linux.git/drivers/crypto/ccp/ccp-dev.h, branch v4.11 Linux kernel source tree crypto: ccp - Make some CCP DMA channels private 2017-03-24T13:51:34+00:00 Gary R Hook gary.hook@amd.com 2017-03-23T17:53:30+00:00 efc989fce8703914bac091dcc4b8ff7a72ccf987 The CCP registers its queues as channels capable of handling general DMA operations. The NTB driver will use DMA if directed, but as public channels can be reserved for use in asynchronous operations some channels should be held back as private. Since the public/private determination is handled at a device level, reserve the "other" (secondary) CCP channels as private. Add a module parameter that allows for override, to be applied to all channels on all devices.
