It seems my GM45 is Gen 4 (a bit older...) but at least it seems that is
supposed to be supported.
static const struct intel_device_info gm45_info = {
GEN4_FEATURES,
PLATFORM(INTEL_GM45),
.is_mobile = 1,
.display.has_fbc = 1,
.display.supports_tv = 1,
.engine_mask = BIT(RCS0) | BIT(VCS0),
.gpu_reset_clobbers_display = false,
};
I will check
https://github.com/freebsd/drm-kmod/blob/master/drivers/gpu/drm/i915/i915_pci.c
whco does show some differences in the GEN4_FEATURES macro. The first
thing I checked was however some completely new field, so that would
probably be irrelevant. Still, there may be hope...
