[mythtv] Ticket #3077: Default CD Device selection

[Nigel Pearson]

> I already did some code to support both:

Nice and small, but it only gets the sysfs model, and not the vendor.
Here is my bloated one:

static void LookupModel(MythMediaDevice* device)
{
     QString   desc;
     QString   devname = device->getDevicePath();
     QFileInfo devpath(devname);


     // Paths like /dev/cdrom usually point to something like /dev/hdc
     if (devpath.isSymLink())
         devname = devpath.readLink();


     // Given something like /dev/sdb1, extract sdb
     devname.mid(5,3);


#ifdef linux
     if (devname.startsWith("hd"))  // IDE drive
     {
         QFile  file("/proc/ide/" + devname + "/model");
         if (file.open(IO_ReadOnly))
         {
             QTextStream stream(&file);

             desc.append(stream.read());
             file.close();
         }
     }

     if (devname.startsWith("sd"))  // SATA/USB/FireWire
     {
         QString path = devname.prepend("/sys/block/");
         path.append("/device/");

         QFile  file(path + "vendor");
         if (file.open(IO_ReadOnly))
         {
             QTextStream stream(&file);

             desc.append(stream.read());
             desc.append(' ');
             file.close();
         }

         file.setName(path + "model");
         if (file.open(IO_ReadOnly))
         {
             QTextStream stream(&file);

             desc.append(stream.read());
             desc.append(' ');
             file.close();
         }
     }
#endif

     device->setDeviceModel(desc);
}

Indeed. Probably morphing molehill into mountain.


I have two at home, but am only using one because
MythTV can't easily distinguish between them.
Annoyingly, they are both Pioneer A108s,
so the vendor/model won't help :(
