[Qemu-devel] [BUG] BSOD on Win2003 Server when 64bit PCI resource is present

[Qemu-devel] [BUG] BSOD on Win2003 Server when 64bit PCI resource is present

[Alexey Korolev]

HI,

Current version of Seabios is causing blue screen on Windows2003 when 64bit PCI resource is present and occupies high memory.

BSOD Error code is: 0x000000A5 (0x02, 0xFFFFfADF6A446880, 0x1, 0xFFFFFADFAA34690)

The issue is localized, it is related to presence of 64bit resource in _CRS method.

If we disable a 64bit region from _CRS  the Win2003 load normally but this doesn't allow Windows to use 64bit resources.

At the moment I have no idea how to fix this. Please help! 

P/S 
Yet another issue is related to debug messages.
If I add any DBUG call in acpi-dst it will cause BSOD on win2003 (win2008 works fine)

Unfortunately, it's very difficult to debug acpi issues on Windows.
Gerd's been on vacation this week - so, lets give him a chance to look
at it when he gets back.  If it can't be resolved, we'll need to
revert the patch that broke Win2003.

I've seen this as well (on WinXP - I don't have Win2003).
Unfortunately, I haven't been able to find out why the debug macro
fails on these older versions of Windows.

Thank you for your reply.
Right - acpi issues are painful. Actually I'm on a long holidays too. I'll do my best if you or Gerd need any help with the issue.

Kind regards,
Alexey

You can try inlining it (in practice this means adding simple
Store(0x41, DBGB) here and there).

I wonder if Windows 2003 does not support ConcatenateResTemplate.  The patch below
is obviously wrong, but should let you check if this is the issue:

Well, it isn't a regression, so no need to revert IMHO.

It breaks on winxp / win2k3 only in case 64bit pci is actually used.
Which happens only in case we run out of address space below 4G.  This
is a setup which isn't supported at all with older seabios versions.

The very first patch revision had a static entry in the _CRS array
(before _CRS became a method) which didn't work with winxp too.  So we
ended up with the _CRS method which (beside updating the 32bit window)
adds the 64bit RessourceTemplate only in case we actually have 64bit pci
ressources, so we don't disturb existing setups with a new 64bit entry
they might not be able to handle.

I've never seen 64bit RessourceTemplate entries work with winxp, I fear
the winxp acpi code just can't handle 64bit RessourceTemplates ...

cheers,
  Gerd
