Why I Know This Will be Painful:

So, fglrx has always been both critical to performance on an AMD-heavy system and poorly supported in Fedora due to their adamant and passive-aggressive refusal to support proprietary drivers well, convenient version mismatches between fglrx’s Xorg server support and the included version, and other components that can only be explained as behaviours that should be triggering a mass exodus from the distribution in this day and age.

The parts of this that are AMD’s fault were largely rectified by ATI’s acquisition by AMD and it’s gotten much better.  The distribution maintainers have failed to adapt to the post-year-2000 situation in lieu of impressive but still poorly performing 2D Foss drivers on most proprietary chipsets and this not only hurts the distribution as a whole, but its users, and the linux reputation.  The uninformed opinion supported only by misleading benchmarks is that many aspects of the 2D drivers perform better but those of us actually working with both drivers simply know better.

Moving on, the last I recall I did not upgrade to Fedora 23 on my last installation due to Xorg on F23 being too new for fglrx to support.  That was almost two years ago, but I don’t expect children to become adults in only two years when they are so old.  If I recall correctly I upgraded all of my system packages to F23’s versions but left the system at F22 with an F22 stock X server after a few painful nights of struggling through religious software zealotry.

Couldn’t remember which card this was because I so rarely need to make changes at this level due to the cards’ reliability, so I checked using the lspci utility:
[highlighter line = 0]

[root@localhost ~]# lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP]
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP]
[root@localhost ~]# 

So it looks like I’m on a Radeon HD 7850.

Confirmed RPMFusion still doesn’t have fglrx:

[root@localhost ~]# dnf search fglrx
Last metadata expiration check performed 1:06:38 ago on Sun Feb 14 22:12:45 2016.
Error: No matches found.
[root@localhost ~]# 

So it looks like there’s another completely preventable and fedora-manufactured storm of bullshit ahead that would already be done by now if I’d have just installed Arch Linux.

Behold, A Guide:

Blue Hat Record has a great guide and I have used their how-to articles before, I think on previous fglrx installs, so I’m going to use that as my reference first and finally chronicle the journey as I go from here.

Downgrade xorg-x11-server-Xorg and xorg-x11-server-common to the F22 version:

dnf downgrade xorg-x11-server-Xorg xorg-x11-server-common –-allowerasing –-releasever=22

But first, let’s see what versions we have for reference later:

So 1.18 for both. Let’s see what’s in F22. I did not immediately see a way to check previous release versions that didn’t just report the F23 packages for these, so I literally copied /etc/yum.repos.d/fedora.repo to /etc/yum.repos.d/fedora-22.repo, and then replaced all instances of $releasever:

[root@localhost yum.repos.d]# cp fedora.repo fedora-22.repo

And then supplied the named release=22 switch to dnf info after disabling the other repos:

Incredible isn’t it? DNF was actually the replacement of yum as one of the most manageable package managers. Yet here we are specifying verbose repositories, verbose distro release versions, and still getting bullshit. I’m sure there’s an excuse, but it is ultimately bad design.

I’m so fed up with Fedora and this is why.

So I was able to find on one of the F22 mirrors the versions from the package filenames:

xorg-x11-server-Xorg-1.17.1-11.fc22.x86_64.rpm
xorg-x11-server-common-1.17.1-11.fc22.x86_64.rpm

And now you won’t have to waste an hour of your life piecing together broken software with broken tools.

Anyway, looks like we are downgrading these specific two packages to these two specific versions:

xorg-x11-server-Xorg 1.18.0 -> 1.17.11
xorg-x11-server-common 1.18.0 -> 1.17.11

Ok, next we’ll go ahead and downgrade. I’ve documented every bit of what I need to do to clone this system so far so I’m not worried about breaking anything yet.

init 3

Will kill your X11.

dnf downgrade xorg-x11-server-Xorg xorg-x11-server-common –-allowerasing –-releasever=22

Works. Perfect. Now we download the FGLRX installer.

This site should have it:
https://support.amd.com/en-us/download/desktop?os=Linux+x86_64

Check the compatibility list for a Radeon HD 7850: R7/HD 7000 and 8000 is on there. We’re good. I go to download, and it’s a zip file. Gross.

https://www2.ati.com/drivers/linux/radeon-crimson-15.12-15.302-151217a-297685e.zip

This creates a folder called fglrx-15.302/

One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver.
Optionally, run the installer with --force option to install without the tools.

Ah. Looks like my kernel headers aren’t installed. Except that they are:

More Fedora bullshit.

Ah. They’ve split the kernel headers into multiple packages. Glad they broke that convention. kernel-devel and kernel-tools-libs-* it is.

dnf install kernel-tools kernel-tools-libs kernel-devel

Drop to runlevel 3 with `init 3` and try rerunning the installer again.

And so, after swimming around in the bowels of Fedora hell for a few hours I came to understand that making the system compatible would not be enough. I would either need to patch the source so that it would compile on a modern GCC version, downgrade GCC and risk breaking a bunch of stuff, or start following success stories in the comments on that original bluehatrecord article.

I’ll try the comment’s instructions from a user named LyPo first and go from there.

Not working.

     len = seq_printf(m, "%d\n", major);

Luckily, I have a fresh license for CLion, so not quite lost. However, without looking at the source, it appears that seq_printf() had a declared return type of void, but a variable named len is being assigned its return value. So, that’s a source issue and it could be a whole can of worms about to be opened up. If return type is really declared void, best scenario I change it to:

seq_printf(m, "%d\n", major);
len = NULL;

To achieve the same effect. Got a feeling that’s not all that’ll need changed though. I’m too tired to work on this any more tonight.

20160220 Update

Round 2.  So before I got started I google the issue I was seeing and came across a somewhat informative stackoverflow entry about just this, and it seems this is some shared code that should have been fixed already.

They reference this Manjaro Linux forum post that shows a very similar patch to what I suggested at the end of my last troubleshooting session but assign len to zero and not NULL:

After trolling in #ubuntu and #debian on freenode I found a helpful patch, because I know fglrx is pretty reliable on Ubuntu. Also, the operators for Ubuntu are total jerkoffs and I ended up getting banned trying to get the info I needed for this:

What is libfglrx_ip.a and why isn’t it in the source? No one seems to know about this. You can see the full build results here. I need to pick around the source a little and find out what this .a file is.
In the meantime, I’m still searching through the source here for all mentions of libfglrx_ip.a here.

More updates.

(Add screenshot or code)

Created symlink to libfglrx_ip.a from arch subdirectory in root folder.

It now halfway compiles!

Almost there. Or maybe not.

So, next is to find out why we’re seeing this:

WARNING: "mtrr_add" [/home/phanes/Development/fglrx/fglrx-15.302/fglrx-install.c0Svx9/common/lib/modules/fglrx/build_mod/2.6.x/fglrx.ko] undefined!

Idea for the symlink obtained from here.

After looking at this it’s now clear that my fglrx kernel module did build successfully. Woot! Did it. I was ready to put together a team for this if it didn’t pull through.

Proof:

From here we’ll want to go through the actual install, then the install of all the amd crap tools that comes with it, and then I need to trim this whole article down.

20160221 Update

So, tried the make_install.sh script bundled with it and I’m still getting mtrr_add and mtrr_del unknown symbol issues.  Since we are in uncharted territory I’m going to reach out to bluehatrecord’s main author and see if he can provide some insight into the source since he’s looked at it a lot longer and may be able to save me a few days (weeks).

In the meantime, I’m downgrading to the last known working kernel version and using the 15.20 drivers and just making it work until I get this to build right in a VM.

20160222 Update

Christ.  Apparently that’s not an option either on Fedora 23.  I’m getting real sick of Fedora’s shit as they apparently pull old packages that I would need to do this.  I’ve got the FOSS radeon driver going but this is a temporary fix.
