Vivien,
Thanks for the report! Sorry it took me a while to get back to
you.
As discussed in #guix, an immediate work-around is:
(initrd-modules
;; This cannot be built as a module for linux-libre-lts.
((@ (srfi srfi-1) delete) "simplefb" %base-initrd-modules))
I'm not sure what to do going forward. I see two reasonable
solutions. Perhaps there are more, and I welcome suggestions.
One is to provide a separate %base-initrd-modules-lts list that's
equivalent to the snippet above. It's… not great, but then
linux-libre-lts itself isn't documented and people still seem to
find it. If someone were to document it, they could also add a
note about modules.
A more straightforward route is to simply build in simplefb even
for kernels 5.15 and beyond. Apart from an (unmeasured) size
increase of the base image, the main drawback here is that we lose
our long-standing CONFIG_DRM_SIMPLEDRM=m due to a conflict:
- CONFIG_DRM_GEM_SHMEM_HELPER=y
- CONFIG_DRM_SIMPLEDRM=m
+ # CONFIG_DRM_SIMPLEDRM unset tristate: Simple framebuffer driver
- CONFIG_FB_SIMPLE=m
+ CONFIG_FB_SIMPLE=y tristate: Simple framebuffer support
When preparing <https://issues.guix.gnu.org/51619> I considered
this a regression and hence bad, but maybe nobody cares…?
Kind regards,
T G-R
