This is an unsupported update of the original driver source for FusionIO cards. It comes with no warranty, it may cause DATA LOSS or CORRUPTION. Therefore it is NOT meant for production use, just for testing purposes.
Driver support for FusionIO cards has been lagging behind kernel releases, effectively making these cards an expensive paperweight when running a distribution like Ubuntu / Arch / Fedora / ProxMox which all supply newer kernels than supported.
Releases are tagged, and should be checked out by their tag. The release tags follow Linux Kernel versions. E.g. v5.6.0 (MEGACHONKER) will work on all 5.x kernels that are 5.6 and lower, but is not guaranteed to work on 5.7. v4.20.0 - Grey Dawn supports most kernels that pre-date 5.0.
| Tag | Codename |
|---|---|
| v5.6.0 | MEGACHONKER |
| v4.20.0 | Grey Dawn |
The driver is derived from the original iomemory-vsl-3.2.16, but has several fixes and gone through rigorous cleaning of redundant unused and old code. Active development is done on master, while tags are used for releases. The new releases are all tagged from master, whereas the v4.20 releases are tagged from fio-3.2.16.1732.
The modified source fixes several known bugs in the driver:
- silent IO drops
- crashes during driver unload
- SCSI queue settings
- BIO status handling
Commits to master are not "always" write tested, just compile tested. Releases have gone through testing with Flexible I/O Tester. Testing for page_cache errors, and generic FIO checksumming on read and write and different block sizes.

Installation can be done with created packages, DKMS or other options described in the original README.
Dynamic Kernel Module Support automates away the requirement of having to repackage the kernel module with every kernel and headers update that takes place on the system.

Installing the fio-util, fio-common, fio-preinstall and fio-sysvinit are recommended. When moving from source 2.3.11 to source 3.2.10 the firmware HAS TO BE UPDATED to 3.2.10.20150212. For the move to 3.2.15, and 3.2.16 from 3.2.10 I've not seen any issues with my card.
