Subject: [PATCH 2/2] Add new client_present and client capabilities fields to QXLRom
|
|
|
|
The client_present field is a byte that is set of non-zero when a
|
|
client is connected and to zero when no client is connected.
|
|
|
|
The client_capabilities[58] array contains 464 bits that indicate the
|
|
capabilities of the client. Each bit corresponds to a
|
|
SPICE_DISPLAY_CAP_* capability. In particular, if the client has
|
|
capability C, then bit (C % 8) in byte (C / 8) is set. The capability
|
|
bits only have a defined meaning when a client is connected, ie., when
|
|
client_present is non-zero. The number 58 was chosen to fill out a
|
|
cache line in QXLRom.
|
|
|
|
A new QXL_INTERRUPT_CLIENT interrupt is defined, which will be raised
|
|
whenever a client connects or disconnects.
