linux: stable: remove DPC attribute from meson-g12 gpu node #113

Closed CodeChenL closed 5 days ago

CodeChenL commented 1 week ago

Fixes a situation where the GPU has been limited to the lowest frequency by the temperature system even though the DDR temperature is very low

CodeChenL commented 1 week ago

用户有反馈cpu频率也很低，看看是不是同样的原因

使用stress-ng单线程正常跑到1800M。四线程只能跑到1600M左右，全程使用风扇，温度稳定在36摄氏度

CodeChenL commented 1 week ago

感觉你说的内核崩溃是不是发生在zero2上，zero2额外加了风扇节点和trips

RadxaYuntian commented 1 week ago

是的。pwm-fan这个设备在thermal子系统里面跟别的设备不太一样

CodeChenL commented 1 week ago

zero与zero 2 pro均已cpu gpu双烤一小时测试

CodeChenL commented 5 days ago

现在的状态是70度开始降频，跑分时，gpu调度器默认target_freq是第二档（查看/sys/class/thermal/信息并没有触发温控，温控再宽松也一样），max_freq正常，基本上正常了
