Changing the memory split might affect some applications that expect a
large address space. For example, if an application is making heavy
usage of mmap(), either to map files into memory, or to map some
hardware like a framebuffer, then it might run out of virtual space.
Ironically the reported error in that case would be "out of memory" even
if not all the physical memory is exhausted, while a system with less
RAM but a standard user:kernel split would allow such applications to
work properly. The first case might occur with gcc when compiling, or
more likely when linking, large applications. A full "git repack" on a
large repository is also likely to get less efficient (it can scale its
vm usage down but with some performance penalty). The second case can
be seen with the X server and high end graphic cards on X86 for example
(no idea if that would be the case on current ARM graphic hardware).
Yet, highmem carries some small overhead of its own. So if you know
that all the applications you need have a workset that always fits in a
reduced address space then it is more advantageous to use a 2G:2G
user:kernel split and keep highmem off.
Of course, if the system has 3G of RAM or more (think LPAE) then you
don't have much choice but to use highmem.

Question: does highmem impact performance as soon as it's turned on, or
only when actually using a lot of memory because the sliding window
needs to move back and forth?
I'm asking because I would prefer if we were to have highmem turned on
in all our kernels, even if not strictly required, as to have less
divergence across SoCs, but I don't know whether there's a performance
cost to it

Hmm ... seems the kernel upload ftbfs:
https://edge.launchpad.net/ubuntu/+source/linux-linaro/2.6.35-1006.11/+build/1964751
Anyone can take a look so we get images and hwpacks back ?
Thanks!

You get a tiny overhead as soon as you turn it on, whether or not there
is sufficient memory to make it useful. Is that measurable? I doubt it.
And when actually using lots of memory, if that memory is populated
through DMA (no bounce buffer required) then you may get no additional
overhead. That all depends on the hardware configuration.

I doubt it is measurable, but someone could bench it. A good bench
would be some native compilation with many files (lots of fork()'s and
IO).

Tim,
This fixes the build failure in 1006.11 (bug #643462) . Verified the
build in an armel-maverick schroot.
A build on a Beagle is still running as I write this.
Thanks,
John
