From 773488f3f7fc76ca252562435cb3a9f7abf64f5e Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Wed, 18 Oct 2017 12:27:25 -0500 Subject: soc/intel/broadwell: add support for Intel GMA OpRegion Add global/ACPI nvs variables required for IGD OpRegion. Add functions necessary to generate ACPI OpRegion, save the table address in ASLB, and restore table address upon S3 resume. Implementation largely based on existing Haswell/Lynxpoint code. Test: boot Windows 10 on google/lulu with Tianocore payload and GOP display init, observe display driver loaded and functional, display not black screen when resuming from S3 suspend.
