In commit 9d0498a2bf7455159b317f19531a3e5db2ecc9c4 20ms waits were converted into vblank waits. One of these caused tearing, mode detection and redraw issues on an EeePC 900 with a more recent intel userspace ( http://lkml.org/lkml/2010/8/23/432 ). Restoring the 20ms wait resolves the issue. --- drivers/gpu/drm/i915/intel_display.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 23157e1..116d938 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -4539,7 +4539,7 @@ struct drm_crtc *intel_get_load_detect_pipe(struct intel_encoder *intel_encoder, encoder_funcs->commit(encoder); } /* let the connector get through one full cycle before testing */ - intel_wait_for_vblank(dev, intel_crtc->pipe); + msleep(20); return crtc; } -- 1.7.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
