unwind_out: struct i915_page_table *pt = ppgtt->pd.page_table[pde]; ppgtt->pd.page_table[pde] = ppgtt->scratch_pt; - unmap_and_free_pt(pt, vm->dev); + free_pt(vm->dev, pt); } mark_tlbs_dirty(ppgtt); @@ -1377,11 +1375,11 @@ static void gen6_ppgtt_cleanup(struct i915_address_space *vm) gen6_for_all_pdes(pt, ppgtt, pde) { if (pt != ppgtt->scratch_pt) - unmap_and_free_pt(pt, ppgtt->base.dev); + free_pt(ppgtt->base.dev, pt); } - unmap_and_free_pt(ppgtt->scratch_pt, ppgtt->base.dev); - unmap_and_free_pd(&ppgtt->pd, ppgtt->base.dev); + free_pt(ppgtt->base.dev, ppgtt->scratch_pt); + free_pd(ppgtt->base.dev, &ppgtt->pd); } static int gen6_ppgtt_allocate_page_directories(struct i915_hw_ppgtt *ppgtt) @@ -1431,7 +1429,7 @@ alloc: return 0; err_out: - unmap_and_free_pt(ppgtt->scratch_pt, ppgtt->base.dev); + free_pt(ppgtt->base.dev, ppgtt->scratch_pt); return ret; }
