| 11 years 11 months | ieee802154/at86rf230: Add Automatic retransmit form the extended mode This will handle CSMA/CA for us as well as re-sending frames when no ack comes in timely. Signed-off-by: Stefan Schmidt <stefan@datenfreihafen.org> |
| 11 years 11 months | ieee802154/at86rf230.c: Prepare driver for auto ACK support Implement the filter function to update short address, pan id and ieee address on change. Allowing for hardware address filtering needed for auto ACK. Switch state machine to use auto ACK states for rx. Currently wrapped in ugly ifdef's until automatic re-transmit is also in place. Testing for auto ACK showed no problems so far. Signed-off-by: Stefan Schmidt <stefan@datenfreihafen.org> |
| 11 years 11 months | ieee802154/at86rf230.h: Fix register names for RX_AACK_ON and
TX_ARET_ON The register names have been wrong since the beginning but it only showed up now as they are actualy used for the upcoming auto ACK support. Signed-off-by: Stefan Schmidt <stefan@datenfreihafen.org> |
| 12 years 2 months | atusb: use MODULE_AUTHOR according to include/linux/module.h; added
myself include/linux/module.h decrees: /* * Author(s), use "Name <email>" or just "Name", for multiple * authors use multiple MODULE_AUTHOR() statements/lines. */ Make it so. |

Commit 846338826bb4971daa49c454d6c34f366d0f66fe,
by Werner Almesberger

|
| 12 years 2 months | atusb: changed interrupt synchronization from fixed delay to
SPI_WRITE2_SYNC The fixed 10 ms delay was an unnecessary waste of time. The new mechanism synchronized interrupts by matching the interrupt's serial number (sent on EP 1) with the serial returned by the new request ATUSB_SPI_WRITE2_SYNC. If we don't have a match, a 50 ms timeout will kick in. This will save us in situations where EP 1 has a problem or also in case a new interrupt arrives before the ATUSB_SPI_WRITE2_SYNC response.

|
| 12 years 2 months | at86rf230: we may be in BUSY_RX after commanding RX_ON Checking arrival in RX_ON races with incoming traffic. If frame reception begins before we have a chance to see that we've arrived in RX_ON, at86rf230_state complains about unexpectedly finding the transceiver in BUSY_RX. This isn't the prettiest solution (and it doesn't check if we're in BUSY_RX before even commanding the change, although I think this shouldn't happen), but it makes the problem go away.

by Werner Almesberger
|
|
| 12 years 2 months | atusb: implement interrupt synchronization via a 10 ms delay timer Writes to TRX_STATE may have to act as interrupt barriers. Since we currently have no direct means for ensuring that host and atusb are synchronized, we simply wait 10 ms, which should be sufficient to receive any pending bulk data. Moved the TRX_STATE change detection logic from atusb_transfer to atusb_write and implemented the delay via a timer. Signed-off-by: Werner Almesberger <werner@almesberger.net> |

| 12 years 2 months | atusb: correctly print the build date The code assumed the string send by atusb was NUL-terminated, which it isn't. We therefore can only accept one byte less in the buffer and must terminate the string ourselves. Signed-off-by: Werner Almesberger <werner@almesberger.net> |

| 12 years 2 months | atusb: initially disable the interrupt delivery tasklet This prevents is from firing the interrupt before the driver is ready to handle it. We therefore don't need the work-around in at86rf230.c anymore. Signed-off-by: Werner Almesberger <werner@almesberger.net> |

| 12 years 2 months | atusb: converted interrupt delivery to use tasklets Tasklets are a lot cleaner than the atomic operations and weird logic we had before. And the result should also be more correct ;-) Signed-off-by: Werner Almesberger <werner@almesberger.net> |

Commit edb55e1d9917f35ce2ec30afa47ede66fb06273b,
by Werner Almesberger
|
|
| 12 years 2 months | atusb: added tentative interrupt support Added the USB-to-interrupt logic. The approach is basically to have a bulk URB that waits for an incoming interrupt notification and that gets resubmitted whenever the interrupt is acknowledged. We map enable/disable to an atomic count of the masking depth. To do: - convert printks to dev_dbg or remove them - remove bulk URB on driver unload - implement interrupt synchronization (via an 10 ms timer) - don't make atusb_irq_enable call atusb_do_irq directly but start a tasklet instead. Otherwise, we recurse on a spin lock held somewhere in the interrupt handling infrastructure. We send our first interrupt before at86rf230.c is ready to handle it. This causes all further interrupts to be lost. As a work-around, just clear IRQ_STATUS at the end of at86rf230_probe. Signed-off-by: Werner Almesberger <werner@almesberger.net> |

|
| 12 years 2 months | atusb: removed atusb_build from struct atusb_local and streamlined
"static info" We don't need to keep all this information around after initializing. Also, it's nicer to keep everything in small functions than to spread it out over several of them. Note: it compiles but is otherwise untested. |
