To test, run "make menuconfig" select a build without xen, and run make. You'll see out/autoconf.h has DEBUG_IO_PORT=0x402. Then run "make menuconfig" select xen, and run make. You'll still see DEBUG_IO_PORT=0x402. You can look at VGA_VID in vgasrc/Kconfig for one possible solution to the above. -Kevin

[PATCH v2] Xen: Use VGA Hooks to make VGA passthrough work on certain devices
by Julian Pidancet 04 Feb '12

04 Feb '12

The Intel gfx VGA option ROM on certain platforms requires the 155f50 BIOS function to be implemented (even if it does nothing), to work properly. v2: Ignore the case where Option ROMs are pre-deployed. Make vgahook_setup independent of wether the CB* variables are set. VGA hooks can be enabled on non-coreboot and non-Xen configurations.

[PATCH 0/6] vgabios work
by Kevin O'Connor 04 Feb '12

04 Feb '12

More vgabios work. At the end of this series, the remaining bochsvga capabilities are now ported from the LGPL bios (with the exception of the 32bit interface which seems like it isn't worth porting). This basically completes the porting effort. -Kevin Kevin O'Connor (6): vgabios: Simplify cga/packed character screen writing. vgabios: Fix screen attrs on cga scroll. vgabios: Handle VGA option rom being re-run. vgabios: Add support for VBE get/set dac palette format (func 08). vgabios: Move save/restore state code from vgabios.c to stdvga.c. vgabios: Implement VBE save/restore state function (func 04). vgasrc/bochsvga.c | 89 +++++++++++++++++++++++++++++++++++++ vgasrc/bochsvga.h | 5 ++ vgasrc/clext.c | 43 +++++++++++++++--- vgasrc/clext.h | 3 + vgasrc/stdvga.c | 126 +++++++++++++++++++++++++++++++++++++++++++---------- vgasrc/stdvga.h | 32 ++----------- vgasrc/vbe.c | 57 ++++++++++++++++++++++-- vgasrc/vgabios.c | 111 ++++++++++++++++++----------------------------- vgasrc/vgabios.h | 5 ++- vgasrc/vgafb.c | 58 +++++++++--------------- vgasrc/vgahw.h | 36 +++++++++++++++ 11 files changed, 396 insertions(+), 169 deletions(-) -- 1.7.6.4

Can we do default 0xe9 if XEN default 0x0402 so this just comes out correctly depending on the other options selected? Ian.
