TBH, I'm not sure it was the best idea to let it live or die on it's own when it now creates a build dependency for this series. > This is based on sha1 > 1ea6057 Mark Cave-Ayland "mac_newworld: change default NIC to sungem for > mac99 machine". Perhaps this is why it doesn't apply cleanly against qemu.git. Are there dependencies we need to wait for in the ppc tree as well? > Please comment. Thanks. Besides the build dependency on PCI_VENDOR_ID_NVIDIA, I also get this: .../qemu.git/hw/vfio/spapr.c: In function ‘vfio_spapr_create_window’: .../qemu.git/hw/vfio/spapr.c:212:9: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized] error_report("Failed to create a window, ret = %d (%m)", ret); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Is this series expected to go in through the ppc branch given the bulk of the changes are there? Thanks, Alex
