* ath5k: fix interpolation with equal power levelsFabio Rossi2009-05-201-21/+28
| | | | | | | | | When the EEPROM contains weird values for the power levels we have to fix the interpolation process. Signed-off-by: Fabio Rossi <rossi.f@inwind.it> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath5k: fix exp off-by-one when computing OFDM delta slopeForrest Zhang2009-05-201-3/+3
| | | | | | | | | | | | | | | Commit e8f055f0c3b ("ath5k: Update reset code") subtly changed the code that computes floating point values for the PHY3_TIMING register such that the exponent is off by a decimal point, which can cause problems with OFDM channel operation. get_bitmask_order() actually returns the highest bit set plus one, whereas the previous code wanted the highest bit set. Instead, use ilog2 which is what this code is really calculating. Also check coef_scaled to handle the (invalid) case where we need log2(0).

| | | | | | | | | | | | AR5K_PHY_PLL_40MHZ_5413 should not be ORed with AR5K_PHY_MODE_RAD_RF5112 for 5 GHz channels.

* ath5k: update channel in sw state after stopping RX and TXBob Copeland2009-05-111-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a non-theoretical race condition when transmitting and receiving frames during a scan. If the channel or operating band changes while processing status descriptors in the tasklets, ath5k will incorrectly use the new channel and band when reporting the rates, even if the frame was actually sent on a previous channel. Typically this will manifest as a beacon found on an incorrect frequency and/or a warning in the driver while scanning: [ 4773.891944] cfg80211: Found new beacon on frequency: 5805 MHz (Ch 161) on phy0 [ 4785.461125] ------------[ cut here ]------------ [ 4785.461135] WARNING: at drivers/net/wireless/ath/ath5k/base.c:1141 ath5k_tasklet_rx+0x2ff/0x577 [ath5k]() [ 4785.461143] Hardware name: MacBook1,1 [ 4785.461148] invalid hw_rix: 1b [ 4785.461152] Modules linked in: fuse i915 drm af_packet acpi_cpufreq binfmt_misc dm_mirror dm_region_hash dm_log dm_multipath dm_mod arc4 ecb snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_seq_dummy snd_seq_oss snd_seq_midi_event ath5k snd_seq hid_apple usbhid snd_seq_device mac80211 appletouch snd_pcm_oss sky2 ohci1394 snd_mixer_oss ath ieee1394 snd_pcm bitrev snd_timer cfg80211 crc32 snd snd_page_alloc button processor ac ehci_hcd joydev uhci_hcd sg battery thermal sr_mod cdrom applesmc evdev input_polldev unix [last unloaded: microcode] [ 4785.461296] Pid: 0, comm: swapper Tainted: G W 2.6.30-rc3-wl #112 [ 4785.461302] Call Trace: [ 4785.461316] [<c012590f>] warn_slowpath+0x76/0xa5 [ 4785.461331] [<c0219839>] ? debug_dma_unmap_page+0x5a/0x62 [ 4785.461357] [<f9982f88>] ath5k_tasklet_rx+0x2ff/0x577 [ath5k] [ 4785.461371] [<c01446f7>] ? trace_hardirqs_off+0xb/0xd [ 4785.461381] [<c0129928>] ? __tasklet_schedule+0x6e/0x7c [ 4785.461392] [<c0129b02>] tasklet_action+0x92/0xe5 [ 4785.461402] [<c0129f91>] __do_softirq+0xb1/0x182 [ 4785.461411] [<c012a092>] do_softirq+0x30/0x48 [ 4785.461428] [<c012a20a>] irq_exit+0x3d/0x74 [ 4785.461435] [<c035a0de>] do_IRQ+0x76/0x8c [ 4785.461440] [<c010312e>] common_interrupt+0x2e/0x34 [ 4785.461445] [<c014007b>] ? timer_list_show+0x1ab/0x939 [ 4785.461457] [<f85fd25c>] ? acpi_idle_enter_bm+0x27c/0x2b9 [processor] [ 4785.461463] [<c02d1ed6>] cpuidle_idle_call+0x6a/0x9c [ 4785.461468] [<c0101cc8>] cpu_idle+0x53/0x87 [ 4785.461473] [<c0346584>] rest_init+0x6c/0x6e [ 4785.461479] [<c04df74d>] start_kernel+0x286/0x28b [ 4785.461484] [<c04df037>] __init_begin+0x37/0x3c [ 4785.461487] ---[ end trace aaf8496ba3679dfb ]--- Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W.

* ath5k: warn and correct rate for unknown hw rate indexesBob Copeland2009-03-282-4/+13
| | | | | | | | | | | | | | | | | | | ath5k sets up a mapping table from the hardware rate index to the rate index used by mac80211; however, we have seen some received frames with incorrect rate indexes. Such frames normally get dropped with a warning in __ieee80211_rx(), but it doesn't include enough information to track down the error. This patch adds a warning to hw_to_driver_rix for any lookups that result in a rate index of -1, then returns a valid rate so the frame can be processed.

* ath5k: disable MIB interruptsBob Copeland2009-03-281-1/+1
| | | | | | | | | | | | | | The MIB interrupt fires whenever counters overflow; however without support for automatic noise immunity, we can sometimes get an interrupt storm. The get_stats() callback reads the counters anyway so we can disable the interrupt for now until ANI is implemented. This fixes the issue reported in http://bugzilla.kernel.org/show_bug.cgi?id=12647.

| * ath5k: discard 11g caps if reported by an ar5211 eepromHelmut Schaa2009-01-291-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | At least one ar5211 card (GIGABYTE GN-WLMA101, 168c:0012 subsystem 1458:e800) reports itself as 11g capable which seems to be a bug in the eeprom. initvals.c assumes that ar5211 is only 11b capable and thus refuses to initialize this card. Hence this patch changes the probing for 11g capabilities to discard 11g capabilities for ar5211 cards which allows this specific card to work fine in 11b and 11a modes.

| * ath5k: fix bf->skb==NULL panic in ath5k_tasklet_rxBob Copeland2009-01-291-32/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under memory pressure, we may not be able to allocate a new skb for new packets. If the allocation fails, ath5k_tasklet_rx will exit but will leave a buffer in the list with a NULL skb, eventually triggering a BUG_ON. Extract the skb allocation from ath5k_rxbuf_setup() and change the tasklet to allocate the next skb before accepting a packet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Sync qcu.c with legacy-hal * Add some more comments * Set QCU mask to save power (QCU mask controls which QCUs are attached to each DCU, we do a 1:1 mapping) TODO: Use max QCU from EEPROM, further sync with legacy-hal and sam's hal and a few more minor fixes. I think after this we are ready to implement WME on the driver part. Anyone interested ? Signed-Off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The set_key callback now seems rather odd, passing a MAC address instead of a station struct, and a local address instead of a vif struct.
