Dear Xen developers, David Techer and Others,
I am yet unable to passthrough my VGA adapter NVIDIA Geforce 8400 GS
to Windows XP Home Edition SP3 HVM domU. When Windows XP HVM is
started with XL, the monitor is BLANK. I am able to vnc into
into the VNC server for Win XP HVM domU 192.168.1.2:5901, where the
IP address is that of my dom0 eth0 interface. But doing a CTRL-ALT-1
and CTRL-ALT-2 on the QEMU console only show the words serial and
parallel console.
Please refer to the attached PDF file Xen VGA Passthrough - Version
1.0.pdf which I have written. All the patching, building,
installation, configuration files, and error logs in /var/log/xen
are provided in the PDF file which I have written. I hope the PDF
file can get through to xen-devel mailing list. It is only 88 kB.
Please do not say I have not submitted any meaningful and required
information required for troubleshooting. Please read my attached
PDF document. It is only 9 pages.
I want to ask whether the case of the following HEXADECIMAL values
matter.
/* reserve MMIO BARs of gfx for 1:1 mapping */
DWordMemory(
ResourceProducer, PosDecode, MinFixed, MaxFixed,
Cacheable, ReadWrite,
0x00000000,
0xD2000000,
0xD2FFFFFF,
0x00000000,
0x01000000)
DWordMemory(
ResourceProducer, PosDecode, MinFixed, MaxFixed,
NonCacheable, ReadWrite,
0x00000000,
0xC0000000,
0xCFFFFFFF,
0x00000000,
0x10000000)
DWordMemory(
ResourceProducer, PosDecode, MinFixed, MaxFixed,
Cacheable, ReadWrite,
0x00000000,
0xD0000000,
0xD1FFFFFF,
0x00000000,
0x02000000)
Does it matter if all the hex values are in lower case?
