CROS amd64-generic R106 looks not working on intel GPU.

[Ted]

Hi developers.

I am facing a problem, and this is how I approach to the problem.

But I am not sure. 

So I want to ask advise or help to you guys. Thank you in advance.

CROS (amd64-generic R106) UI doesn't work on the intel GPU (but previous R101 UI was working).

So I found a dubious warning message from ui log (plz refer attached log file).

1 libEGL warning: MESA-LOADER: failed to open crocus: /usr/lib64/dri/crocus_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib64/dri, suffix _dri)
  2
  3 2022-09-03T18:41:04.873085Z ERROR chrome[2548:2548]: [gl_display.cc(508)] EGL Driver message (Error) eglInitialize: DRI2: failed to load driver

And there is no crocus_dri.so in R106 /usr/lib64/dri/

only

kms_swrast_dri.so

nouveau_dri.so

nouveau_drv_video.so

r300_dri.so

r600_dri.so

r600_drv_video.so

swrast_dri.so

are exist.

(but there is i965_dri.so in R101)

What kind of source files are changed from R101 to R106?

Do I have to add some VIDEO_CARDS flags in /src/overlays/overlay-amd64-generic/profiles/base/make.defaults?

Or do I have to add some USE flags in media-libs/mesa?

What should I fix?

[Ted]

In order to build the  /usr/lib64/dri/crocus_dri.so , what kind of USE flag or VIDEO_CARDS should I add?

Below is mesa information.
