similar to: [PATCH] small mca cleanup

Hello! The current MCA/MCE support in Xen is that it dumps the error and panics. In the following concept I propose here, there are two places where Xen has to react on. I) Xen receives a MCE from the CPU and II) Xen receives Dom0 instructions via Hypercall The term "self-healing" below is used in the sense of using the most propriate technique(s) to handle an error such as MPR

Hi! Attached patch makes git-ioemu compile on NetBSD. Signed-off-by: Christoph Egger <Christoph.Egger@amd.com> P.S.: I''m about sending the pieces to qemu-devel. The changes in vl.c already went upstream in qemu''s svn c/s 5646. -- AMD Saxony, Dresden, Germany Operating System Research Center Legal Information: AMD Saxony Limited Liability Company & Co.

Hi! On BSD, mmap()ing files works on on-disk files but not on pseudo filesystems like kernfs or procfs. Therefore, attached patch mmap()s anonymous memory. Linux equivalents are sysfs and procfs to above BSD''s pseudo-filesystems. On Linux, mmap is implemented for sysfs but it is questionable to me how write operations work since (most) files in sysfs have static content. So this patch

Hi! Changeset 17913 breaks build on *BSD: block-qcow.c:36:20: error: gcrypt.h: No such file or directory cc1: warnings being treated as errors block-qcow.c: In function ''gen_cksum'': block-qcow.c:160: warning: implicit declaration of function ''gcry_md_hash_buffer'' block-qcow.c:160: error: ''GCRY_MD_MD5'' undeclared (first use in this function)

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. Also there is no need to call elf_set_verbose() a second time after elf_init() (First call happens within elf_init()).

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

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, This is updated xen vMCE design foils, according to comments from community recently. This foils focus on vMCE part of Xen MCA, so as Keir said, it''s some dense. Later Will will present a document to elaborate more, including Intel MCA and surrounding features and Xen implementation. Thanks, Jinsong

Hi! In struct ioreq are the "addr", "size", "count" and "data" 64bit fields. So handle 64bit operations in stdvga instead of throwing away the upper 32bits (see attached patch).
