This allows us to run hardware-accelerated VMs on Intel CPUs. Overall this implementation is fast and reliable, I am able to run NetBSD VMs with many VCPUs on a quad-core Intel i5. NVMM-Intel applies several optimizations already present in NVMM-AMD, and has a code structure similar to it. No change was needed in the NVMM MI frontend, or in libnvmm. Some differences exist against AMD: - On Intel the ASID space is big, so we don't fall back to a shared ASID when there are more VCPUs executing than available ASIDs in the host, contrary to AMD. There are enough ASIDs for the maximum number of VCPUs supported by NVMM. - On Intel there are two TLBs we need to take care of, one for the host (EPT) and one for the guest (VPID). Changes in EPT paging flush the host TLB, changes to the guest mode flush the guest TLB. - On Intel there is no easy way to set/fetch the VTPR, so we intercept reads/writes to CR8 and maintain a software TPR, that we give to the virtualizer as if it was the effective TPR in the guest. - On Intel, because of SVS, the host CR4 and LSTAR are not static, so we're forced to save them on each VMENTRY. - There is extra Intel weirdness we need to take care of, for example the reserved bits in CR0 and CR4 when accesses trap. While this implementation is functional and can already run many OSes, we likely have a problem on 32bit-PAE guests, because they require special care on Intel CPUs, and currently we don't handle that correctly; such guests may misbehave for now (without altering the host stability). I expect to fix that soon. @ text @d1 1 a1 1 # $NetBSD: Makefile,v 1.1 2018/11/07 07:43:08 maxv Exp $ d20 2 @ 1.1 log @Add NVMM - for NetBSD Virtual Machine Monitor -, a kernel driver that provides support for hardware-accelerated virtualization on NetBSD. It is made of an MI frontend, to which MD backends can be plugged. One MD backend is implemented, x86-SVM, for x86 AMD CPUs. We install /usr/include/dev/nvmm/nvmm.h /usr/include/dev/nvmm/nvmm_ioctl.h /usr/include/dev/nvmm/{arch}/nvmm_{arch}.h And the kernel module. For now, the only architecture where we do that is amd64 (arch=x86). NVMM is not enabled by default in amd64-GENERIC, but is instead easily modloadable. Sent to tech-kern@@ a month ago. Validated with kASan, and optimized with tprof. @ text @d1 1 a1 1 # $NetBSD: Makefile,v 1.1 2018/11/05 00:00:00 maxv Exp $ d17 1 @ 1.1.2.1 log @file Makefile was added on branch pgoyette-compat on 2018-11-26 01:52:50 +0000 @ text @d1 19 @ 1.1.2.2 log @Sync with HEAD, resolve a couple of conflicts @ text @a0 19 # $NetBSD: Makefile,v 1.1 2018/11/07 07:43:08 maxv Exp $ .include "../Makefile.inc" .include "../Makefile.assym" CPPFLAGS+= .PATH: ${S}/dev/nvmm .PATH: ${S}/dev/nvmm/x86 KMOD= nvmm IOCONF= nvmm.ioconf SRCS= nvmm.c .if ${MACHINE_ARCH} == "x86_64" SRCS+= nvmm_x86_svm.c nvmm_x86_svmfunc.S .endif .include @
