This trans_ops->stop_hw leaves the RFKILL interrupt enabled, we can call that one instead of enable_rfkill_int. By that, we reduce the numbers of acceesses to the NIC from the upper layers. Signed-off-by:

Now there is only one transport function that launch a specific fw: trans_ops->start_fw. This one replaces trans_ops->start_device and trans_ops->kick_nic. The code that actually loads the fw to the device has been moved to the transport specific code. Signed-off-by:

From now on, the transport layer in charge of providing access to the device. So change all the driver to give a pointer to the transport to all the low level functions that actually access the device. Signed-off-by:

Change the way we alloc the transport on the way. Since the transport is allocated from a bus specific area, we can give the bus specific parameters (i.e. pci_dev for PCI) to the transport. This will be useful when the bus layer will be killed. Signed-off-by:

This patch addresses a kernel bugzilla report and two recent mail threads. The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by:

Whenever the PAN (P2P) context is active, it has timers in the uCode that prevent sleep, so scanning can't be out of channel for more than the beacon interval programmed into the device. Before this patch, a full scan including any passive channels when P2P was active would stall forever because it wouldn't find time to execute the passive requests (for default beacon intervals of 100 TU.)

Fix multiple bugs in event tracing: 1) If you enable uCode tracing with the device down, it will still attempt to access the device and continuously log "MAC is in deep sleep!" errors. Fix this by only starting logging when the device is actually alive. 2) Now you can set the flag when the device is down, but logging doesn't happen when you bring it up. To fix that, start logging when the device comes alive. This means we don't log before -- we could do that but I don't need it right now. 3) For some reason we read the error instead of the event log -- use the right pointer. 4) Optimise SRAM reading of event log header. 5) Fix reading write pointer == capacity, which can happen due to racy SRAM access 6) Most importantly: fix an error where we would try to read WAY too many events (like 2^32-300) when we read the wrap counter before it is updated by the uCode -- this does happen in practice and will cause the driver to hang the machine. 7) Finally, change the timer to 10ms instead of 100ms as 100ms is too slow to capture all data with a normal event log and with 100ms the log will wrap multiple times before we have a chance to read it.

Unted the assumption that the sta struct is still accessible before the synchronize_rcu call we should move the num_sta_ps counter decrement after synchronize_rcu to avoid incorrect decrements if num_sta_ps. Signed-off-by:

If the driver blocked this specific STA with the help of ieee80211_sta_block_awake we won't clear WLAN_STA_PS_STA later but still decrement num_sta_ps. Hence, the next data frame from this STA will trigger ap_sta_ps_end again and also decrement num_sta_ps again leading to an incorrect num_sta_ps counter. This can result in problems with powersaving clients not waking up from PS because the TIM calculation might be skipped due to the incorrect num_sta_ps counter. Signed-off-by:

Helmut Schaa authored
When WLAN_STA_PS_DRIVER is set by ieee80211_sta_block_awake the num_sta_ps counter is not incremented. Hence, we shouldn't decrement it in __sta_info_destroy if only WLAN_STA_PS_DRIVER is set. This could result in an incorrect num_sta_ps counter leading to strange side effects with associated powersaving clients. Fix this by only decrementing num_sta_ps when WLAN_STA_PS_STA was set before.

In the future, when we start notifying drivers, state transitions could potentially fail. To make it easier to distinguish between programming bugs and driver failures: * rename sta_info_move_state() to sta_info_pre_move_state() which can only be called before the station is inserted (and check this with a new station flag). * rename sta_info_move_state_checked() to just plain sta_info_move_state(), as it will be the regular function that can fail for more than just one reason (bad transition or an error from the driver) This makes the programming model easier -- one of the functions can only be called before insertion and can't fail, the other can fail.
