2020-09-07drm/i915: Reduce i915_request.lock contention for i915_request_waitChris Wilson
Currently, we use i915_request_completed() directly in i915_request_wait() and follow up with a manual invocation of dma_fence_signal(). This appears to cause a large number of contentions on i915_request.lock as when the process is woken up after the fence is signaled by an interrupt, we will then try and call dma_fence_signal() ourselves while the signaler is still holding the lock. dma_fence_is_signaled() has the benefit of checking the DMA_FENCE_FLAG_SIGNALED_BIT prior to calling dma_fence_signal() and so avoids most of that contention.

2020-08-21drm/tidss: implement WA for AM65xx erratum i2000Tomi Valkeinen
This patch implements WA for AM65xx erratum i2000, which causes YUV formats to show wrong colors. An earlier patch removed a partial WA: a8d9d7da1546349f18eb2d6b6b3a04bdeb38719d ("drm/tidss: remove AM65x PG1 YUV erratum code") The patch explains the reasoning for removal. The change in plans has been that it has become clear that there are and will be users for PG1 SoCs and as such it's good to implement the WA for PG1s. This patch adds the WA back so that it is only used on SR1.0 (which is the new name for PG1). The previous WA code didn't check the SoC revision, which this patch does.

2020-08-20hv_netvsc: Fix the queue_mapping in netvsc_vf_xmit()Haiyang Zhang
netvsc_vf_xmit() / dev_queue_xmit() will call VF NIC’s ndo_select_queue or netdev_pick_tx() again. They will use skb_get_rx_queue() to get the queue number, so the “skb->queue_mapping - 1” will be used. This may cause the last queue of VF not been used. Use skb_record_rx_queue() here, so that the skb_get_rx_queue() called later will get the correct queue number, and VF will be able to use all queues.

2020-08-20RISC-V: Remove CLINT related code from timer and archAnup Patel
Right now the RISC-V timer driver is convoluted to support: 1. Linux RISC-V S-mode (with MMU) where it will use TIME CSR for clocksource and SBI timer calls for clockevent device. 2. Linux RISC-V M-mode (without MMU) where it will use CLINT MMIO counter register for clocksource and CLINT MMIO compare register for clockevent device. We now have a separate CLINT timer driver which also provide CLINT based IPI operations so let's remove CLINT MMIO related code from arch/riscv directory and RISC-V timer driver.

We add a separate CLINT timer driver for Linux RISC-V M-mode (i.e. RISC-V NoMMU kernel). The CLINT MMIO device provides three things: 1. 64bit free running counter register 2. 64bit per-CPU time compare registers 3. 32bit per-CPU inter-processor interrupt registers Unlike other timer devices, CLINT provides IPI registers along with timer registers. To use CLINT IPI registers, the CLINT timer driver provides IPI related callbacks to arch/riscv.

2020-08-20RDMA/hfi1: Correct an interlock issue for TID RDMA WRITE requestKaike Wan
The following message occurs when running an AI application with TID RDMA enabled: hfi1 0000:7f:00.0: hfi1_0: [QP74] hfi1_tid_timeout 4084 hfi1 0000:7f:00.0: hfi1_0: [QP70] hfi1_tid_timeout 4084 The issue happens when TID RDMA WRITE request is followed by an IB_WR_RDMA_WRITE_WITH_IMM request, the latter could be completed first on the responder side. As a result, no ACK packet for the latter could be sent because the TID RDMA WRITE request is still being processed on the responder side. When the TID RDMA WRITE request is eventually completed, the requester will wait for the IB_WR_RDMA_WRITE_WITH_IMM request to be acknowledged. If the next request is another TID RDMA WRITE request, no TID RDMA WRITE DATA packet could be sent because the preceding IB_WR_RDMA_WRITE_WITH_IMM request is not completed yet. Consequently the IB_WR_RDMA_WRITE_WITH_IMM will be retried but it will be ignored on the responder side because the responder thinks it has already been completed. Eventually the retry will be exhausted and the qp will be put into error state on the requester side. On the responder side, the TID resource timer will eventually expire because no TID RDMA WRITE DATA packets will be received for the second TID RDMA WRITE request. There is also risk of a write-after-write memory corruption due to the issue. Fix by adding a requester side interlock to prevent any potential data corruption and TID RDMA protocol error.
