Hello,
I'm still trying to use Flac with Maverick crunch support on my EP9312 board.
First of all, I don't know which kernel I should use : the official cirrus'
2.6.8.1 or the linux-cirrus-2.6.11-nucleus-patched.
I've found some strange things in cirrus-2.6.8.1 :
in file arch/arm/mach-ep93xx/crunch.c, the code relative to crunch accumulators
is compiled if 'CONFIG_EP93XX_CRUNCH_ACC' is defined, but this tag is not
present in any of the other files in the kernel source tree. And the struct
fp_crunch_struct used in this file isn't defined anywhere.
CONFIG_EP93XX_CRUNCH_ACC is neither present in Nucleus' kernel patch, but struct
fp_crunch_struct is.
I don't have access to the nucleus patched kernel tree right know, but I guess
that if CONFIG_EP93XX_CRUNCH_ACC is not in the Nucleus patch, it is not in the
2.6.11 kernel tree. Thus the accumulator relative code is never used (at least
save_accumulators & restore_accumulators functions).
Does anybody know if this is the way it should be ? Maybe
(save|restore)_accumulators functions are not usefull ?
Regards
Yann
