I have a quad core 64 bit ARM system (SoftIron Overdrive 1000). I am wonde= ring what faster 64 bit ARM systems exist and which of them work, or almost= work, with FreeBSD. Excluding 4 core and below systems regardless of performance, and also excl= uding cloud-only hardware, I made the list below. Did I miss anything or i= naccurately describe support? Two RK3399 based systems, 2 A-72 + 4 A-53: RockPro64 (http://www.pine64.com= /) and ROCK Pi 4 (http://radxa.com). I can't use the RockPro64 due to the = 1.5 MBps serial port. Apparently it works or almost works with some specia= l handling if your serial interface can count to 1,500,000. The ROCK Pi 4 = is in crochet so it must work... right? Does it have a reasonable console = port bit rate? SoftIron Overdrive 3000, 8 A-53 cores. No longer available. One LX2160A based system, 16 A-72 cores: HoneyComb LX2K (https://www.solid-= run.com/nxp-lx2160a-family/honeycomb-workstation/). I see relevant files i= n sys/gnu/dts/arm64/freescale but nothing outside of these files imported f= rom Linux. It's not mentioned on https://wiki.freebsd.org/arm64. My guess= is that means FreeBSD does not run. Is it a little job or a big one? SC2A11, 24 A-53 cores at 1 GHz: SynQuacer (https://www.96boards.org/product= /developerbox/). I don't see any evidence of SC2A11 support in the kernel= tree or on https://wiki.freebsd.org/arm64. My guess is that means FreeBSD= does not run. ThunderX in various forms, rack mount or workstation. Nice specs and appar= ently supported but the two American system builders don't seem interested = in selling me one. ThunderX2. Great specs and apparently mostly supported but rather expensiv= e.. (Honorable mention to Banana PI M3 with 8 cores, but 32 bits only.)=
