This patchset fixes up macio/DBDMA to allow migration to succeed for Mac
machines while IDE/DMA requests are in-flight, and in conjunction with the
migration fixup patchset, enables me to successfully migrate live VMs
under TCG.
Migration was tested by running through a complete Darwin install whilst
issuing savevm/loadvm command pairs every minute or so in the monitor
with no visible ill-effects, and resulted in a bootable disk image.
Signed-off-by: Mark Cave-Ayland <address@hidden>
Mark Cave-Ayland (4):
macio: use the existing IDEDMA aiocb to hold the active DMA aiocb
macio: add dma_active to VMStateDescription
mac_dbdma: add DBDMA controller state to VMStateDescription
cuda: add missing fields to VMStateDescription
