(0x0ce5e000) Thanks In the title, you talk about PPC, but in the bug description, you talk about i386 ... quite confusing, please try to be consistent. But since you say that you run into this problem with all machine types, this sounds like a configuration problem to me. Can you please specify how you run the configure script and what output you get there? Also, did you do a "make install" or are you trying to run QEMU from the folder where you compiled it? What output do you get if you run qemu-system-ppc64 with "-nographic" option? Hi T, yes it is the emulated i386 machine qemu-system-i386 and it was working since something change in 2.6. but issue is present in ppc machine too. dint try the kvm because on ppcemb there is not vga output. I had try the 2.5.1 and build and work and confirmed the issue is present only in 2.6 ususally i build it with this : ./configure --with-sdlabi=2.0 --audio-drv-list=pa,sdl --target-list=i386-softmmu,ppc-softmmu,ppc64-softmmu i had been try with sdlabi=1.2 and without audio and without target list but have the same issue. after work i will write my configure output probably can help? Luigi Ah, you mean your *host* is running Ubuntu 16.10 PPC (i.e. not your guest)? Only looking at the title of this bug, I was assuming you were talking about the guest running Ubuntu 16.10 PPC (i.e. the host could also be a x86 machine)... So yes, please provide also the output of "./configure ..." and specify the exact command line parameter that you use to run the emulator. Hi tony this are my configurations command i use for run the qemu-system-i386 note it is working on 2.5.1 and 2.6 old release attached a shot you can see all is working in previous versions of 2.6 Aros: qemu-system-i386 -m 2047 -drive file=/mnt/c7a1331a-6bfe-436e-b43d-fe2afead48e9/Aros.img,id=disk0,format=raw -net nic,model=rtl8139 -net user,smb=/home/amigaone/shared/ -vga vmware -balloon none -display sdl -cpu athlon -mem-prealloc -device virtio-scsi-pci,id=scsi -soundhw es1370 -cdrom /home/amigaone/emulators.iso Win98: qemu-system-i386 -m 256 -drive file=/media/amigaone/mame/vhd/win98.img,id=disk0,format=raw -vga cirrus -display sdl -balloon none -mem-prealloc -device virtio-scsi-pci,id=scsi -rtc clock=host,base=localtime -serial none -parallel none winXP: qemu-system-i386 -m 2047 -drive file=/media/amigaone/mame/vhd/xp_black,id=disk0,format=raw -net nic,model=rtl8139 -net user,smb=/home/amigaone/shared/ -vga virtio -balloon virtio -display sdl -cpu athlon -mem-prealloc but qemu is working if only i open it thru qemu-system-i386 ... i have default setting with 128mb and bios running ... with lastest git not only "Guest has not initialized the display yet " or quitting like i described before...

I think this issue is present on all ppc world Can you use "git bisect" to determine the exact commit that causes this problem to appear? Hi T, i can gave a try ... i never used "git bisect" i have to use it with the executable? with "git bisect log" or somthing else? You initially have to specify a commit that is known to fail, and one that is known to work, so in this case it's likely: git bisect start master v2.6.0 It then checks out a revision inbetween. Compile it with "make" and run the built QEMU to check whether it is working or not. If it is not working, use this command to continue: git bisect bad If it was working, use this command instead: git bisect good Then continue to compile and test the next revision. git bisect should guide you this way to the commit that introduced the bug. Hi T, thanks for the infos i will report ASAP Hi T, found! this was last bad a select git bisect bad Bisecting: 101 revisions left to test after this (roughly 7 steps) [f68419eee9a966f5a915314c43cda6778f976a77] Merge remote-tracking branch 'remotes/kevin/tags/for-upstream' into staging this is the good git bisect good Bisecting: 58 revisions left to test after this (roughly 6 steps) [14fccfa91ecac7af36ac03dc1c2bb9a1d7fbca26] Merge remote-tracking branch 'remotes/lalrae/tags/mips-20160513' into staging Ciao Luigi but what i see in this working there isnt your sdl2 patch. If git bisect says something about "XX revisions left to test after this" then you're not done yet, you have to continue the git bisecting process until it is finished. And if you need the sdl2 patch additionally, you have to apply it manually after each step if necessary. I'm sorry, it's quite cumbersome, but likely still the best solution to determine where your problem comes from. Hi T, Ok. I m sorry i was thinking only this was needed i will made the other git bisect and report Luigi Hi t, this is what you need? 70f87e0f0aa04f764dabaeb3ed71ff195748076a is the first bad commit Hi t, just to notice the 2.7 is effected too :-( ./qemu-system-i386 qemu-system-i386: Trying to execute code outside RAM or ROM at 0x000a0000 This usually means one of the following happened: (1) You told QEMU to execute a kernel for the wrong machine type, and it crashed on startup (eg trying to run a raspberry pi kernel on a versatilepb QEMU machine) (2) You didn't give QEMU a kernel or BIOS filename at all, and QEMU executed a ROM full of no-op instructions until it fell off the end (3) Your guest kernel has a bug and crashed by jumping off into nowhere This is almost always one of the first two, so check your command line and that you are using the right type of kernel for this machine.

It means all the emulated machine not work , virtualized only run. in my case on g5 quad i cant emulate an X86 or a old world mac but i can virtualize my g5 quad with a debian. same is on p5020 machine. Hope it help Hi Luigi, 70f87e0f0aa04f764dabaeb3ed71ff195748076a is a merge commit ... that should not have shown up as a result from bisecting. Anyway, since it is pointing to a ui merge ... could you please: 1) check whether it is still working fine with the first patch of that ui series, i.e.: git checkout 4fd811a6bd0b8f24f4761fc281454494c336d310 and then compile and test that version 2) check whether it is really hanging / not working withe the last patch of that ui series, i.e.: git checkout 6978dc4adcdf27722aa6f9e13f88a903b30a3f8d and then compile and test that version Thanks! Hi T, bad news i had to format my partition with 16.10 and dont have the 2.6.0 src any more if there is a way to git clone it please letme know. note : 2.6.1 have the issue , 2.7.x is effected too. Luigi Alll revisions are available in the git repository, so please simply do: git clone git://git.qemu-project.org/qemu.git cd qemu git checkout 4fd811a6bd0b8f24f4761fc281454494c336d310 ./configure ... make -j4 And then check whether it is working or not. Once you're done, switch to the other revision and compile again: git checkout 6978dc4adcdf27722aa6f9e13f88a903b30a3f8d make -j4 and check whether that one is working or not. Hi T, good news the 2.6.2 is working without the issue reported, but it not include your previous patches . Ciao Luigi
