This is the last version of automake without a warning for Cygnus-style
trees, and is the recommended version for building newlib. An older
autoconf is not necessary to make things work. Just run this, it should
install correctly to your local build directory.
- Tasklets are essentially kernel threads. Still working on passing
arguments to them, but they essentially just run functions and have
special names like [[kttydebug]]. Eventually, I want disk scheduling
and various (non-interrupt-driven) drivers running on these, but I'm
still not sure how stable they are.
- Fix the scheduler so it supports not having anything to run. This took
some tracking of what's running, and then inserting some liberal
sleeps. Doesn't appear to break anything. Makes the system work when
you try to sleep with only one process "running", so that's good.
- Start working on reimplementing the old kernel shell, but this time as
a tasklet running in the background over serial. Probably going to try
to add all the same features as before (tab completion, history, rich
editing), but it may take some time to get it all in there. This
console is mostly focused on helping with debugging EXT2 and other
future stuff.
They now use interrupts and thus can be blocked on without sitting in a
busy loop. Not sure if they still work perfectly, need to debug. Works
fine with the console "serial" stuff in qemu.
Todo: Investigate further.
I am going to replace it after I finish making the ANSI escape parser
modular again (it became a bit less modular during the development of
this terminal).
These changes are part of an effort to make the terminal more efficient.
Another goal is to make the terminal use the "new-style" compositor
interface, which is still in development.
Major speed improvement, though it might make things like "Scale
windows" look a bit less polished; windows that are scaled up in scale
mode are rendered with bilinear scaling. Will probably replace with the
FAST/GOOD macros later.
Also, add the framework for Alt+Tab window picking (not implemented yet)
