iwmc3200wifi: Add new Intel Wireless Multicomm 802.11 driver

Browse source 
This driver supports Intel's full MAC wireless multicomm 802.11 hardware.
Although the hardware is a 802.11agn device, we currently only support
802.11ag, in managed and ad-hoc mode (no AP mode for now).

---help---
This option will enable debug tracing and setting for iwm
You can set the debug level and module through debugfs. By
default all modules are set to the IWL_DL_ERR level.
To see the list of debug modules and levels, see iwm/debug.h
For example, if you want the full MLME debug output:
echo 0xff > /debug/iwm/phyN/debug/mlme
Or, if you want the full debug, for all modules:
echo 0xff > /debug/iwm/phyN/debug/level
echo 0xff > /debug/iwm/phyN/debug/modules

/*
* Hardware Abstraction Layer for iwm.
*
* This file mostly defines an abstraction API for
* sending various commands to the target.
*
* We have 2 types of commands: wifi and non-wifi ones.
*
* - wifi commands:
* They are used for sending LMAC and UMAC commands,
* and thus are the most commonly used ones.
* There are 2 different wifi command types, the regular
* one and the LMAC one. The former is used to send
* UMAC commands (see UMAC_CMD_OPCODE_* from umac.h)
* while the latter is used for sending commands to the
* LMAC. If you look at LMAC commands you'll se that they
* are actually regular iwlwifi target commands encapsulated
* into a special UMAC command called UMAC passthrough.
* This is due to the fact the the host talks exclusively
* to the UMAC and so there needs to be a special UMAC
* command for talking to the LMAC.
* This is how a wifi command is layed out:
* ------------------------
* | iwm_udma_out_wifi_hdr |
* ------------------------
* | SW meta_data (32 bits) |
* ------------------------
* | iwm_dev_cmd_hdr |
* ------------------------
* | payload |
* | .... |
*
* - non-wifi, or general commands:
* Those commands are handled by the device's bootrom,
* and are typically sent when the UMAC and the LMAC
* are not yet available.
* * This is how a non-wifi command is layed out:
* ---------------------------
* | iwm_udma_out_nonwifi_hdr |
* ---------------------------
* | payload |
* | .... |
*
* All the commands start with a UDMA header, which is
* basically a 32 bits field. The 4 LSB there define
* an opcode that allows the target to differentiate
* between wifi (opcode is 0xf) and non-wifi commands
* (opcode is [0..0xe]).
*
* When a command (wifi or non-wifi) is supposed to receive
* an answer, we queue the command buffer. When we do receive
* a command response from the UMAC, we go through the list
* of pending command, and pass both the command and the answer
* to the rx handler. Each command is sent with a unique
* sequence id, and the answer is sent with the same one. This
* is how we're supposed to match an answer with its command.
* See rx.c:iwm_rx_handle_[non]wifi() and iwm_get_pending_[non]wifi()
* for the implementation details.

* To work around the synchronous answer case, we implemented
* our notification mechanism.
* When a code path needs to wait for a command response
* synchronously, it calls notif_handle(), which waits for the
* right notification to show up, and then process it. Before
* starting to wait, it registered as a waiter for this specific
* answer (by toggling a bit in on of the handler_map), so that
* the rx code knows that it needs to send a notification to the
* waiting processes. It does so by calling iwm_notif_send(),
* which adds the notification to the pending notifications list,
* and then wakes the waiting processes up.

* 4) We schedule the tx worker. There is one worker per tx

* a) We check if we have enough Tx credits (see below for a Tx
* credits description) for the frame length. [iwm_tx_worker]
* b) If we do, we aggregate the Tx frame into a UDMA one, by
* concatenating one REPLY_TX command per Tx frame. [iwm_tx_worker]
* c) When we run out of credits, or when we reach the maximum

* frame. [iwm_tx_worker]
*
* When we run out of Tx credits, the skbs are filling the tx queue,
* and eventually we will stop the netdev queue. [iwm_tx_worker]
* The tx queue is emptied as we're getting new tx credits, by
* scheduling the tx_worker. [iwm_tx_credit_inc]

* Since we're on an SDIO or USB bus, we are not sharing memory
* for storing to be transmitted frames. The host needs to push
* them upstream. As a consequence there needs to be a way for
* the target to let us know if it can actually take more TX frames
* or not. This is what Tx credits are for.
*
* For each Tx HW queue, we have a Tx pool, and then we have one
* unique super pool (spool), which is actually a global pool of
* all the UMAC pages.
* For each Tx pool we have a min_pages, a max_pages fields, and a
* alloc_pages fields. The alloc_pages tracks the number of pages
* currently allocated from the tx pool.
* Here are the rules to check if given a tx frame we have enough
* tx credits for it:
* 1) We translate the frame length into a number of UMAC pages.
* Let's call them n_pages.
* 2) For the corresponding tx pool, we check if n_pages +
* pool->alloc_pages is higher than pool->min_pages. min_pages
* represent a set of pre-allocated pages on the tx pool. If
* that's the case, then we need to allocate those pages from
* the spool. We can do so until we reach spool->max_pages.
* 3) Each tx pool is not allowed to allocate more than pool->max_pages
* from the spool, so once we're over min_pages, we can allocate
* pages from the spool, but not more than max_pages.
*
* When the tx code path needs to send a tx frame, it checks first
* if it has enough tx credits, following those rules. [iwm_tx_credit_get]
* If it does, it then updates the pool and spool counters and
* then send the frame. [iwm_tx_credit_alloc and iwm_tx_credit_dec]
* On the other side, when the UMAC is done transmitting frames, it
* will send a credit update notification to the host. This is when
* the pool and spool counters gets to be decreased. [iwm_tx_credit_inc,
* called from rx.c:iwm_ntf_tx_credit_update]
