Christoph Hellwig, tuntud Linuxi tuumaarendaja, kes oli m\u00f5nda aega Linux Foundationi tehnilise komitee liige ja esindas hagejat seoses GPL-iga kohtuasjas<\/a><\/noindex> VMware'iga, soovitas<\/a><\/noindex> et karmistada kaitset patenteeritud draiverite sidumise vastu Linuxi tuuma komponentidega, mis on eksportimiseks saadaval ainult GPL litsentsi all olevate moodulite jaoks. Patenteeritud draiverite tootjad kasutavad GPLv2 all avatud koodiga liidese moodulit, et m\u00f6\u00f6da minna GPL-s\u00fcmbolite ekspordipiirangust, kuid selle funktsioonid on piiratud patenteeritud draiveri juurdep\u00e4\u00e4su t\u00f5lkimisega keeldunud API-dele, mis ei ole lubatud otse patenteeritud koodis kasutada.<\/p>\n

Et selliseid man\u00f6\u00f6vreid blokeerida, Christoph Hellwig valmistanud<\/a><\/noindex> Linuxi tuumad, mis tagavad GPL-i s\u00fcmbolitega seotud lipu p\u00e4rimise. Eesm\u00e4rk on p\u00e4rida TAINT_PROPRIETARY_MODULE lipp k\u00f5igis moodulites, mis impordivad s\u00fcmboleid moodulitest, millel on see lipp. Nii et kui GPL-i vahemoodul p\u00fc\u00fcab importida s\u00fcmboleid mitte-GPL moodulist, p\u00e4rib GPL-i moodul TAINT_PROPRIETARY_MODULE m\u00e4rgistuse ja ei saa juurde p\u00e4\u00e4seda tuuma komponentidele, mis on saadaval ainult GPL litsentsiga moodulitele, isegi kui moodul on varem importinud s\u00fcmboleid kategooriast «gplonly». <\/p>\n

Arutelul oli samuti avaldanud<\/a><\/noindex> tagasil\u00fckkamise ettepanek — kui moodul impordib s\u00fcmboleid EXPORT_SYMBOL_GPL, ei tohi selle mooduli poolt eksporditud s\u00fcmboleid importida moodulid, mis ei deklareerita selgelt GPL-iga \u00fchilduvust. St kui moodul impordib s\u00fcmboleid EXPORT_SYMBOL_GPL, peavad k\u00f5ik tema eksporditud s\u00fcmbolid olema k\u00e4sitletud kui EXPORT_SYMBOL_GPL. Christoph Helwig kirjutas<\/a><\/noindex>, mis on 100% n\u00f5us antud ettepanekuga, kuid sellist muudatust ei luba Linus Torvalds, kuna see tooks kaasa suure osa s\u00fcsteemi allhoos\u00fcsteemide k\u00e4ttesaamatuse proprietary draiverite jaoks, kuna draiverite arendamisel kasutavad nad p\u00f5hisisendeid, mis on GPL-i alusel eksporditud.<\/p>\n

Muudatus on tehtud reageerides v\u00e4ljaandmine<\/a><\/noindex> Facebooki inseneri seeria pat\u0161idele, mis rakendavad uut netgpu allhoos\u00fcsteemi, v\u00f5imaldades korraldada otsest andmevahetust (DMA
\nzero-copy) v\u00f5rgukaardi ja GPU vahel, samal ajal t\u00f6\u00f6tades protokolli t\u00f6\u00f6tlemisega CPU abil. Rahulolematus<\/a><\/noindex> arendajate seas tekitas saadavus<\/a><\/noindex> ainult NVIDIA proprietary draiverite rakendamine, kasutades nende draiveritega pakutavat GPL-i kihti. Vastuseks kriitikat<\/a><\/noindex> patchide autor et<\/a><\/noindex>, et allhoos\u00fcsteem ei ole seotud NVIDIA-ga ning selle toetust saab pakkuda ka AMD ja Intel GPU-de tarkvaraliideste jaoks. L\u00f5puks tunnistati netgpu edendamine kernelisse v\u00f5imatuks, kuni t\u00f6\u00f6tav tugi on olemas vabade draiverite, nagu AMDGPU, Intel i915 v\u00f5i Nouveau, alusel. <\/p>\n
