Loongson SIMD Extension (LSX), Loongson Advanced SIMD Extension (LASX) and Loongson Binary Translation (LBT) features are defined in register CPUCFG2. Two kinds of LSX/LASX/LBT feature detection are added here, one is VCPU feature, and the other is VM feature. VCPU feature dection can only work with VCPU thread itself, and requires VCPU thread is created already. So LSX/LASX/LBT feature detection for VM is added also, it can be done even if VM is not created, and also can be done by any threads besides VCPU threads. Here ioctl command KVM_HAS_DEVICE_ATTR is added for VM, and macro KVM_LOONGARCH_VM_FEAT_CTRL is added to check supported feature. And five sub-features relative with LSX/LASX/LBT are added as following: KVM_LOONGARCH_VM_FEAT_LSX KVM_LOONGARCH_VM_FEAT_LASX KVM_LOONGARCH_VM_FEAT_X86BT KVM_LOONGARCH_VM_FEAT_ARMBT KVM_LOONGARCH_VM_FEAT_MIPSBT Signed-off-by: Bibo Mao <maobibo@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
