Subject: [PATCH 08/10] drm/amdkfd: add invalid pages debug at vram migration
Date: Thu, 27 May 2021 16:56:04 -0400 [thread overview]
Message-ID: <20210527205606.2660-8-Felix.Kuehling@amd.com> (raw)
In-Reply-To: <20210527205606.2660-1-Felix.Kuehling@amd.com>
From: Alex Sierra <alex.sierra@amd.com>
This is for debug purposes only.
It conditionally generates partial migrations to test mixed
CPU/GPU memory domain pages in a prange easily.
