This is a follow-up to http://www.spinics.net/lists/sparclinux/msg13443.html All sparc iommu usage (LDC, sun4u, sun4v) has now been converted to the new library. The one and only struct iommu for sparc uses the iommu_table defined in iommu-common.c. I tested this on a sunfire (V440) and an ultra-45, in addition to a T5, and LDOMS, but I could use more testing help for the legacy platforms. Also, I'll be on the road a bit for the rest of the week, so will be a bit slow to handle review feedback (hence derailing this to RFC status) Patches division is as follows. Patch 1: Common library functions in lib/Makefile include/linux/iommu-common.h lib/iommu-common.c Patch 2: Converts sun4u, sun4v, PCI in sparc to use common library. Impacts arch/sparc/include/asm/iommu_64.h arch/sparc/kernel/iommu.c arch/sparc/kernel/iommu_common.h arch/sparc/kernel/pci_sun4v.c Patch 3: Converts LDC to use Patch 1. Impacts arch/sparc/kernel/ldc.c Sowmini (2): Break up monolithic iommu table/lock into finer graularity pools and lock Make sparc64 use scalable lib/iommu-common.c functions Sowmini Varadhan (1): Make LDC use common iommu poll management functions arch/sparc/include/asm/iommu_64.h | 7 +- arch/sparc/kernel/iommu.c | 194 +++++++++++--------------------- arch/sparc/kernel/iommu_common.h | 8 -- arch/sparc/kernel/ldc.c | 185 ++++++++++++++++--------------- arch/sparc/kernel/pci_impl.h | 7 +- arch/sparc/kernel/pci_sun4v.c | 207 +++++++++++++++++------------------ include/linux/iommu-common.h | 56 ++++++++++ lib/Makefile | 2 +- lib/iommu-common.c | 220 +++++++++++++++++++++++++++++++++++++ 9 files changed, 550 insertions(+), 336 deletions(-) create mode 100644 include/linux/iommu-common.h create mode 100644 lib/iommu-common.c -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
