Qala ka Intel® Distribution bakeng sa GDB* ho Linux* OS Host
Qala ho sebelisa Intel® Distribution bakeng sa GDB* bakeng sa ho lokisa lits'ebetso. Latela litaelo tse ka tlase ho seta debugger ho lokisa lits'ebetso ka lithollo tse theotsoeng ho lisebelisoa tsa CPU le GPU.
Intel® Distribution bakeng sa GDB* ea fumaneha e le karolo ea Intel® oneAPI Base Toolkit. Bakeng sa tlhaiso-leseling e batsi ka lithulusi tsa OneAPI, etela leqephe la sehlahisoa.
Etela ho Lintlha tsa Phatlalatso leqepheng la bakeng sa tlhahisoleseling mabapi le bokhoni ba bohlokoa, likarolo tse ncha, le litaba tse tsebahalang.
U ka sebelisa SYCL* sample khoutu, Array Transform, ho qala ka Intel® Distribution bakeng sa GDB*. The sample ha e hlahise liphoso 'me e mpa e bontša likarolo tsa debugger. Khoutu e sebetsana le likarolo tsa lenane la ho kenya ho latela hore na li lekana kapa li sa tloaeleha 'me li hlahisa lihlahisoa tse ngata. U ka sebelisa sample ho lokisa CPU kapa GPU ka bobeli, ho hlakisa sesebelisoa se khethiloeng ka khang ea mola oa taelo. Leha ho le joalo, hlokomela hore GPU debugging e ka hloka litsamaiso tse peli le tlhophiso e eketsehileng bakeng sa ho lokisa liphoso ka hole.
Lintho tse hlokahalang
Haeba u ikemiselitse ho lokisa GPU, kenya li-driver tsa morao-rao 'me u lokise sistimi ea hau hore e li sebelise. Sheba ho Tataiso ea ho Kenya Lisebelisoa tsa Intel® oneAPI bakeng sa Linux* OS. Latela litaelo Kenya Bakhanni ba Intel GPU ho kenya li-driver tsa GPU tse tsamaellanang le sistimi ea hau.
Ho feta moo, o ka kenya katoloso ea Visual Studio Code* bakeng sa ho lokisa GPU ka Intel® Distribution bakeng sa GDB*. Sheba ho Ho sebelisa Visual Studio Code ka Intel® oneAPI Toolkits Guide.
Theha GPU Debugger
Ho theha GPU debugger, o tlameha ho ba le phihlello ea metso.
HLOKOMELA Nakong ea ho lokisa kernel, GPU ea emisoa 'me tlhahiso ea video ha e fumanehe mochining oo u o batlang. Ka lebaka la sena, u ke ke ua khona ho lokisa GPU ho tsoa ho sistimi e shebiloeng haeba karete ea GPU ea sistimi e boetse e sebelisoa bakeng sa tlhahiso ea litšoantšo. Tabeng ena, hokela mochine ka ssh.
1. Haeba u ikemiselitse ho lokisa GPU, ho hlokahala Linux Kernel e ts'ehetsang bothata ba GPU.
a. Latela litaelo ho Intel® software bakeng sa bokhoni bo akaretsang ba GPU ho jarolla le ho kenya li-driver tse hlokahalang.
b. Numella ts'ehetso ea debug ea i915 ho Kernel:
a. Bula terminal.
b. Bula grub file ho /etc/default.
c. Ka har'a grub file, fumana mola GRUB_CMDLINE_LINUX_DEFAULT=””.
d. Kenya mongolo o latelang lipakeng tsa mantsoe a qotsitsoeng (“”):

d. Qala bocha.
2. Theha tikoloho ea hau ea CLI ka ho fumana sengoloa sa li-setvars se motso oa sesebelisoa sa hau sa lisebelisoa.

Kopanya Lenaneo ka Boitsebiso ba Debug
U ka sebelisa sample projeke, Array Transform, ho qala ka potlako ka debugger ea kopo.
1. Ho fumana sample, khetha efe kapa efe ea litsela tse latelang:
- Sebelisa e 'ngoeAPI CLI Sample Browser ho khetha Array Transform ho tsoa sehlopheng sa ho Qala.
- Khoasolla ho tsoa ho GitHub*.
2. Tsamaea ho src ea sample morero:
