Slackware64 and Kaby Lake.


I have been looking at new motherboards and processors, of
course, and was wondering how well the new Intel Kaby Lake CPUs are supported by Slackware Linux?
Originally, I was thinking of the Devil's Canyon series, but the prices have shot up as the supply dwindles (they are no longer in production).
OTOH, the new AMD Ryzen processors look very promising with 8 cores and 16 threads. Perhaps, I should wait and see how well they perform "in the real world."

So I got my cabbage pickers on one of these: from System 76
the lemur is the one I grabbed
https://system76.com/cart/configure/lemu7

--I loaded my distro of choice Slackware of course. (I chose -current)

I would say I absolutely needed to roll my own kernel or I could not use X.
I believe that was the only issue I had. Note support was included in kernel version 4.9 (for graphics driver, attached to Kaby Lake)





Code:
uname -a
Linux lemur 4.9.10-rh #1 SMP Thu Feb 16 20:52:15 EST 2017 x86_64 Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz GenuineIntel GNU/Linux

(I also had to use elilo, since the "bios" is now likely to be UEFI) No issue with Slackware install

--Performance wise it is a huge step up from what I had been using...

Ryzen is fairly new so don't expect out of the box support just yet. AMD will probably release the firmware after it starts getting development in the kernel code, but probably not beforehand.

As a good rule, wait at least 6 months on new hardware to get decent support in the kernel.

It appears the 4.9.10+ kernel is needed for AMD Ryzen support.

Based on that article, it looks like you might need 4.11 for motherboards using the ALC1220 audio codec...

Quote:
Some Ryzen launch motherboards are using the Realtek ALC1220 audio codec, for example, and that is support is only coming to Linux 4.11. Among the AMD motherboards using the ALC1220 codec are the Biostar X370GT7, Gigabyte GA-AX370-Gaming 5, Gigabyte GA-AB350-Gaming 3, and others.
I'm eagerly awaiting this and looking forward to benchmarks once the NDAs have expired. I've been wanting to upgrade my computer for quite some time, and if the results are close to what AMD shows, Ryzen will likely be my next CPU. I already have 2x16GB DDR4 RAM and a nice 1000W Corsair HXi PSU just waiting for a processor to properly utilize them

"Kaby Lake is unleashed with Linux kernel 4.10"

http://www.pcworld.com/article/31736...ernel-410.html

The article is dated 1 March 2017, but it would appear it was actually written approximately two week ago.

This is the Slackware forum. We aren't all familiar with Ubuntu and can't make easy comparisons since they don't use vanilla kernels (they are modified from the originals you can get from kernel.org, which is what Slackware uses). It is possible they've added support to that version, but you'd need to check in the Ubuntu forum.

For Slackware, you'd likely need at least the 4.10 for proper CPU support and 4.11 for any motherboards using the ALC1220 audio codec. Whether Ubuntu has pulled the code for those into their 4.4 kernel for 16.04.2 is something you'll need to find out from them.

My guess though... I doubt it has support. However, Phoronix did some testing of the Ryzen CPUs and used Ubuntu 17.04 with a 4.10 kernel. So, you should at least see support there.

Quote:
Ubuntu 17.04:

After assembling the system and powering it up, the Ubuntu 17.04 USB-based installer proceeded to start without any problems! No having to pass any special kernel command-line arguments, no hitting kernel panics or other issues like with some past CPU launches, and this Ubuntu 17.04 installer proceeded to run, detecting the NVMe SSD storage and everything else just fine.
After a reboot, the Ubuntu 17.04 installation with the Linux 4.10 kernel booted up just fine. It was a very pleasant experience. But keep in mind that Ubuntu 17.04 is still in development and will not be officially released until next month. I was using Ubuntu 17.04 since it should be the sweet spot for Ryzen with using the Linux 4.10 kernel. On distributions using older kernels, you may run into problems. For today's testing, all of the benchmarks were done from an Ubuntu 17.04 snapshot as of this week with its stock Linux 4.10 kernel image.

Well, i just got a new laptop with Kaby Lake processors with Hybrid GPU and X will not work until i compiled Linux Kernel 4.10.3 for new firmware required by i915. Things works out completely otherwise using Slackware current (audio, wireless).

Willysr,
Thanks for the information.
I am leaning forward Intel. The new processors from AMD sound exciting, but I'm thinking that, perhaps, it might be better to wait for the second generation of "Zen" CPUs. What is that old saying about buying version 1.0, of anything?

I just ran into the same problem as described here.
I bought a Kaby Laky i3-7100 on a Asrock H170M-Pro4 motherboard. But can't get X to work with anything other then standard vesa mode.

I am running Slackware 14.2 with 4.4.38 kernel updated using slackpkg+

I read somewhere that giving a kernel option to lilo like this would help:
append=" i915.preliminary_hw_support=1"
But still no success. Maybe this only holds up for Sky Lake.
http://www.phoronix.com/scan.php?pag...prelim-support

So now I understand I would need kernel 4.10.3.
Or I could downgrade the cpu to an i3-6100 Sky Lake.
For now I have inserted an old Nvidia gt210 card, that works ok with nouveau drivers.

I will need to look into a good procedure to get 4.10.3 kernel source and install that. But I am afraid that would be more trouble, as I am already scared to install a kernel upgrade as delivered via slackpkg+

Read the README provided by Patrick and you should be fine :-)

Can I combine 4.10.3 (or 4.10.8 which is the latest) with Slackware 14.2? Or do I need to go with -current?

I found the kernel update thread with Bass madrigal's procedure :
http://www.linuxquestions.org/questi...ml#post5659160

I need to choose a good .config baseline (from 55020) : https://dusk.idlemoor.tk/config/

I use also ZFS on Linux ; I see they are already supporting 4.10 kernels.
And I have UUID in my lilo and fstab, so I need initrd + generic kernel I think.

Which README are you referring to? I have searched the slackware 14.2 DVD and did not really find info about installing kernels straight from kernel.org

Thanks
