https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/7028,
because we won't change working directory to the repo now, instead,
we will use any working directory. If we set working directory to
a path contains repo and the custom --data-dir, the problem in this
issue should be solved.
Howewer, this may be treated as an incompatible change if some code
assume the working directory is always the repo.
Also, there may be another solution that always let --data-dir be the
subdirectory of the repo, but personally I think this may not be what
we actually need.
As this issue mainly influent on Docker and I am not familiar with
.bat files, updating webui.bat is skipped.
webui.sh: source env from repo instead $PWD
This adds the GFX version 9.0.0 in order to use Renoir GPUs with at least 4 GB of VRAM (it's possible to increase the virtual VRAM from the BIOS settings of some vendors). This will only work if the remaining ram is at least 12 GB to avoid the system to become unresponsive on launch.).
This change also changes the GPU check to a case statement to be able to add more GPUs efficiently.
The problem: Some Linux distrubutions, like NixOS, use a
non-standard filesystem. This causes the bash program to not
be at /bin/bash (though /usr/bin/env is always there).
