Kungekudala I-NVIDIA yazisa ingxelo yokuqala yesebe elitsha elizinzileyo lomqhubi wayo wemizobo yeNVIDIA 418.43.

Olu hlobo lutsha lomqhubi luya kuphuhliswa ngaphakathi kwesakhelo soMjikelezo oMde weNkxaso (LTS) kude kube nguFebruwari 2020. Kwangelo xesha, uhlaziyo kwiinguqulelo zangaphambili ezihambelanayo zakhutshwa eziyi-NVIDIA 390.116 kunye ne-410.104, apho kwakusebenza khona ii-bugs kunye nenkxaso ye-Linux 5.0 kernel.

I-NVIDIA 418 Iimpawu eziNtsha eziPhezulu

Ngale nkululeko intsha Inkxaso yezi GPU zilandelayo ziye zongezwaI-GeForce GTX 1660 Ti, i-GeForce RTX 2070 i-Max-Q Design, i-GeForce RTX 2080 i-Max-Q Design kunye ne-Tesla V100-SXM3-32GB-H.

Ukongeza, inkxaso yeekhompyuter yeekhowudi kunye neekhowudi zongezwa. (I-NVENC / NVDEC) esetyenziswe kwi-GPUs esekwe kulwakhiwo lweTuring.

I-NVDECODE (NVCUVID) API kwi-Turing GPU yefomathi yekhowudi yevidiyo ye-HEVC yongeza inkxaso kwiifom ze-B kunye neYUV 4: 4: 4 yokumisela.

Ukongeza, inkxaso yokusebenzisa i-CUarrays njenge-buffers yegalelo yongezwe kwi-NVDECODE API, kunye nokubanakho kokukhupha umjelo ofakwe kwikhowudi kunye nokuhamba kwezithuthi ukusuka kwimowudi yoqikelelo lwentshukumo ukuya kwimemori yevidiyo.

Kwakhona, Singagqamisa kolu hlaziyo lokongezwa kwenkxaso yokusebenza kokuSebenza okuKhanyayo okuvela kwi-Turing GPU. ukubala ukuhamba okuphezulu kokusebenza phakathi kwemifanekiso;

Ukubumba kubandakanya ilayibrari entsha libnvidia-opticalflow.so, enokusetyenziselwa ukubala okukhawulezayo kwehardware yeevektri zokuhamba kunye nexabiso lokungafani kwemveliso yestereo. Amaxwebhu kunye nemizekelo yokusebenzisa ipapashwa ngokwahlukeneyo kwi-Optical Stream SDK.

Olunye uphawu olunokuthi lubonakaliswe, sifumana oku kulandelayo:

  • Ukuhlaziywa komqhubi weVDAU.
  • I-installer ye-nvidia-installer yenzelwe ukuqhuba i-depmod kube kanye endaweni yokuphinda kabini (enye kwisigaba sokususa iimodyuli ezindala kunye nenye xa ufaka iimodyuli ezintsha).
  • Kwimodyuli ye- nvidia.ko, inkxaso ye-NVreg_UseThreadedInterrupts ukhetho luyekile, ukuvumela ukuba ubuyele kwisiphatho esidala esiphazamisayo. Ukusukela ngoku ukuya phambili, ngumqhubi omtsha we-IRQ onemisonto emininzi, oxhaswayo ukusuka kuguqulelo 367.44, oya kuhlala esetyenziswa.
  • Yongeza inkxaso yokuqala kubahloli abaxhasa itekhnoloji ye-G-SYNC yokuvumelanisa.
  • Yongezwe inkxaso yokuhanjiswa kwe stereo kwiVulkan API.

Uyifaka njani i-NVIDIA 418.43 driver kwi-Ubuntu nakwiziphumo?

Ukufaka lo mqhubi Kuya kufuneka bazi ukuba umqhubi sele efumanekile kwiLinux (IARM, x86_64), iFreeBSD (x86_64), kunye neSolaris (x86_64). Yintoni esiya kuyo kule khonkco ilandelayoe apho siza kuyikhuphela khona.

Qaphela: ngaphambi kokwenza nayiphi na inkqubo, kubalulekile ukuba ujonge ukungqinelana nalo mqhubi mtsha kunye noqwalaselo lwecompyuter yakho (inkqubo, i-kernel, ii-linux-headers, uguqulelo lweXorg). kwaye asinoxanduva lwayo nangaliphi na ixesha kuba sisigqibo sakho sokwenza okanye hayi.

Khuphella ngoku masiqhubeke nokwenza uluhlu lwabamnyama ukunqanda ukungqubana kunye nabaqhubi basimahla:

sudo nano /etc/modprobe.d/blacklist-nouveau.conf

Kwaye kuyo siza kongeza oku kulandelayo.

blacklist nouveau

blacklist lbm-nouveau

options nouveau modeset=0

alias nouveau off

alias lbm-nouveau off

Uyenzile le nto ngoku siza kuqala inkqubo yethu ukuze uluhlu lwabamnyama luqale ukusebenza.

Nje ukuba inkqubo iqalisiwe, ngoku siza kumisa umzobo wegraphical server (graphical interface) nge:

sudo init 3

Kwimeko apho unescreen esimnyama xa uqala okanye ukuba umise i-graphical server, ngoku siza kungena kwi-TTY ngokuchwetheza loqwalaselo lweqhosha elilandelayo "Ctrl + Alt + F1".

Ukuba sele unenguqulo yangaphambili, Kuyacetyiswa ukuba wenze okungafakwanga ukuthintela ukungqubana okunokubakho:

Kufuneka siphumeze lo myalelo ulandelayo:

sudo apt-get purge nvidia *

Kwaye ngoku lixesha lokwenza ufakelo, kuba oku siza kunika imvume yokuphumeza ngo:

sudo chmod +x NVIDIA-Linux*.run

Kwaye senza nge:

sh NVIDIA-Linux-*.run

Ekupheleni kofakelo kuya kufuneka uqale kabusha ikhompyuter yakho ukuze lonke utshintsho lomthwalo kuqaliso.


Umxholo wenqaku uyabambelela kwimigaqo yethu imigaqo yokuziphatha yokuhlela. Ukuxela impazamo cofa apha.
