+ + + MMC Stack Under CAM Framework + + + + + Ilya + Bakulin + + kibab@FreeBSD.org + + + + + Project Information + Source Code + + + +

The goal of this project is to reimplement the existing + MMC/SD stack using the CAM framework. This will permit + utilizing the well-tested CAM locking model and debugging + features. It will also be possible to process interrupts + generated by the inserted card, which is a prerequisite for + implementing the SDIO interface. SDIO support is necessary + for communicating with the WiFi/BT modules found on many + development boards, like Raspberry Pi 3.

+ +

Another feature that the new stack will have is support for + sending SD commands from userland applications using + cam(3). This will allow for building device drivers in + userland and make debugging much easier.

+ +

The new stack is able to attach to the SD card and bring it + to an operational state so that it is possible to read and + write to the card.

+ +

The stack has been tested to work on the Beaglebone Black and + Wandboard Quad platforms.

+ +

Currently the code is being prepared for inclusion in the + &os; source tree. cam(3) is being extended to + support SDIO-specific functions (reading registers, managing + interrupts).

+ + + + Integrate the code into &os; HEAD to facilitate + testing. + + Begin writing driver for Broadcom-based WLAN chips (found + on the Raspberry Pi 3 and Wandboard). + + Begin writing driver for Marvell-based WLAN chips (found + on the GlobalScale Dreamplug and some Chromebooks). + +
