Many thx. Side note, while at it: I think this linux-drm patch from
Michał fell through the cracks, too:
https://lists.freedesktop.org/archives/intel-gfx/2016-February/087855.html

Whole story:  That libdrm patch you applied contained this line:

+#define PCI_CHIP_SKYLAKE_SRV_GT3 0x192D

This id for the Iris Graphics P555 is also present in Mesa master
i965(¹), but missing in Linux master afaics:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/include/drm/i915_pciids.h#n279
And it's not in drm-intel-next either afaics:
https://cgit.freedesktop.org/drm-intel/tree/include/drm/i915_pciids.h?h=drm-intel-next#n279

CU, knurd

(¹)
