+/*
+ * 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.

+ * Since we're on an SDIO or USB bus, we are not sharing memory

+ * 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]

+ * The size of each of the two buffers is large enough to hold the longest

+ * The RX path goes like that:
+ * 1) The target generates an interrupt each time a new packet is received.
+ * There are 2 RX interrupts, one for each buffer.
+ * 2) The host reads the received packet from one of the double buffers.
+ * 3) The host triggers a target interrupt.

+ *
+ * TX PATH
+ *
+ * The Tx path uses a double buffer and a tx_control structure, each located
+ * at a fixed address in the device's memory. On startup, the host retrieves
+ * the pointers to these addresses. A double buffer allows for continuous data
+ * flow towards the device. The host keeps track of which buffer is available
+ * and alternates between these two buffers on a per packet basis.
+ *
+ * The size of each of the two buffers is large enough to hold the longest
+ * 802.3 packet - maximum size Ethernet packet + header + descriptor.
+ * TX complete indication will be received a-synchronously in a TX done cyclic
+ * buffer which is composed of 16 tx_result descriptors structures and is used
+ * in a cyclic manner.
+ *
+ * The TX (HOST) procedure is as follows:
+ * 1. Read the Tx path status, that will give the data_out_count.
+ * 2. goto 1, if not possible.
+ * i.e. if data_in_count - data_out_count >= HwBuffer size (2 for double
+ * buffer).
+ * 3. Copy the packet (preceded by double_buffer_desc), if possible.
+ * i.e. if data_in_count - data_out_count < HwBuffer size (2 for double
+ * buffer).
+ * 4. increment data_in_count.
+ * 5. Inform the firmware by generating a firmware internal interrupt.
+ * 6. FW will increment data_out_count after it reads the buffer.
+ *
+ * The TX Complete procedure:
+ * 1. To get a TX complete indication the host enables the tx_complete flag in
+ * the TX descriptor Structure.
+ * 2. For each packet with a Tx Complete field set, the firmware adds the
+ * transmit results to the cyclic buffer (txDoneRing) and sets both done_1
+ * and done_2 to 1 to indicate driver ownership.
+ * 3. The firmware sends a Tx Complete interrupt to the host to trigger the
+ * host to process the new data. Note: interrupt will be send per packet if
+ * TX complete indication was requested in tx_control or per crossing
+ * aggregation threshold.
+ * 4. After receiving the Tx Complete interrupt, the host reads the
+ * TxDescriptorDone information in a cyclic manner and clears both done_1
+ * and done_2 fields.
