Visopsys 0.85 Released

Hello all, As always, I've still got a few more things to finish for 0.9, but in the meantime here's a roll-up of all the things I've back-ported to the 0.8x branch. From the changelog: Overview: This maintenance release adds RAM disk boot support, RAM disk backing for temporary files in read-only m...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

Sorry for the delay. The patches ended up being quite large, mostly because I'm fussy about my code, and ended up rearranging and reformatting a bunch of (mostly older) stuff. Here's your first link. This is just a debug USB image with my latest code - just in case I've already solved the problem. T...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

Yes, I am ready to test the new images. Wish you a Happy New Year ! :) Happy new year to you as well. OK cool, I'm just integrating a few patches (all improvements related to this investigation). I hope to finish that tonight or tomorrow night, and then I'll post one or more images for you to try. ...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

Yes, I could debug it using a USB. Will be waiting patiently for your USB debug image ;) So after disabling all the PCI interrupts by default: Apparently, yes, on this machine my IDE controller is actually going wild with interrupts, and the OHCI and XHCI USB controllers are doing a few unexpected ...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

Update: still working on this, but it's a MOFO tricky one. It's like legitimate devices are interrupting legitimately, but the interrupt service routines (ISRs) of several PCI drivers (IDE, different USB ones) aren't recognizing them, and then complaining about missed interrupts. Very weird, doesn'...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

Yeah, looks like something's not quite right with the APIC driver on this machine. There's some device that keeps firing unserviced interrupts and it's messing everything up. It's a complicated thing though, so I'll need a bit of time just to re-read the docs and get my mind back in that zone. Unle...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

Thought I'd stop by and see if you'd released another version. I must have had a clairvoyant connection - since you've just mentioned in the previous post that you're about ready to do it. Any networking in the next version uptick or is that still targeted for the dot nine release? With your being ...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

My own dev workstation can't boot Visopsys. It looks like the problem is also interrupt-related. Maybe the same cause? I've been procrastinating debugging it because it's awkward to test on the same machine you normally use for compiling :-) Anyway, maybe I should focus on this one here, and give y...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

Yes, I could debug it using a USB. Will be waiting patiently for your USB debug image ;) Apologies for the delay - I've been pushing (in my small amount of free time) to get everything finished for 0.85 and 0.9. I think I'll do the 0.85 release in the next few days. My own dev workstation can't boo...

Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

link Sadly it can't boot to Visopsys as a virtual floppy ( have you also applied your workaround from https://visopsys.org/forums/viewtopic.php?f=3&t=338#p1594 ? ). A bit later I'm going to try USB. Just in case, here's a new log - with a "Controller has no interrupt" message Detecting hardware: SA...
