[PATCH v3] Limit binary dump bytes in .properties output
by BALATON Zoltan 26 Jan '23

26 Jan '23

Some device trees can contain large chunks of binary data that result in .properties output to get lost in the dump of all binary bytes. Put an upper limit of the bytes dumped.

CHRP booting.
by Jd Lyons 03 Oct '22

03 Oct '22

I’m trying to figure how Openbios boots CHRP boot scrips like :tbxi, yet SOLF does not. Can anyone point me to the code in Openbios that enables :tbxi/CHRP booting? Also, does anyone know how exactly that works, what was done to Openbios to enable booting the Mac OS? I’d really like to try and get Apple’s BootX to load on Qemu’s pseries machines and as I understand it CHRP booting should work in SLOF, but it just errors out on BootX with "bad executable”, so there must be some magic I need to understand about :tbxi CHRP boot scripts that SLOF needs some sort of patch.

[PATCH] Rename parse-hex to parse-1hex
by BALATON Zoltan 25 Sep '22

25 Sep '22

This word does not appear in OpenFirmware nor OpenBoot but Apple OF has a word called parse-1hex which is used by code running on that OF implementation. Rename parse-hex accordingly for compatibility.

[PATCH] Don't add open/close words to unmanaged devices
by BALATON Zoltan 25 Sep '22

25 Sep '22

Devices that OpenBIOS does not have a driver for may have an FCode driver that would create the open/close methods but this results in duplicate words due to the empty defaults OpenBIOS adds. These empty defaults are added so that open-dev works (which is needed to run an FCode driver) but to avoid this clash change open-dev to check if open method exists before calling it so we can omit the empty defaults and let an FCode driver install them without getting duplicates.

[PATCH 0/4] Add GitHub workflows to generate OpenBIOS binaries
by Mark Cave-Ayland 24 Feb '22

24 Feb '22

This is something I've been keen to do for some time which is to generate an OpenBIOS builder image with the required cross-compilers pre-installed, and then implement workflows so that a push to a branch or a versioned release tag will automatically create OpenBIOS binaries. One of the barriers to OpenBIOS development is getting the correct cross compilers installed: not just for the architecture being developed on, but also for all current supported architectures to ensure there are no regressions. Up until now I was unable to find a set of compilers that built working binaries across all architectures, but since Glenn pointed out the existence of the crosstool releases on kernel.org I've done some tests and confirmed that the cross compilers produce working binaries for all of SPARC32, SPARC64 and PPC. This series adds a manual action to create an openbios-builder image that is then integrated into automated workflows for building debug and release OpenBIOS binaries for all supported architectures (amd64, sparc32, sparc64, ppc and x86). The behaviour is currently very simple: - A push to a branch will build OpenBIOS binaries, and if it is the upstream openbios repository, generate a "latest" release - A push to a versioned release tag matching "v*" will build the OpenBIOS binaries and generate a versioned release For an example of how this will look when merged take a look at the release page of my OpenBIOS fork on GitHub at https://github.com/mcayland/openbios/releases. As a bonus once this has been merged and the openbios-builder image is pushed to ghcr.io it is possible to perform a local development build with simply: git clone https://github.com/openbios/openbios.git docker run --rm -it -v "$(pwd)/openbios:/root" ghcr.io/openbios/openbios-builder:master cd /root ./config/scripts/switch-arch sparc32 && make V=1 ... ... exit Signed-off-by: Mark Cave-Ayland <mark.cave-ayland(a)ilande.co.uk> Mark Cave-Ayland (4): docker: introduce Dockerfile.builder for openbios-builder container .github/workflows: add build-openbios-builder.yml action .github/workflows: add main.yml for building OpenBIOS upon push .github/workflows: add release.yml for generating an OpenBIOS release .github/workflows/build-openbios-builder.yml | 42 ++++++++ .github/workflows/main.yml | 103 +++++++++++++++++++ .github/workflows/release.yml | 101 ++++++++++++++++++ docker/Dockerfile.builder | 19 ++++ 4 files changed, 265 insertions(+) create mode 100644 .github/workflows/build-openbios-builder.yml create mode 100644 .github/workflows/main.yml create mode 100644 .github/workflows/release.yml create mode 100644 docker/Dockerfile.builder -- 2.20.1

Recent versions of GDB (and probably older ones too, but not checked) crash with and abort when loading the non-stripped 32-bit PPC QEMU build[1]. This is due to a bug in GDB on reading stab symbols. The only place in OpenBIOS where stab symbols are generated is in libgcc/crtsavres.S, which was copied from the linux kernel[2]. Symbols that were defined in the stabs section are still able to be seen in GDB after stabs removal. There does not appear to be a loss in debugging functionality.

The recent discussions about which architectures are currently supported has inspired me to revisit my work on adding GitHub workflow actions. Glenn pointed out that there are a couple of errors in the x86/amd64 builds which are fixed by this patchset. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland(a)ilande.co.uk> Mark Cave-Ayland (2): config/scripts/switch-arch: allow x86_64 prefix for x86 builds arch/unix/unix.c: fix build on x86 architecture with modern gcc compilers arch/unix/unix.c | 2 ++ config/scripts/switch-arch | 2 +- 2 files changed, 3 insertions(+), 1 deletion(-) -- 2.20.1
