There's a corner case: When want to get CPUID.01H:EDX value, may have the following code snippet: uint32_t unused,edx; cpuid_subleaf(0x1U, 0x0U, &unused, &unused, &unused, &edx); while in cpuid_subleaf: *eax = leaf; *ecx = subleaf; eax and ecx point to the same location, When deep into asm_cpuid, it's input value will be 0x0U and 0x0U. but the expected input value is 0x1U and 0x0U. This case will return CPUID.00H:EDX, which is the wrong answer. Tracked-On: #4526 Signed-off-by: Junming Liu <junming.liu@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
ACRN Hypervisor ############### The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the "ACRN Device Model". The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on the bare-metal hardware, and is suitable for a variety of IoT and embedded device solutions. The ACRN hypervisor addresses the gap that currently exists between datacenter hypervisors, and hard partitioning hypervisors. The ACRN hypervisor architecture partitions the system into different functional domains, with carefully selected guest OS sharing optimizations for IoT and embedded devices. You can find out more about Project ACRN on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
