2016-08-29fm10k: don't try to stop queues if we've lost hw_addrJacob Keller1-0/+3
In the event of a surprise remove, we expect the driver to go down, which includes calling .stop_hw(). However, this function will return an error because the queues won't appear to cleanly disable. Prevent this and avoid the unnecessary checks by just returning when FM10K_REMOVED(hw->hw_addr) is true.

2016-08-29fm10k: don't continue probe if PCI device not in normal IO stateJacob Keller1-0/+6
In the event of an uncorrectable AER error occurring when the driver has not loaded, the recovery routines are not done. This is done because future loads of the driver may not be aware of the IO state and may not be able to recover at all. In this case, when we next load the driver it fails due to what appears to be a surprise remove event. Instead, add a check to ensure that the device is in the normal IO state before continuing to probe. This allows us to give a more descriptive message of what is wrong. Without this change, the driver will attempt to probe up to our first call of .reset_hw() which will be unable to read registers and act as if a surprise remove event occurred.

2016-08-29fm10k: NAPI polling routine must return actual work doneJacob Keller1-1/+1
When fm10k_poll fully cleans rings it returns 0. This is incorrect as it messes up the budget accounting in the core NAPI code. Fix this by returning actual work done, capped at budget - 1 since the core doesn't expect a return of the full budget when the driver modifies the NAPI status.

2016-08-29fm10k: use software values when checking for Tx hangs in hot pathJacob Keller3-6/+17
A previous patch added support to check for hardware Tx pending in the fm10k_down routine. This support was intended to ensure that we accurately check what the hardware state is. However, checking for Tx hangs in this manor during the hotpath results in a large performance hit. Avoid this by making the hotpath check use the SW counters instead.

2016-08-29fm10k: fix PCI device enable_cnt leak in .io_slot_resetJacob Keller1-1/+1
A previous patch removed the pci_disable_device() call in .io_error_detected. This call corresponded to a pci_enable_device_mem() call within .io_slot_reset handler. Change the call here to a pci_reenable_device() so that it does not increment and leak the enable_cnt reference count for the device. Without this change, VF devices may fail during an unbind/bind, and we'll never zero the reference counter for the pci_dev structure.

2016-08-29amd-xgbe: Reset running devices after resume from hibernateJames Morse1-1/+7
After resume from hibernate on arm64, any amd-xgbe devices that were running when we hibernated are reported as down, even when it is not. Re-plugging the cables does not cause the interface to come back, the link must be marked as down then up via 'ip set link' using the serial console. This happens because the device has been power-cycled and possibly re-initialised by firmware, whereas the driver's memory structures have been restored from the hibernate image and the two do not agree. Schedule a restart of the device after powerup in case the world changed while we were asleep. Signed-off-by: James Morse <james.morse@arm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-08-28net: smc91x: fix SMC accessesRussell King2-20/+52
Commit b70661c70830 ("net: smc91x: use run-time configuration on all ARM machines") broke some ARM platforms through several mistakes. Firstly, the access size must correspond to the following rule: (a) at least one of 16-bit or 8-bit access size must be supported (b) 32-bit accesses are optional, and may be enabled in addition to the above. Secondly, it provides no emulation of 16-bit accesses, instead blindly making 16-bit accesses even when the platform specifies that only 8-bit is supported. Reorganise smc91x.h so we can make use of the existing 16-bit access emulation already provided - if 16-bit accesses are supported, use 16-bit accesses directly, otherwise if 8-bit accesses are supported, use the provided 16-bit access emulation. If neither, BUG(). This exactly reflects the driver behaviour prior to the commit being fixed. Since the conversion incorrectly cut down the available access sizes on several platforms, we also need to go through every platform and fix up the overly-restrictive access size: Arnd assumed that if a platform can perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access size needed to be specified - not so, all available access sizes must be specified. This likely fixes some performance regressions in doing this: if a platform does not support 8-bit accesses, 8-bit accesses have been emulated by performing a 16-bit read-modify-write access. Tested on the Intel Assabet/Neponset platform, which supports only 8-bit accesses, which was broken by the original commit.

The driver RQ has two possible configurations: striding RQ and non-striding RQ. Until this patch, the driver always reported the number of hardware WQEs (ring descriptors). For non striding RQ configuration, this was OK since we have one WQE per pending packet For striding RQ, multiple packets can fit into one WQE. For better user experience we normalize the rx_pending parameter (size of wqe/mtu) as the average ring size in case of striding RQ. Fixes: 461017cb006a ('net/mlx5e: Support RX multi-packet WQE ...')

2016-08-28net/mlx5e: Limit UMR length to the device's limitationSaeed Mahameed4-16/+40
ConnectX-4 UMR (User Memory Region) MTT translation table offset in WQE is limited to U16_MAX, before this patch we ignored that limitation and requested the maximum possible UMR translation length that the netdev might need (MAX channels * MAX pages per channel). In case of a system with #cores > 32 and when linear WQE allocation fails, falling back to using UMR WQEs will cause the RQ (Receive Queue) to get stuck. Here we limit UMR length to min(U16_MAX, max required pages) (while considering the required alignments) on driver load, by default U16_MAX is sufficient since the default RX rings value guarantees that we are in range, dynamically (on set_ringparam/set_channels) we will check if the new required UMR length (num mtts) is still in range, if not, fail the request.

2016-08-26dax: fix device-dax region baseDan Williams1-0/+3
The data offset for a dax region needs to account for a reservation in the resource range. Otherwise, device-dax is allowing mappings directly into the memmap or device-info-block area with crash signatures like the following: BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: get_zone_device_page+0x11/0x30 Call Trace: follow_devmap_pmd+0x298/0x2c0 follow_page_mask+0x275/0x530 __get_user_pages+0xe3/0x750 __gfn_to_pfn_memslot+0x1b2/0x450 [kvm] tdp_page_fault+0x130/0x280 [kvm] kvm_mmu_page_fault+0x5f/0xf0 [kvm] handle_ept_violation+0x94/0x180 [kvm_intel] vmx_handle_exit+0x1d3/0x1440 [kvm_intel] kvm_arch_vcpu_ioctl_run+0x81d/0x16a0 [kvm] kvm_vcpu_ioctl+0x33c/0x620 [kvm] do_vfs_ioctl+0xa2/0x5d0 SyS_ioctl+0x79/0x90 entry_SYSCALL_64_fastpath+0x1a/0xa4 Fixes: ab68f2622136 ("/dev/dax, pmem: direct access to persistent memory") Link: http://lkml.kernel.org/r/147205536732.1606.8994275381938837346.stgit@dwillia2-desk3.amr.corp.intel.com Signed-off-by: Dan Williams <dan.j.williams@intel.com> Reported-by: Abhilash Kumar Mulumudi <m.abhilash-kumar@hpe.com> Reported-by: Toshi Kani <toshi.kani@hpe.com> Tested-by: Toshi Kani <toshi.kani@hpe.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
