Master window broadcast select mask
|
|
-----------------------------------
|
|
|
|
API currently provides no method to set or get Broadcast Select mask. Suggest
|
|
somthing like:
|
|
|
|
int vme_master_bmsk_set (struct vme_resource *res, int mask);
|
|
int vme_master_bmsk_get (struct vme_resource *res, int *mask);
|
|
|
|
|
|
Interrupt Generation
|
|
--------------------
|
|
|
|
Add optional timeout when waiting for an IACK.
|
|
|
|
|
|
CR/CSR Buffer
|
|
-------------
|
|
|
|
The VME API provides no functions to access the buffer mapped into the CR/CSR
|
|
space.
|
|
|
|
|
|
Mailboxes
|
|
---------
|
|
|
|
Whilst not part of the VME specification, they are provided by a number of
|
|
chips. They are currently not supported at all by the API.
|
|
|
|
|
|
