The hardware scheduler will stop using aggregation for any frame that fails LINK_QUAL_AGG_DISABLE_START_DEF times. Currently, both these constants equal 3. If iwlwifi probes a faster rate than the link supports, all frames in a (potentially tens of frames large) batch will fail IWL_HT_NUMBER_TRY times. Because this happens to be as large as LINK_QUAL_AGG_DISABLE_START_DEF, all frames will then be sent individually. This leads to a short, but performance-degrading window where the legacy stop-and-wait MAC takes over. Bounding the initial rate by (LINK_QUAL_AGG_DISABLE_START_DEF-1) attempts makes the third try use a lower rate and hence more be likely to succeed. This somewhat mitigates the above described behavior.

Secondly, the compressed block ack handling code was broken. Fix this. (1) A shift less than zero simply implies that the buffer wrapped, this is expected. Remove the incorrect comment. (2) The (agg->frame_count > (64-sh)) condition can happen if the last frame is dropped. E.g., if I send 7 frames and the 6th is received but the 7th is lost, the other side may only shift the window 6, not 7 frames since the last bit is a 0. This is perfectly fine behavior and doesn't invalidate the feedback. (3) Store the feedback from a Compressed BA in the first newly received frame, rather than the start of the window. This way it will get processed by the rate selection code. Feedback stored in a non-received frame is likely to get overwritten by the retransmission. This is based on the approach taken by minstrel_ht.

Sometimes the ACK is sent by STA for assoc response is not seen at AP side. So the AP continues to send retry assoc responses. At the STA side, since the assoc response was already forwarded to mac80211, it proceeded to channel change which in turns does chip reset. In most of the cases the chip reset was completed before max retries are reached at AP side. Hence STA can able to ACK the retried frames again. But in clear environment these retries are completed within shortspan of time. Since ath9k_htc consumes more time for hw reset, this latency is causing dissociation by AP due to max reties are reached. This issue was originally reported with Cisco Aironet 1250 AP in HT40 mode in noise free environment. Signed-off-by: Rajkumar Manoharan Signed-off-by: John W.

Since the hardware timers are actually configured in microseconds, it's better to let the driver use that unit directly. To be able to do that, the beacon interval parameter abuse for passing certain flags needs to be removed. This is easy to do, because those flags are completely unnecessary anyway. ATH9K_BEACON_ENA is ignored, ATH9K_BEACON_RESET_TSF can be replaced with calling ath9k_hw_reset_tsf from the driver directly. Signed-off-by: Felix Fietkau Signed-off-by: John W.

When the driver runs only one active AP mode interface, it still configures the hardware beacon timer for 4 (ATH_BCBUF) beacon slots slots, which causes stuck beacon detection to be reset if ath9k_hw_stoptxdma clears the stuck frames between SWBA intervals. Fix this by not resetting the missed beacon count for empty slots and multiplying the threshold not by the maximum number of beacon slots but by the configured number of beacon interfaces.

To be able to do this, it pulls in around 40 kb worth of unnecessary kernel modules (at least on a MIPS embedded device). Using arc4 directly not only eliminates those dependencies, it also makes the code smaller. Signed-off-by: Felix Fietkau Signed-off-by: John W.

Hence a lot of SET_ and RESET_ bit operation macros were used to convert the dev_cap format to 11n capability format. However the locally defined 11n ht_cap macros are not necessary as we can use IEEE80211_HT_CAP_ macros directly. The 32-bit dev_cap bitmap is added as comment to explain the mapping between firmware and 11n spec. Some unused macros and unnecessary adapter variables are also removed.

On rt2800pci this will increase the kfifo size from 512 bytes to 1024 bytes which is then able to hold the tx status for all entries in all tx queues. Furthermore, if the number of tx queues or tx entries changes in the future (use of the MGMT queue for example) the kfifo size doesn't need to be updated.

As a result we can remove the call to rt2x00queue_align_payload in the rx path and since that's the last user we can remove rt2x00queue_align_payload altogether. One advantage is that we save some alignment operations for frames that don't need to be aligned (for example beause they are not passed to the net stack).

[PATCH 105/179] rt2x00: Fix STBC transmissions to STAs with Rx STBC > 1 For STBC transmissions rt2x00 used the number of RxSTBC streams the destination STA indicates in its HT capabilities as STBC value in the TXWI. However, the legacy drivers and our own comment in rt2800.h suggest that the STBC field in the TXWI only allows a value of 0 or 1. The values 2 and 3 are reserved (probably for future devices). And indeed, STBC transmissions to STAs indicating more then 1 RxSTBC stream fail when the STBC field is set to something >1. Fix this by only setting the STBC field to 1 when STBC should be used.

Introduce a new flag TXDONE_AMPDU to indicate that this is an AMPDU subframe and pass IEEE80211_TX_STAT_AMPDU_NO_BACK to mac80211 if an AMPDU subframe failed during transmission.

The set_default_key() won't be called if wpa_supplicant uses "-Dwext" option, but it's been called if "-Dnl80211" option is specified. We can fix this issue by adding a check to return from set_default_key() if WEP key is not configured.

Since the idle mode can reuse the code that is now used in Power Save Mode (PSM), the flag psm in struct wl1251 is changed to variable station_mode to be able to distinguish between PSM and idle modes. As the station mode is different than the power power save mode command that is sent to chip, the enum wl1251_cmd_ps_mod values are used only when communicating with the chip and new enum wl1251_station_mode values are used inside the driver. Confusing comment about psm and elp relation is removed since the PSM is actually activated by putting the chip into Entreme Low Power (ELP) mode.

In terms of battery current consumption, the consumption is ~180 mA higher when the interface is up but not associated and only ~5 mA higher when associated compared to interface down and driver not loaded cases. This patch adds support for the mac80211 idle notifications. Chip is put into idle very much the same way when entering into PSM by utilizing the Extreme Low Power (ELP) mode. I.e. idle is entered by setting necessary conditions in wl1251_ps_set_mode followed by a call to wl1251_ps_elp_sleep. It seems it is just enough the authorize ELP mode followed by CMD_DISCONNECT (thanks to Kalle Valo about the idea to use it). Without disconnect command the chip remains somewhat active and stays consuming ~20 mA. Idle mode is left by same way than PSM. The wl1251_join call is used to revert the CMD_DISCONNECT. Without it association to AP doesn't work when trying second time. With this patch the interface up but not associated case the battery current consumption is less than 1 mA higher compared to interface down case.

This also helps while moving back to single STA vif from multi STA vifs, where the power save is enabled and hw has to be reconfigured with proper beacon and bssid/aid.

The host driver - * indicates DRAM locations and sizes for instruction and data images via the - * four BSM_DRAM_* registers. Once the bootstrap program loads the new program, - * the new program starts automatically. - * - * The uCode used for open-source drivers includes two programs: - * - * 1) Initialization -- performs hardware calibration and sets up some - * internal data, then notifies host via "initialize alive" notification - * (struct iwl_init_alive_resp) that it has completed all of its work. - * After signal from host, it then loads and starts the runtime program. - * The initialization program must be used when initially setting up the - * NIC after loading the driver. - * - * 2) Runtime/Protocol -- performs all normal runtime operations. This - * notifies host via "alive" notification (struct iwl_alive_resp) that it - * is ready to be used. - * - * When initializing the NIC, the host driver does the following procedure: - * - * 1) Load bootstrap program (instructions only, no data image for bootstrap) - * into bootstrap memory. Use dword writes starting at BSM_SRAM_LOWER_BOUND - * - * 2) Point (via BSM_DRAM_*) to the "initialize" uCode data and instruction - * images in host DRAM. - * - * 3) Set up BSM to copy from BSM SRAM into uCode instruction SRAM when asked: - * BSM_WR_MEM_SRC_REG = 0 - * BSM_WR_MEM_DST_REG = RTC_INST_LOWER_BOUND - * BSM_WR_MEM_DWCOUNT_REG = # dwords in bootstrap instruction image - * - * 4) Load bootstrap into instruction SRAM: - * BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START - * - * 5) Wait for load completion: - * Poll BSM_WR_CTRL_REG for BSM_WR_CTRL_REG_BIT_START = 0 - * - * 6) Enable future boot loads whenever NIC's power management triggers it: - * BSM_WR_CTRL_REG = BSM_WR_CTRL_REG_BIT_START_EN - * - * 7) Start the NIC by removing all reset bits: - * CSR_RESET = 0 - * - * The bootstrap uCode (already in instruction SRAM) loads initialization - * uCode.

The last register loaded must be the instruction - * byte count register ("1" in MSbit tells initialization uCode to load - * the runtime uCode): - * BSM_DRAM_INST_BYTECOUNT_REG = byte count | BSM_DRAM_INST_LOAD - * - * 5) Wait for "alive" notification, then issue normal runtime commands. - * - * Data caching during power-downs: - * - * Just before the embedded controller powers down (e.g for automatic - * power-saving modes, or for RFKILL), uCode stores (via PCI busmaster DMA) - * a current snapshot of the embedded processor's data SRAM into host DRAM. - * This caches the data while the embedded processor's memory is powered down. - * Location and size are controlled by BSM_DRAM_DATA_* registers. - * - * NOTE: Instruction SRAM does not need to be saved, since that doesn't - * change during operation; the original image (from uCode distribution - * file) can be used for reload. - * - * When powering back up, the BSM loads the bootstrap program. Bootstrap looks - * at the BSM_DRAM_* registers, which now point to the runtime instruction - * image and the cached (modified) runtime data (*not* the initialization - * uCode). Bootstrap reloads these runtime images into SRAM, and restarts the - * uCode from where it left off before the power-down. - * - * NOTE: Initialization uCode does *not* run as part of the save/restore - * procedure. - * - * This save/restore method is mostly for autonomous power management during - * normal operation (result of POWER_TABLE_CMD). Platform suspend/resume and - * RFKILL should use complete restarts (with total re-initialization) of uCode, - * allowing total shutdown (including BSM memory). - * - * Note that, during normal operation, the host DRAM that held the initial - * startup data for the runtime code is now being used as a backup data cache - * for modified data! If you need to completely re-initialize the NIC, make - * sure that you use the runtime data image from the uCode distribution file, - * not the modified/saved runtime data. You may want to store a separate - * "clean" runtime data image in DRAM to avoid disk reads of distribution file. - */ - -/* BSM bit fields */ -#define BSM_WR_CTRL_REG_BIT_START (0x80000000) /* start boot load now */ -#define BSM_WR_CTRL_REG_BIT_START_EN (0x40000000) /* enable boot after pwrup*/ -#define BSM_DRAM_INST_LOAD (0x80000000) /* start program load now */ - -/* BSM addresses */ -#define BSM_BASE (PRPH_BASE + 0x3400) -#define BSM_END (PRPH_BASE + 0x3800) - -#define BSM_WR_CTRL_REG (BSM_BASE + 0x000) /* ctl and status */ -#define BSM_WR_MEM_SRC_REG (BSM_BASE + 0x004) /* source in BSM mem */ -#define BSM_WR_MEM_DST_REG (BSM_BASE + 0x008) /* dest in SRAM mem */ -#define BSM_WR_DWCOUNT_REG (BSM_BASE + 0x00C) /* bytes */ -#define BSM_WR_STATUS_REG (BSM_BASE + 0x010) /* bit 0: 1 == done */ - -/* - * Pointers and size regs for bootstrap load and data SRAM save/restore. - * NOTE: 3945 pointers use bits 31:0 of DRAM address. - * 4965 pointers use bits 35:4 of DRAM address. - */ -#define BSM_DRAM_INST_PTR_REG (BSM_BASE + 0x090) -#define BSM_DRAM_INST_BYTECOUNT_REG (BSM_BASE + 0x094) -#define BSM_DRAM_DATA_PTR_REG (BSM_BASE + 0x098) -#define BSM_DRAM_DATA_BYTECOUNT_REG (BSM_BASE + 0x09C) - -/* - * BSM special memory, stays powered on during power-save sleeps. - * Read/write, address range from LOWER_BOUND to (LOWER_BOUND + SIZE -1) - */ -#define BSM_SRAM_LOWER_BOUND (PRPH_BASE + 0x3800) -#define BSM_SRAM_SIZE (1024) /* bytes */ - - /** * Tx Scheduler * @@ -319,201 +183,10 @@ * Max Tx window size is the max number of contiguous TFDs that the scheduler * can keep track of at one time when creating block-ack chains of frames. * Note that "64" matches the number of ack bits in a block-ack packet. - * Driver should use SCD_WIN_SIZE and SCD_FRAME_LIMIT values to initialize - * IWL49_SCD_CONTEXT_QUEUE_OFFSET(x) values. */ #define SCD_WIN_SIZE 64 #define SCD_FRAME_LIMIT 64 -/* SCD registers are internal, must be accessed via HBUS_TARG_PRPH regs */ -#define IWL49_SCD_START_OFFSET 0xa02c00 - -/* - * 4965 tells driver SRAM address for internal scheduler structs via this reg. - * Value is valid only after "Alive" response from uCode. - */ -#define IWL49_SCD_SRAM_BASE_ADDR (IWL49_SCD_START_OFFSET + 0x0) - -/* - * Driver may need to update queue-empty bits after changing queue's - * write and read pointers (indexes) during (re-)initialization (i.e. when - * scheduler is not tracking what's happening). - * Bit fields: - * 31-16: Write mask -- 1: update empty bit, 0: don't change empty bit - * 15-00: Empty state, one for each queue -- 1: empty, 0: non-empty - * NOTE: This register is not used by Linux driver. - */ -#define IWL49_SCD_EMPTY_BITS (IWL49_SCD_START_OFFSET + 0x4) - -/* - * Physical base address of array of byte count (BC) circular buffers (CBs). - * Each Tx queue has a BC CB in host DRAM to support Scheduler-ACK mode. - * This register points to BC CB for queue 0, must be on 1024-byte boundary. - * Others are spaced by 1024 bytes. - * Each BC CB is 2 bytes * (256 + 64) = 740 bytes, followed by 384 bytes pad. - * (Index into a queue's BC CB) = (index into queue's TFD CB) = (SSN & 0xff). - * Bit fields: - * 25-00: Byte Count CB physical address [35:10], must be 1024-byte aligned. - */ -#define IWL49_SCD_DRAM_BASE_ADDR (IWL49_SCD_START_OFFSET + 0x10) - -/* - * Enables any/all Tx DMA/FIFO channels. - * Scheduler generates requests for only the active channels. - * Set this to 0xff to enable all 8 channels (normal usage). - * Bit fields: - * 7- 0: Enable (1), disable (0), one bit for each channel 0-7 - */ -#define IWL49_SCD_TXFACT (IWL49_SCD_START_OFFSET + 0x1c) -/* - * Queue (x) Write Pointers (indexes, really!), one for each Tx queue. - * Initialized and updated by driver as new TFDs are added to queue. - * NOTE: If using Block Ack, index must correspond to frame's - * Start Sequence Number; index = (SSN & 0xff) - * NOTE: Alternative to HBUS_TARG_WRPTR, which is what Linux driver uses?

Currently, however, there are a number of places that neither do that, nor actually set the FW error bit that leads to proper restart handling, which means that in those cases things will probably just hang completely. To clean this up, make all ucode restart go through a single function, except for the cases where it's called during firmware loading. Also fix a bug in wimax coexist restart avoidance, it needs to first clear the status bits (and it has to clear the HCMD_ACTIVE one as well) and then wake up anything waiting on wait_command_queue.

I haven't done any CPU utilisation measurements, but given that the hotpaths don't use much IO it is not likely to have a negative impact; in fact, the size reduction will reduce cache pressure which possibly improves performance.

Rodriguez" Date: Tue, 5 Apr 2011 10:49:03 -0700 Subject: [PATCH 178/179] cfg80211: fix regulatory restore upon user hints When we restore regulatory settings its possible CRDA will not reply because of a bogus user entry. In this case the bogus entry will prevent any further processing on cfg80211 for regulatory domains even if we restore regulatory settings. To prevent this we suck out all pending requests when restoring regulatory settings and add them back into the queue after we have queued up the reset work. The impact of not having this applied is that a user with privileges can issue a userspace regulatory hint while we are disasocciating and this would prevent any further processing of regulatory domains.

The best we can do is accept the request, and add a delayed work item for processing failure and cancel it if we succeeed. Upon failure we restore the regulatory settings and ignore the user input.
