Subject: Re: [PATCH] drm/amdgpu: add ta firmware load in psp_v12_0 for renoir
[AMD Public Use]
Hi Alex,
psp_sw_fini() releases the ta firmware
[AMD Public Use]
We also need to release the firmware when the driver unloads or is that already handled in some common path?
From: changzhu <Changfeng.Zhu@xxxxxxx>
From: Changfeng <Changfeng.Zhu@xxxxxxx>
It needs to load renoir_ta firmware because hdcp is enabled by default
for renoir now. This can avoid error:DTM TA is not initialized
