The Blockdev driver module
Blockdev
Description:
A simple block device driver
Driver inodes:
The driver inode in /dev is usually created by
mknod /dev/Blockdev c major minor
If another major is needed it can be specified by the
Blockdev_major option to insmod:
insmod Blockdev.o Blockdev_major=new_major
Driver inodes:
All driver generated with LDDK have debugging information
compiled into the code that can be configured with the dbgMask
option to insmod. The bits of dbgMask specifies the debugging verbosity:
- Bit-0 Flag for setting all options=on
- Bit-1 function entrys
- Bit-2 function exits
- Bit-3 branches
- Bit-4 data given to functions
- Bit-5 interrupts
- Bit-6 register info
- Bit-7 reserved
For example:
insmod Blockdev.o dbgMask=0x06
logs all function entrys and exits to the kernel log daemon.
