The default 'max' cpu of qemu-user emulates SVE and pointer
authentication, which aarch64 binaries use and which is expensive to
emulate. Default QEMU_CPU to neoverse-n1 for aarch64 builds and exec,
unless it is already set. neoverse-n1 needs qemu 7.1 or later, the
documentation says how to choose another cpu.
Building an EL10 image with mlnx-ofa_kernel-dkms and doca-ofed-userspace
on an EL10 x86_64 host with qemu 10.2:
DOCA build Total
aarch64, master 3270 s (54.5 min)
aarch64, branch 2399 s (40 min), −27%
x86_64, native 251 s (4 min)
Older qemu-user-static, such as qemu 8.2 of Ubuntu 24.04, emulates
pointer authentication much more slowly, so builds there can get up to
ten times faster.

Versioning and releases
The top-level VERSION file names the release the current branch is working toward. Build scripts
call ./mkversion, which turns it into the version stamped on packages: the tag itself on a release
tag (4.0.1), otherwise a development version (4.0.1~dev5+gdeadbee). Packages sort it before the
release it leads up to. Only setup.py gets the PEP 440 spelling, 4.0.1.dev5+gdeadbee.
mkversion also derives a version from the newest tag reachable from HEAD and uses whichever is
higher, so forgetting to bump VERSION after tagging the current branch cannot walk the version
backwards. Staying ahead of tags on other branches is what VERSION itself is for: patch releases
are tagged on release branches, which master never sees.
Cutting a new series:
- Land the release commit on master and tag
X.Y.0there. - Create branch
X.Yfrom that tag; it inheritsVERSION=X.Y.0. - Only then bump
VERSIONon master. Doing it before step 2 leaves the release branch on the wrong series.
Patch releases land on branch X.Y and are tagged X.Y.Z there; no VERSION edit is needed.
Nightly builds
.github/workflows/nightly.yml builds the rpms (EL9, EL10, SUSE 16) and debs (Ubuntu 24.04, 26.04)
for x86_64 and aarch64 every night that something changed, installs each set on a clean container,
and publishes them as the nightly pre-release. Every bundle there holds all packages for one
target and an INSTALL.txt. Pull requests that touch the packaging run the same build and tests
without publishing. Genesis is not built there yet.
