SYNOPSIS

struct drm_i915_gem_object * gem_allocate_guc_obj(struct drm_device * dev, u32 size);

ARGUMENTS

dev

drm device

size

size of object

DESCRIPTION

This is a wrapper to create a gem obj. In order to use it inside GuC, the object needs to be pinned lifetime. Also we must pin it to gtt space other than [0, GUC_WOPCM_TOP) because this range is reserved inside GuC.

RETURN

A drm_i915_gem_object if successful, otherwise NULL.
