    Usb audio uses isochronous transfers, are you sure that qemu usb redirection supports it?

    @zukow
    I don't know how to answer your question. I don't have the preparation to do it,
    but the author told me it could be a usb1.1 problem since i use usb 2.0 3.0 ports,

    I followed some advice from the author of qemu-ppc for -sam460ex -g4 -pegasos2
    the author does not have a usb-audio stick at the moment to do my own tests.

    where the principle to follow should be this:

    complete control over the USB-audio stick by the host to passthrough the device.

    and also on usbhid the hardest part

    with this I take full control of the usb-audio:
    UDEV
    ACTION == "add", SUBSYSTEM == "usb", ATTR {idVendor} == "0d8c", ATTR {idProduct} == "0014", OWNER = "white"
    ATTRS {idVendor} == "0d8c", ATTRS {idProduct} == "0014", ENV {PULSE_IGNORE} = "1", OWNER = "white"

    BLACKLIST
    blacklist snd_usb_audio
    blacklist snd_usb_midi_lib

    the hardest part is usbhid where in reality I can't find any solution to prevent it from talking to usb-audio.

    a solution looked like this:

    for device in $(ls /sys/bus/usb/devices/*/product); do echo $device;cat $device;done

    USB Audio Device
    /sys/bus/usb/devices/1-6/product

    sudo dmesg

    the driver is disassociated

    but in the end it is useless because in this way as soon as I reinsert the usb-audio stick the usbhid regains control of it.

    i can add the log i get as soon as i remove the qemu usb-audio only the initial lines in this case else it is much longer ..
    I have no idea what they are I guess Morphos is not finding something or that he is taking action while I remove the USB-audio

    in summary these are the principles that the author recommended to me.

    but this .log I don't know if it can be useful for the purpose that I have not yet sent to the author.

    I just have to create a UDEV rule for usbhid
    I believe it can be done

    if that is the purpose.

    Thanks for any help :-)

    I am not aware of qemu being able to emulate any cards that MorphOS has drivers for.

    ok :-)
    I give up

    using an "asus" motherboard I was convinced that I had identified the usbhid :-)

    going to see the individual components

    with:
    sudo lsusb -vvd 0b05: 1899

    it actually corresponds to the keyboard
    Bus 005 Device 003: ID 0b05: 1899 ASUSTek Computer, Inc. TUF GAMING K5
    Device Descriptor:
    bLength 18
    bDescriptorType 1
    bcdUSB 1.10
    bDeviceClass 0
    bDeviceSubClass 0
    bDeviceProtocol 0
    bMaxPacketSize0 64
    idVendor 0x0b05 ASUSTek Computer, Inc.
    idProduct 0x1899
    bcdDevice 0.45
    iManufacturer 1 ASUSTeK
    iProduct 2 TUF GAMING K5

    etc. etc.

    therefore completely wrong road.

    I remain of the idea that if the developer does not personally try a usb-audio stick to see how it works.

    Of course I personally can't do anything about it.

    I will dedicate myself to something else :-)

    it remains only that with qemu sam460ex the usb-audio stick is perfectly recognized in all its parts only problem is that you can't hear the sound.

    I would work on this, but it's not up to me.

    Well it was a nice pastime I learned other things. :-)

    I have a doubt, How I can send lha/lzx files from Windows host to QEMU running MorphOS, because I can download files via Internet, but is there other way?
    Thanks.

    @Templario
    Hi,
    Honestly not if it is possible to do it I do not use qemu to do many things.
    I guess you can mount real partitions but I've never tried.

    a simple way is to use a usb data stick like this with qemu:

    -usb -device usb-host,vendorid=0xeba4,productid=0x7588

    I don't use qemu with windows
    "usb deview" for windows should give you the right IDs

    download link usbdeview x64

    this is a quick solution move your files to the stick and then mount it with qemu.

    I am not aware of qemu being able to emulate any cards that MorphOS has drivers for.


    SB128 driver (https://github.com/aros-development-team/AROS/tree/master/workbench/devs/AHI/Drivers/SB128) sort of works with some problems (maybe driver bugs) with AROS PPC on Qemu PPC after some changes/hacks to QEMU's hw/audio/es1370.c. Port to MOS would probably take half an hour.

    QEMU hw/audio/es1370.c/es_write():

    Code:

    + val = bswap32(val); /* maybe the AHI driver is supposed to do that */
      addr = es1370_fixup (s, addr);


    QEMU hw/audio/es1370.c/es_read():

    Code:

    + val = bswap32(val); /* maybe the AHI driver is supposed to do that */
      return val;


    QEMU hw/audio/es1370.c/es_transfer_audio():

    Code:

    + if (1) { /* surely the AHI driver is supposed to do that */
    +   unsigned short sample;
    +   int ii;
    +  
    +   for(ii = 0; ii < to_copy / 2; ii++)
    +   {
    +    sample = ((unsigned short *)tmpbuf)[ii];
    +    ((unsigned short *)tmpbuf)[ii] = bswap16(sample);
    +   }
    + }

      copied = AUD_write (voice, tmpbuf, to_copy);


    It does not really work correctly but it makes the beep sound in AHI Prefs program when clicking Test button. But there are sometimes distortions. Sometimes it sounds correct. Maybe something with buffer underflow, interrupt problem. Don't know. Qemu x86 with AROS x86 with same SB128 driver has same sound problem.

    Normally when running AROS on qemu on Linux with PulseAudio, sound is muted with this driver. A workaround for AROS is to also activate the ac97 drive in qemu, not just the es1370 device. The ac97 AHI driver I guess does something in initialization that causes the sound to no longer be muted:

    Code:

    qemu-system-ppc .. .. -device ac97,audiodev=snd0 -device es1370,audiodev=snd0 -audiodev pa,id=snd0


    Another workaround is to build and run qemu-system-ppc with alsa driver (is by default notcompiled in). But sound distortions are worse compared to PulseAudio.

    Code:

    ./configure --target-list="ppc-softmmu" --audio-drv-list=pa,alsa

    ..

    qemu-system-ppc -audiodev alsa,id=snd0

    The AC97 driver (https://github.com/aros-development-team/AROS/tree/master/workbench/devs/AHI/Drivers/ac97) works too and works better than SB128 after similiar endianess hacks to QEMU's ac97.c:

    hw/audio/ac97.c/fetch_bd():

    Code:

    +#if 0
         r->bd.addr = le32_to_cpu (*(uint32_t *) &b[0]) & ~3;
         r->bd.ctl_len = le32_to_cpu (*(uint32_t *) &b[4]);
    +#else
    +    r->bd.addr = be32_to_cpu (*(uint32_t *) &b[0]) & ~3;
    +    r->bd.ctl_len = be32_to_cpu (*(uint32_t *) &b[4]);
    +#endif


    hw/audio/ac97.c/ac_97_io_nam_ops struct:

    Code:

    -    .endianness = DEVICE_LITTE_ENDIAN,
    +    .endianness = DEVICE_BIG_ENDIAN,


    hw/audio/ac97.c/ac97_io_nabm_ops struct:

    Code:

    -    .endianness = DEVICE_LITTE_ENDIAN,
    +    .endianness = DEVICE_BIG_ENDIAN,


    hw/audio/ac97.c/write_audio() before AUD_write() call:

    Code:

    {
      unsigned short sample;
      int ii;
      
      for(ii = 0; ii < to_copy / 2; ii++)
      {
         sample = ((unsigned short *)tmpbuf)[ii];
         ((unsigned short *)tmpbuf)[ii] = bswap16(sample);
      }
    }


    Code:

    ./qemu-system-ppc -machine sam460ex -rtc base=localtime   -drive if=none,id=cd,file=aros-sam440-ppc.iso,format=raw -device ide-cd,drive=cd,bus=ide.1 -device ac97,audiodev=snd0 -audiodev pa,id=snd0

    Is QEmu a viable solution compared to a real Powerbook or Powermac? Can you drive multiple monitors?

    No and no.
