This patchset provides QEMU with an implementation of the Sun CG3 8-bit framebuffer. It is based upon Bob Breuer's original work which has been rebased onto git master, and is now capable of running with an OpenBIOS CG3 FCode ROM instead of requiring copies of proprietary Sun ROMs.
The motivation behind this patch is that older operating systems such as Debian Woody and Solaris (running OpenWindows) do not contain drivers for the TCX framebuffer and as a result currently cannot run in graphical mode. The screenshots linked below show qemu-system-sparc successfully running both Debian Woody and the Solaris 8 installer in graphical mode during testing: http://www.ilande.co.uk/tmp/debian-woody.png http://www.ilande.co.uk/tmp/sol8-1.png http://www.ilande.co.uk/tmp/sol8-2.png The CG3 framebuffer is selected by passing -vga cg3 on the command line to qemu-system-sparc. If either -vga tcx is specified (or the -vga argument is omitted) then qemu-system-sparc defaults to using the existing TCX framebuffer to maintain compatibility. v2: - Rebased to git master - Updated QEMU,cgthree.bin ROM to latest OpenBIOS version - Added Peter Maydell to CC Mark Cave-Ayland (2): sun4m: Add Sun CG3 framebuffer and corresponding OpenBIOS FCode ROM sun4m: Add Sun CG3 framebuffer initialisation function Makefile | 2 +- default-configs/sparc-softmmu.mak | 1 + hw/display/Makefile.objs | 1 + hw/display/cg3.c | 358 +++++++++++++++++++++++++++++++++++++ hw/sparc/sun4m.c | 60 ++++++- include/sysemu/sysemu.h | 1 + pc-bios/QEMU,cgthree.bin | Bin 0 -> 850 bytes pc-bios/README | 4 +- vl.c | 24 +++ 9 files changed, 446 insertions(+), 5 deletions(-) create mode 100644 hw/display/cg3.c create mode 100644 pc-bios/QEMU,cgthree.bin -- 1.7.10.4
