From 963500fe0bd9c43623a4ce67a2b73c2a22480141 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sun, 29 Apr 2018 19:56:49 +0200 Subject: mb/gigabyte/ga-h61m-s2pv: Add new mainboard Tested with GRUB 2.02 as a payload, booting Arch Linux with latest kernel. This code is based on the output of autoport as well as existing ga-b75m-d3h and ga-b75m-d3v mainboards. Working: - Serial port I/O - S3 suspend/resume (broken with SeaBIOS 1.11.1) - USB ports and headers - Gigabit Ethernet - Integrated graphics (libgfxinit) - PCIe x16 graphics - PCIe x1 - SATA controller - Hardware Monitor - Fan Control (fancontrol on linux works well) - Native raminit (4+4GB, 4+2GB, 2+2GB, DDR3-1333) - Native graphics init with libgfxinit - flashrom, using the internal programmer. Tested with coreboot, as well as with the vendor firmware. Backup chip is untested. - NVRAM settings. Only `gfx_uma_size` and `debug_level` have been tested with values different from the default. Untested: - VGA BIOS for integrated graphics init - DVI port. It can detect a "fake" display, that is, an EEPROM connected to the DVI port. - PS/2 ports - Audio: Only rear output (green) has been tested. - EHCI debug. - Parallel port - Non-Linux OSes - ACPI thermal zone and fan control (probably not working) Not working: - SATA devices with Tianocore (payload issue) - PCIe to PCI bridge. It seems to be poorly supported on Linux, it lacks a public datasheet and vendor BIOS behaves in the same way: The bridge and the devices behind it appear, but drivers fail to find devices attached to the bridge.
