Subject: [PATCH 2/2] drm/amdkfd: set new unregistered range accessible by GPU
Date: Wed, 5 May 2021 13:56:17 -0400 [thread overview]
Message-ID: <20210505175617.30404-2-Philip.Yang@amd.com> (raw)
In-Reply-To: <20210505175617.30404-1-Philip.Yang@amd.com>
GPU retry vm fault on unregistered address, new range is created to
recover the retry vm fault. Instead of setting new range perferred_loc
to GPU, add GPU to new range access_bitmap, to be able to update GPU
page table after new range migrate to VRAM. The new range preferred_loc
is default value KFD_IOCTL_SVM_LOCATION_UNDEFINED.
Correct one typo.
