TODO revision 1.26
1 /* $NetBSD: TODO,v 1.26 2018/04/11 19:44:47 palle Exp $ */ 2 3 Things to be done: 4 5 common: 6 - make %g6 point to curcpu 7 - make %g7 point to curlwp 8 - change run-time checks for cpu type to function pointers 9 10 sun4u: 11 - GENERIC.UP kernel hangs on v445 (missing interrupt?) 12 13 sun4v: 14 - current status: The kernel boots and starts the init process (pid 1) 15 which spawns /bin/sh (pid 2). This is forked as a new/bin/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 37
