2022-04-14drm/amdgpu: Fix one use-after-free of VMxinhui pan
VM might already be freed when amdgpu_vm_tlb_seq_cb() is called. We see the calltrace below.

2022-04-05drm/amdgpu: fix TLB flushing during evictionChristian König
Testing the valid bit is not enough to figure out if we need to invalidate the TLB or not. During eviction it is quite likely that we move a BO from VRAM to GTT and update the page tables immediately to the new GTT address. Rework the whole function to get all the necessary parameters directly as value.

2022-02-23drm/amdgpu: check vm ready by amdgpu_vm->evicting flagQiang Yu
Workstation application ANSA/META v21.1.4 get this error dmesg when running CI test suite provided by ANSA/META: [drm:amdgpu_gem_va_ioctl [amdgpu]] *ERROR* Couldn't update BO_VA (-16) This is caused by: 1. create a 256MB buffer in invisible VRAM 2. CPU map the buffer and access it causes vm_fault and try to move it to visible VRAM 3. force visible VRAM space and traverse all VRAM bos to check if evicting this bo is valuable 4. when checking a VM bo (in invisible VRAM), amdgpu_vm_evictable() will set amdgpu_vm->evicting, but latter due to not in visible VRAM, won't really evict it so not add it to amdgpu_vm->evicted 5. before next CS to clear the amdgpu_vm->evicting, user VM ops ioctl will pass amdgpu_vm_ready() (check amdgpu_vm->evicted) but fail in amdgpu_vm_bo_update_mapping() (check amdgpu_vm->evicting) and get this error log This error won't affect functionality as next CS will finish the waiting VM ops. But we'd better clear the error log by checking the amdgpu_vm->evicting flag in amdgpu_vm_ready() to stop calling amdgpu_vm_bo_update_mapping() later. Another reason is amdgpu_vm->evicted list holds all BOs (both user buffer and page table), but only page table BOs' eviction prevent VM ops. amdgpu_vm->evicting flag is set only for page table BOs, so we should use evicting flag instead of evicted list in amdgpu_vm_ready(). The side effect of this change is: previously blocked VM op (user buffer in "evicted" list but no page table in it) gets done immediately. v2: update commit comments.

Why: Previously hw fence is alloced separately with job. It caused historical lifetime issues and corner cases. The ideal situation is to take fence to manage both job and fence's lifetime, and simplify the design of gpu-scheduler. How: We propose to embed hw_fence into amdgpu_job. 1. We cover the normal job submission by this method. 2. For ib_test, and submit without a parent job keep the legacy way to create a hw fence separately. v2: use AMDGPU_FENCE_FLAG_EMBED_IN_JOB_BIT to show that the fence is embedded in a job. v3: remove redundant variable ring in amdgpu_job v4: add tdr sequence support for this feature.

For GTT allocations with a GART address the res contains the VMID0 addresses and can't be used for VM handling. So ignore the res when the pages array is given or we fill the page tables with nonsense.

2021-06-02drm/ttm: rename bo->mem and make it a pointerChristian König
When we want to decouble resource management from buffer management we need to be able to handle resources separately. Add a resource pointer and rename bo->mem so that all code needs to change to access the pointer instead. No functional change.

2021-06-01drm/amdgpu: Fix a bug on flag table_freedEric Huang
table_freed will be always true when mapping a memory with size bigger than 2MB. The problem is page table's entries are always existed, but existing mapping depends on page talbe's bo, so using a check of page table's bo existed will resolve the issue.
