On Raven Invalid PPRs (peripheral page requests) can be reported because multiple PPRs can be still queued when memory is freed. Apply a rate limit to avoid flooding the log in this case. Signed-off-by:

If there are several memory banks that has the same properties in CRAT, we aggregate them into one memory bank. This cleans up memory banks on APUs (e.g. Raven) where the CRAT reports each memory channel as a separate bank. This only confuses user mode, which only deals with virtual memory. Signed-off-by:

1. Pre-GFX9 the amdgpu ISR saves the vm-fault status and address per per-vmid. amdkfd needs to get the information from amdgpu through the new get_vm_fault_info interface. On GFX9 and later, all the required information is in the IH ring 2. amdkfd unmaps all queues from the faulting process and create new run-list without the guilty process 3. amdkfd notifies the runtime of the vm fault trap via EVENT_TYPE_MEMORY Signed-off-by:

The scheduler may raise SQ_WAVE_STATUS.SPI_PRIO via SQ_CMD before context restore has completed. Restoring SPI_PRIO=0 after this point may cause context save to fail as the lower priority wavefronts are not selected for execution among spin-waiting wavefronts. Leave SPI_PRIO at its SPI-initialized or scheduler-raised value. v2: Also fix race with exception handler Signed-off-by:

This is needed to prevent deadlocks when MMU notifiers run in reclaim-FS context and take the DQM lock for userptr evictions. Previously this was done by making all memory allocations under DQM locks GFP_NOIO. This is error prone. Using memalloc_nofs_save/restore will reliably affect all memory allocations anywhere in the kernel while the DQM lock is held. Signed-off-by:

Merge tag 'exynos-drm-next-for-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next Cleanups - Change g2d driver to component based driver . g2d driver was last customed sub driver so this patch series changes it to component based driver, which also makes gem handling to be more simplify. - Cleanup of Exynos DRM suspend/resume . Register exynos drm core suspend/resume functions to prepare/complete callbacks of dev_pm_ops instead of suspend/resume callbacks to ensure exynos_drm_suspend() is called before any suspend callback from the real devices to avoid some issues on boards with complex pipelines. . Also Add pm_runtime_furce_suspend/resume as SYSTEM_SLEEP_PM_OPS to ensure that resources of each devices will be released for the system PM suspend/resume cycle. - Remove local value not used.

cik_pcie_gen3_enable() is only called by cik_common_hw_init(), which is never called in atomic context. cik_pcie_gen3_enable() calls mdelay() to busily wait, which is not necessary. mdelay() can be replaced with msleep(). This is found by a static analysis tool named DCNS written by myself. Signed-off-by:
