[PATCH] tools/kconfig/{m,n}conf.c: Fix typo »This interface let*s*«
by Paul Menzel Oct. 3, 2013

Oct. 3, 2013

Date: Mon, 4 Mar 2013 12:56:56 +0100 When Kconfig was introduced in SeaBIOS with commit a4c5daf0e2545361fadcad3015e10f8b23e53926 Author: Kevin O'Connor <kevin(a)koconnor.net> Date: Mon Jan 24 22:13:58 2011 -0500 Initial commit of Kconfig build tool. this typo was copied from Kconfig in Linux v2.6.38-rc2. In the meantime Linux commit »kconfig: nconf: rewrite help texts« (0b616500) [1] rewrote the texts for `nconf.c` – which might be ported too to SeaBIOS – and the typo was fixed there. But it is still present in `mconf.c` as of Linux 3.8.

[PATCH v2 00/19] SeaBIOS as Compatibility Support Module for UEFI/OVMF
by David Woodhouse June 25, 2013

June 25, 2013

Changes from v1: - Make CONFIG_CSM a top-level build target in parallel with COREBOOT/QEMU. - More Kconfig cleanup. - Add generic find_pmtimer() function to find the pmtimer from ACPI tables. - Make Xen and coreboot builds both use find_pmtimer(). - Merge E820 table one entry at a time instead of wholesale copy. - Add pic_save_mask() and pic_restore_mask() functions. - Less intrusive size reduction for handle_post(). - Various other cleanups. -- David Woodhouse Open Source Technology Centre David.Woodhouse(a)intel.com Intel Corporation

[PATCH 0/2] accept MADT over fw_cfg
by Laszlo Ersek May 7, 2013

May 7, 2013

The first patch cleans up some field assignments in build_madt(). The second one handles the case when MADT is provided by qemu over fw_cfg. I'll soon post the qemu-side series as well. I cross-tested {patched, unpatched} qemu with {patched, unpatched} seabios. Inside a RHEL-6 guest I dumped the RSDT, DSDT, and APIC (MADT) in all four cases, and compared the results. Patched qemu with unpatched seabios don't play nicely together (two APIC (MADT) tables present). Otherwise everything seemed fine to me. The CPU topology was set with -smp 3,maxcpus=16,sockets=2,cores=4,threads=2 The table dumps / disassemblies are too big to include here, please find them at <http://people.redhat.com/~lersek/acpi_move/madt_tests.tar.gz>.
