apio	6f3ed70363	kernel+libluna: Avoid scrubbing when the memory is going to be overwritten anyway ... This is the case for objects with constructors and temporary memory which is filled afterwards.	2023-08-27 20:48:33 +02:00
apio	798a6d63aa	libluna: Document Bitset.h	2023-08-23 14:45:53 +02:00
apio	3f1e6fc2ff	libluna+kernel: Move luna/Syscall.h to the kernel API directory ... A kernel-specific header has nothing to do in libluna.	2023-08-23 14:35:21 +02:00

apio	95a33c484e	kernel+libc: Add a memstat() syscall ... We can finally show memory usage in userspace. This could have been done using sysfs, but I'm lazy and don't want to implement that. Maybe in the next release?	2023-08-17 20:15:32 +02:00
apio	4a654bf093	kernel: Handle OOMs better and without deadlocking ... Use a separate task to do it. Also fix a bug where the init thread would get no kernel stack ever since 5f698b477.	2023-08-17 20:14:33 +02:00
apio	d43590e68c	kernel: Improve Your Disk IO performance by 500% with this One Trick! ... The trick being caching lol.	2023-08-16 14:54:13 +02:00

apio	54cc80f649	kernel/ATA: Replace a manually allocated buffer with Buffer ... This also lets us keep it empty unless it is used, in which case we resize it (if it wasn't already resized).	2023-08-16 09:15:00 +02:00
apio	b8f81502b8	kernel: Fix some debug messages that are not shown by default	2023-08-16 09:03:25 +02:00
