I can now test on powermac 7,3 (with an ATI card)
How can I build a deb package of this kernel ? Or is there a package to download somewhere ?
I've tested the 5.5-rc package with the link you gave hereafter. When
you said "working kernel", did you mean it would not crash ? It doesn't
for me. I can boot successfully.
The only weirdness I could notice is that my swap space wasn't mounted.
When I tried to run swapon, I was given the following (roughly
translated from french) :
swapon: /dev/sdb5 : pagesize doesn't fit with space space format
unable to find swap-space signature
So I ran mkswap on the partition, I could then run swapon successfully.
But, when I boot the old kernel ( 5.3), I've got the same error again on
swap and I have to format the swap space to mount it manually.
There's something wrong on swap page size between those two kernels.
I usually cross-compile on x86-64 from upstream sources. On a Debian
Buster with the powerpc tools installed,
it's just:
#####
make ARCH=powerpc CROSS_COMPILE=powerpc64-linux-gnu- oldconfig && nice
-19 make ARCH=powerpc CROSS_COMPILE=powerpc64-linux-gnu- -j56
bindeb-pkg
####
(alter the -j56 for your own build system). For the dependency, as far
as I remember I only needed "gcc-powerpc64-linux-gnu" and
dependencies. My '.config' is Debian's 5.3 plus default values for
changes - with the exception of 4 KiB pages.I should use the same and the same config file also.
I'll try this later. Should I download the 5.5-rc1 kernel source or
something else ?
I've also uploaded the working kernel with 4 KiB pages DEB here:
<http://dl.free.fr/otB1KMEMR>, as it might be easier for a quick test.
Cordially,
Cheers,
Bertrand
