One inline comment. Can you also add other Coffee Lake pciids? 0x3E90, 12Eus, gt1 0x3E93, 12Eus, gt1 0x3E99, 12Eus, gt1 0x3EA1, 12Eus, gt1 0x3EA4, 12Eus, gt1

This bug exists long time. As I remember, I have post a patch for it, but seems missed. Can you send a new patch to fix it? _______________________________________________ Beignet mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/beignet
