* iwlwifi: a few fixes in licenseEmmanuel Grumbach2013-03-061-1/+1
| | | | | | | | | | 7000.c was released as GPL only by mistake: it should be dual licensed - GPL / BSD. The file that contains the license in the kernel is COPYING and not LICENSE.GPL.

* iwlwifi: use threaded interrupt handlerJohannes Berg2013-02-051-4/+6
| | | | | | | | | | | | | | | | | | | | | | With new transports coming up, move to threaded interrupt handling now. This has the advantage that we can use the same locking scheme with all different transports we may need to implement. Note that the TX path obviously still runs in a tasklet, so some spin_lock() calls need to change to spin_lock_bh() calls to properly lock out the TX path. In my test on a Calpella platform this has no impact on throughput or latency. Also add lockdep annotations to avoid lockups due to catch sending synchronous commands or using locks that connect with them from the irq thread.

* iwlwifi: rework the iwlwifi debugfs structureMeenakshi Venkataraman2012-07-261-1/+2
| | | | | | | | | | | | | | | | The generic part of the driver now creates all debugfs directories. It creates a root directory directly in the the root of the debugfs filesystem and within that directories for each device, named after the device ID of the devices iwlwifi is attached to. In the cfg80211/mac80211 directory there's now a link to the toplevel iwlwifi debugfs directory to make it easier to find the debugfs files.

* iwlwifi: comment context requirements of the op_modeEmmanuel Grumbach2012-06-181-7/+9

* iwlwifi: remove extern opmode ops declarationsJohannes Berg2012-06-061-5/+0

* iwlwifi: implement dynamic opmode loadingDon Fry2012-06-051-0/+3
| | | | | | | | | | | | | This is the next step in splitting up the driver, making the uCode API dependent pieces of it live in separate modules. Right now there's only one so it's not user-selectable, but we're actively working on more.

* iwlwifi: move queue mapping out of transportJohannes Berg2012-04-091-8/+9
| | | | | | | | | | | | | | | | The queue mapping is not only dynamic, it is also dependent on the uCode, as we can already see today with the dual-mode and non-dual-mode being different. Move the queue mapping out of the transport layer and let the higher layer manage it. Part of the transport configuration is how to set up the queues.

* iwlwifi: virtualize command queue full behaviourJohannes Berg2012-03-071-0/+7
| | | | | | | | | | | | | | | | When the command queue is full, the transport will return -ENOSPC, but the reaction to that depends on the op_mode. Virtualize that, the DVM op_mode checks for CT-kill and restarts the hardware otherwise. We may be able to get rid of this callback by putting the behaviour check into the wrapper but that needs more careful evaluation.

* iwlwifi: split out firmware storeJohannes Berg2012-03-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | Through the driver, struct iwl_fw will store the firmware. Split this out into a separate file, iwl-fw.h, and make all other code use it. To do this, also move the log pointers into it, and remove the knowledge of "nic" from everything. Now the op_mode has a fw pointer, and (unfortunately) for now the shared data also needs to keep one for the transport to access dump the error log -- I think that will move later. Since I wanted to constify the firmware pointers, some more changes were needed.

* iwlwifi: don't pass iwl_rx_mem_buffer to upper layersJohannes Berg2012-03-061-3/+3
| | | | | | | | | | | | | | | | struct iwl_rx_mem_buffer implementation details (DMA address, list pointers) that the upper layers don't need. Introduce iwl_rx_cmd_buffer that is passed upstream and only contains the needed data (the page). Additionally, access this data only via accessor functions, allowing us to change the implementation in the future. These accessors are rxb_addr() (as before) and rxb_steal_page() to take ownership of the data.
