Readahead for HD Video Playback CIFS/NFS/FTP over Wi-Fi

[arris69]

...
Arris, would it be possible to include ftp fs (e.g. lufs) in the next release of SamyGO All Ext? I tried to compile it but it needs kernel headers which I do not know where to find...

looks as outdated software:

why do you not try tuning over /proc or module/mount parameter for cifs?

btw here is a bb file to start with if you like try to patch lufs ( save it as lufs_0.9.7.bb)

Code: Select all

DESCRIPTION=Linux Userland File Systems
SECTION=base
PRIORITY=optional
LICENSE=GPL

SRC_URI = "\
        ${SOURCEFORGE_MIRROR}/lufs/lufs-${PV}.tar.gz \

S = ${WORKDIR}/lufs-${PV}

inherit autotools pkgconfig module

EXTRA_OECONF = --with-kernel=${KERNEL_VERSION} --with-kheaders=${STAGING_KERNEL_DIR}/include

should not just this patch be applied simply? Is it commented out in the .bb file by intention?

Do you mean CIFSMaxbuffsize, rsize? I've tried that already without any success. Maybe I have not tried that in the right way... but I do not know what are the optimal settings both on client as well as on the server side. I do not think it will fly with CIFS but I would be happy to see an evidence that it does.

lufs is the old implementation of fuse, fuse is in SamyGO svn sshfs-fuse too, so feel free to test.
now i am on rebuild my toolchain for sh4 and arm so may tomorrow i can make a look at http://curlftpfs.sourceforge.net/

ps: may from this direction: http://fasterdata.es.net/TCP-tuning/linux.html

edit, 19.feb: found other thing http://www.ricardis.tudelft.nl/~vincent/fusesmb/, so initial release of curlftpfs and fusesmb are in svn, feel free to submit patches
so it can work on tvs filesystem structure.

Upgrade to N could be an option indeed

According to this thread http://forum.samygo.tv/viewtopic.php?f=4&t=267 upgrading to N wouldn't improve the situation.

arris, thanks. I can see curlftp in the svn repo. Is a compiled binary available somewhere as well? Or how can I compile it for myself? (I assume I have to pull branch-1 from svn but then run make or bitbake with some parameter?) sorry for the lame question...

cd build ; . ./env.source ; bitbake -v -D curlftps ; cd -

or you modifi one of the image recipe (under oe/packages/images/) and add curlftpfs to INSTALL_PACKAGES than
cd build ; . ./env.source ; bitbake -v -D <whatewerrecipe> ; cd -

if you build image targets you can find installed binaries under build/tmp/rootfs if you build just target recipe like curlftpfs you can find compiled binaries somewhere under build/tmp/work/ or ipkg under build/tmp/deploy/ipk

but there is also readme file with urls to openembedded in the svn

thanks. I have tried in both ways but it says:

I assume a step is missing.

delete the file oe/packages/u-boot/u-boot-mkimage-selp-native_p750.bb and than try again pls.
assume your tv should use u-boot b650, i have to check the machine <-> u-boot stuff
