[PATCH] ppc: force target CPU
by Laurent Vivier Feb. 2, 2016

Feb. 2, 2016

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 Dec. 29, 2015

Dec. 29, 2015

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 Dec. 4, 2015

Dec. 4, 2015

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 =================================================================== --- Makefile.target (revision 1358) +++ Makefile.target (working copy) @@ -52,11 +52,18 @@ versions: $(ODIR)/target/include/openbios-version.h $(ODIR)/forth/version.fs +# Set the REVISION variable to the current svn revision or to "unknown" +REVISION := $(shell svn info .. | grep "Revision: " | cut -c11-16) +ifeq ($(REVISION),) +REVISION = "unknown" +endif + $(ODIR)/forth/version.fs: $(call quiet-command,true, " GEN $(TARGET_DIR)$@") @DATE="$(shell echo `LC_ALL=C TZ=UTC date +'%b %e %Y %H:%M'`)" ; \ ( echo ": builddate \" $$DATE\" ; " ; \ - echo ": version \" $(VERSION)\" ; " ; ) \ + echo ": version \" $(VERSION)\" ; " ; \ + echo ": revision \" $(REVISION)\" ; " ; ) \ > $(dir $(a))/version.fs $(ODIR)/target/include/openbios-version.h: @@ -63,7 +70,8 @@ $(call quiet-command,true, " GEN $(TARGET_DIR)$@") @DATE="$(shell echo `LC_ALL=C TZ=UTC date +'%b %e %Y %H:%M'`)" ; \ ( echo "#define OPENBIOS_BUILD_DATE \"$$DATE\"" ; \ - echo "#define OPENBIOS_VERSION_STR \"$(VERSION)\"" ; ) \ + echo "#define OPENBIOS_VERSION_STR \"$(VERSION)\"" ; \ + echo "#define OPENBIOS_REVISION \"$(REVISION)\"" ; ) \ > $(dir $(a))/openbios-version.h info: Index: forth/admin/banner.fs =================================================================== --- forth/admin/banner.fs (revision 1358) +++ forth/admin/banner.fs (working copy) @@ -9,8 +9,8 @@ ; to builtin-logo :noname - builddate s" built on " version s" Welcome to OpenBIOS v" pocket - tmpstrcat tmpstrcat tmpstrcat drop + builddate s" ) built on " revision s" (Revision " version s" Welcome to OpenBIOS v" pocket + tmpstrcat tmpstrcat tmpstrcat tmpstrcat tmpstrcat drop ; to builtin-banner : suppress-banner ( -- )

A good starting point is the "Apple Audio Extension Module" since that seems to cause havoc on load. Do you know any good tutorials on how to debug an extension module on load i.e. how to step through its initialisation? Unfortunately there doesn't seem to be much related documentation around these days. ATB, Mark.

Yeah I noticed when booting from a CDROM that my open windows are remembered across sessions(!). This makes me think that OS 9 thinks the HFS volume is a HD rather than a CDROM and so mounts it read/write on boot.

I did get a backtrace once suggesting that it was trying to access digital CDROM audio which is why it crashed. Then again if it thinks that the CDROM is a HD then that's not going to help too much here either). ATB, Mark.

Hi all, openbios fails to build with gcc 5.2 cross compilers. This is using fedora 23 packages.

I'm clear on that but what I've meant was that we probably have to make a closer emulation of the real PowerMac (not one to one but close enough) to make OSes written for that hardware happy. I think we are missing some i2c and gpio emulation that these OSes might expect but I'm not sure. One thing that might help to hint at what's missing is to compile QEMU with DEBUG_UNASSIGNED (this will generate a lot of logs) and try to find out what is accessed that is not emulated.

CUDA has problems with Mac OS 10.4
by Programmingkid Nov. 20, 2015

Nov. 20, 2015

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 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

[PATCH v2 0/4] Build openbios on powerpc64 host
by Laurent Vivier Nov. 6, 2015

Nov. 6, 2015

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/toke/scanner.c fcode-utils-new/toke/scanner.c --- fcode-utils/toke/scanner.c 2006-10-30 09:48:28.000000000 +0100 +++ fcode-utils-new/toke/scanner.c 2015-10-19 00:21:43.417373690 +0200 @@ -1625,7 +1625,7 @@ void user_message( tic_param_t pfield ) { - char delim = (char)pfield.deflt_elem ; + char delim = (char)pfield.fw_token ; handle_user_message( delim, TRUE); } @@ -5295,7 +5295,7 @@ void process_remark( tic_param_t pfield ) { - char until_char = (char)pfield.deflt_elem ; + char until_char = (char)pfield.fw_token ; unsigned int start_lineno = lineno; #ifdef DEBUG_SCANNER Laurent Vivier (4): switch-arch: factorize code to compute architecture properties. switch-arch: compute base arch and allow native compiler for 32bit and 64bit. switch-arch: as for powerpc64, select sparc64 compiler to compile sparc32 bootstrap: don't include files from target/include as system includes.
