Dotaz: Vyladění jádra

[tuner]

Kde bych prosím Vás našel na internetu nějakou rozsáhlou nápovědu, jak si dobře zkompilovat jádro, jaké jsou nepotřebné věci v jádře... . Jádro zkompilovat umím, většinu nepotřebných věcí jsem taky dal pryč, ale přeci jenom s hodněma volbama se bojím manipulovat.

Odpovědi

[tuner]

Pokud možno i s aktuálníma patchema zvyšujícími výkun

[tuner]

A ještě malá podotázečka, jak se dá zjistit, který modul používá moje síťovka?

[trekker.dk]

lsmod, ten modul by se měl jmenovat podobně jako síťovka, jejíž jméno zjistíš lspci.

Taky by možná mohl používat mii:

$ lsmod
Module                  Size  Used by
...
mii                     5952  1 jméno_modulu_pro_tvojí_síťovku
...

[Liska]

okrem toho mozes pozriet vystup lspci a najst v jadre adekvatny ovladac .. co do sviznosti jadra, skus pozriet tu. co sa tyka tej napovedy, pozri toto a toto samozrejme /usr/src/linux/Documentation

[tuner]

Moje síťovka je Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (rev 11) a druhá realtek, což je celkem jastě 8139too, ale u ty broadband nevim - tg3 ???

[Liska]

presne tak -- tg3 :)

[pasmen]

Jednou se vyplati projit vsechny volby jadra jednu po druhe a precist si cely help k ni, takze opravdu vis co chces a co ne. V podstate neni ceho se obavat, pokud mas v zaloze puvodni jadro pro pripad nouze, nemas co skazit.

Je to zlý?? P.S: omlouvám se, ale nešlo mi to dát do tagu pre.

[kozzi]

no tak dokud to nedokazes dat do pre tagu tak mi je lito timto se fakt neproberu. Jinak pokud se nepletu tak tam nevidim error takze by to melo byt v poho

A jinak varování by měla být "OK", nás programátory zajímaj' jenom errory

[vasek125]

Jo, ale já jsem se na chvilku nedostal k mýmu pc, tak jsem odpovídal z jiného, kde je jen MS paskwil explorer, a tak se nedivim. Teď už by to určitě šlo.

[Michal Kubeček]

A jinak varování by měla být "OK", nás programátory zajímaj' jenom errory

Tak to asi nejsem programátor, svůj kód se snažím psát podle zásady "0 warnings při -Wall". A už se mi to párkrát vyplatilo… :-)

[kozzi]

No já osobně se zajímám jen o errory ale jinak pokud jde o můj projekt tak se snažím taky o 0 warnings pri -Wall ale nekdy se mi tam jeden nebo dva objevi a byva problem to vyresit.

[Filip Jirsák]

To byl jen odkaz na vtip Jinak se taky snažím psát tak, aby eclipse nezobrazovalo ani jeden žlutý trojúhelníček Ale pokud překládám cizí program, warningy nejsou až tak důležité. A ono zrovna jádro asi bude používat konstrukce, které nejsou zrovna obvyklé…

[diverman]

tááák moje oblíbené volby jsou -Wall -ansi -pedantic

[Krystl]

seznam modulu, co potrebujes najdes treba tady:

[Jan Včelák]

Zkuste se podívat na video z avc.sh.cvut.cz - urcite se neco priucite, ja jsem se take priucil.

[vasek125]

Ale řekněte, jak se vyvarovat těm warning, docela mě to kraká. Mám gcc 4.1.

[kozzi]

no napriklad muzes udelat toto make > /dev/null

[pasmen]

Nebo mozna spis make 2> /dev/null

[kozzi]

jo mas pravdu jen je dost nahoubi ze tak se mu schoovaji i errory

[pasmen]

make | sed '/^.*[Ww]arning.*$/d'

[Ritchie]

grep -v

[pasmen]

Soubor x obsahuje 10000 radku

warning: bla bla bla

Vysledky:

[pasmen@nyx tmp]$ time cat x | sed '/^.*[Ww]arning.*$/d' 
real    0m0.107s
user    0m0.097s
sys     0m0.002s
[pasmen@nyx tmp]$ time cat x | grep -v '[Ww]arning' 
real    0m21.110s
user    0m19.641s
sys     0m0.104s

:D

[Michal Kubeček]

To je sice zajímavé, ale vypovídací hodnota je úplně nulová. Co takhle místo cat měřit, jak dlouho běží sed a grep?

[Ritchie]

Dalšího komentáře snad netřeba:

time (cat x | sed '/^.*[Ww]arning.*$/d')
real    0m0.071s
user    0m0.044s
sys     0m0.004s

time (grep -v '[Ww]arning' x)
real    0m0.006s
user    0m0.004s
sys     0m0.000s

[vasek125]

Já měl namysli např. upravit gcc ... Jak to dělaj distribuce při vytváření balíčků? Taky si snad musejí zkompilovat jádro ze zdrojových kódů a potom z toho vytvořit balíček. Ty tam asi takovejch warnings nemaj nebo jo?
