[RFC PATCH v3 0/4] drm driver for VED in Intel GPU

[Yao Cheng]

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.

Yao Cheng (4):
[1/4] drm/i915: add i915_ved.c to setup bridge for VED
[2/4] drm/ipvr: drm driver for VED
[3/4] libdrm/ipvr: user mode helper for ipvr drm driver
[4/4] i-g-t: tests/drv_module_reload: add ipvr support
