I have just tested it and it seems that at least something is working now[1]!! Thanks for the work. It also seems that the screen is only frozen when it encounters some failures (e.g. when dealing with 3d images), is it possible to detect these and make it fail less violently? [Rong]: Screen frozen may be GPU hang, can you provide your tests or kernel, then I will reproduce and fix it. > But because of the drm kernel driver's restrict, if you want to run OpenCL > applications with local memory enabled, you should apply the attached patch > to your kernel, otherwise, the application will fail. Is this the only way to workaround this issue or is there any plan to get a fix upstream? May also be great if this can at least be changed dynamically. [Rong]: Yes, must hack the kernel to walk around it now, and the drm driver team is handling it now, but maybe need some time. Looking forward to full support soon.
