via the Configuration Port, so restructure the code a little
to allow for them, and list at least one other system that does
(anything based on AMD Elan SC520).
XXX We don't actually check for Elan SC520 yet.
Use %lld instead and cast the args to (long long) explicitly.
I'm not sure about our policy vs. the C99 format string macros in
basesrc - should we use those here?
documentation:
- Remove "mainbus" altogether.
- The new root is "plb" - the Processor Local Bus.
- Attached to this is the "opb" - the On-chip Peripheral Bus, to which
all the on-chip devices are attached (except the cpu and pci host
bridge).
- Port-specific code can pass an array of 'struct plb_dev' to
config_rootfound() to attach extra devices to the plb. The walnut
port attaches a "pbus" (Peripheral Bus) in here for the RTC and
pc keyboard controller to attach to.
There is still much 405GP specific code; the next round of changes will
generalise this to enable easier support for other 4xx CPUs.
driver attaches where "pchb" would normally attach (it matches at a
higher match priority). The "elansc" driver currently provides support
for the watchdog timer built-in the SC520.
Thanks to Jasper Wallace for laying the ground-work for this (most
notably by providing a work-around for a watchdog-related bug in the
SC520).
to deal with aliasing of regular memory pages, because many processors don't
support it.
Now, the pmap marks all mappings of a page that has any non-equivalent
aliasing and any writable mapping, and the fault handlers watch for this
and flush other mappings out of the TLB and cache before (re)entering a
conflicting mapping.
When a page has non-equivalent aliasing, only one writable mapping at
a time may be in the TLB and cache. If no writable mapping is in the
TLB and cache, any number of read-only mappings may be.
The PA7100LC/PA7300LC fault handlers have not been converted yet.
EXCLUDE_UNENCRYPTED bit in the WI_RID_P2_ENCRYPTION value if we are
in shared key mode. Symbol cards, just to be different, supposedly
always want the EXCLUDE_UNENCRYPTED bit set (confirmed with the
Linux orinoco and spectrum24 drivers).
* Flesh out the Host-AP WEP transmit side. Note this does not yet
work properly; the frame as seen by the receiver FCS's incorrectly.
Both changes from OpenBSD. Not confirmed whether or not Host-AP WEP
works with OpenBSD (mail sent to millert).
This version works on both 26-bit and 32-bit machines. For large copies,
it's up to three times as fast as the old arm32 version and five times as
fast as the old arm26 version. For small copies it seems to be even faster
(getrusage() is apparently over ten times faster on an ARM610).
Hooray for Allen!
