1 /* $NetBSD: TODO,v 1.27 2018/10/05 19:53:47 palle Exp $ */ 2 3Things to be done: 4 5common: 6- make %g6 point to curcpu 7- make %g7 point to curlwp 8- change run-time checks for cpu type to function pointers 9 10sun4u: 11- GENERIC.UP kernel hangs on v445 (missing interrupt?) 12 13sun4v: 14 - current status: The kernel boots and starts the init process (pid 1) 15 which spawns /sbin/sh (pid 2). This is forked as a new /sbin/sh (pid 3) which crashes, probably due to MMU DPROT issues. 16- 64-bit kernel support 17- 32-bit kernel support 18- libkvm 19- ofwboot: tlb_init_sun4v() hardcodes number of slots to 64 20- locore.s: sun4v_datatrap missing implementation for trap level 1 21- check build without SUN4V defined 22- replace relevant references to %ver with GET_MAXCWP 23- pmap_mp_init(): sun4v missing handling 24- replace constructs like "wrpr %g0, PSTATE_KERN, %pstate" with NORMAL_GLOBALS 25- replace constructs line "wrpr %g0, PSTATE_INTR, %pstate" with ALTERNATE_GOBALS 26- sun4v tsb no need to lock... per cpu... anyway... 27- ci_tsb_desc->td_ctxidx: -1 or 1? 28- MP support - currently bypassed in pmap_bootstrap() for sun4v 29- vpci.c/vpcivar.h: cleanup FIXMEs 30- interrups not handled properly (com at ebus only...) 31- mpt(4) complains: mpt0: Phy 0: Link Status Unknown 32- man pages for drivers imported from OpenBSD lke vpci, vbus, cbus, vdsk, ldc etc. 33- vdsk and ldc drivers: code maked with OPENBSD_BUSDMA - make the bus_dma stuff work properly 34- vbus.c: handle prom_getprop() memory leaks 35- locore.s: rft_user (sun4v specific manaul fill) - seems to work, but is it good enough (compared to openbsds rft_user? 36 - platforms tested so far: 37 -- qemu sun4v/niagara - crash in init process relaed to fork (stack?) 38 -- T2000 - mmu fault somewhere 39 -- T5 - stickcmpr is not properly initialized ??? 40
