d7f1487643 drm/amdgpu: always force full reset for SOC21
There are cases where soft reset seems to succeed, but
does not, so always use mode1/2 for now.

c25d09bcb7 drm/amdgpu: fix deadlock while reading mqd from debugfs
An errant disk backup on my desktop got into debugfs and triggered the
following deadlock scenario in the amdgpu debugfs files. The machine
also hard-resets immediately after those lines are printed (although I
wasn't able to reproduce that part when reading by hand):

amdgpu_debugfs_mqd_read() holds a reservation when it calls
put_user(), which may fault and acquire the mmap_sem. This violates
the established locking order.

Bounce the mqd data through a kernel buffer to get put_user() out of
the illegal section.

eb4f6eca26 drm/amdgpu: Fix truncations in gfx_v11_0_init_microcode()

927a8a800e drm/amdgpu: Fix truncation in gfx_v10_0_init_microcode
The total size of the fw_name buffer is 8 (for "amdgpu/") + 30 (for
ucode_prefix) + 5 (for "_pfp") + 5 (for "_wks") + 5 (for ".bin") = 53
characters.

20fd14460f drm/amdgpu: Fix 'fw_name' buffer size to prevent truncations in amdgpu_mes_init_microcode
The snprintf function is used to write a formatted string into fw_name.
The format of the string is "amdgpu/%s_mes%s.bin", where %s is replaced
by the string in ucode_prefix and the second %s is replaced by either
"_2" or "1" depending on the condition pipe == AMDGPU_MES_SCHED_PIPE.

The length of the string "amdgpu/%s_mes%s.bin" is 16 characters plus the
length of ucode_prefix and the length of the string "_2" or "1". The
size of ucode_prefix is 30, so the maximum length of ucode_prefix is 29
characters (since one character is needed for the null terminator).
Therefore, the maximum possible length of the string written into
fw_name is 16 + 29 + 2 = 47 characters.

The size of fw_name is 40, so if the length of the string written into
fw_name is more than 39 characters (since one character is needed for
the null terminator), it will be truncated by the snprintf function, and
thus warnings will be seen.

By increasing the size of fw_name to 50, we ensure that fw_name is
large enough to hold the maximum possible length of the string, so the
snprintf function will not truncate the output.

Fixes the below with gcc W=1:

b6c4f90b38 drm/amdgpu: sync page table freeing with tlb flush
The idea behind this patch is to delay the freeing of PT entry objects
until the TLB flush is done.

This patch:
- Adds a tlb_flush_waitlist in amdgpu_vm_update_params which will keep the
  objects that need to be freed after tlb_flush.
- Adds PT entries in this list in amdgpu_vm_ptes_update after finding
  the PT entry.
- Changes functionality of amdgpu_vm_pt_free_dfs from (df_search + free)
  to simply freeing of the BOs, also renames it to
  amdgpu_vm_pt_free_list to reflect this same.
- Exports function amdgpu_vm_pt_free_list to be called directly.
- Calls amdgpu_vm_pt_free_list directly from amdgpu_vm_update_range.

V2: rebase
V4: Addressed review comments from Christian
    - add only locked PTEs entries in TLB flush waitlist.
    - do not create a separate function for list flush.
    - do not create a new lock for TLB flush.
    - there is no need to wait on tlb_flush_fence exclusively.

V5: Addressed review comments from Christian
    - change the amdgpu_vm_pt_free_dfs's functionality to simple freeing
      of the objects and rename it.
    - add all the PTE objects in params->tlb_flush_waitlist
    - let amdgpu_vm_pt_free_root handle the freeing of BOs independently
    - call amdgpu_vm_pt_free_list directly

V6: Rebase
V7: Rebase
V8: Added a NULL check to fix this backtrace issue:

d8a3f0a034 drm/amdgpu: implement TLB flush fence
The problem is that when (for example) 4k pages are replaced
with a single 2M page we need to wait for change to be flushed
out by invalidating the TLB before the PT can be freed.

Solve this by moving the TLB flush into a DMA-fence object which
can be used to delay the freeing of the PT BOs until it is signaled.

V2: (Shashank)
    - rebase
    - set dma_fence_error only in case of error
    - add tlb_flush fence only when PT/PD BO is locked (Felix)
    - use vm->pasid when f is NULL (Mukul)

V4: - add a wait for (f->dependency) in tlb_fence_work (Christian)
    - move the misplaced fence_create call to the end (Philip)

V5: - free the f->dependency properly

V6: (Shashank)
    - light code movement, moved all the clean-up in previous patch
    - introduce params.needs_flush and its usage in this patch
    - rebase without TLB HW sequence patch

V7:
   - Keep the vm->last_update_fence and tlb_cb code until
     we can fix the HW sequencing (Christian)
   - Move all the tlb_fence related code in a separate function so that
     its easier to read and review

V9: Addressed review comments from Christian
    - start PT update only when we have callback memory allocated

V10:
    - handle device unlock in OOM case (Christian, Mukul)
    - added Christian's R-B
