Where do you want architecture-specific bugs to be filed? Is there some
component in Bugzilla for ppc64le issues?
WebKit disables its heap security features ppc64le due to the 64 KB page
size. But reporting the bug to upstream would be pointless, because
upstream does not care about ppc64le. Reporting the bug against
webkit2gtk3 on Red Hat Bugzilla would mean reporting to myself, also not
GPUs also require firmware blobs, we can not really see inside them. If
there is something in the blob that only works on 4k then we have trouble.
These issues tend to crop up from time to time in different places, not
just the kernel. I started a thread here with some of them. For
example, Firefox WebRTC with my Elgato Camlink was not working on 64k
but it is fine on 4k.
Is there any way to report on how many packages call getconf PAGESIZE or
getconf PAGE_SIZE during the build? There are not many of these but
they have different risks if people are swapping between 4k and 64k kernels.
Most packages compiled on one type of kernel will run on the other type
but there could be a very small number that have to be recompiled if the
Fedora kernel changes down to 4k.
Regardless of the packages above, I still think the Btrfs issue is the
biggest surprise for people and it is worse because it is the default
filesystem now. People can reboot into a new kernel but they may not be
able to easily reformat their disks after mkfs at 64k.
