The following series, which builds upon the series of cleanups I posted on 9/15 and 10/18 as "ppc iommu cleanups", enables the pseries firmware feature dynamic dma windows. This feature will allow future devices to have a 64-bit DMA mapping covering all memory, coexisting with a smaller IOMMU window in 32-bit PCI space
Changes from v1 to v2: Fixed numerous bugs/issues found in testing. Reworked to be based off platform hook dma_set_mask(). Nishanth Aravamudan (7): macio: ensure all dma routines get copied over ppc: add memory_hotplug_max ppc: do not search for dma-window property on dlpar remove ppc: checking for pdn->parent is redundant ppc/iommu: do not need to check for dma_window == NULL ppc/iommu: pass phb only to iommu_table_setparms_lpar ppc: add dynamic dma window support arch/powerpc/include/asm/device.h | 6 + arch/powerpc/include/asm/mmzone.h | 5 + arch/powerpc/mm/numa.c | 26 ++ arch/powerpc/platforms/pseries/iommu.c | 600 ++++++++++++++++++++++++++++++-- drivers/macintosh/macio_asic.c | 7 +- 5 files changed, 619 insertions(+), 25 deletions(-) _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
