 1.1  palle
 1.1  palle Things to be done:
 1.1  palle
 1.5  palle common:
 1.5  palle - make %g6 point to curcpu
 1.5  palle - make %g7 point to curlwp
 1.8  palle - change run-time checks for cpu type to function pointers
 1.5  palle
 1.1  palle sun4u:
1.10  palle - GENERIC.UP kernel hangs on v445 (missing interrupt?)
 1.1  palle
 1.1  palle sun4v:
1.26  palle  - current status: The kernel boots and starts the init process (pid 1)
1.28  palle    which spawns /sbin/sh (pid 2). This is forked as a new /sbin/sh (pid 3)
1.28  palle    which crashes, probably due to MMU DPROT issues.
1.28  palle    Looks like the user process tries to write to the stack as part of a save
1.28  palle    instruction since cansave is zero. This causes a DMMU PROT trap (0x6c) which
1.28  palle    calls sun4v_tl0_dtsb_prot which calls sun4v_datatrap which calls TRAP_SETUP().
1.28  palle    This macro has code that does a save instruction, again to the user stack,
1.28  palle    which again causes a MMU DPROT trap...
 1.1  palle - 64-bit kernel support
 1.1  palle - 32-bit kernel support
 1.2  palle - libkvm
 1.2  palle - ofwboot: tlb_init_sun4v() hardcodes number of slots to 64
1.17  palle - locore.s: sun4v_datatrap missing implementation for trap level 1
 1.5  palle - check build without SUN4V defined
1.13  palle - replace relevant references to %ver with GET_MAXCWP
 1.6  palle - pmap_mp_init(): sun4v missing handling
 1.6  palle - replace constructs like "wrpr %g0, PSTATE_KERN, %pstate" with NORMAL_GLOBALS
 1.6  palle - replace constructs line "wrpr %g0, PSTATE_INTR, %pstate" with ALTERNATE_GOBALS
 1.7  palle - sun4v tsb no need to lock... per cpu... anyway...
 1.7  palle - ci_tsb_desc->td_ctxidx: -1 or 1?
1.14  palle - MP support - currently bypassed in pmap_bootstrap() for sun4v
1.12  palle - vpci.c/vpcivar.h: cleanup FIXMEs
1.16  palle - interrups not handled properly (com at ebus only...)
1.18  palle - mpt(4) complains: mpt0: Phy 0: Link Status Unknown
1.20  palle - man pages for drivers imported from OpenBSD lke vpci, vbus, cbus, vdsk, ldc etc.
1.20  palle - vdsk and ldc drivers: code maked with OPENBSD_BUSDMA - make the bus_dma stuff work properly
1.22  palle - vbus.c: handle prom_getprop() memory leaks
1.25  palle - locore.s: rft_user (sun4v specific manaul fill) - seems to work, but is it good enough (compared to openbsds rft_user?
1.27  palle  - platforms tested so far:
1.27  palle  -- qemu sun4v/niagara - crash in init process relaed to fork (stack?)
1.27  palle  -- T2000 - mmu fault somewhere
1.27  palle  -- T5 - stickcmpr is not properly initialized ???
