staging/mei: Interrupt handling.
ISR and interrupt thread for handling incoming data.
e.g. read bus message, read client message, handle reset requests.
quick handler:
As MEI may share interrupt with GFX and/or USB
the HW register need to be checked and acknowledged.
thread handler:
Check if HW has data for read.
Write data to HW if possible.
May init reset flow on error
there can be two types of messages:
1) bus messages:
Management messages between MEI Driver and ME e.g.
Connect request/response,
Disconnect request/response
Enum clients request/response
Flow control request/response
those message are indicated by
ME Address/ID == 0 && Host Address/ID == 0
2) feature/client messages:
message that are sends between ME Feature/Client and
an application, the struct of the message is defined
by the ME Feature Protocol (e.g. APF Protocol, AMTHI Protocol)
those message are indicated by
ME Address/ID != 0 && Host Address/ID != 0
MEI Initialization state machine is also managed by this patch.
After MEI Reset is preform:
Send Start request
wait for answer
Send Enumerate Clients request
wait for answer
Send Get Client property for each client request
wait for answers
Init Done.
