Add buildroot utils/check-package check to the pr-checks.yml workflow.
It checks for common errors/mistakes when creating own buildroot
packages. Also fixed all warnings this utility output for our existing packages.
* Linux: Update kernel 5.10.61 for ODROID-N2 (#1512)
Update the kernel to 5.10.61 for ODROID-N2 and fix the update script
to update kernel for ODROID-N2 next time too.
* Move ODROID kernel patches to non-kernel version specific directory
The minimal memory reserved parameter vm.min_free_kbytes should be
between 1-3% according to RedHat.
However, the kernel by default reserves around 3MB (e.g. only 3285 on a
32-bit Raspberry Pi 4 2GB installation). This seems to be too low for
network intensive applications such as ours: Under memory pressure
"page allocation failure" on various orders have been observed.
Raspberry Pi OS uses a fixed value of 16MB. Follow this setting for now.
Note: We cannot set this globally for Home Assistant: x86-64 machines
can have quite a bit more memory, which also requires increased
min_free_kbytes parameter. ODROID-N2 on the other hand uses transparent
huge pages: If enabled, the kernel requires higher min_free_kbytes
values, and sets those also by default (e.g. on ODROID-N2+ with 4GB
memory its set to 22528 by default).
Don't fail adding reserved memory when a memory region already has been
reserved (e.g. via memreserve). This avoids conflicting no-map setting
and makes sure memory is properly reserved.
* Enable some useful kernel configurations
* Add xe-guest-utilities for better Xen support
Add guest utilities and make sure the Xen guest daemon gets started
when running under Xen virtualization.
Other compression methods remove the original image file at compression.
Add the -m (move) command to zip to do the same when compressing with
zip. This saves some space in the builds image/release directory.
The CRDA (Central Regulatory Domain Agent) utility has been used as a
user space helper to load regulatory information for WiFi drivers.
However, since Linux 4.15 the kernel can load the regulatory information
directly from a signed firmware file "regulatory.db".
The regulatory.db file is provided by the WIRELESS_REGDB package, which
has been already installed since its a dependency of CRDA.
Drop CRDA and select WIRELESS_REGDB package explicitly to make sure the
regulatory.db file is present.
LVM2 is not really required in the embedded use case. Opt out of
installing the standard installation which will install only dmsetup.
This requires a backported fix for the lvm2 package to not install
unnecessary systemd services.
Fixes: #1448
* Add squashfs with LZ4 and LZO compression to Barebox
* Add squashfs with LZO compression to U-Boot
* Use squashfs for Linux kernel partition
Generate a squashfs image with LZO compression for the Linux kernel
partition. Adjust the boot scripts to be file system independent commands
to boot from squashfs.
The patches for ODROID-C2/C4 don't apply to Linux 5.12 used in
ODROID-N2. Move ODROID-C2/C4 patches to kernel version specific
directory so they don't get applied for ODROID-N2.
Use the latest Linux stable release 5.12 for ODROID-N2. This allows to
test if we see the random kernel crashes observed with 5.10 in latest
stable 5.12 as well.
The rauc hook for the spl slotclass writes to the disk directly. Make
sure the changes do not end up in cache in case the device looses power
or is otherwise not properly rebooted.
Also use the same partition label detection we are using in
hassos-expand.
In the past file system extents have been deactivated to get better
performance in U-Boot. However, the performance issue has been addressed
with commit d5aee659f217 ("fs: ext4: cache extent data") in U-Boot. The
performance should be equal to regular files using no extents.
Enabling extents has an advantage however: Files are stored more
efficently, especially relatively large files like a kernel image. The
impact is not all that big (~100KiB), but worthwhile nonetheless.
The Wireless Extension framework is deprecated, but it seems that the
Wireless Extensions proc API is still popular (/proc/net/wireless).
Enable the minimal set of Wireless Extension to get the proc API.
Since we start the HomeAssistant shell directly on tty the service
responsible for starting did not restart the shell on exit. Remove the
RemainAfterExit flag to make sure that the shell restarts on exit.
It seems that the TPU (thermal monitoring) sometimes reports
unreasonable high temperatures, leading the kernel to trigger a thermal
shutdown. Add a patch which filters out such spurious temperature
readings.
* Remove CONFIG_CLOCKSOURCE_EFI configuration
It seems to cause messages like this on some machines:
EFI Event timer too slow freq = 100 Hz
The Barebox efi_defconfig configurationd doesn't enable it either.
Disable it by default as well.
* Enable CONFIG_CMD_ECHO_E to fix menutree
It seems that menutree needs CONFIG_CMD_ECHO_E to properly display the
boot menu.
Also enable other useful commands such as edit or reset.
* Bump Barebox to 2021.05.0
Since the move to 5.10 multiple users experience stability issues
leading to random crashes. All reboots follow a SError Interrupt:
[48112.247242] SError Interrupt on CPU5, code 0xbf000000 -- SError
...
Revert back to Linux 5.9.16 for now.
Using console focused virtualization environments such as virsh having
a serial console is the easiest way to interact with a virtual machine.
It also saves resources since no video memory needs to be allocated.
Enable serial console besides tty1 by default.
Note: The bootloader as well as the kernel shows its boot messages on
all consoles. However, only the last console is mapped to /dev/console,
which systemd is using to show service startup messages. Putting tty1 as
last console makes sure that systemd messages are still shown on the
console screen.
When using quotes currently, they are not passed to HA due to $*. This
doesn't allow to use some commands properly, e.g. snapshot restore with
a passwort with spaces:
```
ha snapshot restore c31f3c93 --password "test test"
...
time="2021-05-26T11:24:19+02:00" level=fatal msg="Error while executing rootCmd: accepts 1 arg(s), received 2"
```
Properly pass all arguments using $@ in quotes.
