svc: Log parameters in SetMemoryAttribute()
2018-07-24svc: Resolve sign comparison warnings in WaitSynchronization()Lioncash
The loop's induction variable was signed, but we were comparing against an unsigned variable.
2018-07-24svc: Log parameters in SetMemoryAttribute()Lioncash
Provides slightly more context than only logging out the address value.
2018-07-22Kernel/SVC: Perform atomic accesses in SignalProcessWideKey as per the real ↵Subv
kernel.
2018-07-19thread: Convert ThreadStatus into an enum classLioncash
Makes the thread status strongly typed, so implicit conversions can't happen. It also makes it easier to catch mistakes at compile time.
2018-07-19svc: Correct always true assertion case in SetThreadCoreMaskLioncash
The reason this would never be true is that ideal_processor is a u8 and THREADPROCESSORID_DEFAULT is an s32. In this case, it boils down to how arithmetic conversions are performed before performing the comparison. If an unsigned value has a lesser conversion rank (aka smaller size) than the signed type being compared, then the unsigned value is promoted to the signed value (i.e. u8 -> s32 happens before the comparison). No sign-extension occurs here either. An alternative phrasing: Say we have a variable named core and it's given a value of -2. u8 core = -2; This becomes 254 due to the lack of sign. During integral promotion to the signed type, this still remains as 254, and therefore the condition will always be true, because no matter what value the u8 is given it will never be -2 in terms of 32 bits. Now, if one type was a s32 and one was a u32, this would be entirely different, since they have the same bit width (and the signed type would be converted to unsigned instead of the other way around) but would still have its representation preserved in terms of bits, allowing the comparison to be false in some cases, as opposed to being true all the time. --- We also get rid of two signed/unsigned comparison warnings while we're at it.

2018-05-02general: Make formatting of logged hex values more straightforwardLioncash
This makes the formatting expectations more obvious (e.g. any zero padding specified is padding that's entirely dedicated to the value being printed, not any pretty-printing that also gets tacked on).
2018-04-29string_util: Remove StringFromFormat() and related functionsLioncash
Given we utilize fmt, we don't need to provide our own functions for formatting anymore

2018-04-23Merge pull request #370 from Subv/sync_primitivesbunnei
Kernel: Reworked the new kernel synchronization primitives.
2018-04-23Kernel: Implemented mutex priority inheritance.Subv
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.
2018-04-20Kernel: Remove unused ConditionVariable class.Subv
2018-04-20Kernel: Properly implemented svcWaitProcessWideKey and svcSignalProcessWideKeySubv
They work in tandem with guest code to provide synchronization primitives along with svcArbitrateLock/Unlock
2018-04-20Kernel: Corrected the implementation of svcArbitrateLock and svcArbitrateUnlock.Subv
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.
2018-04-20resource_limit: Make ResourceTypes an enum classLioncash
