System—Packet Holding Message Blocks...

The DACS system manages the i960 processor utilization by allocating message blocks for packet manage- ment. This Message Blocks window (see figure 37) indicates buffer usage of DACS message blocks based upon message block sizes.

Figure 37. Packet Holding Message Blocks window

Buffer Size (boxbuffersize)

The size in bytes of the buffer.

No. of Buffers (boxbuffercount)

The total number of buffers this size.

No. Free (boxbuffersfree)

The number of buffers this size which are currently free for use

No. of Tasks Waited (boxCountBufferTaskWait)

The total number of times that the proper size message block was not available to hold a packet, and the CPU task went to sleep while waiting for it.

No. of Times Unavailable(boxCountBufferUnavailable)

The total number of times that the proper size message block was not available to hold a packet, and the CPU task dumped the packet. The difference between Total Time Waited and Total Times Unavailable is whether the CPU task goes to sleep or simply dumps the packet to continue on.
