all devices on the bus are really reset.
- Block interrupts on Bus Reset, and check it periodically until the
reset is released. On some 32UDE devices (probably the earlier ones)
the RST line looks unstable without the termination power and may
suffer ~continuous Bus Reset interrupts.
- Change number of scatter/gather segments from 16 to 17, to allow
non-page-aligned 64KB transfer on 4KB/page platforms.
- make sure to set HD_ROW1_ADDR before putting characters at the first line
in hd44780_ddram_redraw()
- use memmove(9) rather than bcopy(9) for possibly overlapped copies
- the value of the ATA error register would be computed wrongly, leading to
bogus error values reported to wd(4)
- the channel would not always be restarted after an error, so the next
command would not be handled by the controller
- a timeout condition would not be properly reported to wd(4), leading
to a short transfer instead of a reset/retry
these bugs would cause a AHCI SATA channel to be stalled (no more command
processed) after a "ID not found" or "Aborted command" error reported by the
drive.
the limit in some LM chips.
- Add the lm_detach() function that stops/destroys the callout and
unregisters the driver from the sysmon_envsys(9) framework.
error = (cmd == SIOCADDMULTI) ?
ether_addmulti(ifr, &sc->sc_ec) :
ether_delmulti(ifr, &sc->sc_ec);
if (error == ENETRESET) {
to this,
if ((error = ether_ioctl(ifp, cmd, data)) == ENETRESET) {
which does the same thing.
(A bazillion is a very large number. This seems to make the i386
ALL kernel smaller by 3kB to 4kB.)
Use ifreq_getaddr() twice in es(4).
Whitespace nits.
identify sockaddr_dl abuse that remains in the kernel, especially
the potential for overwriting memory past the end of a sockaddr_dl
with, e.g., memcpy(LLADDR(), ...).
- Moved to x86/pci, so that EM64T systems running NetBSD/amd64 can use it.
- Added support for the TCO on ICH6 or newer chipsets, adapted from
FreeBSD.
- Added timecounter support for the power management timer, adapted from
OpenBSD.
- Plus some misc/cosmetic changes.
Thanks to yukonbob on irc@freenode for testing the TCO part on ICH4-M.
Tested by me with ICH7 too.
