Brodie, please stop violating Tux in the thumbnail. We talked about this. It is not appropriate or nice to do that to Tux. Just because he does not verbally object to it doesn't make it okay.

Props to that one guy out there mainlining KDE Plasma on their 1.2GHz single-core intel printer CPU.

Support for Carillo Ranch should be continued in case of sidewinding time travelers. If a time traveler from a timeline that diverged from ours just before the successful launch of carillo ranch in his timeline sidewinds into our timeline while carrying a Carillo Ranch Linux machine, he should be able to downgrade his kernel to the latest common ancestor of his kernel and our kernel and then upgrade his kernel to the latest version of our kernel to get the security patches that are relevant to the malware biosphere of our internet, without losing support for his own processor and stranding himself here because he can't contact his guild leader anymore. Even if you hate time travelers, you have to be concerned that his body might flash-rot a few years after his divorce from the voice of Miandir. That could take out a city, especially if he doesn't self-isolate because he doesn't _know_ he's divorced from the voice of Miandir, because without a computer to receive such a rare warning, why would a time traveler ever guess that they are the only time traveler on earth? Sean, are you out there in this comments section, researching Linux support for Carillo Ranch? It's me, David. GET OUT OF THE CITY! You are divorced! I have done almost all I can to prevent catastrophe. The Linux foundation, it seems, has not, although I never knew them to be anarchists. Is it possible that they don't know about sidewinder resource fuzzing at all? Usagi's second pillar of universal hospitality? They absolutely must have an ambassador singleton, nobody achieves this level of coherency without one. So who is in charge of hospitality?

Tech people have such a warped view of hardware specs now. I remember a time when all of the world ran on lesser hardware. What's now discarded as a useless 1,2 ghz once ran the international banking system and the leading armies of the world.

I've found exactly two references to Carillo Ranch that isn't about the driver support being dropped. One from 2008 and one from 2013. One is an error log on the Gentoo forums that mentions a Carillo Ranch MCH Device not being found. The other is the same but on the Lenovo forums.

this will probly clear things up a bit; vermillion range is the codename for the cpu, carillo ranch is the codename for the motherboard that implements the vermillion range chipset so... EP80579 goes into the LE80578

Why install the printer in Linux, when you can install Linux right into the Printer? XD

2:39 A lot of things can get done with a 0.048 GHz ARM SoC that has less non-volatile storage than this thing has cache. 1.2 GHz is _plenty._

intel generations 1-3, when the mobile cpus were marked with "M". instead of being soldered to the board, they were actually removable.

It was a driver for audio devices handling audio on weddings on Leo Carrillo Ranch. No more weddings in linux world. I suppose it wasn't really used that often anyway.

That's Intel's First SoC since 80386SX. Also that's Pentium M, so basically Pentium 3 with PCIe 1.0 root, embedded DDR2 memory controller and MCH glued UNDERNEATH the CPU. It had astonishingly high failure rate. I knew of this platform from marine gas cargo control systems but never thought it was in laptops.

Thank you for bringing this to my attention, Brodie. I will immediately get on to the Kernel team to let them know I need to this to remain as I often use my printer as my primary computer and as you may imagine, operating at 1 frame every 4 seconds (once the drum's warmed up) means I'm prone to clicking on the wrong button and with ads so often being malware and the CPU being too weak to run an ad-block, it's important I have the latest security patches.

Movidius is still a bit of a sore point. A project I was involved with at the time got scuppered partly because Intel bought Movidius and refused to sell or license their chips. (That wasn’t the only reason the project died, but it was one of the nails in the coffin)

What about if we have Ram Ranch hardware. Do we need to send pics of that?

Seen this a few times now. Intel is so good at upstreaming that they put in work on in-development products. Sometimes these never make it to market, and Intel then removes the drivers for them. I recall this happening with some AI driver or another a while back. Of course, usually they don't look at it like "What the hell is this?"

And here I thought this video would be about Linux dropping support for System/380, the imaginary CPU that MVS/380 runs on (it's a trick to allow a slightly modified version of MVS 3.8 to run MVS/XA software).

Laser printers can last a while, and may need at least a new LTS kernel for security updates to prevent various buffer overflow BadUSB and network exploits (there was a buffer overflow on the Linux driver for Intel Gigabit NIC just several weeks ago). Maybe that printer is old enough not to do USB Host or Ethernet. But nowadays, we need to perpetually update any hardware with new software, or replace it, or put it behind an FPGA stateless firewall between a USB to USB data transfer cable (hint: that third option isn't really much available to the public yet).

Intel Movidius does exist. It is a Vision Processing Unit that is added into select CPUs

Wow! That HP printer. No good memories from that one. A blast from the past form one the most expensive and problematic (not counting some deskjet) printers I had to work with and with an awful support in warranty, from HP.

Its still a big achievement to realize a working driver, even if product management of the chip maker company finally decides that it wont see sufficient business cases to start production.

maybe somewhere in a parallel universe, this cpu was actually used, and some random kernel pr got merged to the wrong universe, ours

Looked up support page for one of those printers, most recent firmware is July, and those printers are big photocopier type ones. HP might still need support, then again, they might not.

Never would have guessed HP would have an x86 SBC instead of Arm.

all this talk about Carrilo Ranch makes me imagine someone preparing food on computer hardware thats openly laying on a table somwhere.

Wasn't the whole FOSS movement started by Stallman not being able to upgrade his printer or something? So, careful with removing FOSS support for printers... :)

From Tomshardware _As far as we can tell, Carillo Ranch was supposed to be a platform/motherboard for EP80579 embedded CPUs, which combined a Pentium M core known as Tolapai with the Vermillion Range chipset and a memory controller._ Intel Carrillo Ranch Pentium M compatible Vermillion Range.

One question, u do realize literally all 'combo' printers and office printers use linux under the hood? Even 4 thousand dollar massive office devices like the Xerox ones use linux combined with some slow stable cpu like a pentium 3. Yes there are brand new office printers with pentium 3 era chips inside of them running linux because they are performant enough, and nowadays incredibly cheap. using platforms so old kindergarden childred draw schematics for as a leisure activity. Removing linux support for embeded chips means making the life of device manufacturers much harder.

The beauty of open source: even if it's been abandoned publicly, if it's being used somewhere it's theoretically possible for someone to make changes and continue maintaining their software. There's also a large number of communities and businesses watching. This way, abandoned software can be removed without massive risks

the Portwell CATO-3000 is some networking equipment that uses this processor too!

Brb, building a desktop around that printer motherboard.

Favourite Intel CPU generation? 486. First PC we owned was a 486DX/33 with 8MB of RAM, so I've got lots of good memories of it. Also the point where x86 was first delivered in a "complete" form, without the need for an external FPU. Only other ones I've had were a second-hand Pentium MMX, a Pentium III 500MHz, and a Core i7 3930k. Everything else I've bought has been from AMD, due to being better value for money.

Looks like the Intel EP80579 processor is used in some NAS and network devices. Axiomtek's NA-200A, and Netgear's ReadyNAS NVX both seem to use it.

When I clicked and when you said Intel, I thought this was going to be about Pathfinder, Intel's RISC-V project that only ever existed inside their "Simics" simulator (is that somehow distinct from an emulator?)

The funny thing is that we'll find that one guy right after it's removed

2014 Lenovo Thinkcentre Edge 73, a secure mini tower may have also been connected to the Carillo Ranch mainboard

Interesting! Maybe my HP monster, the lovelily named MFP521dn, has the same Intel insideⓇ, as they mention a "800 MHz processor, 256 MB RAM" in the specs. I'm not planning to upgrade the kernel anytime soon, but I did the recommended software update a while ago, it was to fix a bug in the webserver iirc. :)

these had tolapai SOCs. it's mainly in printers as you've found, routers, etc

Man, I guess we won't be upgrading the kernel on the old printer...

Favorite intel cpu generation... Yorkfield Those things just didn't stop working like at all (yes I'm talking about core 2 quad, specifically a q8200)

*BSD is well known for having a branch that will compile on any platform except a Analog systems. Linux is not quite the same. The split between Kernel 2 and 3 dropped a lot of legacy drivers (ESDI, Token ring, etc).

New Linux ARG dropped?? Is this some kind of SCP type nonsense???

Remember hearing that a CPU support was removed from the linux kernel, the CPU that was removed never got released. So I would think Intel added support for this CPU(either so it worked out of box when it got released or so they could test it in house) So it made sense for support for a never released CPU to be removed from the kerenel. Heck I am sure the linux kerenel can be heavily stream lined if more ancient hardware support was removed.

Please bring this back. I use the eepy ceepyu (emulated on qemu of course) and this update breaks my flow. Now I can’t update 😿

Are they going to end support for my teapot with a 418 processor?

There are so many obscure CPUs and platforms out there - many of which you will not find any public information on. We had tested some 10nm Intel CPUs in 2017 (when intel still said they would give us the products in Q4 that year), we have some Epyc CPUs with different memory support and some that you can only find some obscure references from IBM, Oracle and Amazon. 0.9-1.2GHz singlecore low-power CPU in 2008? there might be many millions that were actually sold and are still running. For printers the kernel is likely no concern, but would not be surprising to see the code being revived in 1-2 years when a manufacturer notices he still needs those systems. People tend to forget that private Desktop-Systems mostly used for gaming are just a very small section of the CPU market. In early 2020 Intel already had about half their production-capacity in 10nm but only in late 2021 did they release desktop-CPUs on that node. Those facilities were up and running producing things like 20core CPUs for communication-infrastructure.

if there are products that use it and it was launched then it exists? I don't see the issue?

hey, at least we got 64 bits in emdeded devices out of the ep80579

I bet, if anything, said chipset never left the lab. There are always a good number of such chipsets, but typically the patches don't get merged to support them, and are only kept in house, or at most on the company public github. Also, if it did leave the lab and found it's way into embedded devices, most embedded devices ship custom kernels. So, any manufacturer still supporting this hardware can revert the patch on their kernel.

it seems that the systems that would be using this driver are older systems that would not be running modern software to begin with, it also seems like if for whatever reason these systems would need to be updated it they will have a headache on their hand. from what some of the comments have said, it seems that it was used in a lot of critical operations equipment and other business applications. things that might not be updated or upgraded for a variety of reasons. someone also said that they have a high failure rate so it might also be a non issue over time because eventually all these chips will be gone. but it's not quite an "imaginary" chip, it's quite like some of those other extremely obscure electronics hardware that if you know what it is, you needed it. rather then, you could just happen across the chip or device randomly.

I thought that this is going to be about Itanium-64 (IA64)

May favourite Intel CPU Generation is the original Pentium (P95). It was really ahead of it's time.

Where will I farm my carillos now???

I know that is probably very apchour protect But it's the reason to get the length to stop support i driver ?

the ram ranch written on the whiteboard caught me off guard x)

Hmmm... seems youtube doesn't like the product name string. You want to look for the EP Eighty Five Seventy Eight, not Nine. It seems from looking at a product page and a recast page intel released, that perhaps it was canned for the new version with no lead in it. Perhaps.

2:14 I used a machine that ran at 0.9GHz well into the midst of the pandemic. 1.20 GHz _should_ be enough for many people.

"Nobody is going to run mainline Linux on a 32bit 1.2GHz CPU". Well, I do not have that specific CPU, but I like to use hardware that is not too much overkill for the task I want to use it for. For example, I use Debian 8 (later ones do not boot, it's either not enough RAM or because the CPU does not have some feature) on a 233Mz Cyrix MediaGX CPU with 128MB of RAM. I use one such PC to configure switches (it's small and has a serial port), run VPN (it manages a few mbps, but that is enough for me in that case) and use it as a router for testing/configuring some systems. It works great for all of that. I plan to use another one of these to get the data from various devices (power meter, solar inverter, generator) over modbus. I think 233MHz and 128MB would be enough for that too. I'll run Debian 8 on it, but I considered DOS and Windows NT - but I'll try Linux first because I can boot it over network. DOS would be good because I could use a small DiskOnChip2000 SSD, but I would need to do more stuff to program the interface compared to Linux and libmodbus.

The datasheet is 100MHz off from a Back to the Future reference. Dammit!

I was watching the video and wanted to say that you missed it, but you sped right by the part that said that "Carillo Ranch" was a motherboard not a chip. So that is what got you confused about that chip number.

you are being a bit dramatic saying its unreleased hardware, alot of hardware still use that chip, you should know that many devices uses linux, i was looking at an ATM seval years ago and it had that chip, i have even seen some that are still in use with Pentium 3. It man not be a consumer product, that dont mean it dont exist, it mean its a niche product

Favorite Intel ISA CPU... hmm... I'd say 2nd gen Opteron for its amd64 extensions and amd-v tech... best dual core CPU I've had

It's not imaginary, it's real. Real shit.

My favourite Intel CPU generation? Bloomfield. Had an i7 920 long ago in the first pc I build myself.

my guess: soon there will be an outcry from the NSA, because they want to keep their linux support for their hardware platform ;-)

I wonder if it's some military contract thing that was never a commercial product?

But what about 400 years from now when the Enterprise stumbles across one and needs to pull data off it to save an ancient astronaut stuck in a pod and we removed the driver they need from the kernel in 2024 so someone ends up dead because of us. Assuming that the Enterprise runs on Linux cause of course it does.

The Intel EP80579 Integrated Processor and associated chipset was known as the ill-fated Carillo Ranch chipset. It was one of Intel's biggest flops since their foray into 32-bit a long time ago with the 80i432 CPU, the i432 is not compatible with x86_32 or x86_64 designs.

i didn't see what you wrote on the board until you addressed it. i've won, but at what cost?

A 1.2 GHz 90 nm single core Intel CPU from 2008 makes me think it's some kind of Pentium M offshoot. Good old 686 IA-32

It's too bad the high dollar installed base you found carries the HP brand. Owners have already learned to shut off updates, regardless of the bugs and attack vectors they may fix, to remain opted out of the supplies source locks recently added.

Favorite Intel generation? Well, the only Intel CPU I ever owned was a Skylake, so I guess that wins by default.

just to add, since intel is on topic, i notice that linux based on OLDER devices relying HEAVILY on intel drivers. which known to be UNIVERSAL. which many old AMD devices are USING in LINUX. if i never use linux, i will never know that. it kind of makes me respect the company more. despite many of their bad business decisions. and that practice apparently have been long before AMD make their "universal stuff like the FSR feature. inf act my 12 year old AMD device running on linux right now uses some of those INTEL drivers. and it runs great.

Any code removed from the kernel can be maintained as a patch. I maintained two kernel patches for many years. No big deal. If it needs to go back in, it can be done.

Oh hey! You could probably play Wing Commander: Prophecy on that thing.

It is hard to prove a thing doesn't exist.

Could it be that Carillo Ranch was deleted from the archives?

Most linux distributions already dropped x86 support (while windows 10 still gives support) so i wonder how that survived so long :D

You had me LOL. I thought they dropped RiscV hehe

I love digging deep into old drivers, old software, and the deep web by following weird outdated website links 😀

Sounds like a dressing at subway lol

90nm wasn't that shabby in 2008. That's like Pentium 4 era node size, somewhat dated by then but plenty fine for embedded applications.

If you want some fun, try playing the driver lottery with old but once fairly common Bay Trail hardware. So far I've got a Linx 1010b running Mint fine/good enough ootb (after getting grub 32bit efi on it) but my Archos wont boot Mint (black screen) and Debian 32bit and Fedora lack touch screen support among other things.

LMFAO I JUST FOUND OUT ABOUT THAT SONG BECAUSE OF THIS VIDEO, wouldn't have even bothered looking it up if you didn't point it out

There was me hoping there would be a MIX implementation.

skylake 14nm was such a chad soc it lasted 7 years +++

If Linux dropped something it is REALLY small pickings. I used to use QIC-02 in the 90s. This sounds like a simple vga device or maybe video output modulator.

Driver cleanup, i like it 👍

Boy I hope my nvidia drivers would magically pop into existence

Dammit I miss it already.

"Linux is generally known to have an incredible range of hardware support" (queue laughtrack)

perhaps it has something to do with space, or printers ;)

and what if this was actually never released and this was an hidden backdoor driver?

Bruh, reppin Ram Ranch 🤣

18 naked circuits in the showers...

noooo my imaginary computer!

NSA backdoor?

Twice the speed of the processor of the raspberry pi 1, more or less the same process node.

Great, now my dream computer has stopped working...

Now that this has finally dropped I can use my imaginary CPU platform at last!
