Regressions :-(
Tests which did not succeed and are blocking,
including tests which could not be run:

Tests which did not succeed, but are not blocking:

libxc: add LZ4 decompression support
Since there's no shared or static library to link against, this simply
re-uses the hypervisor side code. However, I only audited the code
added here for possible security issues, not the referenced code in
the hypervisor tree.

xen: add LZ4 decompression support
Add support for LZ4 decompression in Xen. LZ4 Decompression APIs for
Xen are based on LZ4 implementation by Yann Collet.
Benchmark Results(PATCH v3)
Compiler: Linaro ARM gcc 4.6.2
1. ARMv7, 1.5GHz based board
Kernel: linux 3.4
Uncompressed Kernel Size: 14MB
Compressed Size Decompression Speed
LZO 6.7MB 20.1MB/s, 25.2MB/s(UA)
LZ4 7.3MB 29.1MB/s, 45.6MB/s(UA)
2. ARMv7, 1.7GHz based board
Kernel: linux 3.7
Uncompressed Kernel Size: 14MB
Compressed Size Decompression Speed
LZO 6.0MB 34.1MB/s, 52.2MB/s(UA)
LZ4 6.5MB 86.7MB/s
- UA: Unaligned memory Access support
- Latest patch set for LZO applied
This patch set is for adding support for LZ4-compressed Kernel. LZ4 is a
very fast lossless compression algorithm and it also features an extremely
fast decoder [1].
But we have five of decompressors already and one question which does
arise, however, is that of where do we stop adding new ones? This issue
had been discussed and came to the conclusion [2].
Russell King said that we should have:
- one decompressor which is the fastest
- one decompressor for the highest compression ratio
- one popular decompressor (eg conventional gzip)
If we have a replacement one for one of these, then it should do exactly
that: replace it.
The benchmark shows that an 8% increase in image size vs a 66% increase
in decompression speed compared to LZO(which has been known as the
fastest decompressor in the Kernel). Therefore the "fast but may not be
small" compression title has clearly been taken by LZ4 [3].

So it seems that u-boot only supports taking the prefix from the
filename when fetching the pxelinux.cfg file and not when fetching any
files referenced from that config.
I've added a symlink /tftpboot/osstest -> pxe/osstest. Bit of a skanky
hack, hopefully we can get u-boot fixed at some point.
Ian.

Yes, that's a bit ugly.
u-boot can probably never be fixed because doing so might break
existing setups.
Perhaps osstest should have an option to bodge this by prepending the
prefix to all the other filenames.

We've got a beta release of the firmware, so it might be fixable.

That could work. Lets see what the vendor says about the PXE thing...
