Kufanele ufake ilabhulali ye-Intel Threading Building Blocks (TBB) njengoba umshayeli we-DMA ethembele kuyo.
Kufanele futhi usethe amakhasi amakhulu amabili we-1 GB ukuze usebenzise i-sampisicelo. $ sudo sh -c “echo 2 > /sys/kernel/mm/hugepages/hugepages-1048576kB/ nr_hugepages”

Yenza lezi zinyathelo ezilandelayo ukulanda i-bitstream ye-DMA Accelerator Function (AF), ukwakha uhlelo lokusebenza nomshayeli, nokusebenzisa i-design ex.ample:

Shintshela kuhlelo lwe-DMA nenkomba yomshayeli: cd $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/sw
Yakha umshayeli kanye nesicelo: yenza

Landa i-bitstream ye-DMA AFU: sudo fpgasupdate ../bin/dma_afu_unsigned.gbs
Sebenzisa uhlelo lokusebenza lokusingatha ukuze ubhale u-100 MB kuzingxenye ezingu-1 MB ukusuka kumemori yokusingatha ukuya kumemori yedivayisi ye-FPGA uphinde uyifunde: ./ fpga_dma_test -s 104857600 -p 1048576 -r mtom

Ukuhlanganisa i-DMA AFU Example

Ukuze ukhiqize indawo yokwakha yokuhlanganisa ukuze uhlanganise i-AF, sebenzisa umyalo othi afu_synth_setup kanje:

Shintsha ku-DMA AFU sample directory: $OPAE_PLATFORM_ROOT/hw/samples/dma_afu
Khiqiza umkhombandlela wokwakha umklamo: afu_synth_setup -source hw/rtl/filelist.txt build_synth

Kusuka kuhla lwemibhalo lokwakha oluhlanganisiwe olukhiqizwe i-afu_synth_setup, faka imiyalo elandelayo efasiteleni letheminali ukuze ukhiqize i-AF yengxenyekazi yezingxenyekazi zekhompuyutha okuqondiwe: cd build_synth run.sh Iskripthi sesizukulwane se-run.sh AF sidala isithombe se-AF ngesisekelo esifanayo. fileigama njengokucushwa kweplathifomu ye-AFU file (.json) nesijobelelo esithi .gbs endaweni:$OPAE_PLATFORM_ROOT/hw/sampLes/build_synth/dma_afu_s10.gbs Intel Corporation. Wonke Amalungelo Agodliwe. I-Intel, ilogo ye-Intel, nezinye izimpawu ze-Intel yizimpawu zokuthengisa ze-Intel Corporation noma izinkampani ezingaphansi kwayo. I-Intel iqinisekisa ukusebenza kwe-FPGA yayo kanye nemikhiqizo ye-semiconductor ekucacisweni kwamanje ngokuvumelana newaranti evamile ye-Intel, kodwa igodla ilungelo lokwenza izinguquko kunoma imiphi imikhiqizo namasevisi nganoma yisiphi isikhathi ngaphandle kwesaziso.

Ukulingisa i-AFU Example

I-Intel incoma ukuthi ubhekisele ku-Intel Accelerator Functional Unit (AFU) Simulation Environment (ASE) Quick Start Guide ukuze i-Intel FPGA PAC yakho ijwayele ukulingisa i-ex efanayo.amples kanye nokusetha indawo yakho. Ngaphambi kokuthi uqhubeke ngezinyathelo ezilandelayo, qinisekisa ukuthi i-OPAE_PLATFORM_ROOT imvelo eguquguqukayo isethwe kuhla lwemibhalo yokufaka ye-OPAE SDK. Qedela izinyathelo ezilandelayo zokusetha isilingisi sehadiwe se-DMA AFU:

Shintsha ku-DMA AFU sample directory: cd $OPAE_PLATFORM_ROOT/hw/samples/dma_afu

Dala indawo ye-ASE kumkhombandlela omusha futhi uyilungiselele ukuze ilingise i-AFU: afu_sim_setup -source hw/rtl/filelist.txt build_ase_dir
Shintshela kumkhombandlela wokwakha we-ASE: cd build_ase_dir
Yakha umshayeli kanye nesicelo: yenza

Yenza ukulingisa: yenza sim

Sampumphumela ovela kusifanisi sehadiwe:

[SIM] ** QAPHELA : NGAPHAMBI kokusebenzisa uhlelo lwesofthiwe ** [SIM] Setha i-env(ASE_WORKDIR) kutheminali lapho uhlelo luzosebenza khona (kopisha bese unamathisela) => [SIM] $SHELL | Gijimani:[SIM] ———+—————————————————— [SIM] bash/zsh | thekelisa ASE_WORKDIR=$OPAE_PLATFORM_ROOT/hw/samples/dma_afu/ase_mkdir/work [SIM] tcsh/csh | setenv ASE_WORKDIR $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/ase_mkdir/work [SIM] Nganoma iyiphi enye i-$SHELL, thintana nomlawuli wakho we-Linux [SIM] [SIM] Isilungele ukulingiswa… [SIM] Cindezela u-CTRL-C ukuze uvale isifanisi...

Qedela lezi zinyathelo ezilandelayo ukuze uhlanganise futhi usebenzise isofthiwe ye-DMA AFU endaweni yokulingisa:

Vula iwindi elisha letheminali.
Shintsha uhla lwemibhalo lube: cd $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/sw

Ukulingisa i-AFU Example

Kopisha iyunithi yezinhlamvu zokusetha imvelo (khetha iyunithi yezinhlamvu efanele igobolondo lakho) kusukela ezinyathelweni ezingenhla ekulingiseni ihadiwe kuya efasiteleni letheminali. Bheka imigqa elandelayo ku-sample okukhiphayo kusuka kusifanisi sehadiwe.

Ukuthuthukisa Ukusebenza Kwe-DMA Okuthuthukisiwe

Ukusetshenziswa kwe-NUMA (ukufinyelela inkumbulo okungajwayelekile) ukwenza ngokugcwele ku-fpga_dma_test.cpp kuvumela iphrosesa ukuthi ifinyelele inkumbulo yayo yendawo ngokushesha kunokufinyelela inkumbulo okungeyona eyendawo (inkumbulo yendawo iye kwenye iphrosesa). Ukucushwa kwe-NUMA okujwayelekile kukhonjisiwe kumdwebo ongezansi. Ukufinyelela kwendawo kumelela ukufinyelela kusuka kungqikithi kuya kumemori yendawo kuya kumongo ofanayo. Ukufinyelela okukude kubonisa indlela ethathwa lapho ingqikithi ku-Node 0 ifinyelela inkumbulo ehlala kumemori yendawo ku-Node 1.

Ukucushwa kwe-NUMA okujwayelekile

Sebenzisa ikhodi elandelayo ukuze usebenzise i-NUMA kuhlelo lwakho lokusebenza lokuhlola:
