Wubble : High Speed SD/MMC kernel for Diablo 5.2008.43

High Speed SD/MMC kernel for Diablo 5.2008.43

I’m rather behind the times, but I’ve now released a matching kernel for Diablo 5.2008.43 with the highspeed SD/MMC support. Make sure to update to 5.2008.43 before installing my kernel or the update will overwrite it.

You can find my custom kernel, patches and instructions here.

thanks, works great!
can you make kernel with the mmc patch and the rotation support?

Hi Philip, please consider adding also bugfix for RNDIS https://bugs.maemo.org/show_bug.cgi?id=3243 and consitent mmc device names https://bugs.maemo.org/show_bug.cgi?id=2747 so people don’t need to chose between buggy kernel with faster mmc or fixed one. Thanks. BTW, it would be nice to solve ‘random’ mmc device names upstream too.

Any concrete benchmarks before I go and ruin my device?

balihb, fanoush: I don’t really have to time to handle integration of other patches – I publish my kernels as a small attempt to be helpful, but I think it really needs someone with more time available to handle pulling in multiple patches and making sure they work together.

Wellu: Under ideal conditions, it should make your cards transfer data twice as fast – in practice it won’t be quite that, but the difference should be noticeable. There are some numbers in my past posts.

I flashed this kernel, but I don’t notice any improvement. How do I check the bus speed?

I see 48000000Hz in the dmesg output:
mmc1: clock 48000000Hz busmode 2 powermode 2 cs 0 Vdd 7 width 2 time 2
