Subject: [PATCH] qxl: Add set_client_capabilities() interface to QXLInterface
|
|
|
|
This new interface lets spice server inform the guest whether
|
|
|
|
(a) a client is connected
|
|
(b) what capabilities the client has
|
|
|
|
There is a fixed number (464) of bits reserved for capabilities, and
|
|
when the capabilities bits change, the QXL_INTERRUPT_CLIENT interrupt
|
|
is generated.
