| Description | Entries in this table define entities (buffer pools
in this case) which are contained in an entity
(memory pool) defined by an entry from
cempMemPoolTable.
-- Basic Pool Architecture --
1)Pools are classified as being either Static or
Dynamic. Static pools make no attempt to increase
the number of buffers contained within them if the
number of free buffers (cempMemBufferFree) are less
than the number of minimum buffers (cempMemBufferMin).
With Dynamic pools, the pool attempts to meet the
demands of its users.
2)Buffers in a pool are classified as being either
Permanent or Temporary. Permanent buffers, as their
name suggests, are always in the pool and are never
destroyed unless the number of permanent buffers
(cempMemBufferPermanent) is changed. Temporary
buffers are transient buffers that are created in
dynamic pools whenever the free count
(cempMemBufferFree) of buffers in the pool drops
below the minimum (cempMemBufferMin).
3)Buffers pools are classified as either Public or
Private. Public pools are available for all users
to allocate buffers from. Private pools are
primarily used by interface drivers. |
