Revision 30f92d62e5b41a94de2d0bbd677a6ea2fcfed74f authored by Akinobu Mita on 06 September 2017, 10:15:31 UTC, committed by Christoph Hellwig on 11 September 2017, 16:29:38 UTC
The initial chunk size for host memory buffer allocation is currently PAGE_SIZE << MAX_ORDER. MAX_ORDER order allocation is usually failed without CONFIG_DMA_CMA. So the HMB allocation is retried with chunk size PAGE_SIZE << (MAX_ORDER - 1) in general, but there is no problem if the retry allocation works correctly.
