Get rid of a compile time dprintf warning
by Dave Frodin 10 Jan '13

This patch gets rid of a compile time dprintf warning. A 'long int' was being passed to a '%d'.

[PATCH] esp: enable busmaster

[PATCH 00/20] q35 support patch series
by Gerd Hoffmann 27 Nov '12

27 Nov '12

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.
