In order to compile GCC, at least the following APIs are missing: - dup2 - alarm - execvp

PANIC: process enqueued for execution multiple times

Consider writing a small set of helper makefile macros such that it should be possible to put a Makefile in each apps/ and tests/ directory to build the individual userspace...

clone() and exec() are not exactly like fork() and exec()

1

There are not-so-subtle differences between fork() and clone() and our exec() vs UNIX exec(): - fork() returns at the point of call and just gives out different return values for...

proctable does not fill in argument data anymore

1

As part of fixing https://github.com/egranata/puppy/issues/57 `proctable_syscall_handler` has been hacked to read ``` #if 0 if (p->args) { strncpy(&pi.args[0], p->args, sizeof(pi.args)); } else { bzero(&pi.args[0], sizeof(pi.args)); } #endif ``` This should...

cowspeak in Python

There exist a few implementations of cowspeak in Python; it would be nice to replace the hacky one I wrote in C++ with a nicer Pythonic one

Higher timer accuracy

Allow loading a new font for the console instead of the default one

Implement a way to load (scan code -> ASCII) configuration data This would allow a user to configure a custom keyboard layout

It should be possible to: a) declare a set of boot phases in some kind of metadata file and have code be autogenerated to support them; b) have convenience functions...
