[Ql-Users] QLay Linux
I have had a help request from a user in the Czech Republic asking for help to contact Jan Venema regarding the Linux version of QLay. Does anyone have an up to date email address for him? Please send it to me privately and I’ll forward it on. Alternatively if anyone knows how to help with his query... The email I received was: I have just discovered your site and wanted to discover more about the QL platform. I am a Linux user and I installed qlay emulator, however it appears I am unable to execute it on my system. $ ./QLAY -tJS.rom reports bash: ./QLAY: No such file or directory I have tried contacting the author but his email address no longer exists? Would you know to help. Dilwyn Jones ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Hi, I tried to run SMSQmulator on my 2Ghz, single CPU laptop, under M$Vista. It started up first time and has not crashed, great so far. But I find it VERY slow, much slower than a standard QL, even QPC1 on my i486/25Mhz laptop is faster. It's so slow you can see lines being drawn and paper filling by line of the startup windows, with pauses, despite the 100% processor speed. Well yes, SMSQmulator isn't a hare, but this is excessively slow. I run the Java 7 version. According to my Configuration\Programs list I have both 6 (upd 5) and 7 (Upd 9) on my system. Can that be a problem? No. I used QPC2 to create a QXL.win boot file but when I started SMSQmulator, QPC2 came to a complete standstill. This is probably due to SMSQmulator hogging all the CPU time. So I removed that, and started it again. It ran the boot sequence but that took some 20 minutes (10 secs on QPC2). For brief moments I can see the mouse movement but it goes in slomo after a few seconds and the pointer is then gone for about 10 seconds after each move. Any suggestions? No, not really. What else is running on the machine (antivirus?) It can't be that the puzzle takes only 19 secs to start on a raspberry, but that the boot should take 20 minutes on yours. Spmething is wrong but I fon't know what. How much memory does your computer have?. Normally SMSQmulator shouldn't be more than 10 times slower than QPC...

Re: [Ql-Users] QLay Linux
What the error really means is that the file QLAY (which he is tying to execute) is not in the current directory. Without knowing what the current directory is, how could anyone know if this is an real error or not. Maybe he's in /home/bob and needs to be in /home/bob/qlay? Maybe the case in wrong and it should be Qlay or qlay or something like that. Again, not enough info to do anything with. Kind of like saying my car won't start and then nothing else.

Normal W$ programs don't seem to be slowed down (pdf reader, browser). When QPC2 is running the processor is often at 100%, regardless of what SMSQ is actually doing.

Wolfgang My system has 3MiB of memory and at the time of testing today only Opera was actually running and two Adobe Reader windows are opened for the manuals. Also Task-Manager is started to see the system data (processor 100%, memory at 53%). I have ZoneAlarm (firewall) AVG (anti-virus) active while W$ own Defender is switched off. Also McAfee is present (installed as part of a program update, I forgot which one) but it is not mentioned in the Config/Defence-Centre menu (ZA AVG are). The McAfee panel does not have a switch off option. In new boot tests the startup windows are drawn quite fast, also the resizing as part of my boot goes OK but then the extensions prompts are done letter by letter, about writing speed, with occasionally whole lines at once. ED also fills the window letter by letter and then a few lines at once, very erratic. When the cursor finally arrives it blinks twice and then stops for up to 10 secs.

To boot SMSQmulator on the 256MB Raspberry Pi is something around six minutes. That is also with OpenJDK and not the Oracle Java7 which should run slightly faster*. I still think SMSQmulator is brilliant, especially in the fact that it will run on anything with a Java. * Faster being relative.

Hi John, John j...@sinoda.demon.co.uk wrote: I followed your instructions and overclocked the device to 950 MHz (Turbo caused a black screen but did not seem to damage the file system). It is a corruption that appears intermittently on some Rpis, but not all, when running at 1000 speed. As you got the black screen, you never managed to run at 1000, so you are safe. This changed the boot up time to 4.5 minutes from just over 6 minutes. I make that 25% faster. A bonus! Sadly it is still at 100 CPU all the time. Yes, Java can have this effect even on high end computers. The RPi is very much low spec. Another change you can do, is sudo raspi-config and see what memory split you are using. Giving too much to the GPU can slow down normal less graphical processing. I have mine at 32Mb for the GPU and the rest for the CPU. But I am not sure of the best settings for this emulator. If I run another graphical java app such as gnubridge it uses 100% CPU for about five seconds as it draws to the screen but then the CPU percentage falls to almost nothing. I wonder if the emulator is doing an awful lot of thinking in the background? After all, QDOS was flashing cursors, running interrupt code, flushing slave blocks etc. Equally, I bet there is a huge amount of work being done under the covers by the emulated MC680xx processor.

There is an option to have it take up less CPU time when the cursor is blinking. Even when running 100% CPU, I've found the other applications are not greatly impacted and are fairly responsive.

Re: [Ql-Users] QLay Linux
I just downloaded QLAY and tried it on my Lubuntu 12.4 system. I'm getting the same odd error that the user reported. I made sure that the file was executable, so I did a 'chmod 777 QLAY'. When I did './QLAY', I got the same no sure file or directory. The command 'strace ./QLAY' did not show much. Basically, an execve call was made and it returned ENOENT, which is the same as no such file or directory. There was an llseek system call that returned ESPIPE or Illegal seek. I've never seen Linux or Unix not find a file like that. The file system can see the file. I can chmod the file. I can cat the file. I can rename the file, but trying to execute it, the file can't be found. One suggestion is that the user download the source code and see if he can build it himself. I just tried it and had a number of compiler errors. If the user is not a C person, he may not get it to compile. Has anyone successfully compiled QLAY lately? The source code was last touched in 1999, so it might be a little rusty. Another option is for the user to try the DOS version using DOSBOX on Linux. DOSBOX is great for running old DOS software. I've run stuff that was created in 1986 and it ran fine. Tim Swenson ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
Re: [Ql-Users] SMSQmulator
Hi, I apologise for the confusion. the 19 seconds is to draw the puzzle from pressing 1. To boot SMSQmulator on the 256MB Raspberry Pi is something around six minutes. No you didn't get it wrong, that's exactly what I understood. I just didn't have the figure for the boot time, but inferred that is was less than 20 mins. Still, 6 mins an a pi and 20 mins on a 2 Ghz machine? Strange. That is also with OpenJDK and not the Oracle Java7 which should run slightly faster*. Hmm, they're getting closer and closer, Orcale will soon be based on OpenJDK or vice-versa. Wolfgang ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Regards John Yes but that is normal : SMSQmulator continually loops around interpreting the M68K code of SMSQ/E. It never stops and thus runs flat out all the ftime (play around with the delay when blinking the cursor option, see what that brings).

After all, QDOS was flashing cursors, running interrupt code, flushing slave blocks etc. Equally, I bet there is a huge amount of work being done under the covers by the emulated MC680xx processor. As I said in the earlier message, the emulator is just a continuous loop, always emulating M68K instructions which never stop: Even when idle, Smsq/e always runs (if just to blink the cursor, or just to check that it is not doing anything etc). I have noticed that QPC somehow manages to modulate the CPU time needed when being idle, but I have no idea how that is achieved.

Even when running 100% CPU, I've found the other applications are not greatly impacted and are fairly responsive. I just noticed my fan kick in a lot more often. The Java VM generally only runs on only one core even in a multi core machine - so, when you have a maulti core machine, the other cores are free to do what they want, hence the machien stays responsive.
