This is v8, rebased to avoid a conflict with 8d5d515a0fb ("build: chardev is only needed for softmmu targets"), which affected patch 2. Daniel and Laurent gave me acks for issuing a pull request touching their subsystems. The reasonable thing seemed to be to put those into the log for the signed tag itself. r~ The following changes since commit a4f667b6714916683408b983cfe0a615a725775f: Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20190521-3' into staging (2019-05-21 16:30:13 +0100) are available in the Git repository at: https://github.com/rth7680/qemu.git tags/pull-rng-20190522 for you to fetch changes up to 369fd5ca66810b2ddb16e23a497eabe59385eceb: target/i386: Implement CPUID_EXT_RDRAND (2019-05-22 12:38:54 -0400) ---------------------------------------------------------------- Introduce qemu_guest_getrandom. Use qemu_guest_getrandom in aspeed, nrf51, bcm2835, exynos4210 rng devices. Use qemu_guest_getrandom in target/ppc darn instruction. Support ARMv8.5-RNG extension. Support x86 RDRAND extension.
