## 怎么参与内核开发 Eric Miao 大家交流下我的经验，主要是相互学习： 我先介绍下我的经验吧。原来我是做嵌入式开发的，主要是在 Intel/Marvell 做 PXA/Xscale 这一块的，广  泛用在 PDA 上。也许大家见过过气的 Motorola 的 A1200 等系列的手机，就是用的这款 CPU。 开发过程中发现总是跟随着 Kernel 升级，开发工作很被动。内核树 Kernel 升级到 2.6.14 了，而我们却还在搞 2.6.9。那会儿我们还跟 MontaVista 有合作，所以曾经还搞过 2.4 的内核。PXA27x 上就有些客户在用 2.4，很是崩溃…… 后来我跟 boss 反应，这么开发是不行的，要把我们做的东西推到 mainline Intel HDA，然后结合实际的硬件也能猜个八九不离十。所以声音 debug 是个好的开端。 大家看到 sound/pci/hda/ 下面很多文件里面有很多 snd_pci_quirk 这个结构 (内核代码里面)，这些就是不同机器上不同的非标准配置，或者是 workaround。所以有很多问题，但一旦了解了，修复起来也比较直观。这种 Sound 相关的 Patch 就特别容易被 mainline 接受，改动也不大，很直观，而且也不影响
