[AMD Official Use Only - Internal Distribution Only] Reviewed-by: Le Ma <Le.Ma@amd.com> Regards, Ma Le -----Original Message----- From: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Sent: Thursday, December 12, 2019 4:39 AM To: dri-devel@lists.freedesktop.org; amd-gfx@lists.freedesktop.org Cc: Deucher, Alexander <Alexander.Deucher@amd.com>; Ma, Le <Le.Ma@amd.com>; Zhang, Hawking <Hawking.Zhang@amd.com>; Quan, Evan <Evan.Quan@amd.com>; Grodzovsky, Andrey <Andrey.Grodzovsky@amd.com> Subject: [RESEND PATCH 5/5] drm/amdgpu: Switch from system_highpri_wq to system_unbound_wq This is to avoid queueing jobs to same CPU during XGMI hive reset because there is a strict timeline for when the reset commands must reach all the GPUs in the hive.

This is to avoid queueing jobs to same CPU during XGMI hive reset because there is a strict timeline for when the reset commands must reach all the GPUs in the hive.
