Red Hat Enterprise Linux for ARM arrives after seven years of development

I'm asking this half for me, half for the thread - does this mean RHEL on Raspberry Pi?

thanks.

AFAIK Pi 3 supports aarch64, so ... maybe? But AFAIK RHEL is probably targeting commercial servers first. But maybe a CentOS/SL for Pi 3 wouldn't be out of the question. The tricky bit is that Redhat probably doesn't have a market for creating and supporting the Pi 3 boot image. But they've done all the legwork for getting aarch64 support in their distro, so that could be reaped in CentOS/SL once you combine it w/a bootloader.

Having tested this, Debian and Ubuntu on a RPi2, I prefer Ubuntu for the packages available.

Correction, Ubuntu's official releases only support RPi2 http://cdimage.ubuntu.com/ubuntu/releases/17.10/release/

RHEL for ARM only runs on 64 bit ARM server hardware which supports UEFI and ACPI. Things like the Cavium ThunderX/X2, Qualcomm Centriq/Amberwing, HPE Apollo 70, Gigabyte MP30.

Fairly recent u-boot provides some UEFI APIs, not sure if enough to run RHEL, and as far as I know no ACPI at all. However in general terms RHEL for ARM isn't going to run on RPi-style hardware. (CentOS is quite different, they have a team taking the RHEL work and targeting cheaper hardware).

RHEL requires 64k base page size, which AFAIK the RPi3 doesn’t support. You can run Fedora and CentOS, though.

It’s only compiled for server SOCs I don’t see any indication that raspberry pi is tested or even supported . Not sure if you would want it even if it worked since it’s probably too much for your board .

There seems to be a giant gap between low cost ARM boards and server ARM boards. I think a moderately fast, yet low power ARM server would be interesting for things like a private cloud. The cheap ARM offerings are usually very limited in terms of RAM (2GB max) with no option to expand it.

Right now this market is (under-)served by some Intel Atom boards.

SoftIron.com. Cheapest option (OverDrive 1000) is $599.

https://www.solid-run.com/marvell-armada-family/armada-8040-... - $369. You can get it in a case too (https://www.solid-run.com/clearcloud-cloud-iot-core/)

https://www.phoenicselectronics.com will sell you a Gigabyte MT30-GS2 (Cavium ThunderX 32-core) 1U system for around $2k. If you want to provide your own ATX case - much less.

Gigabyte XGene-1 designs based on MP30-AR0 in 1U are literally $1k. http://www.nextwarehouse.com/item/?2465024_g10e

Agreed, it would be nice to see an "inexpensive" ARM platform that could include 8-16GB or so of memory.

Possibly this board (one day ...)

https://www.cnx-software.com/2017/09/24/gigabyte-synquacer-9... https://www.socionext.com/cn/pr/sn_pr20170922_01e.pdf

It has 24 low-end 64 bit cores, and up to 64 GB of RAM, dual ethernet, PCIe, ...

It's a bit of an odd board because those cores will be very slow, and I guess they're hoping to make up for it by having lots and lots of them. That didn't (IMHO) work well for the Cavium ThunderX, but I guess it will come down to price (supposedly "under $1000" which is many times more than an RPi, and many times less than an Amberwing).

And a pcie bus.

Marvell MacchiatoBIN, Overdrive 3000, Gigabyte MT30-GS2 (ThunderX), Gigabyte R120-P31 (X-Gene1)

How does ARM compare to Intel or AMD from a "cost per power" perspective (meaning, if ARM is twice weaker then AMD, is it less than 50% as expensive?)

Qualcomm are claiming great things for their Centriq processors.

[Qualcomm] says that the 48-core Centriq 2460 offers a 4x uplift in performance-per-dollar and a 45 percent performance-per-watt improvement over Intel’s Xeon Platinum 8180
