[Message part 4 (text/plain, inline)]

The linux-libre 6.7.x package contains ... as far as I can tell, no
supported arm64/aarch64 platforms! This is a pretty significant
regression from the linux-libre 6.6.x packaging!

This appears to have been introduced in
95a3aaf7ad37bb0717f2c9e3faf6f636b586d133

Unfortunately it is all too easy to drop features with non-x86
platforms... especially if you run make *config from an x86 machine.

For example:

diff -u /gnu/store/dnism9x21x0x15k91ngis54w6pcf7gmi-linux-libre-6.6.12/.config /gnu/store/a6xc9aad9kv8xpy7i94ga74h6hs7gdvk-linux-libre-6.7.3/.config | grep -A20 '# Platform selection'
 # Platform selection
 #
 # CONFIG_ARCH_ACTIONS is not set
-CONFIG_ARCH_SUNXI=y
+# CONFIG_ARCH_SUNXI is not set
 # CONFIG_ARCH_ALPINE is not set
-CONFIG_ARCH_APPLE=y
-CONFIG_ARCH_BCM=y
-CONFIG_ARCH_BCM2835=y
-# CONFIG_ARCH_BCM_IPROC is not set
-CONFIG_ARCH_BCMBCA=y
-# CONFIG_ARCH_BRCMSTB is not set
+# CONFIG_ARCH_APPLE is not set
+# CONFIG_ARCH_BCM is not set
 # CONFIG_ARCH_BERLIN is not set
-CONFIG_ARCH_BITMAIN=y
+# CONFIG_ARCH_BITMAIN is not set
 # CONFIG_ARCH_EXYNOS is not set
 # CONFIG_ARCH_SPARX5 is not set
 # CONFIG_ARCH_K3 is not set
 # CONFIG_ARCH_LG1K is not set

There are basically no CONFIG_ARCH platforms enabled!

I am not sure that all the previous platforms were intentionally added,
but at the very least SUNXI, ROCKCHIP, BCM2835 and probably quite a few
others should be added back. I am currently running Guix System in a
virtualized environment, but in the past I've run it on a sunxi systems
such as pinebook and pine64+... and rockchip systems such as
pinebook-pro, rock64-rk3328 and rockpro64-rk3399.

This also makes me wonder what other more subtle features got dropped
along the way, as well as platform support for other architectures... :/

I don't have the time at the moment to come up with a patch, but 6.7.x
should probably not become the default linux-libre until this is
at least partly fixed...


live well,
