The way it works is described in comments in the code, but basically the driver just has to pass down all the mac80211 requests and do accounting on agg/non-agg queues properly. For older firmware, this doesn't change anything as it ignores the fields used by the new firmware, and we only advertise uAPSD support when the firmware does.

Use predefined filters, and configure them for each associated station vif. There is no need to optimize and attach the same filter to multiple vifs, as a following patch will configure each filter to have per-vif unique values.

It involves the firmware - the driver needs to send a list of commands to the firmware before entering this state. Wake up from d0i3 also requires a few commands to the firmware. The trigger to enter D0i3 is an idle timeout that will be implemented later and will most probably rely on RUNTIME_PM infrastructure. In order to prevent entrance to D0i3 in critical flows, we implement here a reference infrastructure. When a ref is taken, we can't enter D0i3. PCIe does't support D0i3.

This means that we need to add a state to remember what is our d0i3 state and make sure that only d0i3 exit commands can be sent. Add flags to CMD_ flags and transport status for this purpose. Commands with CMD_HIGH_PRIO set are queued at the head of the command queue, behind other high priority commands. Commands with CMD_SEND_IN_IDLE set can be sent while the transport is idle (without taking rpm reference). Commands with CMD_MAKE_TRANS_IDLE set indicate that command completion should mark the transport as idle (and release the bus). Commands with CMD_WAKE_UP_TRANS set instruct the transport to exit from idle when this command is completed. The transport is marked as idle (STATUS_TRANS_IDLE) when the FW enters D0i3 state. This bit is cleared when it enters D0 state again. Process only commands with CMD_SEND_IN_IDLE flag while the transport is idle. Other enqueued commands will be processed only later, right after exiting D0i3.

Even device power save (as opposed to vif power management) must be disabled in certain circumstances (monitor vif). Refactor the current code to make this clearer by defining a function that explicitely computes these constraints.

When the RSSI attribute was added, however, this was broken and currently wpa_supplicant adds that attribute in its own matchset; however, it doesn't intend that to mean that anything that passes the RSSI filter should be passed to the host, instead it wants it to mean that everything needs to also have higher RSSI. This is semantically problematic because we have a list of filters like [ SSID1, SSID2, SSID3, RSSI ] with no real indication which one should be OR'ed and which one AND'ed. To fix this, move the RSSI filter attribute into each matchset. As we need to stay backward compatible, treat a matchset with only the RSSI attribute as a "default RSSI filter" for all other matchsets, but only if there are other matchsets (an RSSI-only matchset by itself is still desirable.) To make driver implementation easier, keep a global min_rssi_thold for the entire request as well. The only affected driver is ath6kl. I found this when I looked into the code after Raja Mani submitted a patch fixing the n_match_sets calculation to disregard the RSSI, but that patch didn't address the semantic issue.

With the current approach if another cell having the same BSSID (but using a different channel) exists then cfg80211 picks up the wrong BSS object. The result is a mismatching channel configuration between cfg80211 and the driver, that can lead to any sort of problem. The issue can be triggered by having an IBSS sitting on given channel and then asking the driver to create a new cell using the same BSSID but with a different frequency. By passing the channel to cfg80211_get_bss() we can solve this ambiguity and retrieve/create the correct BSS object. All the users of cfg80211_ibss_joined() have been changed accordingly. Moreover WARN when cfg80211_ibss_joined() gets a NULL channel as argument and remove a bogus call of the same function in ath6kl (it does not make sense to call cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

But since it is masked with 0xfff earlier, the codepath will not be executed. The earlier case where all values above 0x800 were considered invalid is incorrect, since the HW can return valid values between 0x800 and 0xfff.

It is known to be buggy and has less than optimal performance in real-world environments compared with minstrel. The only reason that it was kept when we made the switch to minstrel as default was that it showed higher throughput numbers in a clean/ideal environment. This is no longer the case and minstrel can push ath9k to the same throughput levels. In TCP, with 3-stream cards, more than 295 Mbps can be obtained in open air, with 2-stream cards, 210 Mbps is easily reached. To test performance issues, instead of using a broken rate control module, it is better to use the fixed-rate interface provided by mac80211 anyway. The ath9k RC has not received any bug fixes in years and is just bit-rotting away - this patch removes it. Signed-off-by: Sujith Manoharan Signed-off-by: John W.

'rssi' field won't be there in this buffer for extended scan.

Host will send next scan command when all the events are received. Legacy scan sometimes truncates scan results in a noisy environment due to buffer length limitation. This issue is addressed in extended scan. Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.

Moreover its not possible to understand the intent of passing 0 as the size to dma unmap. The intent of this driver is unmap the entire skb buffer. The only way to ensure that the size matches on unmap is to store both the dma address and the size in the skb ca field. Introduce a mwifiex_dma_mapping structure which tracks the dma address and the size. Additionally, provide a mwifiex_unmap_pci_memory() that utilizes the new structure. This also provide symmetry within the internal API. Signed-off-by: Aaron Durbin Reviewed-by: Paul Stewart Reviewed-by: Avinash Patil Signed-off-by: Bing Zhao Signed-off-by: John W.

However, that is not true. The mwifiex_check_ps_cond() will send a sleep command to the card without having adapter->curr_cmd set. Within the workqueue's state machine the adapter's state would be set to allow commands (curr_cmd = NULL && cmd_sent = false) after having receieved the response from the sleep command. The card->cmd_buf would then be overridden with the new command but the first command's skbuff was not unmapped. This leaks mapped skbuffs when a bounce buffer is employed. To rectify this unmap the card->cmd_buf when the response is received from the card instead of waiting for the cmdrsp_complete() callback.

It may happen that once TDLS link is setup, packets sent from station to peer on direct link get delivered before traffic from AP arrives at peer station. This results into packet reordering issue at peer station. To avoid this, we hold data packets destined to TDLS peer during TDLS setup. These packets are moved to temperory TDLS TX queue. Upon successful TDLS setup, they are moved to RA list created for this peer. Upon failure, packets are moved back to AP's RA list for that particular TID.

Get ready for it by configuring wl->num_links per-hw, instead of using the const WL12XX_MAX_LINKS. However, continue using WLCORE_MAX_LINKS in order to simplify structs declarations (we use it in multiple bitmaps, and converting them to dynamic arrays is just cumbersome).

Some modifications were done to the driver-fw api in order to support multiple APs. Additionally, some of the consts (such as max stations, max links and max RX BA sessions) were changed.

Supplicant determines if the TDLS peer is VHT/HT/WMM capable based on the presence of the respective IEs in the received TDLS Setup Response frame. The host driver should not need to parse the received TDLS Response frame and thus, should be able to rely on the supplicant to indicate the capability of the peer through additional flags while transmitting the TDLS Setup Confirmation frame through tdls_mgmt operations.

The last two are probably done because some hardware does not support them. The first is probably a mistake. This patch adds the missing set_hw_reg call. For PCI support, rx_conf is not touched directly. Instead, get_hw_reg is used to abstract between receive_config (for PCI) and rx_conf (for USB). This was tested on a 10ec:8176 Realtek RTL8188CE (according to the label on the mini-PCIe card). Before this patch, `iw wlan0 set monitor otherbss` did not capture frames from other BSS's. After this patch, it does print packets. Tested-by: Peter Wu Signed-off-by: Peter Wu Acked-by: Larry Finger Signed-off-by: John W.

Update rt2800usb.c to use INIT_WORK() instead of PREPARE_WORK(). As the work item isn't in active use during rt2800usb_probe_hw(), this doesn't cause any behavior difference.

By skipping it it's possible to easily submit scatter-gather to the pci hif for reduced host cpu load and improved performance. The new approach uses dma pool to store the following metadata for each tx request: * msdu fragment list * htc header * htt tx command The htt tx command contains a msdu prefetch. Instead of copying it original mapped msdu address is used to submit a second scatter-gather item to hif to make a complete htt tx command. The htt tx command itself hands over dma mapped pointers to msdus and completion of the command itself doesn't mean the frame has been sent and can be unmapped/freed. This is why htc tx completion is skipped for htt tx as all tx related resources are freed upon htt tx completion indication event (which also implicitly means htt tx command itself was completed). Since now each htt tx request effectively consists of 2 copy engine items CE_HTT_H2T_MSG_SRC_NENTRIES is updated to allow maximum of TARGET_10X_NUM_MSDU_DESC msdus being queued. This keeps the tx path resource management simple.

Using rx_ring.lock and tx_lock allows to use less heavy bh spinlock functions and moving locking upwards allows to toggle spinlocks less often.

Since quite some time now it is no longer necessary. The other premise was to batch up tx/rx completions to take advantage of hot caches. However frame tx/rx completion indications come in on a single pipe already so they are already batched up. More meaningful batching is done in HTT itself. This means PCI completion is no longer necessary to keep around. It just wastes memory, cycles and SLOC.

Currenly if the allocation fails, the driver's allocation routine exits immediatly but it will return zero (success) anyway. In this way the driver will continue initialization with buggy pointers around. This patch makes the driver's allocation routine to return an error value and to print a complaint message when skb allocation fails. In this way its caller will not go further, avoinding the driver to successfully load, and preventing dereferencing buggy pointers. An hint is thus printed about why the driver failed.

In order to detect such behavior, mwifiex must note the starting sequence number given during the ADDBA request. If the first received sequence number after the ADDBA falls outside the receive window for this TID but after the the ADDBA starting sequence number, we can assume that this AP has reset its sequence number during the ADDBA. In this case we must adjust the input window backward to incorporate this received sequence number instead of ignoring it. Otherwise, we could fail to successfully retrieve an arbitrarily large number of downstream frames at the beginning of the block-ACK session.

The main reason for not disabling weak signal detection in AP mode is that typically beacon RSSI is used to track whether it is needed to boost range, and this is unavailable in AP mode for obvious reasons. The problem with not disabling weak signal detection is that older chipsets are very sensitive to high PHY error counts. When faced with heavy noise, this can lead to an excessive amount of "Failed to stop TX DMA" errors in the field. Signed-off-by: Felix Fietkau Signed-off-by: John W.

Even when there is no traffic. This adds stress on the memory manager. The handling of compound pages is also less trivial for the memory manager and not using them will make the allocation code run faster although I didn't really measure. Eric also pointed out that having huge buffers with little data in them is not very nice towards the TCP stack since the truesize of the skb is huge. This doesn't allow TCP to have a big Rx window.

Enable LP XTAL to avoid HW bug where device may consume much power if FW is not loaded after device reset. LP XTAL is disabled by default after device HW reset. Configure device's "persistence" mode to avoid resetting XTAL again when SHRD_HW_RST occurs in S3. 2. Add methods to access SHR (shared block memory space) directly from PCI bus w/o need to power up MAC HW. Shared internal registers (e.g. SHR_APMG_GP1, SHR_APMG_XTAL_CFG)can be accessed directly from PCI bus through SHR arbiter even when MAC HW is powered down. This is possible due to indirect read/write via HEEP_CTRL_WRD_PCIEX_CTRL (0xEC) and HEEP_CTRL_WRD_PCIEX_DATA (0xF4) registers. Use iwl_write32()/iwl_read32() family to access these registers.

Instead of that, allow it to return whether or not the device should be turned off, this gets rid of the call indirection and will help make the API more consistent when we go back to non-threaded interrupts again for PCIe.

The purpose of this calibration (which isn't really a calibration), is to measure the isolation between the antennas and that can give us useful information for the Coex modules. With this information, we can tune the LookUpTables (LUTs) that define the BT / WiFi contention policy. The LUTs currently contain dummy values - but they will be updated soon. While at it, change the current code to stop duplicate the host command while sending. This was needed back then, when the command was short enough to be allocated on the stack. Since then, the command grew a lot and is now allocated on the heap - hence we can use the NOCOPY option instead.

Since now the driver supports only rtl8185 and rtl8180 cards, if "r8185" variable is zero then the card is implicitly assumed to be a rtl8180. Now I'm preparing to add support for a third card type (rtl8187se). This patch changes the "r8185" flag with an enum variable to explicitly indicate which card type we have. I'm submitting this this patch now, even if I still have to submit other patches that not pertain with rtl8187se support, because IMHO it's not worth rebasing them on the current code, using r8185 flag, and then changing them back again nearly immediately. BTW if someone feels I really should do this, please tell me.. Signed-off-by: Andrea Merello Signed-off-by: John W.

A deadlock happens because we call ieee80211_unregister_hw() from the .start callback of struct ieee80211_ops.

It assumes that the INI values contain a baseline value that is usable as reference from which to increase/decrease based on the noise immunity value. On older chips, the differences are bigger and especially AR5008/AR9001 are configured to much more sensitive values than what is useful. Improve ANI behavior by reverting to the absolute values used in the previous implementation (expressed as a simple formula instead of the old table).

However, in order to make sure we use correct seq num for tx frames, we need to defer any outgoing frames, and re-enqueue them only after the seq num is configured correctly. Sync new Tx aggregations with D0i3 so that the correct seq num is used for them. Wait synchronously for D0i3 exit before starting a new Tx agg.

This buffer is kept aside until it is dumped through debugfs. Once an external application fetched the data, the buffer is freed and a new buffer can be allocated in case another assert occurs. A udev event is sent to trigger an external application. A simple rule like: DRIVER=="iwlwifi", ACTION=="change", RUN+="/sbin/dump_sram.sh" can fetch the data from debugfs. Here is my dump_sram.sh: phyname=$(basename ${DEVPATH}) date=$(date +%F_%H_%M) filename=/var/log/iwl-sram-${phyname}-${date}.bin cat /sys/kernel/debug/ieee80211/${phyname}/iwlwifi/iwlmvm/fw_error_dump > ${filename} The current SRAM size is 80KB so, currently: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin -rw-r--r-- 1 emmanuel emmanuel 81K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin and after compression: $ ls -lh iwl-sram-phy0-2014-03-16_13_14.bin.xz -rw-r--r-- 1 emmanuel emmanuel 13K Mar 16 13:15 iwl-sram-phy0-2014-03-16_13_14.bin.xz Signed-off-by: Emmanuel Grumbach --- drivers/net/wireless/iwlwifi/mvm/debugfs.c | 53 ++++++++++++ drivers/net/wireless/iwlwifi/mvm/fw-error-dump.h | 106 +++++++++++++++++++++++ drivers/net/wireless/iwlwifi/mvm/mac80211.c | 9 ++ drivers/net/wireless/iwlwifi/mvm/mvm.h | 8 +- drivers/net/wireless/iwlwifi/mvm/ops.c | 47 +++++++++- drivers/net/wireless/iwlwifi/mvm/utils.c | 27 +++--- 6 files changed, 230 insertions(+), 20 deletions(-) create mode 100644 drivers/net/wireless/iwlwifi/mvm/fw-error-dump.h (limited to 'drivers/net/wireless') diff --git a/drivers/net/wireless/iwlwifi/mvm/debugfs.c b/drivers/net/wireless/iwlwifi/mvm/debugfs.c index 21ef8daede05..cf1fa498e53e 100644 --- a/drivers/net/wireless/iwlwifi/mvm/debugfs.c +++ b/drivers/net/wireless/iwlwifi/mvm/debugfs.c @@ -65,6 +65,7 @@ #include "iwl-io.h" #include "iwl-prph.h" #include "debugfs.h" +#include "fw-error-dump.h" static ssize_t iwl_dbgfs_tx_flush_write(struct iwl_mvm *mvm, char *buf, size_t count, loff_t *ppos) @@ -117,6 +118,51 @@ static ssize_t iwl_dbgfs_sta_drain_write(struct iwl_mvm *mvm, char *buf, return ret; } +static int iwl_dbgfs_fw_error_dump_open(struct inode *inode, struct file *file) +{ + struct iwl_mvm *mvm = inode->i_private; + int ret; + + if (!mvm) + return -EINVAL; + + mutex_lock(&mvm->mutex); + if (!mvm->fw_error_dump) { + ret = -ENODATA; + goto out; + } + + file->private_data = mvm->fw_error_dump; + mvm->fw_error_dump = NULL; + kfree(mvm->fw_error_sram); + mvm->fw_error_sram = NULL; + mvm->fw_error_sram_len = 0; + ret = 0; + +out: + mutex_unlock(&mvm->mutex); + return ret; +} + +static ssize_t iwl_dbgfs_fw_error_dump_read(struct file *file, + char __user *user_buf, + size_t count, loff_t *ppos) +{ + struct iwl_fw_error_dump_file *dump_file = file->private_data; + + return simple_read_from_buffer(user_buf, count, ppos, + dump_file, + le32_to_cpu(dump_file->file_len)); +} + +static int iwl_dbgfs_fw_error_dump_release(struct inode *inode, + struct file *file) +{ + vfree(file->private_data); + + return 0; +} + static ssize_t iwl_dbgfs_sram_read(struct file *file, char __user *user_buf, size_t count, loff_t *ppos) { @@ -1042,6 +1088,12 @@ MVM_DEBUGFS_WRITE_FILE_OPS(fw_nmi, 10); MVM_DEBUGFS_READ_WRITE_FILE_OPS(scan_ant_rxchain, 8); MVM_DEBUGFS_READ_WRITE_FILE_OPS(d0i3_refs, 8); +static const struct file_operations iwl_dbgfs_fw_error_dump_ops = { + .open = iwl_dbgfs_fw_error_dump_open, + .read = iwl_dbgfs_fw_error_dump_read, + .release = iwl_dbgfs_fw_error_dump_release, +}; + #ifdef CONFIG_IWLWIFI_BCAST_FILTERING MVM_DEBUGFS_READ_WRITE_FILE_OPS(bcast_filters, 256); MVM_DEBUGFS_READ_WRITE_FILE_OPS(bcast_filters_macs, 256); @@ -1064,6 +1116,7 @@ int iwl_mvm_dbgfs_register(struct iwl_mvm *mvm, struct dentry *dbgfs_dir) MVM_DEBUGFS_ADD_FILE(sta_drain, mvm->debugfs_dir, S_IWUSR); MVM_DEBUGFS_ADD_FILE(sram, mvm->debugfs_dir, S_IWUSR | S_IRUSR); MVM_DEBUGFS_ADD_FILE(stations, dbgfs_dir, S_IRUSR); + MVM_DEBUGFS_ADD_FILE(fw_error_dump, dbgfs_dir, S_IRUSR); MVM_DEBUGFS_ADD_FILE(bt_notif, dbgfs_dir, S_IRUSR); MVM_DEBUGFS_ADD_FILE(bt_cmd, dbgfs_dir, S_IRUSR); if (mvm->fw->ucode_capa.flags & IWL_UCODE_TLV_FLAGS_DEVICE_PS_CMD) diff --git a/drivers/net/wireless/iwlwifi/mvm/fw-error-dump.h b/drivers/net/wireless/iwlwifi/mvm/fw-error-dump.h new file mode 100644 index 000000000000..58c8941c0d95 --- /dev/null +++ b/drivers/net/wireless/iwlwifi/mvm/fw-error-dump.h @@ -0,0 +1,106 @@ +/****************************************************************************** + * + * This file is provided under a dual BSD/GPLv2 license.

Set the following scan parameters for both immediate and scheduled scan: - passive scan fragment duration = 20ms - out-of-channel time = 70ms - suspend time = 105ms Restructure channel's active/passive dwell time configuration to better suit the above change. The idea is that under low latency traffic passive scan is fragmented, i.e. that dwell on a particular channel will be fragmented. Each fragment dwell time is 20ms and fragments period is 105ms. Skipping to next channel will be delayed by the same period (105ms). So suspend_time parameter describing both fragments and channels skipping periods is set to 105ms. This value is chosen so that overall passive scan duration will not be too long. Max_out_time in this case is set to 70ms, so for active scanning operating channel will be left for 70ms while for passive still for 20ms (fragment dwell).

The driver uses just one TX queue, and declare to mac80211 to support just one queue, but it allocates coherent memory for all queues. Furthermore the TX is code is written assumimg four queues exists, and even if we decide to enable more queues in future, its mapping rule to mac80211 is fixed. This means we have memory waste on rtl8180/rtl8185, and we have also not enough flexibility to add support for boards (rtl8187se) that will use more queues. This patch changes things in order to allocate coherent memory only for the queues effectively used and it make it possible to specify how to map hardware queues on mac80211 queues, that will be used by rtl8187se code as soon it will be merged. Note: even if the beacon queue is currently unused, this should change, so I kept it. Signed-off-by: Andrea Merello Signed-off-by: John W.

Register are thus accessed using a pointer of this type. All registers are packed toghether, and only small gaps are present. However Rtl8187se has also some "sparse" registers, very far from the "main register block". It could be possible to access them by simply declare huge reserved blocks inside the register struct (and this causes NO memory waste). However, for various reasons, access to those "far" registers is done with special dedicated macros, without declaring them in the register struct. This is done in an intricate manner, that makes code less readable and caused static analisys tool to produce warnings. This patch keeps the "macro" mechanism, but it changes its implementation in a simplier and more straightforward way. Signed-off-by: Andrea Merello Signed-off-by: John W.
