最近要学习dfb积累资料

1、http://www.directfb.org/index.php?path=Main%2FDownloads  源码下载路径

     不知道，用的哪个版本的，先下载了两个，1.5.0和1.6.1。

    网页上还有linux fusion的下载，查了查，是为了使用dfb，需要在内核中打的补丁。^ - ^不知道理解对不对。我对下载的网页一直看不大懂。

2、linux kernel oops：

     貌似是linux内核出错的一个什么东东。内核正常运行过程中出错的一个行为。摘自http://en.wikipedia.org/wiki/Linux_kernel_oops

An oops is a deviation from correct behavior of the Linux kernel which produces a certain error log. The better-known kernel panic condition results from many kinds of oops, but others may allow continued operation with compromised reliability. The term does not stand for anything, other than that it is a simple mistake.

When the kernel detects a problem, it prints an oops message and kills any offending process. The message is used by Linux kernel engineers to debug the condition which created the oops and fix the programming error which caused it.

The official Linux Kernel documentation regarding oops messages is in the file Documentation/oops-tracing.txt^[1] of the kernel sources. Some logger configurations may affect the ability to collect oops messages.^[2]

Once a system has experienced an oops, some internal resources may no longer be in service. Even if the system appears to work correctly, undesirable side effects may have resulted from the active task beingkilled. A kernel oops often leads on to a kernel panic once the system attempts to use resources which have been lost.
