I managed to update my Kingston eMMCs with a slighly modified patch to what I submitted. I however didn't bother to submit this, as I saw no chance of getting it applied. Also I once asked in the mailing list if there is some user-space example of how to use the multi-block feature that is supposed to enable this, but I haven't gotten an answer. > Regarding mmc-utils as where I recommend you to implement this, I have > been thinking of moving this tool into the tools directory in the > kernel. Sounds good to me. Remotely related: Do you know that some google people made their own version of mmc-utils for ChromeOS? And the don't seem to give much effort in unification of them? As if the world wouldn't know how hard it can be to re-unite things again, Google should know from their custom kernels they use on Android ... Sigh. So you can * git clone git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc-utils.git * git clone https://chromium.googlesource.com/chromiumos/third_party/mmc-utils currently.
