I still get ASan warning but it's about gpio_i2c_init in bitbang_i2c.c
which I haven't changed nor using so I think this is pre-existing problem
in bitbang_i2c.c which was exposed by touching it now so I'm not trying to
fix. (Maybe adding an exit function to free the allocated bitbang_i2c in
object state could help but I think it still leaks the bus so I'm not sure
how to handle it correctly. Maybe this should be QOMified somehow but
cannot be a device because it's not connected to a bus but embedded in
other device models.)

It can inherit from I2CBus and then specific devices could inherit from
the bitbang interface. That's almost certainly the right way to do this,
but that design issue isn't cause by your changes.
I'll try to poke at this a bit to see if I can clean it up.

That's almost certainly the right way to do this, It's OK for a QOMified bitbang_i2c to inherit from I2CBus but I don't think other devices can inherit from it. I'm using it from devices that are PCI (ati-vga) or SysBus devices (ppc4xx_i2c but also the gpio_i2c) but happen to have an i2c component so they can't inherit from bitbang_i2c only refer to an instance of it. > but that design issue isn't cause by your changes. > > I'll try to poke at this a bit to see if I can clean it up. I wonder if we really need a QOM object for this or if it would be enough to provide a bitbang_i2c_free function that dereferences the I2CBus which we can call to finalise a bitbang_i2c created with bitbang_i2c_init?

That would probably work. If this is going to be used on x86, then a QOM object is required to allow migration. Outside of that, I think it's more correct form in qemu, but not required. -corey > > Regards, > BALATON Zoltan
