[RFC PATCH 0/2] sched/topology: Get rid of overlapping groups
by Valentin Schneider 09 Feb '21

09 Feb '21

Hi folks, My keyboard still hasn't been taken away from me, so I went down and did what I was rambling about in [1]. The preemptive degeneration check is the worst wart, but I think I'll have to sleep on it before I can figure out a better way. Something tells me the increase in group numbers isn't going to make me any friends, so I've included 3/2 which is Barry's approach (with the subset check condensed in a single spot). Cheers, Valentin [1]: http://lore.kernel.org/r/jhj4kiu4hz8.mognet@arm.com Valentin Schneider (2): sched/topology: Get rid of NUMA overlapping groups Revert "sched/topology: Warn when NUMA diameter > 2" kernel/sched/topology.c | 77 +++++++++++++++++++++++------------------ 1 file changed, 43 insertions(+), 34 deletions(-) -- 2.27.0

[PATCH for-next 00/12] RDMA/hns: Updates for 5.12
by Weihang Li 09 Feb '21

09 Feb '21

As usual, this series collects some miscellaneous fixes and cleanups at the end of 5.12 for the hns driver: * #1 ~ #3 fix some non-urgent issues. * #4 ~ #6 make some changes on existing features. * #7 ~ #12 are cleanups, just do some refactor and delete dead code. This series is made based on the series named "RDMA/hns: Several fixes and cleanups of RQ/SRQ" which is still being reviewed: https://patchwork.kernel.org/project/linux-rdma/cover/1611997090-48820-1-gi… I'm worried that it will be too late for 5.12 if any patch of this series needs changes, so I send it before the previous one is merged. If there is any comment or merge conflict on it, I will fix them as soon as possible, thanks. Lang Cheng (3): RDMA/hns: Replace wmb&__raw_writeq with writeq RDMA/hns: Move HIP06 related definitions into hns_roce_hw_v1.h RDMA/hns: Avoid unnecessary memset on WQEs in post_send Lijun Ou (1): RDMA/hns: Disable RQ inline by default Weihang Li (2): RDMA/hns: Avoid filling sgid index when modifying QP to RTR RDMA/hns: Fix type of sq_signal_bits Xi Wang (1): RDMA/hns: Add mapped page count checking for MTR Xinhao Liu (2): RDMA/hns: Remove some magic numbers RDMA/hns: Delete redundant judgment when preparing descriptors Yixian Liu (1): RDMA/hns: Remove unnecessary wrap around for EQ's consumer index Yixing Liu (2): RDMA/hns: Adjust definition of FRMR fields RDMA/hns: Skip qp_flow_control_init() for HIP09 drivers/infiniband/hw/hns/hns_roce_device.h | 45 +--------- drivers/infiniband/hw/hns/hns_roce_hem.c | 9 +- drivers/infiniband/hw/hns/hns_roce_hw_v1.c | 31 +++---- drivers/infiniband/hw/hns/hns_roce_hw_v1.h | 43 ++++++++++ drivers/infiniband/hw/hns/hns_roce_hw_v2.c | 125 +++++++++------------------- drivers/infiniband/hw/hns/hns_roce_hw_v2.h | 12 +-- drivers/infiniband/hw/hns/hns_roce_main.c | 16 ---- drivers/infiniband/hw/hns/hns_roce_mr.c | 56 ++++++++----- 8 files changed, 148 insertions(+), 189 deletions(-) -- 2.8.1

[PATCH v1 0/2] irqchip/gic-v3-its: don't set bitmap for LPI which user didn't allocate
by Luo Jiaxing 09 Feb '21

09 Feb '21

When the number of online CPUs is less than 16, we found that it will fail to allocate 32 MSI interrupts (including 16 affinity interrupts) after the hisi_sas module is unloaded and then reloaded. After analysis, it is found that a bug exists when the ITS releases interrupt resources, and this patch set contains a bugfix patch and a patch for appending debugging information.

[dpdk-dev] [Question about 'rte_eth_tx_prepare']
by Chengchang Tang 09 Feb '21

09 Feb '21

Hi, Thomas Monjalon and Ferruh Yigit and others. I have some questions about 'rte_eth_tx_prepare'. When I use TSO offload in bond mode, the checksum error occurs. It is because the bond PMD does not implement 'tx_prepare'. So, it will not invoke the 'tx_prepare' of each PMDs to do prepare for the PMDs. I am not sure whether to add the 'tx_preapre' implementation for the bond PMD or put the process of pseudo header in the apps. And we are now designing the outer UDP cksum offload for HNS3 PMD. I find that many PMDs process these pseudo headers in 'tx_prepare', but does not process the pseudo header for outer UDP checksum offload. Instead, it is processed in csum forward mode of testpmd. Does this mean that the pseudo header should be completed by the apps and the apps does not need to call 'tx_prepare' to avoid repeated processing? (it seems not transplantable) If so, it seems that PMDs need to avoid doing this in 'tx_prepare'. Here are two questions: 1. What functions should be included in the 'tx_prepare' for PMDs? 2. Whether an app must invoke 'rte_eth_tx_prepare' or under which conditions an app must invoke the 'rte_eth_tx_prepare'? Thanks Chengchang Tang

[PATCH v2 for-next] RDMA/hns: Add support of direct wqe

From: Yixing Liu <liuyixing1(a)huawei.com> Direct wqe is a mechanism to fill wqe directly into the hardware.

[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.

[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

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().

[RFC PATCH 0/4] hw/cxl/ + /hw/pci/: PCI DOE + CXL CDAT emulation
by Jonathan Cameron 04 Feb '21

04 Feb '21

Whilst I know others are working on an implementation of at least some of this, a desire to work on the kernel user of this required an implementation so I threw this together in the meantime and am sending it out on the basis that it may be of use to others. As it is an RFC I have been lazy on some cleanup and error handling. Will fix that in a future version if we decide to take this forwards. Based on Ben's cxl-2.0v3 branch from https://gitlab.com/bwidawsk/qemu Possible I've picked an unstable branch so this may or may not currently apply :) I'll rebase on Ben's next version when avaialble.

[RFC PATCH 0/3] hw/arm/virt: CXL enablement including gpex-acpi
by Jonathan Cameron 04 Feb '21

04 Feb '21

Very basic initial enablement of CXL on arm virt with relevant ACPI table construction. Includes changes in gpex-acpi to ensure correct DSDT for any pci_expand_bridge/pxb-cxl bridges. Note not looking to do the primary root bridge yet. Based on Ben's tree cxl-2.0v3 at https://gitlab.com/bwidawsk/qemu To actually get the memory appropriately exposed to the OS a few additional changes are needed as discussed in thread https://lore.kernel.org/qemu-devel/20210128174009.00007536@Huawei.com/ I will rebase this on future versions of Ben's series as needed.

"If control of this feature was requested and denied, or was not requested, the firmware returns this bit set to 0." We store bit 7 of _OSC control return value in host->native_dpc, check it before enable the dpc service as the firmware may not grant the control.
