Hi! The MCG_CAP MSR never returns a negative count of available error-reporting banks. Thus make nr_mce_banks unsigned. While here, do some other minor cleanups.

Hi Keir, Attached patch gets rid of the global attr variable and adds support for NetBSD.

Since the emulator now supports a few 256-bit memory operations, this array needs to follow (and the comments should, too). To limit growth, re-order the mmio_large_write_* fields so that the two mmio_large_*_bytes fields end up adjacent to each other.

Hi! Attached patch removes gfn_to_mfn_current(). It is redundant and effectively unused. All remaining users now use proper replacement function. => No functional change.

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

This patch series tidies up a few bits ofthe nested p2m code. The main thing it does is reorganize the locking so that most of the changes to nested p2m tables happen only under the p2m lock, and the nestedp2m lock is only needed to reassign p2m tables to new cr3 values. Changes since v1: - a few minor fixes - more sensible flushing policy in p2m_get_nestedp2m() - smoke-tested this time!

Hi! I cleaned up xen/include/asm-x86/guest_access.h. I also fixed a bug in __copy_field_from_guest(), which seems to me to be a kind of cut-copy-paste bug. copy_{to,from}_user() and copy_{to,from}_user_hvm() expect a non-const argument as the first argument. So I remove the consts from the initializer. I replace typeof with __typeof__, which is always available in gcc - it is not, when the

Hi, Attached patch implements the VMCB cleanbits SVM feature. Upcoming AMD CPUs introduce them and they are basically hints for the CPU which vmcb values can be re-used from the previous VMRUN instruction. Each bit represents a certain set of fields in the VMCB. Setting a bit tells the cpu it can re-use the cached value from the previous VMRUN. Clearing a bit tells the cpu to reload the values

Hi! This is the third and last patch. This patch makes the xen kernel buildable on OpenBSD by adding support for ProPolice. ProPolice has been added to standard GCC in version 4.1.x under the name Stack Smashing Protection (SSP).

Hi all! Did the nested xen stuff make it into the xen-unstable (4.1-rc1?) tree as suggested back in January by Tim Deegan?

For compiling the xen kernel we use -nostdinc which means we don''t want to rely on any external headers. That also counts vor stdarg.h. Use the external header when we compile the tools.

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! The xen-cast.diff adds the -Wcast-qual flag. The xen-cast-xen.diff makes the hypervisor itself buildable with the new flag - at least on x86_32 and x86_64. The xen-cast-tools.diff makes the tools build with the new flag. Generally, the places with the __UNCONST() hack should be considered to be reworked. These places may hide bugs. Christoph

Hi! If there is a string table for section headers, it also gets loaded. Therefore take it into account in size calculation for kernel symtab.

Keir, I noticed that a Shadow patch went into the 3.1.1 staging tree today. Does this mean that we should expect a 4th release candidate before the 3.1.1 release tag is official? If so - how much testing time are you going to give that release candidate before deciding whether a release tag, or another RC round is appropriate?

Hi Keir, For HVM guests, all cpuid Fn''s going through domain_cpuid() iterate over the loop and then return 0 for all four registers. Guests OS''s and cpuid tools in HVM which query for cpuid Fn 0000.0000 %eax and 8000.0000 %eax, see the value 0 and think, Xen emulates oldish 386/486 CPUs. This leads to strange boot failures, "your CPU does not support long mode" or
