Firstly, add a switch to allow/disallow debugfs code to be built
into the CCP driver.
This rest of the patch series implements a set of module parameters
that allow fine-tuned control over which CCPs on a system are enabled
by the driver, and how many queues on each device are activated.
Lastly, a switch to enable/disable DMA engine registration is implemented.
The new parameters are also exposed in DebugFS (when enabled).
Details:
nqueues: configure N queues per CCP (default: 0 - all queues enabled)
maxdev: maximum number of devices to enable (default: 0 - all devices activated)
pcidev: Only consider activating devices with the specified PCI ID (default:
unset - all devices activated)
buses: Only consider activating devices on the specified PCI buses (default:
unset - all devices activated)
dmareg: Register services with the DMA subsystem (default: true)
The maxdev, pcidev and buses parameters aggregate.
Only activated devices will have their DMA services registered.
