[Intel-gfx] [PATCH 02/12] intel: Introduce an drm_intel_device object
Damien Lespiau
damien.lespiau at intel.com
Thu Mar 5 08:20:10 PST 2015
The intention here is to:
- have a single object that represents a device
- reuse the kernel i915_pciids.h file so we only one place to update
and copy the file over.
- hide the various information about an intel device in that object
instead of having endless #define in intel_chipset.h. That can be
basic info like which gen are we talking about or, hopefully soon,
detailed information about the device (number of
slices/sub-slices/eus/...)
We'll start slowy by making this API an internal detail at the moment.
Maybe it can grow into something better.
