This packet is only used by the host to detect desyncs, and we don't really need to know the exact frame we desynced on (unless you're debugging, but you can just recompile for that), so it's perfectly fine to just send it less often. This makes it so the timebase packet is sent only every 60 frames, rather than every frame, which further cuts back on unnecessary bandwidth consumption.
PowerPCState's cr_val member is an array of u64s, so we can just use the
correct printf macro specifier within cinttypes. This also avoids
truncation on operating systems that use an LLP64 data model (like
Windows), where long is actually 32 bits in size, not 64-bit, which
could result in wonky values being printed, should Trace ever be used on
it.
define how many frames constitute a high or a low swing/shake when the
button is down. Also configurable is the number of frames to execute
the swing/shake after the button is released.
Previously there was only one function under the NetPlay namespace,
which is kind of silly considering we have all of these other types
and functions existing outside of the namespace.
This moves the rest of them into the namespace.
This gets some general names, like Player, for example, out of the global namespace.
Now the detection heuristic has changed, the old value is no longer
valid.
Some example thresholds for known mipmap effects that should trigger:
SMG's lava has a mimimum difference of ~17.8, SMG2's clouds have a
minimum difference of ~14.8, and Wind Waker's foam has a minimum
difference of ~15
Non-triggering examples were tested and all had a calculated difference
lower than 3.
So a value of 14 should lean towards false-negatives instead of
positives, but this is clearly incomplete testing and may require
further tweaks later.
Normally, SI is polled at a rate defined by the game, and we have to send the pad state to other clients on every poll or else we'll desync. This can result in fairly high bandwidth usage, especially with multiple controllers, mostly due to UDP/IP overhead.
This change introduces an option to reduce the SI poll rate to once per frame, which may introduce up to one frame of additional latency, but will reduce bandwidth usage substantially, which is useful for users on very slow internet connections.
Polling SI less frequently than the game asked for did not seem to cause any problems in my testing, so this should be perfectly safe to do.
Given we now use a base class for the interface, we can make all member
functions, types and constants that aren't directly related to
instructions private.
HID2.LSQE is the Load/store quantize enable bit for non-indexed format
instructions (which are psq_l, psq_lu, psq_st, and psq_stu). If this bit
is not set and any of these instructions are attempted to be executed,
then a program exception is supposed to occur.
This register is defined as "optional reserved" within the aarch64 ABI.
Linux doesn't use it, but we must not modify it on ios or windows.
As we have plenty of registers on aarch64, let's just always skip this one.
This function was duplicated across all the opcode tables: the main info
tables, the interpreter tables, and the x86-64 JIT tables. However, we
can just make the type of the std::array parameter a template type and
get rid of this duplication.
const on a parameter being passed by value in a prototype doesn't actually signify
anything, these are only applicable in the definition, where they make
the opcode parameter immutable.
inline has external linkage, which doesn't really make sense here, given
the function is only used within this translation unit. So we can
replace inline with static.
While we're at it, the code within the function can also be compressed
to a single return statement.
