Fixed a bug in PM: sending of reply messages didn't check if destination process is still alive. This caused a panic in some situations, e.g., when all processes are killed on a shutdown.

Improved NOTIFY system: fixed a minor error, ignore pending notifications on SENDREC system calls. To be done: resource (buffer pool) management; make it structurally impossible to run out of buffers.

Optimized scheduling code. Old code is still available withing DEAD_CODE and NEW_SCHED_Q definitions. Some minor problems are being traced at the moment. This commit is meant to backup my files. --- Jorrit

this test breaks on the new pre-i/o i/o buffer check. it wants to read more than its buffer allowed, so it is reasonable that it breaks. reducing read request size 'fixes' it.

New NOTIFY system call! Queued at kernel. Duplicate messages (with same source and type) are overwritten with newer flags/ arguments. The interface from within the kernel is lock_notify(). User processes can make a system call with notify(). NOTIFY fully replaces the old notification mechanism.

If the file (created by setup) exists, use boot parameters from there for the boot floppy instead of copying it from the current root partition. This makes making a boot floppy at installation time before booting from the new system possible (conveniently).

Some #defines for removing registered irq handler
Ben Gras
2005-05-12 16:07:15 +00:00
d0c3e8f818
. added rm_irq_handler which un-links an irq handler from the linked list of handlers, callable by irqctl system call . workaround for hanging keyboard bug after shutdown.. if key is pressed during or after shutdown procedure, keyboard stops working. It looks like irq 1 gets stuck high if no keyboard reading is done (e.g. because the irq is masked or tty driver has exited). Workaround is to leave irqs enabled until the last second, and call shutdown() immediately after the last driver has stopped (tty task). This way the chance of an unserviced interrupt occuring is negligible.
