2014-07-07at86rf230: rework transmit and receive handlingAlexander Aring1-268/+571
This patch is a complete reimplementation of transmit and receive handling for the at86rf230 driver. It solves also six bugs: First: The RX_SAFE_MODE is enabled and the transceiver doesn't leave the receive state while the framebuffer isn't read by a CMD_FB command. This is useful to read out the frame and don't get into another receive or transmit state, otherwise the frame would be overwritten. The current driver do twice CMD_FB calls, the first one leaves this protection. Second: Sometimes the CRC calculation is correct and the length field is greater 127. The current mac802154 layer and filter of a at86rf2xx doesn't check on this and the kernel crashes. In this case the frame is corrupted, we send the whole receive buffer to the next layer which can be useful for sniffing. Thrid: There is a undocumented race condition. When we are go into the RX_AACK_ON state the transceiver could be changed into RX_AACK_BUSY state. This is a normal behaviour. In this case the transceiver received a SHR while assert wasn't finished. Fourth: It also handle some more "correct" state changes. In aret mode the transceiver need to go to TX_ON before the transceiver go into RX_AACK_ON. Fifth: The programming model [0] describes also a error handling in ARET mode if the trac status is different than zero. This is patch adds support for handling this. Sixth: In receive handling the transceiver should also get the trac status according [0]. The driver could use the trac status as error statistic handling, but the driver doesn't use this currently. There is maybe some timing behaviour or the read of this register change some transceiver states. In addition the irqworker is removed. Instead we do async spi calls and no scheduling is involved anymore. The transmit function is also asynchron but with a wait_for_completion handling. The mac802154 layer doesn't support asynchron transmit handling right now. The state change behaviour is now changes, before it was: 1. assert while(!STATE_TRANSITION_IN_PROGRESS) 2. state change 3. assert while(!STATE_TRANSITION_IN_PROGRESS) 4. assert once(wanted state != current state) Sometimes a unexcepted state change occurs when 4. assert was violated. The new state change behaviour is: 1. assert while(!STATE_TRANSITION_IN_PROGRESS) 2. state change 3. wait state change timing according datasheet 4. assert once(wanted state != current state) This behaviour is described in the at86rf231 software programming model [0]. The state change documentation in this programming guide should also valid for at86rf212 and at86rf233 chips. The transceiver don't do a FORCE_TX_ON while we want to transmit a PDU. The new behaviour is a TX_ON and wait a receiving time (tFrame + tPAck). If we are still in RX_AACK_BUSY then we transmit a FORCE_TX_ON as timeout handling. The different is that FORCE_TX_ON aborts receiving and TX_ON waits if RX_AACK_BUSY is finished. This should decrease the drop rate of packets.

Commit 8eba0eefae24953962067 ("at86rf230: remove irq_type in request_irq") removed the trigger configuration when requesting an irq, and instead relied on the interrupt trigger to be properly configured already. This does not seem to be an assumption that can be safely made, since boards disable all interrupt triggers on boot. On these boards, force the irq to trigger on rising edge, which is also the default for the chip. Signed-off-by: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: David S.

This patch fix a unexpected state change for the at86rf231 chip. We can't change into STATE_FORCE_TX_ON while the chip is in one of SLEEP, P_ON, RESET, TRX_OFF, and all *_NOCLK states. In this case we are in the TRX_OFF state. See datasheet [1] page 71 for more information. Without this patch you will get the following message on a at86rf231 device: [ 20.065218] unexpected state change: 8, asked for 4 [ 20.070527] ------------[ cut here ]------------ [ 20.075414] WARNING: CPU: 0 PID: 160 at net/mac802154/ieee802154_dev.c:43 mac802154_slave_open+0x70/0xb8() [ 20.085594] Modules linked in: autofs4 [ 20.089667] CPU: 0 PID: 160 Comm: ifconfig Not tainted 3.14.0-20140108-1-00993-g905c192 #162 [ 20.098612] [<c00127b8>] (unwind_backtrace) from [<c0010b1c>] (show_stack+0x10/0x14) [ 20.106819] [<c0010b1c>] (show_stack) from [<c0033838>] (warn_slowpath_common+0x60/0x80) [ 20.115311] [<c0033838>] (warn_slowpath_common) from [<c00338e8>] (warn_slowpath_null+0x18/0x20) [ 20.124590] [<c00338e8>] (warn_slowpath_null) from [<c057b7e8>] (mac802154_slave_open+0x70/0xb8) [ 20.133880] [<c057b7e8>] (mac802154_slave_open) from [<c0488a58>] (__dev_open+0xa8/0x108) [ 20.142553] [<c0488a58>] (__dev_open) from [<c0488cb0>] (__dev_change_flags+0x8c/0x148) [ 20.151051] [<c0488cb0>] (__dev_change_flags) from [<c0488d84>] (dev_change_flags+0x18/0x48) [ 20.159968] [<c0488d84>] (dev_change_flags) from [<c04e2e9c>] (devinet_ioctl+0x2b0/0x63c) [ 20.168623] [<c04e2e9c>] (devinet_ioctl) from [<c04712e4>] (sock_ioctl+0x23c/0x29c) [ 20.176727] [<c04712e4>] (sock_ioctl) from [<c00e3cb8>] (do_vfs_ioctl+0x4a8/0x578) [ 20.184671] [<c00e3cb8>] (do_vfs_ioctl) from [<c00e3dd4>] (SyS_ioctl+0x4c/0x78) [ 20.192402] [<c00e3dd4>] (SyS_ioctl) from [<c000da00>] (ret_fast_syscall+0x0/0x48) [ 20.200392] ---[ end trace 9a34542f4ea08e47 ]--- This patch was tested on at86rf231 and at86rf212.

2014-03-14ieee802154: enforce consistent endianness in the 802.15.4 stackPhoebe Buckheister3-27/+29
Enable sparse warnings about endianness, replace the remaining fields regarding network operations without explicit endianness annotations with such that are annotated, and propagate this through the entire stack. Uses of ieee802154_addr_sa are not changed yet, this patch is only concerned with all other fields (such as address filters, operation parameters and the likes).

2014-03-14ieee802154: rename struct ieee802154_addr to *_saPhoebe Buckheister1-7/+7
The struct as currently defined uses host byte order for some fields, and most big endian/EUI display byte order for other fields. Inside the stack, endianness should ideally match network byte order where possible to minimize the number of byteswaps done in critical paths, but this patch does not address this; it is only preparatory.

2014-03-12ieee802154: at86rf230: add support for rf233 chipThomas Stilwell2-2/+7
The rf233 and rf231 are sufficiently similar that we can treat rf233 like rf231. rf233 is missing some features that rf231 has, but we don't currently make use of them so there's nothing to handle differently yet. Should we add support in the future for rf231 *_NOCLK or SLEEP states, or PAD_IO drive strength, exceptions will need to be made for rf233.
