Fanoush, does the 52mhz mmc kernel also contain the mppe patch?

Thanks,

Yes and no

crypto code is in but pptp is in extra module.

Mini-SD speed?
 

Hi

It's mentioned elsewhere about a new Nokia tablet, 870/880 in the works, and talks about mini-SD in the spec. If true, does Fanoush, anyone know if mini-SD offers the same performance as mmc?

I also think mini-SD is closed source so presumably speed tweaks might be harder? Though maybe mini-SD is already runs at a high speed.

Cheers

as for features there is nice table here
http://en.wikipedia.org/wiki/SD_card

I am not sure SD or miniSD is best choice for future. It may be more widespread right now but the limits (both speed and size) are lower then MMCplus. SD is dead end and will be replaced by incompatible SDHC soon http://www.sdcard.org/sdhc/index.html

Still miniSD is improvement over current mmc slot in N770.

As for being open, SD is worse but not much, I hope the time when SD card kernel drivers were closed source (sharp zaurus) is over. We will see soon :-)

I still don't understand why they did not chose full SD slot which is the best solution for consumers (cheapest cards, better interoperability) but being phone company miniSD was probably more logical and maybe a bit cheaper to them.

diffs against nov 2006 2.6.16 kernel
 

fanosh,

Can I get you to post your diffs for the kernel source - particularly those against the just released 2.6.16-27-omap1? I'm interested to see how your patches in drivers/mmc/*.c and includes/linux/mmc/*.h square with mine. Thanks,

-dacb

I have used this patch for high-speed mode
http://marc.theaimsgroup.com/?l=linu...18628389&q=raw
but replaced 'mmc_set_data_timeout(&data, card, 0);' call by older code from 2.6.16

as for omap and n770 specific parts I just bumped frequency to 48Mhz both in drivers/mmc/omap.c and arch/arm/mach-omap1/board-nokia770-mmc.c

I will produce diff eventually, but I don't have both old and new source trees right now.

OK, it looks like we are both back porting from patches applied to 2.6.18 - fwiw, I understand that the the high speed (sans omap-1 specific hardcodes) and the multi-block writes are in the pipeline for the main-line kernel in 2.6.20.

Thanks, look forward to seeing your diffs.

updated http://fanoush.webpark.cz/maemo/#mmcplus with source diff for newer kernel

Outstanding, thanks!
