<pre>Lionel,
The skylake lars system I am using is GT1 only.
The reason why is from the below info:
localhost /sys/kernel/debug/dri/0 # cat i915_sseu_status
SSEU Device Info
Available Slice Total: 1
Available Subslice Total: 2
Available Subslice Per Slice: 2
Available EU Total: 12
Available EU Per Subslice: 6
Has Slice Power Gating: no
Has Subslice Power Gating: no
Has EU Power Gating: yes
SSEU Device Status
Enabled Slice Total: 1
Enabled Subslice Total: 2
Enabled Subslice Per Slice: 2
Enabled EU Total: 16
Enabled EU Per Subslice: 8
Confirmed with below mesa code as well which defined device info for skl_gt1:
static const struct gen_device_info gen_device_info_skl_gt1 = {
GEN9_FEATURES, .gt = 1,
.is_skylake = true,
.num_slices = 1,
.num_subslices = { 2, },
.num_eu_per_subslice = 6,
.l3_banks = 2,
.urb.size = 192,
};</pre>
