Kernel crash with acpi_processor, cpu_idle and intel_idle =y
Hi everyone,
When I set CONFIG_ACPI_PROCESSOR, CONFIG_CPU_IDLE and CONFIG_INTEL_IDLE
to y then I cannot boot Xen; there is a crash. If I turn
CONFIG_INTEL_IDLE off then the boot goes well and, after dom0 has
booted, xenpm works and gives some sane output, see below. I have
tested this with kernels 3.2 to 3.4.6.
Is it impossible to use INTEL_IDLE with Xen? If this is a known issue
then maybe

[PATCH v2] txt: 2/5 - ACPI Generic Address Structure for tboot shutdown
New versions of tboot support ACPI GAS (Generic Address Structure) for handling sleep states. This required a change to the tboot_shared_t data structure that is not backwards compatible. This patch requires that new version makes use of GAS when invoking tboot on shutdown.

[RFC PATCH] Exporting ACPI Pxx/Cxx states to other kernel subsystems (v1).
Hello,
The following patches are a solution to a problem we have encountered
when using the Xen hypervisor:
- Need Pxx/Cxx states to save on power consumption when using Xen (we
do want those datacenters to consume less power!),
- Also need to figure out the Turbo mode so that the scheduler can properly
boost a core for CPU bound guests.
In essence the Xen hypervisor requires that

[PATCH] xen-tmem-list-parse: fix ugly parse output
Hmmm... It appears I never posted the corrected version of this patch
so it never made it upstream. See:
http://lists.xen.org/archives/html/xen-devel/2011-11/msg00587.html
http://lists.xen.org/archives/html/xen-devel/2011-11/msg02145.html
It would be good if this very minor fix was also applied to 4.2
(and, if possible, 4.1).
Thanks,

xm list vs. xl list: more differences?
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

[PATCH 1/2] Implement APEI ERST feature to Xen
Implement APEI ERST feature to Xen
APEI are ACPI4.0 new features. It consists of ERST, BERT, HEST, and EINJ.
ERST is used to save fault error log to a platform persistent storage,
so that when reboot os can retrieve the error log and handle it.
This patch is used to implement ERST feature to Xen.
It consists of 3-level hierarchy: operation level, action level, and instruction level.

[LLVMdev] Proposal: ASan debugging API
Hi,
I would like to improve the debugging experience for ASan. The idea is to
have a couple of useful commands in LLDB (probably implemented as Python
scripts) that could help the user when they are debugging an ASan-enabled
binary. We already have some debugging API (asan_interface.h):
// Print the description of addr (useful when debugging in gdb).

Guest TSC and Xen (Intel and AMD feedback please)
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

FW: [PATCH] workqueue: cancel_delayed_work() should return %NULL if work item is idle
FYI, it is likely that ocfs2 will not work on 3.7-rcN until
the following one-line patch is merged, as the code in ramster
that provoked it is directly leveraged from ocfs2 o2net.

linux/arch/xen/i386 or linux/arch/i386/xen
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,

Effective July 5, I will be resigning from Oracle and "retiring"

Between now and July 5, I will be tying up loose ends related to

No noht?
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.

[PATCH] use tlsf for xmalloc engine
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.

[PATCH] symmetricalization of system info command xm info, top, dmesg and log
These xm info, top, dmesg and log requre no parameter.
But log''s error message differs from other 3 command''s error messages,
when parameter is given.
# xm log 1
Error: ''xm log'' requires 0 argument.
log Print the xend log
Other 3 commands ignore parameter.
I think it might be better symmetricalize.
