2018-03-30liquidio: prevent rx queues from getting stalledRaghu Vatsavayi1-10/+15
This commit has fix for RX traffic issues when we stress test the driver with continuous ifconfig up/down under very high traffic conditions. Reason for the issue is that, in existing liquidio_stop function NAPI is disabled even before actual FW/HW interface is brought down via send_rx_ctrl_cmd(lio, 0). Between time frame of NAPI disable and actual interface down in firmware, firmware continuously enqueues rx traffic to host. When interrupt happens for new packets, host irq handler fails in scheduling NAPI as the NAPI is already disabled. After "ifconfig <iface> up", Host re-enables NAPI but cannot schedule it until it receives another Rx interrupt. Host never receives Rx interrupt as it never cleared the Rx interrupt it received during interface down operation. NIC Rx interrupt gets cleared only when Host processes queue and clears the queue counts. Above anomaly leads to other issues like packet overflow in FW/HW queues, backpressure. Fix: This commit fixes this issue by disabling NAPI only after informing firmware to stop queueing packets to host via send_rx_ctrl_cmd(lio, 0). send_rx_ctrl_cmd is not visible in the patch as it is already there in the code. The DOWN command also waits for any pending packets to be processed by NAPI so that the deadlock will not occur.

2018-03-27liquidio: Removed duplicate Tx queue status checkIntiyaz Basha1-28/+0
Napi is checking Tx queue status and waking the Tx queue if required. Same operation is being done while freeing every Tx buffer. So removed the duplicate operation of checking Tx queue status from the Tx buffer free functions.

Deprecate the 1-bit flag (bit 2 in the SLI_SCRATCH_1 Octeon register) that indicates that the liquidio watchdog kernel thread is running for this NIC. Reason is: it is incompatible with the firmware's use for SLI_SCRATCH_1. In lieu of checking that now-deprecated flag, check the value of oct_dev->adapter_refcount to determine whether or not to create the watchdog kernel thread.

2017-10-22Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller1-1/+1
There were quite a few overlapping sets of changes here. Daniel's bug fix for off-by-ones in the new BPF branch instructions, along with the added allowances for "data_end > ptr + x" forms collided with the metadata additions. Along with those three changes came veritifer test cases, which in their final form I tried to group together properly. If I had just trimmed GIT's conflict tags as-is, this would have split up the meta tests unnecessarily. In the socketmap code, a set of preemption disabling changes overlapped with the rename of bpf_compute_data_end() to bpf_compute_data_pointers(). Changes were made to the mv88e6060.c driver set addr method which got removed in net-next. The hyperv transport socket layer had a locking change in 'net' which overlapped with a change of socket state macro usage in 'net-next'. Signed-off-by: David S. Miller <davem@davemloft.net>

While experimenting with changes to the timekeeping code, I ran into a build error in the liquidio driver: drivers/net/ethernet/cavium/liquidio/lio_main.c: In function 'liquidio_ptp_settime': drivers/net/ethernet/cavium/liquidio/lio_main.c:1850:22: error: passing argument 1 of 'timespec_to_ns' from incompatible pointer type [-Werror=incompatible-pointer-types] The driver had a type mismatch since it was first merged, but this never caused problems because it is only built on 64-bit architectures that define timespec and timespec64 to the same type. If we ever want to compile-test the driver on 32-bit or change the way that 64-bit timespec64 is defined, we need to fix it, so let's just do it now.

2017-08-23liquidio: change manner of detecting whether or not NIC firmware is loadedFelix Manlunas1-6/+0
In the NIC firmware, the 1-bit flag indicating "firmware is loaded" moved from SLI_SCRATCH_1 to SLI_SCRATCH_2 (these are Octeon general-purpose scratch registers). Make the PF driver conform to this change. Remove code that sets the "firmware is loaded" flag because it's now the firmware's job to do that. In the code that detects whether or not the firmware is loaded, don't just rely on checking the "firmware is loaded" flag because that may cause a rare false negative. Add code that deduces whether or not the firmware is loaded; that will never give a false negative. Also bump up driver version to match newer NIC firmware.
