| | | | | | | | | | | | | | The only relevant sign of port being ready is its board->ready since now. Remove all other flags for this purpose which are set almost on the same place. Move ports inside the board to be sure that nobody will grab reference to the port without being sure that it exists.

* SGI Altix mmtimer: allow larger number of timers per nodeDimitri Sivanich2008-04-301-156/+244
| | | | | | | | | | | | | | | | The purpose of this patch to the SGI Altix specific mmtimer (posix timer) driver is to allow a virtually infinite number of timers to be set per node. Timers will now be kept on a sorted per-node list and a single node-based hardware comparator is used to trigger the next timer.

* tty_ioctl: soft carrier handlingAlan Cox2008-04-301-6/+27
| | | | | | | | | | | | | First cut at moving the soft carrier handling knowledge entirely into the core code. One or two drivers still needed to snoop these functions to track CLOCAL internally. Instead make TIOCSSOFTCAR generate the same driver calls as other termios ioctls changing the clocal flag. This allows us to remove any driver knowledge and special casing. Also while we are at it we can fix the error handling.

| | | | | | | | | | | | | | | | | Refine these behaviors in the N_TTY line discipline: 1) Handle the signal characters consistently when received in a stopped TTY so that SUSP (typically ctrl-Z) behaves like INTR and QUIT in resuming a stopped TTY. 2) Adjust the order in which the IGNCR/ICRNL/INLCR processing is applied to be more logical and consistent with the behavior of other Unix systems.

| | | | | | | | | | | | | | | | | | | | | Afaics, currently there are no kernel problems with ptracing init, it can't lose SIGNAL_UNKILLABLE flag and be killed/stopped by accident. The ability to strace/debug init can be very useful if you try to figure out why it does not work as expected. However, admin should know what he does, "gdb /sbin/init 1" stops init, it can't reap orphaned zombies or take care of /etc/inittab until continued. It is even possible to crash init (and thus the whole system) if you wish, ptracer has full control.
