Pib nrog Intel® Distribution rau GDB * ntawm Linux * OS Host
Pib siv Intel® Distribution rau GDB * rau kev debugging daim ntawv thov. Ua raws li cov lus qhia hauv qab no txhawm rau teeb tsa lub debugger rau debug daim ntawv thov nrog cov kernels offloaded rau CPU thiab GPU li.
Intel® Distribution for GDB* yog muaj ua ib feem ntawm Intel® oneAPI Base Toolkit. Yog xav paub ntxiv txog oneAPI toolkits, mus saib hauv nplooj ntawv khoom.
Mus saib lub Tso Lus Ceeb Toom nplooj ntawv rau cov ntaub ntawv hais txog lub peev xwm tseem ceeb, cov yam ntxwv tshiab, thiab cov teeb meem paub.
Koj tuaj yeem siv SYCL * sample code, Array Transform, pib nrog Intel® Distribution rau GDB*. Cov sample tsis tsim qhov yuam kev thiab tsuas yog piav qhia cov yam ntxwv debugger. Cov cai txheej txheem cov ntsiab lus ntawm cov tswv yim array nyob ntawm seb lawv puas los yog khib thiab tsim cov khoom tso tawm. Koj tuaj yeem siv sample mus debug ntawm ob qho tib si CPU lossis GPU, qhia meej cov khoom xaiv los ntawm kev sib cav kab lus. Nco ntsoov tias GPU debugging yuav xav tau ob lub tshuab thiab teeb tsa ntxiv rau kev debugging tej thaj chaw deb.
Yam yuavtsum tau kawm uantej
Yog tias koj tsom mus debug ntawm GPU, nruab qhov tseeb GPU tsav tsheb thiab teeb tsa koj lub cev siv lawv. Xa mus rau Intel® oneAPI Toolkits Installation Guide for Linux* OS. Ua raws li cov lus qhia Nruab Intel GPU Drivers txhawm rau nruab GPU tsav tsheb sib piv koj lub cev.
Tsis tas li ntawd, koj tuaj yeem nruab qhov txuas ntxiv rau Visual Studio Code * rau kev debugging GPU nrog Intel® Distribution rau GDB *. Xa mus rau lub Siv Visual Studio Code nrog Intel® oneAPI Toolkits Guide.
Teem lub GPU Debugger
Txhawm rau teeb tsa GPU debugger, koj yuav tsum muaj lub hauv paus nkag.
Nco tseg Thaum lub sijhawm debugging ntsiav, GPU raug tso tseg thiab cov zis video tsis muaj nyob rau ntawm koj lub hom phiaj lub tshuab. Vim li no, koj tsis tuaj yeem debug GPU los ntawm lub hom phiaj yog tias daim npav GPU ntawm lub kaw lus kuj tseem siv rau cov duab tso tawm. Hauv qhov no, txuas mus rau lub tshuab ntawm ssh.
1. Yog tias koj tsom mus debug ntawm GPU, Linux Kernel uas txhawb GPU debugging yog xav tau.
a. Ua raws li cov lus qhia ntawm Intel® software rau lub hom phiaj dav dav GPU muaj peev xwm mus download tau thiab nruab cov tsav tsheb tsim nyog.
b. Pab kom i915 debug kev txhawb nqa hauv Kernel:
a. Qhib lub davhlau ya nyob twg.
b. Qhib lub grub file hauv /etc/default.
c. Nyob rau hauv lub grub file, nrhiav kab GRUB_CMDLINE_LINUX_DEFAULT = "".
d. Nkag mus rau cov ntawv hauv qab no ntawm cov quotes (""):
i915.debug_eu=1
Nco tseg Los ntawm lub neej ntawd, tus tsav tsheb GPU tsis tso cai rau cov haujlwm ua haujlwm khiav ntawm GPU ntev dua li qee lub sijhawm. Tus neeg tsav tsheb tua cov haujlwm ua haujlwm ntev li no los ntawm kev rov pib dua GPU los tiv thaiv hangs. Lub hangcheck mechanism ntawm tus tsav tsheb yog neeg xiam yog tias daim ntawv thov khiav hauv qab qhov debugger. Yog tias koj npaj yuav ua haujlwm ntev suav nrog yam tsis muaj qhov debugger txuas, xav txog kev thov GPU: Disable Hangcheck los ntawm kev ntxiv
i915.enable_hangcheck=0
rau tib yam GRUB_CMDLINE_LINUX_DEFAULT kab.
c. Hloov kho GRUB rau cov kev hloov pauv no kom siv tau:
sudo hloov tshiab-grub
d. Rov pib dua.
2. Teeb tsa koj qhov chaw CLI los ntawm kev nrhiav cov ntawv setvars nyob rau hauv lub hauv paus ntawm koj cov cuab yeej teeb tsa.
Linux (sudo):
qhov chaw /opt/intel/oneapi/setvars.sh
Linux (neeg siv):
qhov chaw ~/intel/oneapi/setvars.sh
3. Teeb ib puag ncig
Siv cov kev hloov pauv ib puag ncig hauv qab no los pab txhawb kev debugger rau Intel® oneAPI Qib Zero:
export ZET_ENABLE_PROGRAM_DEBUGGING=1
export IGC_EnableGTLocationDebugging=1
4. Kev kuaj xyuas
Thaum txhua yam npaj txhij, thov khiav cov lus txib hauv qab no kom paub meej tias qhov system configuration yog txhim khu kev qha:
python3 /path/to/intel/oneapi/diagnostics/latest/diagnostics.py –filter debugger_sys_check -force
Qhov ua tau zoo ntawm qhov kev teeb tsa zoo yog raws li hauv qab no:

Sau cov Program nrog Debug Cov Ntaub Ntawv
Koj tuaj yeem siv sample project, Array Transform, kom sai tau pib nrog daim ntawv thov debugger.
1. Kom tau txais sample, xaiv ib qho ntawm cov hauv qab no:
- Siv OneAPI CLI Samples Browser xaiv Array Transform los ntawm qeb pib.
- Download tau los ntawm GitHub*.
2. Nkag mus rau src ntawm sampqhov project:
cd array-transform/src
3. Sau daim ntawv thov los ntawm kev ua kom cov ntaub ntawv debug (-g chij) thiab tua cov kev ua kom zoo (-O0 chij).
Disabling optimization yog pom zoo rau qhov ruaj khov thiab raug debug ib puag ncig. Qhov no yuav pab kom tsis txhob muaj kev tsis sib haum xeeb los ntawm kev hloov pauv rau cov cai tom qab kev ua kom zoo ntawm cov compiler.
Nco tseg Koj tseem tuaj yeem suav cov kev pabcuam nrog kev ua kom zoo dua qub (-O2 chij), uas tuaj yeem pab tau yog tias koj tsom mus rau GPU sib dhos debugging.
Koj tuaj yeem sau qhov program hauv ntau txoj hauv kev. Options 1 thiab 2 siv just-in-time (JIT) muab tso ua ke, uas yog pom zoo kom debug lub sample. Kev xaiv 3 siv ua ntej-ntawm-lub sij hawm (AOT) muab tso ua ke.
- Kev xaiv 1. Koj tuaj yeem siv CMake file configure thiab tsim daim ntawv thov. Xa mus rau lub README ntawm sample rau cov lus qhia.
Nco tseg CMake file muab nrog sample twb hla tus chij -g -O0.
- Kev xaiv 2. Kom suav cov array-transform.cpp sample daim ntawv thov yam tsis muaj CMake file, tawm cov lus txib hauv qab no:
icpx -fsycl -g -O0 array-transform.cpp -o array-transform
Yog tias muab tso ua ke thiab sib txuas ua ke sib cais, khaws cov chij -g -O0 ntawm cov kauj ruam txuas. Cov kauj ruam txuas yog thaum icpx txhais cov chij no kom dhau mus rau lub cuab yeej compiler ntawm runtime. Example:
icpx -fsycl -g -O0 -c array-transform.cpp
icpx -fsycl -g -O0 array-transform.o -o array-transform
- Kev xaiv 3. Koj tuaj yeem siv AOT muab tso ua ke kom tsis txhob ntev JIT muab tso ua ke ntawm lub sijhawm ua haujlwm. JIT muab tso ua ke tuaj yeem siv sijhawm ntev dua rau cov kernels loj hauv qab qhov debugger. Txhawm rau siv Ahead-of-Time compilation hom:
• Rau kev debugging ntawm GPU:
Qhia meej lub cuab yeej uas koj yuav siv rau kev ua haujlwm. Rau example, -device dg2-g10 rau Intel® Data Center GPU Flex 140 Graphics. Rau cov npe ntawm cov kev xaiv uas tau txais kev txhawb nqa thiab cov lus qhia ntxiv ntawm AOT muab tso ua ke, xa mus rau Intel® oneAPI DPC ++ Compiler Developer Guide thiab Reference.
Rau example:
icpx -fsycl -g -O0 -fsycl-targets=spir64_gen -Xs “-device dg2-g10” array-transform.cpp -o arraytransform
Ua ntej-ntawm-Lub Sijhawm muab tso ua ke yuav tsum muaj OpenCLTM Offline Compiler (OC Compiler LOC). Yog xav paub ntxiv, xa mus rau seem "Nruab OpenCLTM Offline Compiler (OCLOC)" ntawm qhov Daim ntawv qhia kev teeb tsa.
• Rau kev debugging ntawm CPU:
icpx -fsycl -g -O0 -fsycl-targets=spir64_x86_64 array-transform.cpp -o array-transform
Pib lub Debug Session
Pib lub sij hawm debug:
1. Pib Intel® Distribution rau GDB * raws li hauv qab no:
gdb-oneapi array-hloov
Koj yuav tsum pom cov lus qhia (gdb).
2. Txhawm rau kom paub tseeb tias cov kernel yog offloaded rau lub cuab yeej zoo, ua cov kauj ruam hauv qab no. Thaum koj ua tiav qhov kev hais kom ua los ntawm (gdb) kom sai, dhau qhov cpu ua, gpu ua or accelerator kev sib cav:
- Rau kev debugging ntawm CPU:
khiav cpu
Examptso zis:
[SYCL] Siv cov khoom siv: [Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz] los ntawm [Intel(R) OpenCL]- Rau kev debugging ntawm GPU:
