Indexed XF loads specify the number of 32-bit words (generally floats, but light data has some integers) to load, not the number of bytes. This was only a mistake in the fifo analyzer text; the actual implementation already loaded words.
The light LIT fifolog from https://bugs.dolphin-emu.org/issues/13635 has position data at physical address 11ae3180. This works fine when using the memory viewer in physical mode, but the corresponding virtual address (91ae3180) previously didn't show anything in effective mode. It works fine now though.
This shouldn't affect playback of fifologs as everything in there uses physical addresses; this only impacts the memory viewer.
This logic was copied from CBoot::SetupBAT.
This reverts the revert commit bc67fc97c3,
except for the changes in BaseConfigLoader.cpp, which caused the bug
that made us revert 72cf2bdb87. PR 12917
contains an improved change to BaseConfigLoader.cpp, which can be merged
(or rejected) independently.
A few changes have also been made based on review comments.
Found this bug while testing; if I manually edit the config files while Dolphin is closed I was able to get debug and hardcore on at the same time, this resolves that.
AchievementManager::SetHardcoreMode now handles the (non-Qt) settings disabled by hardcore mode, instead of doing this on the Qt layer. Also ensured Init/Enable Achievements paths run this code, fixing the bug wherein the player can manipulate things when achievements are disabled that persist when turned back on.
Dolphin has been using edge-to-edge rendering for a little while now,
but it has required a bit of manual work. Now that edge-to-edge is
becoming something expected of apps in Android 15, there's a nicer API
we can use.
Tested on Android 8, 11 and 13, with no changes in behavior noted.
So far, Dolphin hasn't been able to run on Android devices that use a
16 KiB page size. 16 KiB page sizes are a very new Android feature that
no phones have shipped with so far, so we're still compatible with the
phones that exist out there, but let's get this fixed before phones
start shipping with 16 KiB page sizes.
Because I couldn't get Android Studio's emulator to work, I haven't been
able to confirm that this change actually makes Dolphin fully compatible
with devices that use a 16 KiB page size. But I have confirmed that this
doesn't break anything on a regular 4 KiB page size device.
Prevent potential issues when creating the Graphics window (and thus
calling PopulateBackendInfo) while the core state is Stopping, like we
already do while it's Starting or Running.
Remove the PopulateBackendInfoFromUI function, which had a single caller
(GraphicsWindow::OnBackendChanged) and checked that the core wasn't
running or starting before calling PopulateBackendInfo.
Move the core state check into PopulateBackendInfo and have
OnBackendChanged call that instead. This guarantees the check is
performed by all callers of PopulateBackendInfo, preventing
potential reintroduction of the crash fixed in 3d4ae63f if another call
to PopulateBackendInfo is added.
As of the previous commit the only other caller of PopulateBackendInfo
is Core::Init shortly before s_state is set to Starting, so it will
always pass the check and so maintain its current behavior.
Remove the second of two calls to PopulateBackendInfo during emulation
startup. This call was originally the only one, but b214e0e added an
earlier call to handle the backend being changed by the GameINI.
The PR discussion doesn't explain why the original call was left in; I
suspect it was just overlooked.
As a bonus, this removes one of the extra copies of the "Video Info" On
Screen Display message at startup when using OpenGL.
Fix a crash when opening the Graphics window for the first time during
emulation startup when the backend is Vulkan, D3D11, or D3D12.
Don't call PopulateBackendInfo() from the Host thread when the core is
starting up. First, the function has already been called in Core::Init()
so we don't need to again. More importantly, PopulateBackendInfo() calls
g_video_backend->InitBackendInfo(), and the Vulkan and D3D
implementations of those functions load and then unload libraries (and
their associated function pointers) which are potentially in use by
other threads.
This crash was reliably reproducible with the following steps:
1) Select an affected backend.
2) Enable "Compile Shaders Before Starting"
3) Delete the cached shaders (but not the .uidcache file) for the game
you're testing.
4) Close and reopen Dolphin.
5) Start the game.
6) While the game is still booting or compiling shaders, open the
Graphics window for the first time in that Dolphin session.

Before, Dolphin would randomly crash when updating the cheat search when automatic refresh was enabled. (Having a large number of addresses listed, e.g. by starting with an "any value" search, may contribute). The crash was due to QTableWidget::item returning nullptr in RefreshGUICurrentValues, presumably due to the table being resized on the UI thread while the emulated CPU thread was updating the values. I've fixed this by pausing the CPU thread for the entirety of OnNextScanClicked; this eliminated crashes in my testing.
With 12 uses of `JoinStrings` in the codebase vs 36 uses of `fmt::join`, fmtlib's range adapter for string concatenation with delimiters is clearly the preferred option.
Migrating `Common::CaseInsensitiveLess` to StringUtil.h will hopefully discourage rolling one's own solution in the future for case-insensitive associative containers when this (quite robust!) solution already exists.
`Common::CaseInsensitiveStringCompare::IsEqual` was removed in favor of using the `Common::CaseInsensitiveEquals` function.
The `a.size() != b.size()` condition in `Common::CaseInsensitiveEquals` can be removed, since `std::ranges::equal` already checks this condition (confirmed in libc++).
There were three distinct mechanisms for signaling breakpoint changes in DolphinQt, and the wiring had room for improvement. The behavior of these signals has been consolidated into the new `Host::PPCBreakpointsChanged` signal, which can be emitted from anywhere in DolphinQt to properly update breakpoints everywhere in DolphinQt.
This improves a few things:
- For the `CodeViewWidget` and `MemoryViewWidget`, signals no longer need to propagate through the `CodeWidget` and `MemoryWidget` (respectively) to reach their destination (incoming or outgoing).
- For the `BreakpointWidget`, by self-triggering from its own signal, it no longer must manually call `Update()` after all of the emission sites.
- For the `BranchWatchDialog`, it now has one less thing it must go through the `CodeWidget` for, which is a plus.
If texture dumping is enabled, notify the user on emulation startup
using an On Screen Display message.
Also notify the user when texture dumping is toggled.

The low-pass and biquad filters run in set40 mode where accessing ac#.m
returns the value of ac#.hm clamped to 16 bits.
This fixes the crackling in "Need for Speed: Nitro" (issue 13610).
Also make the lower bound match hardware (-0x8000 instead of -0x7FFF).
During 25-bit rounding, subnormals are "normalized"
This would normally mean that the exponent needs to be able to be <-1023
Instead, you can modify at what bit you round and get the same results!
This is done by finding the highest bit and shifting right the round bit

Changes integer rounding to more closely meet the documentation
The documentation explains to round before doing any bounds checks
All this really does is make sure some exception bits won't be set wrong
This depends on the rounding mode, fixing cases such as:
- Round to even, (0x7fffffff, 0x7fffffff.8)
- Round to down, (0x7fffffff, 0x80000000)
This change also uses some standard functions for rounding
Previously using them was casting to an s32 directly, now keeps the f64
RoundToIntegerMode introduced due to roundeven not being part of C++17
Finally, it can change a >0x7fffffff to >=0x80000000, done because:
- It looks nicer now with integers (I liked 0s)
- It gives ever so slightly better codegen on Aarch64

I wasn't aware that even with a size of zero, it's still not safe to pass a nullptr to `std::memcpy`. When `CachedInterpreterEmitter::PoisonCallback` is written, UB is happening.
Invert conditions, invert decrement checks, and make conditional branches unconditional. USnapshotMetadata in prior versions of Dolphin is forward-compatible with these changes (tested on x86_64).
Objects which get parented automatically by later processing now pass a nullptr to the constructor to make the intent clearer. Also fixed "true" and "false" not being translatable strings.
This is a minor improvement to add line numbers to the LOG_VULKAN_ERROR
define. Basically error logs for Vulkan will now look like:
```
// This
25:03:347 VideoBackends/Vulkan/VulkanLoader.cpp:247 E[Video]: (WaitForCommandBufferCompletion:278) vkWaitForFences failed: (2: VK_TIMEOUT)
// Instead of
15:45:154 VideoBackends/Vulkan/VulkanLoader.cpp:247 E[Video]: (WaitForCommandBufferCompletion) vkWaitForFences failed: (2: VK_TIMEOUT)
```
Set the Render Window as the parent of the Confirm On Stop confirmation
dialog when Keep Window On Top is enabled, ensuring it will always be
visible.
Previously, when Confirm On Stop and Keep Window On Top were both
enabled the Confirm On Stop dialog could be hidden by the render window
in the following situations:
* Clicking Stop in the Main Window
* Clicking the Main Window's close button
* Pressing the Stop hotkey while in FullScreen mode
This was particularly troublesome because the confirm dialog is modal,
preventing the user from moving the render window out of the way if it
was obscuring the dialog.
Fixes https://bugs.dolphin-emu.org/issues/13247.
A vector of length 0 can have a null data pointer, which causes UB when
passed to memcpy, so only copy when we actually have data to copy. This
caused crashes in certain cases when compiling Dolphin with Clang and
LTO enabled.
Allow connecting or disconnecting multiple Wii Remotes simultaneously
instead of only handling the highest index whose hotkey is pressed. This
allows using a single hotkey to toggle multiple remotes.
Before the call to OnSelectionChange, m_code_edit and m_code_remove are
disabled and UpdateList calls m_code_list->clear(), thereby deselecting
any selected items.
When no items are selected, OnSelectionChange disables m_code_edit and
m_code_remove and then returns. Since that was already done, the call
doesn't change anything and can be removed.
Create ARCodeWidget and GeckoCodeWidget once on startup rather than
every time a game is launched or shutdown.
In addition to losing focus on the tab (since the previous widget and
tab no longer existed), the behavior prior to this commit could cause a
crash if the user initiated a game shutdown and then opened a code edit
window since the AR/GeckoCodeWidget would get deleted in the meantime.
Also some minor refactoring of nearby/related code:
* Make non-obvious variable types explicit instead of auto.
* Throw some consts around.
* Use setDisabled(empty) instead of setEnabled(!empty).
Changes the RetroAchievements "Log In" button's text to "To log in, stop the current emulation." when the button is disabled because an emulation session is active. This allows a user to understand why the button is disabled, and how this state can be resolved.
Previously, it could be unclear why this button was disabled without an understanding of the underlying system.

The description of the Speed Limit setting currently uses a lot of
complicated terms, like "emulated time" (known to many Dolphin
developers, but in my experience not known by even advanced emulator
users) and "maximum time scale" (I have never heard it before). The
meaning of "sustainable" is also unclear in context.
This commit rewords the description to be easier to understand.
Fixes https://bugs.dolphin-emu.org/issues/13593. Before, it would attempt to
use the old shader, which did not exist for the new stereo mode. Changing the
postprocessing shader afterwards would work properly, although passive 3D only
has one option, so it was just broken without restarting Dolphin.
This also fixes the UI not updating when using one of the stereo toggle hotkeys.
These patches were added in bde9a459cd
and enabled by default in 36ecfdd6b5.
They allowed the game to run in Dolphin but disabled dynamic shadows.
The game adds 4 to the start address of otherwise valid display lists
for no obvious reason. Now that Dolphin forces 32-byte alignment these
patches are no longer needed.
Input/output tracking is intended to speed up incremental builds by
skipping a target when it doesn't need to be built. However, this seems
to be unreliable for UnitTests' AfterBuild target. Let's remove it.
It's still the case that UnitTests' AfterBuild target will be skipped if
UnitTests doesn't need to be rebuilt. (Note that UnitTests always needs
to be rebuilt if SCMRevGen changed.)
I haven't seen these problems with DolphinQt's rather similar
input/output tracking. This may be because DolphinQt's one also has the
exe file as an input/output.
`std::bit_cast` participates in overload resolution only if `sizeof(To) == sizeof(From)` and both `To` and `From` are *TriviallyCopyable* types, so the static assertions here can be removed. `[[nodiscard]]` was added as well.
Like the previous commit, but for UnitTests. This time all operating
systems were affected.
I also made UnitTests.vcxproj use the same way of copying as
DolphinQt.vcxproj, just for consistency.
For a long time now, we've had a problem where game INIs persist in
the copied Sys folder if they've been deleted from the original Sys
folder. (I still have hundreds of game INIs locally that only set
EmulationStateId, and we removed those game INIs 6 years ago. On the
buildbot, we do occasionally clear out the build directories manually,
so I'd assume it's not quite as bad there.)
This commit fixes the problem by deleting the output Sys folder before
copying the original Sys folder to the output Sys folder. This should be
a bit slower, but in my testing, the difference seems small. At least if
you have an SSD, which I really hope people have nowadays!
Operating systems other than Windows have not been touched, because:
* Android: Already explicitly deletes the output Sys folder.
* macOS: Does some magic to put the Sys folder in the app bundle, which I
will simply assume isn't affected by this problem, without testing.
* Linux: Expects the person building to manually manage the Sys folder.
