Thomas, All,
On 2021-06-21 23:01 +0200, Thomas Petazzoni spake thusly:
> The pre-built vexpress kernel used by the testing infrastructure is a
> 4.0.0 kernel, which is getting old to be used with reasonably recent
> toolchains.
>
> This commit updates the pre-built kernels for both the versatile and
> vexpress machines to 5.10.7 (they have already been put online).
This breaks the squashfs tests:
Filesystem uses "lz4" compression. This is not supported
List of all partitions:
1f00 131072 mtdblock0
(driver?)
1f01 32768 mtdblock1
(driver?)
b300 2048 mmcblk0
driver: mmcblk
No filesystem could mount root, tried:
squashfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,0)
And indeed, if we boot this kernel with a gzip-compressed squashfs, ad
we look at the configuration (irrelevant options omitted for brevity):
# zcat /proc/config.gz |grep SQUA
CONFIG_SQUASHFS=y
CONFIG_SQUASHFS_ZLIB=y
# CONFIG_SQUASHFS_LZ4 is not set
CONFIG_SQUASHFS_LZO=y
# CONFIG_SQUASHFS_XZ is not set
Could you rebuild the kernel (but not nice for those like who already
have it cached locally), or build a newer-yet kernel?
Or should we just change our test(s) to use lzo instead of lz4?

Yann E. MORIN.
