MAX_NR_IO_RANGES is used by ioreq server as the maximum
number of discrete ranges to be tracked. This patch changes
its value to 8k, so that more ranges can be tracked on next
generation of Intel platforms in XenGT. Future patches can
extend the limit to be toolstack tunable, and MAX_NR_IO_RANGES
This patch introduces a new data structure, struct rb_rangeset,
to represent a group of continuous ranges, e.g. the start and end
addresses for PIO/MMIO regions. By now, this structure is supposed
to assist ioreq server to forward the I/O request to backend device
models more efficiently.
XenGT leverages ioreq server to track and forward the accesses to
GPU I/O resources, e.g. the PPGTT(per-process graphic translation
tables). Currently, ioreq server uses rangeset to track the BDF/
PIO/MMIO ranges to be emulated. To select an ioreq server, the
rangeset is searched to see if the I/O
'pfn' and 'start_pfn' are ambiguous, both these functions expect GFNs as input.
On x86 the interface of p2m_set_mem_access() in p2m.c doesn't match the
declaration in p2m-common.h as 'pfn' is being used instead of 'start_pfn'.

Check whether QEMU supports the xsrestrict option, by parsing its --help
output. Store the result on xenstore for future reference on a per QEMU
binary basis, so that device_model_override still works fine with it.
Replace / with _ in the QEMU binary path before writing it to xenstore,
so that it
Change the qdisk-backend-pid path on xenstore from
libxl/$DOMID/qdisk-backend-pid to /local/domain/$DOMID/image/pvqemu-pid to be

Hi all,
this patch series changes libxl to start QEMU as device model with the
new xsrestrict option (http://marc.info/?l=xen-develm=143341692707358).
It also starts a second QEMU to provide PV backends in userspace (qdisk)
to HVM guests.

whether a register belongs to PMU.
This and some of subsequent PMU emulation code is somewhat similar to
Xen's PMU implementation.

Starts a second QEMU to provide PV backends in userspace to HVM guests.
Use both dcs-dmss.pvqemu and dcs-dmss.dm to keep track of the starting
QEMUs. Introduce two new fields to struct libxl__dm_spawn_state: dcs to
store the pointer to libxl__domain_create_state, and rc to store the
return code.

Add PMU emulation code that runs when we are processing a PMU interrupt.
This code will allow us not to trap to hypervisor on each MSR/LVTPC access

I haven't posted Linux part of PV(H) VPMU support in a while but now
that (hopefully) the hypervisor part is getting close to be done I
think it's time to post it again.
There are very few differences compared to the last version, mostly due
to updates in shared structures layouts. Patches 1 and
