ring_id
|
|
|
|
The buffer pointer ring ID.
|
|
|
|
0 refers to the IDLE ring
|
|
|
|
1 - N refers to other rings
|
|
|
|
|

|
|
Helps with debugging when dumping ring contents.

looping_count
|
|
|
|
A count value that indicates the number of times the
|
|
producer of entries into the Ring has looped around the
|
|
ring.
|
|
|
|
At initialization time, this value is set to 0. On the
|
|
first loop, this value is set to 1. After the max value is
|
|
reached allowed by the number of bits for this field, the
|
|
count value continues with 0 again.
|
|
|
|
In case SW is the consumer of the ring entries, it can
|
|
use this field to figure out up to where the producer of
|
|
entries has created new entries. This eliminates the need to
|
|
check where the head pointer' of the ring is located once
|
|
the SW starts processing an interrupt indicating that new
|
|
entries have been put into this ring...
|
|
|
|
Also note that SW if it wants only needs to look at the
|
|
LSB bit of this count value.
