Re: [Ac100] unscientific eMMC read speed test
yes, seems that the caching subsystem has some negative footprint. See e.g. https://lkml.org/lkml/2011/5/25/499 Is there a way of enabling this for all reads system wide without having to use O_DIRECT in all apps libs explicitly? I think this could be used to improve boot time Jani ___ Mailing list: https://launchpad.net/~ac100 Post to : ac100@lists.launchpad.net Unsubscribe : https://launchpad.net/~ac100 More help : https://help.launchpad.net/ListHelp

[Ac100] suspend breakage vs android 2.2 bootloader?
Following current discussion in the IRC channel let's see if the two are related I know I upgraded to Android 2.2 before flashing linux and I have non working suspend now. I wonder if others who have suspend/resume broken are in the same situation?

Re: [Ac100] suspend breakage vs android 2.2 bootloader?
I reflashed the Android 2.1 boot partitions and suspend works now! Mistery solved but a proper kernel fix is needed imo to cover the bits that may have been set up by 2.1 for free :) This sequence worked after two trials which left the machine non-bootable. I used an explicitly separate step for downloading fastboot, then waited a bit after the last command. sudo LD_LIBRARY_PATH=. ./nvflash --bl fastboot.bin --go sudo LD_LIBRARY_PATH=. ./nvflash --bl ./fastboot.bin --go --rawdevicewrite 0 1536 tac100-part-2.img sudo LD_LIBRARY_PATH=. ./nvflash --bl ./fastboot.bin --go --rawdevicewrite 1536 256 tac100-part-3.img sudo LD_LIBRARY_PATH=. ./nvflash --bl ./fastboot.bin --go --rawdevicewrite 1792 1024 tac100-part-4.img Here's a tarball of these 3 partitions as factory defaults for the 10z model - should be same for all but who knows. http://startx.ro/~jani/bootparts_ac100_z.tgz Jani On Tue, Sep 27, 2011 at 3:16 PM, Leon Romanovsky l...@leon.nu wrote: On Tue, Sep 27, 2011 at 15:04, Jani Monoses jani.mono...@gmail.com wrote: Following current discussion in the IRC channel let's see if the two are related I know I upgraded to Android 2.2 before flashing linux and I have non working suspend now.
