- Kuguqulelo lwangoku, cwangcisa imo eguquguqukayo ukuya kwi-$OPAE_PLATFORM_ROOT
Kufuneka ufake ithala leencwadi le-Intel Threading Building Blocks (TBB) ekubeni umqhubi we-DMA ethembele kuyo.
Kuya kufuneka kwakhona umise amaphepha amakhulu amabini e-1 GB ukuqhuba i-sample isicelo. $ sudo sh -c "echo 2 > /sys/kernel/mm/hugepages/hugepages-1048576kB/ nr_hugepages"

Yenza la manyathelo alandelayo ukukhuphela i DMA Accelerator Function (AF) bitstream, ukwakha isicelo kunye nomqhubi, kwaye ukuqhuba uyilo ex.ample:

Guqula kwisicelo se-DMA kunye nolawulo lomqhubi: cd $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/sw
Yakha umqhubi kunye nesicelo: yenza

Khuphela i-bitstream ye-DMA AFU: sudo fpgasupdate ../bin/dma_afu_unsigned.gbs
Phumeza usetyenziso lwenginginya ukubhala 100 MB kwi-1 MB izahlulo ukusuka kwimemori yenginginya ukuya kwimemori yesixhobo seFPGA kwaye uyifunde kwakhona: ./ fpga_dma_test -s 104857600 -p 1048576 -r mtom

Ukuqulunqa i-DMA AFU Example

Ukuvelisa imeko-bume yokwakha ye-synthesis ukuqulunqa i-AF, sebenzisa umyalelo we-afu_synth_setup ngolu hlobo lulandelayo:

Tshintshela kwi-DMA AFU sample directory: $OPAE_PLATFORM_ROOT/hw/samples/dma_afu
Yenza uluhlu lolwakhiwo loyilo: afu_synth_setup -source hw/rtl/filelist.txt build_synth

Ukusuka kuluhlu lolwakhiwo lokudityaniswa oluveliswe ngu afu_synth_setup, ngenisa le miyalelo ilandelayo kwi-terminal yefestile ukwenza i-AF yeqonga lehardware ekujoliswe kulo: cd build_synth run.sh Iskripthi sesizukulwana se-run.sh AF sidala umfanekiso we-AF ngesiseko esifanayo. fileigama njengoqwalaselo lweqonga le-AFU file (.json) kunye .gbs isimamva kwindawo:$OPAE_PLATFORM_ROOT/hw/samples/build_synth/dma_afu_s10.gbs Intel Corporation. Onke Amalungelo Agciniwe. I-Intel, ilogo ye-Intel, kunye nezinye iimpawu ze-Intel ziimpawu zorhwebo ze-Intel Corporation okanye iinkampani eziphantsi kwayo.

Ukulinganisa i-AFU Example

I-Intel icebisa ukuba ubhekisele kwi-Intel Accelerator Functional Unit (AFU) Ukulinganisa Imeko-bume (ASE) IsiKhokelo sokuQala esiKhawulezayo seIntel FPGA PAC yakho ukuba siqhelane nokulinganisa okufanayo.amples kunye nokuseta okusingqongileyo kwakho. Phambi kokuba uqhubeke ngala manyathelo alandelayo, qinisekisa ukuba i-OPAE_PLATFORM_ROOT imo eguquguqukayo isetiwe kuluhlu lofakelo lwe-OPAE SDK. Gqibezela la manyathelo alandelayo ukuseta i-hardware simulator ye-DMA AFU:

Tshintshela kwi-DMA AFU sample directory: cd $OPAE_PLATFORM_ROOT/hw/samples/dma_afu

Yenza indawo ye-ASE kulawulo olutsha kwaye uyiqwalasele ukuze ufanise i-AFU: afu_sim_setup -source hw/rtl/filelist.txt build_ase_dir
Tshintshela kuluhlu lokwakha lwe-ASE: cd build_ase_dir
Yakha umqhubi kunye nesicelo: yenza

Yenza ukulinganisa: yenza sim

UPhuculo lokuPhuculwa kokuSebenza kweDMA

Ukuphunyezwa kwe-NUMA (ukufikelela kwimemori engalinganiyo) ukulungiswa kwi-fpga_dma_test.cpp ivumela iprosesa ukuba ifikelele kwimemori yayo yendawo ngokukhawuleza kunokufikelela kwimemori engeyiyo yendawo (imemori yendawo ukuya kwenye iprosesa). Ubume be-NUMA obuqhelekileyo bubonisiwe kulo mzobo ungezantsi. Ufikelelo lwendawo lumele ufikelelo ukusuka kumbindi ukuya kwinkumbulo yendawo ukuya kumbindi ofanayo. Ufikelelo olukude lubonisa indlela ethathiweyo xa undoqo kwiNode 0 ifikelela kwimemori ehlala kwinkumbulo yendawo ukuya kwiNode 1.

Uqwalaselo oluqhelekileyo lwe-NUMA

Sebenzisa le khowudi ilandelayo ukuphumeza usetyenziso lwe-NUMA kwisicelo sakho sovavanyo:

// Misela ubudlelwane obufanelekileyo ukuba uceliwe ukuba (cpu_affinity || memory_affinity) {unsigned dom = 0, ibhasi = 0, dev = 0, func = 0; fpga_properties props;int retval; #ukuba(FPGA_DMA_DEBUG)char str[4096]; #endifres = fpgaGetProperties(afc_token, &props); ON_ERR_GOTO(res, out_destroy_tok, “fpgaGetProperties”); res = fpgaPropertiesGetBus(iipropu, (uint8_t *) & ibhasi); ON_ERR_GOTO(res, out_destroy_tok, “fpgaPropertiesGetBus”); res = fpgappropergericevice (Props, (i-Uint8_T *) & i-DPEAPRERGERGERTECTUTE Ukungasebenzi "); // Fumana isixhobo kwi-topology hwloc_topology_t topology; hwloc_topology_init(&topology); hwloc_topology_set_flags(topology, HWLOC_TOPOLOGY_FLAG_IO_DEVICES);Intel Corporation.
