With a 2.4.1-pre10 kernel, I noticed that /dev/cpu/microcode was created as a file, and note as a node in the devfs. So, I made this very little patch to correct this:

microcode.c Wed Jan 24 04:47:08 2001 renamed from microcode.c Thu Dec 28 06:28:29 2000 +1 -1

    MICROCODE_MINOR);
 
  devfs_handle = devfs_register(NULL, "cpu/microcode",
-   DEVFS_FL_DEFAULT, 0, 0, S_IFREG | S_IRUSR | S_IWUSR,
+   DEVFS_FL_DEFAULT, MISC_MAJOR, MICROCODE_MINOR, S_IFCHR | S_IRUSR |

S_IWUSR,

    &microcode_fops, NULL);

if (devfs_handle == NULL && error) {
printk(KERN_ERR "microcode: failed to devfs_register()\n");

This should be OK...
I cannot test this feature as I don't have a PIII, but a K6-II... I'll try... Just to know...

I was wondering why /dev/cpu/mtrr was created as a file, not a node, when I found this... For mtrr, it seems to be normal, as I didn't find any informations relative of Major/Minor for this device...

Regards.
