There is parameter named powerManagement for GPU driver of i.MX6.
Could you give me a description about the PM function of i.MX6 GPU?
And in the GPU driver gc_hal_kernel_probe.c(linux-imx-4.1.15/drivers/mxc/gpu-viv/hal/os/linux/kernel)),
the default value for powerManagement is -1.What does -1 mean. My understand is 0 for disable and 1 for enable.I cannot understand -1.
