[PATCH] smm: ignore bits 16,18-31 of SMM revision ID
by Paolo Bonzini July 30, 2015

July 30, 2015

Bits 16-31 of the SMM revision ID are feature bits. We only need to check that SMBASE relocation is supported, but do not care about other features. In particular, this allows the SMM I/O instruction restart feature to be present.

[PATCH 1/3] ich9: add TCO interface emulation
by Paulo Alcantara July 2, 2015

July 2, 2015

This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.

[PATCH v3 2/2] Add multiboot support.
by Vladimir 'φ-coder/phcoder' Serbinenko June 1, 2015

June 1, 2015

From 7ecb31e60ca5cde8f7649414a0463ff70fbe2865 Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko <phcoder(a)gmail.com> Date: Mon, 18 May 2015 19:07:16 +0200 Subject: [PATCH 2/2] Add multiboot support. I've been successfully using SeaBIOS as secondary bootloader. In more details I have GRUB2-as-payload in flash together with coreboot. SeaBIOS binary is on the HDD and loaded by GRUB when needed. This has an unfortunate consequence that I have to keep vga oprom in flash even if usually I boot without it. This patches makes bios.bin.elf multiboot executable with files passed as modules. Example: menuentry "SeaBIOS (mb)" --unrestricted { root=ahci0,2 multiboot /bios.bin.elf module /vgabios_x230.rom name=pci8086,0166.rom } the parameter name= specifies under which name SeaBIOS will see it.

[PATCH] Ignore certain error when asserting physical presence
by Stefan Berger May 26, 2015

May 26, 2015

Some hardware TPMs do not support the assertion of physical presence via the command. Ignore the specific error code TPM_BAD_PARAMETER if we come across such a device.
