valfenceSyncObject = GLES30.glFenceSync(GLES30.GL_SYNC_GPU_COMMANDS_COMPLETE,0) 这个方法调用后会往当前线程的命令队列中插入一个 fence 并返回一个long型变量来代码这个fence同步对象,以便于其它地方去等待它。 有2个方法可以用于等待,glWaitSync 和 glClientWaitSync,它们的差别是glWaitSync 是在 GPU 上等...

接收in-fences意味着我们需要在使用与in-fences相关的任何缓冲区之前等待fence(s)发出信号。 创建Sync Files 当驱动程序需要向用户空间发送out-fence时,它创建一个sync_file。 接口: struct sync_file *sync_file_create(struct dma_fence *fence); 调用者传递out-fence并获得sync_file。这只是第一步,接下来需要...
structsync_file *sync_file_create(structdma_fence *fence); 调用者传递out-fence并获得sync_file。这只是第一步,接下来需要在sync_file->file上安装一个fd。因此,它获取一个fd: fd = get_unused_fd_flags(O_CLOEXEC); 并将其安装在sync_file->file上: ...

I think the actual issue here is that SDL_render_gpu.c is waiting for the present fence on every submission, which will effectively limit the framerate to the presentation timing. Contributor Akaricchi commented Aug 31, 2024 Why does Vulkan behave differently? Also you still got about 500 ...
