fio patch question on filesetup: align layout buffer

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

 



Hi All,
I see the patch at http://git.kernel.dk/cgit/fio/commit/?id=8c43ba6259409244de64f0b1d388a029e38cf3e5 and just wondered if it is still compatible with:

.. option:: iomem_align=int, mem_align=int

	This indicates the memory alignment of the I/O memory buffers.  Note that
	the given alignment is applied to the first I/O unit buffer, if using
	:option:`iodepth` the alignment of the following buffers are given by the
	:option:`bs` used. In other words, if using a :option:`bs` that is a
	multiple of the page sized in the system, all buffers will be aligned to
	this value. If using a :option:`bs` that is not page aligned, the alignment
	of subsequent I/O memory buffers is the sum of the :option:`iomem_align` and
	:option:`bs` used.

For example, if we set mem_align to something larger than page_size or bs, what does fio_memalign use?  And if we set mem_align to something between page_size and bs, what does fio_memalign use?  Thanks.

Regards,
Jeff
