Musanapitirire masitepe otsatirawa, onetsetsani kuti OPAE_PLATFORM_ROOT kusintha kwa chilengedwe kwayikidwa ku chikwatu cha OPAE SDK. Malizitsani izi kuti mukhazikitse makina oyeserera a DMA AFU:

Kusintha kwa DMA AFU sample chikwatu: cd $OPAE_PLATFORM_ROOT/hw/samples/dma_afu

Pangani chilengedwe cha ASE mu bukhu latsopano ndikusintha kuti muyesere AFU: afu_sim_setup -source hw/rtl/filelist.txt build_ase_dir
Sinthani ku chikwatu cha ASE: cd build_ase_dir
Pangani dalaivala ndi kugwiritsa ntchito: make

Pangani kayeseleledwe: pangani sim

Sampzotuluka kuchokera ku hardware simulator:

[SIM] ** CHENJEZO : MUSANATALIBE pulojekiti ** [SIM] Khazikitsani env(ASE_WORKDIR) mu terminal pomwe ntchito idzayendetsedwe (kukopa-ndi kumata) => [SIM] $SHELL | Thamangani:[SIM] ———+—————————————————— [SIM] bash/zsh | kutumiza kunja ASE_WORKDIR=$OPAE_PLATFORM_ROOT/hw/samples/dma_afu/ase_mkdir/work [SIM] tcsh/csh | setenv ASE_WORKDIR $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/ase_mkdir/work [SIM] Pa $SHELL ina iliyonse, funsani woyang'anira Linux [SIM] [SIM] Wokonzeka kuyerekeza… [SIM] Dinani CTRL-C kuti mutseke choyesezera…

Malizitsani izi kuti muphatikize ndikugwiritsa ntchito pulogalamu ya DMA AFU pamalo oyerekeza:

Tsegulani zenera latsopano la terminal.
Sinthani chikwatu kukhala: cd $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/sw

Kutsanzira AFU Example

Koperani chingwe chokhazikitsira chilengedwe (sankhani chingwe choyenera pa chipolopolo chanu) kuchokera pamasitepe omwe ali pamwamba pazithunzithunzi za hardware kupita pawindo la terminal. Onani mizere yotsatirayi mu sampzotuluka kuchokera ku hardware simulator. [SIM] bash/zsh | kutumiza kunja ASE_WORKDIR=$OPAE_PLATFORM_ROOT/hw/samples/dma_afu/build_ase_dir/work [SIM] tcsh/csh | setenv ASE_WORKDIR $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/build_ase_dir/work
Lembani mapulogalamu: $panga USE_ASE=1

Gwiritsani ntchito pulogalamu yolembera kuti mulembe 4 KB mu magawo a 1 KB kuchokera pamtima wokumbukira kubwerera ku FPGA kukumbukira chipangizo mumayendedwe obwereza: ./ fpga_dma_test -s 4096 -p 1024 -r mtom

Kukhathamiritsa kwa Kuchita bwino kwa DMA

Kukhazikitsa kwa NUMA (kufikira kukumbukira kosafanana) mu fpga_dma_test.cpp kumalola purosesa kuti azitha kukumbukira kwawo komweko mwachangu kuposa kupeza kukumbukira komwe sikuli komweko (kukumbukira komweko kupita ku purosesa ina). Kusintha kwanthawi zonse kwa NUMA kukuwonetsedwa pazithunzi pansipa. Kufikira kwanuko kumayimira kulowa kuchokera pachimake kupita kumtima komweko kupita pachimake chomwecho. Kufikira kutali kukuwonetsa njira yomwe idatengedwa pomwe maziko pa Node 0 amafikira kukumbukira komwe kumakhala kukumbukira komweko ku Node 1.

Kusintha kwamtundu wa NUMA

Gwiritsani ntchito nambala iyi kuti mugwiritse ntchito kukhathamiritsa kwa NUMA pamayeso anu:

// Khazikitsani kuyanjana koyenera ngati kufunsidwa ngati (cpu_affinity || memory_affinity) {unsigned dom = 0, basi = 0, dev = 0, func = 0; fpga_properties props;int retval; #if(FPGA_DMA_DEBUG)char str[4096]; #endifres = fpgaGetProperties(afc_token, &props); ON_ERR_GOTO(res, out_destroy_tok, “fpgaGetProperties”); res = fpgaPropertiesGetBus(props, (uint8_t *) & bus); ON_ERR_GOTO(res, out_destroy_tok, “fpgaPropertiesGetBus”); res = fpgaPropertiesGetDevice(props, (uint8_t *) & dev); ON_ERR_GOTO(res, out_destroy_tok, “fpgaPropertiesGetDevice”) res = fpgaPropertiesGetFunction(props, (uint8_t *) & func); ON_RES(ERtok_GO) // Pezani chipangizo kuchokera ku topology hwloc_topology_t topology; hwloc_topology_init(&topology); hwloc_topology_set_flags(topology, HWLOC_TOPOLOGY_FLAG_IO_DEVICES); Intel Corporation. Maumwini onse ndi otetezedwa. Intel, logo ya Intel, ndi zizindikiro zina za Intel ndi zizindikiro za Intel Corporation kapena mabungwe ake. Intel imatsimikizira kugwira ntchito kwa FPGA yake ndi zida za semiconductor malinga ndi zomwe zilipo malinga ndi chitsimikizo cha Intel, koma ili ndi ufulu wosintha zinthu zilizonse ndi ntchito nthawi iliyonse popanda kuzindikira. Intel sakhala ndi udindo kapena udindo chifukwa cha kugwiritsa ntchito kapena kugwiritsa ntchito zidziwitso zilizonse, malonda, kapena ntchito zomwe zafotokozedwa pano kupatula monga momwe Intel adavomerezera momveka bwino. Makasitomala a Intel amalangizidwa kuti apeze mtundu waposachedwa kwambiri wamakina a chipangizocho asanadalire zidziwitso zilizonse zosindikizidwa komanso asanayike maoda azinthu kapena ntchito. *Mayina ena ndi mtundu zitha kunenedwa kuti ndi za ena.
