I know, but i hopefully also have a good reason to do so... First, the
attributes provided through these functions are for accessing the
firmware... The controller has a little limitation, it could only handle
64 blocks, but sysfs only have 4k...
Now there are two options:
1) when writing: read a 64k block, merge it with the 4k block and write
it back, when reading: read a 64k block and only return the needed 4k block.
2) extend the sysfs attribute to allow 64k blocks
IMHO the first is not a very good solution, because for a 64k block it
has to be written 16 times...
Of course if someone finds a better solution i would be glad to hear
about it...
Use the binary file interface of sysfs, which was written exactly for
this kind of thing. :)
Oh i tried to use the binary interface, but i haven't found a way to
increase the block size beyond 4k, could you please tell me how i could
adjust it, or where i could read about it?
Thank you very much!
Best regards,
Markus Lidel
