2021-05-20btrfs: zoned: fix parallel compressed writesJohannes Thumshirn1-4/+38
When multiple processes write data to the same block group on a compressed zoned filesystem, the underlying device could report I/O errors and data corruption is possible. This happens because on a zoned file system, compressed data writes where sent to the device via a REQ_OP_WRITE instead of a REQ_OP_ZONE_APPEND operation. But with REQ_OP_WRITE and parallel submission it cannot be guaranteed that the data is always submitted aligned to the underlying zone's write pointer. The change to using REQ_OP_ZONE_APPEND instead of REQ_OP_WRITE on a zoned filesystem is non intrusive on a regular file system or when submitting to a conventional zone on a zoned filesystem, as it is guarded by btrfs_use_zone_append.

2021-05-20btrfs: zoned: pass start block to btrfs_use_zone_appendJohannes Thumshirn4-7/+6
btrfs_use_zone_append only needs the passed in extent_map's block_start member, so there's no need to pass in the full extent map. This also enables the use of btrfs_use_zone_append in places where we only have a start byte but no extent_map.

2021-05-20drm/bridge: anx7625: Synchronously run runtime suspend.Pi-Hsun Shih1-2/+2
Originally when using pm_runtime_put, there's a chance that the runtime suspend hook will be run after the following anx7625_bridge_mode_set call, resulting in the display_timing_valid field to be cleared, and the following power on fail. Change all pm_runtime_put to pm_runtime_put_sync, so all power off operations are guaranteed to be done after the call returns.

2021-05-20powerpc: Fix early setup to make early_ioremap() workAlexey Kardashevskiy1-2/+2
The immediate problem is that after commit 0bd3f9e953bd ("powerpc/legacy_serial: Use early_ioremap()") the kernel silently reboots on some systems. The reason is that early_ioremap() returns broken addresses as it uses slot_virt[] array which initialized with offsets from FIXADDR_TOP == IOREMAP_END+FIXADDR_SIZE == KERN_IO_END - FIXADDR_SIZ + FIXADDR_SIZE == __kernel_io_end which is 0 when early_ioremap_setup() is called. __kernel_io_end is initialized little bit later in early_init_mmu(). This fixes the initialization by swapping early_ioremap_setup() and early_init_mmu().

2021-05-19drm/amdgpu: DMA map/unmap when updating GPU mappingsFelix Kuehling1-27/+29
DMA map kfd_mem_attachments in update_gpuvm_pte. This function is called with the BO and page tables reserved, so we can safely update the DMA mapping. DMA unmap when a BO is unmapped from a GPU and before updating mappings in restore workers.

2021-05-19drm/amdgpu: Add multi-GPU DMA mapping helpersFelix Kuehling2-9/+148
Add BO-type specific helpers functions to DMA-map and unmap kfd_mem_attachments. Implement this functionality for userptrs by creating one SG BO per GPU and filling it with a DMA mapping of the pages from the original mem->bo.

2021-05-19drm/amdgpu: Simplify AQL queue mappingFelix Kuehling1-55/+48
Do AQL queue double-mapping with a single attach call. That will make it easier to create per-GPU BOs later, to be shared between the two BO VA mappings on the same GPU. Freeing the attachments is not necessary if map_to_gpu fails. These will be cleaned up when the kdg_mem object is destroyed in amdgpu_amdkfd_gpuvm_free_memory_of_gpu.

2021-05-19drm/amdgpu: Keep a bo-reference per-attachmentFelix Kuehling1-5/+17
For now they all reference the same BO. For correct DMA mappings they will refer to different BOs per-GPU. Signed-off-by: Felix Kuehling <[email protected]> Acked-by: Oak Zeng <[email protected]> Acked-by: Ramesh Errabolu <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2021-05-19drm/amdgpu: Rename kfd_bo_va_list to kfd_mem_attachmentFelix Kuehling2-113/+104
This name is more fitting, especially for the changes coming next to support multi-GPU systems with proper DMA mappings. Cleaned up the code and renamed some related functions and variables to improve readability.
