If anyone still cares about this, I have done some work on a reverse-engineered driver. Reading and writing to the flash partially works, but as a raw flash device (MTD), not a block device. The device does not have a flash translation layer like an SSD.
The code is available at https://github.com/yarrick/turbomem -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/312380 Title: Support Intel Turbo Memory as a block device Status in The Linux Kernel: New Status in linux package in Ubuntu: Confirmed Bug description: I have a Lenovo T61 (and another Lenovo T61p) that has Intel Turbo Memory in it. I'm not suggesting any approach as to how to use the memory - I just want access to it as a block device so I can do something with it. There is a Brainstorm entry about using Turbo Memory in a fashion similar to ReadyBoost: http://brainstorm.ubuntu.com/idea/12409/ This is *not* what this bug is about - it's just about making the device available for use.
