Christoph, Please review, thanks! > * Set the coherent dma mask to 64 bit and then allocate RDPQ pools, > make sure that each of the RDPQ pools satisfies the 4gb boundary > restriction. if any of the RDPQ pool doesn't satisfies this > restriction then deallocate the pools and reallocate them after > changing the coherent dma mask to 32 bit. > * With this there is no need to change DMA coherent > mask when there are outstanding allocations in mpt3sas. > * Code-Refactoring > > Suganath Prabu S (5): > mpt3sas: Don't change the dma coherent mask after allocations > mpt3sas: Rename function name is_MSB_are_same > mpt3sas: Separate out RDPQ allocation to new function. > mpt3sas: Handle RDPQ DMA allocation in same 4G region > mpt3sas: Update mpt3sas version to 33.101.00.00 > > drivers/scsi/mpt3sas/mpt3sas_base.c | 279 +++++++++++++++++++++--------------- > drivers/scsi/mpt3sas/mpt3sas_base.h | 9 +- > 2 files changed, 171 insertions(+), 117 deletions(-) -- Martin K.
