器件型号：PROCESSOR-SDK-AM437X 工具/软件：
Hello Im、使用 TISDK 09.01.00.001 (2023年10月)
我正在尝试将 wpewebkit 应用程序包含到映像中。
Im 在启动 COG (网络浏览器)时出现问题。
问题似乎与 PVR 驱动程序有关。 这是日志：
root@am437x-alx:~# cog -P drm http://example.com MESA: info: Loaded libpvr_dri_support.so (cog:1115): Cog-DRM-WARNING **: 19:10:30.599: Renderer 'modeset' does not support rotation 0 (0 degrees).

在日志中、您可以看到页面已加载、但在呈现时会失败
如果在运行命令之前卸载 pvrsrvkm.ko 驱动程序、它仍然会出现错误、但我认为它默认为软件渲染。

类似地、如果我在命令之前导出此变量以强制软件呈现、它将起作用：
导出 LIBGL_ALWAYS_SOFTWARE=1
我将向 wpewebkit 添加 gles2和 EGL 软件包配置(在它未运行之前)。 我找不到任何好的提示的错误消息,我真的不想依赖软件渲染 我会感激你的支持.
