From 504d1eff4bd324915f5c44223ab03086b0cbbd2c Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sun, 16 Jul 2017 16:40:41 +0200 Subject: 3rdparty/lib{hwbase,gfxinit}: Update to latest master Simplifies our C interface function gma_gfxinit(), due to the following changes: * *libgfxinit* knows about the underlying PCI device now and can probe MMIO addresses by itself. * The framebuffer mapping is now completely handled inside the library where we validate that we neither overflow - the stolen memory, - the GTT address space, the GTT itself nor - the aperture window (i.e. resource2 of the PCI device) that we use to access the framebuffer. Other changes: * Fixes and a quirk for DP training. * Fix for DP-VGA adapters that report an analog display in EDID. * Fixes for Skylake support with coreboot. * DDI Buffer drive-strength configuration for Haswell, Broadwell and Skylake. * `gfx_test` can now be run from X windows (with glitches). * Compatibility with GCC 7 and SPARK GPL 2017. TEST=Booted lenovo/t420 and verified that everything works as usual.
