under big endian.
2. ":set octal" with nonprintable character causes nbwcurses move error.
3. moving (big)words by wW/eE/bB can't handle non-ascii characters.
4. toggle uppercase/lowercase by ~ can't handle non-ascii characters.
5. don't feed CHAR_T(=wchar_t) to is* function directly.
is* funcs with over UCHAR_MAX value may cause undefined behavior.
some ctype implementation(such as FreeBSD) return unexpected
result(same result as isw* func).
6. using non-ascii digit character with count/line number of ex/vi
command may causes unexpeced result.
pryo still isn't fully working, but i'm able to talk to disk and com
properly. bge, ohci/ehci, aceride and wm (pcie card) interrupts
are not working yet.
- handle setting tsb size in the ptsb via IOMMU_TSBSIZE_IN_PTSB (partly from
openbsd)
- fix IDB_INFO for systems without a STC that fault on accesses to the
flush register (like pyro)
- move iommu_reset() to the end of iommu_init()
- use IOMMUREG_WRITE() in a few places
- add a missing membar_lookaside() (from openbsd)
- if pmap_extract() on the flush buffer fails, disable flushing (from openbsd)
- flush the pyro-style iommu when IOMMU_FLUSH_CACHE is set (partly from openbsd)
- clear up a bit of debugging code so it spew a little less (sometimes you will
get kernel lock spinouts due to long scrolling printfs)
- use __func__ in several places
clean up some debug code. clean up the DPRINTF() code, and expand
the interrupt mapping debug code to match schizo and psycho.
set IOMMU_TSBSIZE_IN_PTSB, and if oberon, IOMMU_FLUSH_CACHE.
disable the STC explicitly.
and specify that usb_dma attribute to dev/usb/usb_mem.c.
usb_mem.c uses bus_dma(9) for DMA memory allocation,
but non-DMA capable USB host controllers like slhci(4)
doesn't need them at all, and some ports don't bother to
prepare MD bus_dma(9) implementation (yet).
Discussed on current-users
http://mail-index.NetBSD.org/current-users/2011/03/13/msg015995.html
and usb_dma attribute is suggested by bouyer@.
Tested by kiyohara@ on mmeye with slhci at pcmcia.
usb_mem.c provides functions for DMA memory allocation
that is required by DMA capable host controllers only,
but MALLOC_DEFINE() isn't DMA specific and could be required
by any USB drivers.
Discussed on current-users.
