...about event channel in Xenpaging to ask you. 1) In xenpaging it uses Inter-Domainain Commnication (IDC) between dom0 and domU to build bidirectional connection,but I found there is only an event channel notification from xen to dom0 when page faults happens.It seems that xenpaging_resume_page()->xc_evtchn_notify() doesn''t make any difference.So why don''t use vIRQ between dom0 and xen instead of IDC between dom0 and domU? 2)In your latest patch,[PATCH 9 of 9] xenpaging: watch the domains /xenpaging/num_pages xenstore value.I found some problems. a、In main(),you put the page_out process...

Hello, Sometimes the backend of PVFB knows that it doesn''t need permanent refresh, when the window is minimized for instance (no refresh at all), or the administration tools know that the window is thumnailed, and so a slow refresh rate is fine. Also, some users may want to tune the refresh rate according to the smoothness they would like, balanced with the CPU time that requires.

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and

Greetings all. Some small question regarding schedule poll operation hypercall. 1. struct sched_poll poll.timeout is measured in what unit of time? Secs, ms? ns? 2. After issuing the hypercall_sched_op(SCHEDOP_poll, &poll); if no timeout is used in poll struct how long will I yield the CPU? 3. If I issue the hypercall and the event never comes is it possible to to yield the CPU for ever?

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very

This patch series introduces the shared ring used by the front-end to pass request descriptors to tapdisk, as well as responses from tapdisk to the front-end. Requests from this ring end up in tapdisk''s standard request queue. When the tapback daemon detects that the front-end tries to connect to the back-end, it spawns a tapdisk and tells it to connect to the shared ring. The shared

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -
