Re: scupt-tc real hardware: 0/3
I now have found the genode/contrib/nova... directory, and was able to
pinpoint the problem to:
void init (mword mbi)
{
// Setup 0-page and 1-page
memset (reinterpret_cast(_0), 0, PAGE_SIZE);
memset (reinterpret_cast(_1), ~0u, PAGE_SIZE);
for (void (**func)() = _G; func != _E; (*func++)()) ;
---^
that line
while(1) before hang the computer, while(1) after have the computer reboot.
I have a feeling few years ago I had found that this was like the 3th or
4th index...
But I have like kind no clue how to find the associated code
(constructor code).

I would suggest to instrument NOVA and see up to which point it gets.
Well, because I had no VGA output at all, I thought that bender was not working.
I removed it from GRUB config, and start with the kernel.
This does not help.
I also try the different parameters to Nova, but without change.
(The most obvious one was removing IOMMU).
The bring-up of the other CPUs/Hyperthread seem to be missing in your
log output. ([ 0] CORE:0:0:0 6:f:b:0 ).
You are misled, this is not mine outout.
I don't have serial output (I 'stupidly' throw away my serial null cable).
I followed your suggestion to update BIOS.
BIOS gone from 2006 version to late 2011 one.
Now dmidecode does way much more nice information! (was having just about 5
short hexadecimal tables before).
But that did not help.
I am not too sure how to keep a version of the Nova kernel to work on.
I searched for the source, but it does not seems to be kept in after the
prepare... which leave the
the compiled .o and compiled hypervisor in the bin? directory of the build
directory.
That said, I got a look at the code on
https://github.com/udosteinberg/NOVA/tree/master/src
And it looks way too familiar.
In fact, I think I had isolated similar if not exact same symptom when I work
on that few years? ago.
When I look in init.cpp code:
extern "C" INIT REGPARM (1)
void init (mword mbi)
{
// Setup 0-page and 1-page
memset (reinterpret_cast(_0), 0, PAGE_SIZE);
memset (reinterpret_cast(_1), ~0u, PAGE_SIZE);
for (void (**func)() = _G; func != _E; (*func++)()) ;
Hip::build (mbi);
for (void (**func)() = _C; func != _G; (*func++)()) ;
// Now we're ready to talk to the world
Console::print ("\fNOVA Microhypervisor v%d-%07lx (%s): %s %s [%s]\n", CFG_VER,
reinterpret_cast(_VER), ARCH, __DATE__, __TIME__, COMPILER_STRING);
I can like remember that I was blocking in these constructors code calling
functions loops (more the
second one from memory). I believe I was back then using the same technique I
was to use here:
adding while (1) line to see when it hangs and when it reboots.
I can see they are coming from hypervisor.ld file:
.init_array : AT (ADDR (.init_array) - OFFSET)
{
PROVIDE (CTORS_L = .);
KEEP (SORT_BY_INIT_PRIORITY(*)(.init_array.65534 .ctors.1))
PROVIDE (CTORS_C = .);
KEEP (SORT_BY_INIT_PRIORITY(*)(.init_array.65533 .ctors.2))
PROVIDE (CTORS_G = .);
KEEP (SORT_BY_INIT_PRIORITY(*)(.init_array.* .ctors.*))
KEEP (*(.init_array .ctors))
PROVIDE (CTORS_E = .);
} : kern
but that's looking like black magic to me.
I suspect this is a way to do what a C++ runtime would do to call static class
constructors... but
this is mostly a guess from the .ctors name.
Anyway, back then I believe the code was not taken from git hub at prepare
time, then erased after prepare.
And now, I am unsure if I must write patches in the patch directory or what.
I really wish I would have the Nova source kept, and that make would recompile
Nova on demand but I have pretty
much no clue how to achieve that.

So, AMD machines may work to some degree, but it is not expected to work well. Regarding SATA/AHCI and AMD, in Sculpt TC the driver manager only considers Intel AHCI chips [0], so your SATA disks can't work since no driver is started at all. It would be great, if AMD users out there test/debug our AHCI driver with some simpler scenario and open up feature issues on github, so that it be added for the next releases. I'm afraid I've communicated poorly here. I was just playing around with it, and was surprised it worked as well as it did on an unsupported system. If/when adding AMD support becomes a priority, I'll be happy to help with testing, etc. Until then, I'm happy with what we already have. Actually, I'm planning on getting a refurbished ThinkPad soon, so I should be able to join the supported hardware club! With some luck, I will try to use Genode as my "daily driver", since I already run everything in VirtualBox VMs. ___ Genode users mailing list users@lists.genode.org https://lists.genode.org/listinfo/users
Re: scupt-tc real hardware: 0/3
Anyway, I fixed it the wild way:
~/genode/repos/libports/src/drivers/framebuffer/vesa/main.cc
protected:
Session_component *_create_session(char const *args)
override
{
// unsigned scr_width =
_session_arg("width", args, "fb_width", 0);
// unsigned scr_height =
_session_arg("height", args, "fb_height", 0);
unsigned scr_width = 1280;
unsigned scr_height = 1024;
unsigned const scr_depth =
_session_arg("depth", args, "fb_mode", 16);
And now run/framebuffer run on my real computer with my real monitor...
not the probably infinitely width and height monitor in QEMU! :)

Re: scupt-tc real hardware: 0/3
I am confused because the VGA framebuffer says that it's default configuration is 1024x768.

Re: scupt-tc real hardware: 0/3
I think I finally come to a real Genode problem (rather than a platform one): On X86_64, I ran: make KERNEL=foc run/framebuffer and running on my Dell Optiplex 745, with integrated i965 I got: Error: acpi table out of range - 0xfff69ab8 not in [ , 3fff ) See how it finished with ) rather than the expected ] More seriously, who put a limit on where my acpi table can be?

Re: scupt-tc real hardware: 0/3
I think I tried all platforms for x86... and the last one is the one that works on my Optiplex 745 is: Fiasco.OC (foc). I ran: make KERNEL=foc run/bomb on X86_32 Now, hopefully I will be able to come back to 64 bits, and especially, try something less frightening than bomb! :) ___ Genode users mailing list users@lists.genode.org https://lists.genode.org/listinfo/users

Like I said, I haven't tried virtualization yet, but it booted from the USB stick, saw the external USB drive, connected using wired networking, and installed packages from the internet. It didn't like my ThinkPad keyboard with built-in TrackPoint, but neither do the BIOS setup screens. ___ Genode users mailing list users@lists.genode.org https://lists.genode.org/listinfo/users

I would guess it would not work on a DVD?). I have downloaded it yesterday, and tried it on 3 computers (2 almost the same: Dell Optiplex 745, not sure the other is a 745 too). One of the two is my own computer, and I have try many BIOS config, but it does always do the same: show the Logo, screen become black for about 7 secs... then it reboots and loop. Hi Paul, Welcome back ;-) I noticed the same boot loop on a Dell Optiplex 380. This one is so old it has a serial and parallel port. The serial port showed me some boot lines and if I remember correctly it was something about missing video card before the reboot. If someone wants, I can capture that serial log and hardware specs. I'm not sure if the GMA 4500 video chip is supported by Genode, if you have an old VESA video card lying around, you might have some more luck on the Dell. I ran Sculpt on a 6 year old Sandy Bridge Pentium (G620) with built-in video chip, that runs great, after some trouble with network and usb. Genode likes my Intel gbit Nic better than the RTL 8111/8169. I got some spurios hangs on the latter. It also booted on my AMD Ryzen 5 system but it did not detect SATA drives. Nor did virtualisation work. Both Vbox and Seoul hang. Better than I expected but not usable yet. Hope this encourages you to keep going on with Genode :-) Cheers, Guido. ___ Genode users mailing list users@lists.genode.org https://lists.genode.org/listinfo/users
