       @mntmn as much as I despise that protocol: can that monitor do DisplayLink?

       Current mood is "I keep wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my free day with moping about how I'm wasting my …"

       @lritter lol.1. Tierschutzpartei2. Volt3. die PARTEIDie Linken wären weiter oben, wenn sie nicht so undogmatische Realos wären, die energieintensive Unternehmen subventionieren wollen.

       @mntmn @bluerise shouldn't the device tree be supplied to the kernel by the bootloader?

       @mntmn one idea I have floating in my head is an A1200 turbo card that fits in the original case, and also feeds power (so it can be used in tower conversion kits)

       @mntmn I have an A1200 with BlizzardPPC and BVisionPPC — but the cooling is inadequate, it's loud and with 128 MB RAM the lid doesn't close anymore — and the second module doesn't even fit, so clearly something has to be done.

       @q66 @mntmn @manawyrm main problem seems to be that the root bridge does not forward VGA accesses, and the xe driver not only assumes it does, but also that it is routed to the right device.Other than that, multiple PCI domains are a way cleaner way to communicate "we do not support device-to-device transfers" than a hardcoded list of PCI IDs that do.

       @mntmn yes, also hyperventilation doesn't help and it takes really long to recover. Half an hour later I'm at least back at 100/85, but I still don't want to move.

       @mntmn change the report format and make it the kernel's problem? :>

       @mntmn UEFI has a protocol for passing device trees, it should be possible to build a bootloader that does not require a DTB argument.

       @mntmn the I2C isolators are expensive because they need to deal with all the annoying things permitted in the protocol, like clock stretching, and they can be damaged too. Better than the CPU, but still annoying.The cheapest option is probably a small resistor in line with the signal pins, like 33 ohms, or a set of TVS diodes.The combination of both is likely to be a bit wonky, because the TVS diodes have some leakage, and if you add a resistor, driving the bus through that resistor against the leakage currents is going to raise your zeros and lower your ones -- but if you can find a combination that keeps the signal in a valid range assuming the worst in manufacturing tolerance, that will be the best protection.The other thing that makes sense is to design the connector so that GND connects first (GND on the outsides and with longer pins if possible), that way the signal lines should be in range when they connect, and the capacitance of the I2C lines should be low enough on the battery board that connecting the GND does not damage the controller.

       So many things to work on, all at the same time.

       @sylvia_ritter the living artists have a tendency to object to the accumulation of obscene amounts of wealth.

       @mntmn yeah, alas the FMA implementations in the tensor coprocessors aren't useful for that because they only support weird 16 bit floats as inputs.

       @mntmn Time to play an hour of Hollow Knight and/or take a long walk.The QCS6490 goes last, because it is likely the longest task, and the one where you don't want the others looming over your head anymore.PCBs will take a few days to arrive once they are done. The test farm will probably take hours before it shows a result, and probably needs more handholding in that time, so "PCBs first" sounds like a good plan.Also, the test farm setup can probably be delegated.
