dmesg -w with drm.debug=0x5e after my patch in comment 10

this is the dmesg which opened drm.debug=0x5e, the kernel was built from latest drm_intel commit 0dfa1cee plus my patch in comment 10.

In this case, one internal 4K monitor plus 2 external 4k monitors which be attached after dell docking works well.

btw, all my test are in X modesetting.
