drm/ttm: use the same attributes when freeing d_page->vaddr

2019-07-18T19:17:18+00:00

In function __ttm_dma_alloc_page(), d_page->addr is allocated by dma_alloc_attrs() but freed with use dma_free_coherent() in __ttm_dma_free_page(). Use the correct dma_free_attrs() to free d_page->vaddr. Signed-off-by: Fuqian Huang Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/ttm: return -EBUSY if waiting for busy BO fails

2019-06-27T16:19:36+00:00

Returning -EAGAIN prevents ttm_bo_mem_space from trying alternate placements and can lead to live-locks in amdgpu_cs, retrying indefinitely and never succeeding.

drm: Permit video-buffers writecombine mapping for MIPS

2019-06-18T19:41:33+00:00

Since commit 4b050ba7a66c ("MIPS: pgtable.h: Implement the pgprot_writecombine function for MIPS") and commit c4687b15a848 ("MIPS: Fix definition of pgprot_writecombine()") write-combine vma mapping is available to be used by kernel subsystems for MIPS. In particular the uncached accelerated attribute is requested to be set by ioremap_wc() method and by generic PCI memory pages/ranges mapping methods. The same is done by the drm_io_prot()/ttm_io_prot() functions in case if write-combine flag is set for vma's passed for mapping. But for some reason the pgprot_writecombine() method calling is ifdefed to be a platform-specific with MIPS system being marked as lacking of one. At the very least it doesn't reflect the current MIPS platform implementation. So in order to improve the DRM subsystem performance on MIPS with UCA mapping enabled, we need to have pgprot_writecombine() called for buffers, which need store operations being combined. In case if particular MIPS chip doesn't support the UCA attribute, the mapping will fall back to noncached.

drm/ttm: TTM fault handler helpers

2019-06-18T13:19:34+00:00

With the vmwgfx dirty tracking, the default TTM fault handler is not completely sufficient (vmwgfx need to modify the vma->vm_flags member, and also needs to restrict the number of prefaults). We also want to replicate the new ttm_bo_vm_reserve() functionality So start turning the TTM vm code into helpers: ttm_bo_vm_fault_reserved() and ttm_bo_vm_reserve(), and provide a default TTM fault handler for other drivers to use.

drm/ttm: Allow the driver to provide the ttm struct vm_operations_struct

2019-06-18T13:19:34+00:00

Add a pointer to the struct vm_operations_struct in the bo_device, and assign that pointer to the default value currently used. The driver can then optionally modify that pointer and the new value can be used for each new vma created. Cc: "Christian König" Signed-off-by: Thomas Hellstrom Reviewed-by: Christian König

drm/ttm: fix busy memory to fail other user v10

2019-05-31T15:39:34+00:00

BOs on the LRU might be blocked during command submission and cause OOM situations. Avoid this by blocking for the first busy BO not locked by the same ticket as the BO we are searching space for. v10: completely start over with the patch since we didn't handled a whole bunch of corner cases.

2019-05-31T15:39:34+00:00

Move BOs which are currently in a lower domain to the new LRU before allocating backing space while validating. This makes sure that we always have enough entries on the LRU to allow for other processes to wait for an operation to complete. v2: generalize the test v3: fix rebase error Signed-off-by: Christian König Reviewed-by: Chunming Zhou Tested-by: Pierre-Eric Pelloux-Prayer Signed-off-by: Alex Deucher
