7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * The short description of each module is as below:
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * Module 1: GLD callback functions, which are intercepting the calls from
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * GLD to LLD.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * Module 2: Net80211 callback functions registered by LLD, which
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * calls into LLD for H/W related functions needed by net80211.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * Module 3: LLD Internal functions, which are responsible for allocing
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * descriptor/buffer, handling interrupt and other H/W
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * operations.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * All functions are running in 3 types of thread:
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * 1. GLD callbacks threads, such as ioctl, intr, etc.
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * 2. Clock interruptt thread which is responsible for scan, rate control and
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * calibration.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * 3. Software Interrupt thread originated in LLD.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * The lock strategy is as below:
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * There have 4 queues for tx, each queue has one asc_txqlock[i] to
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * prevent conflicts access to queue resource from different thread.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * All the transmit buffers are contained in asc_txbuf which are
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * protected by asc_txbuflock.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * Each receive buffers are contained in asc_rxbuf which are protected
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * by asc_rxbuflock.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * In ath struct, asc_genlock is a general lock, protecting most other
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * operational data in ath_softc struct and HAL accesses.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * It is acquired by the interupt handler and most "mode-ctrl" routines.
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * Any of the locks can be acquired singly, but where multiple
7a1306a70fee0e017a445bde1dcfd1997f691cf4xc * locks are acquired, they *must* be in the order:
0ba2cbe97e0678a691742f98d2532caed0a2c4aaxc * asc_genlock >> asc_txqlock[i] >> asc_txbuflock >> asc_rxbuflock
