[-- Attachment #1 --] > Not all architectures have PAGE_SIZE of 4K. Not going back to the historic > arches, and out of tree patches for x86, I believe that arm64 has in-tree > support for 16K pages. imp@ alluded to that in the revision (https://reviews.freebsd.org/D50124) so, back then, I checked in-tree but could not find any hint anywhere (code, kernel configs) that PAGE_SIZE would actually be set to 16k in public configs, hence the commit message (with "unchanged for all architectures", I meant in fact unchanged for the official artifacts we build). I see some support for PAGE_SIZE != PAGE_SIZE_4K. For such experiments, this commit should certainly help. -- Olivier Certner [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQIzBAABCQAdFiEEmNCxHjkosai0LYIujKEwQJceJicFAmgmCrEACgkQjKEwQJce Jic0CQ//RyJuXps3VD2S/rnoXprQ0foPPag8RAvt18zVg+/MYINbkMoJa0REOCsV MVmFJSFk/59GhpqNwZ846IUxX3OpOjnkFKS53pNfRP0cMzy02HYg2fC0XbeGrJay xUW32czNDQjFxCSkKlhQCUbbs2tueKi2EoapMMpfxdd2xAGVTBNXQfYdrcO/VLjU C+fqfSbJXm9zCRgBeDQ3Dxw8Y+fOOGRmWo3HgFH59lvpHV4dtkbJbUGscauJN6CN G39dMpzzDeIiVGTGNBNKP+YbTaAtVy9GH2hbT9dW5awUKLG34Q2N4GJ9U0+MHNrx qeddTg71KAO9Ynd2PAHlJSq8/FNJna0Vi+Qngffh98+WSId3HFrD9uvLCYf0E1Fk +1Japr5LurNL2JU2V2GZ457yAABbpaPMPubrr+EnD9APX18uJx6UZ2p3hvUU6QpV dV0WYxP9+GjHY+CjctmFpUizFqwM6ypWZ1GoAInBIAbvJabmp0KkW0aMD4gw6XxW qbT0G4DVJ5YdMYoAqequXmdelQIID5apLXbex14cQokcJ0W/8zaWL2Pg/RoM6dPZ 1SPDp0hmcrpOPRmcb4+Qbz8V9OOAEr3wIagj3dqNWLS+TAJzZzV2Yn0B3DQtvTUh da0T14h/gz27UShWYY9dz268ZzgEkoHOmBFiBXWlXfHpUvFkwag= =CMad -----END PGP SIGNATURE-----help
