commit: https://git.buildroot.net/buildroot/commit/?id=e7f0408f496fbbfac8663c76d308b9f691e19e4a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Commit 3cf2782906d5 (support/testing/infra/emulator.py: update pre-built
kernels) bumped the default kernels used by the testing infra.
However, the newer armv7 kernel (at least) no longer has support for
lz4-compressed squashfs filesystems.
This breaks the squashfs test:
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)
Updating the kernel again is a little bit cumbersome, while fixing the
actual test is relatively trivial, so this is what we do: we switch
over to lzo, which is supported by the new kernel:
# 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
While at it, also drop the superfluous line disabling gzip compression:
it is part of a choice, so enabling one (lzo here) forcibly disables the
others (of which gzip).
