Subject: [PATCH v2 0/3] e1000e,igb,ixgbe: add registers etc. printout code just before resetting adapters
Date: Fri, 22 Jan 2010 14:45:24 +0900 [thread overview]
Message-ID: <4B593B74.2020601@jp.fujitsu.com> (raw)
Hi Jeff,
This patchset is the update version of "register etc. printout code" patch. (sorry
for late reply)
The old one is http://marc.info/?l=linux-netdev&m=126286127208276&w=2
v1 -> v2:
- replaced hexdump() with print_hex_dump()
- changed the register printout inplementation (for-switch-case -> data-driven-table)
However the default value of "dump_flag" is not changed (still 1).
The reason I didn't change is
- I think HW index (TDH,TDT..) and SW index (NTC,NTU) are at least necessary
- the amount of default output is not so large (see bellow)
- the adapter resetting problem doesn't happen frequently
The default output sample (NOT the actual hangup case) is as follows:
