This is a preliminary implementation of the PTM support driver, the code
is obviously hacked together and in need of refactoring. This driver has
only been tested against a virtual PCI bus.
The drivers job is to get to every PTM capable device, set some PCI config
space bits, then go back to sleep .
PTM capable PCIe devices will get a new sysfs entry to allow PTM to be
enabled if automatic PTM activation is disabled, or disabled if so desired.
Comments? Should I explain the PTM registers in more details?
Please CC me, thanks.
