5a104cb97c drm/amdkfd: Improve amdgpu_vm_handle_moved
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)

142262a1c0 drm/amdgpu: Add EXT_COHERENT support for APU and NUMA systems
On gfx943 APU, EXT_COHERENT should give MTYPE_CC for local and
MTYPE_UC for nonlocal memory.

On NUMA systems, local memory gets the local mtype, set by an
override callback. If EXT_COHERENT is set, memory will be set as
MTYPE_UC by default, with local memory MTYPE_CC.

Add an option in the override function for this case, and
add a check to ensure it is not used on UNCACHED memory.

V2: Combined APU and NUMA code into one patch
V3: Fixed a potential nullptr in amdgpu_vm_bo_update

7d3f1d76f3 drm/amdgpu: refine fault cache updates
Don't update the fault cache if status is 0.  In the multiple

5003ca63bc drm/amdgpu: fix slab-out-of-bounds issue in amdgpu_vm_pt_create
Recent code set xcp_id stored from file private data when opening
device to amdgpu bo for accounting memory usage etc, but not all
VMs are attached to this fpriv structure like the vm cases in
amdgpu_mes_self_test, otherwise, KASAN will complain below out
of bound access. And more importantly, VM code should not touch
fpriv structure, so drop fpriv code handling from amdgpu_vm_pt.

ea2c3c0855 drm/amdgpu: fix clearing mappings for BOs that are always valid in VM
Per VM BOs must be marked as moved or otherwise their ranges are not
updated on use which might be necessary when the replace operation
splits mappings.

This fixes random GPU hangs when replacing sparse mappings from the
userspace, while OP_MAP/OP_UNMAP works fine because always valid BOs
are correctly handled there.

Should the VRAM be lost or the page tables need re-creation the token will

This patch updates the PTE flags when translate further (TF) is
enabled:
- With translate_further enabled, invalid PTEs can be 0. Reading
  consecutive invalid PTEs as 0 is considered a fault. To prevent
  this, ensure invalid PTEs have at least 1 bit set.
- The current invalid PTE flags settings to translate a retry fault
  into a no-retry fault, doesn't work with TF enabled. As a result,
  update invalid PTE flags settings which works for both TF enabled
  and disabled case.

4bdb9d6501 drm/amdkfd: simplify vm_validate_pt_pd_bos
We don't need to validate and map root PD specially here,
it would be validated and mapped by amdgpu_vm_validate_pt_bos
if it is evicted.

The special case is when turning a GFX VM to a compute VM,
if vm_update_mode changed, we should make sure root PD gets
mapped. So just map root PD after updating vm->update_funcs
in amdgpu_vm_make_compute whether the vm_update_mode changed
or not.

v3:
 - Add some comments suggested by Christian.

v2:
 - Don't rename vm_validate_pt_pd_bos and make it public.
