[PATCH][HAP][2/2] fix CR4 initialization when hap is on
This patch initializes VMCB CR4 and shadow CR4 with 0 when VMCB is being constructed under nested paging mode. It complies with recent reset_to_realmode change in hvmloader.

[PATCH] patch to support super page (2M) with EPT
Attached are the patches to support super page with EPT. We only support 2M size. And shadow may still work fine with 4K pages. The patches can be split into 3 parts. Apply order is as attached. tool.diff To allocate 2M physical contiguous memory in guest except the first 2M and the last 2M. The first 2M covers special memory, and Xen use the last few pages in guest memory to do special

LWP Interrupt Handler
I am adding interrupt support for LWP, whose spec is available at http://support.amd.com/us/Processor_TechDocs/43724.pdf. Basically OS can specify an interrupt vector in LWP_CFG MSR; the interrupt will be triggered when event buffer overflows. For HVM guests, I want to re-inject this interrupt back into the guest VM. Here is one idea similar to virtualized PMU: It first registers a special

Hardware Assisted Paging Param and Message
This patch changes hap parameter from boolean to integer. So users can disable and enable hap using "hap=0" and "hap=1". It also prints out nested paging message under SVM.

Question regarding the number of P2M l3e entries
In p2m.c (line 197 and line 550), the code assumes the number of L3 P2M table entries is 8 (under PAE mode). According to Intel and AMD specs, it is 4. Could someone explain this discrepancy? Is it a bug? -Wei _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

[PATCH] pciback: restore PCI BARs on D3->D0 transition
Ever since xen-unstable cset 14308 ("pci back: Fix registration of of filters on subsections of config space") I''ve been getting an MCA on the *2nd* boot of a driver domain using an e1000 NIC. Cset 14308 allowed the proper setup of the PM control registers, so the NIC is put in the D3 power state when the driver domain shuts down. Unfortunately, pci_set_power_state()

The attached file is the super page patch which supports both 2MB and 4MB (depending on the paging modes of hypervisor) under hardware assisted paging. The idea is to allocate super pages when guests are being created. Whenever such requests cannot be satisfied, it falls back to normal 4KB allocation. Also it splits large pages into normal 4KB pages whenever necessary. This patch is applicable on
