From a28beb344bb1f02b1306ce3ceaecbf2afe3e42cd Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 27 Jul 2021 14:10:29 +0200 Subject: [PATCH] drm/i915: move i915_buddy slab to direct module init/exit With the global kmem_cache shrink infrastructure gone there's nothing special and we can convert them over. I'm doing this split up into each patch because there's quite a bit of noise with removing the static global.slab_blocks to just a slab_blocks. v2: Make slab static (Jason, 0day) Reviewed-by: Jason Ekstrand Cc: Jason Ekstrand Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20210727121037.2041102-3-daniel.vetter@ffwll.ch --- drivers/gpu/drm/i915/i915_buddy.c | 25 ++++++++----------------- drivers/gpu/drm/i915/i915_buddy.h | 3 ++- drivers/gpu/drm/i915/i915_globals.c | 2 -- drivers/gpu/drm/i915/i915_pci.c | 2 ++ 4 files changed, 12 insertions(+), 20 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_buddy.c b/drivers/gpu/drm/i915/i915_buddy.c index caabcaea3be7..7b274c51cac0 100644 --- a/drivers/gpu/drm/i915/i915_buddy.c +++ b/drivers/gpu/drm/i915/i915_buddy.c @@ -8,13 +8,9 @@ #include "i915_buddy.h" #include "i915_gem.h" -#include "i915_globals.h" #include "i915_utils.h" -static struct i915_global_buddy { - struct i915_global base; - struct kmem_cache *slab_blocks; -} global; +static struct kmem_cache *slab_blocks; static struct i915_buddy_block *i915_block_alloc(struct i915_buddy_mm *mm, struct i915_buddy_block *parent, @@ -25,7 +21,7 @@ static struct i915_buddy_block *i915_block_alloc(struct i915_buddy_mm *mm, GEM_BUG_ON(order > I915_BUDDY_MAX_ORDER); - block = kmem_cache_zalloc(global.slab_blocks, GFP_KERNEL); + block = kmem_cache_zalloc(slab_blocks, GFP_KERNEL); if (!block) return NULL; @@ -40,7 +36,7 @@ static struct i915_buddy_block *i915_block_alloc(struct i915_buddy_mm *mm, static void i915_block_free(struct i915_buddy_mm *mm, struct i915_buddy_block *block) { - kmem_cache_free(global.slab_blocks, block); + kmem_cache_free(slab_blocks, block); } static void mark_allocated(struct i915_buddy_block *block) @@ -410,21 +406,16 @@ int i915_buddy_alloc_range(struct i915_buddy_mm *mm, #include "selftests/i915_buddy.c" #endif -static void i915_global_buddy_exit(void) +void i915_buddy_module_exit(void) { - kmem_cache_destroy(global.slab_blocks); + kmem_cache_destroy(slab_blocks); } -static struct i915_global_buddy global = { { - .exit = i915_global_buddy_exit, -} }; - -int __init i915_global_buddy_init(void) +int __init i915_buddy_module_init(void) { - global.slab_blocks = KMEM_CACHE(i915_buddy_block, 0); - if (!global.slab_blocks) + slab_blocks = KMEM_CACHE(i915_buddy_block, 0); + if (!slab_blocks) return -ENOMEM; - i915_global_register(&global.base); return 0; } diff --git a/drivers/gpu/drm/i915/i915_buddy.h b/drivers/gpu/drm/i915/i915_buddy.h index d8f26706de52..3940d632f208 100644 --- a/drivers/gpu/drm/i915/i915_buddy.h +++ b/drivers/gpu/drm/i915/i915_buddy.h @@ -129,6 +129,7 @@ void i915_buddy_free(struct i915_buddy_mm *mm, struct i915_buddy_block *block); void i915_buddy_free_list(struct i915_buddy_mm *mm, struct list_head *objects); -int i915_global_buddy_init(void); +void i915_buddy_module_exit(void); +int i915_buddy_module_init(void); #endif diff --git a/drivers/gpu/drm/i915/i915_globals.c b/drivers/gpu/drm/i915/i915_globals.c index a53135ee831d..3de7cf22ec76 100644 --- a/drivers/gpu/drm/i915/i915_globals.c +++ b/drivers/gpu/drm/i915/i915_globals.c @@ -7,7 +7,6 @@ #include #include -#include "i915_buddy.h" #include "gem/i915_gem_context.h" #include "gem/i915_gem_object.h" #include "i915_globals.h" @@ -33,7 +32,6 @@ static void __i915_globals_cleanup(void) } static __initconst int (* const initfn[])(void) = { - i915_global_buddy_init, i915_global_context_init, i915_global_gem_context_init, i915_global_objects_init, diff --git a/drivers/gpu/drm/i915/i915_pci.c b/drivers/gpu/drm/i915/i915_pci.c index 930dd93de7b0..ddc4ba1cd421 100644 --- a/drivers/gpu/drm/i915/i915_pci.c +++ b/drivers/gpu/drm/i915/i915_pci.c @@ -31,6 +31,7 @@ #include "display/intel_fbdev.h" #include "i915_active.h" +#include "i915_buddy.h" #include "i915_drv.h" #include "i915_perf.h" #include "i915_globals.h" @@ -1261,6 +1262,7 @@ static const struct { } init_funcs[] = { { i915_check_nomodeset, NULL }, { i915_active_module_init, i915_active_module_exit }, + { i915_buddy_module_init, i915_buddy_module_exit }, { i915_globals_init, i915_globals_exit }, { i915_mock_selftests, NULL }, { i915_pmu_init, i915_pmu_exit },
