[Xen-devel] Using VGA PT for nVidia, causes weird "*** int 15h function AX=5f14, BX=078f not yet supported!" messages to appear in qemu log file
Hi, When i''m doing nVidia PT, (using all the steps described earlier in this mailing list), i start to see starnge messages in the qemu log file, which says: " ... *** int 15h function AX=5f14, BX=078f not yet supported! ... " Here is the end of my qemu log file: " .... ACPI PCI hotplug: read addr=0x1140, val=0x00. ACPI PCI hotplug: read addr=0x1140, val=0x00. ACPI PCI hotplug: read addr=0x1141, val=0x00. ACPI PCI hotplug: read addr=0x1141, val=0x00. *** int 15h function AX=5f14, BX=078f not yet supported! *** int 15h function AX=5f14, BX=078f not yet supported! *** int 15h function AX=5f14, BX=078f not yet supported! *** int 15h function AX=5f14, BX=078f not yet supported! *** int 15h function AX=5f14, BX=078f not yet supported! *** int 15h function AX=5f14, BX=078f not yet supported!

" When i search the problem, i found similar messages in the qemu log file, of other people which used the nVidia PT. For example: http://lists.xensource.com/archives/html/xen-devel/2009-09/msg00285.html http://article.gmane.org/gmane.comp.emulators.xen.devel/70827 Does anyone know why these messages appear, and what is the meaning of them? Does it signal that there is a bug somewhere in the code? Tom _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I think they are harmless debug messages. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

They are only during guest boot, and they stop appearing. Do u have any idea why they appear? Is it somehow related to the vga BIOS?

I think the vga BIO Shas a debug port it can write to that makes messages appear in qemu''s log. It''ll print a warning if an unsupported BIOS call is attempted (it''s not always a problem if a BIOS call isn''t supported). The ACPI hotplug messages are just informational, and come from qemu itself. -- Keir On 20/10/2009 14:35, "Tom Rotenberg" <tom.rotenberg@gmail.com> wrote:> They are only during guest boot, and they stop appearing. > Do u have any idea why they appear?

Hi, I am inclined to think that this is a harmless debug message. My Windows XP Home Edition virtual machine seems to be rather stable. I could play 3D accelerated FPS games in Xen-based Windows virtual machines without issues. See http://www.youtube.com/watch?v=5tLzYqIJ7Q0 Both USB optical mouse and USB keyboard have been passed through to Win XP domU. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore Blog URL: http://teo-en-ming-aka-zhang-enming.blogspot.com Email: space.time.universe@gmail.com MSN: teoenming@hotmail.com Mobile Phone: +65-9648-9798 Street: Bedok Reservoir Road Republic of Singapore On Tue, Oct 20, 2009 at 9:26 PM, Keir Fraser <keir.fraser@eu.citrix.com> wrote:> On 20/10/2009 13:18, "Tom Rotenberg" <tom.rotenberg@gmail.com> wrote: > >> When i search the problem, i found similar messages in the qemu log >> file, of other people which used the nVidia PT.
