OK. AFAIK the choice of page size is up to the kernel -- for non-embedded mips64 systems, some distributions choose a 16KB. Not sure what counts as "original MIPS", but I expect most embedded MIPS systems prefer 4KB pages (which is the previous value for CeilingOnPageSize for MIPS). 1754130 4 ews-feeder 2021-04-26 02:04:10 -0700 Committed r276583 (237019@main): <https://commits.webkit.org/237019@main> All reviewed patches have been landed.

FWIW in Debian we have a downstream patch to use 16KB pages in MIPS64, it seems that Loongson CPUs don't support 4KB pages. 1760736 7 angelos 2021-05-17 06:59:57 -0700 (In reply to Alberto Garcia from comment #6) [...] > FWIW in Debian we have a downstream patch to use 16KB pages in MIPS64, > it seems that Loongson CPUs don't support 4KB pages.
