If something, the usual suspect being bios, access hw behind our back, don't let it slide into situation where normal register access will detect this and spit out a warn on into dmesg. On some bdw bioses this happens during igt/bat run always and as there is not much we can do about it, its better just to detect and flush this explicitly on resume and only print a debug message. v2: use DRM_DEBUG_DRIVER (Chris) v3: s/access/mmio, s/prior/prior to, s/dev/dev_priv Testcase: igt/pm_rpm/basic-rte Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Paulo Zanoni <przanoni@gmail.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> [Mika: fixed merge conflict] Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1450189512-30360-3-git-send-email-mika.kuoppala@intel.com |
