Meh, not large.  Simply doubling the space supported to 1TB would be
an easy first step and -- given someone with a machine to test it --
should work out any kinks in the use of the direct map.  40 physical
bits in the professed default for long mode, so it's really what the
default should be.  Doing the second step to full dynamic would then
be about getting the ASM right when values are not longer constant.

We only allocate a single PML4 slot for the direct map on amd64, so
it's currently limited to seeing 2^39 == 512GB.

To expand that, the size and base-slot/address of the direct map
really need to be made variable, based on the number of physical
address bits supported by the CPU (as found by CPUID), preferably then
clamped by the range of the actual memory installed, and then set up
in locore.S and pmap.c

Thanks for the explanation of the memory limit.  I'm not needing a
system with more than 512G yet, but how much of a project would it
be to dynamically expand to whatever?

We only allocate a single PML4 slot for the direct map on amd64, so
it's currently limited to seeing 2^39 == 512GB.

To expand that, the size and base-slot/address of the direct map
really need to be made variable, based on the number of physical
address bits supported by the CPU (as found by CPUID), preferably then
clamped by the range of the actual memory installed, and then set up
in locore.S and pmap.c

Hi mark,

I saw that befor and did the steps for python like there and I can thest
my script by chroot but I cant really figure what to do in the httpd
config to get my script called when I surf it to it over the browser.

Markus,

Here's what the key portion of the httpd.conf file contains:

# A name-based "virtual" server
server "chrome.hydrus.org.uk" {
alias "chrome"
listen on * port 80

root "/hydrus/data"
log access "hydrus-access.log"
log error "hydrus-error.log"

location "/cgi-bin/*" {
fastcgi
root "/hydrus/data"
}

}

Hope that helps.
