[PATCH] A fix for CR8 acceleration on 64bit guest
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

score test for logistic regression
Dear R experts, I'm trying to find a code to calculate the p-value from the score test for the logistic regression. My fit is like this: logit=beta0+beta1*x1+beta2*x2 +....+ betak* xk. And my H0 is beta1=beta2=...=betak =0. Any help will be highly appreciated. Thank you! Ying

[PATCH 5/5] SVM: Clear VMCB''s EFER.LME when guest disables paging
[SVM] Clear VMCB''s EFER.LME when guest disables paging Since the guest''s CR0.PG is always set (in shadow paging), EFER.LME must be cleared along with EFER.LMA when the guest is disabling paging.

[HVM][SVM][PATCH][1/2] VINTR intercept signal
These two patches affect the interrupt injection logic for AMD-V (only). These patches fix issues with Windows HVM guests during boot menu screen: 1) the timer countdown is no longer very slow 2) kbd response is now no longer slow or non-existent We have also seen an occasional "dma lost interrupt"/expiry errors, and these patches seem to help with these, especially with SUSE10 HVM

[HVM][SVM][PATCH][2/2] Delay ExtInt Injection
Patch 2/2 - Add flag to indicate that an exception event needs injecting, and to delay the ext interrupt injection. Remove unnecessary check of RFLAGS.IF for ExtInt injection. Applies cleanly to xen-unstable c/s 11831. Please apply to xen-unstable.hg. We would also want this patch to be in a 3.0.3-1 base whenever that is branched.

Re: Xen-devel Digest, Vol 52, Issue 178
Hi, all I want to reduce the checkpoint size of a VM by memory exclusion. I try to find out all the free pages by reference count at VMM-level, As they declared that: /* Page is on a free list: ((count_info & PGC_count_mask) == 0). */ , in struct page_info which is defined in /xen/include/asm-x86/mm.h, but unfortunately, all the pages in a idle VM accords with this condition.

[PATCH] Fix write parameter masking for 32-bit guests.
Changeset 15046:e527b4ff1948 breaks 32-bit HVM guest: when req->size is 4, "1UL << 32" returns 1 in IA32 system, so the mask becomes 0 wrongly. The attached patch fixes this by using 64-bit left-shift.

RE: A question on vmx loader in xen - how and when rombiosis loaded into memory
Thank you. I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems? I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

[Patch] Add VMX memory-mapped Local APIC access optimization
Some operating systems access the local APIC TPR very frequently, and we handle that using software-based local APIC virtualization in Xen today. Such virtualization incurs a number of VM exits from the memory-access instructions against the APIC page in the guest. The attached patch enables the TPR shadow feature that provides APIC TPR virtualization in hardware. Our tests indicate it can
