[PATCH RFC 0/2] add remote-port protocol implementation

Posted by ruslichenko.r@gmail.com 1 day, 15 hours ago

This patch series implements simulation of processor peripherals using SystemC-based modules running outside QEMU.
The underlying mechanism for communication with external simulation environments from QEMU side is Remote Port socket based interface.

The simulation is provided by libSystemCTLM-SoC [1].

Originally implemented by Edgar Iglesias. The sources are now available at QEMU repo at AMD: https://github.com/Xilinx/qemu.

The implementation was checked on AWS Graviton 4 based metal instances with Renesas sourced peripherals (example link to follow).

There are number of modules which can be used including PCIe-based or MMIO based device.
The SMMU support for later are going to be implemented within further patches.
