UAron Plattner, omnye wabaphuhlisi abaphambili babaqhubi beNVIDIA, yazise ngokuthumela ubume benkxaso yeprothokholi yeWayland kwicandelo lovavanyo lomlawuli we-R515, apho i-NVIDIA ibonelele ngekhowudi yemvelaphi yawo onke amalungu enqanaba le-kernel.
Kufuneka kuqatshelwe ukuba kwiindawo ezininzi, Inkxaso yeprotocol yeWayland kumqhubi weNVIDIA ayikafikeleli kwi-parity kunye ne-X11 ehambelanayo. Kwangelo xesha, i-lag ingenxa yemicimbi yomqhubi we-NVIDIA kunye nemida ngokubanzi yeprotocol ye-Wayland kunye neeseva ezidibeneyo ezisekelwe kuyo.
Kukho iindawo ezininzi apho umqhubi we-NVIDIA R515 engenawo umlinganiso phakathi kwe-X11 kunye ne-Wayland. Oku kunokuba ngenxa yothintelo lomqhubi ngokwawo, iWayland protocol, okanye umqambi othile weWayland osetyenziswayo. Ngokuhamba kwexesha, olu luhlu lulindeleke ukuba lube lufutshane njengoko umsebenzi olahlekileyo uphunyezwa kumqhubi kunye namacandelo anyukayo, kodwa oku kulandelayo kubamba imeko njengoko kukhutshwe le nguqulo yomqhubi. Qaphela ukuba olu luhlu luthatha umqambi ngenkxaso epheleleyo enengqiqo yokwandiswa kweprothokholi enxulumene nemizobo yeWayland.
Ngaphakathi imida ekhoyo ezi zilandelayo zisakhankanywa:
- Ithala leencwadi yeebda, eyenza iindlela zokukhawulezisa i-hardware ye-video-post-processing, ukudibanisa, ukuboniswa kunye nokucacisa, ayinankxaso eyakhelwe-ngaphakathi yeWayland. Ithala leencwadi alinakusetyenziswa neXwayland nayo.
- IWayland neXwayland azixhaswa lithala leencwadi leNvFBC (NVIDIA FrameBuffer Capture) isetyenziselwa ukuthathwa kwesikrini.
- Imodyuli ye-nvidia-drm ayixeli iimpawu zokuhlaziya eziguquguqukayo ezifana ne-G-Sync, ezithintela ukuba zisetyenziswe kwiindawo ezise-Wayland.
- Kwimeko esekwe eWayland, imveliso kwizikrini zokwenyani zokwenyani, umzekelo iyahambelana neqonga leSteamVR, alifumaneki ngenxa yokungasebenzi kwendlela ye-DRM yokuqeshisa, ebonelela ngezibonelelo eziyimfuneko ze-DRM ukwenza umfanekiso we-stereo onezithinteli ezahlukeneyo.
- I-Xwayland ayiluxhasi ulwandiso lwe-EGL_EXT_platform_x11.
- Imodyuli ye-nvidia-drm ayixhasi i-GAMMA_LUT, DEGAMMA_LUT, CTM, COLOR_ENCODING, kunye neepropati ze-COLOR_RANGE, ezifunekayo kwinkxaso epheleleyo yokulungiswa kombala kubaphathi abadibeneyo.
- Xa usebenzisa i-Wayland, ukusebenza kwe-nvidia setup utility kulinganiselwe.
- Nge-Xwayland kwi-GLX, ukuzoba isithinteli semveliso kwikhusi (i-buffer yangaphambili) ayisebenzi ngebuffering kabini.
Ngelixa kwicala le Unyino lweprothokholi yeWayland kunye neeseva ezidibeneyo:
- Imisebenzi efana I-stereo ngaphandle, i-SLI, i-Multi-GPU Mosaic, iSitshixo seSakhelo, iGenlock, Amaqela okutshintsha kunye neendlela zokubonisa eziphambili (i-warp, blend, pixel shift, kunye ne-YUV420 emulation) ayixhaswanga kwiprothokholi yeWayland okanye iiseva ezidibeneyo. Kubonakala ukuba, ukuphumeza umsebenzi onjalo, kuya kufuneka ukuba udale izandiso ezintsha ze-EGL.
- Akukho API eyamkelekileyo eqhelekileyo evumela iiseva ezihlanganisiweyo zeWayland ukuba zicime imemori yevidiyo nge-PCI-Express Runtime D3 (RTD3).
- IXwayland ayinanto yesixhobo esinokusetyenziswa kumqhubi weNVIDIA ukulungelelanisa unikezelo lwesicelo kunye nemveliso yesikrini. Ngaphandle kongqamaniso olunjalo, phantsi kweemeko ezithile, ukubonakala kokuphazamiseka okubonakalayo akubandakanywanga.
- Iiseva ezidityanisiweyo zaseWayland sukuxhasa umboniso wokuphindaphinda (i-mux) esetyenziswa kwii-laptops ezine-GPU ezimbini (ezidibeneyo kunye ne-discrete) ukudibanisa ngokuthe ngqo i-GPU edibeneyo kwisiboniso esidibeneyo okanye sangaphandle. Kwi-X11, umboniso "mux" unokutshintsha ngokuzenzekelayo xa i-app yesikrini esigcweleyo iphuma nge-GPU ecacileyo.
- Unikezelo olungathanga ngqo nge-GLX alusebenzi eXwayland, njengoko ukuphunyezwa kwe-GLAMOR ye-2D yokukhawulezisa uyilo ayihambelani nokuphunyezwa kwe-EGL ye-NVIDIA.
- Ulwaleko lwehardware aluxhaswanga zizicelo zeGLX ezisebenza kwindawo esekwe eXwayland.
Gqibela ukuba unomdla wokwazi okungakumbi ngayo, ungazijonga iinkcukacha kwi ukulandela ikhonkco.
