From 94f5da75db59d1337da27bcc8a219ca7de69b913 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 19 May 2020 22:04:00 +0100 Subject: lib/i915: Assume unknown hardware just works If we don't recognise the hardware, then it can't be any of the known broken HW where MI_STORE_DWORD_IMM either uses physical addressing or simply fails catastrophically. As it's not known to be broken, assume it just works.
