[AMD Official Use Only - Internal Distribution Only] Hello GuChun,
I have updated the patch with your suggestion, and added back in the delay. I can potentially investigate its removal in another patch Thank you, John Clements From: Chen, Guchun <guchun.c...@amd.com> Sent: Friday, January 3, 2020 3:44 PM To: Clements, John <john.cleme...@amd.com>; Zhang, Hawking <hawking.zh...@amd.com>; amd-gfx@lists.freedesktop.org Subject: RE: [PATCH] drm/amdgpu: added function to wait for PSP BL availability [AMD Official Use Only - Internal Distribution Only] - /* there might be handshake issue with hardware which needs delay */ - mdelay(20); To be safety, I don't think we should remove this delay. And this actually do nothing with the code refine in this patch.
