Re: [elrepo] skylake and nvidia

[Farkas Levente]

the question of course what does the "supported" means?

for us the supported means that the xvinfo gives us at least 16 port (or
more). unfortunately even with the latest7.3 beta it gives only 1.
what does it means?
it's working! you can start an X or gnome environment etc. but can't
really use the integrated graphics which means only a little bit better
then vesa mode.

unfortunately rh did not even comment my bz:-(
https://bugzilla.redhat.com/show_bug.cgi?id=1372383

what i collect so far?
fedora 23 and 24 fully support it out of the box.

intel linux graphics latest release 2.0.2:
https://01.org/linuxgraphics/downloads/intel-graphics-update-tool-linux-os-v2.0.2
packages compared with 7.3 beta packages:

* kernel in rhel 7.3 of course only 3.10, but fedora with 4.4 kernel
working so probably 4.4 would be enough? but intel page shows 4.6.

* mesa 11.2.2 in 7.3 ok.

* xf86-video-intel 2.99.917 in 7.3 ok. but the question the build
parameters.

* libdrm-2.4.68 in 7.3: libdrm-2.4.67, but probably easy to rebuild to
the new version.

* libva-1.7.1 require new version from based on epel.

* vaapi-intel-driver 1.7.1 require new version from based on nux
* cairo-1.15.2 ? in 7.3: cairo-1.14.2 we hope it's enough. i do not
believe we can replace such a basic library.

* Xorg Xserver 1.18.3 now here the funny part:-) in 7.3 it's 1.17.2, but
in the changelog of xf86-video-intel there is rebuild just because
reenable dri, since 7.3 is based on xorg 1.18!?? so either they plan to
rebase to 1.18 or it's an 1.18 looks like an 1.17?!

* Intel-gpu-tools - 1.15 ? use inside the xorg driver package

the other problem that i's still not able to download the source of the
7.3 beta. either i try to download the source isos or individual
package's src.rpm i always got an error from rh. so i can't look into
the spec file and start to build our own versions.

Beautiful! Thanks Trevor, this works for me with the standard kernel.

bumblebee+nvidia doesn't work yet, but at least I can work with the 
regular kernel and elrepo goodies. I'll investigate bb+nvidia and may 
get back to the list if I find a solution.

Hi Nicolas,

Many thanks for the feedback.

The wireless stack in RHEL7.2 is backported from kernel-4.1. As such we 
are pretty much bound to backporting wireless drivers to match the 
wireless stack, so the current kmod-ath10k driver is backported from 
kernel-4.1.x.


If this driver doesn't support your device, we could look at backporting 
support for that device to the 4.1.x tree driver.


Firmwares can be tricky as they can be version specific, and thus 
dependant on the driver version. If we know what files are needed then 
we aim to package them.


But at this point it all may be a little academic as I note RHEL7.3 will 
contain the ath10k driver backported from kernel-4.7 so we will be 
deprecating our kmod-ath10k package in favour of the distro kernel driver:


[phil@Quad RHEL7.3beta]$ rpm -qlp kernel-3.10.0-493.el7.x86_64.rpm | 
grep ath10

/lib/modules/3.10.0-493.el7.x86_64/kernel/drivers/net/wireless/ath/ath10k
/lib/modules/3.10.0-493.el7.x86_64/kernel/drivers/net/wireless/ath/ath10k/ath10k_core.ko
/lib/modules/3.10.0-493.el7.x86_64/kernel/drivers/net/wireless/ath/ath10k/ath10k_pci.ko

So at this point I'd say if you can carry on using kernel-lt until 7.3 
is released, your device should then be natively supported.


Regards,

Phil

RHEL 7.3 came out on Aug 25. It _usually_ takes 2 months from a beta
to the GA release. So, RHEL 7.3 might be released near the end of
October. But it's anyone's guess.

Red Hat do not publish release schedules so we can only guess / estimate 
based on previous releases.


RHEL betas normally run for around 3-4 months before release of the 
finished product. The RHEL 7.3beta was announced 25th August, so I'd 
expect 7.3 to be released around the end of November / beginning of 
December, 2016.


Of course if you are running one of the clones expect a further delay 
based on how quickly they are able to rebuild and release their cloned 
product.


Hope that helps

[elrepo] skylake and nvidia

[Nicolas Thierry-Mieg]

Hi again,

as posted a short while ago, I have a new Acer Aspire E5-575G-55DE 
laptop and am trying to get C7 running on it.


This laptop has an intel i5-6200U with integrated HD Graphics 520. It 
also has an nvidia GeForce GTX 950M.
Installing kmod-nvidia and bumblebee as explained [1] results in the "Oh 
no! Something has gone wrong" screen. I suspect that's because the 
regular C7 kernel and xorg-x11-drv-intel don't support the intel 520.


Booting into kernel-lt, it seems the intel 520 works...? This is 
surprising because Farkas Levente's recent post to this list suggested 
that a newer xorg-x11-drv-intel should be needed, in addition to the 
newer kernel. But I have a bunch of OK-looking intel messages in 
/var/log/Xorg.0.log , and glxinfo says:

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Skylake ULT GT2

Question 1: does this mean the intel 520 works fully under kernel-lt? If 
not, what should I look at?



Assuming the intel GPU works under kernel-lt, I could then hope to get 
nvidia and bumblebee working. I've been using the elrepo nvidia drivers 
for ages, but I could use the nvidia-provided installer and hope it 
doesn't clobber anything (which I doubt...).

Question 2: any caveats here?

Finally I would need to get bumblebee working, otherwise the nvidia 
stuff is useless. However, bumblebee requires kmod-bbswitch...
Question 3: I guess I would have to rebuild bbswitch [2] for kernel-lt, 
but could I still use the elrepo-provided bumblebee ?



Thanks for any advice anyone can provide.
Regards,
Nicolas
