[rdma-next,0/9] RDMA/bnxt_re: Driver Debug Enhancements

Message

Selvin Xavier Feb. 20, 2025, 6:34 p.m. UTC

For debugging issues in the field, we need to track some of
the resources destroyed in the past. This is primarily required
for tracking certain QPs that encountered errors, leading to
application exits. A framework has been implemented to
save this information and retrieve it during coredump collection.

The Broadcom bnxt L2 driver supports collecting driver dumps
using the ethtool -w option. This feature now also supports
collecting coredump information from the bnxt_re auxiliary driver.
Two new callbacks have been implemented to exchange dump
information supported by the auxbus bnxt_re driver.

The bnxt_re driver caches certain hardware information before
resources are destroyed in the HW. Additionally,
some resource information from the host is necessary
for gathering meaningful debug information. Both types
of information are cached by the driver for a finite (1024 for now)
 number of resources. 

Please review and apply.

Thanks,
Selvin Xavier
