Kernel: Optimize processes' memory management
...
Memory regions are now stored in a sorted array. This allows O(nlogn)
lookup for address validation instead of the old linear lookup.
Now inserting new regions is also O(nlogn) instead of the old constant
time, but lookups are **much** more frequent

This allows userspace to use both registers
2025-11-13 04:20:53 +02:00
9537922acc
Kernel: Implement proper memory region splitting
...
Memory regions are now splitted when they get munmapped, mprotected, or
mmapped with MAP_FIXED. This is used by couple of ports, and without
this we were just leaking up memory or straight up crashing programs.

04d24bce70
Kernel/LibC: Implement {recv,send}msg as syscalls
...
This also removes the now old recvfrom and sendto syscalls. These are
now implemented as wrappers around recvmsg and sendmsg.
Also replace unnecessary spinlocks from unix socket with mutexes
2025-11-10 01:40:33 +02:00

391fc0c4c2
Kernel: Don't crash if Ext2 filesystem doing too many fileops
...
I had a hardlimit of 10 block buffers and if they ran out, the kernel
would crash. this patchs increases the number of buffers to 16 and
removes the crash condition when they run out :D

f926e599fa
Kernel: Zero initialize Processors
...
This moves processor array to .bss reducing data size by 8192 bytes :)
This needed GCC updated to 15.2.0 because of an internal compiler error
I found :)

Kernel: Replace all occurances of BSB with BSP
2025-08-25 17:11:32 +03:00
350ae90bb6
Kernel: Make all futexes shared
...
Some stuff tries to use shared futexes so make them all shared. Private
futexes would be faster as they are process specific but supporting both
would need some reworks

Kernel: Make userspace stack on-demand allocated
...
Also bump the hardlimit of stack size from 512 KiB->32 MiB. This still
feels quite low but is much better than before :D
2025-08-07 16:43:05 +03:00
f5bbcc017c
Kernel: Only send one smp message when reserving a range
...
This was causing some kernel panic because processors ran out of smp
message storage when reserving large areas.
Also most of the time there is no need to actually send the SMP message.
If process is mapping something to just its own address space, there is
no need for a TLB shootdown. Maybe this should be only limited to kernel
memory and threads across the same process. I'm not sure what the best
approach here and it is better to send too many invalidations that too
few!
