Additionally, none of the three associated memory allocations got checked for being successful.

Hi guys, I updated the latest xen hg repository, and found it failed to compile, because of an missing head file xenbus_dev.h. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, This patch allows userspace tools on a domU to setup a watch on the xenstore. It does this by intercepting XS_WATCH requests written to /proc/xen/xenbus and then re-submitting the request to the in-kernel xenstore interface, in linux-2.6-xen-sparse/drivers/xen/xenbus/xenbus_xs.c. When a callback occurs, an in-kernel function is invoked, which then reconstructs a response in the format

Hi, Anybody (Christian?) could please tell me if we can get the support for registering watch with /proc/xen/xenbus? (..OK, I know that we will change it this /proc stuff to a device soon) So far we can only do read/write/rm. I really miss the xen watch feature.

Dear xen-devel, There''s a race condition in xenfs (xenstore driver) that causes userspace utility xenstore-watch to crash. Normally, the userspace process gets an "OK" from xenfs and then the watch fires immediately after. Occasionally, this happens the other way around: the watch fires before the driver sends "OK", which confuses the xenstore-watch client. It seems

It seems that xenstore watches do not work from domU userspace (they obviously do for drivers). In some preliminary debugging of this, there are two aspects of the failure: not sending the watch to xenstore and not handling watch events for userspace watches. The former can be easily fixed by adding the missing ''case XS_WATCH:'' to xenbus_dev_write() in xenbus_dev.c. The

Hi, i read the xenpm wiki page, but i cannot use the "p-states". xenpm shows: xenpm cpu id : 0 total C-states : 2 idle time(ms) : 1776034 C0 : transition [00000000000000000000] residency [00000000000000000000 ms] C1 : transition [00000000000000260278] residency
