git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2020-11-20 The first patch is by Yegor Yefremov and he improves the j1939 documentaton by adding tables for the CAN identifier and its fields. Then there are 8 patches by Oliver Hartkopp targeting the CAN driver infrastructure and drivers. These add support for optional DLC element to the Classical CAN frame structure. See patch ea7800565a12 ("can: add optional DLC element to Classical CAN frame structure") for details. Oliver's last patch adds len8_dlc support to several drivers. Stefan Mätje provides a patch to add len8_dlc support to the esd_usb2 driver. The next patch is by Oliver Hartkopp, too and adds support for modification of Classical CAN DLCs to CAN GW sockets. The next 3 patches target the nxp,flexcan DT bindings. One patch by my adds the missing uint32 reference to the clock-frequency property. Joakim Zhang's patches fix the fsl,clk-source property and add the IMX_SC_R_CAN() macro to the imx firmware header file, which will be used in the flexcan driver later. Another patch by Joakim Zhang prepares the flexcan driver for SCU based stop-mode, by giving the existing, GPR based stop-mode, a _GPR postfix. The next 5 patches are by me, target the flexcan driver, and clean up the .ndo_open and .ndo_stop callbacks. These patches try to fix a sporadically hanging flexcan_close() during simultanious ifdown, sending of CAN messages and probably open CAN bus. I was never able to reproduce, but these seem to fix the problem at the reporting user. As these changes are rather big, I'd like to mainline them via net-next/master. The next patches are by Jimmy Assarsson and Christer Beskow, they add support for new USB devices to the existing kvaser_usb driver. The last patch is by Kaixu Xia and simplifies the return in the mcp251xfd_chip_softreset() function in the mcp251xfd driver. * tag 'linux-can-next-for-5.11-20201120' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next: (25 commits) can: mcp251xfd: remove useless code in mcp251xfd_chip_softreset can: kvaser_usb: Add new Kvaser hydra devices can: kvaser_usb: kvaser_usb_hydra: Add support for new device variant can: kvaser_usb: Add new Kvaser Leaf v2 devices can: kvaser_usb: Add USB_{LEAF,HYDRA}_PRODUCT_ID_END defines can: flexcan: flexcan_close(): change order if commands to properly shut down the controller can: flexcan: flexcan_open(): completely initialize controller before requesting IRQ can: flexcan: flexcan_rx_offload_setup(): factor out mailbox and rx-offload setup into separate function can: flexcan: move enabling/disabling of interrupts from flexcan_chip_{start,stop}() to callers can: flexcan: factor out enabling and disabling of interrupts into separate function can: flexcan: rename macro FLEXCAN_QUIRK_SETUP_STOP_MODE -> FLEXCAN_QUIRK_SETUP_STOP_MODE_GPR dt-bindings: firmware: add IMX_SC_R_CAN(x) macro for CAN dt-bindings: can: fsl,flexcan: fix fsl,clk-source property dt-bindings: can: fsl,flexcan: add uint32 reference to clock-frequency property can: gw: support modification of Classical CAN DLCs can: drivers: add len8_dlc support for esd_usb2 CAN adapter can: drivers: add len8_dlc support for various CAN adapters can: drivers: introduce helpers to access Classical CAN DLC values can: update documentation for DLC usage in Classical CAN can: rename CAN FD related can_len2dlc and can_dlc2len helpers ... ==================== Link: https://lore.kernel.org/r/20201120133318.3428231-1-mkl@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-11-21net: hns3: add support for pf querying new interrupt resourcesYufeng Mo
For HNAE3_DEVICE_VERSION_V3, a maximum of 1281 interrupt resources are supported. To utilize these new resources, extend the corresponding field or variable to 16bit type, and remove the restriction of NIC client that only use a maximum of 65 interrupt vectors. In addition, the I/O address of the extended interrupt resources are different, so an extra handler is needed. Currently, the total number of interrupts is the sum of RoCE's number and RoCE's offset (RoCE is in front of NIC), since the number of both NIC and RoCE are same. For readability, rewrite the corresponding field of the command, rename the RoCE's offset field as the number of NIC interrupts, then the total number of interrupts is sum of the number of RoCE and NIC, and replace vport->back with hdev in hclge_init_roce_base_info() for simplifying the code.

Reduce the amount of time spent replenishing RX buffers by only doing so once available buffers has fallen under a certain threshold, in this case half of the total number of buffers, or if the polling loop exits before the packets processed is less than its budget. Non-exhaustion of NAPI budget implies lower incoming packet pressure, allowing the leeway to refill the buffers in preparation for any impending burst. Signed-off-by: Dwip N.

2020-11-20net: ipa: add driver shutdown callbackAlex Elder
A system shutdown can happen at essentially any time, and it's possible that the IPA driver is busy when a shutdown is underway. IPA hardware accesses IMEM and SMEM memory regions using an IOMMU, and at some point during shutdown, needed I/O mappings could become invalid. This could be disastrous for any "in flight" IPA activity. Avoid this by defining a new driver shutdown callback that stops all IPA activity and cleanly shuts down the driver. It merely calls the driver's existing remove callback, reporting the error if it returns one. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-11-20net: ipa: retry modem stop if busyAlex Elder
The IPA driver remove callback, ipa_remove(), calls ipa_modem_stop() if the setup stage of initialization is complete. If a concurrent call to ipa_modem_start() or ipa_modem_stop() has begin but not completed, ipa_modem_stop() can return an error (-EBUSY). The next patch adds a driver shutdown callback, which will simply call ipa_remove(). We really want our shutdown callback to clean things up. So add a single retry to the ipa_modem_stop() call in ipa_remove() after a short (millisecond) delay. This offers no guarantee the shutdown will complete successfully, but we'll at least try a little harder before giving up.

2020-11-20net: ipa: support retries on generic GSI commandsAlex Elder
When stopping an AP RX channel, there can be a transient period while the channel enters STOP_IN_PROC state before reaching the final STOPPED state. In that case we make another attempt to stop the channel. Similarly, when stopping a modem channel (using a GSI generic command issued from the AP), it's possible that multiple attempts will be required before the channel reaches STOPPED state. Add a field to the GSI structure to record an errno representing the result code provided when a generic command completes. If the result learned in gsi_isr_gp_int1() is RETRY, record -EAGAIN in the result code, otherwise record 0 for success, or -EIO for any other result. If we time out nf gsi_generic_command() waiting for the command to complete, return -ETIMEDOUT (as before). Otherwise return the result stashed by gsi_isr_gp_int1(). Add a loop in gsi_modem_channel_halt() to reissue the HALT command if the result code indicates -EAGAIN. Limit this to 10 retries (after the initial attempt).

2020-11-20net: ipa: ignore CHANNEL_NOT_RUNNING errorsAlex Elder
IPA v4.2 has a hardware quirk that requires the AP to allocate GSI channels for the modem to use. It is recommended that these modem channels get stopped (with a HALT generic command) by the AP when its IPA driver gets removed. The AP has no way of knowing the current state of a modem channel. So when the IPA driver issues a HALT command it's possible the channel is not running, and in that case we get an error indication. This error simply means we didn't need to stop the channel, so we can ignore it. This patch adds an explanation for this situation, and arranges for this condition to *not* report an error message.

2020-11-20net: ipa: don't reset an ALLOCATED channelAlex Elder
If the rmnet_ipa0 network device has not been opened at the time we remove or shut down the IPA driver, its underlying TX and RX GSI channels will not have been started, and they will still be in ALLOCATED state. The RESET command on a channel is meant to return a channel to ALLOCATED state after it's been stopped. But if it was never started, its state will still be ALLOCATED, the RESET command is not required. Quietly skip doing the reset without printing an error message if a channel is already in ALLOCATED state when we request it be reset.

2020-11-20net: ipa: print channel/event ring number on errorAlex Elder
When a GSI command is used to change the state of a channel or event ring we check the state before and after the command to ensure it is as expected. If not, we print an error message, but it does not include the channel or event ring id, and it easily can. Add the channel or event ring id to these error messages.

Populate the core clock rate and interconnect average and peak bandwidth data for SDM845 and SC7180 in their configuration data files. At this point we still don't *use* this data. Note that SC7180 actually defines a new core clock rate (100 MHz instead of 75 MHz) and new interconnect bandwidth values.

2020-11-20r8169: reduce number of workaround doorbell ringsHeiner Kallweit
Some chip versions have a hw bug resulting in lost door bell rings. To work around this the doorbell is also rung whenever we still have tx descriptors in flight after having cleaned up tx descriptors. These PCI(e) writes come at a cost, therefore let's reduce the number of extra doorbell rings. If skb is NULL then this means: - last cleaned-up descriptor belongs to a skb with at least one fragment and last fragment isn't marked as sent yet - hw is in progress sending the skb, therefore no extra doorbell ring is needed for this skb - once last fragment is marked as transmitted hw will trigger a tx done interrupt and we come here again (with skb != NULL) and ring the doorbell if needed Therefore skip the workaround doorbell ring if skb is NULL.

Only when the err equals to -ETIMEDOUT it can reach the 'if (err)' statement, so the 'if (err)' and last 'return -ETIMEDOUT' statements are useless. Romove them.

2020-11-20can: flexcan: flexcan_close(): change order if commands to properly shut ↵Marc Kleine-Budde
down the controller There haven been reports, that the flexcan_close() soradically hangs during simultanious ifdown, sending of CAN messages and probably open CAN bus: | (__schedule) from [<808bbd34>] (schedule+0x90/0xb8) | (schedule) from [<808bf274>] (schedule_timeout+0x1f8/0x24c) | (schedule_timeout) from [<8016be44>] (msleep+0x18/0x1c) | (msleep) from [<80746a64>] (napi_disable+0x60/0x70) | (napi_disable) from [<8052fdd0>] (flexcan_close+0x2c/0x140) | (flexcan_close) from [<80744930>] (__dev_close_many+0xb8/0xd8) | (__dev_close_many) from [<8074db9c>] (__dev_change_flags+0xd0/0x1a0) | (__dev_change_flags) from [<8074dc84>] (dev_change_flags+0x18/0x48) | (dev_change_flags) from [<80760c24>] (do_setlink+0x44c/0x7b4) | (do_setlink) from [<80761560>] (rtnl_newlink+0x374/0x68c) I was unable to reproduce the issue, but a cleanup of the flexcan close sequence has probably fixed the problem at the reporting user. This patch changes the sequence in flexcan_close() to: - stop the TX queue - disable the interrupts on the chip level and wait via free_irq() synchronously for the interrupt handler to finish - disable RX offload, which disables synchronously NAPI - disable the flexcan on the chip level - free RX offload - disable the transceiver - close the CAN device - disable the clocks Link: https://lore.kernel.org/r/20201119100917.3013281-6-mkl@pengutronix.de Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
