From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sowmini Varadhan Date: Tue, 24 Mar 2015 17:10:27 +0000 Subject: [PATCH v6 0/3] Generic IOMMU pooled allocator Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: sparclinux@vger.kernel.org Cc: aik@au1.ibm.com, anton@au1.ibm.com, paulus@samba.org, sowmini.varadhan@oracle.com, linuxppc-dev@lists.ozlabs.org, davem@davemloft.net Deltas from patchv5: - removed iommu_tbl_ops, and instead pass the ->flush_all as an indirection to iommu_tbl_pool_init() - only invoke ->flush_all when there is no large_pool, based on the assumption that large-pool usage is infrequently encountered. 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 | 182 ++++++++++--------------------- arch/sparc/kernel/iommu_common.h | 8 -- arch/sparc/kernel/ldc.c | 169 ++++++++++++++--------------- arch/sparc/kernel/pci_sun4v.c | 192 ++++++++++++++++----------------- include/linux/iommu-common.h | 49 ++++++++ lib/Makefile | 2 +- lib/iommu-common.c | 219 +++++++++++++++++++++++++++++++++++++ 8 files changed, 503 insertions(+), 325 deletions(-) create mode 100644 include/linux/iommu-common.h create mode 100644 lib/iommu-common.c
