This prevents the IOS crypto code and keys from being spread over
the codebase. Things only have to be implemented once, and can be
used everywhere from the IOS code.
Additionally, since ES exposes some IOSC calls directly (DeleteObject
and Encrypt/Decrypt), we need this for proper emulation.
Currently, this only supports AES key objects.
As the name is immediately stored into a class member, a move here is a
better choice.
This also moves the constructor implementations into the cpp file to
avoid an otherwise unnecessary inclusion in the header. This is also
likely a better choice as Section contains several non-trivial members,
so this would avoid potentially inlining a bunch of setup and teardown
code related to them as a side-benefit.
If the delimiters of a memory aren't exactly the same as an address, but their size includes the memory breakpoint delimiter, the break will not go through. This makes it so that you can specify a search for a memory breakpoint with a data size and will check if the data fits with that size on all memory breakpoints so the breaks go through.
This is slightly safer than writing contents to /title directly.
We still cannot rename everything in one go atomically, but this allows
implementing AddTitleCancel very easily.
Also, this ensures that when a title import fails, no incomplete files
will be left in the title directory, which can mess up the system menu.
Regression introduced in e99cd57 / 4935: VideoBackends: Set the maximum
range when the depth range is oversized[1]. The NV_depth_buffer_float
extension is not part of OpenGL 3.0, and requiring it causes a hard
crash when it's not supported (e.g. macOS).

This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
Getting and setting configuration from the base config layer are common
and repetitive tasks. This commit adds some simpler to use functions to
make the new system easier to work with.
Config::Get and Config::Set are intended to make switching from
SConfig a bit less painful. They always operate on the main system.
Example usage:
// before
auto base_layer = Config::GetLayer(Config::LayerType::Base);
auto core = base_layer->GetOrCreateSection(Config::System::Main, "Core");
u8 language;
core->Get("Language", &language, 0);
SetData("IPL.LNG", language);
// now
auto base_layer = Config::GetLayer(Config::LayerType::Base);
auto core = base_layer->GetOrCreateSection(Config::System::Main, "Core");
SetData("IPL.LNG", core->Get<u8>("Language", 0));
// or simply
SetData("IPL.LNG", Config::Get<u8>("Core", "Language", 0));
Given a std::map can't have duplicate keys, iterating over the map
explicitly isn't necessary, and find() can just be used instead.
Also, instead of manually calling push_back() for every entry to
be added, the range constructor of std::vector can be used instead to add
the whole range all at once.
We (the Microsoft C++ team) use the dolphin project as part of our "Real world code" tests.
I noticed a few issues in windows specific code when building dolphin with the MSVC compiler
in its conformance mode (/permissive-). For more information on /permissive- see our blog
https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/.
These changes are to address 3 different types of issues:
1) Use of qualified names in member declarations
struct A {
void A::f() { } // error C4596: illegal qualified name in member declaration
// remove redundant 'A::' to fix
};
2) Binding a non-const reference to a temporary
struct S{};
// If arg is in 'in' parameter, then it should be made const.
void func(S& arg){}
int main() {
//error C2664: 'void func(S &)': cannot convert argument 1 from 'S' to 'S &'
//note: A non-const reference may only be bound to an lvalue
func( S() );
//Work around this by creating a local, and using it to call the function
S s;
func( s );
}
3) Add missing #include <intrin.h>
Because of the workaround you are using in the code you will need to include
this. This is because of changes in the libraries and not /permissive-
The built-in `configure_file` command correctly handles the case where
none of the variables change and scmrev.h doesn't need to be rebuilt.
This saves a full re-link of Dolphin any time CMake is re-run.
This reimplements the USB HID v4 IOS device using the new common
USB code (to reuse more code and allow emulated HIDs to be added
more easily in the future).
The main difference is that HIDs now have to be whitelisted, like
every other USB device for OH0 and VEN.
libusb on Windows is limited to only a single context. Trying to open
more than one can cause device enumerations to fail randomly.
libusb is thread-safe and we don't use the manual polling support (with
`poll()`) so this should be safe.
Some structures will be reused and shared between several IOS USB
device implementations. This prepares for the upcoming USB PR.
I've also removed GetPointer calls in the trivial case (BT passthrough)
Without this, attempts to savestate std::set will fail with an error
about dropping the const qualifier.
<Lioncash> leoetlino: I'll try to break it down: So, when you do a
ranged-for on a container, it's essentially syntactic sugar over begin
and end iterators. std::set is an associative container where the key
type is the same as the value type, and so it's required that all
iterator functions return constant iterators. If this wasn't a
requirement, it would allow changing the ordering of elements from
outside of the set's API (this is bad).
This attempts to make some bit arithmetic more self-documenting and also
make it easier during review to identify potential off-by-one errors by
making it possible to just specify which bits are being extracted.
Functions both support the case where bits being extracted can vary and
fixed bit extraction. In the case the bits are fixed, compile-time asserts
are present to prevent accidental API usage at compile-time.
e.g. Instead of shifting and masking to get bits 10 to 15,
Common::ExtractBits<10, 15>(value) can just be done instead.
Dolphin is able to generate one with all correct default settings, so
we don't need to ship with a pre-generated SYSCONF and worry about
syncing default settings.
Additionally, this commit changes SysConf to work with session SYSCONFs
so that Dolphin is able to generate a default one even for Movie/TAS.
Which SYSCONF needs to be touched is explicitly specified to avoid
confusion about which file SysConf is managing.
(Another notable change is that the Wii root functions are moved into
Core to prevent Common from depending on Core.)
Size is internally stored as a size_t, so having an int parameter
would cause implicit sign-conversion from a signed value to an
unsigned value to occur.
Jan 04 22:55:01 <leoetlino> fwiw, it looks like there are new warnings in the RegCache code
Jan 04 22:55:04 <leoetlino> Source/Core/Core/PowerPC/Jit64/FPURegCache.cpp:13:33: warning: declaration shadows a variable in the global namespace [-Wshadow]
Jan 04 22:56:19 <@Lioncash> yeah, the jit global should have a g_ prefix.
This fixes shadowing warnings and adds the g_ prefix to a global.
Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.
This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.
As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.
'operator void*' is basically a pre-C++11-ism that was used, as C++03
only had the notion of implicit type-conversion operators, but not explicit type
conversion operators (allowing implicit conversion of a file handle to
bool can go downhill pretty quickly).
Windows-1252 was sometimes being referred to as ASCII or ANSI
in Dolphin, which is incorrect. ASCII is only a subset of
Windows-1252, and ANSI is (rather improperly) used in Windows
to refer to the current code page (which often is 1252 on
Western systems, but can also be something entirely different).
The commit also replaces "SJIS" with "Shift JIS". "SJIS"
isn't misleading, but "Shift JIS" is more commonly used.
Prevents path traversal without needing an absolute path
function, and also improves accuracy (character sequences
like ../ appear to have no special meaning in IOS).
This removes the creation and usage of /sys/replace,
because the new escapes are too complicated to all
be representable in its format and because no other
NAND handling software seems to use /sys/replace.
This reverts commit 141f3bfb3a.
The implementation of getting absolute paths wasn't working
on non-Windows systems, which is a huge problem for IOS HLE.
In the code view, it would never say r1 or r2, but rather sp (stack pointer) and rtoc (register of the table of content) respectively. In the register view, all it says is the register number. This is an inconvenience considering it might not be obvious which register belongs to which of these terms.
Also make r13 named the "sda" for small data area with the same convention as above.
This is done to remove confusions among potential debugger users and to also make it more accurately tell what this feature is actually doing. Despite being true that it is using a memcheck (and it certianly checks that memory), the idea being to break on a memory access isn't really obvious especially considering that memchecks are also used in full MMU emulation to handle exceptions. It also doesn't help that memchecks are now supported in every builds.
It also changes the corresponding log because this log would be wanted by the user which means it should be more obvious that it was caused by the "memory breakpoint".
Using cmake and GCC, logs would contain the full file path when logging making logs lines unnecessarily long. This is solved by just removing anything before "/Source/Core/" (where / is whatever your OS uses to separated directory).
This fixes an issue where the Bluetooth info section could be fully
filled up by syncing 5 Wiimotes in passthrough mode then switching to
emulated Bluetooth; emulated Wiimotes were then unable to be used.
The "real" SYSCONF section is now backed up before being replaced with
a blank section that the emulated BT adapter can always fill with 5
Wiimotes without issues.
This backup is restored by the passthrough code, instead of during
the Bluetooth mode switch because this should be done regardless of the
user interface, and even without UI (if the config file is edited
manually).
When standby mode is enabled, this causes games to ES_Launch the system
menu instead of directly asking IOS (the STM more precisely) to shut
down, which prevents graceful shutdown from working
(it'll appear to hang).
Dolphin never supported WC24 standby mode anyway, so this shouldn't
cause any issues. (This should be reverted if and when WC24 standby is
implemented…)
It was never used, even when the code tried to make sure it was initialised and passed correctly. This is a supplementary fix for the memCheck dialog as this option will now work correctly.
This changes GetSymbolFromName to not require the passed name to
completely match with the symbol name. Instead, we now match
against the stripped symbol name (i.e. only the function name).
This fixes a regression introduced by #4160, which prevented
HLE::PatchFunctions() from working properly.
It didn't really made sense to disable 2 logs levels in releases builds while the level LDEBUG should really be where logs that would impact performance be. Info should be logs that report potentially usefull information and debug should report info that would only be usefull in debug context as they are called very often. To make this work, a lot of info log would have to be made debug log.
It also avoid inaccurate logs level done due to not using debug builds. While searching through the code, I saw a ton of logs that should have been info log, likely done to avoid using a debug build (which shouldn't happen considering the level debug exists anyway).
The whole idea is to have more meaningful logs in release builds while maintaining minimal performance loss from choosing the highest level. This could potentially help to diagnose issues or to know more about what the emulator is actually doing.
The next commit aims to sort the log levels for this purpose.
clang-format really *wants* the two empty lines to be removed;
otherwise, it will always flag MemoryUtil as needing formatting changes
which is an annoyance when it is used as a git filter driver.
These are needed for the next commit. I had to modify the implementation of the DSP one too, but since it basically isn`t used, I don`t think it matters much. These options only matters when adding one.
Fundamentally, all this does is enforce the invariant that we always
translate effective addresses based on the current BAT registers and
page table before we do anything else with them.
This change can be logically divided into three parts. The first part is
creating a table to represent the current BAT state, and keeping it up to
date (PowerPC::IBATUpdated, PowerPC::DBATUpdated, etc.). This does
nothing by itself, but it's necessary for the other parts.
The second part (mostly in MMU.cpp) is simply removing all the hardcoded
checks for specific untranslated addresses, and consistently translating
addresses using the current BAT configuration. Very straightforward, but a
lot of code changes because we hardcoded assumptions all over the place.
The third part (mostly in Memmap.cpp) is making the fastmem arena reflect
the current BAT configuration. We do this by redoing the mapping (calling
memmap()) based on the BAT table whenever it changes.
One additional minor change is that translation can fail in two ways:
either the segment is a direct store segment, or page table lookup failed.
The difference doesn't usually matter, but the difference affects cache
instructions, like dcbz.
Replace adhoc linked list with a priority heap. Performance
characteristics are mostly the same, but is more cache friendly.
[Priority Queues have O(log n) push/pop compared to the linked
list's O(n) push/O(1) pop but the queue is not big enough for
that to matter, so linear is faster over linked. Very slight gains
when framelimit is unlimited (Wind Waker), 1900% -> 1950%]
memory check
Also fix an oddity in the case when the last memory check is deleted,
the jit cache was supposed to be cleared in that case, but it was out of
the for loop that finds the one to delete so it was never run.
Naturally, the same fix for the adding the first memory check was
applied.
This should help prevent breakage when the curl.h header is changed.
As far as I can tell this only increases the compile time by a hair, but prevents needing to create a PR every time curl.h gets updated. Alternatively I'm experimenting with CURL_STRICTER defined per a conversion with booto:
>booto | krakn: try having CURL_STRICTER defined for the build?
Credit goes to: flacs for the suggestion to include curl.h
Fix include
git diff --name-only already took care of only returning the name, so
the awk is unneeded and makes it return only empty file names.
Facepalm, I know. Sorry for this oversight.

Most modern Unix environments use 64-bit off_t by default: OpenBSD,
FreeBSD, OS X, and Linux libc implementations such as Musl.
glibc is the lone exception; it can default to 32 bits but this is
configurable by setting _FILE_OFFSET_BITS.
Avoiding the stat64()/fstat64() interfaces is desirable because they
are nonstandard and not implemented on many systems (including
OpenBSD and FreeBSD), and using 64 bits for stat()/fstat() is either
the default or trivial to set up.
CScript must be run as 64-bit regardless of the MSBuild bitness. Otherwise it won't find 64-bit Git installations.
However the "Sysnative" redirector is not available for 64-bit processes. So a fix is needed when 64-bit MSBuild is run.
The "ProgramFiles(x86)" Macro is only set for 64-bit, otherwise it is empty. Therefore it can be used as condition to check whether the current MSBuild process is 32 or 64-bit.
OS X uses a case insensitive filesystem by default: when I try to build,
a system header does #include <assert.h>, which picks up
Source/Core/Common/Assert.h. This only happens because CMakeLists adds
'${PROJECT_BINARY_DIR}/Source/Core/Common' as an include directory: in
an out-of-tree build, that directory contains no other source files, but
in an in-tree build PROJECT_BINARY_DIR is just the source root.
This is only used for scmrev.h. Change the include directory to
'${PROJECT_BINARY_DIR}/Source/Core' and the include to
"Common/scmrev.h", which is more consistent with normal headers anyway.
