From 9ef94c8292beda825fa76e05ad2e561c6d571c95 Mon Sep 17 00:00:00 2001 From: riperiperi Date: Tue, 11 Apr 2023 07:55:04 +0100 Subject: ARMeilleure: Move TPIDR_EL0 and TPIDRRO_EL0 to NativeContext (#4661) * ARMeilleure: Move TPIDR_EL0 and TPIDRRO_EL0 to NativeContext Some games access these system registers several tens of thousands of times in a second from many different threads. While this isn't really crippling, it is a lot of wasted time spent in a reverse pinvoke transition. Example games are Pokemon Scarlet/Violet and BOTW. These games have a lot of different potential bottlenecks so it's unlikely you will see a consistent improvement, but it definitely disappears from the cpu profile. * Remove unreachable code. * Add ulong conversion for offsets * Nit --- ARMeilleure/State/NativeContext.cs | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'ARMeilleure/State/NativeContext.cs') diff --git a/ARMeilleure/State/NativeContext.cs b/ARMeilleure/State/NativeContext.cs index 89e875d1..3189bdd8 100644 --- a/ARMeilleure/State/NativeContext.cs +++ b/ARMeilleure/State/NativeContext.cs @@ -13,6 +13,8 @@ namespace ARMeilleure.State public fixed ulong V[RegisterConsts.VecRegsCount * 2]; public fixed uint Flags[RegisterConsts.FlagsCount]; public fixed uint FpFlags[RegisterConsts.FpFlagsCount]; + public long TpidrEl0; + public long TpidrroEl0; public int Counter; public ulong DispatchAddress; public ulong ExclusiveAddress; @@ -168,6 +170,12 @@ namespace ARMeilleure.State } } + public long GetTpidrEl0() => GetStorage().TpidrEl0; + public void SetTpidrEl0(long value) => GetStorage().TpidrEl0 = value; + + public long GetTpidrroEl0() => GetStorage().TpidrroEl0; + public void SetTpidrroEl0(long value) => GetStorage().TpidrroEl0 = value; + public int GetCounter() => GetStorage().Counter; public void SetCounter(int value) => GetStorage().Counter = value; @@ -214,6 +222,16 @@ namespace ARMeilleure.State } } + public static int GetTpidrEl0Offset() + { + return StorageOffset(ref _dummyStorage, ref _dummyStorage.TpidrEl0); + } + + public static int GetTpidrroEl0Offset() + { + return StorageOffset(ref _dummyStorage, ref _dummyStorage.TpidrroEl0); + } + public static int GetCounterOffset() { return StorageOffset(ref _dummyStorage, ref _dummyStorage.Counter); -- cgit v1.2.3
