2 | * General Purpose functions for the global management of the | ||
3 | * Communication Processor Module. | ||
4 | * Copyright (c) 1997 Dan error_act (dmalek@jlc.net) | ||
5 | * | ||
6 | * In addition to the individual control of the communication | ||
7 | * channels, there are a few functions that globally affect the | ||
8 | * communication processor. | ||
9 | * | ||
10 | * Buffer descriptors must be allocated from the dual ported memory | ||
11 | * space. The allocator for that is here. When the communication | ||
12 | * process is reset, we reclaim the memory available. There is | ||
13 | * currently no deallocator for this memory. | ||
14 | * The amount of space available is platform dependent. On the | ||
15 | * MBX, the EPPC software loads additional microcode into the | ||
16 | * communication processor, and uses some of the DP ram for this | ||
17 | * purpose. Current, the first 512 bytes and the last 256 bytes of | ||
18 | * memory are used. Right now I am conservative and only use the | ||
19 | * memory that can never be used for microcode. If there are | ||
20 | * applications that require more DP ram, we can expand the boundaries | ||
21 | * but then we have to be careful of any downloaded microcode. | ||
