◆ AR5K_MAX_RATES

#define AR5K_MAX_RATES 32

Seems the ar5xxx harware supports up to 32 rates, indexed by 1-32.

The rate code is used to get the RX rate or set the TX rate on the hardware descriptors. It is also used for internal modulation control and settings.

This is the hardware rate map we are aware of:

rate_code 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 rate_kbps 3000 1000 ? ? ? 2000 500 48000

rate_code 0x09 0x0A 0x0B 0x0C 0x0D 0x0E 0x0F 0x10 rate_kbps 24000 12000 6000 54000 36000 18000 9000 ?

rate_code 17 18 19 20 21 22 23 24 rate_kbps ? ? ? ? ? ? ? 11000

rate_code 25 26 27 28 29 30 31 32 rate_kbps 5500 2000 1000 11000S 5500S 2000S ? ?

"S" indicates CCK rates with short preamble.

AR5211 has different rate codes for CCK (802.11B) rates. It only uses the lowest 4 bits, so they are the same as below with a 0xF mask. (0xB, 0xA, 0x9 and 0x8 for 1M, 2M, 5.5M and 11M). We handle this in ath5k_setup_bands().

For more details, refer to: http://www.freepatentsonline.com/20030225739.html @AR5K_INT_RXORN: Indicates we got RX overrun (eg. no more descriptors). Note that Rx overrun is not always fatal, on some chips we can continue operation without reseting the card, that's why int_fatal is not common for all chips. @AR5K_INT_TX: mask to identify received frame interrupts, of type AR5K_ISR_TXOK or AR5K_ISR_TXERR @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor (?) @AR5K_INT_TXURN: received when we should increase the TX trigger threshold We currently do increments on interrupt by (AR5K_TUNE_MAX_TX_FIFO_THRES - current_trigger_level) / 2 @AR5K_INT_MIB: Indicates the Management Information Base counters should be checked. We should do this with ath5k_hw_update_mib_counters() but it seems we should also then do some noise immunity work. @AR5K_INT_RXPHY: RX PHY Error @AR5K_INT_RXKCM: RX Key cache miss @AR5K_INT_SWBA: SoftWare Beacon Alert - indicates its time to send a beacon that must be handled in software. The alternative is if you have VEOL support, in that case you let the hardware deal with things. @AR5K_INT_BMISS: If in STA mode this indicates we have stopped seeing beacons from the AP have associated with, we should probably try to reassociate. When in IBSS mode this might mean we have not received any beacons from any local stations. Note that every station in an IBSS schedules to send beacons at the Target Beacon Transmission Time (TBTT) with a random backoff. @AR5K_INT_BNR: Beacon Not Ready interrupt - ?? @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill, disabled for now until properly handled @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by DMA errors. These types of errors we can enable seem to be of type AR5K_SIMR2_MCABT, AR5K_SIMR2_SSERR and AR5K_SIMR2_DPERR. @AR5K_INT_GLOBAL: Used to clear and set the IER @AR5K_INT_NOCARD: signals the card has been removed @AR5K_INT_COMMON: common interrupts shared amogst MACs with the same bit value

These are mapped to take advantage of some common bits between the MACs, to be able to set intr properties easier. Some of them are not used yet inside hw.c. Most map to the respective hw interrupt value as they are common amogst different MACs.

ath5k_hw_attach - Check if hw is supported and init the needed structs

@sc: The &struct ath5k_softc we got from the driver's attach function @mac_version: The mac version id (check out ath5k.h) based on pci id @hw: Returned newly allocated hardware structure, on success

Check if the device is supported, perform a POST and initialize the needed structs. Returns -ENOMEM if we don't have memory for the needed structs, -ENODEV if the device is not supported or prints an error msg if something else went wrong.

int ath5k_hw_update_tx_triglevel	(	struct ath5k_hw *	ah,

ath5k_hw_update_tx_triglevel - Update tx trigger level

@ah: The &struct ath5k_hw @increase: Flag to force increase of trigger level

This function increases/decreases the tx trigger level for the tx fifo buffer (aka FIFO threshold) that is used to indicate when PCU flushes the buffer and transmits it's data. Lowering this results sending small frames more quickly but can lead to tx underruns, raising it a lot can result other problems (i think bmiss is related). Right now we start with the lowest possible (64Bytes) and if we get tx underrun we increase it using the increase flag. Returns -EIO if we have have reached maximum/minimum.

XXX: Link this with tx DMA size ? XXX: Use it to save interrupts ? TODO: Needs testing, i think it's related to bmiss...

ath5k_hw_set_bssid_mask - filter out bssids we listen

@ah: the &struct ath5k_hw @mask: the bssid_mask, a u8 array of size ETH_ALEN

BSSID masking is a method used by AR5212 and newer hardware to inform PCU which bits of the interface's MAC address should be looked at when trying to decide which packets to ACK. In station mode and AP mode with a single BSS every bit matters since we lock to only one BSS. In AP mode with multiple BSSes (virtual interfaces) not every bit matters because hw must accept frames for all BSSes and so we tweak some bits of our mac address in order to have multiple BSSes.

NOTE: This is a simple filter and does not filter out all relevant frames. Some frames that are not for us might get ACKed from us by PCU because they just match the mask.

When handling multiple BSSes you can get the BSSID mask by computing the set of ~ ( MAC XOR BSSID ) for all bssids we handle.

When you do this you are essentially computing the common bits of all your BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with the MAC address to obtain the relevant bits and compare the result with (frame's BSSID & mask) to see if they match.

ath5k_hw_noise_floor_calibration - perform PHY noise floor calibration

@ah: struct ath5k_hw pointer we are operating on @freq: the channel frequency, just used for error logging

This function performs a noise floor calibration of the PHY and waits for it to complete. Then the noise floor value is compared to some maximum noise floor we consider valid.

Note that this is different from what the madwifi HAL does: it reads the noise floor and afterwards initiates the calibration. Since the noise floor calibration can take some time to finish, depending on the current channel use, that avoids the occasional timeout warnings we are seeing now.

See the following link for an Atheros patent on noise floor calibration: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL \ &p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7245893.PN.&OS=PN/7

XXX: Since during noise floor calibration antennas are detached according to the patent, we should stop tx queues here.
