Changes in this release ==================
# Device-types
## New device-types
New supported devices: * acer-cb317-1h-c3z6-dedede * dell-latitude-5400-4305U-sarien (split from dell-latitude-5400-sarien) * fsl-ls1046a-frwy * fsl-ls2088a-rdb * fsl-lx2162a-qds * hp-x360-12b-ca0500na-n4000-octopus * lenovo-TPad-C13-Yoga-zork * rk3399-rock-pi-4b * seco-b68 *
## fsl-l*-rdb
Allow to boot from an alternate bank. In order to use this feature, set `uboot_altbank` to `True` in the job context:
```yaml context: uboot_altbank: true ```
Admins should set `uboot_altbank_cmd` in the device-type template.
# lava-dispatcher-host
Add support for docker device sharing under cgroups v2.
Under cgroups v2, device access control is done with BPF programs only. When docker creates a container, it already attaches a BPF program to that container cgroup. lava-dispather-host replaces that BPF program with one of its own, that allows the regular list of devices containers can usually access (`/dev/null`, `/dev/zero`, ...), plus all the devices shared with the container. Subsequent device sharing with the same container overrides that BPF program with a new one
# Scheduler
## Balance job scheduling between submitters
This patch is intended to prevent submitter starvation when jobs have the same priority and single submitter sends a large batch of jobs.
It is implemented by determining a number of already running jobs for each submitter and using it to annotate the jobs submitted to the queue. This allows reordering the job queue for picking a job from the submitter that could potentially be starving for an available device. To ensure fairness in edge cases (equal number of running jobs, single device of given device type) jobs sharing the same set of attributes are randomised.
## Active workers
Only schedule jobs on active workers. When a worker is in maintenance, no jobs will be scheduled on the attached devices.
# kexec
Add an option to download the artifacts from deployment action. The job would look like:
```yaml - deploy: to: download images: kernel: url: https://example.com/Image.bin initrd: url: https://example.com/rootfs.cpio.gz compression: gz - boot: method: minimal auto_login: [...] prompts: - "root@localhost:~# " - boot: method: kexec deploy: true kernel: /boot/Image.bin initrd: /boot/rootfs.cpio.gz command: /usr/sbin/kexec [...] ```
# Overlay
Add support for tar filesystem. This allow to add overlays to nfsrootfs for the boards that use NFS.
