qemu-m68k's Issues
SONIC interrupt mapping
Most Quadras support an alternative interrupt mapping that is used by A/UX and Linux. It moves the SONIC ethernet IRQ from level 2 (VIA2) to level 3. If you patch Linux to disable this mapping (see patch inhibit-via_alt_mapping.txt), Linux crashes with "unexpected interrupt from 108". This error refers to the level 3 interrupt, since (108 >> 2) - 24 = 3. QEMU raises the level 3 interrupt regardless of via2[vBufB]. In this case, QEMU should raise the NuBus slot 9 interrupt (IRQ 56) instead. I've confirmed this on a Centris 610 (but not a Quadra 800). This bug is no problem for mainline Linux but could be a problem for some other operating systems.
Adding support for /proc/hardware in qemu-user
On linux-m68k, the kernel adds a pseudo file called hardware to the /proc filesystem in order to display some hardware information. Some packages like console-setup use this information to detect the type of m68k hardware being used.
Since console-setup is required for some packages to be built like xorg-server, I have written a very small kernel module which adds the pseudo file containing Model: Atari Falcon (with Afterburner040) which I just copied from the Aranym emulator.
The source code for the kernel module is:
#include <linux/module.h>
#include <linux/proc_fs.h>
#include <linux/seq_file.h>
static int hello_proc_show(struct seq_file *m, void *v) {
seq_printf(m, "Model: Atari Falcon (with Afterburner040)\n");
return 0;
}
static int hello_proc_open(struct inode *inode, struct file *file) {
return single_open(file, hello_proc_show, NULL);
}
static const struct file_operations hello_proc_fops = {
.owner = THIS_MODULE,
.open = hello_proc_open,
.read = seq_read,
.llseek = seq_lseek,
.release = single_release,
};
static int __init hello_proc_init(void) {
proc_create("hardware", 0, NULL, &hello_proc_fops);
return 0;
}
static void __exit hello_proc_exit(void) {
remove_proc_entry("hardware", NULL);
}
MODULE_LICENSE("GPL");
module_init(hello_proc_init);
module_exit(hello_proc_exit);Now, in order to improve compatibility, I was wondering whether it would make sense to add support for the /proc/hardware pseudo file to qemu-user as well? Of course, this would apply to qemu-user on Linux only.
Issues when building some packages with OpenMP enabled
Several packages in Debian like imagemagick or gettext utilize OpenMP to parallize execution and improve performance.
While OpenMP generally works on qemu-m68k (tested with some examples from [1]), qemu-m68k can lock up in user mode when building imagemagick or gettext with the --enable-openmp configure parameter.
For example, the imagemagick build gets stuck when running convert to create some PNG icons from the SVG icons in the source tree [2]:
Make icons for size 8x8... E: Caught signal ‘Terminated’: terminating immediately debian/rules:369: recipe for target 'override_dh_auto_install-arch_iconcache_quantum.q16' failed make[1]: *** [override_dh_auto_install-arch_iconcache_quantum.q16] Terminated debian/rules:189: recipe for target 'binary-arch' failed make: *** [binary-arch] Terminated E: Build killed with signal TERM after 60 minutes of inactivity
This issues goes away immediately when disabling OpenMP support per configure option.
With gettext, the problem occurs in msgmerge which is part of gettext and used when building other packages like apt [3]:
Generating ../build/po/domains/apt/bg.po echo ../build/po/domains/apt/bg.po : bg.po ../build/po/apt.pot > ../build/po/apt_bg.po.d /usr/bin//msgmerge --add-location=file bg.po ../build/po/apt.pot -o ../build/po/domains/apt/bg.po .........make[2]: *** wait: No child processes. Stop. make[2]: *** Waiting for unfinished jobs.... make[2]: *** wait: No child processes. Stop. make[1]: *** wait: No child processes. Stop. make[1]: *** Waiting for unfinished jobs.... make[1]: *** wait: No child processes. Stop. make: *** wait: No child processes. Stop. make: *** Waiting for unfinished jobs.... make: *** wait: No child processes. Stop. Build killed with signal TERM after 30 minutes of inactivity
Again, the problem goes away the moment we build gettext without OpenMP support.
Unfortunately, I have not yet figured out exactly which OpenMP directive is causing the issues since the basic OpenMP examples from [1] don't cause any problems. But I presume it's an issue with when using atomic/critical sections in OpenMP.

Cannot Load -kernel netbsd
qemu-system-m68k cannot load a current NetBSD 7.1 kernel from the -kernel command line option unlike standard qemu for other architectures.
Using qemu-system-m68k version 2.11.90 I get the following error on an unzipped kernel: "Trying to execute code outside RAM or ROM at 0x00002e00"
Regular qemu allows you to boot NetBSD's kernel directly from the command line on other architectures, such as ARM and x86. The kernel is multiboot compliant.
Supporting NetBSD would be really helpful because the system is currently maintained and has a long history 68k Macs. Hopefully this is not out of scope for qemu-m68k.

Can you suggest which?

To reproduce, just install the gedit package and try to run gedit.
FWIW, the problem exists on qemu-sh4 as well. Didn't test with other architectures yet.
cmake 3.11.x lockups qemu-m68k and qemu-sh4
cmake 3.11.x locks up qemu-m68k and qemu-sh4 when trying to build a source code which uses cmake. qemu-arm is not affected by this issue.
The change with cmake that caused this issue is the integration of libuv for asynchronous I/O.
I will provide some strace output later. I'm still in the process of gaining more data.

Long-long register shuffling.
https://gist.github.com/rdebath/67d37e192f88e27d4993e84ab0eb85b0
I'm running:
Branch: 680x0-v2.6.0
Commit: 82c8f6b
The above is a piece of C code using long-longs and compiled without optimisation.
I've compiled it on x86 for the control and two minor variations on m68k.
If I compile it WITH optimisation it runs successfully, if I add in the call to the empty 'f()' function it runs successfully.
If I leave the register shuffling in the unmodified the code it is unsuccessful.
As GCC generates the same code for the two m68k versions (except for the single jsr to the empty function) it would appear that this bug is in the emulator.
Placing the call to 'f()' between any two C statements in this section of the code seems to prevent the problem occurring.

Hi Vivier,
first of all, many thanks for your excellent work in qemu-m68k. I hope that soon your work will become official in the qemu tree.
I'm writing a little "bios" for the m68k, and I was able to start the m68k quadra 800 emulator from
ROM, executing C code and send characters to the serial port. Executing this little fragment (in order to load the msp):
define MBIT (1 << 12)
ori.w #MBIT,%sr // select Master SSP
lea.l msp_stack,%sp // load the stack
andi.w #~MBIT,%sr // select back the ISP
gives me this error:
tcg.c:1981: tcg_reg_alloc_op: Assertion `ts->val_type == 1' failed.
I've tried some changes, but no matter what instructions you put between the ori/andi, the result is the same. Unfortunately I am not confident with the innards of the qemu tcg, so I am kindly filing this issue.
Many thanks again and best regards.

Issues on big-endian hosts
Hi!
I was recently testing qemu-m68k on a sparc64 machine in the hope to work-around the futex issues we have when running on little-endian hosts (because m68k is big-endian, the futex counter is not passed evaluated properly by the kernel), but to my surprise, qemu-m68k actually crashed:

Report the selected CPU in the bootinfo for the m68k machine + add a way to pass 68000, 68010 via boot info?
Hi,
I used your virt machine with 68000 selected to revive the linux 68000 support.
I have a port of u-boot that runs on the 68000 too and creates a device tree from the bootinfo.
The sticking point I have right now is to make my 68000 enabled kernel boot on any 68k I need to patch some interrupt handling stuff to handle the vector/frame type field missing.
If the virt machine could report the select cpu via the bootinfo (it's always 68040 right now) I could flip which cpu is used and test my code works. But it seems like bootinfo doesn't actually have flags for 68000 or 68010 so I'm not sure what we would do there.
Thanks!

I was copy pasting about 1k of text into terminal to Linux operating over serial console (didn't setup ssh server and port mapping yet), and well, kernel said this:
[ 269.280000] ttyPZ0: pmz: rx irq flood !
after this, the terminal / serial console is not usable.
At least I can't sand anything again.
I guess it would make sense to throttle rx irqs on serial lines to be in some sane range? Try to emulate some baudrate limits that the driver expects to be sane too?

Password for firebird 3.0
-------------------------
Firebird has a special user named SYSDBA, which is the user that has access to all databases. SYSDBA can also create new databases and users. Because of this, it is
necessary to secure SYSDBA with a password.
The password is stored in /etc/firebird/3.0/SYSDBA.password (readable only by root). You may modify it there (don't forget to update the security database too, using the
gsec utility), or you may use dpkg-reconfigure to update both.
If you don't enter a password, a random one will be used (and stored in SYSDBA.password).
Password for SYSDBA:

Missing libraries for static build of m68k-linux-user
Following the how-to at https://wiki.debian.org/M68k/sbuildQEMU I was not able to buildqemu-68k, it misses functions from librdmacm and libibverbs.a. The libraries were installed but not the headers? Missing in build-dep? apt-rdepends --build-depends qemu | grep rdmacm says it is in build-dep.
But the problem persisted even after installing librdmacm-dev, a make distclean and a ./configure --target-list=m68k-linux-user --static --disable-glusterfs .
A quick solution for me was to add /PATH/TO/librdmacm.a /PATH/TO/libibverbs.a to the variable COMMON_LDADDS in m68k-linux-user/Makefile.
WRT: execve flag
Commit 8952fce8 "linux-user: add option to intercept execve() syscalls" adds the ability to specify that only this copy of the QEMU executable will be used for execve.
It has some issues:
- It doesn't pass on the option to exec'd programs.
- If you just set the environment variable (and use binfmt misc) it fails with a very weird error.
- It can't run SUID executables.
I'm using this patch to work around some of this buy simply putting the path to the exe in the variable, however, it's not complete as I have to turn it off for SUID executables.
There are several ways this could be worked (all the way up to fakeroot/fakechroot support) but as I have solved my immediate problem (Which was to prevent x86 static executables running) it seemed best to just report this.

and it seems that the macro in the new version is QEMU_IFLA_NUM_RX_QUEUES with QEMU prefix,I'm not sure how to change that.
The branch q800-v1.1.0 seems no problem ,but when I use the qemu-system-m68k to lauch the kernel build in lxc ,it comes with segmentation fault when lauch /sbin/init and use other command.Can you tell me how to fix these issue

#aptitude crashes with 'qemu:handle_cpu_signal received signal outside vCPU context'
Recent changes have introduced a regression when running aptitude on qemu-m68k, crashing with:
qemu:handle_cpu_signal received signal outside vCPU context @ pc=0x6019a64f
qemu:handle_cpu_signal received signal outside vCPU context @ pc=0x601b393b
See https://buildd.debian.org/status/fetch.php?pkg=elinks&arch=m68k&ver=0.13%7E20190125-1&stamp=1549095796&raw=0 for a sample build log.
I initially thought this to be a regression in qemu because the problem just showed up recently but it also shows with older qemu versions which used to work fine in the past, so I assume something changed in aptitude which is now causing the problem.
Reproducer is simple after installing aptitude:

Unimplemented fmove from control 7 when running uic from qt5
With git 5e79823 from master-dev, trying to build razorqt in an up-to-date unstable m68k chroot, the build fails when trying to run qt5's user-interface compiler (uic):
cd /<>/obj-m68k-linux-gnu/razorqt-panel/plugin-cpuload && /usr/lib/m68k-linux-gnu/qt4/bin/uic -o /<>/obj-m68k-linux-gnu/razorqt-panel/plugin-cpuload/ui_razorcpuloadconfiguration.h /<>/razorqt-panel/plugin-cpuload/razorcpuloadconfiguration.ui

Attaching the build log.
The underlying issue has been discussed in a previous private discussion with Michael Karcher:

Can I have the instruction opcode ?Valid control register values are only 1, 2, 4, so I assume this
instruction is not decoded correctly.
It seems that it actually is a bit mask, and 7 means "all of them". Have
a look at the gdb output:(sid-m68k-sbuild)/tmp/qt4-x11-4.8.7+dfsg/src/gui# gdb ../../bin/uic qemu_uic_20151212-154524_27519.core

Again, you're right

Screen does not update properly when playing 'Prince of Persia' in 256 color on qemu-m68k
When playing Prince of Persia in 256-color on qemu-m68k (-M q800) graphics only update when player character moves across screen. Clicking the mouse or moving the curser will also update regions of the screen. Note: This does not occur with b/w mode and I tried Increasing memory in 256-color but the issue did not improve.
Rare random parse errors when building Haskell code
This is another issue which will be hard to track down. The fix from 843cd25 already brought lots of improvement, so that many Haskell packages build now fine. But there are still some occasional hickups [1]:
[ 6 of 27] Compiling UU.Pretty ( src/UU/Pretty.hs, dist-ghc/build/UU/Pretty.o )

make: *** [build-ghc-stamp] Error 1
dpkg-buildpackage: error: debian/rules build-arch gave error exit status 2
The problem with this one is that it's not easily reproducible but it does occur. As already mentioned in #20, maybe we need to add the fix from e9f4459 for the other CAS instructions as well?

qemu-m68k/tcg/tcg.c:1774: tcg fatal error (temp_load():TEMP_VAL_DEAD:abort())
When tried to look at GHC to m68k (https://ghc.haskell.org/trac/ghc/ticket/11395)
I've got to a state where qemu-m68k fails to execute C-compiled code
with an internal error. Here is the selfcontained example that can crash qemu:
# m68k.S:
# build as:
# m68k-unknown-linux-gnu-gcc -nostdlib -nostartfiles m68k.S -o foo
# run as:
# qemu-m68k -d unimp,guest_errors,in_asm -L /usr/m68k-unknown-linux-gnu/ foo
#
# fails as:
# IN:

# 0x80000058: rts
# qemu-m68k/tcg/tcg.c:1774: tcg fatal error
_start:
asll #2,%d0
movel %a0@-,%d2
rts
AFAIU this should not cause qemu fail to translate.
(for completeness) The real-world crash trace looks like that:

-m 1000M works. -m 1024M doesn't.
-m 1015M works. -m 1016M doesn't.
I guess it is either not supported completly due to architecture limitations, or some memory is mapped incorrectly.
One option is to fix it, another (if it is arch issue), to refuse to start if the memory requrested is too big, or something.
-m 1281M refuses to start:

-m 1280M does start but crashes.
However, with -m 1200M, it does work:

Guest memory corrupted by incoming network packets
QEMU symptoms look like "DOUBLE MMU FAULT" or a SIGABORT.
I'm fairly sure that the same bug sometimes shows up as a Linux kernel Oops in skb_release_data. It can also show up as a non-responsive network interface, followed by a crash.
qemu-crash-macsonic-skb_release_data.log
To reproduce these symptoms requires heavy network traffic. Ping flooding can do it.
One way to reproduce the crash is with a few of these, after the network goes silent:
echo macsonic > /sys/bus/platform/drivers/macsonic/unbind
echo macsonic > /sys/bus/platform/drivers/macsonic/bind
echo macsonic > /sys/bus/platform/drivers/macsonic/unbind
echo macsonic > /sys/bus/platform/drivers/macsonic/bind
I found and fixed some bugs in the macsonic driver (see my github repo) but it didn't make a lot of difference.

The recent revision of the m68k-dev has introduced a regression with GHC:

Serial console no longer works with Quadra 800 emulation
I'm currently writing a small guide on how to install and set up Debian/m68k on qemu-system-m68k from the q800-dev branch but I'm having trouble to get a working serial console.
I have an older git snapshot installation where the serial console works fine but now the kernel messages stop once the kernel tries to initialize ttyS0.
Link to the the current guide I created on the Debian wiki: https://wiki.debian.org/M68k/QemuSystemM68k
FPU issues when installing inkscape package
When trying to install inkscape, we're running into an issue which seems FPU-related:

btyacc on qemu-m68k misbehaves if compiled with -O2
So, this is a rather obfuscated and weird bug, but there is definitely something wrong in qemu-m68k.
The package firebird2.5 (after applying the platform support patch in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=828141#10) currently fails to build from source on qemu-m68k but not on Aranym due to btyacc - which is embedded in the firebird2.5 sources - generating incorrect output. However, this happens only when compiling btyacc with "-O2". Compiling it without optimization does not trigger this problem.
Furthermore, the separate btyacc package in Debian - which was compiled a long time ago with an older version of gcc - does not show that behavior on qemu-m68k. The problem is triggered only when compiling btyacc with gcc-4.9 or newer (although we didn't test 4.7 or 4.8, but the working binary was compiled with a rather old gcc version, around gcc-4 or so). It does not matter whether btyacc is compiled on Aranym or qemu-m68k, but only whether -O2 is used or not. The -O2-built binary will always work correctly on Aranym and always misbehave on qemu-m68k.
Here is a detailed demonstration of the issue:
On Aranym:
