Sam Lantinga e9869e07 2020-11-23T21:08:19 Fixed bug 5335 - enable joystick/haptic/evdev support by default on FreeBSD Alex S Evdev headers aren't actually included in the base system (well, it has a private copy), they are available through the devel/evdev-proto port instead. We also have devel/libinotify and devel/libudev-devd shims, I didn't verify whether they work with SDL.
Sam Lantinga 38ab8bf7 2020-11-23T21:03:43 Fixed bug 5362 - Mac OS ARM doesn't build Metal/Vulkan back-end/renderers C.W. Betts As it is, SDL2's built-in config on macOS for Metal excludes Apple Silicon. This is due to thinking that the 64-bit Mac platform would always be x86_64. My patch fixes this by using the catch-all of 64-bit platforms.
Sam Lantinga 62e39b5f 2020-11-23T20:57:14 Fixed building with an older SDK and macOS target

Sam Lantinga fd894467 2020-11-21T14:13:26 Fixed building on Mac OS X on the command line and with an older macOS SDK
Sam Lantinga 1df593fb 2020-11-21T13:15:33 Fixed bug 5355 - Add GameController Framework support to macOS C.W. Betts This patch adds support to the GameController framework on macOS Big Sur and later, adding support for MFi controllers as well as rumble support for PS4 and Xbox One. There is some code to make sure that the IOKit joystick handler doesn't include two controllers at once. While the GameController framework is present in earlier versions of macOS, there was no public, approved way of checking if a specific IOHIDDevice is a controller that GameController could handle. This was changed in Big Sur.
Sam Lantinga fcb21aa8 2020-11-17T10:30:20 Added API for sensors on game controllers Added support for the PS4 controller gyro and accelerometer on iOS and HIDAPI drivers Also fixed an issue with the accelerometer on iOS having inverted axes

Ozkan Sezer bbbec723 2020-11-14T14:03:40 SDL_config_windows.h: define HAVE_TRUNC[F] for Visual Studio >= 2013
Ozkan Sezer 3e40b87f 2020-11-14T14:03:40 SDL_config_os2.h: undefine HAVE_TRUNC trunc() exists only in OpenWatcom 2.0 fork, and its implementation already is the same as the fallback we have here..
Ryan C. Gordon bee8db3b 2020-11-14T02:16:41 config: Make sure HAVE_TRUNC and HAVE_TRUNCF are defined as appropriate. The configure/cmake scripts were checking for these functions but we didn't have the SDL_config.h.* pieces in place. The other config headers are best guesses.
Sam Lantinga 9f51fad3 2020-11-13T18:01:29 Added support for the touchpad on PS4 and PS5 controllers
Sam Lantinga 0500c044 2020-11-12T07:53:05 Fix SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL also applying to HIGH priorities As the name suggests, the hint should only apply to SDL_THREAD_PRIORITY_TIME_CRITICAL The resulting priorities for my current distro result in these values: | High | Time Critical Hint |--------------|----------------- 0 | P=10 N=-10 | P=5 N=-15 1 | P=10 N=-10 | P=-21 N=0

Sam Lantinga 1822f97e 2020-11-11T19:37:47 Fixed bug 5346 - Add FreeBSD evdev KBIO keyboard input driver wahil1976 This patch adds the KBIO text input driver for FreeBSD, which allows text input to fully work without text spilling out into the console. It also supports accented input, AltGr keys and Alt Lock combinations. Tested with US accent keys layout and various AltGr layouts.
Sam Lantinga 1e2caac5 2020-11-11T18:57:37 Added SDL_JoystickRumbleTriggers() and SDL_GameControllerRumbleTriggers()
Sam Lantinga 07eae7d6 2020-11-11T08:47:18 Fix process randomly getting killed when SDL_THREAD_PRIORITY_HIGH/TIME_CRITICAL is set When we request realtime priority from rtkit, we have a rttime limit. If we exceed that limit, the kernel will send SIGKILL to the process to terminate it. This isn't something that most high priority processes will want, only processes that selectively opt into SCHED_RR/FIFO through SDL_HINT_THREAD_PRIORITY_POLICY should be subject to this level of scrutiny. This change: * Switches non-apple posix OSs to use SCHED_OTHER instead of SCHED_RR for SDL_THREAD_PRIORITY_HIGH/SDL_THREAD_PRIORITY_TIME_CRITICAL. * Fixes using a hardcoded RLIMIT_RTTIME, instead queries it from rtkit * Only sets RLIMIT_RTTIME for MakeRealtime rtkit requests * Adds a note regarding the possible SIGKILL with SDL_HINT_THREAD_PRIORITY_POLICY * Introduces SDL_HINT_THREAD_FORCE_REALTIME_TIME_CRITICAL to allow apps to acquire realtime scheduling policies on Linux

Sam Lantinga 86517d3e 2020-08-10T08:42:35 Fixed bug 5242 - KMOD_* flags unnecessarily macros; breaks OGRE Rainer Deyke While most of the KMOD_* flags are enums, the combination flags KMOD_CTRL, KMOD_ALT, KMOD_SHIFT and KMOD_GUI are defined as macros. This breaks third-party code that uses these KMOD_* names for local identifiers, such as OGRE. The correct thing to do is to make them all enums.

Sam Lantinga 7c0986fb 2020-06-12T10:30:46 Fixed bug 4938 - Suggestion: rename SDL_PIXELFORMAT_BGR888 to SDL_PIXELFORMAT_XBGR8888 Ellie I just tripped over this: stb_image when requesting 3 channels with 8-bit actually returns them as 3 bytes per pixel with no alignment, so basically 4 pixels are 12 bytes with no padding (0...2, 3...5, 6...8, and 9...11). This I would have naively expected to be called RGB888 or BGR888, since there is no "dead" unused byte as I would expect for something called e.g. RGBX8888. However, SDL2's SDL_PIXELFORMAT_BGR888 uses 4 bytes, same as SDL_PIXELFORMAT_BGRX8888, even though the latter appears to be a longer storage format - which it isn't, internally. It's just swapped, in byte order X, B, G, R (instead of BGRX). So why isn't the macro name also swapped, as "XBGR888" instead of just "BGR888"? I find the formats therefore named inconsistently, and unless there is a reason for this I suggest these changes: 1. deprecate SDL_PIXELFORMAT_BGR888 in favor of a new SDL_PIXELFORMAT_XBGR8888 and 2. deprecate SDL_PIXELFORMAT_RGB888 in favor of a new SDL_PIXELFORMAT_XRGB8888

Sam Lantinga abd58418 2020-05-26T13:19:19 Make some changes to SDL_SetThreadPriority to try and have SDL transparently handle more of the work. 1. Comment that SDL_SetThreadPriority will make any necessary system changes when applying priority. 2. Add a hint to override SDL's default behavior for scheduler policy. 3. Modify the pthreads SDL_SetThreadPriority so that instead of just using the current thread scheduler policy it will change it to a policy that should work best for the requested priority. 4. Add hint checks in SDL_SetThreadPriority so that #3 can be overridden if desired. 5. Modify the Linux SDL_SetThreadPriority so that in the case that policy, either by SDL defaults or from the hint, is a realtime policy it uses the realtime rtkit API. 6. Prior to calling rtkit on Linux make the necessary thread state changes that rtkit requires. Currently this is done every time as it isn't expected that SDL_SetThreadPriority will be called repeatedly for a thread.
Sam Lantinga eadc8693 2020-05-11T14:31:04 Fixed bug 5103 - Port fcitx support to both fcitx 4 & 5 wengxt Due to the new major fcitx version is coming close, the existing code need to be ported to use new Fcitx dbus interface. The new dbus interface is supported by both fcitx 4 and 5, and has a good side effect, which is that it will work with flatpak for free. Also the patch remove the dependency on fcitx header. Instead, it just hardcodes a few enum value in the code so need to handle the different header for fcitx4 or 5.
Sam Lantinga 65ad4534 2020-05-04T13:17:43 Improvement for bug 3446 - The haptic API does not allow to select the direction axes meyraud705 I see how the documentation is confusing. I think that the choice of the axis is an implementation detail. The documentation should state the goal of this value, so I propose this wording: "Use this value to play an effect on the steering wheel axis. This provides better compatibility across platforms and devices as SDL will guess the correct axis." Value could even be renamed 'SDL_HAPTIC_STEERING_AXIS'. For Linux, sending an effect on the X axis with a Logitech wheel works. Others brands don't have driver for Linux as far as I know.
Ryan C. Gordon fa23e3d0 2020-05-04T02:27:29 locale: Implemented SDL_GetPreferredLocales(). This was something I proposed a long time ago, Sylvain Becker did additional work on it, then back to me. Fixes Bugzilla #2131.

Sam Lantinga aba27928 2020-04-18T21:41:37 Added a Windows Gaming Input joystick driver This driver supports the Razer Atrox Arcade Stick Some of the quirks of this driver, inherent in Windows Gaming Input: * There will never appear to be controllers connected at startup. You must support hot-plugging in order to see these controllers. * You can't read the state of the guide button * You can't get controller events in the background
Sam Lantinga ed1d8558 2020-04-14T07:41:00 Fixed bug 4299 - A recent change requires Core Bluetooth framework on iOS Caleb Cornett Just ran into this, and from my testing, whatever re-added the dependency is a _major_ regression. Not only is your app forced to link with CoreBluetooth, but iOS has apparently tightened up security and won't even let you _test_ your app unless it specifies the NSBluetoothAlwaysUsageDescription in an Info.plist. It doesn't even pop up an error message, it just straight up crashes. Adding the permission isn't a good solution either, since I'd really, really rather not have my app request users' bluetooth to always be enabled, especially if the only apparent reason is for Steam Controller support.

Ryan C. Gordon d292f6bd 2020-04-10T12:17:14 stdlib: Add SDL_trunc and SDL_truncf
Ryan C. Gordon a7916890 2020-04-10T00:37:35 metal: Added some support interfaces to Apple's Metal API (thanks, Caleb!). Caleb Cornett's comments: "A few weeks ago, Alex added a partial Metal API to SDL2: https://hg.libsdl.org/SDL/rev/22c8e7cd8d38 I noticed it was missing a few features that would help Metal become a first-class citizen in SDL, so I went ahead and wrote them! Here are the new APIs: 1. SDL_WINDOW_METAL flag for SDL_CreateWindow(). This allows the programmer to specify that they intend to create a window for use with SDL_MetalView. The flag is used to ensure correct usage of the API and to prevent accidentally defaulting to OpenGL on iOS. 2. SDL_Metal_GetLayer(). This function takes a SDL_MetalView and returns a pointer to the view's backing CAMetalLayer. This simplifies things considerably, since in the current version of the SDL_Metal API the programmer is required to bridge-cast a SDL_MetalView handle to an NSView or UIView (depending on the platform) and then extract the layer from there. SDL_Metal_GetLayer automatically handles all of that, making the operation simple and cross-platform. 3. SDL_Metal_GetDrawableSize(). This function already exists in the current SDL_Metal API (and is used behind-the-scenes for SDL_Vulkan_GetDrawableSize on Apple platforms) but was not publicly exposed. My patch exposes this function for public use. It works just like you'd expect. Tested on macOS 10.14 and iOS 12.4." Fixes Bugzilla #4796.

Sam Lantinga 73799917 2020-03-16T13:28:38 Fixed bug 3446 - The haptic API does not allow to select the direction axes Mathieu Laurendeau Consider a device supporting effects on multiple axes. There's currently no way to play effects against a single-axis direction. A device supporting effects against X and Y may not allow to play effects with a two-axis direction coordinate, even if one of the coordinates is null. My current (ugly) work around for this is to add a direction type SDL_HAPTIC_X_FORCE to play effects against a X-axis only direction (patch attached). This issue impacted two GIMX users using the following wheels: - Leo Bodnar SimSteering force feedback wheel - Accuforce direct drive wheel Playing constant/spring/damper effects against a X-axis direction worked well for the first wheel, but not for the second one. A better strategy seems to play the effects against the first axis reported by the DirectInput enumeration. This strategy also works with Logitech wheels (at least the DFGT). It's been more than a year that I have the latest patch (playing effects against the first axis only) in the GIMX software. It's being used by thousands of people, mostly for adapting their FFB wheel to the PS4. I had no report that proves this strategy to be wrong.
Sam Lantinga 4dea340c 2020-03-16T12:23:38 Fixed bug 4477 - Support more than 4 XInput-capable devices on Windows Jimb Esser Add new RawInput controller API, and improved correlation with XInput/WGI Reorder joystick init so drivers can ask the others if they handle a device reliably Do not poll disconnected XInput devices (major perf issue) Fix various cases where incorrect correlation could happen Simple mechanism for propagating unhandled Guide button presses even before guaranteed correlation Correlate by axis motion as well as button presses Fix failing to zero other trigger Fix SDL_HINT_JOYSTICK_HIDAPI not working if set before calling SDL_Init() Add missing device to device names Disable RawInput if we have a mismatch of XInput-capable but not RawInput-capable devices Updated to SDL 2.0.13 code with the following notes: New HID driver: xbox360w - no idea what that is, hopefully urelated SDL_hidapijoystick.c had been refactored to couple data handling logic with device opening logic and device lists caused some problems, yields slightly uglier integration than previously when the 360 HID device driver was just handling the data. SDL_hidapijoystick.c now often pulls the device off of the joystick_hwdata structure for some rumble logic, but it appears that code path is never reached, so probably not a problem. Looks like joystick_hwdata was refactored to not include a mutex in other drivers, maintainers may want to do the same refactor here if that's useful for some reason. Something changed in how devices get names, so getting generic names. Had to fix a (new?) bug where removing an XInput controller caused existing controllers (that moved to a new XInput index) to get identified as 0x045e/0x02fd ("it's probably Bluetooth" in code), rendering the existing HIDAPI_IsDevicePresent and new RAWINPUT_IsDevicePresent unreliable.

Sam Lantinga 2be75c6a 2020-03-13T19:08:45 Fixed bug 5028 - Virtual Joysticks (new joystick backend) David Ludwig I have created a new driver for SDL's Joystick and Game-Controller subsystem: a Virtual driver. This driver allows one to create a software-based joystick, which to SDL applications will look and react like a real joystick, but whose state can be set programmatically. A primary use case for this is to help enable developers to add touch-screen joysticks to their apps. The driver comes with a set of new, public APIs, with functions to attach and detach joysticks, set virtual-joystick state, and to determine if a joystick is a virtual-one. Use of virtual joysticks goes as such: 1. Attach one or more virtual joysticks by calling SDL_JoystickAttachVirtual. If successful, this returns the virtual-device's joystick-index. 2. Open the virtual joysticks (using indicies returned by SDL_JoystickAttachVirtual). 3. Call any of the SDL_JoystickSetVirtual* functions when joystick-state changes. Please note that virtual-joystick state will only get applied on the next call to SDL_JoystickUpdate, or when pumping or polling for SDL events (via SDL_PumpEvents or SDL_PollEvent). Here is a listing of the new, public APIs, at present and subject to change: ------------------------------------------------------------ /** * Attaches a new virtual joystick. * Returns the joystick's device index, or -1 if an error occurred. */ extern DECLSPEC int SDLCALL SDL_JoystickAttachVirtual(SDL_JoystickType type, int naxes, int nballs, int nbuttons, int nhats); /** * Detaches a virtual joystick * Returns 0 on success, or -1 if an error occurred. */ extern DECLSPEC int SDLCALL SDL_JoystickDetachVirtual(int device_index); /** * Indicates whether or not a virtual-joystick is at a given device index. */ extern DECLSPEC SDL_bool SDLCALL SDL_JoystickIsVirtual(int device_index); /** * Set values on an opened, virtual-joystick's controls. * Returns 0 on success, -1 on error. */ extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualAxis(SDL_Joystick * joystick, int axis, Sint16 value); extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualBall(SDL_Joystick * joystick, int ball, Sint16 xrel, Sint16 yrel); extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualButton(SDL_Joystick * joystick, int button, Uint8 value); extern DECLSPEC int SDLCALL SDL_JoystickSetVirtualHat(SDL_Joystick * joystick, int hat, Uint8 value); ------------------------------------------------------------ Miscellaneous notes on the initial patch, which are also subject to change: 1. no test code is present in SDL, yet. This should, perhaps, change. Initial development was done with an ImGui-based app, which potentially is too thick for use in SDL-official. If tests are to be added, what kind of tests? Automated? Graphical? 2. virtual game controllers can be created by calling SDL_JoystickAttachVirtual with a joystick-type of SDL_JOYSTICK_TYPE_GAME_CONTROLLER, with naxes (num axes) set to SDL_CONTROLLER_AXIS_MAX, and with nbuttons (num buttons) set to SDL_CONTROLLER_BUTTON_MAX. When updating their state, values of type SDL_GameControllerAxis or SDL_GameControllerButton can be casted to an int and used for the control-index (in calls to SDL_JoystickSetVirtual* functions). 3. virtual joysticks' guids are mostly all-zeros with the exception of the last two bytes, the first of which is a 'v', to indicate that the guid is a virtual one, and the second of which is a SDL_JoystickType that has been converted into a Uint8. 4. virtual joysticks are ONLY turned into virtual game-controllers if and when their joystick-type is set to SDL_JOYSTICK_TYPE_GAMECONTROLLER. This is controlled by having SDL's default list of game-controllers have a single entry for a virtual game controller (of guid, "00000000000000000000000000007601", which is subject to the guid-encoding described above). 5. regarding having to call SDL_JoystickUpdate, either directly or indirectly via SDL_PumpEvents or SDL_PollEvents, before new virtual-joystick state becomes active (as specified via SDL_JoystickSetVirtual* function-calls), this was done to match behavior found in SDL's other joystick drivers, almost all of which will only update SDL-state during SDL_JoystickUpdate. 6. the initial patch is based off of SDL 2.0.12 7. the virtual joystick subsystem is disabled by default. It should be possible to enable it by building with SDL_JOYSTICK_VIRTUAL=1 Questions, comments, suggestions, or bug reports very welcome!

Sam Lantinga 4b585e75 2020-02-03T08:06:52 Fixed bug 4833 - Use EGL for X11? Martin Fiedler To be precise, this is about *desktop OpenGL* on X11. For OpenGL ES, EGL is already used (as it's the only way to get an OpenGL ES context), as Sylvain noted above. To shine some light on why this is needed: In 99% of all cases, using GLX on X11 is fine, even though it's effectively deprecated in favor of EGL [1]. However, there's at least one use case that *requires* the OpenGL context being created with EGL instead of GLX, and that's DRM_PRIME interoperability: The function glEGLImageTargetTexture2DOES simply doesn't work with GLX. (Currently, Mesa actually crashes when trying that.) Some example code: https://gist.github.com/kajott/d1b29c613be30893c855621edd1f212e Runs on Intel and open-source AMD drivers just fine (others unconfirmed), but with #define USE_EGL 0 (i.e. forcing it to GLX), it crashes. The same happens when using SDL for window and context creation. The good news is that most of the pieces for EGL support on X11 are already in place: SDL_egl.c is pretty complete (and used for desktop OpenGL on Wayland, for example), and SDL_x11opengl.c has the aforementioned OpenGL-ES-on-EGL support. However, when it comes to desktop OpenGL, it's hardcoded to fall back to GLX. I'm not advocating to make EGL the default for desktop OpenGL on X11; don't fix what ain't broken. But something like an SDL_HINT_VIDEO_X11_FORCE_EGL would be very appreciated to make use cases like the above work with SDL.

Sam Lantinga 981e0d36 2020-01-16T08:52:59 Fixed bug 4903 - Lack of color multiply with alpha (SDL_BLENDMODE_MOD + SDL_BLENDMODE_BLEND) blending mode for all renderers Konrad This kind of blending is rather quite useful and in my opinion should be available for all renderers. I do need it myself, but since I didn't want to use a custom blending mode which is supported only by certain renderers (e.g. not in software which is quite important for me) I did write implementation of SDL_BLENDMODE_MUL for all renderers altogether. SDL_BLENDMODE_MUL implements following equation: dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA)) dstA = (srcA * dstA) + (dstA * (1-srcA)) Background: https://i.imgur.com/UsYhydP.png Blended texture: https://i.imgur.com/0juXQcV.png Result for SDL_BLENDMODE_MOD: https://i.imgur.com/wgNSgUl.png Result for SDL_BLENDMODE_MUL: https://i.imgur.com/Veokzim.png I think I did cover all possibilities within included patch, but I didn't write any tests for SDL_BLENDMODE_MUL, so it would be lovely if someone could do it.
