drm/etnaviv: call correct function when trying to vmap a DMABUF

2016-01-26T17:54:01+00:00

When trying to get the vmap address of an imported buffer, we must
call into the appropriate helper function, to allow the exporter to
establish the vmap, instead of trying to vmap the buffer on our own.

Add an indirection through etnaviv_gem_ops to allow the correct
implementation to be called.

drm/etnaviv: rename etnaviv_gem_vaddr to etnaviv_gem_vmap

2016-01-26T17:54:01+00:00

This function follows the semantics of vmap() by returning
NULL in case of an error. To make things less confusing
rename it to make make both functions more closely related.

drm/etnaviv: fix get pages error path in etnaviv_gem_vaddr

2016-01-26T17:54:00+00:00

In case that etnaviv_gem_get_pages is unable to get the required
pages the object mutex needs to be unlocked. Also return NULL in
this case instead of propagating the error, as callers of this
function might not be prepared to handle a pointer error, but
expect this call to follow the semantics of a plain vmap to return
NULL in case of an error.

drm/etnaviv: ignore VG GPUs with FE2.0

2016-01-26T17:53:27+00:00

Ignore GPUs with a 2.0 front end.  These have a different register
layout for the front end, which provokes imprecise aborts from the
register accesses in the 'gpu' debugfs file.
