[gentoo-soc] Week 11 Report for Refining ROCm Packages in Gentoo

[wuyy]

Hello all,

My progress this week is mainly writing wiki and refining rocm.eclass.

Although the current eclass can work with my new ebuilds [1],  Michał
Górny has pointed out various flaws on the Github PR [2]. He also
pointed out the necessity about rocm.eclass, because  it seems like a
combination of two eclasses. In my opinion, rocm.eclass has its value,
mainly for handling USE_EXPANDS and common phase functions. The ugly
part is mainly in rocm_src_test: due to the inconsistency of test
methods of packages in [3], I have to detect which method is using and
do it accordingly. So my plan is to split the one-size-fits-all
rocm_src_test into two functions, corresponding to two scenarios (cmake
test or standalone binary), and let each ebuild decide which to use.
This can avoid detailed detection code that make rocm_src_test bloated.

Wiki writing: I think the main part of ROCm wiki[1] and HIP[2] is nearly
finished. But due to the delay of rocm.eclass, the related information
is not appended (ROCm#Developing guide). There is also a section a
reserved: ROCm#Installation guide. I have little clue on how to write
this part, because ROCm is a wide collection of packages. Maybe a meta
package (there are users working on this) would be helpful.

To be honest I'm a bit anxious, because there is only one week left, but
there are still a lot to be determined and tested on rocm.eclass along
with the sci-libs/roc* ebuilds. I hope I can resolve these core issues
in the last week.
