Tested on a Dell Pro Max 16 (Arrow Lake-P) with Debian 7.2.6 and a Dell WD19DC dock with two MST sinks, i915 driving the dock over TBT-alt. Before the patch, every DPMS wake showed REMOTE_DPCD_READ BAD_PARAM NAKs on the empty downstream port. With the patch there were none across three DPMS off/on cycles. Both sinks were enumerated and lit up normally. The separate black screen after a long DPMS off is not affected by this patch. It is tracked in drm/i915/kernel#16901. -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEfCO4BD5l0pgKIbbiWJ8D8BulUDgFAmrN0bMACgkQWJ8D8Bul UDixdw//Vwdq5quU2oGIGXJU1YSMbBKEjxkqaRhBR/QiEsy93lwIlnps2UT8fwh3 EmeyaM+htA1kBzPsD8CZEdUIHDoo7U6lIDEBNeVFAkTjcg77NxIngsZ1ooqsTkcz OuZGNVzCgmkqk045vcCoqXdqDUn+KFC68WtiSvOUtgGkeFtnsew2LPN3Vz2NA+xi QzhKJv+QtpJJYgMQUfMZeRKR48IO9wlKYD3zSQW7g94Sh61Y+quVYaGaz7j5pIGo PQ/AZPCa2iATbBnl29KaTOClMvRAEZ+lXhoZ6FpbBsZflO5Rqf8EH+lyR6J3rbgu xVJ+Zm+xvEYnYVtAnVtr8uTHY23qQV4i/iYK/E0/CbeJUzELynF5Svz6WQL/Oqyc F1fjmNrLBklmeeCZnlAveV+AX9OKq+1xzGizeKexu88x3jJAihfMbojdgejl6rke P+0KB1w1CKAFHXmB9/dg1cfy1YJ9j0daMv64uCv7DlioWHFz2qMVX2A+6MRqwzDR vGCfJwds+f6opnpvODW/SizUd0bMS1FKqY26gCX8Bmr4DaIGUYjzOqq1H1EHbNtp S0ul/bqDaIPZPzP3oyRDz/XxLzWn2iGgMiBIRT5fQg5K+6H0/1AQ53PaCmm3809X mU60tVwTqbNeHetSdMARfrr8rudhjksChNxQQEeMAlmWFpXaUQ0= =Mkwe -----END PGP SIGNATURE-----
