This repository contains Renesas R-Car Gen4-specific Yocto layers for Xen Troops distro. Some layers in this repository are product-independent. They provide common facilities that may be used by any xt-based product that runs on Renesas Gen4-based platforms.

Those layers may be added and used manually, but they were written with Moulin build system, as Moulin-based project files provide correct entries in local.conf

This is a release 1.0 of the Xen-based development product for the S4 Spider board.

This release provides the following features:

• Xen build compatible with S4 SoC
• Thin Dom0
• Driver domain (DomD), which has access to all available hardware
• Optional generic domain (DomU)
• Support for OP-TEE in virtualization mode
• ICCOM partitioning demo (proprietary components are required to test the feature)
• R-Switch VMQ: R-Switch virtualization feature
• R-Switch VMQ TSN: R-Switch TSN pass-through feature
• R-Switch L3 routing offload (including VLAN routes)
• R-Switch traffic control offload
• R-Switch offloaded IPS/IDS Snort support
• Disabling L3 HW forwarding respectively to /proc/sys/net/ipv4/ip_forward value
• Disabling/enabling L3 offload via sysfs file
• Virtualized OP-TEE support
• PCIe SR-IOV support

The following HW modules were tested and are confirmed to work:

• Serial console (HSCIF)
• IPMMUs
• R-Switch
• eMMC
• PCIe with ITS (but there is a running issue with MSI interrupts that sometimes do not work)

At least IPL 0.5.0 is required for normal operation. Release was tested with IPL 3.6.0. User is required to flash ARM TF (bl31-spider.srec) and OP-TEE (tee-spider.srec) provided by the build to ensure that Xen and DomD/DomU will work correctly.

• Virtualization
• TC and L3 offload
