An MMC/SD/SDIO stack using CAM Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's flexible queueing will make it easier to write non-storage drivers than the legacy stack. SDIO drivers from both the kernel and as userland daemons are possible, though much of that functionality will come later. Some of the CAM integration isn't complete (there are sleeps in the device probe state machine, for example), but those minor issues can be improved in-tree more easily than out of tree and shouldn't gate progress on other fronts. Appologies to reviews if specific items have been overlooked. Submitted by: Ilya Bakulin Reviewed by: emaste, imp, mav, adrian, ian Differential Review: https://reviews.freebsd.org/D4761 merge with first commit, various compile hacks.

An MMC/SD/SDIO stack using CAM Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's flexible queueing will make it easier to write non-storage drivers than the legacy stack. SDIO drivers from both the kernel and as userland daemons are possible, though much of that functionality will come later. Some of the CAM integration isn't complete (there are sleeps in the device probe state machine, for example), but those minor issues can be improved in-tree more easily than out of tree and shouldn't gate progress on other fronts. Appologies to reviews if specific items have been overlooked.
