RDMA/cxgb3: Doorbell overflow avoidance and recovery

2010-02-24T18:40:28+00:00

T3 hardware doorbell FIFO overflows can cause application stalls due to lost doorbell ring events. This has been seen when running large NP IMB alltoall MPI jobs. The T3 hardware supports an xon/xoff-type flow control mechanism to help avoid overflowing the HW doorbell FIFO. This patch uses these interrupts to disable RDMA QP doorbell rings when we near an overflow condition, and then turn them back on (and ring all the active QP doorbells) when when the doorbell FIFO empties out. In addition if an doorbell ring is dropped by the hardware, the code will now recover. Design: cxgb3: - enable these DB interrupts - in the interrupt handler, schedule work tasks to call the ULPs event handlers with the new events. - ring all the qset txqs when an overflow is detected. iw_cxgb3: - disable db ringing on all active qps when we get the DB_FULL event - enable db ringing on all active qps and ring all active dbs when we get the DB_EMPTY event - On DB_DROP event: - disable db rings in the event handler - delay-schedule a work task which rings and enables the dbs on all active qps. - in post_send and post_recv logic, don't ring the db if it's disabled.

cxgb3: detect mac link faults.

2009-03-13T18:30:47+00:00

The driver currently ignores the local or remote link faults raised at the mac layer. This patch fixes it. Our mac however only advertizes link events, so wait for the phy to stabilize the link, then enable mac link events interrupts. Signed-off-by: Divy Le Ray Signed-off-by: David S. Miller

cxgb3: disable high freq non-data interrupts

2009-03-13T18:30:45+00:00

Under RX pressure, The HW might generate a high load of interrupts to signal mac fifo or free lists overflow. Disable the interrupts, and poll the relevant status bits to maintain stats. Signed-off-by: Divy Le Ray Signed-off-by: David S. Miller

cxgb3: More flexible support for PHY interrupts.

2008-10-09T00:39:00+00:00

Do not require PHY interrupts to be connected to GPIs in ascending order. Base interrupt availability both on PHYs supporting them and on GPIs being hooked up. Allows boards to specify interrupt GPIs though the PHYs don't use them. Remove spurious PHY interrupts due to clearing T3DBG interrupts before setting their polarity.
