The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=242cd60a0a670ff7cc446436bedd129fbdce062c commit 242cd60a0a670ff7cc446436bedd129fbdce062c Author: Milan Obuch <bsd@dino.sk> AuthorDate: 2022-04-02 16:53:37 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2022-04-03 15:28:37 +0000 cgem: Support building as a loadable kernel module For development, building a driver as kernel module is both convenient and a time saver (no need for reboot on some change, testing it requires just kldunload and kldload, a matter of seconds). For some special cases, it may be even desirable to postpone initializing the network interface after some action is done (loading a FPGA bitstream may be required for Zynq/ZynqMP based hardware as an example). Building is limited to ARM, ARM64 and RISC-V architectures (for Zynq, ZynqMP, PolarFire Soc based boards, and HiFive based boards are known to use CGEM at the moment).
