> drm/ipvr is a new GEM driver for VED (PowerVR's VPU integrated in Intel
> GPU), which extends video capability.
> A new Kconfig added for building ipvr driver:

>   CONFIG_DRM_IPVR: Build option for ipvr module

> The driver name "ipvr" means the PowerVR's core wrapped by Intel. The
> PowerVR VPUs are also integrated by non-i915 platforms such as GMA500, so
> we keep ipvr driver and i915 driver separated and independent to each other.
> To achieve this we do the minimum change in i915: i915_ved.c added for
> setting up the bridge between VED and i915, kerneldoc also updated.
> 
> User mode drm helper "libdrm_ipvr.so" and simple ioctl/execute test is
> included.
> 
> one test script "drv_module_reload" in i-g-t also updated to support ipvr
> loading and unloading. Due to restriction in Linux platform device model, we
> have to manually unload ipvr before unloading i915.
