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

Folks, The second release candidate for Xen 3.4.0 is available at http://xenbits.xensource.com/xen-unstable.hg, tagged as ''3.4.0-rc2''. Please test! -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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

...d to 4.2 (and, if possible, 4.1). Thanks, Dan =================== The program xen-tmem-list-parse parses the output of xm/xl tmem-list into human-readable format. A missing NULL terminator sometimes causes garbage to be spewed where the two-letter pool type should be output.

Am I correct in reading the code that there is no "noht" (turn off hyperthreading) option in Xen (except in powerpc)? This was a surprise to me as I've seen it documented in various places and I recently suggested it as a diagnostic to a customer. =================================== If Xen could save time in a bottle / then clocks wouldn't virtually skew / It would save every

I''ve noticed with xen-unstable on my quad-core x dual-thread (that''s 8 processors to xen), the boot info spewed for all the C-state/P-state stuff quickly fills the xm dmesg buffer and I lose some of the early-in-boot lines. Do we really need to know "reg.{space_id,bit_width,bit_offset,access_size, address}" and all that other info? Even if so, is there a more compact

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

I see that "xl list" shows a domain waiting idly for console input as "r", whereas "xm list" shows the same domain as "b". I also see that the State field for "xl list" contains only three characters (e.g. "r--"), whereas "xm list" shows six (e.g. "-b----"). Is this expected/intended (e.g. "r" in xm list

I am adding code in Xen that printk''s a size_t and find that I can''t write code (short of ifdef''ing) that compiles on both 32-bit and 64-bit because size_t is typedef''d in Xen as an unsigned long.
