Ubuntu 10.04與sk98lin

前面來點前言，我用的主機板是P5Q-E，這塊主機板不錯，C/P值也頗高，內建的Gigabit LAN Controller是MARVELL，要說差也不差，但Linux內建的Driver(skge/sky2)就是很鳥，因此都得用原廠的sk98lin，但每次kernel一升級，就經常無法編譯通過，這次Ubuntu 10.04同樣遇到了！
因為Ubuntu 10.04還太新了，目前沒google到patch，我所幸自己試著抓抓改改，目前看來應該ok！

安裝時編譯錯誤程式碼如下：
/tmp/Sk98IpXJpMHrIbXnZSVQLQbMS/all/skge.c: In function 『SkGeTestIsr』:
/tmp/Sk98IpXJpMHrIbXnZSVQLQbMS/all/skge.c:1750: error: 『TASK_NORMAL』 undeclared (first use in this function)

/tmp/Sk98IpXJpMHrIbXnZSVQLQbMS/all/skge.c:1780: warning: passing argument 2 of 『request_irq』 from incompatible pointer type
include/linux/interrupt.h:117: note: expected 『irq_handler_t』 but argument is of type 『int (*)(int, void *)』
/tmp/Sk98IpXJpMHrIbXnZSVQLQbMS/all/skge.c:1790: error: 『TASK_UNINTERRUPTIBLE』 undeclared (first use in this function)
/tmp/Sk98IpXJpMHrIbXnZSVQLQbMS/all/skge.c:1790: error: implicit declaration of function 『schedule_timeout』
make[2]: *** [/tmp/Sk98IpXJpMHrIbXnZSVQLQbMS/all/skge.o] Error 1
make[2]: *** Waiting for unfinished jobs....

注意到，
Q1:
TASK_NORMAL、TASK_UNINTERRUPTIBLE 沒定義

Q2:
schedule_timeout 無法被skge.c直接呼叫

cscope之後發現 TASK_NORMAL、TASK_UNINTERRUPTIBLE、schedule_timeout 都在 sched.h中。

因此，修改 DriverInstall/sk98lin.tar.bz2 壓縮檔中的 2.6/skge.c
(DriverInstall/sk98lin.tar.bz2:/2.6/skge.c)
