It does indeed short-circuit on || (If the left side of an || statement is not
0, it doesn't evaluate the right side and returns true). So we can ignore this
patch, since checking for each individual field on the 2nd term is probably
overkill. We were still inv

Good point, as if (1 || 0) should short-circuit at the if (1) part. Thus we
should go down to NOTIFY_DONE if m is NULL. Yazen can confirm here, as he was
the one who with me when we found the original issue. It's possible that one of

Wonder how it goes any further when m is NULL. It should do shortcut
evaluation and return NOTIFY_DONE, right? Or is this for better readability?
Thanks,

Make sure the register offsets used for HDP flush in VF is
initialized early so that it works fine during any early HDP flush
sequence. For that, move the offset initialization to *_remap_hdp.

HDP flush is used early in the init sequence as part of memory controller
block initialization. Hence remapping of HDP registers needed for flush
needs to happen earlier.
This also fixes the AER error reported as Unsupported Request during
driver load.

I think so, we indeed need a new message indicating suspend, e.g. runtime
suspend has completed. I will provide a new patch for this.

Patch 1 adds kfd_lock_pdd_by_id and patch 2 adds kfd_unlock_pdd helpers,
broken out this way to reduce noise in the first patch, which is a bit
tricky because of modifying a lot of error paths. Patch 2 is trivial.
Daniel Phillips (2):
drm/amdgpu: Use kfd_lock_pdd_by_id helper in more places

Convert most of the "mutex_lock; kfd_process_device_data_by_id" occurrences
in kfd_chardev to use the kfd_lock_pdd_by_id. These will now consistently
log debug output if the lookup fails. Sites where kfd_process_device_data_by_id
is used without locking are not converted for now.
