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

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).

[PATCH 0/8] SPARC64 Forth context rework
by Mark Cave-Ayland 29 Dec '15

29 Dec '15

This patchset is aimed at unifying the code used to preserve CPU context when switching from client programs into Forth, via either the CIF or interrupt handlers. It is part of a longer process to enable access to saved CPU context state from within Forth which will eventually enable proper implementation of the init-program and go words.

[PATCH] Add revision number to banner
by Programmingkid 04 Dec '15

04 Dec '15

The banner is displayed at the start of openbios with the version and build time. This patch adds the revision number for easier identification of binary version. It would look like this: Welcome to OpenBIOS v1.1 (Revision 1358) built on Nov 28 2015 18:22 If the user doesn't have the svn command or an svn repo, the word "unknown" is used instead of the number. signed-off-by: John Arbuckle <programmingkidx(a)gmail.com> Index: Makefile.target ============================================… [View More]

Hi Alfonso, Has there been any progress at all as to which extensions may be causing the crashes? ATB, Mark.

openbios cross compile fails with gcc 5.2

Hi all, openbios fails to build with gcc 5.2 cross compilers. This is using fedora 23 packages. There's a bug here with complete info: https://bugzilla.redhat.com/show_bug.cgi?id=1282890 The error is: powerpc64-linux-gnu-gcc $EXTRACFLAGS -m32 -msoft-float -fno-builtin-bcopy -fno-builtin-log2 -Os -g -DNATIVE_BITWIDTH_EQUALS_HOST_BITWIDTH -USWAP_ENDIANNESS -Wall -Wredundant-decls -Wshadow -Wpointer-arith -Wstrict-prototypes -Wmissing-declarations -Wundef -Wendif-labels -Wstrict-aliasing -… [View More]

CUDA has problems with Mac OS 10.4
by Programmingkid 20 Nov '15

20 Nov '15

I built Cormac O'Brien's QEMU repo for Mac OS 9 and tried to boot my Mac OS 10.4 boot cd. Mac OS 10.4's kernel panics because of a CUDA problem. I did use the mac99 target. Here is the error message: panic(cpu 0 caller 0x16E786CC): CUDA - TODO CHECK FOR TRANSACTION TYPE AND ERROR This is the command I used: ./ppc-softmmu/qemu-system-ppc -boot d -cdrom ~/tiger.iso -prom-env boot-args=-v -usb -M mac99 I think there is still something wrong with CUDA. But we might not have to "fix" it. When … [View More]we use the mac99 target, the PowerMac3,1 Macintosh system is what we are trying to emulate. My sources indicate that the PowerMac3,1 doesn't have a CUDA chip. This chip is used for ADB communications. Using it only on the BeigeG3 target makes sense. My sources for the PowerMac3,1 system is this link: http://www.everymac.com/systems/apple/powermac_g4/specs/powermac_g4_350_agp… and this device tree: PowerMac G4 device tree ff839ab8: /cpus ff839ce8: /PowerPC,G4@0 ff83a060: /l2-cache ff83ab58: /chosen ff83ace8: /memory@0 ff83af00: /openprom ff83b008: /client-services ff83c1a8: /rom@ff800000 ff83c330: /boot-rom@fff00000 ff83c4a8: /macos ff83c528: /options ff83c5a8: /aliases ff83cec8: /packages ff83cf30: /deblocker ff83d798: /disk-label ff83e198: /obp-tftp ff8439f0: /mac-parts ff844850: /mac-files ff847540: /hfs-plus-files ff84c1c8: /fat-files ff84def8: /iso-9660-files ff84eb00: /bootinfo-loader ff8507a0: /xcoff-loader ff8511b8: /pe-loader ff851b90: /elf-loader ff8531c0: /usb-hid-class ff8554d8: /usb-ms-class ff8576a8: /sbp2-disk ff858ac0: /ata-disk ff859cd8: /atapi-disk ff85b348: /bootpath-search ff861b68: /terminal-emulator ff861c00: /psuedo-hid ff861c88: /keyboard ff862308: /mouse ff862820: /multiboot ff86e7f0: /diagnostics ff86e858: /tools-node ff8704b8: /rtas ff8706b8: /nvram@fff04000 ff871180: /uni-n@f8000000 ff8713c8: /i2c@f8001000 ff871b10: /cereal ff8721c0: /pci@f0000000 ff898cd0: /uni-north-agp@b ff898f40: /ATY,Rage128Ps@10 ff873268: /pci@f2000000 ff8742d8: /pci-bridge@d ff876368: /mac-io@7 ff8773a0: /interrupt-controller@40000 ff877548: /gpio@50 ff877630: /extint-gpio1 ff8777c8: /programmer-switch ff877900: /escc-legacy@12000 ff877af8: /ch-a@12004 ff877c78: /ch-b@12000 ff877df8: /escc@13000 ff878000: /ch-a@13020 ff8789a8: /ch-b@13000 ff8792c0: /davbus@14000 ff879540: /sound ff879c40: /timer@15000 ff879da8: /via-pmu@16000 ff87ccf0: /rtc ff87d3e0: /power-mgt ff8bf378: /usb-power-mgt ff87d648: /i2c@18000 ff87ded8: /cereal ff87e5a0: /ata-4@1f000 ff880318: /disk ff8809e8: /ata-3@20000 ff882760: /disk ff882da8: /ata-3@21000 ff884b20: /disk ff8864c8: /ethernet@4 ff888690: /usb@8 ff88dd50: /usb@9 ff8be3f0: /hub@1 ff8be580: /keyboard@1 ff893410: /firewire@a ff8752e8: /pci@f4000000 ff8bb128: /ethernet@f [View Less]

[PATCH v2 0/4] Build openbios on powerpc64 host
by Laurent Vivier 06 Nov '15

06 Nov '15

This series of patches allows to build openbios on a powerpc64 host. It has been tested with the following targets: ppc, sparc32, sparc64. It has also been tested on x86_64 host with the same targets. v2: remove patches 3/5 and 4/5 of the first series and replace it with patch 4/4. We don't include the system includes using full pathname but use '-iquote' intead of '-I' A preliminary patch is needed for fcode-utils, as "toke" is broken on big endian architecture: diff -ru fcode-utils/… [View More]
