Started some more work on display_adapter, but I just get stuck on new style driver writing. The idea was that every display_adapter will have an adapter device, and that adapter will then register displays attached. (It may or may not be the best way to do this, but atm that is what I am doing, so bear with me.) This is what happens: The display adapters are found, and running: KERN: DBUG_support: scanning at bus: acpi path: \_SB_.PCI0.GFX0 KERN: displayadapter_support: found at bus: aKERN: cpi path: \_SB_.PCI0.GFX0 KERN: publish device: node 0x8281d7d0, path display_adapter/0, module drivers/display_adapter/display_adapter/device_v1 It then scans displays: KERN: Display ID = 1024 KERN: name: DD01 KERN: Child _adr 256 KERN: name: LCDD KERN: Child _adr 1024 KERN: publish device: node 0x82bb5338, path display_adapter/0/LCDD, module drivers/display_adapter/display_adapter/display/device_v1 However, display_init is never called and no errors in syslog. So can anyone tell me what I should do different? It's a new-style driver. The code is here: http://cgit.haiku-os.org/haiku/tree/src/add-ons/kernel/drivers/display Code of interest is display_adapter::register_displays and display.cpp Please help save my sanity :) /Fredrik Holmqvist, TQH
