Bananymous fbef90f7cb Kernel/LibC: Write cxx abi with proper locking 2024-03-26 02:28:10 +02:00
Bananymous a9db4dd9a3 Kernel: NVMe Queue max simultaneous commands is dependent on arch 
This allows mask to be atomic on 32 bit architectures

Bananymous b5aae34d86 Kernel: Specify template paramenters where they cannot be deduced 2024-03-22 15:41:15 +02:00
Bananymous 7f029b2713 Kernel: Allow Processor compilation for i386 targets 
This is achieved by rewriting some inline assembly and changing
ProcessorID to be 32 bit value. For some reason if processor id
is 8 bits gcc runs out of 8 bit registers on i386.

Bananymous 0424082e7b Kernel: Only compile lai for x86_64 targets

Bananymous 26ed689d30 Kernel: Remove old GDT, IDT and MMU code from i386 
It will be easier to just rewrite them
 2024-03-22 12:47:34 +02:00

 2024-03-21 21:59:09 +02:00
Bananymous 7d1b7436d4 LibC: Dummy ctr* files for i386 
This allows compilation of libc for i386 targets
 2024-03-21 15:20:20 +02:00
Bananymous 65750586b6 LibC: Use GCC builtins for math functions 2024-03-21 15:19:44 +02:00
Bananymous 62f6128ba1 Kernel: Cleanup NVMe Queue command submission 
There is techically a race condition on thread sleep and checking
done mask. This patch allows read to success even if this race
condition is hit, although the full timeout has to be waited.

This can be fixed in future with some sort of wait queues that
can properly handle this race condition.

Bananymous e447d5fccf All: remove obsolete gitignore files 
These have not been in use for almost a year
 2024-03-18 15:28:46 +02:00
Bananymous 090c3c9930 Kernel: NVMe queues now supports upto 64 simultaneous operations 2024-03-15 13:46:35 +02:00
Bananymous 48ea9e1c1d Kernel: PS2Controller uses RecursiveSpinLock so timeouts don't panic 2024-03-15 13:45:44 +02:00
Bananymous 42469b83fe Kernel: kernel panic is now sent to all processors 2024-03-15 13:45:01 +02:00
Bananymous e65bc040af Kernel: Now all active processors are used in scheduling 
When a timer reschedule happens, ipi is broadcasted too all
processors for them to perform a reschedule!

Bananymous 45d6caa1d0 Kernel: APs now start their idle threads when scheduler is started 2024-03-09 23:51:40 +02:00
Bananymous 55d2a64f54 Kernel: Map interrupt handlers for all processors 
This doesn't mean that processors will actually handle the irqs

Bananymous 2420886c2c Kernel: Move current and idle thread to Processor 2024-03-08 23:39:29 +02:00
Bananymous e636dce919 Kernel: Rewrite scheduler thread lists 
Scheduler now has its own data SchedulerQueue which holds active nad
blocking thread lists. This removes need for BAN/Errors.h and making
current thread separate element instead of iterator into linked list.
This makes it possible to have current_thread on each processor
instead of a global one in Scheduler.
