[PATCH v2 RFC 0/7] RDMA/hns: Add support for Dynamic Context Attachment
by Weihang Li 07 Feb '21

07 Feb '21

The hip09 introduces the DCA(Dynamic Context Attachment) feature which supports many RC QPs to share the WQE buffer in a memory pool. If a QP enables DCA feature, the WQE's buffer will not be allocated when creating but when the users start to post WRs. This will reduce the memory consumption when there are too many QPs are inactive. Changes since v1: * Replace all GFP_ATOMIC with GFP_NOWAIT, because the former may use emergency pool if no regular memory can be found. * Change size of cap_flags of alloc_ucontext_resp from 32 to 64 to avoid a potential problem when pass it back to the userspace. * Move definition of HNS_ROCE_CAP_FLAG_DCA_MODE to hns-abi.h. * Rename free_mem_states() to free_dca_states() in #1. * Link: https://patchwork.kernel.org/project/linux-rdma/cover/1610706138-4219-1-git… Xi Wang (7): RDMA/hns: Introduce DCA for RC QP RDMA/hns: Add method for shrinking DCA memory pool RDMA/hns: Configure DCA mode for the userspace QP RDMA/hns: Add method for attaching WQE buffer RDMA/hns: Setup the configuration of WQE addressing to QPC RDMA/hns: Add method to detach WQE buffer RDMA/hns: Add method to query WQE buffer's address drivers/infiniband/hw/hns/Makefile | 2 +- drivers/infiniband/hw/hns/hns_roce_dca.c | 1264 +++++++++++++++++++++++++++ drivers/infiniband/hw/hns/hns_roce_dca.h | 68 ++ drivers/infiniband/hw/hns/hns_roce_device.h | 31 + drivers/infiniband/hw/hns/hns_roce_hw_v2.c | 223 ++++- drivers/infiniband/hw/hns/hns_roce_hw_v2.h | 3 + drivers/infiniband/hw/hns/hns_roce_main.c | 27 +- drivers/infiniband/hw/hns/hns_roce_qp.c | 119 ++- include/uapi/rdma/hns-abi.h | 64 ++ 9 files changed, 1754 insertions(+), 47 deletions(-) create mode 100644 drivers/infiniband/hw/hns/hns_roce_dca.c create mode 100644 drivers/infiniband/hw/hns/hns_roce_dca.h -- 2.8.1

[PATCH v3 1/2] dma-mapping: benchmark: use u8 for reserved field in uAPI structure
by Barry Song 05 Feb '21

05 Feb '21

The original code put five u32 before a u64 expansion[10] array. Five is odd, this will cause trouble in the extension of the structure by adding new features. This patch moves to use u8 for reserved field to avoid future alignment risk. Meanwhile, it also clears the memory of struct map_benchmark in tools, otherwise, if users use old version to run on newer kernel, the random expansion value will cause side effect on newer kernel.

[PATCH v2] dma-mapping: benchmark: pretend DMA is transmitting
by Barry Song 05 Feb '21

05 Feb '21

In a real dma mapping user case, after dma_map is done, data will be transmit. Thus, in multi-threaded user scenario, IOMMU contention should not be that severe. For example, if users enable multiple threads to send network packets through 1G/10G/100Gbps NIC, usually the steps will be: map -> transmission -> unmap. Transmission delay reduces the contention of IOMMU. Here a delay is added to simulate the transmission between map and unmap so that the tested result could be more accurate for TX and simple RX. A typical TX transmission for NIC would be like: map -> TX -> unmap since the socket buffers come from OS. Simple RX model eg. disk driver, is also map -> RX -> unmap, but real RX model in a NIC could be more complicated considering packets can come spontaneously and many drivers are using pre-mapped buffers pool. This is in the TBD list.

[PATCH] perf metricgroup: Fix system PMU metrics
by John Garry 05 Feb '21

05 Feb '21

Joakim reports that getting "perf stat" for multiple system PMU metrics segfaults: ./perf stat -a -I 1000 -M imx8mm_ddr_write.all,imx8mm_ddr_write.all Segmentation fault While the same works without issue for a single metric. The logic in metricgroup__add_metric_sys_event_iter() is broken, in that add_metric() @m argument should be NULL for each new metric. Fix by not passing a holder for that, and rather make local in metricgroup__add_metric_sys_event_iter().
