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
* Packaged libsparse
libsparse from the Android project provides multiple tools like img2simg
and simg2img.
These are used to split a large image for the system partition into
separate smaller chunks with sparse headers
This is required for several devices (at least bullhead, fp2 and titan)
because it fixes the "Invalid sparse file format at header magi" error
https://github.com/postmarketOS/pmbootstrap/issues/299
* Added new variable deviceinfo_flash_sparse (fixes#299)
Right after the system image is generated, pmbootstrap checks this
variable. In case it is true, run img2simg on it
* motorola-titan: enable deviceinfo_flash_sparse
* libsparse: use source from github: anestisb/android-simg2img
It is not that easy to use the upstream archive because everytime
you download it, the files have the current date as creation date
and that makes the file have a different checksum every download
