Subject: [PATCH 34/34] drm/amdkfd: Add CONFIG_HSA_AMD_SVM
Date: Wed, 14 Apr 2021 21:23:37 -0400 [thread overview]
Message-ID: <20210415012337.1755-35-Felix.Kuehling@amd.com> (raw)
In-Reply-To: <20210415012337.1755-1-Felix.Kuehling@amd.com>
Control whether to build SVM support into amdgpu with a Kconfig option.
This makes it easier to disable it in production kernels if this new
feature causes problems in production environments.
Use "depends on" instead of "select" for DEVICE_PRIVATE, as is
recommended for visible options.
