Ideally this WAR is needed to recover from some rare beacon stuck during stress testing. Before the STA is associated/IBSS had started beaconing, PLL4(0x1618c) always seem to have zero even though we had configured PLL3(0x16188) to query about PLL's locking status. When we keep on polling infinitely PLL4's 8th bit(ie check for PLL locking measurements is done), machine hangs due to softlockup. fixes https://bugzilla.redhat.com/show_bug.cgi?id=811142Reported-by:

btcoex periord is converted into micro seconds during initialization and converted back to milli seconds while starting timer. As MCI code handles btcoex period in msec, lets keep the btcoex timer in msec and convert them into other form whenever needed. Signed-off-by:

Both "MAC Warm Reset" and "MCI Reset Rx" will reset GPM HW write_ptr. We should check software cached write_ptr against HW write_ptr before reset. Otherwise the pending DMA data will be lost. Signed-off-by:

Choose legacy rate as the last rate of Multi Rate Retry series if and only if the last selected rate is MCS and having higher PER rate. The current code fills a legacy rate as last one even though the previous rates in the series are having good PER value. This could limit the aggregation that affects the uplink performance.

The structure brcmf_sdio contains a number of counters that are useful for debugging. These were not available in user-space. This patch exposes them in debugfs under the filename 'counters'. Reviewed-by:

This patch adds debugfs support to brcmfmac. It provide helper functions to setup the debugfs folder structure for the driver, which has following hierarchy: <debugfs_mount>/brcmfmac/<dev_name>/ ie.: /sys/kernel/debug/brcmfmac/mmc0:0001:2/ The new source file provides functions to create and remove the two folders and a function to retrieve the device-specific folder so files can be created in it.

This flow can actually happen due to a corner case in mac80211: the station is deleted before we get a chance to reclaim all the packets in flight in AGG queue. The tid_data for this station is zeroed, and we lose the match with the Tx queue. Signed-off-by:

Since request_module_nowait() can't be backported use request_module() instead -- we don't need the asynchronous behaviour of request_module_nowait() here since we're running in the firmware request work struct. Tested-by:

For AGG queues, we must match between the WiFi sequence number and the TFD number. This is a HW (SCD) requirement. This is a take two of my iwlwifi: add debug in Tx path in AGG flow This will allow us to catch bad cases in which the packets aren't in the right place on the ring. which disappeared during code move.

In fragmentation we don't update the write pointer of the HW immediately. So we shouldn't modify the timer in that case. Signed-off-by:

When the driver is built into the kernel instead of a module when the system boots it results in a panic. The order things are built in results in their initialization order when built into the kernel. Wifi has to be initialized before mvm or dvm. Reviewed-by:

This locking isn't needed. The only locking we need is when we access prph registers but there is already a separate lock for that. Since we haven't returned from the mac80211's IEEE80211_AMPDU_TX_OPERATIONAL ampdu_action, we cannot receive any Tx frame for that sta / tid while enabling the queue. Signed-off-by:

Add locking to the dynamic loading code to prevent corrupting the list if multiple device ever init at the same time (which cannot happen for multiple PCI devices, but could happen when different busses init concurrently.) Also remove a device from the list when it stops so the list isn't left corrupted, including a fix from Don to not crash when it was never added. Reviewed-by:
