Replace "args.arch_native" with the direct function call in order to
avoid passing "args" to all functions. This is a step to get rid of this
args-passed-to-all-functions pattern in pmbootstrap.
Add initial support for the on-device installer in pmbootstrap. Let
pmbootstrap create a regular split image, then prepare a new installer
rootfs and copy the previously generated rootfs image into the installer
rootfs. Put the installer rootfs into a new image, with reserved space.
There is more to do from here, such as disabling the generation of the
user account when using --ondev. But this requires support in
postmarketos-ondev first, so let's build that iteratively.

When using pmbootstrap, you usually select the device you want to work
on using 'pmbootstrap init', generate the rootfs and can then run more
commands in the context of the device.
The same needs to be done before using QEMU (to generate the rootfs).
But for some reason 'pmbootstrap qemu' requires setting the --arch
parameter when running QEMU for a foreign architecture, even when the
device is still selected in pmbootstrap.
Even more confusing is that setting "--arch arm" always selects
device-qemu-vexpress, but this is not immediately clear from the name.
Let's make this a lot more intuitive by making sure there is a QEMU
device selected when running 'pmbootstrap qemu'. We can then use the
device information to infer the architecture automatically.
mesa-dri-swrast and mesa-dri-virtio are both provided by mesa-dri-gallium
now, so this option does not have much use anymore. With both selections,
exactly the same packages are installed.
While at it, also remove unnecessary "#!/usr/bin/env python3" in files
that only get imported, and adjust other empty/comment lines in the
beginnings of the files for consistency.
This makes files easier to read, and makes the pmbootstrap codebase more
consistent with the build.postmarketos.org codebase.
The important part about this patch is the change for armhf, which
adjusts the hostspec to the one used by Alpine.
Fixes a part of postmarketOS/pmaports#363
Overview:
In order to execute foreign arch binaries on the host system, we are
using the Linux kernel's binfmt_misc feature in combination with
static builds of QEMU. Before this patch, the statically compiled
QEMU binaries were taken from Debian (mostly because I did not realize
that Alpine ships them as well). Now we can use the ones from the aport.
Benefits:
This allows us to easily update and patch the QEMU executables, we
don't need to be in sync with Debian's versions anymore.
Alpine's package is more modular, so we can save some download,
install, zap time, as well as disk space: setting up an armhf chroot
with pmbootstrap took ~102 MB before, now it's ~18 MB.
Detailed changes:
* Remove `cross/qemu-user-static-repack` aport
* Add `data/qemu-user-binfmt.txt` with the binfmt_misc flags for ELF
binaries of various arches (extracted from Debian's packaging)
* When parsing that file, don't write verbose messages to
`pmbootstrap log` anymore, only to the verbose log (can be enabled
with `pmbootstrap -v`)
* Rename `pmb.parse.arch.alpine_to_debian()` to ...`alpine_to_qemu()`
* Rename `arch_debian` to `arch_qemu`
This PR makes the workflow faster and pmbootstrap will
produce less traffic. Details:
* Check if it's possible to create and read from a device
node directly when initializing a chroot (closes#472)
* Copy the Qemu binary into the forign-arch chroots
before initializing them, so the post-install script
directly work during the chroot setup and we don't need
to call apk fix afterwards
* Use pmb.helpers.repo.update(), which only updates the
APKINDEX files if they are older than 4 hours, instead
of using apk's repo update function which always
downloads the APKINDEX files
* Chroot initialization
* Getting the initial APKINDEX to download apk-tools-static
* Updating the APKINDEX at the start of pmbootstrap install
* Fixed a bug in from_chroot_suffix: the buildroot_x86_64 has
architecture x86_64, not x86.
* Don't ask for the mesa driver when the Qemu arch is not the
native arch and always use swrast in that case
* qemu-vexpress: use LTS kernel
* qemu-aarch64: use drm-backend for weston
Thanks to Pablo Castellano and Martijn Braam!
In postmarketOS we are now able to generate system images with the
correct configuration so that they can boot already using qemu
This commit brings the `pmbootstrap qemu` action.
This command is very handy because you don't have to set all the
qemu parameters, pmbootstrap does it for you.
* device-qemu-vexpress: Added kernel command line according to wiki
* qemu: Added workaround for image writing permissions
* qemu: Added support to launch postmarketOS in a QEMU virtual machine
- Support for emulating these architectures in QEMU: arm, aarch64, x86_84
- Generate QEMU command correctly depending no guest architecture (arm/x86)
- Run QEMU in the same architecture as the host by default
- Refactoring in pmb.parse.arch and pmb.qemu.run
- Raise exception if DTB file or system image are not present
- Display more useful information when something fails (e.g. image not found)
- Run qemu version depending on arch (host or argument), not device configured
* device-qemu-amd64: set deviceinfo_kernel_cmdline to "PMOS_NO_OUTPUT_REDIRECT"
* qemu: added --memory argument to specific guest RAM
* device-qemu-amd64: adjusted deviceinfo_kernel_cmdline (console=tty1)
* Added /etc/network/interfaces for qemu-amd64
* qemu: Added KVM support if /dev/kvm if present
* Specify separate machines for architecture
* qemu: Check if QEMU is installed instead of crashing
* Added graphics driver to qemu-aarch64
- Use arm (as used in qemu) instead of armhf (used in Alpine)
- qemu argument is -dtb
- Follow same style to build the command + arguments
* qemu: Added SSH port redirection: ./pmbootstrap.py qemu -p 2222
* Quote architecture in logging message for easier reading
* Added shortcut arguments for --rootfs, --buildroot and --suffix
* Simply remove beforehand link to nowhere if exists (fix#278)
Fixed crash when symlink already existed but pointed to a non-existing location
* Fix hardcoded `armhf` in pmb/aportgen/binutils.py
* Generate aports: `binutils-aarch64`, `musl-aarch64`, `gcc-aarch64`
* Distccd: Remember the cross-compiler architecture (currently armhf
or aarch64), that the current distccd is running as, and restart
distccd with the correct architecture, in case a different arch
is needed than what it is currently running as. (Depending on the
cross-compiler arch, the PATH variable gets adjusted before
starting distccd)
* Testcases: add aport generation for aarch64, add cross-compiling
to aarch64
* pmb/parse/arch.py: Add aarch64 to the mapping
