This patchset was inspired and made on top of the below series:
https://lore.kernel.org/amd-gfx/20250319162225.3775315-1-alexander.deuc...@amd.com/
In the above series, there is a bug fix in many functions named
gfx_vX_0_get_csb_buffer (where X ranges from 6 to 11). After closely
looking at those functions, it became clear that most of the code could
be shared from gfx6 to gfx11. Aside from the code duplication removal,
this also improves maintainability since a bug fix in a shared function
can be propagated to all ASICs.
The first patch of this series created one dedicated file for
encapsulating common GC registers (gc_common_offset.h); this series only
adds registers associated with the CSB. In the future, this file can
keep growing as we identify common registers to be shared in the
gc_common_offset.h.
The second patch introduces the generic gfx_get_csb_buffer function,
which has the same implementation found in gfx_v10_0_get_csb_buffer and
gfx_v11_0_get_csb_buffer (these two functions have the same code). After
that, every patch is dedicated to absorbing one of the csb_buffer
functions from gfx from 9 to 6; notice that some adaptations were
required.
Thanks
