2016-11-28	drm/msm/rd: support for 64b iova	Rob Clark	1	-2/+2
	For backwards compat, the rd format puts the high 32b after the size field in the GPUADDR packet. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-08-07	gpu: use %pd	Al Viro	1	-2/+2

2016-07-16	drm/msm: return -EFAULT instead of bytes remaining	Dan Carpenter	1	-2/+3
	copy_to/from_user returns the number of bytes remaining to be copied but we want to return -EFAULT. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-07-16	drm/msm/rd: add module param to dump all bo's	Rob Clark	1	-7/+31
	By default, if using $debugfs/.../rd to log cmdstream, only the cmdstream buffers themselves are logged. But in some cases we want to capture other buffers in the submit (to see VBO's or shaders). So add a mod-param knob to control this. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-07-16	drm/msm/rd: split out snapshot_buf helper	Rob Clark	1	-14/+22
	(reduce the noise in next patch) Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-07-16	drm/msm: change gem->vmap() to get/put	Rob Clark	1	-1/+3
	Before we can add vmap shrinking, we really need to know which vmap'ings are currently being used. So switch to get/put interface. Stubbed put fxns for now. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-06-04	drm/msm: deal with exhausted vmap space better	Rob Clark	1	-0/+3
	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>
2016-05-08	drm/msm: 'struct fence' conversion	Rob Clark	1	-1/+1
	Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-06-02	drm/msm: add rd logging debugfs	Rob Clark	1	-0/+337
	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.
