2014-09-19IB/qib: Correct reference counting in debugfs qp_statsMike Marciniszyn
This particular reference count is not needed with the rcu protection, and the current code leaks a reference count, causing a hang in qib_qp_destroy().

2013-06-21IB/qib: Add qp_stats debug fileMike Marciniszyn
This adds a seq_file iterator for reporting the QP hash table when the qp_stats file is read. Reviewed-by: Dean Luick <dean.luick@intel.com> Signed-off-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-06-21IB/qib: Add per-context stats interfaceMike Marciniszyn
This patch adds a debugfs stats interface for per kernel contexts packet counts. The code uses the opcode stats count and eliminates the counter in the context.

2013-06-21IB/qib: Convert opcode counters to per-contextMike Marciniszyn
This fix changes the opcode relative counters for receive to per context. Profiling has shown that when mulitple contexts are being used there is a lot of cache activity associated with these counters. The code formerly kept these counters per port, but only provided the interface to read per HCA. This patch converts the read of counters to per HCA and adds the debugfs hooks to be able to read the file as a sequence of opcodes.
