In this case it is /pci/mac-io/ide@1000/@0:9. Yes, but I don't see where Mac OS X has this hardcoded. It gets passed in somehow. What machine type is this? g3beige? On there, I don't see an ide1 alias anywhere: 0 > dev /aliases ok 0 > ls ok 0 > .properties name "aliases" screen "/pci@80000000/mac-io@3/escc/ch-b" mac-io "/pci@80000000/mac-io@3" via-cuda "/pci@80000000/mac-io@3/via-cuda" adb-keyboard "/pci@80000000/mac-io@3/via-cuda/adb/keyboard" adb-mouse "/pci@80000000/mac-io@3/via-cuda/adb/mouse" rtc "/pci@80000000/mac-io@3/via-cuda/rtc" nvram "/pci@80000000/mac-io@3/nvram" ttya "/pci@80000000/mac-io@3/escc/ch-a" scca "/pci@80000000/mac-io@3/escc/ch-a" ttyb "/pci@80000000/mac-io@3/escc/ch-b" sccb "/pci@80000000/mac-io@3/escc/ch-b" ide0 "/pci@80000000/pci-ata@4/ata-2/cdrom" cd "/pci@80000000/pci-ata@4/ata-2/cdrom" cdrom "/pci@80000000/pci-ata@4/ata-2/cdrom" keyboard "/pci@80000000/mac-io@3/via-cuda@16000/adb/keyboard@8" ok Somehow Mac OS resolves "ide1" into "/pci/mac-io/ide@1000".

[PATCH 0/4] Switch TCX/VGA drivers from Forth to FCode
by Mark Cave-Ayland 24 Jun '13

24 Jun '13

Note: this patchset should be applied on top of my last display patchset here: http://www.openfirmware.info/pipermail/openbios/2013-June/007753.html. At the moment the IEEE1275 initialisers for TCX/VGA are setup by calling is-install directly; in actual fact what we need to do is convert the drivers over to FCode and execute them during a bus probe. This patchset switches the tcx.fs and vga.fs drivers over to FCode from Forth, includes the FCode binaries as part of the OpenBIOS image, and executes the drivers using byte-load during probe. Currently both drivers are reasonably bare (with most of the work still being done in C), however it is a starting point for moving more functionality into the FCode drivers and makes it possible to implement a "probe-self" word in the near future. This patch shouldn't alter any functionality, but the most significant change is that it does introduce "toke" from the OpenFirmware fcode-utils suite as a mandatory dependency for building OpenBIOS. Mark Cave-Ayland (4): switch-arch: make the fcode-utils tokeniser "toke" mandatory for the build config: add new fcode tag and support for building Fcode into dictionaries SPARC32: switch TCX driver over to FCode x86/SPARC64/PPC/amd64: switch VGA driver over to FCode openbios-devel/Makefile.target | 3 ++ openbios-devel/arch/amd64/build.xml | 1 + openbios-devel/arch/amd64/init.fs | 7 ++++ openbios-devel/arch/ppc/build.xml | 5 +++ openbios-devel/arch/ppc/ppc.fs | 11 ++++++ openbios-devel/arch/sparc32/build.xml | 1 + openbios-devel/arch/sparc32/init.fs | 6 +++ openbios-devel/arch/sparc32/tree.fs | 1 + openbios-devel/arch/sparc64/build.xml | 1 + openbios-devel/arch/sparc64/init.fs | 6 +++ openbios-devel/arch/sparc64/tree.fs | 2 + openbios-devel/arch/x86/build.xml | 1 + openbios-devel/arch/x86/init.fs | 8 ++++ openbios-devel/config/examples/amd64_config.xml | 1 + openbios-devel/config/scripts/switch-arch | 12 ++++++ openbios-devel/config/xml/dictionary.xsl | 40 ++++++++++++++++--- openbios-devel/config/xml/fcode.xsl | 48 +++++++++++++++++++++++ openbios-devel/config/xml/makefile.xsl | 2 + openbios-devel/config/xml/rules.xml | 3 ++ openbios-devel/drivers/build.xml | 5 ++- openbios-devel/drivers/pci.c | 3 +- openbios-devel/drivers/sbus.c | 5 ++- openbios-devel/drivers/tcx.fs | 35 ++++++++++++++++- openbios-devel/drivers/vga.fs | 35 ++++++++++++++++- 24 files changed, 230 insertions(+), 12 deletions(-) create mode 100644 openbios-devel/config/xml/fcode.xsl -- 1.7.10.4

[PATCHv2 00/20] Switch to standards-compliant Forth console from C console
by Mark Cave-Ayland 22 Jun '13

22 Jun '13

As mentioned previously on-list, OpenBIOS currently contains two consoles - a C based console and a Forth based console. The Forth based console is currently broken, but is more feature complete than the C console, whilst also being more portable across different architectures. This patchset performs the following functions: - Fix various bugs in the Forth console - Optimise performance using low-level C graphics routines - Add simple IEEE1275-like initialisers for TCX and VGA graphics - Switch TCX and VGA drivers over to use the new console using the standard is-install word Once this patchset is committed, a further patchset will follow to remove all of the duplicate C console code, remove packages/video.c and unify the console input/routines into libopenbios. Changes since v1: - Rebase onto SVN trunk - Various minor bugfixes/tidy-ups - Fix CSI n;mH and CSI n;mf as reported by Blue Swirl - Implementation of remaining missing fb8-* defer words: fb8-insert-lines fb8-insert-characters fb8-delete-characters Mark Cave-Ayland (20): display.fs: Fix up default-font word. display.fs: Fix fb8-delete-lines within the inbuilt Forth terminal emulator. terminal.fs: Fix linefeeds on the bottom line of the Forth console. terminal.fs: Fix backspace sequence in Forth terminal. video: Create new video_common.c file for shared video primitive routines. video_common.c: Move primitive graphic operations into libopenbios/video_common.c. pci: Modify PCI display devices so that open and close words are not created automatically during initialisation. video: Create tcx.fs and vga.fs to simulate Fcode video initialisation code. display.fs: pass the colour depth and line bytes to the Forth terminal routines. video_common.c: create low-level video_mask_blit() function. video_common.c: create low-level video_invert_rect() function. display.fs: Fix fb8 routines to work with bit depths > 8. video_common.c: create low-level video_fill_rect() function. display.fs: optimise scrolling by copying/deleting multiple scanlines at once. display.fs: Add vertical font-spacing as per the existing C console implementation. terminal.fs: handle all cursor positioning within the terminal package. terminal.fs: Fix CSI n;mH and CSI n;mf control sequences. display.fs: add implementation of fb8-insert-lines. display.fs: add implementation of fb8-insert-characters and fb8-delete-characters. video: switch VGA and TCX drivers over to Forth console using is-install. openbios-devel/arch/sparc32/console.c | 12 - openbios-devel/arch/sparc32/openbios.c | 2 +- openbios-devel/drivers/build.xml | 2 + openbios-devel/drivers/pci.c | 14 +- openbios-devel/drivers/pci.h | 1 + openbios-devel/drivers/sbus.c | 2 + openbios-devel/drivers/tcx.fs | 13 + openbios-devel/drivers/vga.fs | 13 + openbios-devel/drivers/vga_vbe.c | 2 +- openbios-devel/forth/device/display.fs | 228 +++++++------- openbios-devel/forth/device/font.fs | 4 + openbios-devel/forth/device/terminal.fs | 67 +++- openbios-devel/include/libopenbios/video.h | 24 ++ openbios-devel/include/packages/video.h | 6 +- openbios-devel/libopenbios/build.xml | 1 + openbios-devel/libopenbios/console_common.c | 1 + openbios-devel/libopenbios/video_common.c | 446 +++++++++++++++++++++++++++ openbios-devel/packages/video.c | 279 +---------------- 18 files changed, 700 insertions(+), 417 deletions(-) create mode 100644 openbios-devel/drivers/tcx.fs create mode 100644 openbios-devel/drivers/vga.fs create mode 100644 openbios-devel/include/libopenbios/video.h create mode 100644 openbios-devel/libopenbios/video_common.c -- 1.7.10.4
