[Qemu-devel] [PATCHv3 0/2] sun4m: Implement Sun CG3 framebuffer for QEMU |

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:

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.
v3:
- Rebased to git master
- Fix DEBUG_CG3 macro
- Use register constants based upon Linux/BSD drivers
- Use qemu_log(LOG_UNIMP ... ) to capture unrecognised register accesses
- Rename device type from SUNW,cgthree to cgthree (matches OBP)
- Use error_report() instead of fprintf(stderr ... )
- Convert from init to realizefn
v2:
- Rebased to git master
- Updated QEMU,cgthree.bin ROM to latest OpenBIOS version
- Added Peter Maydell to CC
