Hello,
I am using Linux kernel 2.4.19 on a MPC8260 and I was wondering why the
FCC code does not use the Dual Port RAM to store the Buffer Descriptors?
Instead it uses regular host memory.
In arch\ppc\8260_io\fcc_enet.c it states :
/* I really want to do this, but for some reason it doesn't
* work with the data cache enabled, so I allocate from the
* main memory instead.
*/
inside of the init_fcc_param routine.
Thanks,
John Penn
