Sanarwar ƙaddamar da sabon sigar na aiwatar da kyauta na OpenGL da Vulkan, "Tebur 20.0.0". Kasancewa wannan sigar ce ta farko ta sabon reshe 20.xx kuma hakanan ma ana la'akari dashi a cikin yanayin gwaji Tun daga wannan lokacin za a sake sakin tsayayyen sigar lambar, wanda za a sake fitowa a cikin “Table 20.0.1”.
Ga wadanda basu sani ba da masu kula da Mesa, ya kamata ka sani cewa waɗannan manhajojin buɗe ido ne na Linux akwai don AMD, NVIDIA da kayan aikin Intel. Aikin Mesa ya fara ne azaman buɗaɗɗen tushe na aiwatar da ƙayyadaddun OpenGL (tsarin don nuna zane-zanen 3D mai ma'amala).
A cikin shekarun, aikin ya haɓaka don aiwatar da ƙarin zane-zane APIs, ciki har da OpenGL ES (nau'ikan 1, 2, 3), OpenCL, OpenMAX, VDPAU, VA API, XvMC, da Vulkan. Da dama masu kula na na'urorin yana ba da damar amfani da dakunan karatu na Mesa a cikin muhallin daban-daban, daga kwaikwayon software don kammala hanzarin kayan aiki na GPUs na zamani.
Mesa tana aiwatar da tsarin fassarar mai zaman kansa mai siyarwa tsakanin API mai ƙira kamar OpenGL da kuma direbobin zane a cikin ƙirar tsarin aiki.
Menene sabo a Mesa 20.0.0?
A cikin wannan sabon sigar na masu kula da Mesa 20.0.0 an bayar da cikakken tallafi na OpenGL 4.6 don Intel i965 da AMD radeonsi GPUs, OpenGL 4.5 goyon baya ga AMD (r600) da NVIDIA (nvc0) GPUs, kazalika da goyon bayan Vulkan 1.2 don katunan Intel da AMD.
Direbobin RADV da ANV don AMD GPUs da Intel suna tallafawa API na Vulkan 1.2, yayin da RADV da ACO suna ba da tarin allon inuwa. A cikin RADV da ACO don GPU GFX10 (Navi) suna tallafawa yanayin Wave32.
Ga Intel GPUs dangane da Broadwell da Skylake microarchitectures (Gen8+), sabon direban Iris ana amfani dashi ta tsohuwa, wanda ya isa daidai tare da mai sarrafa i965 a cikin iyawarsa.
Mai kula da Iris ya dogara ne akan gine-ginen Gallium3D, wanda ke kawo ayyukan sarrafa ƙwaƙwalwar ajiya ga direban DRI a cikin kernel na Linux kuma yana ba da mai sa ido kan lafiyar akwatin tare da tallafi don sake amfani da kayan ɓoye abu. PDon kwakwalwan kwamfuta dangane da tsofaffin microarchitectures, har zuwa Haswell, ana barin mai sarrafa i965.
RADV (direban Vulkan don kwakwalwan AMD) da kuma ƙarshen baya don tattara shawan "ACO", wanda aka haɓaka ta hanyar Valve a madadin madadin mai haɗa LLVM, ya ƙara tallafi ga GCN 1.0 / GFX6 (Kudancin Islands) da GCN 1.1 na GPUs / GFX7.
LLVMpipe da RadeonSI direbobi an canza su don amfani da matsakaiciyar ma'ana babu nau'in (IR) na sharan NIR, da nufin yin aiki a matakin mafi ƙanƙanci, ƙarƙashin GLSL IR da teburin IR na ciki. Ingantaccen aikin NIR.
Na sauran canje-canje da aka ambata:
- An ƙara tallafi na live-cache zuwa ga direban RadeonSI, wanda ke tabbatar da gano abubuwa biyu waɗanda aka ƙyanƙyashe.
- OpenGL da direbobin Vulkan na Intel GPUs sun ƙara goyan baya ga kwakwalwan Gen11 (Jasper Lake).
- Direban V3D (don Rasberi Pi) ya ƙara tallafi don geometric shaders daidai da OpenGL ES 3.2, kuma an ba da cikakken tallafi don OpenGL ES 3.1.
- Tulip Vulkan inganta aikin direba don Qualcomm Adreno GPUs.
Idan kana son karin bayani game da shi, zaka iya tuntuba mahada mai zuwa.
Yadda ake girka direbobin bidiyo na Mesa akan Linux?
Kunshin Mesa samu a duk rarraba Linux, don haka girkawarsa mai sauki ne.
Ga waɗanda suke amfani da Ubuntu, Linux Mint da abubuwan ban sha'awa za su iya ƙara matattarar ajiya mai zuwa inda ake sabunta direbobi da sauri.
sudo add-apt-repository ppa:paulo-miguel-dias/mesa -y
Yanzu za mu sabunta jerin fakitinmu da wuraren adana su tare da:
sudo apt update
Kuma a ƙarshe zamu iya shigar da direbobi tare da:
sudo apt upgrade
Ga lamarin wadanda suke Arch Linux masu amfani da abubuwan da suka samo asali, mun girka su da wannan umarnin:
sudo pacman -S mesa mesa-demos mesa-libgl lib32-mesa lib32-mesa-libgl
Domin ko wanene su Masu amfani da Fedora 28 na iya amfani da wannan ma'ajiyar, don haka dole ne su ba da damar yin aikin tare da:
