Testing Debian kernels on kernelci?

Testing Debian kernels on kernelci?

[Steve McIntyre]

[ CC: to Ben, the debian kernel team lead ]

Hi folks,

In Debian we've just been bitten by quite a nasty kernel bug in our
latest stable release [1], and this has clearly managed to make it
into a release due to a insufficient testing of our kernels on all our
platforms. Most people only have x86 hardware, and doing full
regression testing across multiple Arm, MIPS, etc. platforms is beyond
our capabilities. You know, the usual situation... :-)

Due to my position in the LAVA team in Linaro, I know quite a bit
about kernelci and I'm wondering if it would be possible to get some
of our Debian kernel branches added to the list for at least some
automated boot testing. This would be major help for us.

The last time I looked, KernelCI assumed all essential drivers would be
built in and only supported use of a pre-built initramfs (if any).

Debian kernel packages are modularised almost as far as possible, so
for each kernel build the initramfs will also need to be rebuilt to
include the new kernel modules.

That's not true any more, it will inject all the modules that get built
into the initramfs.  However the distro config is going to get ignored
anyway unless it appears in arch/${ARCH}/configs since the configurations
are pulled from the kernel source.
