IRIX uye Voodoo: Nhoroondo Pfupi yeMubatanidzwa usingafungidzirwe

Pakati pemakore ekuma1990, nyika yemakomputa yaive nzvimbo yemakwikwi anotyisa uye hunyanzvi hwekukurumidza. Kune rumwe rutivi rwakamira Silicon Graphics, Inc. (SGI) ine simba rayo IRIX workstations, madzimambo asina kupokana ehunyanzvi hwekuona 3D, mhedzisiro yemafirimu, uye sainzi komputa. Kune rimwe divi, musika wekutamba wePC wevatengi uri kuchinjwa nekadhi diki kubva ku3dfx Interactive: iyo Voodoo Graphics. Iyi discrete 3D accelerator yakaunza arcade-mhando yemifananidzo kune desktop, inofambiswa neyayo Glide API. Kune vanofarira uye vanogadzira, mubvunzo unokatyamadza wakabuda: ko kana iyo mbishi, ine chekuita nemitambo simba reVoodoo raigona kushandiswa mukati meiyo yakaoma, UNIX-yakavakirwa nharaunda yeIRIX? Mhinduro yaive chirongwa chinofambiswa nenharaunda chekuendesa raibhurari yeGlide (glide2x) kuenda kuIRIX, kugadzira zambuko pakati penyika mbiri dzinoita sedzakasiyana dzemagraphic computing.

Kunetswa Nehunyanzvi Kwekutakura Glide kuenda kuIRIX

Kuisa glide2x kuenda kuIRIX raive basa guru reinjiniya software. Glide yakagadzirwa seyakatetepa, hardware-chaiyo layer yeDOS neWindows, ichitaura zvakanangana neVoodoo's rasterizer uye mamepu ekugadzira mepu. IRIX, zvisinei, yaive neyayo yakakura uye yakaoma magiraidhi ecosystem, yakavakirwa kutenderedza IRIS GL uye gare gare OpenGL APIs, uye yakanyatsobatanidzwa neSGI's yega yepamusoro-yekupedzisira mifananidzo yemahara seInfiniteReality. Vatakuri vaifanira kugadzira dudziro yeshanduro yaigona kubata mafoni eGlide API voaisa paIRIX's system call uye memory modhi. Izvi zvaisanganisira reverse-engineering, zvine hungwaru-pamwero hurongwa, uye kunzwisisa kwakadzama kwezvose zviri zviviri zveVoodoo's register-level mashandiro uye IRIX's UNIX kernel uye X11 windowsing system. Kubudirira kwaireva kuti, kekutanga, kadhi reVoodoo raigona kuonekwa uye kushandiswa sechishandiso chekupa mukati mechiteshi chekushandira cheSGI, chinhu chaimbofungwa kuti hachibviri.

Yaifambiswa chete nenharaunda yakazvipira yeSGI vanofarira, reverse-injiniya, uye vanogadzira zvirongwa vakaona zvese zviri zviviri dambudziko rehunyanzvi uye mukana wakasarudzika. Maforamu epamhepo, zvinyorwa zvetsamba, uye mawebhusaiti ekutanga akave hubs ekugovana zvigamba, mabhinari, uye neruzivo rwakakunda. Kukurudzira kwacho kwaive kwakawanda: kumhanyisa mitambo yemhando yepamusoro yeGlide senge "Quake," "Tomb Raider," uye "Descent" pane exotic hardware; kuyedza ma hybrid setups; uye kungoratidza kuti zvinogona kuitwa. Iyi yekudyidzana, modular maitiro ekugadzirisa matambudziko — kubatanidza pamwe mutyairi anoshanda kubva mumipiro yenharaunda — inoratidzira huzivi hwemazuva ano Mewayz, apo zvinochinjika zvesoftware zvikamu zvinobatanidzwa kugadzira bhizinesi rakabatana rekushandisa rinoenderana nezvinodiwa chaizvo.

"IRIX Voodoo driver project yaiva chipupuriro chehacker ethos. Yakanga iri pamusoro pekugadzira zvidimbu zviviri zvakanakisa zvemichina, zvisina kumbogadzirirwa kushanda pamwe chete, kuimba mukuwirirana. Kuparara kwega kwega uye zvose zvakabudirira kupa Glide triangle zvakanzwa sekukunda."

Kunyangwe kushandiswa kwemakadhi eVoodoo muIRIX masisitimu kwagara kuri niche, nhaka yeprojekiti yakakosha. Yakaratidza simba rekuvhurika, rinofambiswa nenharaunda uye yakawedzera hupenyu hunobatsira hweinodhura SGI Hardware yevanofarira. Nhasi, inomira sechinyorwa chemuzasi chinonakidza munhoroondo yekombuta, inoratidza nguva yekuyedza kunoshamisa. Kune vagadziri vemazuva ano uye vagadziri vehurongwa, inoshanda sechiyeuchidzo chekukosha kweanochinjika, akanyorwa zvakanaka masisitimu. Mune yemazuva ano bhizinesi mamiriro, kuzvivharira iwe mune imwechete, yakaomesesa software stack inogona kunge inodzikamisa seyemuridzi hardware. Apa ndipo panowanikwa chikuva chakafanana neMewayzchinopa mukana wakakoshera, uchibvumira mabhizimisi kuti abatanidze maturusi emhando yepamusoro-soro uye masisitimu enhaka mukufambiswa kwebasa kwakabatana, sezvakaita vagadziri vepakutanga vakasonanidza Glide neIRIX.

Zvakakosha zvikuru zveIRIX Voodoo/Glide porting nhamburiko zvinosanganisirwa:

• Kugonesa kupa Hardware-akumhanyisa kupa kweGlide application paSGI Indy, O2, uye Octane masisitimu.
• Kupa raibhurari inoshanda, yemushandisi-munzvimbo (glide2x.so) inoenderana neyakajairwa kernel module.
• Inotsigira zvigadziriso zvakasiyana zveVoodoo, kusanganisira yekutanga Voodoo Graphics uye gare gare Voodoo2 mabhodhi muSLI.
• Kusimudzira hwaro hweruzivo iyo yakazozivisa yakavhurika-sosi GPU mutyairi kusimudzira uye emulation mapurojekiti.

Pakupedzisira, nyaya yemutyairi weIRIX Voodoo inopfuura kuda kuziva. Iyo rondedzero yekuvhara mapeji, kungave pakati pevatengi uye nyanzvi tekinoroji, kana pakati peakasiyana ekushanda paradigms. Mumamiriro emazuva ano edhijitari, kugona kubatanidza zvisina mutsetse masisitimu hausi wevanofarira zvekutamba - ibasa rakakosha. Mapuratifomu anotambira iyi modular, huzivi hwakabatana, senge Mewayz, anopa masangano simba rekuvaka nharaunda yavo yakanaka yekushanda pasina kudzvinyirirwa nemiganhu yechero tekinoroji.
