[PATCH 01/20] seabios: make mttr UC area setup dynamic
by Gerd Hoffmann 27 Nov '12

27 Nov '12

From: Jason Baron <jbaron(a)redhat.com> Set up the UC area of mtrr dynamically based on mtrr_base. This allows the bios to work for other chipsets that might want to set the mtrr. Since BUILD_MAX_HIGHMEM is no longer used we can remove the config parameter. This change reverses the order of pci_setup() and smm_init() with mtrr_setup().

Hi, Next round of the q35 patch series, rebased to master. Patches 1-6 carry the C code bits. They have been adapted to the recent changes in master. mcfg acpi table generator simply uses the q35 constants as suggested by Kevin. Otherwise unmodified. Patches 7+ carry the ACPI bits. First the original unmodified dsdt patches, then a bunch of cleanup patches on top of that which for the most part split sharable AML code into separate files. cheers, Gerd PS: Anthony just pulled the q35 patches into qemu/master.

[PATCH 2/2] floppy: Allow floppy code to be used with coreboot.
by Kevin O'Connor 26 Nov '12

26 Nov '12

Allow coreboot users to enable the floppy support (via CBFS files etc/floppy0 and etc/floppy1) on real hardware. It is unknown if the Bochs derived floppy controller support will work on real hardware, but this option will make it easier for those wishing to test.

[PATCH 1/2] floppy: Minor cleanup - reduce some cut-and-paste code.
by Kevin O'Connor 26 Nov '12

26 Nov '12

The diskette_param_table is a copy of diskette_param_table2 - just memcpy it at runtime instead of duplicating the configuration in the code. Also, setup the floppy interrupt vector in the floppy.c code instead of the post.c code.

[PATCH RfC 0/2] add q35 support
by Gerd Hoffmann 26 Nov '12

Hi, The q35 C code bits for review. The confusing mcfg acpi table code is largely rewritten, otherwise q35 initialization is almost unmodified.

I don't think it makes much sense to have a USB image that is that small. -Kevin
