SDIO is an interface designed as an extension of the existing + SD card standard, allowing connection of different peripherals + to the host with the standard SD controller. Peripherals + currently sold in the general market include WLAN/BT modules, + cameras, fingerprint readers, and barcode scanners. SDIO is + also used to connect some peripherals in products like + Chromebooks and Wandboard.

+ +

The current main focus of the project is to reimplement the + existing MMC/SD stack using the CAM framework. This will + allow utilizing the well-tested CAM locking model and debug + features.

+ +

The first version of the code was uploaded on Phabricator for + review. The new stack is able to attach to the SD card and + bring it to an operational state. The only supported SD + controller driver is ti_sdhci which is used by the + BeagleBone Black. Modifying other SDHCI-compliant drivers + should not be a hard task.

+ + + + +

At this point, feedback from kernel developers is really + needed. This may be done in the form of code review. If + the chosen way of implementing the CAM-aware MMC stack is + considered correct, then adding code for interacting with SD + cards (for example, setting the optimal transfer rates) will + be the next task.

+ + + +

Write a CAM peripheral driver that implements an interface + to the FreeBSD disk(9). It will send MMC I/O + commands using the MMC XPT layer.

+ + + +

Extending camcontrol(8) to make it possible to + send MMC-specific commands directly to the MMC/SD card using + pass(4) will greatly assist in developing new features for + the stack.

+ + + +

Modify the sdhci(4) driver to work with the new + stack. This is required to work on the new stack using PC + hardware, not only the BeagleBone Black.
