Ingo Molnar, tuntud Linuxi tuuma arendaja ja Completely Fair Scheduler'i (CFS) autor, tegi Linuxi tuuma arendajate postituslistis arutamiseks ettepaneku seeria pat\u0161e, mis puudutab enam kui pooli k\u00f5igist tuuma allikakoodifailidest ning tagab tuuma t\u00e4ieliku \u00fcmberkompileerimise kiiruset\u00f5usu 50-80% s\u00f5ltuvalt seadistustest. Tehtud optimeerimine on m\u00e4rkimisv\u00e4\u00e4rne selle poolest, et see h\u00f5lmab ajaloo suurimat muudatusete paketti - ettepanekus on kokku 2297 pat\u0161i, mis muudavad rohkem kui 25 tuhat faili (10 tuhat pealkirjafaili kaustades 'include\/' ja 'arch\/*\/include\/' ning 15 tuhat allikakoodefaili). <\/p>\n

Suurenenud j\u00f5udlus saavutatakse pealkirjafailide t\u00f6\u00f6tlemise meetodi muutmise kaudu. On m\u00e4rgitud, et kolmek\u00fcmne aasta jooksul tuumade arendamisel on pealkirjafailide seisund muutunud probleemseks, kuna failide vahel on palju risttugedeid. Pealkirjafailide struktuuri \u00fcmberkorraldamine v\u00f5ttis rohkem kui aasta ja n\u00f5udis m\u00e4rkimisv\u00e4\u00e4rset \u00fcmbertegemist hierarhias ja s\u00f5ltuvustes. \u00dcmberkorraldamise k\u00e4igus tehti t\u00f6\u00f6, et eraldada t\u00fc\u00fcpide ja API definitsioonid erinevate tuumas\u00fcsteemide jaoks. <\/p>\n

Tehtud muudatuste seas: k\u00f5rge taseme pealkirjade failide eraldamine, inline-funktsioonide \u00fchendavate pealkirjade failide v\u00e4listamine, pealkirjade failide jagamine t\u00fc\u00fcpide ja API jaoks, pealkirjade failide eraldiseisva koostamise tagamine (umbes 80 faili, millel olid teised pealkirjad h\u00e4irivad kaudsed s\u00f5ltuvused), s\u00f5ltuvuste automaatne lisamine failidele «.h» ja «.c», pealkirjade failide samm-sammuline optimeerimine, re\u017eiimi «CONFIG_KALLSYMS_FAST=y» kasutamine, sihip\u00e4rane C-failide konsolideerimine koostamisplokkidesse objektifailide arvu v\u00e4hendamiseks. <\/p>\n

Tulemusena suudeti tehtud t\u00f6\u00f6ga v\u00e4hendada pealkirjafailide suurust, mida t\u00f6\u00f6deldakse eelt\u00f6\u00f6tluse k\u00e4igus 1-2 j\u00e4rku. N\u00e4iteks enne optimeerimist l\u00f5i pealkirjafaili «linux\/gfp.h» kasutamine 13543 koodirea ja 303 s\u00f5ltuva pealkirjafaili lisamise, p\u00e4rast optimeerimist j\u00e4i suurus vaid 181 reale ja 26 s\u00f5ltuvale failile. Teise n\u00e4itena: kui t\u00f6\u00f6delda faili «kernel\/pid.c» ilma plaastrita, lisandub 94 tuhat koodirida, millest suurem osa ei ole pid.c-s kasutusel. Pealkirjafailide eraldamine aitas v\u00e4hendada t\u00f6\u00f6deldava koodi mahtu kolm korda, v\u00e4hendades t\u00f6\u00f6deldud ridade arvu 36 tuhande peale. <\/p>\n

T\u00e4ieliku tuuma uuesti koostamise korral k\u00e4suga «make -j96 vmlinux» test-s\u00fcsteemis n\u00e4itas pat\u0161ide rakendamine haru v5.16-rc7 koostamisaja v\u00e4henemist 231,34 sekundilt 129,97 sekundile (15,5-lt 27,7-le koostiseid tunnis) ning suurendas ka protsessorituumade t\u00f5husust pakkimisel. Inkremendilisel koostamisel on optimeerimise m\u00f5ju veelgi silmatorkavam \u2014 tuuma uuesti koostamise aeg p\u00e4rast pealkirjafailides muudatuste tegemist v\u00e4henes mitu korda (112%-lt 173%-le s\u00f5ltuvalt muudetavast pealkirjafailist). Optimeerimised on hetkel saadaval ainult arhitektuuridele ARM64, MIPS, Sparc ja x86 (32- ja 64-bit).
