Single line function usually doesn't look that useful to me.
Why is that any improvement?

Hi Christian,
My intention is to use a paired generic gmc alloc/free function to proceed PDB bo. Current code is gmc v9 code calls amdgpu_gmc_pdb0_alloc to allocate PDB bo buffer, and release the bo directly in gmc_v9_0_sw_fini. I guess PDB bo is not a gmc v9 specific buffer, so it's better to use a release function from amdgpu_gem.c in fini. This may benefit the case that users do the same in GMC newer IP code.
Regards,
Guchun

Mhm, actually that is indeed purely gmc 9 specific.
This is a workaround for a very specific hardware bug issue which will
hopefully never happen again :)
We just implemented it in the common handler to be able to test it with
gmc 8 before gmc 9 came out of production.
Do we have a generic amdgpu_gmc_sw_finit()? If yes I would put it there
instead, if no we might want to create one.
Regards,
Christian.

Thanks for the info, Christian, and I will abandon this patch. We don’t have a generic amdgpu_gmc_sw_fini.
