Memory BAT and PPC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello everyone.

I am working on an ethernet driver and I am trying to allocate memory that won't get cached.  Problem is sometimes when I allocate memory it comes from the "BAT" pool.  That is the block address translation pool.  This is something particular to the PPC platform.

Unfortunately, the BAT pool is cached memory.  So what I'm thinking is that I need to get memory allocated NOT from the BAT pool.

Has anyone else dealt with this.

I am doing this in the 2.6.10 kernel.

Thanks.
