Hi there,
as per $SUBJECT, the most recent kernel from Kernel:stable obsoletes
drm-kmp-default <= 4.12
which results in removal of drm-kmp-default-4.9.33_k4.4.126_48-13.3 on an openSUSE_Leap_42.3 system. I checked kernel-default.spec in OBS and it has this indeed:
# SLE12-SP3 / Leap 42.3 %obsolete_kmp drm 4.12
I am still running several systems with Leap 42.3 and always want to be able to also test newer stable kernels, however this change would render most of my systems as useless as they need the drm-kmp-default package for dealing with the Intel HW and graphics adapter (see one example below) and when running the distro kernel.
...render most of my systems as useless... This is actually a bit harsh. I just removed drm-kmp-default on all relevant systems and booted the distro kernel (4.4.172-86-default); useless to say that "modeless" doesn't work, but graphics can still be run at an acceptable speed using the Intel driver for X. Even the console resolution stays at a reasonable level on the systems with a Haswell CPU, only the ones with a Kaby Lake CPU now fall back to an 80x25 console... which is acceptable for emergency cases. HW acceleration for graphics is not available on Kaby Lake, too, but the CPU can still render high resolution movies at normal speed (with all cores running at appr. 70% clock speed though, compared to a low 1 digit number on the newer kernels).
May I ask why it has been introduced? Former versions (4.20.8 only obsoleted the package older than 3.7_3.1) did not appear to have an issue with it being installed. To be honest, does it play a role at all for any kernels from Kernel:stable? I always thought that drm-kmp brings a backport of some newer modules which are otherwise too old for the elder kernels.
I'd still like to know why it has to go...
I would find it unfortunate, if I cannot run the newer kernels anymore on my 42.3 systems...
