2014-01-16ixgbevf: use pci drvdata correctly in ixgbevf_suspend()Wei Yongjun
We had set the pci driver-specific data in ixgbevf_probe() as a type of struct net_device, so we should use it as netdev in ixgbevf_suspend().

2014-01-16ixgbevf: set the disable state when ixgbevf_qv_disable is calledJacob Keller
The ixgbevf_qv_disable function used by CONFIG_NET_RX_BUSY_POLL is broken, because it does not properly set the IXGBEVF_QV_STATE_DISABLED bit, indicating that the q_vector should be disabled (and preventing future locks from obtaining the vector). This patch corrects the issue by setting the disable state.

2013-11-14Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

2013-09-21DMA-API: net: intel/ixgbevf: fix 32-bit DMA mask handlingRussell King
The fallback to 32-bit DMA mask is rather odd: if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) && !dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) { pci_using_dac = 1; } else { err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) { err = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) { dev_err(&pdev->dev, "No usable DMA " "configuration, aborting\n"); goto err_dma; } } pci_using_dac = 0; } This means we only set the coherent DMA mask in the fallback path if the DMA mask set failed, which is silly. This fixes it to set the coherent DMA mask only if dma_set_mask() succeeded, and to error out if either fails.

2013-03-26ixgbevf: don't release the soft entriesxunleer
When the ixgbevf driver is opened the request to allocate MSIX irq vectors may fail. In that case the driver will call ixgbevf_down() which will call ixgbevf_irq_disable() to clear the HW interrupt registers and calls synchronize_irq() using the msix_entries pointer in the adapter structure. However, when the function to request the MSIX irq vectors failed it had already freed the msix_entries which causes an OOPs from using the NULL pointer in synchronize_irq(). The calls to pci_disable_msix() and to free the msix_entries memory should not occur if device open fails. Instead they should be called during device driver removal to balance with the call to pci_enable_msix() and the call to allocate msix_entries memory during the device probe and driver load.

2013-03-08ixgbevf: Make next_to_watch a pointer and adjust memory barriers to avoid racesAlexander Duyck
This change is meant to address several race issues that become possible because next_to_watch could possibly be set to a value that shows that the descriptor is done when it is not. In order to correct that we instead make next_to_watch a pointer that is set to NULL during cleanup, and set to the eop_desc after the descriptor rings have been written. To enforce proper ordering the next_to_watch pointer is not set until after a wmb writing the values to the last descriptor in a transmit. In order to guarantee that the descriptor is not read until after the eop_desc we use the read_barrier_depends which is only really necessary on the alpha architecture.

2012-11-13ixgbevf: Reduce size of maximum rx bufferGreg Rose
There's no need to support up to 15k buffers since the HW is limited to 9.5k in SR-IOV mode. Instead, allocate buffers that fit and align inside of a 32K memory buffer.

2012-11-13ixgbevf: Add flag to indicate when rx is in net pollGreg Rose
napi_gro_receive shouldn't be called from netpoll context. Doing so was causing kernel panics when jumbo frames larger than 2K were set. Add a flag to check if the Rx ring processing is occurring from interrupt context or from netpoll context and call netif_rx() if in the polling context.
