Steven Noonan a01a566c 2023-06-09T00:31:06 extension xmls: fix incorrect use of <ptype> tags I was having trouble using some GL/EGL loader generators because of some errors in the XML definitions for ANGLE. The first major problem is the content of the <ptype> tags. Let's refer to the Khronos registry XML schema (which is annoyingly a PDF rather than an xsd that we can test against, though I don't know if an xsd would catch this anyway): https://raw.githubusercontent.com/KhronosGroup/OpenGL-Registry/master/xml/readme.pdf In section 12.4.2, "Contents of <param> tags" it states: The <ptype> tag is optional, and contains text which is a valid type name found in <type> tag, and indicates that this type must be previously defined for the definition of the command to succeed. Builtin C types, and any derived types which are expected to be found in other header files, should not be wrapped in <ptype> tags Note that the above is repeated for the contents of <proto> tags as well. The extension XML files currently have a bunch of <ptype> tags which don't meet the expectations described above. The correct transformation for them would be, for example: <ptype>GLfloat *</ptype> -> <ptype>GLfloat</ptype> * <ptype>void *</ptype> -> void * <ptype>const char *</ptype> -> const char * <ptype>EGLAttrib *</ptype> -> <ptype>EGLAttrib</ptype> * The next issue is that some tags have some typos, such as "<pytpe>" instead of "<ptype>". (Now *that* is something an .xsd would catch...) The last issue is the use of the typename "GLvoid" which is not as serious a problem. It is still defined in Khronos' gl.xml <types> block, but Khronos no longer uses it in their XML registries. The comment for the "GLvoid" type in their <types> block states: <type comment="Not an actual GL type, though used in headers in the past">typedef void <name>GLvoid</name>;</type> So we might as well replace those with just plain "void". Anyway, long story short: to apply these transformations, I used Perl regular expressions, and applied these expressions in order: - Fix the tag misspellings: s#<(/?)pytpe>#<\1ptype>#g - Move the const qualifiers (if present) and pointer asterisk(s) (if any) outside the <ptype> tag itself: s#<ptype>(const )?([A-Za-z0-9]+)[ ]?(\*\*?)</ptype> #\1<ptype>\2</ptype> \3#g - Replace "GLvoid", "char", and "void" inside ptype tags to normal C types outside tags: s#<ptype>(GLvoid|void|char)</ptype>#\1#g Bug: angleproject:8190 Change-Id: Ib0bea79fecb7e714910b6e92124bb9f52994d0fb Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4603709 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org>

Dan Glastonbury aa5b97de 2023-03-06T17:59:43 ANGLE_metal_shared_event_sync: Control signaling external events It was assumed that the external MTLSharedEvent passed to eglCreateSync should be signaled by the GL. This change adds EGL_SYNC_METAL_SHARED_EVENT_SIGNALED_ANGLE, which when passed as the value for EGL_SYNC_CONDITION during eglCreateSync, changes the behavior to not insert a fence command into the command stream.

Gregg Tavares be9e8e7b 2022-12-14T14:13:39 Add EGL_ANGLE_wait_until_work_scheduled extension We're changing eglReleaseTexImage so it calls flushCommandBuffer(mtl::NoWait) instead of flushCommandBuffer(mtl::WaitUntilScheduled) and then adding an extension to allow us to WaitUntilScheduled. This is because Chrome calls eglReleaseTexImage for every canvas and having it WaitUntilScheduled per call is very slow. So instead we'll call eglWaitUntilWorkScheduledANGLE once which will effectively wait just once.

Dan Glastonbury d2a58f00 2022-09-08T14:19:21 EGL: Implement eglCopyMetalSharedEventANGLE Add eglCopyMetalSharedEventANGLE function to the ANGLE_metal_shared_event_sync extension. This brings the extension on par with the EGL_ANDROID_native_fence_sync extension. eglCopyMetalSharedEventANGLE allows for copying the Metal event object from EGLSync objects implemented by the ANGLE Metal renderer. This function follows Objective-C convention for "copy" methods and increases the retain count of the Metal event object.

This lets the caller figure out the GPU in another process. Then the caller can just set the GPU in the sandboxed process.

Lingfeng Yang 926b43e7 2022-01-06T13:31:54 Reland: Frontend: separate lock in swap prep Swapchain-based backends like Vulkan might block a lot in vkAcquireNextImageKHR, which is bad for overall fast progress if we also hold the global EGL lock there. This CL starts to split the global EGL lock. We release the EGL lock when performing vkAcquireNextImageKHR, and only maintain a lock for surfaces. This is done via a new custom entry point, EGL_PrepareSwapBuffers, so that we can control how the global lock is used throughout the entire call.

Kenneth Russell af727792 2020-06-10T21:55:43 Improve EGL_ANGLE_power_preference on dual-GPU MacBook Pros. Add the ability to release and reacquire the high-power GPU, and to respond to changes in the active GPU. In Chromium, the GPU process can not access the WindowServer. An external process must inform ANGLE that the active GPU has changed, and that ANGLE should switch its internal context to the new GPU. Incorporates a couple of functions from WebKit, used with permission, to effect this GPU switch. A follow-on change in Chromium which uses these new APIs will make the existing dual-GPU tests pass with ANGLE and the passthrough command decoder. Carry forward Chromium's workaround of disabling GPU switching on older MacBook Pros to ensure stability. Document the process of adding new EGL extensions to ANGLE.
