Devicetree. Ugh.
On one project I attempted to move the kernel from 3.0.35 to 3.10 and even that was a huge pile of problems, asking vendors to bring their drivers up to speed. Some did, some didn't. It wasn't worth the trouble so off we went, shipping with 3.0.35.
- digi_owl 11y agoWell i think it is the closest ARM has to PCI enumeration right now. Best i recall, Intel started Moblin (that later merged with Maemo to from Meego) because their mobile Atom SoC didn't provide PCI enumeration. Thus MS was reluctant to provide a Windows version for it, as Windows was highly reliant on just that for hardware management.
- david-given 11y agoDidn't Open Firmware solve all these problems years ago? I'm pretty sure I remember operating systems being able to use Open Firmware to query option ROMs for driver details in a scalable (and machine independent!) way, way back in the 1990s. It's always saddened me that Open Firmware never got picked up for IA. They went for EFI instead...
- digi_owl 11y agoBest i can tell, devicetree originated with Open Firmware.
