I did not believe that Hercules and TK4- would work well on a Raspberry Pi 4.? Being a RP4 rookie, I found a website that gave easy direction to downloaded and install Hercules and TK4-.? Sure enough - it worked.? It seemed to me to be as responsive as on my desktop winblows 10 box.? My first challenge is to change the sign on panel to read "My Raspberry Pi Thinks Its a Mainframe".

Works well on a pi zero too! Air 2

"well" is relative. Doing a sysgen from scratch on a zero was a multiday process that never completed; I finally did the gen on an Intel system, and moved my DASD over to the PI. It was ok. As I recall, getting the SMP volumes prepared was the really slow part; it's possible that once you had a starter volume and the SMP volume with everything ACCEPTED, doing a sysgen on a Zero would be possible...

Hi Ed,
Can you share with us the link you found with clear instructions?? I am reluctant to buy a Pi until I know there are reliable instructions to follow!
Also, what is the "best" website to order a Pi 4 or latest model?
Thanks,
ScottC?

Hello! I can answer that one, try the ones at I find that site, and those stores to be in most regards, perfect. Although I am leaning towards the two I use here in New York. Although the Pi3 I have here and sometimes use was delivered as part of some sort of participation via Element14. ----- Gregg C Levine gregg.drwho8@...

Hi Scott
The URL you asked for is:
Since this is my first one, I bought my rp4b complete 32GB kit from Amazon.? I have dealt with Microcenter in the past and they seem good as well.

Choosing the proper compile options make a huge difference, especially for the PI4, I daresay.?
Kind regards

Michael,
And what exactly would "the proper compile options" be, for an RPi4??

Oh excuse me, this has been already posted earlier I supposed. Here is what I used:
./configure --enable-optimization="-O3 -frename-registers -mhard-float -pipe -mlittle-endian -munaligned-access -march=armv8-a+crc+simd -mcpu=cortex-a72 -mtune=cortex-a72 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard" --prefix=/home/pi/herc42/linux/arm --enable-extpkgs=/home/pi/sources/extpkgs

Of course, the absolute paths in this simple example must be adjusted to the individual environment. Given the circumstances,? I’ve just did a simple copy and paste.?

Hi Scott, given the lack of reliability of SD cards when dealing with lots of IO activity/filesystem writes, I’d recommend the use of an USB 3.0 attached disk to you. Even though a PI4 cannot completely boot from USB without the help of a boot image on SD, I think it is worth it. I use 512GB SSD ?disks“ on both of my PI4. A beta of a new firmware that may have your PI4 boot directly from an USB 3.0 device is available, but I did not want to toast my PI so I’m waiting until it is safe to upgrade. In the meantime, a redirect of the root partition in the /boot/config.txt helps.
Kind regards

Michael,
Thank you, sir.? (I must have missed that earlier post.)

Has anyone done a full sysgen on one of these?? I am referring to following Jay Mosley’s instructions.
Assuming that you follow the Hercules install and compile instructions.?? I’d assume it takes longer than on a much faster Desktop Linux machine – but is it possible and has it been done successfully?
?
Thanks,
Dave

Hi Mark,

I tried it on a Pi Zero; I ended up giving up. **too** slow, couldn't tell if it was stuck or just slow.
The slow part was getting the SMP volumes built. I think if you followed Jay's instructions to the point where you had your starter system and SMP volumes built, you could move over to a Pi and be ok (and once you have those, you never need to build them again)...
You may have a fighting chance on a Pi 3 or 4.
One thing that was killing me was that I had compressed DASD, which was ****really**** slow on a Pi Zero when doing a lot of writes.

See /g/H390-MVS/message/209
|
So then, forgive me if this is obvious, I could take a fully generated and configured MVS system, shut it down – tar up the MVS directory like I do for a backup – move that tar file to a Pi – extract the tar file – and then boot using Hercules
on the pi, and it would work the same (not discussing speed)?
?
If SO, that’s cool.

Thanks,
Dave
