<id>urn:sha1:425285d39afddaf4a9dab36045b816af0cc3e400</id>
<content type='text'>
Add trace for amdgpu runpm separate funcs usage and this will
help debugging on the case of runpm usage missed to dereference.
In the normal case the runpm usage count referred by one kind
of functionality pairwise and usage should be changed from 1 to 0,
otherwise there will be an issue in the amdgpu runpm usage
dereference.

<content type='text'>
Let amdgpu_vm_handle_moved update all BO VA mappings of BOs reserved by
the caller. This will be useful for handling extra BO VA mappings in
KFD VMs that are managed through the render node API.

v2: rebase against drm_exec changes (Alex)

In amdgpu_dma_buf_move_notify reserve fences for the page table updates
in amdgpu_vm_clear_freed and amdgpu_vm_handle_moved. This fixes a BUG_ON
in dma_resv_add_fence when using SDMA for page table updates.

<title>drm/amdgpu: Add EXT_COHERENT memory allocation flags</title>

<content type='text'>
These flags (for GEM and SVM allocations) allocate
memory that allows for system-scope atomic semantics.

On GFX943 these flags cause caches to be avoided on
non-local memory.

On all other ASICs they are identical in functionality to the
equivalent COHERENT flags.

Corresponding Thunk patch is at

<content type='text'>
Add mem_id_plus1 parameter to amdgpu_gem_object_create and pass it to
amdgpu_bo_create. For dGPU mode allocation, mem_id is used by VRAM
manager to get the memory partition fpfn, lpfn from xcp manager. For APU
native mode allocation, mem_id is used to get NUMA node id from xcp
manager, then pass to TTM as numa pool id to alloc memory from the
specific NUMA node. mem_id -1 means for entire VRAM or any NUMA nodes.

<title>drm/amdgpu: Set MTYPE in PTE based on BO flags</title>
<updated>2022-11-09T22:41:42Z</updated>

<name>Felix Kuehling</name>

<published>2022-08-26T22:22:35Z</published>
<link rel='alternate' type='text/html' href='https://git.shady.money/linux/commit/?id=d1a372af1c3d834c2346b2e822cd6c40abc09866'/>
<id>urn:sha1:d1a372af1c3d834c2346b2e822cd6c40abc09866</id>
<content type='text'>
The same BO may need different MTYPEs and SNOOP flags in PTEs depending
on its current location relative to the mapping GPU. Setting MTYPEs from
clients ahead of time is not practical for coherent memory sharing.
Instead determine the correct MTYPE for the desired coherence model and
current BO location when updating the page tables.

To maintain backwards compatibility with MTYPE-selection in
AMDGPU_VA_OP_MAP, the coherence-model-based MTYPE selection is only
applied if it chooses an MTYPE other than MTYPE_NC (the default).

Add two AMDGPU_GEM_CREATE_... flags to indicate the coherence model. The
default if no flag is specified is non-coherent (i.e. coarse-grained
coherent at dispatch boundaries).

Update amdgpu_amdkfd_gpuvm.c to use this new method to choose the
correct MTYPE depending on the current memory location.

v2:
* check that bo is not NULL (e.g. PRT mappings)
* Fix missing ~ bitmask in gmc_v11_0.c
v3:
* squash in "drm/amdgpu: Inherit coherence flags on dmabuf import"
