Hi folks,
The attached patch changes OFMEM so that instead of allocating new space
within the Forth dictionary every time the /memory and /virtual-memory
available/translations nodes are updated, we simply change the property
to point directly to a static buffer. This has the effect of saving
substantial amounts of memory during OpenSolaris 10 boot (in fact the
final dictionary size after boot is now < 256K once again).
Blue/Andreas: please could you take a look at this patch and make sure
it doesn't break anything in your SPARC64/PPC tests?
On the plus side, with this patch applied Milax gets to the end of its
natural boot without crashing giving the following output:

mk48t59 is a newer version of mk48t08, there is alarm etc.

Actually, while mc146818rtc is linked in, it's not used (there are
some machines that have similar device, so that's why it still hangs
around). m48t59 is on ebus.
Maybe it's time to pick a specific real machine type instead of 'Sun4u
platform'. Something that is not too far from what we have now, with
PC-like hardware. Is Netra-T1 OK?

Have you meanwhile tried to change the name to "mk48t59" ? I think
changing the chip in qemu is not neccessary (and even if it is the
name in OpenBIOS has to be changed anyway).

If Blue's subsequent comment about it already being wired up to the ebus
is correct, then yes, probably renaming might work if the device
registers are mapped correctly. Alas this was the last time I touched
SPARC64 before switching to SPARC32, and so I never really looked into this.

Yes, Blue is right (and I've managed to correct my wrong statement one

the device is connected via ebus.

New subject: [PATCH] RFC: Change ofmem_common.c to set memory translation properties by reference
Mark,
Am 14.10.2010 um 22:32 schrieb Mark Cave-Ayland:
The attached patch changes OFMEM so that instead of
allocating new
space within the Forth dictionary every time the /memory and /
virtual-memory available/translations nodes are updated, we simply
change the property to point directly to a static buffer. This has
the effect of saving substantial amounts of memory during
OpenSolaris 10 boot (in fact the final dictionary size after boot is
now < 256K once again).
Blue/Andreas: please could you take a look at this patch and make
sure it doesn't break anything in your SPARC64/PPC tests?
It looks as if none of us actually tested or ack'ed it yet, all
answers were about sparc progress and devices only...
Me for one couldn't save your inline patch and my mailer is known to
cause whitespace damage, and git-am wasn't able to handle the mbox
file since your SVN diff is missing the a/ directory level expected by
Git.
If you're asking for comments from us, please be more patient. I'm
still playing with Blue's slightly older libgcc patch, and some
trivial ones of mine (e.g., CONFIG_RTAS or wrong return) are awaiting
review/committing longer than yours. Please at least let us know in
advance how long you're gonna wait, so that we have a chance to send
in incomplete review comments even if still untested.
I like the general optimization idea, but I found one typo s/fix/fit/
and I was wondering whether the property setting function really needs
to live inside ofmem_common.c or whether we might want to make
set_property_nocopy() out of it for general use.
I also had some style questions related to the inconsistent use of
spacing inside braces. Some ppc code even has a wild mix of tabs and 8
spaces, which is unfortunate when many other projects including QEMU
use an indentation of 4. We're lacking a CODING_STYLE document imo, to
look up which way it's supposed to be.

Andreas
P.S. I have local patches to prepare ofmem_release() inside
ofmem_common.c.

I'd vote for QEMU style because of common developer base and even

I feel your pain when it comes to having multiple patchsets on the go at

various things that had bugs, which when I fixed had other other bugs...
In terms of the patch comments, maybe I could have waited longer.
Generally the OpenBIOS code is still being actively developed, and so
the few people actively working on the code generally push on with what
they are doing, and as long as people don't introduce regressions then
no-one complains too loudly.
A few times when I've been unsure about a patch, I've posted it to the
list for comment and people have been fairly quick in the past to
criticise any bad points, so mostly I accept lack of response that
people are generally happy with it. Perhaps now with more people working
on the code we should reconsider this? I also did a complete set of
testing on my PPC test images and didn't see any regressions there, so I
felt it was reasonably safe...

please could you take a look at this patch and make sure
it doesn't break anything in your SPARC64/PPC tests?
It looks as if none of us actually tested or ack'ed it yet, all answers
were about sparc progress and devices only...
Me for one couldn't save your inline patch and my mailer is known to
cause whitespace damage, and git-am wasn't able to handle the mbox file
since your SVN diff is missing the a/ directory level expected by Git.
If you're asking for comments from us, please be more patient. I'm still
playing with Blue's slightly older libgcc patch, and some trivial ones
of mine (e.g., CONFIG_RTAS or wrong return) are awaiting
review/committing longer than yours. Please at least let us know in
advance how long you're gonna wait, so that we have a chance to send in
incomplete review comments even if still untested. I like the general optimization idea, but I found one
typo s/fix/fit/
and I was wondering whether the property setting function really needs
to live inside ofmem_common.c or whether we might want to make
set_property_nocopy() out of it for general use.
Yes possibly, although I think strings/integers need to be encoded (and
it is the encoding process that makes the copy of the input) whereas
natively the properties work using byte arrays and so we can just set
the property to point directly to them.
I also had some style questions related to the
inconsistent use of
spacing inside braces. Some ppc code even has a wild mix of tabs and 8
spaces, which is unfortunate when many other projects including QEMU use
an indentation of 4. We're lacking a CODING_STYLE document imo, to look
up which way it's supposed to be.
Yes, maybe we should start thinking more about CODING_STYLE...
BR,
Andreas
P.S. I have local patches to prepare ofmem_release() inside ofmem_common.c.
Interesting - these would be very useful :)
ATB,
Mark.
