5.19 fixes for msm-next - Limiting WB modes to max sspp linewidth - Fixing the supported rotations to add 180 back for IGT - Fix to handle pm_runtime_get_sync() errors to avoid unclocked access in the bind() path for dpu driver - Fix the irq_free() without request issue which was a big-time hitter in the CI-runs.

drm/msm/a6xx: Fix refcount leak in a6xx_gpu_init

2022-05-18T17:54:39Z

of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. a6xx_gmu_init() passes the node to of_find_device_by_node() and of_dma_configure(), of_find_device_by_node() will takes its reference, of_dma_configure() doesn't need the node after usage. Add missing of_node_put() to avoid refcount leak.

drm/msm: Fix null pointer dereferences without iommu

2022-05-02T17:11:44Z

drm/msm: Add a way for userspace to allocate GPU iova

2022-04-21T22:03:12Z

The motivation at this point is mainly native userspace mesa driver in a VM guest. The one remaining synchronous "hotpath" is buffer allocation, because guest needs to wait to know the bo's iova before it can start emitting cmdstream/state that references the new bo. By allocating the iova in the guest userspace, we no longer need to wait for a response from the host, but can just rely on the allocation request being processed before the cmdstream submission. Allocation failures (OoM, etc) would just be treated as context-lost (ie. GL_GUILTY_CONTEXT_RESET) or subsequent allocations (or readpix, etc) can raise GL_OUT_OF_MEMORY. v2: Fix inuse check v3: Change mismatched iova case to -EBUSY Signed-off-by: Rob Clark Reviewed-by: Dmitry Baryshkov Reviewed-by: Dmitry Osipenko Link: https://lore.kernel.org/r/20220411215849.297838-11-robdclark@gmail.com Signed-off-by: Rob Clark

drm/msm/gpu: Drop duplicate fence counter

2022-04-21T22:03:11Z

The ring seqno counter duplicates the fence-context last_fence counter. They end up getting incremented in lock-step, on the same scheduler thread, but the split just makes things less obvious.

drm/msm: Add a way to override processes comm/cmdline

2022-04-21T22:01:09Z

In the cause of using the GPU via virtgpu, the host side process is really a sort of proxy, and not terribly interesting from the PoV of crash/fault logging. Add a way to override these per process so that we can see the guest process's name. v2: Handle kmalloc failure, add comment to explain kstrdup returns NULL if passed NULL [Dan Carpenter] Signed-off-by: Rob Clark Link: https://lore.kernel.org/r/20220317165144.222101-4-robdclark@gmail.com Signed-off-by: Rob Clark
