[libcamera-devel] Failed to commit atomic request: Invalid argument

[Eric Curtin]

Hi Guys,

Still struggling to get the display working on 2 different fedora 34 laptops.
The first problem I run into is:

"Failed to commit atomic request: Invalid argument"

This occurs when drmModeAtomicCommit is called with  these flags set:

DRM_MODE_ATOMIC_ALLOW_MODESET | DRM_MODE_PAGE_FLIP_EVENT |
DRM_MODE_ATOMIC_NONBLOCK

in the drmFlags.

Then we go from:

drmModeAtomicCommit -> DRM_IOCTL -> drmIoctl -> ioctl

and return EINVAL. Anybody have an idea what could be going wrong here?
Are the flags ok in this case etc.?

Some version info and other info on how I am running this:

$ rpm -qa | grep libdrm
