Now looking in the doc source, I see that the "780MB" value from above is 
architecture-dependent too.
While 780MB seems realistic for amd64 to me, I wonder if the other values can
be up-to-date:

amd64:minimum_memory=780
arm64:minimum_memory=260
armel:minimum_memory=80
armhf:minimum_memory=190
i386:minimum_memory=485
mips:minimum_memory=85
mips64el:minimum_memory=345
mipsel:minimum_memory=170
ppc64el:minimum_memory=64
s390x:minimum_memory=44

In the most eye-catching case of s390x, my proposal would mean, to change
the value in the guide from 44 to 512MB !
That leads to the question, if the new situation after my changing would be 
wrong, or if the doc was wrong in the past?
And, if a generic value for all archs is realistic and makes sense at all?


My current plan would boil down to the attached patch.


Holger

Ah, yes, that's part of the lowmem testing.

The doc probably just ended up wrong by just not getting updated,
because we don't have people who both care about updating them, and have
access to the hardware or know the qemu tricks to test all archs.

I see that in the lowmem package,
bbb4ed4c4da20d585cf30ceba9f0987173d3ac70 raised the default levels from
32MB/64MB to 120MB/155MB, that being the minimum numbers that were
actually seen to work on at least some arch.

> And, if a generic value for all archs is realistic and makes sense at all?

Probably not, as seen in the values in the lowmem package.

Ok, I have now included those changes into my patch, to get the numbers
up-to-date for all archs. 

That is:

amd64:minimum_memory_strict=350
amd64:minimum_memory=780

arm64:minimum_memory_strict=245
arm64:minimum_memory=260

armel:minimum_memory_strict=140
armel:minimum_memory=190

armhf:minimum_memory_strict=140
armhf:minimum_memory=190

i386:minimum_memory_strict=285
i386:minimum_memory=485

mips64el:minimum_memory_strict=200
mips64el:minimum_memory=345

mipsel:minimum_memory_strict=160
mipsel:minimum_memory=170

ppc64el:minimum_memory_strict=256
ppc64el:minimum_memory=500

s390x:minimum_memory_strict=120
s390x:minimum_memory=155

See patch.

> Probably not, as seen in the values in the lowmem package.

I think I found a reasonable solution.

Current situation is:

We have two sorts of numbers for RAM size:

a) some kind of rough values, identical for all archs. These are just 
   subjective values, rounded up to the next bigger RAM modules you can buy
   (current values can be found in
   "Table 3.2. Recommended Minimum System Requirements" at
   https://d-i.debian.org/manual/en.amd64/ch03s04.html )
   These are only rough recommendations, as in "we **recommend** X MB".
   And this chapter 3.4 also mentions, that these recommendations can well be 
   underrun by the second sort of values:
b) these are values based on meassurements during lowmem testing. They are 
   different over the archs, and in the current text they are considered as 
   some kind of strict requirement, as in "you **need** at least X MB" values.
   --> Compare this to the "we **recommend** X MB" values from a) !




Taking all this as a basis, I would like to propose the following:


1. in chapter 2 
(https://people.debian.org/~holgerw/installation-guide___improve-ram-size-values/amd64/ch02s05.html)
   which is about hardware requirements, just mention the minimal rough 
   recommended values from a) which says something like "512MB" or "1GB",
   corresponding to RAM modules available from your favorite hardware store.

2. People who want to try to go with lower values, are guided to
   chapter 3 
(https://people.debian.org/~holgerw/installation-guide___improve-ram-size-values/amd64/ch03s04.html),
   where they find the values from b) based on lowmem tests, which contain
   the "absolute minimum values", drawing the baseline that cannot be underrun.
   Note, that this page is different, depending on arch!

3. Move all the constraints / advanced infos like
 - installer should automatically do memory-saving tricks on low-memory 
systems"
 - warning, when lowmem levels are untested for some archs
 - note, that graphical installer images need more RAM
  from chapter 2 to 3, where they fit better: That's not hardware (which would
  be chapter 2), but how the software deals with the available hardware (so 
  that's chapter 3).

4. I moved the values for "Table 3.2. Recommended Minimum System Requirements"
   from hardcoded values to entities, to ease changings on this in the future
   (especially when looking at translations).

5. I bumped the recommended RAM size values from a) 
   from
   256MB (minimum) + 512MB (recommended)
   to
   512MB (minimum) + 1G (recommended)



All the resulting html files, separated for all archs can be found on
https://people.debian.org/~holgerw/installation-guide___improve-ram-size-values/

The interesting chapters are "Memory and Disk Space Requirements" in chapter 2
and "Meeting Minimum Hardware Requirements" in chapter 3.

You are right.
I could change that into something like 1-2 GB.
One might think, this is still "relatively small" these days, but it's
always enough for the installer, so I think that would be ok.

Ah, I realize that the above is completely bullshit:
the swap partition is not only for the installer, but later for installed 
system as well (shame on me). 

So should I change to "2-4 GB at least" ?

The installer running in low memory mode means that the system RAM is 
less than 1 GB, so I doubt that a swap bigger than 2 GB makes sense.

Now changed to "1-2GB".


Thanks

installer help screen (Was: Re: installation-guide: simplify RAM/disk space requirements)

2023-08-23 Thread Holger Wansing
Hi,

a follow-up on this regarding installer help screen:

Looking at this values (the current ones from lowmem), we have 350MB for
amd64 and 285MB for i386.
The installer help screen F2 has the 285MB value (grabbed from i386 ?) even on 
the amd64 image.

Should this be sync'ed somehow?

(Of course, bumping this value from 285 to 350 means, that the i386 installer
help screen says "350MB needed", which is strictly not correct, but that's 
not a blocker IMO ?)


Or another approach:
should we rephrase this similar to what we have now on
https://d-i.debian.org/manual/en.amd64/ch02s05.html
to say something like 
"We recommend xx MB of RAM" 
instead of 
"You need at least xx"
?

Or even 
"You must have at least 350 megabytes of RAM to use this Debian installer,
but we recommend a minimum of 512 megabytes."

They need to be updated when updating the values in lowmem, yes.

I'd say we can as well just put the amd64 values there.
