2022-07-21net/cdc_ncm: Enable ZLP for DisplayLink ethernet devicesDominik Czerwik1-1/+24
This improves performance and stability of DL-3xxx/DL-5xxx/DL-6xxx device series. Specifically prevents device from temporary network dropouts when playing video from the web and network traffic going through is high.

In gsi_trans_free(), there's no point in ipa_gsi_trans_release() if a transaction is unused. No used TREs means no IPA layer resources to clean up.

The transaction map is really associated with the transaction pool; move its definition earlier in the gsi_trans_info structure.

We currently put a transaction on the pending list when it has been committed. But until the channel's doorbell rings, these transactions aren't actually "owned" by the hardware yet. Add a new "committed" state (and list), to represent transactions that have been committed but not yet sent to hardware.

2022-07-20net: ipa: initialize ring indexes to 0Alex Elder2-10/+13
When a GSI channel is initially allocated, and after it has been reset, the hardware assumes its ring index is 0. And although we do initialize channels this way, the comments in the IPA code don't really explain this. For event rings, it doesn't matter what value we use initially, so using 0 is just fine. Add some information about the assumptions made by hardware above the definition of the gsi_ring structure in "gsi.h". Zero the index field for all rings (channel and event) when the ring is allocated. As a result, that function initializes all fields in the structure. Stop zeroing the index the top of gsi_channel_program(). Initially we'll use the index value set when the channel ring was allocated. And we'll explicitly zero the index value in gsi_channel_reset() before programming the hardware, adding a comment explaining why it's required. For event rings, use the index initialized by gsi_ring_alloc() rather than 0 when ringing the doorbell in gsi_evt_ring_program(). (It'll still be zero, but we won't assume that to be the case.) Use a local variable in gsi_evt_ring_program() that represents the address of the event ring's ring structure. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

2022-07-19net/mlx5e: Add resiliency for PTP TX port timestampAya Levin5-2/+50
PTP TX port timestamp relies on receiving 2 CQEs for each outgoing packet (WQE). The regular CQE has a less accurate timestamp than the wire CQE. On link change, the wire CQE may get lost. Let the driver detect and restore the relation between the CQEs, and re-sync after timeout. Add resiliency for this as follows: add id (producer counter) into the WQE's metadata. This id will be received in the wire CQE (in wqe_counter field). On handling the wire CQE, if there is no match, replay the PTP application with the time-stamp from the regular CQE and restore the sync between the CQEs and their SKBs. This patch adds 2 ptp counters: 1) ptp_cq0_resync_event: number of times a mismatch was detected between the regular CQE and the wire CQE. 2) ptp_cq0_resync_cqe: total amount of missing wire CQEs.

2022-07-19can: ctucanfd: Update CTU CAN FD IP core registers to match version 3.x.Pavel Pisa1-4/+28
The update is compatible/pure extension of 2.x IP core version - new option for 2, 4, or 8 Tx buffers option during synthesis. The 2.x version has fixed 4 Tx buffers. 3.x version default is 4 as well - new REG_TX_COMMAND_TXT_BUFFER_COUNT provides synthesis choice. When read as 0 assume 2.x core with fixed 4 Tx buffers. - new REG_ERR_CAPT_TS_BITS field to provide most significant active/implemented timestamp bit. For 2.x read as zero, assume value 63 is such case for 64 bit counter. - new REG_MODE_RXBAM bit which controls automatic advance to next word after Rx FIFO register read. Bit is set to 1 by default after the core reset (REG_MODE_RST) and value 1 has to be preserved for the normal ctucanfd Linux driver operation. Even preceding driver version resets core and then modifies only known/required MODE register bits so backward and forward compatibility is ensured. See complete datasheet for time-triggered and other updated capabilities http://canbus.pages.fel.cvut.cz/ctucanfd_ip_core/doc/Datasheet.pdf The fields related to ongoing Ondrej Ille's work on fault tolerant version with parity protected buffers and FIFOs are not included for now. Their inclusion will be considered when design is settled and tested.

2022-07-19can: slcan: do not sleep with a spin lock heldDario Binacchi1-4/+3
We can't call close_candev() with a spin lock held, so release the lock before calling it. After calling close_candev(), we can update the fields of the private `struct can_priv' without having to acquire the lock.
