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.

Bananymous 418bc54f2b Kernel: Move SpinLock definition to header and fix Scheduler locking
This patch allows inlining of spinlocks :)

Bananymous 9c36d7c338 BAN/Kernel: Rework assertion/panic system
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.

Bananymous efd8203232 BAN: Atomic memory order can be set per function call 2024-03-03 01:41:46 +02:00
Bananymous a667d88f93 Kernel: Remove now obsolete CriticalScope
All critical scopes in kernel are now replaced by SpinLocks. This
allows proper locking in actual multiprocessing with multiple cores.
