<pre>The log behaves as I expect. The change of cursors is being sent to the kernel,
but you observe that the updates do not occur.
Can you please try this kernel patch:
diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c
index 764467e..efcfd53 100644
--- a/drivers/gpu/drm/i915/i915_gem.c
+++ b/drivers/gpu/drm/i915/i915_gem.c
@@ -5055,6 +5055,7 @@ i915_gem_phys_pwrite(struct drm_device *dev,
return -EFAULT;
}
+ drm_clflush_virt_range(vaddr, args->size);
i915_gem_chipset_flush(dev);
return 0;
}
The other thing may be the two CRTCs using the same physical address. It's not
prohibited by the spec, but it may just be upsetting the hw?</pre>
