The existing (legacy) format is dependant on the word size of the
toolstack. This prevents domains from migrating from hosts running
32-bit toolstacks to hosts ru

Hey, guys,
I know, I know, I'm s much late to the party! Sorry, I got trapped
into a thing that I really needed to finish... :-/
I've got no intention to resurrect this old thread, just wanted to
pointed out a few things.

Here's what I currently have:
introduce XENMEM_reserved_device_memory_map
This is a prerequisite for punching holes into HVM and PVH guests' P2M
to allow passing through devices that are associate

Hey George, Ian,
Ian: I copied your comment and stuffed it in, please Ack:
[PATCH v4.1 1/3] libxl/cpumap: Add xc_cpumap_[setcpu, clearcpu,
already Acked:
[PATCH v4.1 2/3] libxc/xentrace: Use xc_cpumap_t for
George: please review (it is unchanged since v4 posting):
[PATCH v4.1 3/3] xentrace:
From: George Dunlap
xentrace is the only caller at the moment. Split the cpu and event
mask setting out into seperate functions, but leave the current limit
of 32 bits for masks passed in from the command-line.
Based on a patch from Konrad Rzeszutek Wilk

We export the xc_cpumap_alloc but not the bit operations.
One could include 'xc_bitops.h' but that is naughty - so instead
we just export the proper functions to do it on the xc_cpumap_t
typedef.

v2: Use our own macro to make sure ARM is not affected nega
Instead of just using -c 0x we can
also use: -c -, -c ,, or a
combination of them, or 'all' for all cpus.
This new format can include just singular CPUs: -c ,
or ranges without an start or end (and xentrace will figure out
the values), such as: -c - (which will include cpu0, cpu1,
and cpu2) or -c
Apologies for breaking the threading. The mail server ate the thread and I
couldn't manage to get it back...

Hi,
This patch series ports the intel_pstate driver from the Linux kernel to
Xen. The intel_pstate driver is used to tune P states for SandyBridge+
processors. It can be disabled by adding "intel_pstate=disable" to the
booting parameter list.
The intel_pstate.c file under xen/arch/x86/acpi/cpuf
Stefano,
while I'm not really convinced of the change, commit 14655e9a18
("glib-compat: fix problems with not-quite glib 2.22") at least helps
with building on SLE11 SP3. My concern is that the fallback seems
worse than using the backported interface in glib, but I also can't
see a reasonable way
