From 8116f3cf4a2a5a4fa2335e6f32023ac50506698f Mon Sep 17 00:00:00 2001 From: Sivakumar Subramani Date: Mon, 17 Sep 2007 13:05:35 -0700 Subject: [S2IO]: Handle and monitor all of the device errors and alarms - Added support to poll entire set of device errors and alarams. - A note on how device errors and alarms are handled: - The adapter will automatically recover from uncorrectable ECC errors. Packets containing corrupted data will be dropped (not transmitted) or tagged as invalid before being passed to the host. - The adapter cannot recover from any internal state machine errors. A state machine error requires a device reset. - Any internal error that could potentially result in .store trampling. (undesirable PCI behaviour)is tagged as a "serious error". In such cases the adapter will give up its ability to be a bus master. In this situation the host will still be able to read internal device registers in order to generate an error report. A device reset is necessary to return to normal operation. - In the event of a pcix data parity error, the adapter will automatically disable itself. Adapter_En will automatically transition from '1' to '0' and the adapter will enter its clean-up routine. Once the device has achieved quiescence, an adapter reset should be performed. - Replaced alarm_intr_handler() with s2io_handle_errors(). - Added statistic counters to monitor the alarms. [ Fix warnings wrt. do_s2io_chk_alarm_bit(), Callers pass in an "unsigned long long *" but the function takes a "u64 *" which is different on many 64-bit platforms. -DaveM ] Signed-off-by: Sivakumar Subramani Signed-off-by: Santosh Rastapur Signed-off-by: Ramkrishna Vepa Signed-off-by: Jeff Garzik --- drivers/net/s2io.h | 24 ++++++++++++++++++++++-- 1 file changed, 22 insertions(+), 2 deletions(-) (limited to 'drivers/net/s2io.h') diff --git a/drivers/net/s2io.h b/drivers/net/s2io.h index b9654dfeb877..1e2e72d6aad2 100644 --- a/drivers/net/s2io.h +++ b/drivers/net/s2io.h @@ -91,7 +91,7 @@ struct swStat { unsigned long long serious_err_cnt; unsigned long long soft_reset_cnt; unsigned long long fifo_full_cnt; - unsigned long long ring_full_cnt; + unsigned long long ring_full_cnt[8]; /* LRO statistics */ unsigned long long clubbed_frms_cnt; unsigned long long sending_both; @@ -126,6 +126,26 @@ struct swStat { unsigned long long rx_buf_size_err_cnt; unsigned long long rx_rxd_corrupt_cnt; unsigned long long rx_unkn_err_cnt; + + /* Error/alarm statistics*/ + unsigned long long tda_err_cnt; + unsigned long long pfc_err_cnt; + unsigned long long pcc_err_cnt; + unsigned long long tti_err_cnt; + unsigned long long lso_err_cnt; + unsigned long long tpa_err_cnt; + unsigned long long sm_err_cnt; + unsigned long long mac_tmac_err_cnt; + unsigned long long mac_rmac_err_cnt; + unsigned long long xgxs_txgxs_err_cnt; + unsigned long long xgxs_rxgxs_err_cnt; + unsigned long long rc_err_cnt; + unsigned long long prc_pcix_err_cnt; + unsigned long long rpa_err_cnt; + unsigned long long rda_err_cnt; + unsigned long long rti_err_cnt; + unsigned long long mc_err_cnt; + }; /* Xpak releated alarm and warnings */ @@ -1018,7 +1038,7 @@ static void free_shared_mem(struct s2io_nic *sp); static int init_nic(struct s2io_nic *nic); static void rx_intr_handler(struct ring_info *ring_data); static void tx_intr_handler(struct fifo_info *fifo_data); -static void alarm_intr_handler(struct s2io_nic *sp); +static void s2io_handle_errors(void * dev_id); static int s2io_starter(void); static void s2io_closer(void); -- cgit v1.2.3
