[gentoo-dev] [PATCH v7 0/2] rocm.eclass: new eclass

[Yiyang Wu]

Comparing to v6, rocn.eclass refactorized a lot in v7, thanks to
Michał's critical comments on
https://github.com/gentoo/gentoo/pull/26784.

Now the eclass code base is much cleaner, mostly because specific codes
in phase functions are removed.

Changelog against v6:

1. Remove phase functions rocm_src_configure and rocm_src_test. The code
duplication among ROCm ebuilds are not so large that a common phase
function is necessary. Writing a all-in-one phase function would cause
the eclass hard to maintain.

2. check_rw_permission -> check_amdgpu. Limit the function to check
amdgpu device, and move `addwrite /dev/kfd` from rocm_src_test into it.
So ebuilds can simply call check_amdgpu in src_test and do the reset of
testing.

3. Standardize and simplify codes including bash array handling.

4. ROCM_VERSION is required for all packages, not assumed to be ${PV}.

5. Reshaped the examples according to the changes.

6. Update reference of AMDGPU device map, pointing to codes in an
official repo rather than a summarize hosted on a third-party web page.

I would also like to ask a question. In check_amdgpu, if GPU access
denied, the eclass suggest the user to check whether the portage user is
in render group or not. I would like to print the username, so I tried
use ${USER} but it is not set during src_test.  Previously, I used
${PORTAGE_USERNAME} but its a potage internal variable. Is there an
approach to print the portage username? Would $(whoami) suitable for
this job?
