Modified Files: src/sys/arch/mips/include [netbsd-6]: pmap.h src/sys/arch/mips/mips [netbsd-6]: pmap.c pmap_segtab.c Log Message: Pull up following revision(s) (requested by skrll in ticket #1068): sys/arch/mips/mips/pmap.c: revision 1.214 sys/arch/mips/include/pmap.h: revision 1.63 sys/arch/mips/mips/pmap_segtab.c: revision 1.8 Deal with incompatible cache aliases. Specifically, - always flush an ephemeral page on unmap - track unmanaged mappings (mappings entered via pmap_kenter_pa) for aliases where required and handle appropriately (via pmap_enter_pv) Hopefully this (finally) addresses the instability reported in the following PRs: PR/44900 - R5000/Rm5200 mips ports are broken PR/46890 - upcoming NetBSD 6.0 release is very unstable/unusable on cobalt qube2 PR/48628 - cobalt and hpcmips ports are dead To generate a diff of this commit: cvs rdiff -u -r1.61.8.1 -r1.61.8.2 src/sys/arch/mips/include/pmap.h cvs rdiff -u -r1.207.2.2 -r1.207.2.3 src/sys/arch/mips/mips/pmap.c cvs rdiff -u -r1.4.2.1 -r1.4.2.2 src/sys/arch/mips/mips/pmap_segtab.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
