This is the third revision of my improvements to the MMC block device error handling, which makes error handling more robust and permits MMC/SD to continue working in the presence of not-quite-perfect setups.
Without this, my Versatile Express tends to fail to mount its rootfs on SD. With this, it can successfully read and write data from the card in the presence of FIFO overruns and underruns, and also sensibly recover from command channel errors. There is more to come, but this is the "safer" bits of the improvements. drivers/mmc/card/block.c | 279 ++++++++++++++++++++++++++++++++++----------- include/linux/mmc/mmc.h | 10 ++ 2 files changed, 221 insertions(+), 68 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
