Hi all,
A number of you may have noticed the recent flurry of activity,
leading to stuff
like bigmem being turned on.. Some more good stuff is coming soon (my amd64
at my house is using 7 gigabyes of memory for buffer cache, and I'm doing builds
without touching disks..). Some really
This diff moves the buffer cache to only be allocated out of dma'able
memory, along with a few pieces (flags) that I will need for the next step
of allowing it to touch high memory.
Appears to behave well for me under load and builds survive it with
the buffer cache cranked up.
I would like
The driver itself could happily allocate it's own little crappy bounce
buffer.
