- 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.
Address for program loading, kernel heap, userspace SHM regions, and
stacks have been changed.
Delete:
toolchain/build
toolchain/local
.userspace_check
Run:
python userspace/build.py clean
make clean-disk
make clean
./build.sh
Also, sleep() as a function (implemented by way of nanosleep) and new
absolute and relative sleep system calls added to newlib.
[ci skip] I damn well know this is going to break CI.
* fix some terminal bugs (some, not all)
* add a serial device to the VFS
* fix up serial so it works better
* add a serial-console application
* fix a bug in some other stuff relating to allocations
* change size of the terminal described by toaru.terminfo
* adds a new system call
Kernel driver sends raw scancodes, compositor or terminal handle the
rest. Support for F* keys will be added soon, in the mean time userspace
applications can know about the status of modifiers (control, shift,
alt, and super).
Compositor actions have been changed to Alt+Left Click for move and
Alt+Middle Click for resize. I'll work on adding more mouse events once
I get them to be faster (they're annoyingly slow at the moment... I want
more accuracy and less latency).
- libc functions not implemented yet
- see `env` for an example of reading variables
- see `esh` for an example of how to set and maintain variables for
sending to other applications
Both of the above will be the basis for the libc implementation.
