[PATCH 0/5] Enable bus master support for rtl8139 network cards on Apple PPC machines
by Mark Cave-Ayland 07 Aug '16

07 Aug '16

This patchset is loosely based on earlier work by BALATON Zoltan <balaton(a)eik.bme.hu> and provides basic infrastructure to allow OpenBIOS to enable PCI device bus mastering. Following on from discussions on the QEMU mailing list, it seems that Apple's OF enables bus mastering for some PCI devices by default, and as a result some buggy drivers forget to explicitly enable it and hence these devices fail under QEMU's emulation. The first 3 patches add the basic support routines while the last 2 patches enable bus mastering for the rtl8139 card on Apple PPC machines which is required for OS X and MorphOS.

[PATCH] ppc: force target CPU
by Laurent Vivier 02 Feb '16

With gcc-5.2 default target is power7. As openbios targets PowerMacs G3/G4/G5, force gcc target to be G3 (32bit) or G5 (64bit).

If you're trying to override DESTDIR then you'd already need something that executes "make DESTDIR=/path/to/destdir" so if this works as Segher suggests then can you not do "make DESTDIR=$DESTDIR" or similar? ATB, Mark.

[PATCH 1/1] [FCODE-utils] Allow overriding more Makefile vars
by Peter Lemenkov 18 Jan '16

18 Jan '16

As a package maintainer I'd like to override some more Makefile variables. Namely: * DESTDIR * strip command invokation (ability to suppress it by passing /bin/true instead of /bin/strip) * pass custom gcc flags This patch allows this. It does not break any existing workflows where it's not required to change these variables.

Progress on Sparc64?
by Nick Couchman 17 Jan '16

17 Jan '16

Wondering if there have been any recent developments getting OpenBIOS + Qemu working for the Sparc64 platform? I have a couple of legacy applications that require 64-bit Sparc support that would nice to have running on here. Anything I can do to help debug issues? I have ISOs for 64-bit Solaris 8, 9, 10, and 11, and am happy to test stuff out. -Nick == This e-mail may contain SEAKR Engineering (SEAKR) Confidential and Proprietary Information.

Below are some of the results that I'm seeing trying to boot various versions of Solaris on the qemu-system-sparc64 platform. Let me know if there is other debugging info that would be useful - different qemu switches, gdb output, and/or Solaris boot parameters. ==Solaris 8 64-bit on Sparc64== [root@qemu ~]# !68 /opt/qemu/bin/qemu-system-sparc64 -nographic -cdrom /root/sol-8-hw4-install-sparc.iso -boot d -m 2048M OpenBIOS for Sparc64 Configuration device id QEMU version 1 machine id 0 kernel cmdline CPUs: 1 x SUNW,UltraSPARC-IIi UUID: 00000000-0000-0000-0000-000000000000 Welcome to OpenBIOS v1.1 built on Oct 27 2015 23:43 Type 'help' for detailed information Trying cdrom:f...

Author: mcayland Date: Fri Jan 8 13:09:48 2016 New Revision: 1377 URL: http://tracker.coreboot.org/trac/openbios/changeset/1377 Log: pci: don't hard-code PCI interrupt maps by default The current code for openpic interrupts is incorrect for two reasons: firstly it generates an interrupt-map property with 8 IRQ pins (when only 4 are specified and so the last 4 entries are junk), and secondly it hard-codes the entries with a non-standard interrupt-mask to give one entry per pin rather than one entry per PCI device. Switch everything over to use the existing code used by SPARC64 which dynamically enumerates the child nodes and builds up the correct properties on demand. This ensures that everything will work on PCI platforms particularly if extra cards are dynamically plugged into QEMU.
