Hello Greg,

I even gave an example about general purpose distributions that build as
much as possible as a module. What more info do you think that is missing?
Exact systems that this is failing on would be great to have.
The exact system is a Snapdragon SC7180 based HP X2 Chromebook with latest
Fedora Rawhide image (kernel version 6.1-rc4). The reason why is timing out
is that the arm_smmu driver is built-in (CONFIG_ARM_SMMU=y) but it depends
on gpucc-sc7180 clk driver that's built as module (CONFIG_SC_GPUCC_7180=m).
Additionally, this fails on the Snapdragon SC8280XP based Thinkpad X13s
with 6.1-rc4 (and rc5), however, unlike Javier's setup, I *do* have
CONFIG_SC_GPUCC_SC8280XP=y, so it's already built in to the kernel.
Additionally, all DRM options =y, except for CONFIG_DRM_GEM_HELP=m and
CONFIG_DRM_DISPLAY_CONNECTOR=m.
I am hoping to find some time tonight after work to also test on my
SDM850 based Lenovo Yoga C630, as I believe my previous testing of 6.1
may have been hitting this but I did not have time to dig into what was
going on there.
