[Mesa-dev] fp/int64 on gen11/12?

[Brian Paul]

Another Intel question:  It looks like gen11/gen12 don't have fp/int64 
enabled in the Vulkan driver. From gen_device_info.c:

#define GEN11_FEATURES(_gt, _slices, _subslices, _l3) \
    GEN8_FEATURES,                                     \
    GEN11_HW_INFO,                                     \
    .has_64bit_float = false,                          \
    .has_64bit_int = false,
...

#define GEN12_FEATURES(_gt, _slices, _l3)                       \
    GEN8_FEATURES,                                               \
    GEN12_HW_INFO,                                               \
    .has_64bit_float = false,                                    \
    .has_64bit_int = false,

But gen8/9 do support it.  Is this a driver and/or hardware issue?
