Hi,
We are working to support the J1939 protocol, using your works on
socketCAN, in AGL (Automotive Grade Linux). We are facing some problems
or questions about how to use it. We still have support for LTSI Kernel
which is 4.14 by now and certainly will be 4.19 for the next and your
work are based on the latest Linux v5.1 version.
Backporting them to 4.19 seems easy, we just took the diff at the head
of the "j1939" branch of linux-can-next repository as patches and
applied them to the mainline 4.19 Kernel. We did the same about the 4.14
but only took the J1939 relative patches with a slight change on
drivers/net/can/dev.c patches in the patches implementing the CAN
midlayer private.
Is it planned to support the 4.19 version in the future as it seems to
be the next LTSI version ? And less probable, do you planned for 4.14
the actual LTSI ?
What do you think about the way we did to backport the work on J1939 ?
Runtime tests aren't been ran for now but we just prove that patches
apply, which is not enough for sure, but as the work are limited to the
J1939 module then we are relatively confident and would appreciate your
feedback.
Best regards
