Subject: | [Qemu-devel] [PATCH 0/2] fw_cfg: Implement fast "blit" operation for rapidly copying in kernel, initrd [etc] into the guest |

These two patches implement a faster way to copy the kernel and initrd data into the guest. The guest can set up a blit address and then issue a blit command in order to tell qemu to copy the whole of the configuration data into the predefined area of memory. This saves a couple of seconds of boot time when you have very large initrd images.
