[RDMA for-next V3 0/6] Add MAD stack trace points

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ira Weiny <ira.weiny@xxxxxxxxx>

A while ago I wrote these patches for MAD stack tracing.  At the time I was
proposing to remove the snoop interface.[1]

For this submission I'd like to propose adding the tracing and leave the snoop
interface in.  While I still don't see a need for the snoop interface, I'm no
longer advocating getting rid of it as the functionality of these patches is
different.

In addition I wrote a sample eBPF which shows how one can further filter at the
tracepoints to distill the information being traced.

Changes for V3:
	Rebased on current RDMA for next
	Change license text to SPDX tag
	Change dev_name to string from array
	Reorder fields for more compact ring buffer utilization
	Use a defined roce address type for safer memcpy/memset
	Adjust BPF to new umad format

Changes for v2:
        Update MAINTAINERS as indicated from Doug
	Now CC'ing the Tracing maintainers so they are aware of the additions
