2020-09-30mtd: rawnand: Use the ECC framework user input parsing bitsMiquel Raynal1-72/+70
Many helpers are generic to all NAND chips, they should not be raw-NAND specific, so use the generic ones. To avoid moving all the raw NAND core "history" into the generic NAND layer, we keep a part of this parsing in the raw NAND core to ensure backward compatibility.

The use of "syndrome" placement should not be encoded in the ECC engine mode/type.

2020-09-02mtd: nand: Introduce the ECC engine frameworkMiquel Raynal3-0/+494
Create a generic ECC engine framework. This is a base to instantiate ECC engine objects. If we really want to be generic, bindings must evolve, so here is the new logic. The following three properties are mutually exclusive: - The nand-no-ecc-engine boolean property is set and there is no ECC engine to retrieve. - The nand-use-soft-ecc-engine boolean property is set and the core will force using the use of software correction. - There is a nand-ecc-engine property pointing at a node which will act as ECC engine. It the later case, the property may reference: - The NAND chip node itself (for the on-die ECC case). - The parent node if the NAND controller embeds an ECC engine. - Any other node being an external ECC controller as well.

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.

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.

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 Wan1-0/+1
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.

2020-08-20opp: Enable resources again if they were disabled earlierRajendra Nayak1-4/+7
dev_pm_opp_set_rate() can now be called with freq = 0 in order to either drop performance or bandwidth votes or to disable regulators on platforms which support them. In such cases, a subsequent call to dev_pm_opp_set_rate() with the same frequency ends up returning early because 'old_freq == freq' Instead make it fall through and put back the dropped performance and bandwidth votes and/or enable back the regulators.

Commit 8dcf2ad39fdb2 ("net: atlantic: add hwmon getter for MAC temperature") implemented a read callback with an udelay(10000U). This fails to compile on ARM because the delay is >1ms. I doubt that it is needed to spin for 10ms even if possible on x86. >From looking at the code, the context appears to be preemptible so using usleep() should work and avoid busy spinning.

2020-08-19net: ena: Change WARN_ON expression in ena_del_napi_in_range()Shay Agroskin1-7/+4
The ena_del_napi_in_range() function unregisters the napi handler for rings in a given range. This function had the following WARN_ON macro: WARN_ON(ENA_IS_XDP_INDEX(adapter, i) && adapter->ena_napi[i].xdp_ring); This macro prints the call stack if the expression inside of it is true [1], but the expression inside of it is the wanted situation. The expression checks whether the ring has an XDP queue and its index corresponds to a XDP one. This patch changes the expression to !ENA_IS_XDP_INDEX(adapter, i) && adapter->ena_napi[i].xdp_ring which indicates an unwanted situation. Also, change the structure of the function. The napi handler is unregistered for all rings, and so there's no need to check whether the index is an XDP index or not. By removing this check the code becomes much more readable.
