That said I would prefer to introduce the machine first and then populate with devices. May be it is time to introduce a new machine file. This one seems like it could go in a f35.c file, also because a larger f35-* is in plan. aspeed.c could contain the basic definitions and helpers. > --- > hw/arm/aspeed.c | 48 ++++++++++++++++++++++++++++++++++++++++++++++++ > 1 file changed, 48 insertions(+) > > diff --git a/hw/arm/aspeed.c b/hw/arm/aspeed.c > index a06f7c1b62..75971ef2ca 100644 > --- a/hw/arm/aspeed.c > +++ b/hw/arm/aspeed.c > @@ -1429,6 +1429,50 @@ static void aspeed_minibmc_machine_ast1030_evb_class_init(ObjectClass *oc, > amc->macs_mask = 0; > } > > +static void oby35_cl_i2c_init(AspeedMachineState *bmc) > +{ > + AspeedSoCState *soc = &bmc->soc; > + I2CBus *i2c[14]; > + I2CBus *ssd[8]; > + int i; > + > + for (i = 0; i < 14; i++) { > + i2c[i] = aspeed_i2c_get_bus(&soc->i2c, i); > + } > + get_pca9548_channels(i2c[1], 0x71, ssd); We should rename to aspeed_get_pca9548_channels > + > + i2c_slave_create_simple(i2c[0], "fby35-sb-cpld", 0x21); > + i2c_slave_create_simple(i2c[1], "tmp105", 0x48); > + i2c_slave_create_simple(i2c[1], "tmp105", 0x49); > + i2c_slave_create_simple(i2c[1], "tmp105", 0x4a); > + i2c_slave_create_simple(i2c[1], "adm1272", 0x40); > + i2c_slave_create_simple(i2c[1], "tmp421", 0x4c); > + i2c_slave_create_simple(i2c[2], "intel-me", 0x16); > + i2c_slave_create_simple(i2c[4], "isl69259", 0x76); > + i2c_slave_create_simple(i2c[4], "isl69259", 0x62); > + i2c_slave_create_simple(i2c[4], "isl69259", 0x60); > + > + for (int i = 0; i < 8; i++) { > + i2c_slave_create_simple(ssd[i], "tmp105", 0x6a); > + } > + > + /* > + * FIXME: This should actually be the BMC, but both the ME and the BMC QEMU has an embedded IPMI BMC simulator. > + * are IPMB endpoints, and the current ME implementation is generic > + * enough to respond normally to some things. > + */ > + i2c_slave_create_simple(i2c[6], "intel-me", 0x10); > +} > + > +static void aspeed_machine_oby35_cl_class_init(ObjectClass *oc, void *data) > +{ > + MachineClass *mc = MACHINE_CLASS(oc); > + AspeedMachineClass *amc = ASPEED_MACHINE_CLASS(oc); > + > + mc->desc = "Meta Platforms fby35 CraterLake BIC (Cortex-M4)"; > + amc->i2c_init = oby35_cl_i2c_init; > +} > + > static const TypeInfo aspeed_machine_types[] = { > { > .name = MACHINE_TYPE_NAME("palmetto-bmc"), > @@ -1494,6 +1538,10 @@ static const TypeInfo aspeed_machine_types[] = { > .name = MACHINE_TYPE_NAME("ast1030-evb"), > .parent = TYPE_ASPEED_MACHINE, > .class_init = aspeed_minibmc_machine_ast1030_evb_class_init, > + }, { > + .name = MACHINE_TYPE_NAME("oby35-cl"), > + .parent = MACHINE_TYPE_NAME("ast1030-evb"), hmm, so we are inheriting from the evb ?

Yes, patrick@stwcx.xyz was thinking the same thing. An f35.c (well, maybe yv35.c or fby35.c would be more appropriate) would be a good idea.

Yeah, I remember this was controversial with fby35-bmc too, maybe I'll change this in the follow-up. I just like inheriting from the EVB's because people use the EVB's a lot for testing, most of the time I'm just trying to add some extra i2c devices/etc, so I override the i2c init. But, maybe it's good to decouple them. > > C. > > > > + .class_init = aspeed_machine_oby35_cl_class_init, > > }, { > > .name = TYPE_ASPEED_MACHINE, > > .parent = TYPE_MACHINE, >

Yeah I'm going to resubmit these three separately and cc Titus, and I'm also going to move the IC_DEVICE_ID to a class property like you suggested. I'm just wondering if I'll need to add an ISLClass, since right now it's just a simple type using PMBusDeviceClass, but perhaps if we switch to a class property it would be acceptable to add the implementation of the IC_DEVICE_ID read command to the generic pmbus device implementation, instead of only implementing it for the VR's?

BICs and multi SoC system are new. Oh shoot, I just remembered, the oby35-cl machine won't work without the VR patches. I know the pull request you just made didn't include it, just a reminder.
