similar to: [PATCH][v5] PV extension of HVM(hybrid) in support in Xen

Hi Keir The latest (hybrid) patchset again... Change from v5: Address the comments from Tim. Change from v4: 1. Add support for PV clocksource on HVM. (Replace evtchn enabling with pv clock enabling). 2. Update the patch following Tim''s comments. Change from v3: 1. Minor polish the patchset. Replace several specific is_hvm_pv_evtchn_domain() judgement. 2. Name changed...

Implement tsc adjust feature IA32_TSC_ADJUST MSR is maintained separately for each logical processor. A logical processor maintains and uses the IA32_TSC_ADJUST MSR as follows: 1). On RESET, the value of the IA32_TSC_ADJUST MSR is 0; 2). If an execution of WRMSR to the IA32_TIME_STAMP_COUNTER MSR adds (or subtracts) value X from the TSC, the logical processor also adds (or subtracts) value X

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

Call update_domain_wallclock_time on hvm_latch_shinfo_size even if the bitness of the guest has already been set, this fixes the problem with the wallclock not being set for PVHVM guests on resume from migration.

Also, correct a copy&paste error in the documentation. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> --- This patch has been in the XenServer patch queue for a long time. It is more for debugging purposes than anything else, but is still proving to be valuable for tracking down bugs with HVM paging operations. diff -r 5af4f2ab06f3 -r e6ec5b2b717f

The initial values of the wallclock time in the shared info page are set for PVHVM guests when the hypercall page is initialized, since the hypercall page is not reinitialized on resume, the hypervisor wallclock time is not properly set on resume. Fix it by forcing an update of the wallclock values when the shared info page is mapped. Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>

From: Yang Zhang <yang.z.zhang@Intel.com> The follwoing patches are adding the Posted Interrupt supporting to Xen: Posted Interrupt allows vAPIC interrupts to inject into guest directly without any vmexit. - When delivering a interrupt to guest, if target vcpu is running, update Posted-interrupt requests bitmap and send a notification event to the vcpu. Then the vcpu will handle this

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),

Changes from v2 to v3: - Use pfn_to_paddr() to get the address from frame number instead of doing shift directly. - Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields. - Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled. - Use clear_page() to set all 0 to the page instead of memset(). - Use domheap to allocate the

Why is there an argument returned in the function below (of hvm.h), knowing that there is void? static inline void hvm_init_ap_context(struct vcpu_guest_context *ctxt, int vcpuid, int trampoline_vector) { return hvm_funcs.init_ap_context(ctxt, vcpuid, trampoline_vector); } _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hello, I am wondering if anyone could help me out with the following questions: 1. How to uninstall Samba? 2. How to install/upgrade/uninstall Samba from Mandrake 9.0 to the latest Samba version via source code (I noticed that MDK9 installed Samba to different places. And the document:"Using Samba" mentioned the file "inetd.conf" but I couldn't find it in MDK9.)

Hi I am completely new to LLVM, and I am trying to explore the alias analysis part of it. It seems to me that -basicaa is the most simple alias analysis pass in LLVM. So I would like to try and make it work (to see some alias analysis results of some sample bit code). What I have done is that I ---make lib/Analysis/BasicAliasAnalysis.cpp into a .so file ---write a sample c program, hello.c,

The previous order of relinquish resource is: relinquish_domain_resources() -> vcpu_destroy() -> nvmx_vcpu_destroy(). However some L1 resources like nv_vvmcx and io_bitmaps are free in nvmx_vcpu_destroy(), therefore the relinquish_domain_resources() will not reduce the refcnt of the domain to 0, therefore the latter vcpu release functions will not be called. To fix this issue, we need to

Hi, I encountered a problem about volatile quantifier when using llvm-gcc, here is the example: #define N 10 int sum(volatile int a[N]) { int sum = 0; unsigned i = 0; for (i = 0; i < N; ++i) sum += a[i]; return sum; } If I compile it as C code, then llvm-gcc will dump: define i32 @sum(i32* nocapture %a) nounwind { bb1.thread: %0 = volatile load i32* %a, align 4

Hi there, I am trying to understand how AliasAnalysis works out in LLVM. I used the following simple test-case (test4.c): -- void test() { int *jj, *kk; int aa = 100; jj = &aa; *jj = 300; } int main() { test(); return 0; } -- Then I did "llvm-gcc -emit-llvm -c -o test4.bc test4.c" to get bc. I tried the following 2 ways to get what I expect to get as

Hi, Just a quick question. I wonder if the package of "car" has been removed from the most current version of R. Or what can I do to renew it since I have to do the analysis with that? Thanks, yen

Hi, Here is C function: uint64_t mul(uint32_t x, uint32_t y) { return x * y; } current llvm-gcc-4.0 with -O3 will compile it to: define i64 @mul(i32 %x, i32 %y) nounwind { entry: %tmp3 = mul i32 %y, %x ; <i32> [#uses=1] %tmp34 = zext i32 %tmp3 to i64 ; <i64> [#uses=1] ret i64 %tmp34 } This seems incorrect. I think it should extend %x, %y to i64 first and

The paravirtualized guests are offered wallclock time referenced to UTC only, while fully virtualized guests are given the option via the config file (localtime parameter) of starting with UTC time or local time. What would it take to optionally provide localtime to the paravirtualized guests as well? For a guest that launches assuming localtime as its time basis, then later deriving UTC from it
