octeontx2-af: Introduce tracepoints for mailbox Added tracepoints in mailbox code so that the mailbox operations like message allocation, sending message and message interrupts are traced. Also the mailbox errors occurred like timeout or wrong responses are traced. These will help in debugging mailbox issues. Here's an example output showing one of the mailbox messages sent by PF to AF and AF responding to it: ~# mount -t tracefs none /sys/kernel/tracing/ ~# echo 1 > /sys/kernel/tracing/events/rvu/enable ~# ifconfig eth0 up ~# cat /sys/kernel/tracing/trace ~# cat /sys/kernel/tracing/trace tracer: nop _-----=> irqs-off / _----=> need-resched | / _---=> hardirq/softirq || / _--=> preempt-depth ||| / delay TASK-PID CPU# |||| TIMESTAMP FUNCTION | | | |||| | | ifconfig-2382 [002] .... 756.161892: otx2_msg_alloc: [0002:02:00.0] msg:(0x400) size:40 ifconfig-2382 [002] ...1 756.161895: otx2_msg_send: [0002:02:00.0] sent 1 msg(s) of size:48 <idle>-0 [000] d.h1 756.161902: otx2_msg_interrupt: [0002:01:00.0] mbox interrupt PF(s) to AF (0x2) kworker/u49:0-1165 [000] .... 756.162049: otx2_msg_process: [0002:01:00.0] msg:(0x400) error:0 kworker/u49:0-1165 [000] ...1 756.162051: otx2_msg_send: [0002:01:00.0] sent 1 msg(s) of size:32 kworker/u49:0-1165 [000] d.h. 756.162056: otx2_msg_interrupt: [0002:02:00.0] mbox interrupt AF to PF (0x1) Signed-off-by: Subbaraya Sundeep <sbhatta@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

octeontx2-af: Introduce tracepoints for mailbox Added tracepoints in mailbox code so that the mailbox operations like message allocation, sending message and message interrupts are traced. Also the mailbox errors occurred like timeout or wrong responses are traced. These will help in debugging mailbox issues. Here's an example output showing one of the mailbox messages sent by PF to AF and AF responding to it: ~# mount -t tracefs none /sys/kernel/tracing/ ~# echo 1 > /sys/kernel/tracing/events/rvu/enable ~# ifconfig eth0 up ~# cat /sys/kernel/tracing/trace ~# cat /sys/kernel/tracing/trace tracer: nop _-----=> irqs-off / _----=> need-resched | / _---=> hardirq/softirq || / _--=> preempt-depth ||| / delay TASK-PID CPU# |||| TIMESTAMP FUNCTION | | | |||| | | ifconfig-2382 [002] .... 756.161892: otx2_msg_alloc: [0002:02:00.0] msg:(0x400) size:40 ifconfig-2382 [002] ...1 756.161895: otx2_msg_send: [0002:02:00.0] sent 1 msg(s) of size:48 <idle>-0 [000] d.h1 756.161902: otx2_msg_interrupt: [0002:01:00.0] mbox interrupt PF(s) to AF (0x2) kworker/u49:0-1165 [000] .... 756.162049: otx2_msg_process: [0002:01:00.0] msg:(0x400) error:0 kworker/u49:0-1165 [000] ...1 756.162051: otx2_msg_send: [0002:01:00.0] sent 1 msg(s) of size:32 kworker/u49:0-1165 [000] d.h. 756.162056: otx2_msg_interrupt: [0002:02:00.0] mbox interrupt AF to PF (0x1) Signed-off-by: Subbaraya Sundeep <sbhatta@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.
