2012-04-10iwlwifi: move valid_contexts to privJohannes Berg1-2/+2
No other component is accessing it any more, so it can move to the correct place in priv. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-10iwlwifi: move queue mapping out of transportJohannes Berg1-4/+160
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.

2012-03-12iwlwifi: move wait_command_queue from shared to transMeenakshi Venkataraman1-2/+0
This wait queue really belongs to the transport layer, as it is used for sending synchronous commands to the HW. However, only op_mode knows about errors and exceptional conditions, so make this queue accessible by the op_mode.

2012-03-12iwlwifi: abstract out missing SEQ_RX_FRAME workaroundJohannes Berg1-0/+10
Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround warning with a statistics notification, this means we can't just remove it as we'd hoped. Abstract it out so that the higher layer can configure this as a kind of "filter" in the transport.

2012-03-09iwlwifi: restore PAN supportEmmanuel Grumbach1-29/+30
in iwlwifi: move setting up fw parameters Meenakshi moved code up to configure the transport layer, but this code read the sku before it was set (from the EEPROM). This killed P2P. Only the ucode_flags are needed to configure the transport layer, not the sku which _must_ be set after the EEPROM is read. We need to reconfigure the transport in case the EEPROM disabled PAN support. This is not the nicest thing to do, but we have no choice. Document that we are allowed to configure the transport several times before start_fw, but not after.

2012-03-08iwlwifi: cleanup/fix memory barriersStanislaw Gruszka1-1/+0
wmb(), rmb() are not needed when writel(), readl() are used as accessors for MMIO. We use them indirectly via iowrite32(), ioread32(). What is needed mmiowb(), for synchronizing writes coming from different CPUs on PCIe bridge (see in patch comments). This fortunately is not needed on x86, where mmiowb() is just defined as compiler barrier. As iwlwifi devices are most likely not used on anything other than x86, this is not so important fix.

2012-03-08iwlwifi: remove BT handlers from lib_opsJohannes Berg1-4/+4

2012-03-08iwlwifi: redesign PASSIVE_NO_RX workaroundJohannes Berg1-0/+33
The PASSIVE_NO_RX workaround currently crosses through the op_mode and transport layers, which is a bit odd. This also isn't necessary, if the transport simply reports when queues are full (or no longer full) the op_mode can keep track of this state, and report to mac80211 only what *it* thinks is appropriate. What is appropriate can then be based on whether queues should be stopped to wait for RX or not. This significantly simplifies the transport API, it no longer needs to expose anything to stop a queue, nor to wake "any" queue, this can all be handled in the upper layer completely. Also simplify the handling to not be dependent on the context, that makes little sense as the queues are shared and both contexts have to be on the same channel anyway.

2012-03-07iwlwifi: virtualize command queue full behaviourJohannes Berg1-0/+11
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.

Add wrappers to send commands from the DVM op-mode (which essentially consists of the current driver). This will allow us to move specific sanity checks there.

2012-03-07iwlwifi: remove iwl-wifi.hJohannes Berg1-1/+0
This file was recently introduced, but then directly abused -- it contained private data that shouldn't have been used by anything but the implementation of firmware requests and some very core code. Now that it is no longer accessed by any code but the code in iwl-drv.c, we can dissolve it. Also rename the iwl_nic struct to iwl_drv to better reflect where and how it is used.

2012-03-07iwlwifi: split out firmware storeJohannes Berg1-4/+6
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.

uCode loading belongs to the op_mode, as it is dependent on various things there and the commands sent during it are specific to it. Move the prototypes to iwl-agn.h to indicate this.

There's no reason to set EXIT_PENDING when we start removing the module, as mac80211 will cleanly shut down the device in this case. Additionally, there's no point in rejecting commands to the device when we're cleaning up as that only leads to unwanted errors from mac80211 being printed, such as failed to remove key (...) from hardware (-16) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.
