3bef4a5d	2022-01-22T15:43:09	cleanup error-handling in SDL_egl.c - always set error message in SDL_EGL_ChooseConfig / SDL_EGL_CreateContext - assume SDL_EGL_DeleteContext does not alter the error message - sync generic error message of SDL_EGL_MakeCurrent with SDL_EGL_Get/SetSwapInterval - do not overwrite error message of SDL_EGL_ChooseConfig in WINRT_CreateWindow

8f38ba4d	2021-07-29T18:02:47	Fix casts that should be using uintptr_t This is needed to support CHERI, and thus Arm's experimental Morello prototype, where pointers are implemented using unforgeable capabilities that include bounds and permissions metadata to provide fine-grained spatial and referential memory safety, as well as revocation by sweeping memory to provide heap temporal memory safety. On most systems (anything with a flat memory hierarchy rather than using segment-based addressing), size_t and uintptr_t are the same type. However, on CHERI, size_t is just an integer offset, whereas uintptr_t is still a capability as described above. Casting a pointer to size_t will strip the metadata and validity tag, and casting from size_t to a pointer will result in a null-derived capability whose validity tag is not set, and thus cannot be dereferenced without faulting. The audio and cursor casts were harmless as they intend to stuff an integer into a pointer, but using uintptr_t is the idiomatic way to do that and silences our compiler warnings (which our build tool makes fatal by default as they often indicate real problems). The iconv and egl casts were true positives as SDL_iconv_t and iconv_t are pointer types, as is NativeDisplayType on most OSes, so this would have trapped at run time when using the round-tripped pointers. The gles2 casts were also harmless; the OpenGL API defines this argument to be a pointer type (and uses the argument name "pointer"), but it in fact represents an integer offset, so like audio and cursor the additional idiomatic cast is needed to silence the warning.
e1db4b82	2021-05-11T14:08:17	egl: Don't crash if we failed halfway through SDL_CreateWindow.
7b284dbb	2021-04-30T22:01:48	EglChooseConfig: choose an accelerated configuration - especially because we can be promoted to true color 888 make sure we don't select a potentially software implementation - hopefully fix bug #1482 (EGL ChooseConfig selects software renderer on Android)

98a966d1	2021-04-22T18:06:17	Android: don't need to set the SurfaceHolder format from java code It's already set with ANativeWindow_setGeometry, and eventually set/changed also by eglCreateWindowSurface. - avoid issues with older device where SurfaceView cycle create/changed/destroy appears broken: calling create/changed/changed, and leading to "deuqueBuffer failed at server side, error: -19", with black screen. - re-read the format after egl window surface is created, to report the correct one (sometimes, changed from RGBA8888 to RGB24)
6be9c009	2021-04-20T13:46:25	Android: prevent error EGL_BAD_DISPLAY while getting egl version without display There is an error "E libEGL : validate_display:91 error 3008 (EGL_BAD_DISPLAY)" that occurs when calling "eglQueryString(display, EGL_VERSION)", with EGL_NO_DISPLAY. Khronos says "EGL_BAD_DISPLAY is generated if display is not an EGL display connection, unless display is EGL_NO_DISPLAY and name is EGL_EXTENSIONS." but this was added in SDL with "EGL 1.5 allows querying for client version" ( https://github.com/libsdl-org/SDL/commit/56363ebf6124b345e1cfbd14fb6c0e654837910c ) In fact: - it actually doesn't work on Android that has 1.5 egl client - it works on desktop X11 (using SDL_VIDEO_X11_FORCE_EGL=1) The commit moves the version call where it's used, eg inside the "if (platform) {" and checks that "eglGetPlatformDisplay" has been correctly loaded.
354cabd4	2021-04-03T18:15:50	egl: favor truecolor configurations. If app requested <= 16 color depth and there is a 24-bit config available, favor that. This fixes things that quietly expect to get truecolor output but don't request it (...like SDL's render api...) and things that are probably requesting 16-bit color as a fallback but expecting reasonable systems to give them full depth. Specifically, this fixes Life is Strange on Wayland, which uses the latter approach, and anything using SDL_Render on Wayland, which uses the former. Fixes #4056. Fixes #4132.
4abe3446	2021-04-03T10:10:58	SDL_EGL_ChooseConfig: cleanups and minor optimizations. - Move an immutable condition out of a for loop. - Add a break statement to that loop when we find what we're looking for. - Add an assert to make sure we don't overflow a buffer. - Wrap a single-statement if block in braces. - Adjust some whitespace.

8babda2c	2020-07-16T13:18:19	egl: SDL_EGL_LoadLibaryOnly() shouldn't set _this->gl_config.driver_loaded = 1 This is handled in in the higher-level SDL_GL_LoadLibrary(). All uses of SDL_EGL_LoadLibrary (which calls the Only version) are just target-specific wrappers for their own GL_LoadLibrary hook, with two exceptions which now handle driver_loaded correctly (although it's questionable if these init-if-no-one-did-it-correctly-already code blocks should exist at all, fwiw). Fixes Bugzilla #5190.

c0a875fa	2020-04-13T14:48:38	SDL_EGL_ChooseConfig: don't fall through if no matching format exists On Raspberry Pi 3 via the VC4 driver in firmware KMS mode, none of the found configs match the desired format, causing the function to fall through without any config being selected. Fix by first iterating over the found configs, and if no match exists, don't exclude the non-matching configs. This should fix RPI3 and possibly other targets without breaking targets that have a matching native format (such as RPI4).
64617d25	2020-04-13T14:45:40	opengl: Convert an int to an SDL_bool.
389c8995	2020-04-13T14:44:21	opengl: Allow SDL_GL_MakeCurrent() to accept a NULL window (thanks, Martin!). This allows you to bind surfaceless contexts on a background thread to, for example, load assets in a separate context, for platforms that have different requirements about sharing surfaces, etc. Martin's notes on the matter: "Here's a patch that enables passing NULL windows to SDL_GL_MakeCurrent, if the involved APIs allow it. Currently, this is only the case for EGL, and even then only if some specific extensions are present (which they usually are). If "surfaceless" contexts are not supported, SDL_GL_MakeCurrent continues to generate an error (albeit with a more specific error message than it used to), so this should not break anything that wasn't broken before." (Please see https://bugzilla.libsdl.org/show_bug.cgi?id=3695 for more discussion.) Fixes Bugzilla #3695.
b6afbe63	2020-04-07T09:38:57	Added SDL_log.h to SDL_internal.h so logging is available everywhere
90f9e8f8	2020-03-20T15:13:09	egl: Don't use SDL_LoadFunction to get GL entry points on Emscripten. This results in a dlsym() call, which causes Emscripten to panic if the game wasn't explicitly built dlopen support. eglGetProcAddress works just fine on this platform, so just let that codepath handle it.

3ecce847	2019-10-18T00:07:32	egl: adjust how we load symbols in SDL_EGL_GetProcAddress. Use eglGetProcAddress for everything on EGL >= 1.5. Try SDL_LoadFunction first for EGL <= 1.4 in case it's a core symbol, and as a fallback if eglGetProcAddress fails. Finally, for EGL <= 1.4, fallback to eglGetProcAddress to catch extensions not exported from the shared library. (Maybe) Fixes Bugzilla #4794.

aeee424f	2018-10-31T15:16:51	Fixed bug 4349 - SDL_CreateWindow fails with KMS/DRM after upgrading Mesa to 18.2.3 Rainer Sabelka After I did an upgrade of my arch Linux installation (resulting in an update of Mesa to version 18.2.3), all my SDL2 applications which use the KMS/DRM driver stopped working. Reason: Creating a Window with SDL_CreateWindow failed because the call to EGL eglCreateWindowSurface() returns an error "EGL_BAD_MATCH". After investigating with the debugger I figured, that the configuration, which has been selected from the output of eglChooseConfig(), has an "EGL_NATIVE_VISUAL_ID" which does not match the "format" of the underlying gbm surface. The attached patch fixes the problem. It does so, by mimicking Weston's behavior. All configurations returned from eglChooseConfig() which have an visual_id different from the gbm format are discarded, and only from the remaining ones the "best" match is selected.

003d491f	2017-08-27T19:05:57	Fixed bug 3724 - Allow Angle Static Link Carlos We would like to add a switch (define) that allows us to compile Angle statically with SDL. That is, getting rid of the OpenGL DLL. Usually you need OpenGL to be loaded dynamically as DLL because implementation is provided by the system but no need with Angle. Only 2 files need modification and it shouldn't affect current behaivor: include/SDL_egl.h and src/video/SDL_egl.c, as in here https://github.com/native-toolkit/sdl/pull/10/files The flag name could be SDL_VIDEO_STATIC_ANGLE (instead of NATIVE_TOOLKIT_STATIC_ANGLE) as discussed here https://github.com/native-toolkit/sdl/pull/10 We have tested this with both Windows and UWP, using NME engine (https://github.com/haxenme/nme).

Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition. X86 systems use KMS right away in every current GNU/Linux system. Simple build instructions: $./autogen.sh $./configure --enable-video-kmsdrm $make

0e45984f	2015-06-21T17:33:46	Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802

Fix casts that should be using uintptr_t This is needed to support CHERI, and thus Arm's experimental Morello prototype, where pointers are implemented using unforgeable capabilities that include bounds and permissions metadata to provide fine-grained spatial and referential memory safety, as well as revocation by sweeping memory to provide heap temporal memory safety. On most systems (anything with a flat memory hierarchy rather than using segment-based addressing), size_t and uintptr_t are the same type. However, on CHERI, size_t is just an integer offset, whereas uintptr_t is still a capability as described above. Casting a pointer to size_t will strip the metadata and validity tag, and casting from size_t to a pointer will result in a null-derived capability whose validity tag is not set, and thus cannot be dereferenced without faulting. The audio and cursor casts were harmless as they intend to stuff an integer into a pointer, but using uintptr_t is the idiomatic way to do that and silences our compiler warnings (which our build tool makes fatal by default as they often indicate real problems). The iconv and egl casts were true positives as SDL_iconv_t and iconv_t are pointer types, as is NativeDisplayType on most OSes, so this would have trapped at run time when using the round-tripped pointers. The gles2 casts were also harmless; the OpenGL API defines this argument to be a pointer type (and uses the argument name "pointer"), but it in fact represents an integer offset, so like audio and cursor the additional idiomatic cast is needed to silence the warning.

Android: prevent error EGL_BAD_DISPLAY while getting egl version without display There is an error "E libEGL : validate_display:91 error 3008 (EGL_BAD_DISPLAY)" that occurs when calling "eglQueryString(display, EGL_VERSION)", with EGL_NO_DISPLAY. Khronos says "EGL_BAD_DISPLAY is generated if display is not an EGL display connection, unless display is EGL_NO_DISPLAY and name is EGL_EXTENSIONS." but this was added in SDL with "EGL 1.5 allows querying for client version" ( https://github.com/libsdl-org/SDL/commit/56363ebf6124b345e1cfbd14fb6c0e654837910c ) In fact: - it actually doesn't work on Android that has 1.5 egl client - it works on desktop X11 (using SDL_VIDEO_X11_FORCE_EGL=1) The commit moves the version call where it's used, eg inside the "if (platform) {" and checks that "eglGetPlatformDisplay" has been correctly loaded.

egl: favor truecolor configurations. If app requested <= 16 color depth and there is a 24-bit config available, favor that. This fixes things that quietly expect to get truecolor output but don't request it (...like SDL's render api...) and things that are probably requesting 16-bit color as a fallback but expecting reasonable systems to give them full depth. Specifically, this fixes Life is Strange on Wayland, which uses the latter approach, and anything using SDL_Render on Wayland, which uses the former. Fixes #4056. Fixes #4132.

SDL_EGL_ChooseConfig: don't fall through if no matching format exists On Raspberry Pi 3 via the VC4 driver in firmware KMS mode, none of the found configs match the desired format, causing the function to fall through without any config being selected. Fix by first iterating over the found configs, and if no match exists, don't exclude the non-matching configs. This should fix RPI3 and possibly other targets without breaking targets that have a matching native format (such as RPI4).

opengl: Allow SDL_GL_MakeCurrent() to accept a NULL window (thanks, Martin!). This allows you to bind surfaceless contexts on a background thread to, for example, load assets in a separate context, for platforms that have different requirements about sharing surfaces, etc. Martin's notes on the matter: "Here's a patch that enables passing NULL windows to SDL_GL_MakeCurrent, if the involved APIs allow it. Currently, this is only the case for EGL, and even then only if some specific extensions are present (which they usually are). If "surfaceless" contexts are not supported, SDL_GL_MakeCurrent continues to generate an error (albeit with a more specific error message than it used to), so this should not break anything that wasn't broken before." (Please see https://bugzilla.libsdl.org/show_bug.cgi?id=3695 for more discussion.) Fixes Bugzilla #3695.

Finally, for EGL <= 1.4, fallback to eglGetProcAddress to catch extensions not exported from the shared library. (Maybe) Fixes Bugzilla #4794.

Fixed bug 4349 - SDL_CreateWindow fails with KMS/DRM after upgrading Mesa to 18.2.3 Rainer Sabelka After I did an upgrade of my arch Linux installation (resulting in an update of Mesa to version 18.2.3), all my SDL2 applications which use the KMS/DRM driver stopped working. Reason: Creating a Window with SDL_CreateWindow failed because the call to EGL eglCreateWindowSurface() returns an error "EGL_BAD_MATCH". After investigating with the debugger I figured, that the configuration, which has been selected from the output of eglChooseConfig(), has an "EGL_NATIVE_VISUAL_ID" which does not match the "format" of the underlying gbm surface. The attached patch fixes the problem. It does so, by mimicking Weston's behavior. All configurations returned from eglChooseConfig() which have an visual_id different from the gbm format are discarded, and only from the remaining ones the "best" match is selected.

Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
