Support page size > 4K in jemalloc #5244
Description
Description
Some ARM processors have a page size other than 4k (16k for example). lighthouse bn is unable to launch on those processors, with the error: <jemalloc>: Unsupported system page size
This is a know issue as can be seen here:
As explained in the above issue, jemalloc page size is a compile time option, but higher ones are ok to use on lower page sizes, the other way round doesn't work.
My suggestion would be to increase the page size to 16k during the jemalloc compilation phase on the ARM docker images. As it's officially supported to have it higher, this shouldn't break anything, just make 16k systems work.
Version
v4.6.0
Present Behaviour
On launch of the BN: : Unsupported system page size
Expected Behaviour
Just work normally. Page size shouldn't be an issue for normal applications.
Steps to resolve
Right now the only way is to switch your kernel to a 4k page size. That's quite intrusive.
