This series adds RTC device to QEMU RISC-V virt machine. We have selected Goldfish RTC device model for this. It's a pretty simple synthetic device with few MMIO registers and no dependency external clock. The driver for Goldfish RTC is already available in Linux so we just need to enable it in Kconfig for RISCV and also update Linux defconfigs.
We have tested this series with Linux-5.3 plus defconfig changes available in 'goldfish_rtc_v1' branch of: https://github.com/avpatel/linux.git Changes since v1: - Removed redundant object properties from Goldfish RTC emulation - Added vmstate for Goldfish RTC Anup Patel (2): hw: timer: Add Goldfish RTC device riscv: virt: Use Goldfish RTC device hw/riscv/Kconfig | 1 + hw/riscv/virt.c | 15 ++ hw/timer/Kconfig | 3 + hw/timer/Makefile.objs | 1 + hw/timer/goldfish_rtc.c | 278 ++++++++++++++++++++++++++++++++ include/hw/riscv/virt.h | 2 + include/hw/timer/goldfish_rtc.h | 46 ++++++ 7 files changed, 346 insertions(+) create mode 100644 hw/timer/goldfish_rtc.c create mode 100644 include/hw/timer/goldfish_rtc.h -- 2.17.1
