Rob Clark	69a834c28f	drm/msm: deal with exhausted vmap space better ... Some, but not all, callers of obj->vmap() would check if return IS_ERR(). So let's actually return an error if vmap() fails. And fixup the call-sites that were not handling this properly. Signed-off-by: Rob Clark <robdclark@gmail.com>	2016-06-04 14:45:48 -04:00

Rob Clark	a7d3c9509b	drm/msm: add rd logging debugfs ... To ease debugging, add debugfs file which can be cat/tail'd to log submits, along with fence #. If GPU hangs, you can look at 'gpu' debugfs file to find last completed fence and current register state, and compare with logged rd file to narrow down the DRAW_INDX which triggered the GPU hang.
