[Touch-packages] [Bug 1931725] Re: initramfs-tools & kernel: use zstd as the default compression method
** Also affects: linux-oracle (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-oracle (Ubuntu) Status: New => Fix Committed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1931725 Title: initramfs-tools & kernel: use zstd as the default compression method Status in Ubuntu on IBM z Systems: Fix Released Status in initramfs-tools package in Ubuntu: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux-oracle package in Ubuntu: Fix Committed Bug description: Turns out that loading is always the slow part in loading initramfs into memory and decompressing it since decompression is always the final 10-20% or so of the task. It therefore makes sense to use a good compressor that shrinks the initramfs as much as possible with little decompression overhead. Benchmarking zstd vs lz4 shows that while zstd can be ~5x slower in decompression, the image size is much smaller with zstd than lz4, and since ~80-90% of the boot time is loading the image it makes sense to use zstd. Attached is a libreoffice spread sheet showing typical load and decompression times for a fairly standard 3.4 GHZ intel box with data for load times for a 5400 RPM, 7200 RPM and SATA SSD drives. The conclusions from the test results (attached) show: 1. Loading time is always significantly slower than decompression time. 2. ZSTD is 5x slower than LZ4 in decompression speed but produces far better compressed images 3. Given that loading time is the major factor in loading + decompression, ZSTD is best for kernel and initramfs boot timings. (Also refer to https://kernel.ubuntu.com/~cking/boot-speed- eoan-5.3/kernel-compression-method.txt for some raw data on drive load speeds for the same UEFI box I did a couple of years ago). amd64 supports zstd, but s390x does not. Will use this bug to enable zstd support on s390x.

[Touch-packages] [Bug 1877088] Re: [UBUNTU 20.04] installkernel script does not symlink /boot/initrd.img which is required with the default zipl.conf
** Description changed: + [Impact] + + * initrd link is not updated when using installkernel or "make install" + from kernel sources. This leads to boot failure after installing a new + kernel with mentioned methods because the kernel does not match initrd. + + * It's a regression because for Focal it was working before. + + * Issue was reproduced also on Bionic. + + * The proposed fixed by Stefan Bader adds a hook in + /etc/kernel/postinst.d/ so installkernel will relink the initrd. The + kernel DEB packages should not be affected. + + [Test Plan] + When testing development kernels I usually rely on the installkernel script either through the "make install" target of the Kernel source or manually. This used to work great on Ubuntu on Z. On Ubuntu 20.04 (freshly installed up to date) this fails however because /boot/initrd.img is not updated (/boot/vmlinuz is) and thus zipl installs the wrong kernel/initrd combination rendering the system unbootable.
