mmap locking API: use coccinelle to convert mmap_sem rwsem call sites

2020-06-09T16:39:14Z

This change converts the existing mmap_sem rwsem calls to use the new mmap locking API instead. The change is generated using coccinelle with the following rule: // spatch --sp-file mmap_lock_api.cocci --in-place --include-headers --dir . @@ expression mm; @@ ( -init_rwsem +mmap_init_lock | -down_write +mmap_write_lock | -down_write_killable +mmap_write_lock_killable | -down_write_trylock +mmap_write_trylock | -up_write +mmap_write_unlock | -downgrade_write +mmap_write_downgrade | -down_read +mmap_read_lock | -down_read_killable +mmap_read_lock_killable | -down_read_trylock +mmap_read_trylock | -up_read +mmap_read_unlock ) -(&mm->mmap_sem) +(mm) Signed-off-by: Michel Lespinasse Signed-off-by: Andrew Morton Reviewed-by: Daniel Jordan Reviewed-by: Laurent Dufour Reviewed-by: Vlastimil Babka Cc: Davidlohr Bueso Cc: David Rientjes Cc: Hugh Dickins Cc: Jason Gunthorpe Cc: Jerome Glisse Cc: John Hubbard Cc: Liam Howlett Cc: Matthew Wilcox Cc: Peter Zijlstra Cc: Ying Han Link: http://lkml.kernel.org/r/20200520052908.204642-5-walken@google.com Signed-off-by: Linus Torvalds

drm/amdkfd: fix restore worker race condition

2020-05-21T21:59:45Z

In free memory of gpu path, remove bo from validate_list to make sure restore worker don't access the BO any more, then unregister bo MMU interval notifier. Otherwise, the restore worker will crash in the middle of validating BO user pages if MMU interval notifer is gone. Signed-off-by: Philip Yang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Use GEM obj reference for KFD BOs

2020-05-06T20:51:29Z

Releasing the AMDGPU BO ref directly leads to problems when BOs were exported as DMA bufs. Releasing the GEM reference makes sure that the AMDGPU/TTM BO is not freed too early. Also take a GEM reference when importing BOs from DMABufs to keep references to imported BOs balances properly.

drm/amdkfd: Consolidate duplicated bo alloc flags

2020-03-10T19:54:34Z

ALLOC_MEM_FLAGS_* used are the same as the KFD_IOC_ALLOC_MEM_FLAGS_*, but they are interweavedly used in kernel driver, resulting in bad readability. For example, KFD_IOC_ALLOC_MEM_FLAGS_COHERENT is not referenced in kernel, and it functions implicitly in kernel through ALLOC_MEM_FLAGS_COHERENT, causing unnecessary confusion. Replace all occurrences of ALLOC_MEM_FLAGS_* with KFD_IOC_ALLOC_MEM_FLAGS_* to solve the problem. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Remove kfd eviction fence before release bo (v2)

2020-02-26T19:17:32Z

No need to trigger eviction as the memory mapping will not be used anymore. All pt/pd bos share same resv, hence the same shared eviction fence. Everytime page table is freed, the fence will be signled and that cuases kfd unexcepted evictions. v2: squash in 32 bit fix CC: Christian König CC: Felix Kuehling CC: Alex Deucher Acked-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: xinhui pan Signed-off-by: Alex Deucher
