I'd been hoping that # everything beyond this was just PCIe hotplug, but it seems not. # Apple's Thunderbolt driver is rather too large to just be handling # ACPI events, and this document on Apple's website makes it pretty # clear that there's OS involvement in events and device configuration. # Booting with a device connected means that the firmware does the # setup, but if you want to support hotplug then the OS needs to know # how to do that - and Linux doesn't. # # Getting this far involved rather a lot of irritation at Apple for # conspiring to do things in a range of non-standard ways, but it turns # out that the real villains of the piece are Intel. The Thunderbolt # controller in the Apples is an Intel part - the 82524EF, according to # Apple. Given Intel's enthusiasm for Linux and their generally high # levels of engagement with the Linux development community, it's # disappointing[1] to discover that this controller has been shipping # for over a year with (a) no Linux driver and (b) no documentation # that would let anyone write such a driver. It's not even mentioned on # Intel's website. So, thanks Intel. You're awful. # # Anyway. This was my attempt to spend a few days doing something more # relaxing than secure boot, and all I ended up with was eczema and # liver pain. Lesson learned, hardware vendors hate you even more than # firmware vendors do. # # [1] By which I mean grotesquely infuriating - -- Christopher Samuel Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: [email protected] Phone: +61 (0)3 903 55545 http://www.vlsci.org.au/ http://twitter.com/vlsci -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlG2caoACgkQO2KABBYQAh8etACdG+gp39WLGPkAMJ6hUvSwpFWI HBQAn0jQcUNf/IGmmbvAbp0MoX8K5esd =MXGS -----END PGP SIGNATURE----- _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
