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.

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.

Bananymous 054b41383f Kernel: Implement SpinLock unsafe that does not keep track of locker 
This will be used in scheduler where thread ids are changing

Bananymous 40b626b0aa Kernel: Rewrite all kernel mutexes 
Now SpinLock is actually just a spin lock and I added a Mutex that
does the same as the old "SpinLock". This is in preparation for
starting to support smp and making the kernel smp safe. This commit
also removes obsolete PageTableScope and CriticalScope which should
now be used by alternative APIs.

Bananymous f73e954b28 Kernel: Remove SpinLock from Pipe 
Pipe already is using lock on the inode. If you read from pipe when
there was no data, pipe blocked indefinately since writes were blocked
by Inode::m_lock.
