unit code for new faster bitblt
by tim Rowledge 30 Jul '13

30 Jul '13

Hi Ian, Here at last is a dump of the unix related files that provide the faster bitblt for the Pi and any other interested platform. Although a lot of the work was specialised for ARM machines there is a fair bit that is completely generic and should (I emphasize the 'should') work on any machine since it is plain C code. There is another chunk that is about to go into Cross, which seems the best place at least to start us off. Hopefully the attached zip will transfer correctly, though given how tediously annoying it was to assemble I would be surprised. The xarchive tool provided in Raspbian is, to be polite, pathetic. I eventually gave up and used the zip tool in Squeak; it may be best to use that to extract the files since I noticed that at least on my iMac the existence of two files named config.cmake caused problems. What we have here is - vm/sqPlatformSpecific.h with a #define added - this is clearly not a really good solution and if you know how to make it practical to cause cmake to allow configure with or without -DENABLE_FAST_BLT whilst not messing up the assorted CFLAGS I'd be very pleased. - plugins/BitBltPlugin/config.cmake a new file in a new directory. This *seems* to work correctly on non-ARM machines but I am unable to guarantee it is the right way to do things. I didn't write it, so feel free to excoriate it. - vm-display-x11/ config.cmake (see previous) sqUnixX11Arm.s - assembler code for a faster routine for converting the pixel format sqUnixX11.c - modified old file to use above faster display handler. I added archive comments to the file to hopefully help sort out which config is which. If I can send you the files in some more convenient manner just let me know. The value of this on the Pi is pretty high, with some cases being 10x faster; I'll be interested to know if it does any good on other machines. Someone may find it interesting to do the x86 assembler as an experiment, though I'd be surprised if it made as much difference on a fast large memory bus as on a slow narrow one. cc'd to the rest of the gang in case anyone wants to play with it right now. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: ESBD: Erase System and Burn Documentation

[Cog] primitiveLoadImageSegment fails
by Bert Freudenberg 20 Jul '13

20 Jul '13

That's primitive 99. With an updated Squeak trunk image I can load this project fine in the interpreter: http://etoys.squeak.org/svn/trunk/Etoys/Home.007.pr On Cog the primitive fails. Any idea what might be wrong? - Bert -

"The tragedy of PIC" summary
by stephane ducasse 02 Jul '13

02 Jul '13

Hi eliot So I was reading the PhD of Holzle and I wanted to know - I remember that at southampton (yes that far) you did a presentation on the tragedy of the PIC. And I would not find the slides (because there were none). What was the pitch? That megamorphic site are killing PIC? - does VW use type feedback? if yes, what were the strategies to decide what and when to recompile. - I was wondering how type feedback and PIC interact (I'm at chapter 5 of the PhD so may be this is explain in the self implementation part) the first case of the PIC could be based on type feedback?

Can't infer base LD_LIBRARY_PATH on a Debian box
by Frank Shearar 29 Jun '13

29 Jun '13

Can't infer base LD_LIBRARY_PATH. Aborting. Try adding a line for /lib/i386-linux-gnu/i686/cmov/libc.so.6 (0xb753d000) to /home/tonyg/jenkins/workspace/ExternalPackages-Metacello/target/cog.r2732/coglinux/bin/squeak. Please report your edit to squeak vm-dev. This comes from Tony Garnock-Jones' lfpdeb32 box, which I presume is a 3-bit Debian box of some vintage. frank

making a unix release package
by tim Rowledge 29 Jun '13

29 Jun '13

Now that I can actually make Pi VMs with or without the fast blt at will, I'd like to be able to assemble a package that I can send out to a few people for testing. I feel sure there used to be a makefile target to do this but can't spot anything that appears appropriate in the current setup. So how does one do it these days? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim I do not fear computers. I fear the lack of them.

Raspberry Pi colocation as a near-free Seaside server
by tim Rowledge 29 Jun '13

29 Jun '13

Consider http://raspberrycolocation.com/home/ (or perhaps these guys -http://www.edis.at/en/server/colocation/austria/raspberrypi/ and I see plausible looking others around the net ) and then think of setting up an SD card with your website running on Seaside. Raspbian can already run the StackVM and in the not too distant future should have a Cog system. Ought to run Seaside fairly well I'd imagine. Like they say, life's a beach... tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Any Sufficiently Advanced Incompetence Is Indistinguishable From Malice
