Subject: [PATCH 2/2] drm/amdkfd: unregistered range accessible by all GPUs
Date: Fri, 7 May 2021 15:07:04 -0400 [thread overview]
Message-ID: <20210507190704.7682-1-Philip.Yang@amd.com> (raw)
In-Reply-To: <20210505175617.30404-2-Philip.Yang@amd.com>
New range is created to recover retry vm fault, set all GPUs have access
to the range. The new range preferred_loc is default value
KFD_IOCTL_SVM_LOCATION_UNDEFINED.
Correct one typo.
