IF guest CR0.wp is 0 and the destination address is ReadOnly, we have to emulate it.

With the only bit in CR0 permitted to be changed by PV guests being TS, optimize the handling towards that: Keep a cached value in a per-CPU variable, and issue HYPERVISOR_fpu_taskswitch hypercalls for updates in all but the unusual case should something in the system still try to modify another bit (the attempt of which would then be logged by the hypervisor). This removes the need to have the

If you use -MMD -MF then the correct .o filename is written to the .*.d file as the compiler driver arranges everything. This was done in 19010:275abe1c5d24 for the hypervisor. In this patch we do the same elsewhere in the xen-unstable tree, particularly tools/. Specifically: * Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS. * Remove -Wp,-MD... from every other Makefile *

Hello! I''m working on a guest OS port which uses NetBSD drivers, and I''m currently working on the netfront support. I''m basing the driver on the FreeBSD 7.0 driver, and I''ve run into a problem in network_alloc_rx_buffers. Parts of the code with line numbers is given below, and I''ll try to explain where the problem occurs. The basic problem is that

Changes from v1 to v2: - Use a macro to replace the hardcode in patch 1/3. This patchset fixes issues about IA32_VMX_MISC MSR emulation, VMCS guest area synchronization about PAGE_FAULT_ERROR_CODE_MASK/PAGE_FAULT_ERROR_CODE_MATCH, and CR0/CR4 emulation. Please help to review and pull. Thanks, Dongxiao Dongxiao Xu (3): nested vmx: emulate IA32_VMX_MISC MSR nested vmx: synchronize page

Hi all don''t get such envionment to try now. so ask for help here. imagine that two os installed. Xen3.1 + Linux is installed in /dev/hda and windows xp is installed in /dev/hdb I don''t want to reboot to use windows. Is it possiable to boot the hdb windows in xen? i saw there are some threads about P2V in this mail list. will the P2V tools help? thanks

Hello, We''re curious about page fault handling in Xen-devel. In particular, during kernel boot-up, the kernel tests if the CPU "honours the WP bit". This causes a page fault with error code 3 (expected behavior). Does Xen still make a copy of the execution stack frame on the guest OS stack, as specified in the original "Xen and the Art of Virtualization" paper?

G'day all, I'm always running the latest wine built locally, daily from CVS. I'm using Xfree 4.0.2 with a microtouch touchscreen, and I'm chasing a mouse event bug. I write my software in Borland Delphi 4. For testing, I have written a program that simply intercepts the application message queue, and filters WM_MOUSEMOVE, WM_LMOUSEDOWN and WM_LMOUSEUP events, and prints them to a

Hi, Rsync 3.0.5 on both sides. receiver is Open Solaris and sender is Linux. I got a nested directory - relatively depth but still it should work. It fails instead. sending daemon args: --server --sender -vvlWHogDtpre.is --ignore-errors --numeric-ids --inplace .

Sadly the latest optimization broke completely everything. The asm code isn't gas compliant. the libFLAC linker script has a typo, disabling the asm optimization and/or altivec won't let a correct build anyway. Instant fixes for the asm stuff: sed -i -e"s:;:\#:" on the lpc_asm.s to load address instead of addis+ori you could use lis and la and PLEASE use the @l(register)

We are reading big tables, such as, Chemicals <- read.table('ftp://ftp.bls.gov/pub/time.series/wp/wp.data.7.Chemicals',header = TRUE, sep = '\t', as.is =T) I was wondering if it is possible to set a filter during loading so that we just load what we want not the whole table each time.

Evan, et al., I've come across a small issue when using the if conversion pass in PPC to generate conditional returns. Here's a small example: ** Before if conversion ** BB#0: derived from LLVM BB %entry %R3<def> = LI 0 %CR0<def> = CMPLWI %R3, 0 BCC 68, %CR0, <BB#3> Successors according to CFG: BB#3(16) BB#1(16) BB#1: derived from LLVM BB
