runqemu: time the copy to tmpfs

2021-06-06T22:16:50+00:00

Measure and display the time it takes to copy the rootfs to its new location (usually in tmpfs) to try to understand whether it sometimes takes a lot of time on the autobuilders.

Add support for erofs filesystems

2021-05-31T13:31:01+00:00

Since Linux 5.4 a new read-only filesystem is available, erofs. Compared to squashfs it offers much better read performance with and without compression enabled. It suppports two optional compressors, lz4 and lz4hc. >From the mkfs.erofs man page: EROFS is a new enhanced lightweight linux read-only filesystem with modern designs (eg. no buffer head, reduced metadata, inline xattrs/data, etc.) for scenarios which need high-performance read-only requirements, e.g. Android OS for smartphones and LIVECDs. It also provides fixed-sized output compression support, which improves storage density, keeps relatively higher compression ratios, which is more useful to achieve high performance for embedded devices with limited memory since it has unnoticable memory overhead and page cache thrashing. This commit adds support for three new filesystem targets: erofs: erofs without compression erofs-lz4: erofs with lz4 compresssion enabled erofs-lz4hc: erofs with lz4hc compression enabled (From OE-Core rev: 41dead1ff8ccc49e6cd6e6f5d41a59d164693e0d) Signed-off-by: Richard Weinberger Signed-off-by: Richard Purdie

qemu: use 4 cores in qemu guests

2021-05-13T17:09:10+00:00

Each of the cores is mapped to a thread on the host, this should speed up things inside qemu which can take advantage of that. (From OE-Core rev: 56f98d12a79585a4d4c459160f39403e05b620a5) Signed-off-by: Alexander Kanavin Signed-off-by: Richard Purdie

yocto-check-layer: Only note a layer without a conf/layer.conf (versus error)

2021-05-06T15:55:35+00:00

Dynamic layers may have a conf directory, but don't need (or want) a conf/layer.conf This isn't an error, so we can just log it and indicate the layer is being skipped. A full layer without a conf file isn't all that useable, so we aren't letting anything subtle slip through by just logging it.

classes/lib/scripts: Use bb.utils.rename() instead of os.rename()

2021-05-06T10:16:23+00:00

Incremental build in Docker fails with: OSError: [Errno 18] Invalid cross-device link when source and destination are on different overlay filesystems. Rather than adding fallback code to every call site, use a new wrapper in bitbake which detects this case and falls back to shutil.move which is slower but will handtle the overlay docker filesystems correctly.

oe-buildenv-internal: add BitBake's library to PYTHONPATH

2021-05-06T07:41:26+00:00

There are many Python scripts in oe-core that want to use Tinfoil, and right now they have to know where they are to work out where BitBake is likely to be. This is suboptimal as BitBake could be somewhere else, so this approach doesn't scale to other layers at all. Solve this by adding BITBAKEDIR/lib to PYTHONPATH in oe-buildenv-internal, so that Python has BitBake on its search path once the build system is configured.

pybootchart/draw: Avoid divide by zero error

2021-05-02T22:21:42+00:00

When disk stats don't run frequenctly enough, we see divide by zero errors. The code already has a fallback path so ensure we use it for this case too. [YOCTO #14360] (From OE-Core rev: b71d30aef5dc2c360432c0dd4147859dd303ea48) Signed-off-by: Richard Purdie

yocto-check-layer: Avoid bug when iterating and autoadding dependencies

2021-04-24T16:53:05+00:00

If iterating a layer with multiple components and auto-adding dependencies the tests can break since layers are never removed and order isn't guaranteed to account for that. Fix this by resetting the layer list back to the original list each time before auto-adding the dependencies in each case. This fixes scanning of meta-openembedded in particular where the sublayers may not be added in order of minimal dependency.

runqemu: Ensure we cleanup snapshot files after image run

2021-04-22T23:08:38+00:00

We need to cleanup snapshot files if we make a copy of them to ensure the tmpfs doesn't run out of space. There is already NFS code needing this so make it a generic code path. (From OE-Core rev: a3e0eec5a4785a0c4859455eb10b43aa832e606d) Signed-off-by: Richard Purdie
