Yep, completely agree that its an Intel limitation.

I didn’t see that about USB3 (my Intel system provides USB 3, and still has the 50 endpoint/25 device limit), I’ll take a look, however it sounds like AMD is just generally better.

It’ll be a shame to lose Quick Sync, but it’ll probably be worth it.

However this reiterates my thoughts about USB4, since it is a Thunderbolt derivative, and as mentioned in your link Thunderbolt doesn’t have these same limitations.

These things can be confusing to understand and seems like a reasonable question, I don’t pretend to fully understand everyone’s complaints.

Doing basic research shows it as “a British news website”, founded by a British journalist (who Murdoch didn’t like so already sounds like a nice guy) and former head of the BBC, and an American who spent 4 years here as Ambassador under Obama.

Not exactly sounding like Bezos or Murdoch levels of evil here.

The main issue is that its all been dealt with in secret, consultations with Observer employees such as the editor haven’t taken place so its just leaving a sour taste, along with a lot of questions as to how they reached contradictory positions on why they should sell the paper.

👍

That sounds absolutely gross.

I’ve tried to respond to everyone who have given their opinion of my set up in a top level comment to try and keep it on topic. You can respond there if you feel like you have anything to add.

Citation please? The spec is fine with it, its just Intel that put in artificial limitations.

It’s unfortunate that the conversation has been derailed by people advising me on “better” implementations, so should probably summerise my journey that has got me to this point.

I started home labbing and self-hosting over 25+ years ago, with a large HDD connected to my home PC, HDMI to the TV and ripping DVDs. The disk was probably PATA back then. Yeah, single disk and it probably died at some point making me realise I needed backups in future. I replaced it with a dedicated server I build in an ITX case. A four disk CHENBRO ES34069, back in the good old Athlon days. Each one of those disks was SATA directly connected to the motherboard. And it did the job, except for getting extremely hot and I had a number of disk failures over the years.

Looking back, I can’t guarentee that it was the heat from the system that caused premature failures rather than 2008 era disks just not being as reliable as they are now. But it was hot, and that could not have helped and I had a number of disks over the years that failed in various ways.

I learnt about RAID, and ADM on Linux making arrays and generally not losing any data any more.

My upgrade on that was required as I find that storage requirements outpace what I have, so it ultimately was replaced with a full tower system. A Zalman MS800. At this point I tried to go the whole way. SAS controller cards! Silverstone SAS/SATA hot swap drive bays! RAID disks!

This is when I learnt that I don’t like large RAID arrays, when scrubs took several days and either extending/upgrading/replacing a disk took forever and started using 4 disk arrays in parallel with mergerFS overlaid. Honestly that was the best discovery and its not lost me anything in over a decade.

But SAS became a hassle. I had a controller card fail at one point, so I picked up a replacement which turned out to be a fake, and I’ve had to replace an 8087 cable a couple of times. Its hot, I’ve gone through a few replacement drive bays and they’ve all had small cheap fans on the back of them that over heat, make noise, and don’t do a great job of shifting heat when its part of the same case as the rest of the computer. So I’ve investigated alternatives.

The current solution has evolved to now have 4 “TERRAMASTER D4-300” external storage devices. These are probably the best I’ve come across, they fully expose the disks to the hosts including SMART and even the full correct serial numbers. The speed is absolutely not an issue and I find the benefits of SAS have been completely overstated when dealing with 5/10GB USB connections. I can do a full scrub of a 4 disk RAIDZ over night. These have large fans on the back, and I’ve never had disks this cool when dealing with internal storage, SMART is much happier. You are allowed to have your own opinions, but honestly I’ve been using this setup for a long time and I have no regrets. It is much simpler, and the limitation is very much on the speed of the storage device rather than the type of cable.

The only issue is older Intel gimping the USB enumerator to only allow 50 endpoints, which is 25 devices (less if you have hubs), and even on newer systems they only doubled it.

Let me know why you think my set up is wrong, and I’ll explain how I’ve probably tried your way and I don’t care for it.

Nice!

The 127 endpoint limit isn’t even that hard, the spec is 127 endpoints per controller, however Intel appears to have done the dirty and restricted systems to 127, and even then you need two controllers to get that high. 😡

If AMD let’s us use multiple controllers to go higher then thats awesome, but its also following the spec.

[Edit] I’ll have to see if I can find the video.

I’m not. Intel does not let you get that high.

From Intel.

First Limitation

Fundamentally, the customer is correct. You will never be able to achieve 127 actual USB devices attached to a Host Controller (i.e. Intel system). As the customer pointed out, each USB device (USB key, keyboard, mouse, etc.) is typically counted as two endpoints (two logical USB units), and each USB hub, multiplier, or repeater is counted as another 4+ endpoints. So, it comes to about 50+ devices per each Host Controller.

With these systems it was only 25 devices total (unless you use hubs), so they introduced two controllers to allow 100+ endpoints.

It’s because of this reason that Intel added a second USB Host Controller in the majority of its Core platform chipsets. If you look at the Features page of the 8 Series Chipset ( when partnered with the 4th Gen Intel Core processor), page 39, http://www.intel.com/content/www/us/en/chipsets/8-series-chipset-pch-datasheet.html http://www.intel.com/content/www/us/en/chipsets/8-series-chipset-pch-datasheet.html, it states having “Two EHCI Host Controllers, supporting up to fourteen external USB 2.0 ports”. So, with two Host Controllers, each at 50+ device, you have a potential of connecting up to 100+ USB devices per 4th Gen Core platform system.

And thats not considering the internal hubs that split back and forward ports.

Its currently got 16 disks, and a ZigBee. So not a lot from my point of view.

However its also got the internal hubs to split the front and back ports, I think the Bluetooth is hooked up to USB on the board and there are a few other things that appear as codes. What it means is that trying to connect another disk to swap out on my ZFS fails to enumerate on the USB. I dont think the number of items are unreasonable but this little box wasn’t quite designed for this usecase.

[Edit] As mentioned on the other thread, these only have 50 endpoints because Intel, and each device is 2 endpoints so there are only 20 devices total that can be plugged in.

Because the IRA didn’t truly give up violence. They had Sinn Fein for that.

MLK was ignored, and the Black Panthers showed what could happen if you ignore them.

Gandhi wasn’t recognised by the British until the terrorist acts and rebellions in India.

The violence isn’t the “solution”, it is the response to the negotiations being ignored. Its the “good cop/bad cop” in all these situations. There are plently of peaceful groups who have been working towards better healthcare, but made no progress. This is the point where they can start saying

Either you work with us, or deal with them 🤷‍♀️

And it’s exactly how the IRA got the negotiations going. It may take a while but its the same pattern.

Minnesota Gov. Tim Walz called the fatal shooting “horrifying news and a terrible loss for the business and health care community” in the state that headquarters the company.

Actual quote. A terrible loss “for the healthcare community”, not a loss for his kids though interestingly enough.

Thoughts and prayers

I wrote Mesa but meant ffmpeg. Wishful thinking that they are able to make a generic ffmpeg encoder in Vulkan to allow it to be accelerated in hardware but not relying on bad video driver codecs.

Oh well, back to Intel.

If the driver is no longer using a dedicated piece of encoding hardware thats shit, but using the Vulkan logic then surely the quality would be essentially guaranteed by it being Vulkan conformant?

The hardware wouldn’t support b-frames in this scenario, and wouldn’t matter because your just using the standard matrixes to encode the stream and if it didn’t work then surely games would also be broken.

Or am I incorrect. Is this just standardising the API in Vulkan and it gets forwarded to the same video encoding driver? Could we not have Mesa doing a better job? 😒

The video quality for encoding has always been bad with AMD.

I’m hoping that by using Vulkan we can bypass poor quality encoders in drivers and get standardised accelerated encoders.

Why would you want to prevent strangers, future humanity or governments from using open source?
