I-Xe ingumshayeli omusha wezithombe ze-Linux kernel zama-iGPU nama-dGPU esimanje
I-Intel ivuliwe isanda kukhipha inguqulo yokuqala ye-de umshayeli omusha we-linux kernel, negama lekhodi "Xe", ibalula ukuthi laba bashayeli abasha Ihloselwe ukusetshenziswa nama-GPU ahlanganisiwe namakhadi ezithombe oqondayo ngokusekelwe ku-Intel Xe architecture esetshenziswa kumahluzo ahlanganisiwe kusukela kumaphrosesa we-Tiger Lake bese ukhetha amakhadi ezithombe zomndeni wakwa-Arc.
Inhloso yokuthuthukiswa komshayeli hlinzeka ngohlaka lokusekela ama-chips amasha, akuboshelwe kukhodi ukusekela izinkundla ezindala. Ukwabelana okusebenzayo okwengeziwe kwekhodi ye-Xe nezinye izingxenye zesistimu engaphansi ye-DRM (Direct Rendering Manager) nayo imenyezelwe.
Ikhodi ekuqaleni yayiklanyelwe ukusekela izakhiwo ezihlukahlukene zehadiwe futhi iyatholakala ukuze ihlolwe kumasistimu e-x86 kanye ne-ARM.
Onjiniyela babashayeli bezithombe ze-Intel's Linux bebesebenza buthule kumshayeli omusha we-Direct Rendering Manager wezithombe ezintsha ze-Gen12/Xe futhi bathathe izinyathelo zokugwema ukuthwala umthwalo omdala we-i915.
Lesi isethulo se-Xe, umshayeli omusha we-Intel GPUs esekela kokubili.
amapulatifomu ahlanganisiwe futhi ahlukahlukene avela e-Tiger Lake (inkundla yokuqala ene Intel Xe Architecture). Inhloso yalo mshayeli omusha wukuba nesisekelo esisha ukusebenza kusukela kulokho akuvinjwa amapulatifomu amadala, ngenkathi futhi uthatha ithuba lokuklama kabusha isilawuli sethu ukuze sikhulise ukwabelana ku-drm isistimu engaphansi, isekela futhi isivumela ukuthi sinikele kakhulu kwabanye Izingxenye ezabiwe njenge-TTM kanye ne-drm/scheduler. Imodeli yememori isuselwe ku-VM bophezela okufana nokuqaliswa kwe-i915. Ngokufanayo i-execbuf Ukuqaliswa kwe-Xe kufana kakhulu ne-execbuf3 ku-i915
Kushiwo ukuthi ukuqaliswa kwamanje kusabhekwa njengenketho yokuhlola yokuxoxwa konjiniyela, okungakalungeli ukuhlanganiswa engxenyeni eyinhloko ye-kernel. Ukusebenza kusilawuli esidala se-i915 akumi futhi ukunakekelwa kwaso kuzoqhubeka. Isilawuli esisha se-Xe sihlelelwe ukuthi silunge ngo-2023.
Ikhodi isesigabeni lapho isivele isebenza futhi inolwazi
ukusekelwa kwamapulatifomu amaningi njenge-Tiger Lake, ngokusekelwa kokuqala
isetshenziswe e-Mesa (ye-Iris ne-Anv, abashayeli bethu be-OpenGL kanye ne-Vulkan), kanye
njengaku-NEO (ye-OpenCL ne-Level0). I-Mesa MR [2] kanye ne-NEO zishicilelwe
Ukuqaliswa kuzokhishwa esidlangalaleni ekuqaleni konyaka ozayo. Siphinde sibe ne-suite. kusuka ku-IGT ye-XE ezofakwa ohlwini lwe-IGT maduze.
Kusilawuli esisha, iningi lekhodi yokuxhumana nezikrini libolekwe kumshayeli we-i915 futhi, ngokuzayo, onjiniyela bahlela ukuqinisekisa ukwabelana ngale khodi kuzo zombili izilawuli ukugwema ukuphindaphinda kwezingxenye ezijwayelekile (manje ikhodi enjalo imane yakhiwe kabusha kabili, kodwa ezinye izinketho zokwabelana ngekhodi kuxoxwa ngazo).
Imodeli yenkumbulo ku-Xe isondelene kakhulu nokuqaliswa kwemodeli yenkumbulo ye-i915, futhi ukuqaliswa kwe-execbuf kufana kakhulu ne-execbuf3 kusuka kukhodi ye-i915. Ukuze kusekelwe i-OpenGL ne-Vulkan graphics APIs, ngaphezu komshayeli we-Linux kernel, iphrojekthi iphinde yalungiselela izinguquko ukuze abashayeli be-Iris ne-ANV Mesa basebenze ngemojula ye-Xe.
Ngesimo saso samanje, isixhumanisi se-Xe-Mesa sesivele sivuthwe ngokwanele ukuthi singasebenzisa iziphequluli nemidlalo esekelwe ku-GNOME, OpenGL kanye ne-Vulkan, kodwa kusenezinkinga ezithile nezimbungulu, phakathi kwezinye izinto, ezibangela ukuba iphahlazeke. Futhi, awukho umsebenzi wokuthuthukisa ukusebenza owenziwe okwamanje.
Ekugcineni kufanelekile ukusho lokho Uhlelo lwe-Intel wukuqhubeka nokusebenza kuyo futhi uyihlanganise ne-Mesa ezingxenyeni ezincane, kodwa okusalungiswa kwakho okuyinhloko kwayo yonke into kuzonamathela njengoba uya ukuze uvumele ukufakazela lula.
Uma unjalo unentshisekelo yokwazi okwengeziwe ngayo, ungabheka imininingwane kufayela le- isixhumanisi esilandelayo.
