From: Mika Kuoppala Date: Thu, 25 Jun 2015 15:35:17 +0000 (+0300) Subject: drm/i915/gtt: Move scratch_pd and scratch_pt into vm struct X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=79ab93705464982b9f7e9b5dfabfacde634338aa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915/gtt: Move scratch_pd and scratch_pt into vm struct Scratch page is part of struct i915_address_space. Move other scratch entities into the same struct. This is a preparatory patch for having only one instance of each scratch_pt/pd. v2: make commit msg more readable Signed-off-by: Mika Kuoppala Reviewed-by: Michel Thierry (v1) [danvet: Bikeshed summary to avoid confusion with vmas.] 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 6817b072fac4..2c8201e06e27 100644 --- a/drivers/gpu/drm/i915/i915_gem_gtt.c +++ b/drivers/gpu/drm/i915/i915_gem_gtt.c @@ -612,12 +612,9 @@ static void gen8_ppgtt_insert_entries(struct i915_address_space *vm, static void gen8_initialize_pd(struct i915_address_space *vm, struct i915_page_directory *pd) { - struct i915_hw_ppgtt *ppgtt = - container_of(vm, struct i915_hw_ppgtt, base); gen8_pde_t scratch_pde; - scratch_pde = gen8_pde_encode(px_dma(ppgtt->scratch_pt), - I915_CACHE_LLC); + scratch_pde = gen8_pde_encode(px_dma(vm->scratch_pt), I915_CACHE_LLC); fill_px(vm->dev, pd, scratch_pde); } @@ -652,8 +649,8 @@ static void gen8_ppgtt_cleanup(struct i915_address_space *vm) free_pd(ppgtt->base.dev, ppgtt->pdp.page_directory[i]); } - free_pd(ppgtt->base.dev, ppgtt->scratch_pd); - free_pt(ppgtt->base.dev, ppgtt->scratch_pt); + free_pd(vm->dev, vm->scratch_pd); + free_pt(vm->dev, vm->scratch_pt); } /** @@ -689,7 +686,7 @@ static int gen8_ppgtt_alloc_pagetabs(struct i915_hw_ppgtt *ppgtt, /* Don't reallocate page tables */ if (pt) { /* Scratch is never allocated this way */ - WARN_ON(pt == ppgtt->scratch_pt); + WARN_ON(pt == ppgtt->base.scratch_pt); continue; } @@ -940,16 +937,16 @@ err_out: */ static int gen8_ppgtt_init(struct i915_hw_ppgtt *ppgtt) { - ppgtt->scratch_pt = alloc_pt(ppgtt->base.dev); - if (IS_ERR(ppgtt->scratch_pt)) - return PTR_ERR(ppgtt->scratch_pt); + ppgtt->base.scratch_pt = alloc_pt(ppgtt->base.dev); + if (IS_ERR(ppgtt->base.scratch_pt)) + return PTR_ERR(ppgtt->base.scratch_pt); - ppgtt->scratch_pd = alloc_pd(ppgtt->base.dev); - if (IS_ERR(ppgtt->scratch_pd)) - return PTR_ERR(ppgtt->scratch_pd); + ppgtt->base.scratch_pd = alloc_pd(ppgtt->base.dev); + if (IS_ERR(ppgtt->base.scratch_pd)) + return PTR_ERR(ppgtt->base.scratch_pd); - gen8_initialize_pt(&ppgtt->base, ppgtt->scratch_pt); - gen8_initialize_pd(&ppgtt->base, ppgtt->scratch_pd); + gen8_initialize_pt(&ppgtt->base, ppgtt->base.scratch_pt); + gen8_initialize_pd(&ppgtt->base, ppgtt->base.scratch_pd); ppgtt->base.start = 0; ppgtt->base.total = 1ULL << 32; @@ -981,7 +978,8 @@ static void gen6_dump_ppgtt(struct i915_hw_ppgtt *ppgtt, struct seq_file *m) uint32_t pte, pde, temp; uint32_t start = ppgtt->base.start, length = ppgtt->base.total; - scratch_pte = vm->pte_encode(px_dma(vm->scratch_page), I915_CACHE_LLC, true, 0); + scratch_pte = vm->pte_encode(px_dma(vm->scratch_page), + I915_CACHE_LLC, true, 0); gen6_for_each_pde(unused, &ppgtt->pd, start, length, temp, pde) { u32 expected; @@ -1314,7 +1312,7 @@ static int gen6_alloc_va_range(struct i915_address_space *vm, * tables. */ gen6_for_each_pde(pt, &ppgtt->pd, start, length, temp, pde) { - if (pt != ppgtt->scratch_pt) { + if (pt != vm->scratch_pt) { WARN_ON(bitmap_empty(pt->used_ptes, GEN6_PTES)); continue; } @@ -1369,7 +1367,7 @@ unwind_out: for_each_set_bit(pde, new_page_tables, I915_PDES) { struct i915_page_table *pt = ppgtt->pd.page_table[pde]; - ppgtt->pd.page_table[pde] = ppgtt->scratch_pt; + ppgtt->pd.page_table[pde] = vm->scratch_pt; free_pt(vm->dev, pt); } @@ -1384,15 +1382,14 @@ static void gen6_ppgtt_cleanup(struct i915_address_space *vm) struct i915_page_table *pt; uint32_t pde; - drm_mm_remove_node(&ppgtt->node); gen6_for_all_pdes(pt, ppgtt, pde) { - if (pt != ppgtt->scratch_pt) + if (pt != vm->scratch_pt) free_pt(ppgtt->base.dev, pt); } - free_pt(ppgtt->base.dev, ppgtt->scratch_pt); + free_pt(vm->dev, vm->scratch_pt); } static int gen6_ppgtt_allocate_page_directories(struct i915_hw_ppgtt *ppgtt) @@ -1407,11 +1404,11 @@ static int gen6_ppgtt_allocate_page_directories(struct i915_hw_ppgtt *ppgtt) * size.
