Yes, I am interested in the generation. Since DRM_IOCTL_I915_GETPARAM returns the pci_id, a common place to get the generation would be nice. Intel folks, where do you think would be the best place to put this (libdrm_intel or the kernel)??

It sounds like you're interested in the actual generation rather than
the exact device id, correct ?
If so an interface like [1] sounds be a better fit. I've poked Chris
about moving it to libdrm_intel so that others can also use it [2].
Guessing he did not have much time about that :-\
Thanks
