[PATCH] acpi: strip compiler info in built-in DSDT if any

by Michael S. Tsirkin

IASL stores it's revision in each table header it generates. That's a problem since guests see a change each time they move between hypervisors. We generally fill our own info for tables, but we forgot to do this for the built-in DSDT. Signed-off-by: Michael S.

PXE boot ROM question

by Jonathan Sturges

Hi, I'm in the process of dusting off an old Geode GX1 thin client I have and upgrading it to coreboot v4. I had no problem building a new coreboot image (v4 is SO much easier than v2), but I'm having an issue with SeaBIOS and option ROMs. Since this is my first time working with SeaBIOS, I need a bit of help to bring this together. I built a PXE ROM for the onboard NIC, which is a NatSemi DP83815 (DEV/DID 100b/0020). I've tried both an iPXE image built from scratch, as well as a GPXE ROM from rom-o-matic. I added the ROM with cbfstool as documented at coreboot.org, and also added a bootorder file that lists the NIC first. However, when SeaBIOS calls the ROM, nothing seems to happen. See below, where it tries to boot from the ROM but fails almost immediately. It boots successfully from the local disk after the ROM returns. Any pointers as to what the issue is are appreciated.

[PATCH v7 0/3] seabios: load acpi tables from qemu

by Michael S. Tsirkin

This is the seabios code that adds support for loading acpi tables from QEMU. Changes from v6: - submission was botched, it didn't compile fix up patch biostables: support looking up RSDP no changes to other patches Changes from v5: - address Kevin's comments: move code to find rsdp to biostables.c scan for RSDP at 0x10 intervals Changes from v4: - address Kevin's comments: move loader to src/fw/ simplify some code drop some unused code chunks load from ROM even if !ACPI rename option to make it non ACPI specific Changes from v3: - updated to latest bits - add option to disable loading from QEMU Changes from v2: - addressed comments from Kevin: fixed coding style, minimized changes to existing code Changes from v1: - simplified linker interfaces along the lines suggested by Kevin - fixed lots of bugs Michael S.

[PATCH for 1.7] pc: disable pci-info

by Igor Mammedov

The BIOS that we ship in 1.7 does not use pci info from host and so far isn't going to use it. Taking in account problems it caused see 9604f70fdf and to avoid future incompatibility issues, it's safest to disable that interface by default for all machine types including 1.7 as it was never exposed/used by guest. And properly remove/cleanup it during 1.8 development cycle.

[PATCH] Convert op->drive_g from a 16bit pointer to a 32 bit "GLOBALFLAT" pointer.

by Kevin O'Connor

The "drive" structure is always malloc'ed and therefore always starts off described as a 32-bit "flat" pointer. Instead of switching to/from 16bit pointers, make all the code use the 32bit pointer. This eliminates the confusing 16/32 bit pointer switches. This patch also removes the "_g" suffixes on local variables in functions that are always called in 32bit mode.

qemu 1.7 & seabios -- release planning

by Gerd Hoffmann

Hi, It's probably going to be a bit tough this time. We are pretty late in the qemu 1.7 devel cycle, soft freeze today, and a big chunk of code (ahci-tables-from qemu) which needs seabios support[1] is just about to be pulled. That leaves only two weeks (with kvm forum in the middle!) until qemu 1.7 hard freeze with -rc0 (2013-10-29), which should ideally have a seabios update so it can be tested in the rc phase. There are two more interface updates (pass pcimem64-start address + e820 entries for ram regions) which would be good to get in while being at it. seabios patches are ready for the most part and just waiting for the qemu counterparts to be merged first. The timing constrains suggest we should tightly align the releases, with seabios releases being a bit earlier, i.e. something like this: (1) merge pending qemu patches (2) merge pending seabios patches (3) tag -rc0 seabios release [asap, no later than 2013-10-28] (4) merge seabios update into qemu (5) qemu hard freeze, -rc0 release with seabios update [2013-10-29] (6) seabios freeze in parallel with qemu hard freeze (7) apply seabios fixes if needed. (8) tag final seabios release [targeting qemu -rc2 or -rc3 date here] (9) merge seabios bugfix update into qemu Qemu 1.7 schedule is here: http://wiki.qemu.org/Planning/1.7 Comments? cheers, Gerd [1] Strictly speaking it isn't absolutely required, but would be very good to have.

[PATCH] vgahooks: add SM720 VGA BIOS hooks for WIN Enterprises MB-60470

by Jonathan A. Kollasch

Add vgahooks to support the SMI SM720 VGA BIOS used on the WIN Enterprises MB-60470. The response from smi_157f14() is necessary for the CRT output to turn on. The response from smi_157f02() is used to configure which connector(s) output is routed to. As I lack hardware to test LCD panel output, I've selected CRT-only output on the MB-60470 as this prevents the CRT output from being scaled to the resolution of the LCD panel.
