Subject: [PATCH 06/34] drm/amdkfd: support larger svm range allocation
Date: Wed, 14 Apr 2021 21:23:09 -0400 [thread overview]
Message-ID: <20210415012337.1755-7-Felix.Kuehling@amd.com> (raw)
In-Reply-To: <20210415012337.1755-1-Felix.Kuehling@amd.com>
From: Philip Yang <Philip.Yang@amd.com>
For larger range allocation, if hmm_range_fault return -EBUSY, set retry
timeout based on 1 second for every 512MB, this is safe timeout value.
