| + | Pod 'linux-libc-headers' jest zawartość cvsu, 'scripts' to link symboliczny do 'linux-libc-headers/scripts', jest tam kilka przydatnych rzeczy. W 'sources' są trzymane źródła kerneli, natomiast pod '2.4' i '2.6' są wyciągnięte ze źródeł nagłówki. Pierwsza rzecz, to zassać najnowszy kernel, rozpakować i wyciągnąć z niego nagłówki. W tym celu pierw sprawdzimy które katalogi z nagłówkami nas interesują. | ||

| + | Oto którymi nagłówkami interesowaliśmy się ostatnio. No to teraz dodajemy z obecnego kernela. | ||

| + | No to pozbyliśmy się nieistotnych katalogów. Robimy diffy. | ||

| + | -rw------- 1 mmazur users 794K Sep 28 19:56 specific.diff | ||
| + | </file> | ||
| + | W 'add' jest lista plików dodanych w nowej wersji kernela, w 'del' usuniętych, 'full.diff' to pełny diff (diff -urN), natomiast 'specific.diff' to diff tylko pomiędzy plikami, które istnieją w obu wersjach kernela. Lista w 'add' jest taka długa, bo doszła nowa architektura, ale dodawaniem i wywalaniem plików, to już się ja zajmę. | ||
| + | Główna zabawa jest z nałożeniem 'specific.diff' na ostatnie llh. Trzeba pamiętać o wywaleniu z diffa makr ''__user'', ''__kernel'' i ''__iomem'' (i ewentualnie jakiś innych z linux/compiler.h). Poza tym nic nie powinno includować linux/config.h, a jak coś includuje asm-generic/*, to zostawić mi, bo to jest dziwnie rozwiązane. | ||
