2014-04-07Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Bjorn Van Tilt contributes a patch which fixes a memory leak in usb_8dev's usb_8dev_start_xmit()s error path. A patch by Robert Schwebel fixes a typo in the can documentation. The remaining patches all target the c_can driver. Two of them are by me; they add a missing netif_napi_del() and return value checking. Thomas Gleixner contributes 12 patches, which address several shortcomings in the driver like hardware initialisation, concurrency, message ordering and poor performance. ==================== Signed-off-by: David S.

The function loads the message object from the hardware to get the payload length. The previous patch stores that information in an array, so we can avoid the hardware access. Remove the hardware access and move the led toggle outside of the spinlocked region. Toggle the led only once when at least one packet has been received.

2014-04-01can: c_can: Reduce register accessThomas Gleixner
commit 4ce78a838c (can: c_can: Speed up rx_poll function) hyped a performance improvement by reducing the access to the interrupt pending register from a dual 16 bit to a single 16 bit access. Wow! Thereby it crippled the driver to cast the 16 msg objects in stone, which is completly braindead as contemporary hardware has up to 128 message objects. Supporting larger object buffers is a major surgery, but it'd be definitely worth it especially as the driver does not support HW message filtering .... The logic of the "FIFO" implementation is to split the FIFO in half. For the lower half we read the buffers and clear the interrupt pending bit, but keep the newdat bit set, so the HW will queue above those buffers. When we read out the last low buffer then we reenable all the low half buffers by clearing the newdat bit. The upper half buffers clear the newdat and the interrupt pending bit right away as we know that the lower half bits are clear and give us a headstart against the hardware. Now the implementation is: transfer_message_object() read_object_and_put_into_skb(); if (obj < END_OF_LOW_BUF) clear_intpending(obj) else if (obj > END_OF_LOW_BUF) clear_intpending_and_newdat(obj) else if (obj == END_OF_LOW_BUF) clear_newdat_of_all_low_objects() The hardware allows to avoid most of the mess simply because we can tell the transfer_message_object() function to clear bits right away. So we can be clever and do: if (obj <= END_OF_LOW_BUF) ctrl = TRANSFER_MSG | CLEAR_INTPND; else ctrl = TRANSFER_MSG | CLEAR_INTPND | CLEAR_NEWDAT; transfer_message_object(ctrl) read_object_and_put_into_skb(); if (obj == END_OF_LOW_BUF) clear_newdat_of_all_low_objects() So we save a complete control operation on all message objects except the one which is the end of the low buffer. That's a few micro seconds per object. I'm not adding a boasting profile to that, simply because it's self explaining.

2014-04-01can: c_can: Remove EOB exitThomas Gleixner
The rx_poll code has the following gem: if (msg_ctrl_save & IF_MCONT_EOB) return num_rx_pkts; The EOB bit is the indicator for the hardware that this is the last configured FIFO object. But this object can contain valid data, if we manage to free up objects before the overrun case hits. Now if the code exits due to the EOB bit set, then this buffer is stale and the interrupt bit and NewDat bit of the buffer are still set. Results in a nice interrupt storm unless we come into an overrun situation where the MSGLST bit gets set. ksoftirqd/0-3 [000] ..s. 79.124101: c_can_poll: rx_poll: val: 00008001 pend 00008001 ksoftirqd/0-3 [000] ..s. 79.124176: c_can_poll: rx_poll: val: 00008000 pend 00008000 ksoftirqd/0-3 [000] ..s. 79.124187: c_can_poll: rx_poll: val: 00008002 pend 00008002 ksoftirqd/0-3 [000] ..s. 79.124256: c_can_poll: rx_poll: val: 00008000 pend 00008000 ksoftirqd/0-3 [000] ..s. 79.124267: c_can_poll: rx_poll: val: 00008000 pend 00008000 The amazing thing is that the check of the MSGLST (aka overrun bit) used to be after the check of the EOB bit. That was "fixed" in commit 5d0f801a2c(can: c_can: Fix RX message handling, handle lost message before EOB). But the author of this "fix" did not even understand that the EOB check is broken as well.

2014-04-01can: c_can: Fix the lost message handlingThomas Gleixner
The lost message handling is broken in several ways. 1) Clearing the message lost flag is done by writing 0 to the message control register of the object. #define IF_MCONT_CLR_MSGLST (0 << 14) That clears the object buffer configuration in the worst case, which results in a loss of the EOB flag. That leaves the FIFO chain without a limit and causes a complete lockup of the HW 2) In case that the error skb allocation fails, the code happily claims that it handed down a packet. Just an accounting bug, but .... 3) The code adds a lot of pointless overhead to that error case, where we need to get stuff done as fast as possible to avoid more packet loss. - printk an annoying error message - reread the object buffer for nothing Fix is simple again: - Use the already known MSGCTRL content and only clear the MSGLST bit - Fix the buffer accounting by adding a proper return code - Remove the pointless operations Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
2014-04-01can: c_can: Fix buffer orderingThomas Gleixner
The buffer handling of c_can has been broken forever. That leads to message reordering: ksoftirqd/0-3 [000] ..s. 79.123776: c_can_poll: rx_poll: val: 00007fff ksoftirqd/0-3 [000] ..s. 79.124101: c_can_poll: rx_poll: val: 00008001 What happens is: CPU HW queue new packet into obj 16 (0-15 are busy) read obj 1-15 return because pending is 0 set pending obj 16 -> pending reg 8000 queue new packet into obj 1 set pending obj 1 -> pending reg 8001 So the current algorithmus reads the newest message first, which violates the ordering rules of CAN. Add proper handling of that situation by analyzing the contents of the pending register for gaps. This does NOT fix the message object corruption which can lead to interrupt storms.

2014-04-01can: c_can: Make it SMP safeThomas Gleixner
The hardware has two message control interfaces, but the code only uses the first one. So on SMP the following can be observed: CPU0 CPU1 rx_poll() write IF1 xmit() write IF1 write IF1 That results in corrupted message object configurations. The TX/RX is not globally serialized it's only serialized on a core. Simple solution: Let RX use IF1 and TX use IF2 and all is good.

2014-04-01can: c_can: Fix hardware raminit functionThomas Gleixner
The function is broken in several ways: - The function does not wait for the init to complete. That can take quite some microseconds. - No protection against being called for two chips at the same time. SMP is such a new thing, right? Clear the start and the init done bit unconditionally and wait for both bits to be clear. In the enable path set the init bit and wait for the init done bit. Add proper locking.

2014-03-17can: populate netdev::dev_id for udev discriminationChristopher R. Baker
My objective is to be able to totally discriminate CAN ports on multi-port cards via udev so as to rename them to semantically interesting/unique names for my system (e.g., "ecuCAN" and "auxCAN" instead of "can0" and "can1"). The following patch assigns the dev_id field to match the channel number on all multi-channel devices. I can only test my two-port Peak PCI card, but it works as expected: ATTRS{dev_id} now expresses the port number and my udev rules now unambiguously pick out and rename my individual CAN ports.

CAN interfaces only support MTU values of 16 (CAN 2.0) and 72 (CAN FD). Setting the MTU to other values is pointless but it does not really hurt. With the introduction of the CAN FD support in drivers/net/can a new function to switch the MTU for CAN FD has been introduced.
