Existing QUEUE_TYPE_SDMA means PCIe optimized SDMA queues. Introduce a new QUEUE_TYPE_SDMA_XGMI, which is optimized for non-PCIe transfer such as XGMI. Signed-off-by:

Previous codes assumes there are two sdma engines. This is not true e.g., Raven only has 1 SDMA engine. Fix the issue by using sdma engine number info in device_info. Signed-off-by:

MEC FW for some new asic requires all SDMA MQDs to be in a continuous trunk of memory right after HIQ MQD. Add a field in device queue manager to hold the HIQ/SDMA MQD memory object and allocate MQD trunk on device queue manager initialization. Signed-off-by:

Previously mqd managers was initialized on demand. As there are only a few type of mqd managers, the on demand initialization doesn't save too much memory. Initialize them on device queue initialization instead and delete the get_mqd_manager interface. This makes codes more organized for future changes. Signed-off-by:

Global function mqd_manager_init just calls asic-specific functions and it is not necessary. Delete it and introduce a mqd_manager_init interface in dqm for asic-specific mqd manager init. Call mqd_manager_init interface directly to initialize mqd manager Signed-off-by:

If using old kernel config file, CONFIG_ZONE_DEVICE is not selected, so CONFIG_HMM and CONFIG_HMM_MIRROR is not enabled, the current driver error message "Failed to register MMU notifier" is not clear. Inform user with more descriptive message on how to fix the missing kernel config option. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109808Signed-off-by:

userptr may cross two VMAs if the forked child process (not call exec after fork) malloc buffer, then free it, and then malloc larger size buf, kerenl will create new VMA adjacent to old VMA which was cloned from parent process, some pages of userptr are in the first VMA, the rest pages are in the second VMA. HMM expects range only have one VMA, loop over all VMAs in the address range, create multiple ranges to handle this case. See is_mergeable_anon_vma in mm/mmap.c for details. Signed-off-by:

Userptr restore may have concurrent userptr invalidation after hmm_vma_fault adds the range to the hmm->ranges list, needs call hmm_vma_range_done to remove the range from hmm->ranges list first, then reschedule the restore worker. Otherwise hmm_vma_fault will add same range to the list, this will cause loop in the list because range->next point to range itself. Add function untrack_invalid_user_pages to reduce code duplication. Signed-off-by:

Only select HMM_MIRROR will get kernel config dependency warnings if CONFIG_HMM is missing in the config. Add depends on HMM will solve the issue. Add conditional compilation to fix compilation errors if HMM_MIRROR is not enabled as HMM config is not enabled. Remove unused function amdgpu_ttm_tt_mark_user_pages. Signed-off-by:

Philip Yang authored
Use HMM helper function hmm_vma_fault() to get physical pages backing userptr and start CPU page table update track of those pages. Then use hmm_vma_range_done() to check if those pages are updated before amdgpu_cs_submit for gfx or before user queues are resumed for kfd. If userptr pages are updated, for gfx, amdgpu_cs_ioctl will restart from scratch, for kfd, restore worker is rescheduled to retry. HMM simplify the CPU page table concurrent update check, so remove guptasklock, mmu_invalidations, last_set_pages fields from amdgpu_ttm_tt struct. HMM does not pin the page (increase page ref count), so remove related operations like release_pages(), put_page(), mark_page_dirty(). Signed-off-by:

There is circular lock between gfx and kfd path with HMM change: lock(dqm) -> bo::reserve -> amdgpu_mn_lock To avoid this, move init/unint_mqd() out of lock(dqm), to remove nested locking between mmap_sem and bo::reserve. The locking order is: bo::reserve -> amdgpu_mn_lock(p->mn) Signed-off-by:

There is a bug found in vml2 xgmi logic: mtype is always sent as NC on the VMC to TC interface for a page walk, regardless of whether the request is being sent to local or remote GPU. NC means non-coherent and will cause the VMC return data to be cached in the TCC (versus UC – uncached will not cache the data). Since the page table updates are being done by SDMA/HDP, then TCC will never be updated and the GC VML2 will continue to hit on the TCC and never get the updated page tables and result in a fault. Heave weigh tlb invalidation does a WB/INVAL of the L1/L2 GL data caches so TCC will not be hit on next request Signed-off-by:

If instruction fetch fails the wave cannot be halted and returned to the shader without raising MEM_VIOL again. Currently the wave is terminated if this occurs, but this loses information about the cause of the fault. The debugger would prefer the faulting wave state to be context-saved. Poll inside the trap handler until TRAPSTS.SAVECTX indicates context save is ready. Exit the poll loop and complete the remainder of the exception handler, then return to the shader. The next instruction fetch will be from the trap handler and not the faulting PC. Context save will then deschedule the wave and save its state. Signed-off-by:

When MEM_VIOL is asserted the context save handler rewinds the program counter. This is incorrect for any source of the exception. MEM_VIOL may be raised in normal operation by out-of-bounds access to LDS or GDS and does not require special handling. Remove PC adjustment when MEM_VIOL has been raised. Signed-off-by:
