Subject: [PATCH net-next v4 0/8] forcedeth: stats & debug enhancements
Date: Tue, 15 Nov 2011 11:25:33 -0800 [thread overview]
Message-ID: <cover.1321384662.git.david.decotigny@google.com> (raw)
These changes implement the ndo_get_stats64 API and add a few more
stats and debugging features for forcedeth. They also ensure that
stats updates are correct in SMP systems, 32 or 64-bits.
Changes since v3:
- updated get_stats64 + rx_dropped patches to use u64_stats_sync.h
- dropped indentation "whitespace/indentation fixes" (included in
get_stats64 api patch)
Changes since v2:
- patch 1/9 is the cherry-pick of 898bdf2cb43e ("forcedeth: fix
stats on hardware without extended stats support")
- removed patch 5/10 "stats for rx_packets based on hardware
registers" because packets&bytes stats are updated in software
only (898bdf2cb43e)
Changes since v1:
- patch 1/10 is the same as
http://patchwork.ozlabs.org/patch/125017/ (targetting net)
- other patches updated to take patch 1/10 into account
- various commit message updates
Tested:
~150Mbps incoming TCP, ethtool -S in a loop, x86_64 16-way:
tx_bytes: 5441989419
rx_packets: 5439224
tx_timeout: 0
tx_packets: 5456705
rx_bytes: 5566763850
Tested:
pktgen + loopback report same RX/TX packets and bytes stats
Tested:
tests above with Kconfig DEBUG_PAGEALLOC DEBUG_MUTEXES
DEBUG_SPINLOCK LOCKUP_DETECTOR DEBUG_RT_MUTEXES DEBUG_LOCK_ALLOC
PROVE_LOCKING DEBUG_ATOMIC_SLEEP DEBUG_STACK_USAGE DEBUG_KOBJECT
DEBUG_VM DEBUG_LIST DEBUG_SG DEBUG_NOTIFIERS TEST_KSTRTOX
STRICT_DEVMEM DEBUG_STACKOVERFLOW
