A more actively-developed framework is LightNVM for Open-Channel SSDs. The kernel bits have been upstreamed into mainline kernel as well: http://lightnvm.io/ http://lightnvm.io/ I met the project architects at a conference earlier this year, and they are on the right track IMO. If only more vendors would support the notion of open-channel SSDs which allow for custom FTLs from outside the device. Also, per the LightNVM supported hardware list: "Other platform such as OpenSSD Jasmine and OpenSSD Cosmos are able to support LightNVM. However, there are no compatible firmwares yet."
