This is forked as a new /sbin/sh (pid 3) which crashes, probably due to MMU DPROT issues. 161.1Spalle- 64-bit kernel support 171.1Spalle- 32-bit kernel support 181.2Spalle- libkvm 191.2Spalle- ofwboot: tlb_init_sun4v() hardcodes number of slots to 64 201.17Spalle- locore.s: sun4v_datatrap missing implementation for trap level 1 211.5Spalle- check build without SUN4V defined 221.13Spalle- replace relevant references to %ver with GET_MAXCWP 231.6Spalle- pmap_mp_init(): sun4v missing handling 241.6Spalle- replace constructs like "wrpr %g0, PSTATE_KERN, %pstate" with NORMAL_GLOBALS 251.6Spalle- replace constructs line "wrpr %g0, PSTATE_INTR, %pstate" with ALTERNATE_GOBALS 261.7Spalle- sun4v tsb no need to lock... per cpu... anyway... 271.7Spalle- ci_tsb_desc->td_ctxidx: -1 or 1? 281.14Spalle- MP support - currently bypassed in pmap_bootstrap() for sun4v 291.12Spalle- vpci.c/vpcivar.h: cleanup FIXMEs 301.16Spalle- interrups not handled properly (com at ebus only...) 311.18Spalle- mpt(4) complains: mpt0: Phy 0: Link Status Unknown 321.20Spalle- man pages for drivers imported from OpenBSD lke vpci, vbus, cbus, vdsk, ldc etc. 331.20Spalle- vdsk and ldc drivers: code maked with OPENBSD_BUSDMA - make the bus_dma stuff work properly 341.22Spalle- vbus.c: handle prom_getprop() memory leaks 351.25Spalle- locore.s: rft_user (sun4v specific manaul fill) - seems to work, but is it good enough (compared to openbsds rft_user? 361.27Spalle - platforms tested so far: 371.27Spalle -- qemu sun4v/niagara - crash in init process relaed to fork (stack?) 381.27Spalle -- T2000 - mmu fault somewhere 391.27Spalle -- T5 - stickcmpr is not properly initialized ??? 40
