Paolo Bonzini ef12ea629e LoongArch KVM changes for v6.7 ... Add LoongArch's KVM support. Loongson 3A5000/3A6000 supports hardware assisted virtualization. With cpu virtualization, there are separate hw-supported user mode and kernel mode in guest mode. With memory virtualization, there are two-level hw mmu table for guest mode and host mode. Also there is separate hw cpu timer with consant frequency in guest mode, so that vm can migrate between hosts with different freq. Currently, we are able to boot LoongArch Linux Guests. Few key aspects of KVM LoongArch added by this series are: 1. Enable kvm hardware function when kvm module is loaded. 2. Implement VM and vcpu related ioctl interface such as vcpu create, vcpu run etc. GET_ONE_REG/SET_ONE_REG ioctl commands are use to get general registers one by one. 3. Hardware access about MMU, timer and csr are emulated in kernel. 4. Hardwares such as mmio and iocsr device are emulated in user space such as IPI, irqchips, pci devices etc. -----BEGIN PGP SIGNATURE----- iQJKBAABCAA0FiEEzOlt8mkP+tbeiYy5AoYrw/LiJnoFAmUaKb4WHGNoZW5odWFj YWlAa2VybmVsLm9yZwAKCRAChivD8uImeuj+EACFIsWmHb8I3q4feviWBIdRcve7 xzpseO/r2Xfx5IdU6/iAKIW1YNVpHU3c8+nYS20K73uGJnMJnAZ/hmPFf+0pJ4AB qZL4aBClRynH4YsdGUeYwBfU7VMKg66ijiaZkqFEa7lSePA81gwYY2MYao58J7Gw qMe9IPnxcU/a+UqxTrFs2/G4aSb4SR0cp69GFSIGXZ7uKBc4LCMZ0ujzo/NY/V4G NkoJi8I85frF1OQbJaeJ/lGkC1Dx3Qbv7AbXYObA8K/ka1c5lr9RKraha2BOFPif mHYDa7lE6qj6e5LX9QVcpkuDnxs2yaA0Zny/p2I2o7AS0xUU/eFGGdnu1bkMqrsw 42ZuKL5Dtp/Wl5W2EEIkCVmZar+3UOeiWwGXPTk4A4fQHEGayXzJvrdUa/7f+O6Y JWYKSVjo6ZHg0ArKFtA13N54KximsrOKTpaB4fuUIP5SXMB/+JVn77/93Oyq6XSY 9+7yUTzjeMqz+4o8DLPhBIyJPvZ6cxAfx2i4htHiQg7e9ir0rZE3jsOtvJ2pgo3K 1QtGSJWH9dQMeOFnBfpDIvx3aDBcXPayXHNdaL3t/gCwJCpRuH1g6HeDTYXCJsQc qu6FDoeQn5+5IeEzoZawapQIJ2y7iXTk5SoysybKcKmnp8yYKB6olCqW8cxbWeMs HSqTUusPMsnJGlJMTw== =jaPm -----END PGP SIGNATURE----- Merge tag 'loongarch-kvm-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/chenhuacai/linux-loongson into HEAD LoongArch KVM changes for v6.7 Add LoongArch's KVM support.
