This does NOT identify the devices, merely indicates the
presence of devices at certain addresses. Tested on ichsmb
and nfsmb - other SMBus devices will need to ensure the
proper bus type is set. (I2C_TYPE_SMBUS)
From Nicolas Joly, via Paul Goyette, in PR#36744.
transfer as a write to ensure the memory is writable before starting any
transfer. The fault status information does not reflect this in the 'read'
status bit (i.e. it shows up as a read access), so faults with a RMW access
to non-writable memory was not getting the correct protection. The page would
be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts
to execute a RMW access to a data page, which is read-only because it's CoP
Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer
and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write
fault bits, and both are set on a RMW access and the trap code was checking
the write status bit.
Fixes PR#36848.
it is easier to keep kernel configuration files up-to-date.
While we are here, disable a few compat options - NetBSD 1.5 has been
a while.
Tested on a Macintosh SE/30 with ae(4) ethernet card.
(thanks god for KMEMSTATS).
- sysmon_envsys_register: add all objects in the dictionary without any
lock, at this point the sme device hasn't been added into the list
and it's safe.
- Add sysmon_envsys_destroy_plist(prop_array_t) that destroys all objects
associated with a device and use it on sysmon_envsys_unregister() and
sysmon_envsys_register() if there's any error.
Thanks to Mindaugas Rasiukevicius (rmind@) for the great comments/ideas.
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.
