[Xen-devel] Is there anybody trying Xen VT-d on X48 chipset?
hi, I am trying Xen unstable tip on X48 motherboard but I got a xen BUG in xen/drivers/passthrough/vtd/iommu.c:496. Can anybody take a look at this problem? BTW, I don''t know how to collect the log so just take a picture by cell phone. Can you show me how to collect the log also? It looks that I can''t send message with attachment to the mailing list? Currently, what I have is just the screenshot of the BUG. Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven''t the technology we are using! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Neo, Can you please apply the following patch and send the log and your BIOS information back? You can setup a serial port to collect the debug information. Thanks. diff -r d434a7dfe02d xen/drivers/passthrough/vtd/dmar.c --- a/xen/drivers/passthrough/vtd/dmar.c Fri Jun 27 13:40:21 2008 +0800 +++ b/xen/drivers/passthrough/vtd/dmar.c Sun Jun 29 21:07:00 2008 +0800 @@ -423,6 +423,9 @@ acpi_parse_one_rmrr(struct acpi_dmar_ent return -ENOMEM; memset(rmrru, 0, sizeof(struct acpi_rmrr_unit)); + printk("+++ acpi_parse_one_rmrr: %lx, %lx\n", + rmrr->base_address, rmrr->end_address); + rmrru->base_address = rmrr->base_address; rmrru->end_address = rmrr->end_address; dev_scope_start = (void *)(rmrr + 1);>-----Original Message----- >From: xen-devel-bounces@lists.xensource.com >[mailto:xen-devel-bounces@lists.xensource.com] On Behalf Of Neo Jia >Sent: Sunday, June 29, 2008 6:49 AM >To: xen-devel@lists.xensource.com; xen-users@lists.xensource.com >Subject: [Xen-devel] Is there anybody trying Xen VT-d on X48 chipset? > >hi, > >I am trying Xen unstable tip on X48 motherboard but I got a xen BUG in >xen/drivers/passthrough/vtd/iommu.c:496. > >Can anybody take a look at this problem? > >BTW, I don''t know how to collect the log so just take a picture by >cell phone.
