 Posted: Sun Mar 10, 2019 11:18 pm Post subject: noob doesn't understand graphics/audio drivers |
 |
|
I'm brand new to Gentoo and the kernel, followed the handbook and have read over some of the wiki but I'm still not wrapping my head around what's going on.
My problems:
1) I don't have sound.
2) I think I am running the graphics hardware with generic drivers, and I'd like to use the specific ones.
I'm not running X, and I have installed fbterm and managed to view videos on the framebuffer.
My hardware:
ASUS Z390i motherboard
i5 9600K with UHD 630 integrated graphics
I'm not sure about the sound. Mobo manual says "ROG SupremeFX S1220A". lspci says Intel Corporation Device a348
Graphics and sound are both (supposed to be) carried over HDMI
I've noticed in the output of lspci -v that the audio device has "Kernel driver in use: snd_hda_intel" while the VGA controller has no "Kernel driver in use" listing.
I have CONFIG_RM_I915=y and CONFIG_SND_HDA_I915=y
I thought i915 was a graphics driver? What is i965 and how does it relate?
Full output of lspci -v:

not_a_robot,
Welcome to Gentoo,
| lspci: | 00:02.0 VGA compatible controller: Intel Corporation Device 3e98 (prog-if 00 [VGA controller])
00:1f.3 Audio device: Intel Corporation Device a348 (rev 10) |
You have a single sound card. That makes things easier.
Normally the video card would have its own sound card built in.
You have only one digital output too.
| Code: | iec958:CARD=PCH,DEV=0
HDA Intel PCH, Generic Digital
IEC958 (S/PDIF) Digital Audio Output |
In alsamixer find the output with IEC958 or S/PDIF in its name and unmute it.
This will probably mute your analogue sound as snd_hda_intel cab do both the 44.1kHz sample rate for analogue and 48.0kHz rate for digital outputs but not both at the name time.
Sound cards are in two parts. The PIC interface part, in your case, controlled by snd_hda_intel and the CODEC that does all the IO. That's your "ROG SupremeFX S1220A"
Google says its a Realtek ALC1220. The kernel needs to support both parts.
Thats CONFIG_SND_HDA_CODEC_REALTEK in the kernel.
You may also need CONFIG_SND_HDA_CODEC_HDMI
To help with your graphics make friends with wgetpaste and put the output of dmesg and your kernel .config file onto a pastebin site.
Post the links here. They are far to big to fit into a post.

Thank you! I now have sound coming through the analog outputs but still nothing over HDMI. I have noticed in others' aplay -L outputs that HDMI will be listed, but mine is missing.
Here is dmesg http://dpaste.com/3SS1GTS
Here is .config http://dpaste.com/2NQG1Q5 |

| How do I select the kernel version? I just skimmed back over the handbook and couldn't find a reference to kernel version, so I'm not exactly sure how I wound up with 4.19. |

not_a_robot,
| dmesg: | [ 11.392782] snd_hda_codec_hdmi hdaudioC0D2: No i915 binding for Intel HDMI/DP codec

You do need snd_hda_codec_hdmi but it can't find your sound card.

You are indeed using a generic framebuffer device for your console.
Your kernel has so you should be using the framebuffer that provides.
Go with Jaglovers advice and update your kernel. This page lists all the hardware that the driver works with.
Your Device 3e98 is there too. As its not being used, that device ID is probably not listed in your kernel, so the driver will not bind to your device.
| Code: |
$ grep -i 3e98 -R /usr/src/linux/ |
on kernel-4.19.0 shows its not listed.
$ grep -i 3e98 -R /usr/src/linux-5.0.0-gentoo/ includes
| Code: | | /usr/src/linux-5.0.0-gentoo/include/drm/i915_pciids.h: INTEL_VGA_DEVICE(0x3E98, info), /* SRV GT2 */ \ |
That's the definition for your video device. Notice the 0x3E98.

Thanks to you both. I've compiled a 5.0.1 kernel and I can see in the dmesg output that both the intel graphics driver and the HDMI audio are beig referenced, so that's good, but as soon as the handoff occurs to the intel driver, the screen goes black. I'm able to get dmesg output and reboot from console by typing blind.

I installed read-edid and tried it with both the 4.19 and 5.0 kernel, with the same result.
| Code: | This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
Looks like no busses have an EDID. Sorry!
Attempting to use the classical VBE interface
Performing real mode VBE call

My monitor is actually a Samsung "Smart TV", maybe that has something to do with it.
How do I set this manually? I managed to set my framebuffer size manually in /etc/default/grub, maybe some setting I have in there (GRUB_GFXPAYLOAD_LINUX=keep?) is causing a problem.

not_a_robot,
Can you startx?
It might be a console only problem. That would be worth knowing.

Jaglover, that link and doc was productive. I wound up taking the following steps:
1) Build a custom EDID for 4K@60h using values pulled from the advanced calculator here: https://www.extron.com/product/videotools.aspx
This caused dmesg to show an attempt to load my '3840x2160.bin" for "DP-1".
2) Disable DP-1 and enable HDMI-A-1 on the kernel command liine.
Now dmesg reports finding HDMI-A-1 and loading 3840x2160.bin for it. However, the TV is still reporting "no signal".
3) Repeat step (1) for 30h and 24h. Same result.
4) Attempt to load predefined EDID for 1920x1280. Same result.
5) Omit all EDID data but enable HDMI-A-1 to see if it will read EDID this time. It doesn't,
6) On the assumption that I most likely got the EDID values wrong, I chat with Samsung support to see if I could get the EDID directly from them.
This was unhelpful. They claimed that Samung TVs don't use EDID because they are "plug and play." Requests to be forwarded to an engineer were deflected.
I can think of one thing to try next with regard to EDID, and that is to purchase an HDMI passthrough EDID emulator. Hopefully it doesn't come to that.
NeddySeagoon, I'll try after reinstalling X tonight. |

Wouldn't it be easier to pass video=<yourmode> to your kernel for testing? In case you are using Grub2 it is just a matter of hitting 'e' and adding the option you wish to test. Furthermore, you could try with some mainstream live distro, if it works then you can duplicate the setup.

Jaglover:
I gave it a try, no dice. `video=HDMI-A-1:3840x2160@60`
I tried to boot from an arch-linux livecd and the moment it switches graphics modes during boot, I see this: http://dpaste.com/1NC5182
It looks like it could be a horizontal sync issue; maybe I can get the EDID arch is trying to use and tweak it until it works?
NeddySeagoon:
`startx` was apparently successful, though I still didn't get any video output. I removed the kms.edid_firmware statement from my kernel command line to see if the video mode might be autodetected. My xorg log (http://dpaste.com/2VKNFHG) shows some hopeful signs, I think. The monitor still isn't getting its settings across, though, the 4k video mode isn't detected.
Kernel config is here:

Some things to check.
Do you really have HDMI-A-1 output? Is the above syntax correct?
Regarding your Xorg, you need to run an application on it, otherwise it will terminate. If you build Kodi frontend for instance, run Kodi on Xorg and it will stay up.

I'm reasonably sure I have HDMI-A-1. I tried HDMI-1 at first but this had no visible effect; using HDMI-A-1 causes some messages about it to appear in dmesg, as well as creating an entry in /sys/class/drm (or wherever they populate, I'm not in front of the machine right now).
I installed lxde and xorg in hopes that lxde would just be automatically selected as my wm. I'm not too familiar with X, (I always took it for granted on desktop systems and have spent the last few years doing my personal comptering on guiless devservers in the cloud anyway.) so I will need to poke around with it when I get home tonight and make sure I'm actually running something on Xorg.
In this case, though, Xorg seems to stay up - judging by the Xorg log. |

| I also tried with a different monitor - in this case, a handheld HDMI projector. Same result, same exact dmesg output (besides timestamps). |

not_a_robot,
It looks promising but ...
| Code: | [ 25.897] (II) modeset(0): Output HDMI-1 has no monitor section
[ 25.897] (II) modeset(0): EDID for output DP-1
[ 25.897] (II) modeset(0): EDID for output DP-2

There are no widescreen modes there, like you are only getting old VESA modes.
| Code: | | [ 26.588] (II) Server terminated successfully (0). Closing log file. |
suggests that Xorg worked properly but found nothing to do, so exited cleanly.
| Code: | | emerge twm xterm xclock -1av |
will get you the default test applications for Xorg.
Is | Code: | | [ 26.127] (II) modeset(0): Setting screen physical size to 270 x 203 |
the correct size, in mm for your display?
That's too small to be useful for a 4k display. Do you have another display device attached?
That EDID data, including the physical size, came from somewhere.
Looking at the preferred video drivers, you hawe
| Code: | [ 25.829] (==) Matched intel as autoconfigured driver 0
[ 25.829] (==) Matched modesetting as autoconfigured driver 1
[ 25.829] (==) Matched fbdev as autoconfigured driver 2
[ 25.829] (==) Matched vesa as autoconfigured driver 3
[ 25.829] (==) Assigned the driver to the xf86ConfigLayout
[ 25.829] (II) LoadModule: "intel"
For diagnostics only, turn on
[code]# CONFIG_FB_SIMPLE is not set[/code]Grub sets up a framebuffer. This option allows the kernel to draw on that framebuffer. The kernel will not do any framebuffer setup. It just draws on what it finds. It just might get you an image though.
[ 25.830] (WW) Warning, couldn't open module intel |
If you can get it, the output of dmesg will be useful.

I don't have any other displays attached - and the output size is definitely wrong. I baked the intel driver into the kernel instead of compiling as a module, which is probably why Xorg isn't finding the module.
