* drivers: Remove explicit invocations of mmiowb()Will Deacon2019-04-081-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

* liquidio: fix race condition in instruction completion processingRick Farrington2018-08-301-2/+3
| | | | | | | | | | | | In lio_enable_irq, the pkt_in_done count register was being cleared to zero. However, there could be some completed instructions which were not yet processed due to budget and limit constraints. So, only write this register with the number of actual completions that were processed.

* liquidio: replace info-pointer mode with buffer-pointer-only modePrasad Kanneganti2017-06-191-6/+4Star
| | | | | | | | | | | | | | | | | | | | | Each Octeon output ring can DMA packets to host memory in two modes: info- pointer mode and buffer-pointer-only mode. In info-pointer mode, Octeon takes two buffer pointers for each packet and places the length of the packet along with specified number of bytes from the beginning of the packet into one buffer and the rest of the packet in a separate buffer. In buffer-pointer-only mode, Octeon takes single buffer pointer and places the length of the packet at the beginning of the buffer followed by the packet data. This patch switches all Octeon output rings from info-pointer mode to buffer-pointer-only mode. This results in fewer DMA setups and cache line snoops.

* liquidio: fix insmod failure when multiple NICs are plugged inRick Farrington2017-05-171-6/+81
| | | | | | | | | | | | | | | When multiple liquidio NICs are plugged in, the first insmod of the PF driver succeeds. But after an rmmod, a subsequent insmod fails. Reason is during rmmod, the PF driver resets the Octeon of only one of the NICs; it neglects to reset the Octeons of the other NICs. Fix the insmod failure by adding the missing Octeon resets at rmmod. Keep a per-NIC refcount that indicates the number of active PFs in a given NIC. When the refcount goes to zero, then reset the Octeon of that NIC.

* net:liquidio: use kmemdupMuhammad Falak R Wani2016-05-211-3/+1Star
| | | | | | | | | Use kmemdup when some other buffer is immediately copied into allocated region. It replaces call to allocation followed by memcpy, by a single call to kmemdup. Signed-off-by: Muhammad Falak R Wani <falakreyaz@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net-Liquidio: Delete unnecessary checks before the function call "vfree"Markus Elfring2015-06-291-8/+3Star

* Add support of Cavium Liquidio ethernet adaptersRaghu Vatsavayi2015-06-111-0/+1307
Following patch V8 adds support for Cavium Liquidio pci express based 10Gig ethernet adapters. 1) Consolidated all debug macros to either call dev_* or netdev_* macros directly, feedback from previous patch. 2) Changed soft commands to avoid crash when running in interrupt context. 3) Fixed link status not reflecting correct status when NetworkManager is running. Added MODULE_FIRMWARE declarations. Following were the previous patches. Patch V7: 1) Minor comments from v6 release regarding debug statements. 2) Fix for large multicast lists. 3) Fixed lockup issue if port initialization fails. 4) Enabled MSI by default. https://patchwork.ozlabs.org/patch/464441/ Patch V6: 1) Addressed the uint64 vs u64 issue, feedback from previous patch. 2) Consolidated some receive processing routines. 3) Removed link status polling method. https://patchwork.ozlabs.org/patch/459514/ Patch V5: Based on the feedback from earlier patches with regards to consolidation of common functions like device init, register programming for cn66xx and cn68xx devices. https://patchwork.ozlabs.org/patch/438979/ Patch V4: Following were the changes based on the feedback from earlier patch: 1) Added mmiowb while synchronizing queue updates and other hw interactions. 2) Statistics will now be incremented non-atomically per each ring. liquidio_get_stats will add stats of each ring while reporting the total statistics counts. 3) Modified liquidio_ioctl to return proper return codes. 4) Modified device naming to use standard Ethernet naming. 5) Global function names in the driver will have lio_/liquidio_/octeon_ prefix. 6) Ethtool related changes for: Removed redundant stats and jiffies. Use default ethtool handler of link status. Speed setting will make use of ethtool_cmd_speed_set. 7) Added checks for pci_map_* return codes. 8) Check for signals while waiting in interruptible mode https://patchwork.ozlabs.org/patch/435073/ Patch v3: Implemented feedback from previous patch like: Removed NAPI Config and DEBUG config options, added BQL and xmit_more support. https://patchwork.ozlabs.org/patch/422749/ Patch V2: Implemented feedback from previous patch. https://patchwork.ozlabs.org/patch/413539/ First Patch: https://patchwork.ozlabs.org/patch/412946/ Signed-off-by: Derek Chickles <derek.chickles@caviumnetworks.com> Signed-off-by: Satanand Burla <satananda.burla@caviumnetworks.com> Signed-off-by: Felix Manlunas <felix.manlunas@caviumnetworks.com> Signed-off-by: Robert Richter <Robert.Richter@caviumnetworks.com> Signed-off-by: Aleksey Makarov <Aleksey.Makarov@caviumnetworks.com> Signed-off-by: Raghu Vatsavayi <raghu.vatsavayi@caviumnetworks.com> Signed-off-by: David S.
