Mark Johnston b9ef152bec vmm: Merge vmm_dev.c ... This file contains the vmm device file implementation. Most of this code is not machine-dependent and so shouldn't be duplicated this way. Move most of it into a generic dev/vmm/vmm_dev.c. This will make it easier to introduce a cdev-based interface for VM creation, which in turn makes it possible to implement support for running bhyve as an unprivileged user. Machine-dependent ioctls continue to be handled in machine-dependent code. To make the split a bit easier to handle, introduce a pair of tables which define MI and MD ioctls. Each table entry can set flags which determine which locks need to be held in order to execute the handler. vmmdev_ioctl() now looks up the ioctl in one of the tables, acquires locks and either handles the ioctl directly or calls vmmdev_machdep_ioctl() to handle it. No functional change intended. There is a lot of churn in this change but the underlying logic in the ioctl handlers is the same. For now, vmm_dev.h is still mostly separate, even though some parts could be merged in principle. This would involve changing include paths for userspace, though.
