Deduplicate much of this codeand move it into sys/dev/vmm/vmm_mem.c.To avoid exporting struct vm outside of machdep vmm.c, add a newstruct vm_mem to contain the memory segment descriptors, and add avm_mem() accessor, akin to vm_vmspace(). This way vmm_mem.c canimplement its routines without needing to see the layout of struct vm.The handling of the per-VM vmspace is also duplicated but will be movedto vmm_mem.c in a follow-up patch.On amd64, move the ppt_is_mmio() check out of vm_mem_allocated() to keepthe code MI, as PPT is only implemented on amd64. There are only acouple of callers, so this is not unreasonable.No functional change intended.Reviewed by: jhbDifferential Revision: https://reviews.freebsd.org/D48270 List of files: /freebsd/sys/modules/vmm/Makefile Tue, 18 Feb 2025 16:53:16 +0100 Mark Johnston <markj@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/vmm/Makefile#fbacadf103dc81cea0f233f11adb73ef43ee4a75 vmm: Add vmm_fence.c to SRCS for vmm.ko on riscvFixes: 8f6b66a9d3f2 ("riscv vmm: implement SBI RFNC extension.")

Use itfor timer interrupt only for now, but later we can extend to store allpending interrupts (Timer, IPI and External).With this I'm able to boot FreeBSD (SMP) guest on HiFive Premier P550,which is the first real hardware with RISC-V 'H'-spec included.Differential Revision: https://reviews.freebsd.org/D48133 List of files: /freebsd/sys/modules/vmm/Makefile Thu, 02 Jan 2025 16:42:34 +0100 Ruslan Bukin <br@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/vmm/Makefile#0a897e67548156ed731dae68eafd21728894ef91 riscv: Add support for building vmm as a kernel module- Update sys/modules/vmm/Makefile.- Add some required symbol definitions.- Hook up vmm in sys/modules/Makefile.Reviewed by: brDifferential Revision: https://reviews.freebsd.org/D47477 List of files: /freebsd/sys/modules/vmm/Makefile Wed, 13 Nov 2024 15:09:58 +0100 Mark Johnston <markj@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/vmm/Makefile#f95acbd89d594b5932197679d94d2ba23c1d0331 vmm: Rename the amdiommu driver to amdviiommuTo avoid a conflict with the new amdiommu driver imported recently.Fixes: 0f5116d7efe3 ("AMD IOMMU driver")Reviewed by: kibDifferential Revision: https://reviews.freebsd.org/D47415 List of files: /freebsd/sys/modules/vmm/Makefile Mon, 04 Nov 2024 15:44:19 +0100 Mark Johnston <markj@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/vmm/Makefile#b9ef152bec6cff4cd82b68921f631bd6efb24ae6 vmm: Merge vmm_dev.cThis file contains the vmm device file implementation. Most of thiscode 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 iteasier to introduce a cdev-based interface for VM creation, which inturn makes it possible to implement support for running bhyve as anunprivileged user.Machine-dependent ioctls continue to be handled in machine-dependentcode. To make the split a bit easier to handle, introduce a pair oftables which define MI and MD ioctls. Each table entry can set flagswhich determine which locks need to be held in order to execute thehandler. vmmdev_ioctl() now looks up the ioctl in one of the tables,acquires locks and either handles the ioctl directly or callsvmmdev_machdep_ioctl() to handle it.No functional change intended. There is a lot of churn in this changebut the underlying logic in the ioctl handlers is the same. For now,vmm_dev.h is still mostly separate, even though some parts could bemerged in principle. This would involve changing include paths foruserspace, though.Reviewed by: corvink, jhbDifferential Revision: https://reviews.freebsd.org/D46431 List of files: /freebsd/sys/modules/vmm/Makefile Mon, 26 Aug 2024 20:41:39 +0200 Mark Johnston <markj@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/vmm/Makefile#93e81baa1c1baccf4eca9e3dbfe5ac9378e9623a vmm: Move duplicated stats code into a generic fileThere is a small difference between the arm64 and amd64 implementations:the latter makes use of a "scope" to exclude AMD-specific stats on Intelsystems and vice-versa.
