From 166774a2c2c6b82da5d984f587567071ff00c1f3 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Thu, 10 Sep 2020 13:12:25 +0200 Subject: [PATCH] drm/i915: Fix slightly botched merge in __reloc_entry_gpu This function should be an int, not a bool. Presumably because we had the same 2 reverts in a slightly different way, git got confused. Thanks to Dan for reporting. :) The conflict is between the 3 reverts in drm-fixes: 4993a8a37808 ("Revert "drm/i915: Remove i915_gem_object_get_dirty_page()"") ad5d95e4d538 ("Revert "drm/i915/gem: Async GPU relocations only"") 20561da3a2e1 ("Revert "drm/i915/gem: Delete unused code"") And the slightly different combined revert in drm-intel-gt-next, but with the same goal: 102a0a9051f4 ("Revert "drm/i915/gem: Async GPU relocations only"") In the merge commit 1f4b2aca794f ("Merge tag 'drm-intel-gt-next-2020-09-07' of git://anongit.freedesktop.org/drm/drm-intel into drm-next") things went wrong, but the merge commit view now doesn't show any conflict anymore (as git tends to do when the resolution picks one or the other branch). The need to handle other than just true/false error codes in __reloc_entry_gpu was added in the dma_resv locking changes in c43ce12328df ("drm/i915: Use per object locking in execbuf, v12.")

Also note that this was merged before full intel-gfx-CI results, only after BAT, since the breakage at the BAT run is already severe enough to block all pre-merge testing.] Fixes: 1f4b2aca794f ("Merge tag 'drm-intel-gt-next-2020-09-07' of git://anongit.freedesktop.org/drm/drm-intel into drm-next") Acked-by: Joonas Lahtinen Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20200910111225.2184193-1-maarten.lankhorst@linux.intel.com --- drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c b/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c index 804339255df19..5509946f1a1da 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c @@ -1437,7 +1437,7 @@ static unsigned long vma_phys_addr(struct i915_vma *vma, u32 offset) return addr + offset_in_page(offset); } -static bool __reloc_entry_gpu(struct i915_execbuffer *eb, +static int __reloc_entry_gpu(struct i915_execbuffer *eb, struct i915_vma *vma, u64 offset, u64 target_addr) @@ -1456,7 +1456,7 @@ static bool __reloc_entry_gpu(struct i915_execbuffer *eb, batch = reloc_gpu(eb, vma, len); if (batch == ERR_PTR(-EDEADLK)) - return (s64)-EDEADLK; + return -EDEADLK; else if (IS_ERR(batch)) return false; -- 2.39.5
