<span class="quote">> I've been running with the workaround:

What is the correct format for setting those values? That's what I see there
now:
for plane in pri cur spr; do cat
/sys/kernel/debug/dri/0/i915_${plane}_wm_latency; done
WM0 2 (2.0 usec)
WM1 19 (19.0 usec)
WM2 28 (28.0 usec)
WM3 32 (32.0 usec)
WM4 63 (63.0 usec)
WM5 77 (77.0 usec)
WM6 83 (83.0 usec)
WM7 99 (99.0 usec)
WM0 2 (2.0 usec)
WM1 19 (19.0 usec)
WM2 28 (28.0 usec)
WM3 32 (32.0 usec)
WM4 63 (63.0 usec)
WM5 77 (77.0 usec)
WM6 83 (83.0 usec)
WM7 99 (99.0 usec)
WM0 2 (2.0 usec)
WM1 19 (19.0 usec)
WM2 28 (28.0 usec)
WM3 32 (32.0 usec)
WM4 63 (63.0 usec)
WM5 77 (77.0 usec)
WM6 83 (83.0 usec)
WM7 99 (99.0 usec)
That doesn't match the format in your example above.</pre>
