This allows setting the brightness of the home LED on Nintendo Switch Pro controllers, in the range 0.0 - 1.0.
This can be updated at runtime by setting the hint dynamically.
Fixes https://github.com/libsdl-org/SDL/issues/3787
SDL_events_need_periodic_poll() and SDL_events_need_polling() are intended to allow the event loop to update joysticks and/or sensors if needed, however those systems only update when the SDL_update_joysticks and/or SDL_update_sensors variables are true. This change brings the behavior of these functions in line with if work will actually need to be performed.
This change allows the hints for AUTO_UPDATE to influence the polling behavior of the event loop such that an app can choose to update joysticks/sensors itself and avoid the expense of constantly sleeping and waking the event loop. Additionally in makes these functions marginally faster in some situations by not searching the active events.
Hint callbacks are called before the actual value in the hint is changed, so the functions SDL_AutoUpdateJoysticksChanged and SDL_AutoUpdateSensorsChanged were not actually properly updating their respective variables in repsonse to their auto update hint changing.
Instead, we pull the new hint value out of the value passed into the callback and use that to update the variables. Assume true on a null value as that was the previous behavior and it matches with the default values of SDL_update_joysticks/SDL_update_sensors.
Events to handle controller touchpads and sensors were added to the library but not added in `SDL_GameControllerEventState()`. This change adds the missing events.
- CMD_CHARGE_STATE was checking the seqnum instead of the payload
- Off-by-one error in size validation for command payload
- Unused payload space was left uninitialized in output report
As discussed in PR review, there may be an off-chance that the index
returned doesn't match up with SDL's display indexing.
This change ensures that the indices match and adds a safety check for
off-screen windows.
With the introduction of this function, it is possible that for certain
monitor and window configurations, creating an SDL window will cause a
native crash.

In testing, the window would not find a valid screen if created
"hanging" off a primary display with a secondary display below it. In
checking why this was the case, the `display_centre` was being
calculated with a negative y origin, causing a final negative value
falling outside all display bounds:
```
SDL error log [debug]: display_centre.y = -1296 + 1296 / 2
SDL error log [debug]: Display rect 0: 0 0 2560 1440
SDL error log [debug]: Display rect 1: 2560 -625 1080 2560
SDL error log [debug]: Display rect 2: 0 1440 1728 1296
```
The method that was being used to find the current window using the frame
origin/size seems unreliable, so I have opted to replace it with with a
tried method (https://stackoverflow.com/a/40891902).
Initial testing shows that this works with non-standard DPI screens, but
further testing would be appreciated (cc @sezero / @misl6 from the
original PR thread).
We actually request CSD mode with xdg-decoration for borderless
windows, so we get what we wanted there and there's no point in going
into fallback paths.
The 5.1 versions didn't use the new algorithm, and making that new
algorithm work took so many permutes that it was significantly slower
than just using the scalar versions.
However, mono-to-stereo is an extremely common conversion, and it's
trivial to accelerate it with plain SSE, so that was added!
Currently, the SDL_WINDOWEVENT_RESIZED event is sent before the actual
window is resized (and various internal state, such as the desired
GL/Vulkan backbuffer size, are updated). This makes sense, as SDL will
discard a no-op resize, which would be the case if we had resized before
sending the event (indeed, there are existing hacks to prevent this).
However, this means that SDL_{GL,Vulkan}_GetDrawableSize() will still
use the old size in the SDL_WINDOWEVENT_RESIZED handler. In the case of
SDL_Renderer, this means the drawable size it uses will be wrong, and
the viewport will get "updated" to the old value.
This then results in bug #5899.
Pipewire 0.3.44 introduced PW_KEY_TARGET_OBJECT, which is to be used to specify target connection nodes for streams. This parameter takes either a node path (PW_KEY_NODE_NAME) or serial number (PW_KEY_OBJECT_SERIAL) to specify a target node. The former is used in this case since the path is already being retrieved and stored for other purposes.
The target_id parameter in pw_stream_connect() is now deprecated and should always be PW_ID_ANY when PW_KEY_TARGET_OBJECT is used.
Make the default device metadata node persist for the lifetime of the hotplug loop so the default source/sink devices will be updated if they change during runtime.
With Pipewire now requiring a minimum version 0.3.24, the PW_KEY_CONTEXT_PROFILE_MODULES value is no longer required for legacy compatability and can be safely removed.
* Fix assumption that DRI_DEVNAME begins at 0
The existing logic of the code was to count every possible entry in
KMSDRM_DRI_PATH. After this a for loop would start trying to open
filename0, filename1, filename2, etc. In recent Linux kernels (say
5.18) with simpledrm, the lowest KMSDRM_DRI_DEVNAME is often
/dev/dri/card1, rather than /dev/dri/card0, causing the code to fail
once /dev/dri/card0 has failed to open. Running:
modprobe foodrm && modprobe bardrm && rmmod foodrm
before you try to run an application with SDL KMSDRM would have also
made this fail.
* Various changes from review
- Removed newline and period from SDL error
- Explicitely compare memcmp to zero (also changed to SDL_memcmp)
- Changed memcpy to strncpy
- Less aggressive line wrapping
* Various changes from review
- strncpy to SDL_strlcpy
- removed size hardcodings for KMSDRM_DRI_PATHSIZE and
KMSDRM_DRI_DEVNAMESIZE
- made all KMSDRM_DRI defines, run-time variables to reduce bugs caused
by these defines being more build-time on Linux and more run-rime on
OpenBSD
- renamed openbsd69orgreater variable to moderndri
- altered comment from "if on OpenBSD" to add difference in 6.9
* Various changes from review
- Use max size of destination, rather than max size of source
- Less hardcodings
When building on macOS without gcc (e.g. clang) where HAVE_GCC_ATOMICS
is not defined, `SDL_AtomicTryLock` will call
`OSAtomicCompareAndSwap32Barrier` which is not yet declared.
Including OSAtomic.h on OSX resolves this error/warning:
SDL_spinlock.c:125:12: error: implicit declaration of function
'OSAtomicCompareAndSwap32Barrier' is invalid in
C99 [-Werror,-Wimplicit-function-declaration]
return OSAtomicCompareAndSwap32Barrier(0, 1, lock);
This was reported in issue #3885 but marked Invalid and closed - possibly
because the default CMake build uses gcc instead of clang.
The documentation doesn't state that the argument is ever modified,
and no implementation does so currently.
This is a non-breaking change to guarantee as much to callers.
strchr and strrchr return a pointer to the first/last occurrence of a
character in a string, or NULL if the character is not found. According
to the C standard, the final null terminator is part of the string, and
it should thus be possible to get a pointer to the final null with
these functions. The fallback implementations of SDL_strchr and
SDL_strrchr would always return NULL if trying to find '\0', and this
commit fixes that.
* Xbox GDK support (14 squashed commits)
* Added basic keyboard testing
* Update readme
* Code review fixes
* Fixed issue where controller add/removal wasn't working (since the device notification events don't work on Xbox, have to use the joystick thread to poll XInput)
Also added test functions for multi-line debug text display
Currently this only supports ASCII, as the font doesn't have the correct Latin-1 characters
The HIDAPI joystick driver doesn't properly reset the change counter
it uses to track if re-enumeration is needed when the joystick
subsystem is quit and then reinitialized.
The first SDL_Init(SDL_INIT_JOYSTICK) will result in the expected
HIDAPI joysticks appearing, but subsequent calls will result in no
joysticks being enumerated until another HIDAPI joystick is added
or removed from the system.
Use SDL_lroundf() to round fractional backbuffer sizes halfway away from zero, as this is the rounding method recommended by the forthcoming Wayland fractional scaling protocol.
We might want to use ssize_t as @Guldoman suggested, but that's a larger internal API change, and still requires casting of the SDL_utf8strnlen() result.
Fixes https://github.com/libsdl-org/SDL/pull/5821
This allows us to handle controllers that use the Xbox protocol but look like Nintendo Switch or Playstation controllers, like the Qanba Dragon Arcade Stick in PC mode
This is done such that we can disable LTO for these 2 functions when
building with MSVC.
This is due to a limitation of Link Time Code Generation (LTCG).
Code generation might generate a new reference to memset after linking
has started. The LTCG must make assumptions about where memset is
defined which is normally the C runtime.
Some compositors will provide 'nicer' / 'human readable' output descriptions via the xdg-output protocol. Use these description strings, when available, instead of the model name provided by wl-output. On compositors such as GNOME where this is provided, the display names provided to applications by SDL will now match those in the desktop display settings panel. On compositors where this data isn't provided, the old behavior of using the model string provided by wl-output will remain unchanged.
Additionally, per the protocol spec, output data provided by xdg-output should supersede wl-output data, so this is the recommended behavior in general.
If the width is sufficiently ludicrous, then the calculated pitch or
the image size could conceivably be a signed integer overflow, which
is undefined behaviour. Calculate in the unsigned size_t domain, with
overflow checks.
