similar to: [PATCH] Substitue the duplicate spin_lock_irqsave to spin_lock in the vt-d code path

Keir, It''s a resending patch for the timeout mechanism to deal with the shared interrupt issue for vt-d enabled hvm guest. We modify the patch following your comments last time and make some other small fix: 1) We don''t touch the locking around the hvm_dpci_eoi(). 2) Remove the HZ from the TIME_OUT_PERIOD macro which may confuse others. 3) Add some

From: Julia Lawall <julia@diku.dk> If spin_lock_irqsave is called twice in a row with the same second argument, the interrupt state at the point of the second call overwrites the value saved by the first call. Indeed, the second call does not need to save the interrupt state, so it is changed to a simple spin_lock. The semantic match that finds this problem is as follows:

The patch attached is to set effective memory type for EPT according to the VT-d snoop control capability, and also includes some cleansup for EPT & VT-d both enabled.

Attached is a patch for shared interrupt between dom0 and HVM domain for vtd. Most of problem is caused by that we should inject interrupt to both domains and the physical interrupt deassertion then may be delayed by the device assigned to the HVM. The patch adds a timer, and the time out value is sufficient large to tolerant the delaying used to wait for the physical interrupt deassertion.

Ian, Keir, This patch is to boot 32-bit VMX guest on the 64-bit host. Double-compile is used to make both 64-bit guest and 32-bit guest can work, the shadow page-table uses current 64-bit shadow code''s structure to simulate 32-bit guest''s 2-level page-table.

The patch deals with the situation which guest OS uses unused page table pages as data pages and write data to them. The pages will still be grabbed by Xen as page table pages, and lots of unnecessary page faults occur. The patch will check if the data guest writes to the page table contains valid mfn or not, if not, we believe it is a data page now and then unshadow the page. The patch

This patch is a small fix for CR8 acceleration on 64bit guest. For current CR8 acceleration, we do not call update_tpr_threshold() at every VMEXIT. But at some situations, we cannot inject guest interrupts in time. And at some critical time, it will bring up a blue screen to 64bit Windows guest. Try this scenario: 1) At one VMIT, tpr = TPR_THRESHOLD, but tpr < pending IRQ, and we

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>

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.

The first 2M covers special memory, and Xen use the last few pages in guest memory to do special

However how is this field used to substitute replacement dial extensions... in other words as an example, lets say my EXTEN as passed to and back from the rate_engine is 01144123456789 and I want to have a

Hi, I wanted to implemente WFQ, but it is not implemented on tc. Is there any way of making something like WFQ with which is implemented on tc?? What I exactly want to do, is to select flows by IP and port destination, and priorize them, but I don''t need (and don''t really want) to fix any rate... Has anyone got any clue??? Thank you Bye

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

Detect invalid/unsupported configurations in iommu_alloc() - offsets read from hardware must not lead to exceeding a single page (since only that much gets mapped). This covers the apparently not uncommon case of the address pointed to by a DMAR reading as all ones (Linux for example also checks for this). Further correct error handling of that function: Without storing the allocated "struct
