trailblazer is a bleeding edge, unstable target for EFI capable ARM64
devices. It runs linux-next and should otherwise be adjusted to support
as many devices as possible.
The goal of trailblazer is to motivate more upstream kernel development by
providing a tighter feedback loop (patches land in -next weeks before they
make it into mainline or stable), as well as encouraging more generic
solutions to the device specific hacks we have in userspace.
On supported devices, trailblazer should reflect the current state of
upstream. It allows users to easily appreciate what feature are
unavailable, and more importantly appreciate when a new feature does get
added upstream.
Due to the instability of linux-next, the plan is to have BPO build
trailblazer images nightly, so if next breaks then the images should
only be broken for a day.

Introduce a linux-next kernel with postmarketOS configs and some
additional device specific configs enabled.
This kernel package will be updated daily to the latest -next tag.

pma!5000 added a new implicit dependency on libinput, because it
specified libinput files in the initramfs file hook. mkinitfs considers
it fatal if it cannot find files listed in a file hook.
Later this could be 'optimized' by adding a -libinput subpkg and an
`install_if=libinput-libs` to add this file hook so it's not installed
everywhere... but the size increase isn't too much for UIs.. someone can
do this later.
> libinput-libs-1.26.0-r0 installed size:
> 476 KiB
This fixes a missing dependency problem where a UI (e.g. "none") doesn't
normally depend on libinput, and mkinitfs would fail because these files
were missing.
mdev is slow and missing features, it also requires that we load all the
modules that we include at once making the boot process slower.
udev is required for unl0kr (and buffyboard), it can also load modules
on demand (and asynchronously). Making the boot process considerably
faster on devices, especially for generic images where we have lots of
drivers for different display panels in the initramfs.
Additionally, import full fat modprobe from the kmod package, this is
required to support compressed modules.
This brings us more in line with other distros and generally improves
compatibility.
If devices use broken kernel modules which don't correctly define
modalias', these drivers may not be loaded by udev. This should be fixed
by defining the missing modalias statements in the driver.
This also runs udev earlier in the init, so that display drivers are
loaded before the splash in case they are needed.

This incorprates the debug-shell functionality directly into the
initramfs, so it's no longer necessary to build and boot a custom
initramfs in order to debug your device.
Additionally, the behaviour of the debug-shell is entirely reworked, It
now creates an ACM serial gadget which can be accessed via any normal
terminal emulator (picocom, minicom, etc; or PuTTY on windows). Rather
than just invoking sh, the debug-shell now creates a respawning getty on
both the new virtual console and the active console (this will either be
the UART console or tty0/1).
It is necessary to spawn these shells via getty since the logging rework
means we can no longer assume that stdin/out/err reference a TTY.
In addition to the above, it is now possible to trigger a log dump by
holding volume up during boot. This can be useful for helping users
debug their devices if the issue doesn't result in a failure that can be
detected in the initramfs.
With these changes, the console-shell and debug-shell hook packages are
reduced to only adding the additional tools/features. console-shell is
still required for fbkeyboard, and debug-shell for the setup_usb_storage
tool.

adjust the check in run_hooks to ensure the directory both exists and

This step is the most likely to go wrong or have issues, and it has side
effects which can make it difficult to run multiple times on one boot.
Move it to after hooks so that e.g. when dropping to a debug shell, we
land before the first call.
This also makes booting to hooks a faster in many cases.

Rework logging to always log the initramfs output to the kernel
ringbuffer and deprecate PMOS_NO_OUTPUT_REDIRECT in favour of following
the kernel loglevel.
I know it seems silly to use syslogd for this, but it's necessary to
buffer writes to /dev/kmsg per-line if we want to correctly set the log
level, and "tee" does not do this (it will write multiple lines at once,
resulting in "<14>" prints in the ringbuffer). The main advantage to
this is that we won't have kernel logs cut in half by initramfs logs
anymore, everything will be nicely line buffered!
The previous logging solution of multiple "tail" commands would actually
fail to log up to the last few lines before a crash due to how tail
works (it polls the file and buffers lines).
I attempted something like this before, but I stopped after running into
ratelimiting issues. These are now resolved by configuring the
printk_devkmsg sysctl.
Dropping PMOS_NO_OUTPUT_REDIRECT:
The general motivations behind PMOS_NO_OUTPUT_REDIRECT was to avoid
cluttering up the console with initramfs logs when they aren't wanted;
this is now handled instead by the kernels logging facility. We log to
the ringbuffer at LOGLEVEL_INFO, so if "quiet" is specified on the
cmdline (or the loglevel is otherwise set above info) then initramfs
logs will also not be shown.

We plan to make a lot of changes to the initramfs which will require
incresaing the size. There are some devices that have literally no free
space for this, so make a -minimal initramfs fork that can continue to
support those while we update the regular initramfs.

PineTab 2 is a successor to the original PineTab from PINE64 released
in mid-2023.
The tablet came with DanctNIX's fork of Arch Linux ARM, comes with
K Desktop Environment as the UI and available with 64GB eMMC/4GB RAM
or 128GB eMMC/8GB RAM.
Changelog since 6.7:
General:
* Adreno 5xx preemtion is now disabled due to hangs it causes.
This makes GPU a lot more cooperative on these platforms.
* Fixed absence of zap-shader region which caused devices with
GPU enabled to freeze the whole system.
* Fixed ath10k Wi-Fi not connecting to 5Ghz networks.
* Incorporated in-kernel pd-mapper patchset, therefore userspace
pd-mapper daemon is not required.
* Kernel cmdline from bootloader is no longer ignored completely,
in other words, not hardcoded. You can now modify cmdline in
deviceinfo file and changes in that file will not be ignored.
Devices:
* Xiaomi Redmi Note 7 (lavender):
* split device trees into 2 variants by panel type (Tianma & BOE)
* GPU + panel support for 2 variants
* Vibrator support
* Connectivity: modem, Wi-Fi and bluetooth support.
* Other/all devices:
* update device trees according to upstream USB stack changes
(related to USB 3 phy support)

(1) the deviceprofile differs from upstream 1.16.3 in the following respects:
(a) -export SXMO_NO_KEYBOARD=1 - allow use of the virtual keyboard
(b) +export SXMO_DMENU_LANDSCAPE_LINES="10"
+export SXMO_DMENU_PORTRAIT_LINES="6" - these two adjust the size of the
displayed dmenu menu.
* NB: All foregoing changes are already merged in sxmo-utils master.
(c) +export SXMO_TOUCHSCREEN_ID="TSC2005 touchscreen" - allows sxmo to
reliably toggle touch screen's enabled status
* The foregoing change is awaiting acceptance by upstream.
(2) The start hook differs from upstream 1.16.3 by the removal of the line that
starts conky. That program pegs N900 CPU usage at 100% all the time. This
change is not upstreamable, at least not for the time being
