Daniel Machon says: ==================== net: microchip: add FDMA library and use it for Sparx5 This patch series is the first of a 2-part series, that adds a new common FDMA library for Microchip switch chips Sparx5 and lan966x. These chips share the same FDMA engine, and as such will benefit from a common library with a common implementation. This also has the benefit of removing a lot open-coded bookkeeping and duplicate code for the two drivers. Additionally, upstreaming efforts for a third chip, lan969x, will begin in the near future. This chip will use the new library too. In this first series, the FDMA library is introduced and used by the Sparx5 switch driver. ################### # Example of use: # ################### - Initialize the rx and tx fdma structs with values for: number of DCB's, number of DB's, channel ID, DB size (data buffer size), and total size of the requested memory. Also provide two callbacks: nextptr_cb() and dataptr_cb() for getting the nextptr and dataptr. - Allocate memory using fdma_alloc_phys() or fdma_alloc_coherent(). - Initialize the DCB's with fdma_dcb_init(). - Add new DCB's with fdma_dcb_add(). - Free memory with fdma_free_phys() or fdma_free_coherent(). ##################### # Patch breakdown: # ##################### Patch #1: introduces library and selects it for Sparx5. Patch #2: includes the fdma_api.h header and removes old symbols. Patch #3: replaces old rx and tx variables with equivalent ones from the fdma struct. Only the variables that can be changed without breaking traffic is changed in this patch. Patch #4: uses the library for allocation of rx buffers. This requires quite a bit of refactoring in this single patch. Patch #5: uses the library for adding DCB's in the rx path. Patch #6: uses the library for freeing rx buffers. Patch #7: uses the library helpers in the rx path. Patch #8: uses the library for allocation of tx buffers. This requires quite a bit of refactoring in this single patch. Patch #9: uses the library for adding DCB's in the tx path. Patch #10: uses the library helpers in the tx path. Patch #11: ditches the existing linked list for storing buffer addresses, and instead uses offsets into contiguous memory. Patch #12: modifies existing rx and tx functions to be direction independent. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

These direction specific functions can be ditched in favor of a single function: sparx5_fdma_reload(), which retrieves the channel id from the fdma struct instead. Signed-off-by:

Currently, the driver uses a linked list for storing the tx buffer addresses. This requires a good amount of extra bookkeeping code. Ditch the linked list in favor of tx buffers being in the same contiguous memory space as the DCB's and the DB's. The FDMA library has a helper for this - so use that. The tx buffer addresses are now retrieved as an offset into the FDMA memory space. Signed-off-by:

Use the fdma_dcb_add() function to add DCB's in the tx path. This gets rid of the open-coding of nextptr and dataptr handling and leaves it to the library. Also, make sure the fdma indexes are advanced using: fdma_dcb_advance(), so that the correct nextptr and dataptr offsets are retrieved. Signed-off-by:

Daniel Machon authored
Use the two functions: fdma_alloc_phys() and fdma_dcb_init() for tx buffer allocation and use the new buffers throughout. In order to replace the old buffers with the new ones, we have to do the following refactoring: - use fdma_alloc_phys() and fdma_dcb_init() - replace the variables: tx->dma, tx->first_entry and tx->curr_entry with the equivalents from the FDMA struct. - replace uses of sparx5_db_hw and sparx5_tx_dcb_hw with fdma_db and fdma_dcb. - add sparx5_fdma_tx_dataptr_cb callback for obtaining the dataptr. - Initialize FDMA struct values.

This reverts commit bf4d87f8 because it introduced dev_err_probe() in non-probe path, which is not desired. In general, calling dev_err_probe() after successful probe in case of handling -EPROBE_DEFER error, will set deferred status on the device already probed. This is however not a problem here now, because dev_err_probe() in affected places is used for handling errors from request_firmware(), which does not return -EPROBE_DEFER. Still usage of dev_err_probe() in such case is not correct, because request_firmware() could once return -EPROBE_DEFER.

Matthieu Baerts says: ==================== mptcp: MIB counters for MPJ TX + misc improvements Recently, a few issues have been discovered around the creation of additional subflows. Without these counters, it was difficult to point out the reason why some subflows were not created as expected. In patch 3, all error paths from __mptcp_subflow_connect() are covered, except the one related to the 'fully established mode', because it can only happen with the userspace PM, which will propagate the error to the userspace in this case (ENOTCONN). These new counters are also verified in the MPTCP Join selftest in patch 6. While at it, a few other patches are improving the MPTCP path-manager code ... - Patch 1: 'flush' related helpers are renamed to avoid confusions - Patch 2: directly pass known ID and flags to create a new subflow, i/o getting them later by iterating over all endpoints again ... and the MPJoin selftests: - Patch 4: reduce the number of positional parameters - Patch 5: only one line for the 'join' checks, instead of 3 - Patch 7: more explicit check names, instead of sometimes too cryptic ones: rtx, ptx, ftx, ctx, fclzrx, sum - Patch 8: specify client/server instead of 'invert' for some checks not suggesting one specific direction - Patch 9: mute errors of mptcp_connect when ran in the background - Patch 10: simplify checksum_tests by using a for-loop - Patch 11: remove 'define' re-definitions ==================== Link: https://patch.msgid.link/20240902-net-next-mptcp-mib-mpjtx-misc-v1-0-d3e0f3773b90@kernel.orgSigned-off-by: -

'MPTCP_PM_NAME' is defined in 'linux/mptcp_pm.h', included in 'linux/mptcp.h', no need to re-define it. 'MPTCP_PM_EVENTS' is not defined in 'linux/mptcp.h', but 'MPTCP_PM_EV_GRP_NAME' is, with the same value. We can then use the latter, and drop the other one. Reviewed-by:

The test is supposed to be killed before the end, which will likely cause "Connection reset by peer" errors. It is confusing, especially because in case of real transfer errors, the test will not be marked as failed. But that's OK, there are many other tests checking that. Reviewed-by:

Instead of displaying 'invert' when looking at some events like MP_FAIL, MP_FASTCLOSE, MP_RESET, RM_ADDR, which is a bit vague because they are not traditionnaly sent from one side, the host being checked is now printed. For the ADD_ADDR, only display the host when it is the client sending it, which is more unusual. Also before, the 'invert' message was printed after a few checks, but it was not clear which ones exactly. Reviewed-by:

Before, the check names had to be very short. It is no longer the case now that these checks are printed on a dedicated line. Then, it looks better to have more explicit names. Reviewed-by:

A few new MPJoinSynTx MIB counters have been added in a previous commit. They are being validated here in mptcp_join.sh selftest, each time the number of received MPJ are checked. Most of the time, the number of sent SYN+MPJ is the same as the received ones. But sometimes, there are more, because there are dropped, or there are errors. While at it, the "no MPC reuse with single endpoint" subtest has been modified to force a bind() error. Reviewed-by:

Most tests are checking if the expected number of SYN/SYN+ACK/ACK JOINs have been received, each of them on one line. More Join related tests are going to be checked soon, no need to add 5 new lines per test in case of success, just one is enough. In case of issue, the errors will still be reported like before.

chk_join_nr() currently takes 9 positional parameters, 6 of them are optional. It makes it hard to read: chk_join_nr 1 1 1 1 0 1 1 0 4 Naming these vars helps to make it easier to read: join_csum_ns1=1 join_csum_ns2=0 \ join_fail_nr=1 join_rst_nr=1 join_infi_nr=0 \ join_corrupted_pkts=4 \ chk_join_nr 1 1 1 It will then be easier to add new optional parameters.

Recently, a few issues have been discovered around the creation of additional subflows. Without these counters, it was difficult to point out the reason why some subflows were not created as expected. These counters should have been added earlier, because there is no other simple ways to extract such information from the kernel, and understand why subflows have not been created. While at it, some pr_debug() have been added, just in case the errno needs to be printed. Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/509Reviewed-by:

__mptcp_subflow_connect() is currently called from the path-managers, which have all the required information to create subflows. No need to call the PM again to re-iterate over the list of entries with RCU lock to get more info. Instead, it is possible to pass a mptcp_pm_addr_entry structure, instead of a mptcp_addr_info one. The former contains the ifindex and the flags that are required when creating the new subflow. This is a partial revert of commit ee285257 ("mptcp: drop flags and ifindex arguments"). While at it, the local ID can also be set if it is known and 0, to avoid having to set it in the 'rebuild_header' hook, which will cause a new iteration of the endpoint entries. Reviewed-by:

Rename all the helpers specific to the flushing operations to make it clear that the intention is to flush all created subflows, and remove all announced addresses, not just a specific selection. That way, it is easier to understand why the id_avail_bitmap and local_addr_used are reset at the end. Reviewed-by:

Following Willem's suggestion [1], make it so drivers do not have to handle SOF_TIMESTAMPING_RX_SOFTWARE and SOF_TIMESTAMPING_SOFTWARE, nor setting of the PHC index to -1. All drivers will now report RX software timestamp as supported. The series is limited to 15 patches, I will submit other drivers in subsequent submissions.
