You could try the other Linux thread stickied in this forum: viewtopic.php?f=21&t=56878

It’s title may say Linux Install Issues but 20 pages in it’s already way more than that, so it seems like a fitting place. Or you could make another thread :) There’s plenty of places on these forums (even in the Off-Topic ones: viewforum.php?f=14). I’d be more than down to have a Linux back and forth debate, I find them fun. But without congesting actual support threads (this one is stickied for a reason).

Cheers,
Mike

Hey guys!

is there a new official Blackmagic ISO based on CentOS with Resolve 15 now that's out of beta?

Do some of you have the link to it?

Thanks!!!!!!!!

A new ISO? I don’t believe so. But you can just download Resolve 15 and install it normally. Just make sure you install at least the minimum required driver version (or CUDA) version and you’ll be fine.

As always, the link to the current build image ISO is in the Linux Installation Instructions PDF file that is part of the Linux Resolve software download from the BMD site.

There is a new ISO for 15, but it's basically the same as the last 14.3 ISO with the exception of the install files in /opt/resolve/Releases being replaced with the Resolve 15 Studio installer, and the inclusion of the 390.42 NVIDIA driver required for Resolve 15.

Greetings, Dwaine.
For Linux newbies, has anything been added to the LINUX ISO that improves ease of quickly launching Resolve 15 -- without the enduser having to scrape up ftom the Internet, installer packages for other drivers such as some required to get Fairlight page to fully work?

Or is everything already there (barring some Linux drivers needed for connected peripherals)?

If you build a system drive with our ISO build image, Resolve should just work, assuming you have proper hardware. The build image is NVIDIA centric. It won't work with AMD GPUs.

After building the drive, you still have to install the Resolve app itself, which is in the /opt/resolve/Releases folder. As per the Linux Install Instructions PDF, also in that folder.

Also, the current build image has Desktop Video 10.9.7. If you have a DeckLink 8K card, you'd need to install Desktop Video 10.11.2. Details for doing that are also in the PDF.

Oh, OK Thanks for that.
Do know, Dwaine, that every additional effort you and your cohorts will yet put into enhancing the ease of installation, setup and smooth, comprehensive functionality of Resolve for Linux is hugely appreciated.

A growing number of us creatives are ever more fed up with the bloated complexities and drivers-breaking shenanigans of later Windows and OSX iterations from Microsoft and Apple, respectively.

totally agree with Pete!

so much that I think you could plan a very nice thing for the future:

a sort of BMD distro, based on something but with your repos and with easy installation and update of the system.

Tommaso is really onto something -- and I believe Blackmagic Design would do well to protect their own interests by ensuring that their software development efforts on the Linux platform also moves in the direction of developing a Resolve for Linux variant that leverages new technologies while also maximizing stability and security.

Sadly, it appears to this newbie at least-- that the Resolve for Linux tradition does little to secure new technologies for the Linux base of BMD endusers.

Of particular interest to me at least, is that
Linux [Debian flavors] would lend to more simplified OS upgrades and system tweaks without packages' dependencies getting in the way of clean, speedy setup and maintenance for users.

If I'm arguing for a solid Debian based Resolve for Linux distribution to be run alongside the RHEL/CentOS variant, so be it. Then let the Resolve endusers "vote" to give BMD the impetus to move forward with whichever flavor we decide.

I beg Blackmagic Design to hire additional, bright, efficient, experienced software coders [expert in Fedora maybe?] to get this proposed, new approach to meeting customer needs, addressed with enthusiastic intentionally.

• Generally more speedy OS performance, likely, depending of course, on Linux variant, system optimizations and installation scheme.

Ok some quick comments - although there seem to be "another" thread for this ;)
CentOS comes with an ancient Kernel. Depending on your hardware, thats a dealbreaker. The newest chipsets and components will never be supported by an kernel as old as the default Centos 7 afaik they are still on 3.10 - its a good distro, i have it on my Webserver, but i would never use it for an AV system.

So for people with half recent hardware: check out distrowatch.com and check what kernel the distros are on per default.

Some examples:
Arch Linux 4.19.4
Ubuntu Cosmic 4.18
Fedora 4.18.16
Debian Stretch 4.9.30

BUT,
RHEL and Centos 3.10

The RHEL kernel lagging behind and being severely limited is a common misconception to most people who don't understand RHEL development. Yes, the kernel version is 3.10.0. All that means is that the kernel RHEL 7 was initially built with (back in 2013 when the package freeze occurred for the 2014 release) was 3.10.0. The latest RHEL kernel is 3.10.0-957.1.3. This includes functionality from the kernel 4.x series.

The version number for RHEL holds little value. Red Hat does use the old original number, but then adds patches from both in house fixes and upstream kernels into their own. During Phase 1 development (which will end in Q4 of 2019 for RHEL 7) Red Hat backports features, bug fixes, and security patches into their kernel. As well as add new ones on customer or industry request. Phase 2 and 3 typically remove feature updates and bug fixes respectively. The kernel version itself doesn't change in order to prevent introducing ABI breakage for packages.

My universities HPC center where I work runs RHEL 6.x, based off of the last 2.6.32 kernel. Our newest nodes are Xeon Skylake systems with Tesla V100's in them. My home workstation running CentOS 7 has three 1070's and an i7-6850K Broadwell chip. They have no issues on this platform. You can't judge an enterprise distro off of version numbers, they don't apply.

If it makes you feel any more at ease, RHEL 8 which is coming out next year (and is in public beta) is built from Fedora 28/29 and utilizes kernel 4.18.0-X as its base.

Cheers,
Mike

As a person who does use the platform daily for personal and work use, have a little trust in what I'm telling you. And EPYC (Naples) is supported on RHEL 7 as of 7.4.

AMD server chip support: https://access.redhat.com/articles/65431
Intel server chip support: https://access.redhat.com/support/policy/intel

Desktop Skylake was introduced in 2015, the new SP chips are from 2017. By your logic Skylake shouldn't even be supported as RHEL came out in 2014 and was package frozen in 2013, but it is.

RHEL is not the same as Debian. Please read through the development cycle of RHEL: https://access.redhat.com/support/polic ... es/errata/

If you are having bad hardware crashes or lack of certain hardware support, you can always try your luck using the CentOS Plus kernel, or the Mainline/LTS kernels available from ElRepo.

Cheers,
Mike

Edit: Kaby Lake support was introduced in RHEL 7.4 (CentOS 7.4.1708). Just saw your post.

Did you skip what i was saying, Kaby Lake - which was introduced in 2016, is supported by Kernel 4.10, which was released in 2017. Also i dont see Kaby Lake on the list of supported Chipsets in the Link you posted. I think we have a different opinion about what is "recent" hardware, my suggestion was for people that use recent hardware, i.e. my PC has a Kaby Lake Chipset - so i wouldnt be happy running CentOs 7, i dont know why you argue against that. I was just pointing this out for potential Linux users that MIGHT have newer hardware than you.

Take a deep breath and relax Evgeny. I was writing my response while you posted that. Take a look at my post edit above.

What I'm recommending you do is to spend time researching the distribution and verifying the hardware you intend to use works. My original argument was about not using the kernel version as the end all factor in determining RH support, as it doesn't apply the same way as it does to other distros.

Even if the backported Gen7 CPU support: Just Google it, CentOs is NOT a recommended distro for very recent Hardware Architectures. I have no idea why you try to make people believe otherwise. It is a great distribution - and like i said, i run it myself, on my server, which is running VM's, Webservers. SAMBA etc.

But not Resolve.

EDIT: What i ALSO dont understand, if you like yum/rpm etc. even then you can just use Fedora or Suse. almost everything will work like you are used to from CentOS but you have a much more modern distro.

I'm not trying to make people believe anything. I'm trying to inform you to the development practices of Red Hat, and by derivation CentOS, as well as provide fact responses to your claims. I'm not sure what you deem "recent". If you want bleeding edge day zero support, use Arch. I'm not saying there aren't certain hardware architectures that are unsupported, but you're making it seem like everything 'new' isn't. Outside of Zen 2 and EPYC Rome, there really hasn't been any 'new' hardware recently. Particularly anything that requires a substantial patch to the kernel.

evgenymagata wrote:But not Resolve.


Resolve works perfectly fine on CentOS. Ask anyone here using it, and ask Blackmagic Design who develops on it.

They have different use cases. Both in terms of support, practice, and releases. With a distribution like RHEL you are guaranteed a system that is rock solid (usually after the X.2 release) and will not fail (usually). You get a long lifetime out of the product that means a lot for users. it provides a stable development platform that won't break in the next year with the next release. For people that prefer long term stability, predictability, for both production and development purposes, it's a great platform. Fedora is the upstream of RHEL, so if you use that you'll know what will be in the next version. But it can be iffy at times and the development tools move/change too rapidly for the M&E industry. Some environments will actually mix the two together, and use Fedora client side with RHEL server side.

At the end of the day it's really up to the user. But it's better to be well informed when making these decisions.

Mike

Exactly that we agree on: before choosing a distro make sure it supports your hardware. If it is very new, chances are that CentOs will not support it.

This is true. What I am trying to say is give it time and it likely will be supported if the distro is in Phase 1 development. That's really about it. If you don't have the time, and the hardware is unsupported, then the decision is really already made for you (if the kernel isn't involved). Otherwise you can use the kernels from ElRepo which build both the latest mainline and LTS kernels for use on RHEL and CentOS. Just sharing the options available to you.

I can't get Resolve to run on my CentOS 7 Build.. 'Segmentation fault (core dumped)' Is what the terminal reads.
everything updated with yum, tried all sorts of things dotted around the web but nothing is working.
By far the most difficult piece of software I've ever had to try and install, Nuke, Houdini, Maya all install and play fine.

I don't have a decklink card? Is it mandatory to even get Resolve to run?
Would a Nvidia GPU be Better?

Im on a very basic i7 build 16gbram, firepro v7900 gpu, ssd, not a fast machine at all but all pretty mature so should work fine i'd imagine. Obviously not the fastest machine, but its just for home so not worried about speed just testing and learning.

Any ideas?

Also i dont see Kaby Lake on the list of supported Chipsets in the Link you posted. I think we have a different opinion about what is "recent" hardware, my suggestion was for people that use recent hardware, i.e. my PC has a Kaby Lake Chipset - so i wouldnt be happy running CentOs 7, i dont know why you argue against that. I was just pointing this out for potential Linux users that MIGHT have newer hardware than you.


Kaby Lake works just fine on RHEL7.5. Even a recent mobile CPU like E-2186M (used by HP/Dell in their enterprise laptops, released Q2 2018) works fine. Built-in graphics and all. That supported cpus link by redhat is outdated (Updated October 25 2017). Here is a KB article by them where they clearly list the 3.10 kernel that supports both the CPU and the iGPU on it:
https://access.redhat.com/solutions/3465951

Regardless, use whatever distro works for you. I can tell you that in my industry (Animation studio) RHEL/CentOS is practically that only distro that matters. Big hardware vendors only certify for it and big software vendors - like Autodesk - only supports RHEL/CentOS.

BMD is correct in focusing on that distro. Big thanks for even doing Linux.

@Ali:

You need to install CUDA. Unfortunately, BMD did not make it an either/or system for detecting
whether CUDA or OpenCL exists on your system. Both libraries need to be present, even if you have an AMD card. All you should need is the libcuda library which you can get from running the NVIDIA driver with the --extract option. I’m not 100% on this as I don’t have an AMD card, but from CUDA experience that’s the only user land library that really matters.

Mike

Thanks Mike,
I'll try this and report back. Should I install cuda then reinstall resolve?
Resolve doesn't seem to have an uninstall, whats the best way to trash everything resolve related if I want to start from scratch on the install,

Best

Not sure if you’ve attempted it already, but there should be no need for a reinstall. The library is dynamically linked at runtime so as long as it’s in the proper location, you’re good.
