2015-07-30iommu/amd: Set global dma_ops if swiotlb is disabledJoerg Roedel
Some AMD systems also have non-PCI devices which can do DMA. Those can't be handled by the AMD IOMMU, as the hardware can only handle PCI. These devices would end up with no dma_ops, as neither the per-device nor the global dma_ops will get set. SWIOTLB provides global dma_ops when it is active, so make sure there are global dma_ops too when swiotlb is disabled. Signed-off-by: Joerg Roedel <jroedel@suse.de>
2015-07-30iommu/amd: Use swiotlb in passthrough modeJoerg Roedel
In passthrough mode (iommu=pt) all devices are identity mapped. If a device does not support 64bit DMA it might still need remapping. Make sure swiotlb is initialized to provide this remapping. Signed-off-by: Joerg Roedel <jroedel@suse.de>
2015-07-30iommu/amd: Allow non-IOMMUv2 devices in IOMMUv2 domainsJoerg Roedel
Since devices with IOMMUv2 functionality might be in the same group as devices without it, allow those devices in IOMMUv2 domains too. Otherwise attaching the group with the IOMMUv2 device to the domain will fail. Signed-off-by: Joerg Roedel <jroedel@suse.de>

2015-07-30iommu/amd: Use iommu_attach_group()Joerg Roedel
Since the conversion to default domains the iommu_attach_device function only works for devices with their own group. But this isn't always true for current IOMMUv2 capable devices, so use iommu_attach_group instead. Signed-off-by: Joerg Roedel <jroedel@suse.de>

Jiri Pirko says: ==================== Introduce Mellanox Technologies Switch ASICs switchdev drivers This patchset introduces Mellanox Technologies Switch driver infrastructure and support for SwitchX-2 ASIC. The driver is divided into 3 logical parts: 1) Bus - implements switch bus interface. Currently only PCI bus is implemented, but more buses will be added in the future. Namely I2C and SGMII. (patch #2) 2) Driver - implemements of ASIC-specific functions. Currently SwitchX-2 ASIC is supported, but a plan exists to introduce support for Spectrum ASIC in the near future. (patch #4) 3) Core - infrastructure that glues buses and drivers together. It implements register access logic (EMADs) and takes care of RX traps and events.

2015-07-30mlxsw: Add interface to access registers and process eventsIdo Schimmel
Ethernet Management Datagrams (EMADs) are Ethernet packets sent between the host and the device in order to configure the available device registers. Another use case is notifications sent from the device to the host, letting it know about certain events, such as port up / down. Add the ability to construct EMADs with provisions to construct and parse the registers' payloads. Implement EMAD transaction layer which is responsible for the reliable transmission of EMADs. Also, add an infrastructure used by the switch driver to register for particular events generated by the device.

2015-07-29net: thunderx: Fix RQ_DROP miscalculationSunil Goutham
With earlier configured value sufficient number of CQEs are not being reserved for transmitted packets. Hence under heavy incoming traffic load, receive notifications will take away most of the CQ thus transmit notifications will be lost resulting in tx skbs not being freed. Finally SQ will be full and it will be stopped, watchdog timer will kick in. After this fix receive notifications will not take morethan half of CQ reserving the rest for transmit notifications. Also changed CQ & SQ sizes from 16k to 4k. This is also due to the receive notifications taking first half of CQ under heavy load and time taken by NAPI to clear transmit notifications will increase with higher queue sizes. Again results in SQ being stopped. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: Aleksey Makarov <aleksey.makarov@caviumnetworks.com> Signed-off-by: David S.

2015-07-29net/mlx5e: Remove the mlx5e_update_priv_params() functionAchiad Shochat
It was used to update netdev priv parameters that require stopping and re-opening the device in a generic way - it got the new parameters and did: ndo_stop(), copy new parameters into current parameters, ndo_open(). We chose to remove it for two reasons: 1) It requires additional instance of struct mlx5e_params on the stack and looking forward we expect this struct to grow. 2) Sometimes we want to do additional operations (besides just updating the priv parameters) while the netdev is stopped. For example, updating netdev->mtu @mlx5e_change_mtu() should be done while the netdev is stopped (done in this commit).

As part of defconfig consolidation using fragments, we'd like to be able to have the same drivers enabled on 32-bit and 64-bit. Gianfar happens to only exist on 32-bit systems, and when building the resulting 64-bit kernel warnings were produced. A couple of the warnings are trivial, but the rfbptr code has deeper issues. It uses the virtual address as the DMA address, which again, happens to work in the environments where this driver is currently used, but is not the right thing to do.
