From 210a0f5ce46080e6728e54010d50317fc9e1d969 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 27 Jul 2021 14:10:34 +0200 Subject: [PATCH] drm/i915: move scheduler slabs 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_dependencies|priorities to just a slab_dependencies|priorities. 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/20210727121037.2041102-8-daniel.vetter@ffwll.ch --- drivers/gpu/drm/i915/i915_globals.c | 2 -- drivers/gpu/drm/i915/i915_globals.h | 2 -- drivers/gpu/drm/i915/i915_pci.c | 2 ++ drivers/gpu/drm/i915/i915_scheduler.c | 39 +++++++++++---------------- drivers/gpu/drm/i915/i915_scheduler.h | 3 +++ 5 files changed, 20 insertions(+), 28 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_globals.c b/drivers/gpu/drm/i915/i915_globals.c index 8fffa8d93bc58..8923589057ab7 100644 --- a/drivers/gpu/drm/i915/i915_globals.c +++ b/drivers/gpu/drm/i915/i915_globals.c @@ -8,7 +8,6 @@ #include #include "i915_globals.h" -#include "i915_scheduler.h" #include "i915_vma.h" static LIST_HEAD(globals);
