From c936843f06ee4acfe91c2ef2909a2b46eb63c14a Mon Sep 17 00:00:00 2001 From: Oleg Vasilev Date: Thu, 13 Jun 2019 15:18:02 +0300 Subject: [PATCH] drm/vkms: add crc sources list Other drivers are able to list crc sources when accessing /sys/kernel/debug/dri/.../crtc-0/crc/control Even though VKMS now supports only 'auto' mode, it is more consistent to have the list available to the userspace.
