Dear list, I am working on a memory corruption problem with a patched 2.6.21 kernel in the USB driver. In order to better understand the problem I would like to ask how current kernels handle the case where the same cacheline is used for a DMA-able object and another object.
Does kmalloc return only memory that is cache line aligned? If not, do all architectures handle cache line misalign ed dma accesses correctly like the powerpc (although not yet in 2.6.21) architecture does? Thanks for any insights. - Johannes PS: Please CC me I am not on the list. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
