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 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 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.

BAN/Assert.h does not need any includes meaning it can be included
anywhere without problems.

Bananymous 8141b9977d Kernel: Per processor information is now stored in class Processor
This allows us to allocate processor stacks, and other per processor
structures dynamically in runtime. Giving processor stack to
ap_trampoline feels super hacky, but it works for now.

Bananymous c035d3c82c Kernel: Start all processors on kernel boot
Processors don't do anything, except print hello message and halt.
2024-03-03 02:19:43 +02:00
Bananymous 1de9daa40f Kernel: Move interrupt status stuff to Processor.h
SpinLocks are now locked with processor id instead of thread id. This
allows having multiple processors running while scheduler is not yet
activated.
