** Attachment added: "acpidump.txt"
https://bugs.launchpad.net/bugs/1953613/+attachment/5546278/+files/acpidump.txt
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Description changed:
The current versions of gpiod, libgpiod-dev and libgpiod2 (1.6.2-1) use
version 1 of the GPIO character device API. However, they cannot work
because the interface is disabled in the default kernel (tested with
5.13.19). After rebuilding the kernel with the option
CONFIG_GPIO_CDEV_V1=y, the gpiod tools work as expected.
+ Thanks to Marek Szuba, who reported the same bug for Gentoo
+ (https://bugs.gentoo.org/807334), pointing me in the right direction.
What I expect to happen:
- $ gpiodetect
+ $ gpiodetect
gpiochip0 [0-003c] (8 lines)
$ gpioinfo
gpiochip0 - 8 lines:
- line 0: unnamed unused output active-high
- line 1: unnamed unused output active-high
- line 2: unnamed unused output active-high
- line 3: unnamed unused output active-high
- line 4: unnamed unused output active-high
- line 5: unnamed unused output active-high
- line 6: unnamed unused input active-high
- line 7: unnamed unused input active-high
+ line 0: unnamed unused output active-high

+ line 3: unnamed unused output active-high
+ line 4: unnamed unused output active-high
+ line 5: unnamed unused output active-high
+ line 6: unnamed unused input active-high
+ line 7: unnamed unused input active-high
$ gpioget gpiochip0 0
1
What actually happens:
$ gpiodetect
gpiochip0 [0-003c] (8 lines)
$ gpioinfo
gpioinfo: error creating line iterator: Invalid argument
$ gpioget gpiochip0 0
gpioget: error reading GPIO values: Invalid argument
