* mwl8k: fix firmware command serialisationLennert Buytenhek2009-08-201-65/+89
| | | | | | | | | | | | | | | | | | | | | | | | The current mwl8k_priv->fw_lock spinlock doesn't actually protect against multiple commands being submitted at once, as it is not kept held over the entire firmware command submission. And since waiting for command completion sleeps, we can't use a spinlock anyway. To fix mwl8k firmware command serialisation properly, we have the following requirements: - Some commands require that the packet transmit path is idle when the command is issued. (For simplicity, we'll just quiesce the transmit path for every command.) - There are certain sequences of commands that need to be issued to the hardware sequentially, with no other intervening commands. This leads to an implementation of a "firmware lock" as a mutex that can be taken recursively, and which is taken by both the low-level command submission function (mwl8k_post_cmd) as well as any users of that function that require issuing of an atomic sequence of commands, and quiesces the transmit path whenever it's taken.

* mwl8k: mwl8k_queue_work() cleanupLennert Buytenhek2009-08-201-171/+33
| | | | | | | | | | | | | | | | | Delete most of the mwl8k_work_struct fields and options, since most of them are unused or never changed from their defaults: - We always use priv->config_wq, so delete the wqueue argument from mwl8k_queue_work(). - MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all callers sleep for request completion, so sleep unconditionally. - MWL8K_WQ_FREE_WORKSTRUCT is never used. - MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally. - timeout_ms/txwait_attempts/tx_timeout_ms are never changed from their defaults, so just hardcode these in the workqueue worker. - step is never used.

* mwl8k: don't touch 'command done' interrupt during firmware loadLennert Buytenhek2009-08-201-23/+1
| | | | | | | | | | | Since firmware load commands don't generate 'command done' interrupts like normal commands do, polling for command done interrupts just unnecessarily slows down the firmware load process. Removing this bit of code speeds up loading a typical firmware image from 840 msec to 180 msec. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

* mwl8k: dma header manipulations can't failLennert Buytenhek2009-08-201-70/+13
| | | | | | | | | | | | | | | Adding and removing the DMA header that the mwl8k hardware requires on tx and provides on rx can never fail, since we are guaranteed to have enough headroom on the tx path to expand the packet, and we only ever shrink the packet on the rx path. (And on both paths we are guaranteed to be the only user of the skb we are handling.) This allows removing all of the skb clone handling in the tx and tx reclaim paths, and eliminates error checks in both the tx and rx paths, simplifying the code a bit more.

| | | | | | | | | | There is no need to check for NL80211_IFTYPE_MONITOR in ->add_interface(), as this function is never called for monitor interfaces.

* mwl8k: fix mwl8k_configure_filter() parameter lifetime issueLennert Buytenhek2009-08-201-68/+39
| | | | | | | | | | | | | | | | | | mwl8k_configure_filter() passes pointers to total_flags and the multicast address list to a workqueue function, while there is no guarantee that those pointers will still be valid by the time the workqueue function runs. Solve this by passing total_flags by value, and by passing an already built multicast address setup command packet to the workqueue function so that we don't have to look at the multicast address list itself outside of mwl8k_configure_filter(). Also, since ->configure_filter() can sleep now, wait synchronously for the worker to finish. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

* mac80211: allow configure_filter callback to sleepJohannes Berg2009-08-201-7/+27
| | | | | | | | | | | | | | | | | | | | | Over time, a whole bunch of drivers have come up with their own scheme to delay the configure_filter operation to a workqueue. To be able to simplify things, allow configure_filter to sleep, and add a new prepare_multicast callback that drivers that need the multicast address list implement. This new callback must be atomic, but most drivers either don't care or just calculate a hash which can be done atomically and then uploaded to the hardware non-atomically. A cursory look suggests that at76c50x-usb, ar9170, mwl8k (which is actually very broken now), rt2x00, wl1251, wl1271 and zd1211 should make use of this new capability.

* | mac80211: push rx status into skb->cbJohannes Berg2009-07-101-1/+2
|/ | | | | | | | | | | | | | | Within mac80211, we often need to copy the rx status into skb->cb. This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)). Each driver can now be optimised on its own schedule. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
