--- Comment #4 from Alex Deucher <alexdeucher at gmail.com> --- Created attachment 126951 --> https://bugzilla.kernel.org/attachment.cgi?id=126951&action=edit possible fix for SI Starting with 3.13, the driver automatically powers down the dGPU on hybrid laptops when it's not in use. Accessing the sysfs and debufgs information when it's powered down is invalid since the gpu is powered down. This patch returns sensible values when you try to get/set this information when the GPU is powered off. -- You are receiving this mail because: You are watching the assignee of the bug.
