Hi This is version 2 of my Thunderbolt driver for Apple hardware (see [1] for v1). The short story is that Apple decided to implement hotplug support in a driver instead of the firmware. The firmware will only initialize coldplugged devices. Hotplugged devices do not work. This series adds support for single device hotplug (no chaining) for the Cactus Ridge C4 Thunderbolt controller (device id 0x1547, present on MacBookPro10,1). As far as I can tell newer generations work quite similar and it should be possible to add support for more controllers with some work. Changes from v1: - suspend/hibernate support (yeah) - general cleanups and refactoring >From my perspective the driver is working quite well and is ready for merging (maybe someone can tell me whom I should ask to get a review?). I have taken some care to not stomp on tunnels setup by the firmware for coldplugged devices. If this works as intendend then there should be no regressions (coldplugged devices continue to work and simple hotplugged devices will start working). In particular the Apple Ethernet adapter works very well (and this is probably the most used TB device out there). Some notes: - The patch requires Matthew's acpi_osi fix [2] - @pci, Bjorn: I hope patch 12 is acceptable. If there is a better way to do this please let me know. - Thunderbolt displays: I have a pretty good idea on how they should work, but I did not yet write any code to support them. Also judging by the replies I got for v1 of the patch it seems that there are some graphics driver problems even with coldplugged tb displays (at least on MBP models with discrete graphics cards). - Hibernate gotcha: The amount of available memory reported by the firmware depends on whether a tb device is connected. This makes Linux refuse to restore the saved image. This has nothing to do with this driver, but you might run into it during testing.
