Hello Gennady!
Wasn''t planning on posting the patch until it works. Also not sure
if it''ll end up destroying stuff so, do take care! Not my fault if
unfortunate stuff happens!
The patch was hastily created on a separate Ubuntu machine with
the source partition mounted, so I couldn''t do a compile test nor am I
sure if all the changes I made are in the patch. Tell me if it doesn''t
compile after applying the patch, I probably missed a file or two.
Patch is based on the original VGA passthrough patches posted by
Weidong, modified to account for the ROMBIOS code being moved to its
own file. It includes the claim cycle patch for secondary graphics
card passthrough as well.
Remember to place your graphics card''s firmware into
tools/firmware/vgabios/ after each "make clean".
Regards,
Liwei

Hello again Liwei! Thanks for your patch it applied good :) With your patch I can run my ATI 5450 as primary GPU (I have no secondary at all) as basic VGA: Windows XP can start and show the desktop if it has no installed drivers. It is very big progress for me :) After I installed drivers it can''t init the GPU. I think when you tries to install Win7 you got same - because it already have buildin drivers and tries to init extended display mode. My logs is: root@xen:/var/log/xen# tail -f /var/log/xen/qemu-dm-winxp.log (here domU started up) pt_iomem_map: e_phys=d0000000 maddr=d0000000 type=8 len=268435456 index=0 first_map=1 pt_bar_reg_read: first read BARs of gfx pt_bar_reg_read: first read BARs of gfx pt_iomem_map: e_phys=febc0000 maddr=febc0000 type=0 len=131072 index=2 first_map=1 pt_bar_reg_read: first read BARs of gfx pt_bar_reg_read: first read BARs of gfx pt_ioport_map: e_phys=e000 pio_base=e000 len=256 index=4 first_map=1 pt_iomem_map: e_phys=f1000000 maddr=febfc000 type=0 len=16384 index=0 first_map=1 platform_fixed_ioport: changed ro/rw state of ROM memory area. now is rw state. platform_fixed_ioport: changed ro/rw state of ROM memory area. now is ro state.

I have HD6850 as primary VGA and I was able to install Windows XP and 7 with AMD drivers without problem. I just was not able to see early parts of boot. This patch breaks boot of the virtual system completely. -- Pavel Mateja _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I was looking for ways to load VGA BIOS into virtual machine and two of them showed up. FIrst is in your patch. Second is to load VGA BIOS from disk in pt-graphics.c function get_vgabios. You way seems to be much mor complicated. What''s the gain there? What is the gfx_first_read_BAR array good for? You just thow away first read of every BAR there. -- Pavel Mateja _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
(I''m still unsure which list to post to, so I''m cross posting
again.
Prehaps someone can recommend me which list to stick to?)
Hey,
Just to tell you I''ve read your email and will keep you updated
when I get down to trying again. Currently the computer I''m trying to
passthrough on is my work computer, so it takes some motivation for me
to reboot it into xen. =)
Meanwhile, you can check out these two email snippets I''ve
collected over the week (I''ve lost their sources, but they''re
part of
the threads pointed to in the VGAPassthrough wiki page).
----------------------------------------
(This one shows how to properly reserve the memory ranges)
----------------------------------------
I forgot to mention that you should change memory addresses in
xen-vBAR-pBAR.patch according to your MMIO BARs of your assigned gfx
card.
For example, the output of ''lspci -s 01:00.0 -v'':
01:00.0 VGA compatible controller: nVidia Corporation Unknown
device 05ff (rev a1) (prog-if 00 [VGA controller])
Subsystem: nVidia Corporation Unknown device 0661
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at c2000000 (32-bit, non-prefetchable) [size=16M]
Memory at e0000000 (64-bit, prefetchable) [size=256M]
Memory at c0000000 (64-bit, non-prefetchable) [size=32M]
I/O ports at 9c00 [size=128]
Expansion ROM at bff00000 [disabled] [size=512K]
Capabilities: [60] Power Management version 3
Capabilities: [68] Message Signalled Interrupts: 64bit+
Queue=0/0 Enable+
Capabilities: [78] Express Endpoint IRQ 0
you can see I reserve above memories in dsdt.asl in
xen-vBAR-pBAR.patch. you should replace them with memories of your
gfx.
----------------------------------------
----------------------------------------
(I''m having a problem similar to this one. My VGA ROM is actually
bigger than what xen allocated. I recall the first VGA passthrough
patch manually modified the range, so I''d try that. You might want to
check if your ROM size is larger than xen can handle too.)
----------------------------------------
I suspect your vga bios file is incorrect, its size is very small. I found
following VGA bios in xm_dmesg.log: ... (XEN) HVM1: BIOS map: (XEN)
HVM1: c0000-c07ff: VGA BIOS ...
You can check if the VGA bios is really loaded. You can use ''xxd
vgabios-pt.bin''
to see the VGA bios content, of course you can see the size. After you apply the
patches I posted and mak the code, you can see vgabios_pt[] in
xen-unstable.hg/tools/firmware/hvmloader/roms.h. content of vgabios_pt[] should
be the same with output of ''xxd vgabios-pt.bin''.
----------------------------------------
Do keep everyone updated on the Xen list.
