Tool/software:
Hi,
I am trying to disable APM events on the on-board GPU since it is having a noticeable effect on our program but I am unable to do so correctly.
So far I have tried disabling the following kernel configurations:
CONFIG_ENERGY_MODEL=n CONFIG_SUSPEND=n CONFIG_WQ_POWER_EFFICIENT_DEFAULT=n # CONFIG_PM=n # Causes kernel panic CONFIG_PM_SLEEP=n CONFIG_HIBERNATION=n CONFIG_CPU_PM=n CONFIG_CPU_IDLE=n CONFIG_ARCH_SUSPEND_POSSIBLE=n CONFIG_PM_CLK=n # Doesn't work without CONFIG_PM=n CONFIG_PM_GENERIC_DOMAINS=n CONFIG_PM_GENERIC_DOMAINS_OF=n CONFIG_CPU_FREQ_GOV_POWERSAVE=n CONFIG_CPU_FREQ_GOV_CONSERVATIVE=n CONFIG_ARCH_HIBERNATION_POSSIBLE=n CONFIG_ARCH_SUSPEND_POSSIBLE=n CONFIG_ACPI=n
And I am unable to find any config options relating to APM which I find unusual since it is enabled and running on the board.
Here is my PVR dump in case it is of any use:

I am using the ti-linux-staging 6.6 kernel.
I have also tried the recommended method from this TI document for disabling APM but it had no effect.
Please let me know the correct method for disabling APM.
