setup:
iperf3 -s #on lantiq
./run.sh testX #on host
everything_interrupts.log #cat /proc/interrupts (you may change
the SMP
affinity)
running on experimental 1000Hz build, not much change in speedAs illustrated in vanilla.log, the default xrx200 ethernet driver seems to be really slow in lantiq->host traffic (xDSL download). That seems to be (at least) partially caused by making unnecessary linear skbs in the network stack. These patches (and the ICU SMP ones) can increase the lantiq->host UDP speed to an almost twice as big value and effectively increase the speed of TCP in the both ways too. The changes from "[RFC] [PATCH v2] lantiq: net: ethernet driver with fragments" are: I've had to increase the DMA descriptor count as there is now more than one descriptors for one packet. With the original 64 there would be frequent queue stops, which decreased the speed. With 128 now they are not so much frequent (with 192 even less, almost nonexistant). The main problem is in the TX housekeeping task, where the budgeted cycle of descriptor and skb freeing cannot keep up with xmit function. With a simple computation (I hope it is correct :-D ): 1Gbps / (1500*8 bits) = ~83k, the number of packets which needs to be freed (it will be more descriptors) one run cannot free more than budgeted packets (32), so the housekeeping task would had to be called: 83k / 32 => one every 400 microseconds That's probably nearly impossible. With 1000Hz system the tx housekeeping seemed to be called once about every 3 miliseconds. If the housekeeping gets called after longer time the ring buffer will get actually stuck (it is transmitted, but not yet cleaned) and the queue is stopped until next tx housekeeping is called. I've hacked the housekeeping to ignore budget, so whole possible (= completed and not owned by DMA) ring buffer is freed. I've added dma_unmap_single for tx housekeeping and frags mapping fail path. Interestingly the nonpresence in the original driver was OK for the kernel. Additionally I've changed TX DMA interrupts from an end-of-descriptor to end-of-packet events. The DMA patch tries to change some DMA settings, namely DMA_POLL. I don't have a lantiq technical datasheet (it would be appreciated though :-D), but I assume it is how often does the controller check RAM for DMA_OWN flag. On 0x10 (instead of 0x4) it seems to slighty increase the speed (it is probably using less RAM bus bandwidth). BTW it seems CPOLL register is not dependent on channel settings, so it doesn't have to be on for loop (as in patch). The burst size is set to 8 words (which match 32B alignment in the ethernet driver). P.S. the xrx200 network speed on localhost is only up to 500Mbit/s. Petr
