This works around Linux drivers for DS4 (Playstation 4) controllers splitting the device into three separate event nodes which makes configuration difficult.
To prevent collisions of input names in combined devices more descriptive names are now used when possible.
Due to the way the ModRM encoding works on x86, memory addressing
combinations involving RBP or R13 need an additional byte for an 8-bit
displacement of zero.
However, this was also applied in cases where it is unnecessary,
effectively wasting a byte.
- MatR with RSP or R12
8B 44 24 00 mov eax,dword ptr [rsp]
8B 04 24 mov eax,dword ptr [rsp]
- MRegSum with base != RBP or R13
46 8D 7C 37 00 lea r15d,[rdi+r14]
46 8D 3C 37 lea r15d,[rdi+r14]
- MComplex without offset
8B 4C CA 00 mov ecx,dword ptr [rdx+rcx*8]
8B 0C CA mov ecx,dword ptr [rdx+rcx*8]
Test the behavior of OpArg::WriteRest by using MOV with the various
addressing modes (MatR, MRegSum, etc.) in the source operand.
Both the instruction and the instruction length are validated.
This updates the lint script to require clang-format 9 and reformats
existing source code. Since VS2019 ships with clang-format 9 this
should make auto reformats less painful.
This also updates the clang-format configuration to set
BraceWrapping.AfterCaseLabel to true to ensure consistent brace
style; otherwise clang-format 9+ defaults to putting braces on
the same line as switch case labels.
Was checking over this old code, and saw a comment calling me out for a lack of documentation.
It might be half a decade late, but better late then never.
The old logic would always emit LEA when both sources are in a register
and OE is disabled. However, ADD is still preferable when one of the
sources matches the destination.
Before:
45 8D 6C 35 00 lea r13d,[r13+rsi]
After:
44 03 EE add r13d,esi
The ES sysmodule in IOS62 (v6430) has an exception for the
Wii U Transfer Tool in the SetUid function.
If the active title is the Wii U Transfer Tool, then calling SetUid
is always allowed. (The UID is still checked first, though.)
Fixes https://bugs.dolphin-emu.org/issues/10985
Partitions are Wii-exclusive, and don't happen at the DVDInterface level in
IOS. This isn't quite the cleanest fix, but it gets rid of the assumption that
a partition is open on starting the game at least.
The various ioctls sometimes have different arguments than the DI command
registers, though they generally overlap. There are also a bunch of ioctls
that don't even normally go into DVDInterface, just returning various data.
Some of the implemented ioctls are new to Dolphin.
