kernel/arch/arm64/kvm/trng.c, branch linux-6.2.y Hosts the 0x221E linux distro kernel. https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-6.2.y 2021-01-25T22:19:31Z KVM: arm64: Implement the TRNG hypervisor call 2021-01-25T22:19:31Z Ard Biesheuvel ardb@kernel.org 2021-01-06T10:34:53Z urn:sha1:a8e190cdae1bf8e9e490776b8179babc1962bb25 Provide a hypervisor implementation of the ARM architected TRNG firmware interface described in ARM spec DEN0098. All function IDs are implemented, including both 32-bit and 64-bit versions of the TRNG_RND service, which is the centerpiece of the API. The API is backed by the kernel's entropy pool only, to avoid guests draining more precious direct entropy sources.
