| * can: gs_usb: Don't use stack memory for USB transfersEthan Zonca2017-03-031-11/+29
| | | | | | | | | | | | | | | | | | | | | | | | Fixes: 05ca5270005c can: gs_usb: add ethtool set_phys_id callback to locate physical device The gs_usb driver is performing USB transfers using buffers allocated on the stack. This causes the driver to not function with vmapped stacks. Instead, allocate memory for the transfer buffers.

* can: flexcan: add support for timestamp based rx-offloadMarc Kleine-Budde2017-02-061-29/+129
| | | | | | | | | | | | The flexcan IP core has 64 mailboxes. For now they are configured for RX as a hardware FIFO. This FIFO has a fixed depth of 6 CAN frames. In some high load scenarios it turns out thas this buffer is too small. In order to have a buffer larger than the 6 frames FIFO, this patch adds support for timestamp based offloading via the generic rx-offload infrastructure.

| | | | | | | | In order to receive RTR frames in the non HW FIFO mode the RSS and EACEN bits of the reg_ctrl2 have to be activated. As this has no side effect in the FIFO mode, we do this unconditionally on cores with the reg_ctrl2. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
* can: flexcan: activate individual RX masking and initialize reg_rximrMarc Kleine-Budde2017-02-061-1/+7
| | | | | | | | | | | | | | | | | Modern flexcan IP cores support two RX modes. One is using the 6 fames deep hardware FIFO, the other is using up to 64 mailboxes (in non FIFO mode). For now only the HW FIFO mode is activated. In order to make use of the RX mailboxes the individual RX masking feature has to be activated, otherwise matching mailboxes are overwritten during the reception process. This however switches on the individual RX masking, which uses reg_rximr registers for masking. This patch activates the individual RX masking feature unconditionally and initializes the mask registers (reg_rximr) with 0x0 == "don't care", which switches off any filtering.

* can: flexcan: make use of rx-offload's irq_offload_fifoMarc Kleine-Budde2017-02-061-112/+52Star
| | | | | | | | | | | This patch converts the flexcan driver to make use of the rx-offload can_rx_offload_irq_offload_fifo() helper function. The idea is to read the CAN frames already in the interrupt context, as the depth of the flexcan HW FIFO is too shallow, resulting in too many missed frames. During a normal NAPI poll the frames are the pushed into the upper layers. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

* can: rx-offload: Add support for timestamp based irq offloadingMarc Kleine-Budde2017-02-061-2/+135
| | | | | | | | | | | | | | Some CAN controllers don't implement a FIFO in hardware, but fill their mailboxes in a particular order (from lowest to highest or highest to lowest). This makes problems to read the frames in the correct order from the hardware, as new frames might be filled into just read (low) mailboxes. This gets worse, when following new frames are received into not read (higher) mailboxes. On the bright side some these CAN controllers put a timestamp on each received CAN frame. This patch adds support to offload CAN frames in interrupt context, order them by timestamp and then transmitted in a NAPI context. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The priv->device pointer for c_can_pci is never set, but it is used without a NULL check in c_can_start().

This might also cause the pm_runtime_*() functions in c_can.c to actually be executed for c_can_pci devices - they are the only other place where priv->device is used, but they all contain a null check.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A timer was used to restart after the bus-off state, leading to a relatively large can_restart() executed in an interrupt context, which in turn sets up pinctrl. When this happens during system boot, there is a high probability of grabbing the pinctrl_list_mutex, which is locked already by the probe() of other device, making the kernel suspect a deadlock condition [1]. To resolve this issue, the restart_timer is replaced by a delayed work.
