dual amd quad core 16G Ram

[Ben Adams-3]

I'm setting up a server.  I have dual quad core with 16G of ram.  I'm
looking to run 4.4.

the fallowing line in change list:
Make amd64 machines be able to use more than 4G ram, and crank the MAXDSIZ
to allow allocations/mmap() up to 8G

Is this per cpu not core?

Thanks

for now amd64 is limited to 4G total. we lack bounce buffers for more
so far.

thought you can set bigmem variable and try running with iommu:

boot> boot -d
w bigmem 1
c

this is on amd64 only.  and as 'boot -d' was fixed about a week ago,
you certainly want to get a snapshot (and it contains some more fixes
anyway).
