WarpDrive is a common user space accelerator framework.  Its main
component
in Kernel is called spimdev, Share Parent IOMMU Mediated Device. It

Not sure whether "share parent IOMMU" is a good term here. better
stick to what capabity you bring to user space, instead of describing
internal trick...

Agree. The "SPI" is also strongly hint to "Share Peripheral Interrupt" or
"Serial
Peripheral Interface". Personally I hate this name. But I cannot find a better
one. In the user space, we can use a impassible name (WarpDrive). But
kernel
require a name point to its feature... maybe I should use "Process-Shared
Mdev"
in next version?

or maybe no new name. Just stick to mdev but introducing some
new attribute/capability to indicate such purpose.

Thanks
Kevin
