| H A D | ng_device.h | diff 136673 Mon Oct 18 20:13:57 MDT 2004 glebius Major overhaul. List of functional changes: - Make a single device per single node with a single hook. This gives us parrallelizm, which can't be achieved on a single node with many devices/hooks. This also gives us flexibility - we can play with a particular device node, not affecting others. - Remove read queue as it is. Use struct ifqueue instead. This change removes a lot of extra memcpy()ing, m_devget()ting and m_copymem()ming. In ng_device_receivedata() we enqueue an mbuf and wake readers. In ngdread() we take one mbuf from qeueue and uiomove() it to userspace. If no mbuf is present we optionally block. [1] - In ngdwrite() we create an mbuf from uio using m_uiotombuf(). This is faster then uiomove() into buffer, and then m_copydata(), and this is much better than huge m_pullup(). - Perform locking of device - Perform locking of connection list. - Clear out _rcvmsg method, since it does nothing good yet. - Implement NGM_DEVICE_GET_DEVNAME message. - #if 0 ioctl method, while nothing is done here yet. - Return immediately from ngdwrite() if uio_resid == 0. List of tidyness changes: - Introduce device2priv(), to remove cut'n'paste. - Use MALLOC/FREE, instead of malloc/free. - Use unit2minor(). - Use UID_ROOT/GID_WHEEL instead of 0/0. - Define NGD_DEVICE_DEVNAME, use it. - Use more nice macros for debugging. [2] - Return Exxx, not -1. style(9) changes: - No "#endif" after short block. - Break long lines. - Remove extra spaces, add needed spaces.
