2023-01-13net: dsa: microchip: ptp: add packet transmission timestampingChristian Eggers4-1/+137
This patch adds the routines for transmission of ptp packets. When the ptp pdelay_req packet to be transmitted, it uses the deferred xmit worker to schedule the packets. During irq_setup, interrupt for Sync, Pdelay_req and Pdelay_rsp are enabled. So interrupt is triggered for all three packets. But for p2p1step, we require only time stamp of Pdelay_req packet. Hence to avoid posting of the completion from ISR routine for Sync and Pdelay_resp packets, ts_en flag is introduced. This controls which packets need to processed for timestamp. After the packet is transmitted, ISR is triggered. The time at which packet transmitted is recorded to separate register. This value is reconstructed to absolute time and posted to the user application through socket error queue.

2023-01-13net: dsa: microchip: ptp: add packet reception timestampingChristian Eggers3-0/+68
Rx Timestamping is done through 4 additional bytes in tail tag. Whenever the ptp packet is received, the 4 byte hardware time stamped value is added before 1 byte tail tag. Also, bit 7 in tail tag indicates it as PTP frame. This 4 byte value is extracted from the tail tag and reconstructed to absolute time and assigned to skb hwtstamp. If the packet received in PDelay_Resp, then partial ingress timestamp is subtracted from the correction field. Since user space tools expects to be done in hardware.

2023-01-13net: dsa: microchip: ptp: enable interrupt for timestampingArun Ramadoss5-2/+259
PTP Interrupt mask and status register differ from the global and port interrupt mechanism by two methods. One is that for global/port interrupt enabling we have to clear the bit but for ptp interrupt we have to set the bit. And other is bit12:0 is reserved in ptp interrupt registers. This forced to not use the generic implementation of global/port interrupt method routine. This patch implement the ptp interrupt mechanism to read the timestamp register for sync, pdelay_req and pdelay_resp. Signed-off-by: Arun Ramadoss <[email protected]> Signed-off-by: David S.

2023-01-13net: dsa: microchip: ptp: manipulating absolute time using ptp hw clockChristian Eggers2-1/+62
This patch is used for reconstructing the absolute time from the 32bit hardware time stamping value. The do_aux ioctl is used for reading the ptp hardware clock and store it to global variable. The timestamped value in tail tag during rx and register during tx are 32 bit value (2 bit seconds and 30 bit nanoseconds). The time taken to read entire ptp clock will be time consuming. In order to speed up, the software clock is maintained. This clock time will be added to 32 bit timestamp to get the absolute time stamp.

2023-01-13net: dsa: microchip: ptp: add 4 bytes in tail tag when ptp enabledArun Ramadoss2-2/+34
When the PTP is enabled in hardware bit 6 of PTP_MSG_CONF1 register, the transmit frame needs additional 4 bytes before the tail tag. It is needed for all the transmission packets irrespective of PTP packets or not. The 4-byte timestamp field is 0 for frames other than Pdelay_Resp. For the one-step Pdelay_Resp, the switch needs the receive timestamp of the Pdelay_Req message so that it can put the turnaround time in the correction field. Since PTP has to be enabled for both Transmission and reception timestamping, driver needs to track of the tx and rx setting of the all the user ports in the switch. Two flags hw_tx_en and hw_rx_en are added in ksz_port to track the timestampping setting of each port. When any one of ports has tx or rx timestampping enabled, bit 6 of PTP_MSG_CONF1 is set and it is indicated to tag_ksz.c through tagger bytes. This flag adds 4 additional bytes to the tail tag. When tx and rx timestamping of all the ports are disabled, then 4 bytes are not added.

Make MTU configurable on KSZ87xx and KSZ88xx series of switches. Before this patch, pre-configured behavior was different on different switch series, due to opposite meaning of the same bit: - KSZ87xx: Reg 4, Bit 1 - if 1, max frame size is 1532; if 0 - 1514 - KSZ88xx: Reg 4, Bit 1 - if 1, max frame size is 1514; if 0 - 1532 Since the code was telling "...

Maximum frame length check is enabled in lan937x switch on POR, But it is found to be disabled on driver during port setup operation. Due to this, packets are not dropped when transmitted with greater than configured value. For testing, setup made for lan1->lan2 transmission and configured lan1 interface with a frame length (less than 1500 as mentioned in documentation) and transmitted packets with greater than configured value. Expected no packets at lan2 end, but packets observed at lan2. Based on the documentation, packets should get discarded if the actual packet length doesn't match the frame length configured. Frame length check should be disabled only for cascaded ports due to tailtags. This feature was disabled on ksz9477 series due to ptp issue, which is not in lan937x series. But since lan937x took ksz9477 as base, frame length check disabled here as well. Patch added to remove this portion from port setup so that maximum frame length check will be active for normal ports.

Tested on KSZ8873 and KSZ9477. Fixes: da8cd08520f3 ("net: dsa: microchip: add support for common phylink mac link up") Signed-off-by: Oleksij Rempel <[email protected]> Signed-off-by: David S.
