why do we need this variable ?
Hi Shashank,
If any error comes while the device is booting then amdgpu will start
unloading everything.
So I am using 'initialized' for unloading a driver successfully. This
variable is to identify that the driver is loaded or not.
I am not sure if I am getting this right. This variable is only
getting used in this patch here, just being set and reset.
How does this flag help us ? I guess if AMDGPU driver is getting
unloaded we already know that we can't set power profile.
We are setting "initialized = true" and checking in
amdgpu_workload_profile_fini() that 'initialized' is set or not set because
amdgpu_workload_profile_fini() is destroying mutex and same for delayed
work which I have implemented in patch 0003.
In the below error case where amdgpu_workload_profile_init() was not
called because psp firmware failed to load but amdgpu driver is
calling all unload function as well amdgpu_workload_profile_fini().
ThankYou
~Arvind

This is the below error for which the amdgpu driver is unloading when
it is not getting firmware.
