2016-12-03 18:57:20 < clever> and bcm2710-rpi-3-b.dtb is present
2016-12-03 18:57:32 < viric> it's not about being present
2016-12-03 18:57:35 < viric> it has to match the kernel
2016-12-03 18:57:52 < viric> (I had old dtbs and my machine didn't boot)
2016-12-03 18:57:58 < viric> and yes - they had the same names
2016-12-03 18:57:58 < clever> ah
2016-12-03 18:58:09 < clever> i'm using the dtb from the firmware repo, let me check the kernel build
2016-12-03 18:58:20 < viric> the kernel store path should have them
2016-12-03 18:58:27 < viric> - yes, it's a shame nixos does not copy them. :)
2016-12-03 18:58:41 < viric> I could have saved me enough troubles by adding that 'cp'
2016-12-03 18:58:55 < clever> i thought that the entire point of DT, is that the kernel can take a DT in and configure itself correctly
2016-12-03 18:59:20 < viric> clever: the DTs are per-kernel. DTBs are to make a single kernel binary to boot in different boards
2016-12-03 19:00:10 < viric> what is in the DT and what not varies from version to version of linux
2016-12-03 19:00:36 < Dezgeg> no, DTs are _supposed_ to be independent of the kernel version, it's just that apparently the raspberry people failed to adhere to that
2016-12-03 19:01:17 < viric> aaaah
2016-12-03 19:01:20 < viric> :)
2016-12-03 19:01:43 < viric> let's see if that helps clever
2016-12-03 19:02:09 < Dezgeg> in the mainline world you do get yelled at if you try to break old dtbs (except if you're an important person enough)
2016-12-03 19:02:17 < viric> ok
2016-12-03 19:02:19 < clever> heh
2016-12-03 19:02:30 < viric> I should raise my expectations.
2016-12-03 19:03:18 < clever> i read the source code, and the area that is failing appears to get the GPIO address by asking the firmware over the mailbox
2016-12-03 19:03:24 < clever> which sort of defeats the entire point of DT
2016-12-03 19:03:36 < clever> and shouldnt be capable of failing this badly
