It's a Rockchip RK3399 board, essentially the same as a ROCKPro64=2E It wo= rks, but requires some tinkering (kernel patches to enable more devices)=2E It's okay if you just want a headless FreeBSD/aarch64 box to compile and t= est software on=2E Having two A72 cores is better than only having ultra lo= w power joke cores (A53), but the mixing of the cores (big=2ELITTLE) is "fu= n" =E2=80=93 FreeBSD's ULE scheduler is not really aware of it, so you can'= t tell it to, say, "fill up the fast cores first"=2E So you can cpuset your= compile job to the fast cores and not benefit from the A53 ones at all, or= not cpuset and see the A72s idle sometimes=2E So an RPi 4 (when supported)= would be better =E2=80=93 all 4 cores are fast cores! If you want to use an RK3399 device as a desktop/laptop=2E=2E use Linux=2E= You can run FreeBSD in KVM :) If you specifically want an aarch64 FBSD desktop because you're weird like= me=E2=80=A6 the only "affordable" option right now is the MACCHIATObin, an= d it's not super fast (funnily enough, same core configuration as an RPi4, = only a clock speed and memory advantage) and has a giant network interface = that's not supported by FreeBSD=2E But it runs upstream EDK2 (TianoCore) fi= rmware, with working PCIe under ACPI! SolidRun are working on a new device (HoneyComb LX2K) that's going to be m= ore powerful (NXP chip with 16 A72 cores, dual channel RAM, overclocking) a= nd with more PCIe lanes (8x slot + M=2E2 slot)=E2=80=A6 and another network= card FreeBSD does not have a driver for :D Hopefully PCIe under ACPI works= , they said they're working on ARM SBSA compliance, but some experts were s= keptical about that=2E I also hope the firmware will be open, but I don't t= hink they promised that yet=2E From owner-freebsd-arm@freebsd.org Wed Jul 10 11:49:13 2019 Return-Path: <owner-freebsd-arm@freebsd.org> Delivered-To: freebsd-arm@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id CDD3015D3C8F for <freebsd-arm@mailman.ysv.freebsd.org>;
