As far as I see, the genalloc allocator doesn't allow to control the memory alignment when you allocate a chunk of memory. Two important notes regarding MURAM memory: - The allocated memory chunks should have specific alignment (might be different in each chunk). - The allocations must be efficient, we don't want to "waste" MURAM due to alignment issues. > - k -- 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/
RE: [v2,00/11] Freescale DPAA FMan FLIB(s)
Hello, In v2 of DPAA FMan FLIBs we've made the following updates: - Split the header patch ([v2,01/11] soc/fman: Add the FMan FLIB headers) from one big patch to smaller patches - Kumar's feedback. - Removed the KILOBYTE defines - Kumar's feedback. - Addressed several comments from Scott on [v2,02/11] soc/fman: Add the FMan FLIB.
