Linux内核DRM实现分析——基于i915
1 接口
我们先看看i915_drv.c里面申明的driver变量：
static struct drm_driver driver = {
/* don't use mtrr's here, the Xserver or user space app should
* deal with them for intel hardware.
*/
.driver_features =
DRIVER_USE_AGP | DRIVER_REQUIRE_AGP | /* DRIVER_USE_MTRR |*/
DRIVER_HAVE_IRQ | DRIVER_IRQ_SHARED | DRIVER_GEM,
.load = i915_driver_load,
.unload = i915_driver_unload,
.open = i915_driver_open,
.lastclose = i915_driver_lastclose,
.preclose = i915_driver_preclose,
.postclose = i915_driver_postclose,
.suspend = i915_suspend,
.resume = i915_resume,
.device_is_agp = i915_driver_device_is_agp,
.enable_vblank = i915_enable_vblank,
.disable_vblank = i915_disable_vblank,
.irq_preinstall = i915_driver_irq_preinstall,
.irq_postinstall = i915_driver_irq_postinstall,
.irq_uninstall = i915_driver_irq_uninstall,
.irq_handler = i915_driver_irq_handler,
.reclaim_buffers = drm_core_reclaim_buffers,
.get_map_ofs = drm_core_get_map_ofs,
.get_reg_ofs = drm_core_get_reg_ofs,
.master_create = i915_master_create,
.master_destroy = i915_master_destroy,
#if defined(CONFIG_DEBUG_FS)
.debugfs_init = i915_gem_debugfs_init,
.debugfs_cleanup = i915_gem_debugfs_cleanup,
#endif
.gem_init_object = i915_gem_init_object,
.gem_free_object = i915_gem_free_object,
.gem_vm_ops = &i915_gem_vm_ops,
.ioctls = i915_ioctls,
.fops = {
.owner = THIS_MODULE,
.open = drm_open,
.release = drm_release,
.ioctl = drm_ioctl,
.mmap = drm_gem_mmap,
.poll = drm_poll,
.fasync = drm_fasync,
#ifdef CONFIG_COMPAT
.compat_ioctl = i915_compat_ioctl,

安装ubuntu时，grub默认安装在第一个硬盘(hd0)的mbr中，其实就是把引导文件boot.img写入硬盘的mbr,当然,用户也可以选择不写入硬盘mbr 而是写入linux分区的引导扇区。grub以fd表示软盘，hd表示硬盘(包含IDE和SCSI硬盘)。以前版本的grub其设备是从0开始编号,分区也是从0开始,主分区从0-3,逻辑分区从4开始, ......

很久没来博客了，这都拜公司那可恶的Websense所赐，最近时常发现有一些Linux命令莫名其妙的忘记了，也许是少用了，或者是老了：（于是想到索性在这里写一边文章记录一下，以便日后参考。
1、删除乱码文件：
# ll -i (获得文件节点号)
# find ./ -inum 节点号 -print -exec rm {} -rf \; (巧用find删除)
2、find与xargs� ......
