This patch replaces the Xen xmalloc engine with tlsf, an allocation engine that is both more space efficient and time-bounded, especially for allocation sizes between PAGE_SIZE/2 and PAGE_SIZE. The file xmalloc.c is deprecated but not yet deleted. A simple switch of a comment line in common/Makefile will change back to the legacy xmalloc/xfree if needed for testing. Code adapted from Nitin

Folks, A new release candidate for 3.2.0 has just been checked into the xen-unstable tree. It''s available from staging and will be in the main tree when it has passed internal regression tests. Meanwhile, in preparation for 3.1.3, please let me know if there are any further patches from xen-unstable that should be backported into the 3.1 branch. You can pull the xen-3.1-testing.hg

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

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! 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()).

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

Various versions of Linux under various circumstances select TSC as the primary clocksource for the kernel. This is especially true for uniprocessor kernels, but also in some cases for multiprocessor kernels. In most cases, this is because a processor bit (tsc_invariant? constant_tsc?) is passed through directly from the hardware via Xen and tested by the hvm guest and the result implies that

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

Hi Folks, I see that currently Xen doesn''t export the machine check exceptions to dom0. Is there any plans to export this information to Dom0 (so that it can be read by utilities like mcelog) or is there already some ongoing work on this?

Hello, I have a question about the way Xentrace takes a trace. In previous versions of Xen, I took a trace by setting the size of buffers, activating them and writing the information into a file (optional). setsize 20 tbctl 1 xentrace /tmp/xentrace.dat Now I''m using xen-unstable and I see that setsize is already integrated in xentrace command. My question is: does start/stop buffer is

A while ago (I think at the Xummit), I recall someone saying that the structure of the files in xenlinux may change soon so that the xen-specific files would move to a subdirectory or arch/<arch> (e.g. linux/arch/i386/xen instead of linux/arch/xen/i386). Is this still planned? If so, what is the timing? If it''s in progress, I''d like to get in the loop... Thanks, Dan
