Bananymous 1bd33e76e5 cat/cat-mmap: print newline if file doesn't end in one 2024-01-02 23:27:13 +02:00
Bananymous 9fa13079f2 Kernel: Implement supplementary groups
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...

This allows users to open framebuffer/input files without root.

Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.

Bananymous 79a15132da BAN: Cleanup HashSet

was added.

Bananymous 3963afe343 BAN: Add unstable version of hash map
This version differs only when doing rebucket. If rebucket fails,
the whole hash map is invalidated. This allows rebucketing to use
moving instead of copying.

Bananymous c773e2ed07 LibC: Optimize malloc even further
aoc2023/day12 now runs in 3.5 seconds on my machine. This is way
better than the old almost hour.

Bananymous c4186bd5f0 LibC: Compile with -O2 optimizations
I have no idea why libc had no optimizations enabled.

Weird thing is that memcpy optimized to infinite loop if I kept the
__restrict__ attributes in pointers. I don't think there was any ub.

Bananymous 5f640da166 LibC: Optimize malloc by a lot
I now cache first free node in malloc_pool and whether the node is
last or not. There allow doing less full iterations over the whole
malloc pool.

Malloc is still unbearably slow and I will have to write a proper
fast malloc at some point. With this patch running aoc2023/day12 is
atleast possible. Probabaly will take closer to an hour...
