The earlier code always tried to use TitleDatabase for getting
title names, but that didn't work for disc-based games, because
there was no way to get the maker ID.
Unlike VEN, the endpoint is determined by the value at 8-12.
If it's non-zero, HID submits the request to the interrupt OUT
endpoint. Otherwise, the request is submitted to the IN endpoint.
This commit changes HIDv5 to keep track of endpoints (like IOS does)
and use them when submitting interrupt transfers.
This implements /dev/usb/hid v5, found in IOS57, IOS58 and IOS59.
This is an initial implementation that ignores some differences
with VEN because I lack understanding of what IOS is actually doing
sometimes. These are documented on the WiiBrew article:
https://wiibrew.org/wiki//dev/usb/hid_(v5)
One major difference that this implementation handles is about IDs.
It turns out Nintendo has decided to include the interface number in
the top byte of HIDv5 device IDs, unlike VEN -- even though everything
else about ioctl 1 is otherwise the same!
USBv5 IOS resource managers share most of their code. Some ioctls
are even completely the same! So let's separate the common code
from the VEN specific stuff to make HIDv5 easier to implement.
The descriptor copy code is not actually the same in HIDv4 and VEN,
so it did not make a lot of sense to put it in USB/Common.cpp.
Separate and move it to HIDv4 and VEN.
This cleanup is important because there are even more differences
between HIDv4 and HIDv5.
Fix the device ID struct to reflect the actual structure used by IOS.
It turns out that offset 2 is the internal device index. The reason
that field seemed to be "0x1e - interface_number" is that IOS only
keeps track of 32 devices and always looks for free entries from
the end of the internal array. With each USB interface being exposed
as a separate USBv5 device, "0x1e - interface_number" was mostly
correct... but wrong!
We also made the assumption that the interface number can be
identified from just a USBV5 device ID, which is definitely not true.
VEN (and HID) keep track of the interface number in the internal struct
instead of "reconstructing" it from the device ID (which is normally
not possible if we were generating IDs correctly)
This commit fixes all of these inaccuracies.
Some lines of code in Dolphin just plainly grabbed the value of
g_ActiveConfig.iEFBScale, which resulted in Auto being treated as
0x rather than the actual automatically selected scale.
This reverts commit 1fc910b3ea9eafcc3cc5132bdfc51731ba5fa9fd,
replacing the old INI setting EFBScale with a new INI setting
called InternalResolution, which has a simpler mapping:
| EFBScale | InternalResolution
----------------- | -------------------- | --------------------
Auto (fractional) | 0 |
Auto (integral) | 1 | 0
1x | 2 | 1
1.5x | 3 |
2x | 4 | 2
2.5x | 5 |
3x | 6 | 3
4x | 7 | 4
5x | 8 | 5
6x | 9 | 6
All the fractional IRs were removed in f090a943.
It is not possible to tell whether DLC contents are supposed to be
present on the NAND or not, because they're treated as "optional".
So this commit changes the NAND check to not consider missing
contents for DLC titles as an issue.
"N/A" can be awkward to handle in translations.
I don't think there's much point in showing "N/A" rather than
leaving the description box blank, so let's just leave it blank.
Use std::string(cstring, strnlen(cstring, max_length)) instead of
trying to remove extra null characters manually, which is a bit
ugly and error prone.
And indeed, the original code contained a bug which would cause
extra NULLs to not be removed at all if the string did not
end with a NULL -- causing issues down the road when constructing
paths for sub-entries.
Because the Wii NAND size is finite, mark titles that were installed
only for booting as temporary, and remove them whenever we need to
install another title (to make room). This is exactly what the
System Menu does for temporary SD card title data.
