From 0af8bcae6f44aa440e51b1925635fb835cd68058 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 30 Apr 2010 14:08:00 -0700 Subject: iwlwifi: introduce iwl_sta_id_or_broadcast There are now five places where we need to look up the station ID, but the sta pointer may be NULL due to mac80211 passing that to indicate a certain special state. Replace all these by a new inline function, called iwl_sta_id_or_broadcast(), and add documentation about when to use it.

Address this in two ways, if the access won't sleep then just move the access into the lock, if the access can sleep then copy the needed station information to the stack to be accessed without risk of it changing while access in progress. Additionally, a number of other places access station station information without holding the sta_lock, fix those as well.

However, in other places we don't, which is especially wrong in the AP code since in that case the assoc_capability is invalid. Also, the IBSS special case is not needed since "use_short_slot" will be properly cleared, but the "assoc_capability" might be invalid (which must be the reason for the special case).

Upon an a baseband watchdog interrupt we reset the hardware, this should address corner case conditions where normal operation can stall. Enable ATH_DBG_RESET to be able to review details of the bb watchdog interrupt once it happens. If you're curious how often this happens just grep the debugfs interrupt file.

In suspend() host sleep is activated using already configured host sleep parameters through wol command, and in resume() host sleep is cancelled. Earlier priv->fw_ready flag used to reset and set in suspend and resume handler respectively. Since after suspend only host goes into sleep state and firmware is always ready, those changes in flag state are removed. Signed-off-by: Amitkumar Karwar Signed-off-by: John W.

In this patch if there were one liners where string clearly fits into the buffer, then I changed snprintf to sprintf(). It's confusing to use the return value of snprintf() as a limitter without verifying that it's smaller than size. This is what initially caught my attention here. If we use the return value of sprintf() instead future code auditors will assume we've verified that it fits already. Also I did find some places where it made sense to use the return value after we've verified that it is smaller than the buffer size. Finally the read_file_rcstat() function added an explicit NULL terminator before calling snprintf(). That's unnecessary because snprintf() will add the null terminator automatically.

In any case the spur mitigation filter was set if the srev was >= AR5K_SREV_AR5424. Spur info is available only from EEPROM versions bigger than 5.3 but but the EEPOM routines will use static values for older versions, so that should be o.k.

This counter is used to determine which frames to drop when the CMD_JOIN is executed. The driver executes CMD_JOIN multiple times upon association and sometimes disassociation, and we don't want any frames to get lost. Fix this by incrementing the session counter only when leaving idle (not every CMD_JOIN as before.) Also, remove the TX flush flag from the CMD_JOIN options.

For rt2800 reverse the calling order of rt2x00pci_write_data and rt2800pci_write_data. Currently rt2800pci_write_data calls rt2x00pci_write_data as there can be only 1 driver callback function specified by the driver. Reverse this calling order by introducing a new driver callback function, called write_tx_datadesc, which is called from the bus-specific write_tx_data functions. Preparation for futher cleanups in the skb data handling of rt2x00.

There is no need to force the separation between a buffer USB vendor request that does fit the CSR cache and one that doesn't onto the callers. This is something that the rt2x00usb_vendor_request_buff function can figure out by itself. Combine the rt2x00usb_vendor_request_buff and rt2x00usb_vendor_request_large_buff functions into a single one, as both of them were equivalent for small buffers anyway.

This improves bringup time. This depends on the analog_shiftreg configuration option, which is currently buggy. For AP mode, a delay of 100us has to be the default. For station mode, this knob has to be enabled on a per-case basis, though it is a little unclear on when to enable a delay. This can be fixed later though.

Two separate functions (radio enable/disable) are introduced, because the semantics of radio handling is just not the same as the start()/stop() callbacks. For example, the HW must not be disabled, instead, the PHY has to be disabled in radio_disable(). Also, the HW has to be reset properly in radio enable/disable and certain registers have to be programmed only once, in the start() callback. The radio_enable() routine doesn't need the PS wrappers since we set the HW power mode to AWAKE anyway before calling it. Signed-off-by: Sujith Signed-off-by: John W.

In order to prevent a full WMM queue from stopping another queue with fewer frames, this patch limits the number of queued frames to a quarter of the total available tx buffers, minus some reserved frames to be used for other purposes (e.g. beacons). Because tx buffers are reserved for frames when they're staged in software queues as well, the actual queue depth cannot be used for this, so this patch stores a reference to the tx queue in the ath_buf struct and keeps track of the total number of pending frames.

This inconsistency between the rate count and the actual number of rates in the table will leave out the final rate entry (mcs15 with half gi in ht40) while forming the valid rate indices. Not having mcs15+shortGI in ht40 will have a performance impact (on max throughput) of about 10% both in nght40 and naht40 mode.

The motivation to do this comes from a warning from lockdep which detected that we request priv->mutex while holding s_active during a sysfs request (show_statistics in the example copy pasted). The reverse order exists upon request_firmware: request_firmware which is a sysfs operation that requires s_active is run under priv->mutex. This ensures that we don't get sysfs request before we finish to request the firmware, avoiding this deadlock. ======================================================= [ INFO: possible circular locking dependency detected ] ------------------------------------------------------- cat/2595 is trying to acquire lock: (&priv->mutex){+.+.+.}, at: [] show_statistics+0x48/0x100 [iwlagn] but task is already holding lock: (s_active){++++.+}, at: [] sysfs_get_active_two+0x1d/0x50 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (s_active){++++.+}: [] __lock_acquire+0xc44/0x1230 [] lock_acquire+0x8d/0x110 [] sysfs_addrm_finish+0xe9/0x180 [] sysfs_hash_and_remove+0x4a/0x80 [] sysfs_remove_group+0x44/0xd0 [] dpm_sysfs_remove+0x15/0x20 [] device_del+0x38/0x170 [] device_unregister+0x1e/0x60 [] _request_firmware+0x29d/0x550 [] request_firmware+0x17/0x20 [] iwl_mac_start+0xb1/0x1230 [iwlagn] [] ieee80211_open+0x436/0x6f0 [mac80211] [] dev_open+0x92/0xf0 [] dev_change_flags+0x7b/0x190 [] do_setlink+0x178/0x3b0 [] rtnl_setlink+0xf9/0x130 [] rtnetlink_rcv_msg+0x1bb/0x1f0 [] netlink_rcv_skb+0x86/0xa0 [] rtnetlink_rcv+0x1c/0x30 [] netlink_unicast+0x263/0x290 [] netlink_sendmsg+0x1c8/0x2a0 [] sock_sendmsg+0xcd/0x100 [] sys_sendmsg+0x15d/0x290 [] sys_socketcall+0xeb/0x2a0 [] sysenter_do_call+0x12/0x38 -> #0 (&priv->mutex){+.+.+.}: [] __lock_acquire+0x1054/0x1230 [] lock_acquire+0x8d/0x110 [] __mutex_lock_common+0x58/0x470 [] mutex_lock_nested+0x3a/0x50 [] show_statistics+0x48/0x100 [iwlagn] [] dev_attr_show+0x29/0x50 [] sysfs_read_file+0xdd/0x190 [] vfs_read+0x9f/0x190 [] sys_read+0x42/0x70 [] sysenter_do_call+0x12/0x38 other info that might help us debug this: 3 locks held by cat/2595: #0: (&buffer->mutex){+.+.+.}, at: [] sysfs_read_file+0x35/0x190 #1: (s_active){++++.+}, at: [] sysfs_get_active_two+0x2d/0x50 #2: (s_active){++++.+}, at: [] sysfs_get_active_two+0x1d/0x50 stack backtrace: Pid: 2595, comm: cat Not tainted 2.6.33-tp-rc4 #2 Call Trace: [] ?

by moving to this approach, uCode can have more control of channel switch timing.

This means that for each TX queue, we allocate 19k/38k (an order 4 or 5 allocation on 32/64 bit respectively) just for each queue's "txb" array, which contains only the SKB pointers. However, due to the way we use these pointers only the first one can ever be assigned. When the driver was initially written, the idea was that it could be passed multiple SKBs for each TFD and attach all those to implement gather DMA. However, due to constraints in the userspace API and lack of TCP/IP level checksumming in the device, this is in fact not possible. And even if it were, the SKBs would be chained, and we wouldn't need to keep pointers to each anyway. Change this to only keep track of one SKB per TFD, and thereby reduce memory consumption to just one pointer per TFD, which is an order 0 allocation per transmit queue.

Note that this is a selective ACKnowledgement following selective retransmission; e.g., if frames 1,4-5 in a batch are ACKed then the next transmission will include frames 2-3,6-10 (7 frames). In this latter case, the Compressed BlockAck will not have all meaningful information in the low order bits -- the semantically meaningful bits of the BA will be 0x1f3 (where the low-order frame is seq 2). The driver code originally just looked at the lower (in this case, 7) bits of the BlockAck. In this case, the lower 7 bits of 0x1f3 => only 5 packets, maximum, could ever be ACKed. In reality it should be looking at all of the bits, filtered by those corresponding to packets that were actually sent. This flaw meant that the number of correctly ACked packets could be significantly underreported and might result in asynchronous state between TX and RX sides as well as driver and uCode. Fix this and also add a shortcut that doesn't require the code to loop through all 64 bits of the bitmap but rather stops when no higher packets are ACKed. In my experiments this fix greatly reduces throughput swing, making throughput stable and high. It is also likely related to some of the stalls observed in aggregation mode and maybe some of the buffer underruns observed, e.g., http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1968 http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2098 http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2018 Signed-off-by: Daniel Halperin Signed-off-by: Reinette Chatre --- drivers/net/wireless/iwlwifi/iwl-agn-tx.c | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) (limited to 'drivers/net') diff --git a/drivers/net/wireless/iwlwifi/iwl-agn-tx.c b/drivers/net/wireless/iwlwifi/iwl-agn-tx.c index 0d3e13b2442f..10a0acdb9dd4 100644 --- a/drivers/net/wireless/iwlwifi/iwl-agn-tx.c +++ b/drivers/net/wireless/iwlwifi/iwl-agn-tx.c @@ -1208,7 +1208,7 @@ static int iwlagn_tx_status_reply_compressed_ba(struct iwl_priv *priv, int i, sh, ack; u16 seq_ctl = le16_to_cpu(ba_resp->seq_ctl); u16 scd_flow = le16_to_cpu(ba_resp->scd_flow); - u64 bitmap; + u64 bitmap, sent_bitmap; int successes = 0; struct ieee80211_tx_info *info; @@ -1236,16 +1236,19 @@ static int iwlagn_tx_status_reply_compressed_ba(struct iwl_priv *priv, /* check for success or failure according to the * transmitted bitmap and block-ack bitmap */ - bitmap &= agg->bitmap; + sent_bitmap = bitmap & agg->bitmap; /* For each frame attempted in aggregation, * update driver's record of tx frame's status. */ - for (i = 0; i < agg->frame_count ; i++) { - ack = bitmap & (1ULL << i); - successes += !!ack; + i = 0; + while (sent_bitmap) { + ack = sent_bitmap & 1ULL; + successes += ack; IWL_DEBUG_TX_REPLY(priv, "%s ON i=%d idx=%d raw=%d\n", ack ?

This code aims to handle the case where the NIC retransmits failed packets from a previous batch; the status information for these packets can sometimes be inserted in the middle of a batch and are actually not in order by sequence number! (I verified this can happen with printk's in the function.) The code in question adaptively identifies the "first" frame of the batch, taking into account that it may not be the one corresponding to the first agg status report, and also handles the case when the set of sent packets wraps the 256-character entry buffer. It generates the agg->bitmap field of sent packets which is later compared to the BlockAck response from the receiver to see which frames of those sent in this batch were ACKed. A small logic error (wrapping by 0xff==255 instead of 0x100==256) was causing the agg->bitmap to be set incorrectly. Fix this wrapping code, and add extensive comments to clarify what is going on.

I'm not sure if we need to set the switchtable at the same place in ath5k_hw_reset() as it was before - it is set later thru ath5k_hw_set_antenna_mode() anyways - but i leave it there to avoid problems(?).

This indicates that it actually expects RAW (read after write) type of request, so perform that when reading ELP_CTRL instead. Also cache last written value so we know what to write when doing RAW request. Because of the above it was not possible to wake the chip from ELP power saving mode, PM had to be disabled to have the driver usable in SDIO mode. After this patch PM is functional. For backporting to 2.6.34 or earlier, this patch depends on 6c1f716e8154ee9315534782b9b1eedea0559a24, which adds the required SDIO funcion.
