[PATCH v2] drm/nouveau: fix incorrect conversion to dma_resv_wait_timeout()
Commit 41d351f29528 ("drm/nouveau: stop using ttm_bo_wait")
converted from ttm_bo_wait_ctx() to dma_resv_wait_timeout().
However, dma_resv_wait_timeout() returns greater than zero on
success as opposed to ttm_bo_wait_ctx(). As a result, relocs
will fail and log errors even when it was a success.
Change the return code handling to match that of
nouveau_gem_ioctl_cpu_prep(), which was alr...

[PATCH drm-misc-next 0/3] [RFC] DRM GPUVA Manager GPU-VM features
So far the DRM GPUVA manager offers common infrastructure to track GPU VA
allocations and mappings, generically connect GPU VA mappings to their
backing buffers and perform more complex mapping operations on the GPU VA
space.
However, there are more design patterns commonly used by drivers, which
can potentially be generalized in order to make the DRM GPUVA manager
represent a basic GPU-VM
