When the other end notifies us that there are commands to be read
(pvcalls_back_event), wake up the backend thread to parse the command.
The command ring works like most other Xen rings, so use the usual
ring macros to read and write to it. The functions implementing the
commands are empty stubs f
Implement the accept command by calling inet_accept. To avoid blocking
in the kernel, call inet_accept(O_NONBLOCK) from a workqueue, which get
scheduled on sk_data_ready (for a passive socket, it means that there
are connections to accept).
Use the reqcopy field to store the request. Accept the ne
Introduce a per-frontend data structure named pvcalls_fedata. It
contains pointers to the command ring, its event channel, a list of
active sockets and a tree of passive sockets (passing sockets need to be

sockets only on relea

It works for me. FYI I sent a separate invite to discuss EL0 apps and
stubdoms on ARM (alpine.DEB.2.10.1706151117090.12156@sstabellini-T
Hi all,
Would you be up for joining a conf call to discuss EL0 apps and stubdoms
on ARM in preparation for Xen Developer Summit?
If so, would Wednesday the 28th of June at 9AM PST work for you?
I realize we also have the ARM community call next well, but this is a
large topic which deserves an e
