+## Tested systems
+
+The flexPTP Linux port has been tested on x86-based (64-bit generic PCs, Ubuntu 24.04, Ubuntu 24.10) and ARM-based (32-bit [BeagleBone Black Industrial](https://www.beagleboard.org/boards/beaglebone-black-industrial) SBC, Debian 12) Linux systems.
+
+All network interfaces supported by the kernel's PHC infrastructure can be used with flexPTP as well. The operation has been confirmed with the following Intel NICs:
+
+- Intel 82576
+- Intel I210
+- Intel I219-V
+- Intel E810
+
 ## Under the hood
 
 The porting layer used in this project is very much different compared to a conventional port supporting a specific  microcontroller. The [Network Stack Driver](https://epagris.github.io/flexPTP/porting.html#network-stack-driver) and the Hardware Port got unified into the single [nsd_linux.c](https://github.com/epagris/flexPTP/blob/master/src/flexptp/port/example_netstack_drivers/nsd_linux.c) source file. The port uses the Linux kernel's built-in PHC-adjustment functions and standard POSIX socket operations. Each major step is documented in the NSD source file.
