Andreas Kling	19b9401487	Reduce kmalloc() traffic in directory iteration. ... Pass the file name in a stack-allocated buffer instead of using an AK::String when iterating directories. This dramatically reduces the amount of cycles spent traversing the filesystem.	2018-11-13 00:17:30 +01:00
Andreas Kling	f1404aa948	Add primitive FIFO and hook it up to sys$pipe(). ... It's now possible to do this in bash: cat kernel.map | fgrep List This is very cool! :^)	2018-11-12 01:28:46 +01:00
Andreas Kling	03a8357e84	Implement sending signals to blocked-in-kernel processes. ... This is dirty but pretty cool! If we have a pending, unmasked signal for a process that's blocked inside the kernel, we set up alternate stacks for that process and unblock it to execute the signal handler. A slightly different return trampoline is used here: since we need to get back into the kernel, a dedicated syscall is used (sys$sigreturn.) This restores the TSS contents of the process to the state it was in while we were originally blocking in the kernel. NOTE: There's currently only one "kernel resume TSS" so signal nesting definitely won't work.	2018-11-07 21:19:47 +01:00
