| i want to import the drom for thunderbolt 1 devices? https://gist.github.com/joevt/4f6d4d97b560efab9603ac509bf00122 |
| linux and osx when using cb/tianocore is not detecting the ports property. in osx when i use retail bios i see 2 ports but with tianocore its 4. also the uid is the default 0x100000 instead of the acutal uid from the drom. then in linux the /sys/bus/thunderbolt/devices/0-0/device_name etc is missing. its suppose to read from drom in spi rom and put it somewhere in kmem |
| the dmesg in retail shows |
