it will cause hwmon node of power1_label is not created. v2: the hwmon node of "power1_label" is always needed for all ASICs. and the patch will remove ASIC type check for "power1_label".

amdgpu/pm: Make sysfs pm attributes as read-only for VFs

2021-12-30T13:54:45Z

== Description == Setting values of pm attributes through sysfs should not be allowed in SRIOV mode. These calls will not be processed by FW anyway, but error handling on sysfs level should be improved. == Changes == This patch prohibits performing of all set commands in SRIOV mode on sysfs level. It offers better error handling as calls that are not allowed will not be propagated further. == Test == Writing to any sysfs file in passthrough mode will succeed. Writing to any sysfs file in ONEVF mode will yield error: "calling process does not have sufficient permission to execute a command".
