Miller" , Ian Campbell , Eric Dumazet , Jeff Kirsher , Ben Hutchings , Jiri Pirko , Joe Perches , Szymon Janc , Richard Jones , Ayaz Abdulla , David Decotigny To: netdev@vger.kernel.org, linux-kernel@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org 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 ############################################ # Patch Set Summary: David Decotigny (5): forcedeth: expose module parameters in /sys/module forcedeth: implement ndo_get_stats64() API forcedeth: account for dropped RX frames forcedeth: new ethtool stat counter for TX timeouts forcedeth: stats updated with a deferrable timer Mike Ditto (1): forcedeth: Add messages to indicate using MSI or MSI-X Sameer Nanda (1): forcedeth: allow to silence "TX timeout" debug messages david decotigny (1): forcedeth: fix stats on hardware without extended stats support drivers/net/ethernet/nvidia/forcedeth.c | 344 ++++++++++++++++++++++--------- 1 files changed, 246 insertions(+), 98 deletions(-) -- 1.7.3.1
