Hi, John Can you try the attached patch ? This issue can be reproduced on SMP platform, while the domain 0 is UP. The reason is, after finishing a dma request, the dma thread will trigger the interrupt and then clear the call back function. When guest get the interrupt , it will try to check the call back function, if it is set, then it will trigger a dma request again. So if the checking for

The patch enables x86_32 PAE unmodified guests on 64-bit Xen when the hvm feature is present. We tested only Linux at this point, and we''ll improve the functionality as we test other guests. The SVM needs the equivalent changes to the vmc.c to get this functionality working, but this patch does not break the build. Signed-off-by: Jun Nakajima <jun.nakajima@intel.com>

Currently the vector is not freed for MSI interrupt, the three patches fix the issue. The first patch(pirq.patch) move the get_free_pirq/map(unmap)_domain_pirq from arch/x86/physdev.c to arch/x86/irq.c, since that should be part of irq managment, no logic changes. The second patch(msi_vector_clean.patch) free the vector when the pirq is unmapped or when domain destroy. One thing need notice for

Propagate guest MSR writes to machine MSRs immediately Right now, we have an exposure between the time the MSR is written and used by an instruction such as syscall. If there is a context switch and we do vmx_do_restore_msrs(), everything goes fine. But if we don''t, then we execute the syscall with the wrong MSR.

This patch clean up VMX builder. Since now we have vmxloader, old code loading linux kernel directly is not needed. 1. remove linux parameters. 2. remove init ramdisk. 3. remove e820 memmap config file parse. Also e820 map handling code is changed in vmx_setup_platform. 4. remove provisional GDT, and construct_init_guest_vmcs is updated greatly. 5. remove some ugly tailing space. Thanks Keir for

Hi, Keir, These patches are rebased version of Yunhong''s original patches, which were sent out before XEN 3.2 was released. These patches enable MSI support and limited MSI-X support in XEN. Here is the original description of the patches from Yunhong''s mail. The basic idea including: 1) Keep vector global resource owned by xen, while split pirq into per-domain
