Merge pull request #894 from lioncash/object 
kernel: Move object class to its own source files
 7 years ago
Lioncash 6058c84b79 kernel/thread: Make GetFreeThreadLocalSlot()'s loop indices size_t 
Avoids using a u32 to compare against a range of size_t, which can be a
source of warnings. While we're at it, compress a std::tie into a
structured binding.

Lioncash fac0e42b2f kernel/thread: Make GetFreeThreadLocalSlot() reference parameter a const reference 
This function only reads the data being referenced, it doesn't modify
it, so we can turn the reference into a const reference.

Lioncash 9a50a4f2cc kernel/thread: Make GetFreeThreadLocalSlot() internally linked 
This function isn't used outside of this translation unit, so we can
make it internally linked.

Lioncash bf45092c61 kernel: Move object class to its own source files 
General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.

Lioncash a2304fad16 kernel: Remove unnecessary includes 
Removes unnecessary direct dependencies in some headers and also gets
rid of indirect dependencies that were being relied on to be included.

Merge pull request #751 from Subv/tpidr_el0 
CPU: Save and restore the TPIDR_EL0 system register on every context switch
 7 years ago
Subv d84eb9dac6 CPU: Save and restore the TPIDR_EL0 system register on every context switch. 
Note that there's currently a dynarmic bug preventing this register from being written.

Lioncash dbfe82773d thread: Convert ThreadStatus into an enum class 
Makes the thread status strongly typed, so implicit conversions can't
happen. It also makes it easier to catch mistakes at compile time.

Merge pull request #690 from lioncash/move 
core/memory, core/hle/kernel: Use std::move where applicable
 7 years ago
Lioncash 46458e7284 core/memory, core/hle/kernel: Use std::move where applicable 
Avoids pointless copies

Lioncash 3a4841e403 core: Don't construct instance of Core::System, just to access its live instance 
This would result in a lot of allocations and related object
construction, just to toss it all away immediately after the call.

These are definitely not intentional, and it was intended that all of
these should have been accessing the static function GetInstance()
through the name itself, not constructed instances.

Michael Scire 9d71ce88ce Kernel/Arbiters: Implement WaitForAddress 7 years ago
Subv 9cd87a6352 Kernel/Threads: A thread waking up by timeout from a WaitProcessWideKey may already have an assigned lock owner. 
This situation may happen like so:
Thread 1 with low priority calls WaitProcessWideKey with timeout.
Thread 2 with high priority calls WaitProcessWideKey without timeout.
Thread 3 calls SignalProcessWideKey
- Thread 2 acquires the lock and awakens.
- Thread 1 can't acquire the lock and is put to sleep with the lock owner being Thread 2.
Thread 1's timeout expires, with the lock owner still being set to Thread 2.

core_timing: Namespace all functions and constants in core_timing's header 
All of these variables and functions are related to timings and should be within the namespace.

Subv 46572d027d Kernel: Implemented mutex priority inheritance. 
Verified with a hwtest and implemented based on reverse engineering.

Thread A's priority will get bumped to the highest priority among all the threads that are waiting for a mutex that A holds.
Once A releases the mutex and ownership is transferred to B, A's priority will return to normal and B's priority will be bumped.

Subv 5fdfbfe25a Kernel: Remove old and unused Mutex code. 7 years ago
Subv e81a2080eb Kernel: Corrected the implementation of svcArbitrateLock and svcArbitrateUnlock. 
Switch mutexes are no longer kernel objects, they are managed in userland and only use the kernel to handle the contention case.
Mutex addresses store a special flag value (0x40000000) to notify the guest code that there are still some threads waiting for the mutex to be released. This flag is updated when a thread calls ArbitrateUnlock.

TODO:
* Fix svcWaitProcessWideKey
* Fix svcSignalProcessWideKey
* Remove the Mutex class.

Subv 94ee8fc97b Kernel/IPC: Add a small delay after each SyncRequest to prevent thread starvation. 
Ported from citra PR #3091

The delay specified here is from a Nintendo 3DS, and should be measured in a Nintendo Switch.

This change is enough to prevent Puyo Puyo Tetris's main thread starvation.
