drm/ipvr is a new GEM driver for VED (PowerVR's VPU integrated in Intel GPU), which extends video decoding capability. Two new Kconfig added for building ipvr driver: CONFIG_DRM_IPVR: Build option for ipvr module CONFIG_DRM_IPVR_EC: Experimental feature of error concealment
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/decode test are 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.
