 Posted: Sat Aug 05, 2023 12:31 pm Post subject: static /dev with nvme |
 |
|
I have a laptop with an nvme ssd(not this one).
I plan to do an old-fashioned gentoo on it.
However, I see no nvme entries it /usr/src/linux/Documentation/admin-guide/devices.txt.
Does this mean that nvme cannot be done statically(at least without cheating and looking an /proc/devices)?

It is at the end of devices.txt without explicit naming of nvme:
| Code: | # ll /dev/nv*
crw------- 1 root root 247, 0 4. Aug 12:32 /dev/nvme0
brw-rw---- 1 root disk 259, 0 4. Aug 12:32 /dev/nvme0n1
brw-rw---- 1 root disk 259, 1 4. Aug 12:32 /dev/nvme0n1p1
brw-rw---- 1 root disk 259, 2 4. Aug 12:32 /dev/nvme0n1p2
brw-rw---- 1 root disk 259, 3 4. Aug 12:32 /dev/nvme0n1p3 |
(look at major and minor number) |

You are right. I just searched for nvme.
| Code: | 234-254 char RESERVED FOR DYNAMIC ASSIGNMENT
Character devices that request a dynamic allocation of major number will
take numbers starting from 254 and downward. |
| Code: | 259 block Block Extended Major
Used dynamically to hold additional partition minor
numbers and allow large numbers of partitions per device |
Just as I worried.

stefan11111,
I do it. My NVMe major device number has not changed in two years.
Thinking back 10 years to when I reverted to a static /dev, its changed exactly once.
If you use an initrd, you can discover the new numbers in the shell.
if not, it a bit harder.
It happens with a kernel change, so choosing the old kernel in the boot menu gets you booted.

Your lsmod and lspci is from a system you have booted (and not from your kernel config). Here I see what is missing in your kernel config: Intel's Volume manager device:
| Code: | # CONFIG_VMD is not set
0000:00:0e.0 RAID bus controller [0104]: Intel Corporation Volume Management Device NVMe RAID Controller [8086:9a0b]
Subsystem: Acer Incorporated [ALI] Volume Management Device NVMe RAID Controller [1025:1539]
Kernel driver in use: vmd
Kernel modules: vmd |

I am also not able to use the laptop's keyboard. I can use an usb keyboard though.
I also don't see the wifi card or the usb tethering interface in ifconfig.
All these were working on the livecd.

stefan11111,
| Code: | 0000:00:14.3 Network controller [0280]: Intel Corporation Tiger Lake PCH CNVi WiFi [8086:43f0] (rev 11)
Subsystem: Rivet Networks Tiger Lake PCH CNVi WiFi [1a56:1652]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi |
make iwlwifi a kernel module as it needs firmware.
It will also need the rest of the wifi stack.
The keyboard may be an I2C device, so you need
| Code: | 0000:00:15.0 Serial bus controller [0c80]: Intel Corporation Tiger Lake-H Serial IO I2C Controller #0 [8086:43e8] (rev 11)
Subsystem: Acer Incorporated [ALI] Tiger Lake-H Serial IO I2C Controller [1025:1539]
Kernel driver in use: intel-lpss
Kernel modules: intel_lpss_pci
0000:00:15.1 Serial bus controller [0c80]: Intel Corporation Tiger Lake-H Serial IO I2C Controller #1 [8086:43e9] (rev 11)
Subsystem: Acer Incorporated [ALI] Device [1025:1539]
Kernel driver in use: intel-lpss
Kernel modules: intel_lpss_pci |
That's not enough on its own either. Pastebin dmesg where it works.

stefan11111,
| Code: | | [ 0.327187] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input0 |
That's PS/2 internally, so should just work ... unless you don't have PS/2 support in your kernel.

Who has support for PS/2 just laying around in the kernel?
Enabled it now and keyboard works.
The touchpad doesn't work(tested with xorg and cat /dev/input/mice).
Sound doesn't work, though speaker-test and alsamixer detect the sound card. Sound works in the livecd.

| I have it enabled, because laptops have an odd history of using PS/2 internally, even when the system is sealed so well that you could never coldplug (much less hotplug) any PS/2 devices. |

stefan11111,
I do. The hardware is all the chipsets still because it costs more to take it out than it save on silicon die area.
There have not been any physical PS/2 connectors on system for a long time, but odd things still use the protocol, keyboards, mice, touch pads/screens.
My X560 chipset sill has floppy, IDE and ISA interfaces internally. The ISA may well be used for sensors.
Your touchpad does not appear in the dmseg you shared earlier.
The kernel has a menu for vendor specific laptop extensions. I don't know if there is an Acer option but if so, you probably need it.

I got usb tethering to work by following the wiki.
I can live with no touchpad.
That leaves sound.
The soundcard shows up and I can change the volume in alsamixer.
However, no sound comes out.
Sound works fine in the livecd.

You have two sound cards

Your analogue sound card, Card 0, Device 0 is the default. Is that what you want?
With a static /dev, the /dev/snd/* device minor numbers may not agree with what | Code: | | ls /sys/dev/char/ -l |
has to say about major device 116.
You need to fix /dev/snd/* to make them agree.
To make the video card sound work, you will need to use dynamic minor device numbers for sound.

I did MAKEDEV audio to create those /dev/snd nodes and fixed permissions.
The sound card shows up in aplay -l and alsamixer, but no sound comes out.
I tried to test it with udev, enabling devtmpfs, everything was the same.
If I plug in my usb headset, it works fine after I set /etc/asound.conf.

No need for that.
