dyoung | Define some bitfields that come from a reference driver.
|
| 1.22 |
| 08-Sep-2008 |
gmcgarry | branches: 1.22.2;
Replace most gcc-specific __attribute__ uses with BSD-style sys/cdef.h
preprocessor macros.
|
| 1.21 |
| 12-Jun-2008 |
dyoung | branches: 1.21.2;
Elaborate on a comment.
|

| 04-May-2008 |
martin | branches: 1.20.2; 1.20.4;
Move to standard TNF 2 clause license
|
| 1.19 |
| 16-Nov-2007 |
dyoung | branches: 1.19.14; 1.19.16; 1.19.18;
Cosmetic: rename some variables and constants. Move some constants
from atw.c to atwreg.h.
|
| 1.18 |
| 16-Nov-2007 |
dyoung | Replace some magic numbers with HFA3861A register names.
Do not alias the Rx descriptor word ar_ctl to ar_rssi with a #define.
Instead, call the member ar_ctlrssi.
Convert the ugly macro ATW_RXDESC_INIT() to an inline subroutine,
atw_rxdesc_init().
Do not load an empty IEEE80211_RADIOTAP_FLAGS field into the Tx
radiotap header.

| 1.17 |
| 09-Jan-2007 |
dyoung | branches: 1.17.18; 1.17.20; 1.17.24; 1.17.26;
Let the compiler know it should both pack the members of the rx/tx
descriptors without any padding between, and use 4-byte alignment.
|
| 1.16 |
| 26-Nov-2006 |
dyoung | Add 'volatile' to rx/tx descriptor fields.

Per discussion on tech-kern and tech-userlevel, move the bit-twiddling
macros, __BIT, __BITS, SHIFTIN, SHIFTOUT, and __arraycount() from
lib/libkern/libkern.h to sys/cdefs.h. Add a __-prefix to SHIFTIN
and SHIFTOUT, and add a manual page for the bit-twiddling macros,
bits(3).
Make the __BIT and __BITS macros "widthless," as best I can, by
changing their type to uintmax_t from uint32_t. XXX The manual
page lags this change by a bit.
Define __PRIxBIT and __PRIxBITS printf(3) format strings.
|
| 1.14 |
| 08-Mar-2006 |
dyoung | Change macro names to avoid collisions:
BIT -> __BIT
BITS -> __BITS
|
| 1.13 |
| 08-Mar-2006 |
dyoung | Move my bit-twiddling macros to libkern.h from my drivers, where
I had duplicated them. Improve the macros' names. Simplify their
implementation.
A brief description of each macro is below.
BIT(n): Return a bitmask with bit m set, where the least
significant bit is bit 0.
BITS(m, n): Return a bitmask with bits m through n, inclusive,
set. It does not matter whether m>n or m<=n.
The least significant bit is bit 0.
A "bitfield" is a span of consecutive bits defined by a
bitmask, where 1s select the bits in the bitfield. SHIFTIN,
SHIFTOUT, and SHIFTOUT_MASK help read and write bitfields
from device registers.
SHIFTIN(v, mask): Left-shift bits `v' into the bitfield
defined by `mask', and return them. No
side-effects.
SHIFTOUT(v, mask): Extract and return the bitfield selected
by `mask' from `v', right-shifting the
bits so that the rightmost selected bit
is at bit 0. No side-effects.
SHIFTOUT_MASK(mask): Right-shift the bits in `mask' so that
the rightmost non-zero bit is at bit
0. This is useful for finding the
greatest unsigned value that a bitfield
can hold. No side-effects. Note that
SHIFTOUT_MASK(m) = SHIFTOUT(m, m).
Examples:
/*
* Register definitions taken from the RFMD RF3000 manual.
*/
#define RF3000_GAINCTL 0x11 /* TX variable gain control */
#define RF3000_GAINCTL_TXVGC_MASK BITS(7, 2)
#define RF3000_GAINCTL_SCRAMBLER BIT(1)
/*
* Shift the transmit power into the transmit-power field of the
* gain-control register and write it to the baseband processor.
*/
atw_rf3000_write(sc, RF3000_GAINCTL,
SHIFTIN(txpower, RF3000_GAINCTL_TXVGC_MASK));
/*
* Register definitions taken from the ADMtek ADM8211 manual.
*
*/
#define ATW_RXSTAT_OWN BIT(31) /* 1: NIC may fill descriptor */
/* ... */
#define ATW_RXSTAT_DA1 BIT(17) /* DA bit 1, admin'd address */
#define ATW_RXSTAT_DA0 BIT(16) /* DA bit 0, group address */
#define ATW_RXSTAT_RXDR_MASK BITS(15,12) /* RX data rate */
#define ATW_RXSTAT_FL_MASK BITS(11,0) /* RX frame length, last
* descriptor only
*/
/* Extract the frame length from the Rx descriptor's
* status field.
*/
len = SHIFTOUT(rxstat, ATW_RXSTAT_FL_MASK);

dyoung | branches: 1.10.2; 1.10.6; 1.10.8;
Improve register definitions and slightly demystify some magic
numbers.
|

dyoung | Refine some register definitions.
|
| 1.8 |
| 31-May-2004 |
dyoung | Define several new registers for the ADM8211C/CR parts. Improve
old register descriptions.
|
| 1.7 |
| 17-Feb-2004 |
dyoung | Move the RF Microdevices RF3000 & Silicon Laboratories SI4126/SI4136
register sets into their own header files for re-use by future
drivers.
|
| 1.6 |
| 29-Jan-2004 |
dyoung | Fix whitespace in Si4126 register definitions.
|
| 1.5 |
| 29-Jan-2004 |
dyoung | Wrap the bit-twiddling macros so that they don't get redefined if
more than one header file defines them.
|
| 1.4 |
| 10-Jan-2004 |
dyoung | Use new docs provided by RFMD to give some meaning to
previously-undocumented registers and magic numbers on the RF3000
baseband.
|
| 1.3 |
| 07-Dec-2003 |
dyoung | Make the MASK_TO_SHIFT expression less "tall." Hopefully helps
work-around the gcc bug reported by Erik Osheim.
|
| 1.2 |
| 13-Oct-2003 |
dyoung | Why don't I make up my mind? No need to left-shift the country
codes when I right-shift the country-code register! Fixes a bug
reported by Dan Carosone: regulatory domain "ETSI" registered as
domain "Spain/Other", so he could only tune channels 10 and 11.
