2017-08-25PCI/MSI: Don't warn when irq_create_affinity_masks() returns NULLChristoph Hellwig
irq_create_affinity_masks() can return NULL on non-SMP systems, when there are not enough "free" vectors available to spread, or if memory allocation for the CPU masks fails. Only the allocation failure is of interest, and even then the system will work just fine except for non-optimally spread vectors. Thus remove the warnings.

2017-08-25i40e: synchronize nvmupdate command and adminq subtaskSudheer Mogilappagari
During NVM update, state machine gets into unrecoverable state because i40e_clean_adminq_subtask can get scheduled after the admin queue command but before other state variables are updated. This causes incorrect input to i40e_nvmupd_check_wait_event and state transitions don't happen. This issue existed before but surfaced after commit 373149fc99a0 ("i40e: Decrease the scope of rtnl lock") This fix adds locking around admin queue command and update of state variables so that adminq_subtask will have accurate information whenever it gets scheduled.

2017-08-25i40e: prevent changing ITR if adaptive-rx/tx enabledAlan Brady
Currently the driver allows the user to change (or even disable) interrupt moderation if adaptive-rx/tx is enabled when this should not be the case. Adaptive RX/TX will not respect the user's ITR settings so allowing the user to change it is weird. This bug would also allow the user to disable interrupt moderation with adaptive-rx/tx enabled which doesn't make much sense either. This patch makes it such that if adaptive-rx/tx is enabled, the user cannot make any manual adjustments to interrupt moderation. It also makes it so that if ITR is disabled but adaptive-rx/tx is then enabled, ITR will be re-enabled.

2017-08-25i40e: move check for avoiding VID=0 filters into i40e_vsi_add_vlanJacob Keller
In i40e_vsi_add_vlan we treat attempting to add VID=0 as an error, because it does not do what the caller might expect. We already special case VID=0 in i40e_vlan_rx_add_vid so that we avoid this error when adding the VLAN. This special casing is necessary so that we do not add the VLAN=0 filter since we don't want to stop receiving untagged traffic. Unfortunately, not all callers of i40e_vsi_add_vlan are aware of this, including when we add VLANs from a VF device. Rather than special casing every single caller of i40e_vsi_add_vlan, lets just move this check internally. This makes the code simpler because the caller does not need to be aware of how VLAN=0 is special, and we don't forget to add this check in new places. This fixes a harmless error message displaying when adding a VLAN from within a VF. The message was meaningless but there is no reason to confuse end users and system administrators, and this is now avoided.

2017-08-25i40e/i40evf: use cmpxchg64 when updating private flags in ethtoolJacob Keller
When a user gives an invalid command to change a private flag which is not supported, either because it is read-only, or the device is not capable of the feature, we simply ignore the request. A naive solution would simply be to report error codes when one of the flags was not supported. However, this causes problems because it makes the operation not atomic. If a user requests multiple private flags together at once we could end up changing one before failing at the second flag. We can do a bit better if we instead update a temporary copy of the flags variable in the loop, and then copy it into place after. If we aren't careful this has the pitfall of potentially silently overwriting any changes caused by other threads. Avoid this by using cmpxchg64 which will compare and swap the flags variable only if it currently matched the old value. We'll report -EAGAIN in the (hopefully rare!) case where the cmpxchg64 fails. This ensures that we can properly report when flags are not supported in an atomic fashion without the risk of overwriting other threads changes.

2017-08-25i40e: remove workaround for Open Firmware MAC addressJacob Keller
Since commit b499ffb0a22c ("i40e: Look up MAC address in Open Firmware or IDPROM"), we've had support for obtaining the MAC address form Open Firmware or IDPROM. This code relied on sending the Open Firmware address directly to the device firmware instead of relying on our MAC/VLAN filter list. Thus, a work around was introduced in commit b1b15df59232 ("i40e: Explicitly write platform-specific mac address after PF reset") We refactored the Open Firmware address enablement code in the ill-named commit 41c4c2b50d52 ("i40e: allow look-up of MAC address from Open Firmware or IDPROM") Since this refactor, we no longer even set I40E_FLAG_PF_MAC. Further, we don't need this work around, because we actually store the MAC address as part of the MAC/VLAN filter hash. Thus, we will restore the address correctly upon reset. The refactor above failed to revert the workaround, so do that now.

2017-08-25i40e: separate hw_features from runtime changing flagsJacob Keller
The number of flags found in pf->flags has grown quite large, and there are a lot of different types of flags. Most of the flags are simply hardware features which are enabled on some firmware or some MAC types. Other flags are dynamic run-time flags which enable or disable certain features of the driver. Separate these two types of flags into pf->hw_features and pf->flags. The hw_features list will contain a set of features which are enabled at init time. This will not contain toggles or otherwise dynamically changing features. These flags should not need atomic protections, as they will be set once during init and then be essentially read only. Everything else will remain in the flags variable. These flags may be modified at any time during run time. A future patch may wish to convert these flags into set_bit/clear_bit/test_bit or similar approach to ensure atomic correctness. The I40E_FLAG_MFP_ENABLED flag may be a good fit for hw_features but currently is used by ethtool in the private flags settings, and thus has been left as part of flags. Additionally, I40E_FLAG_DCB_CAPABLE may be a good fit for the hw_features but this patch has not tried to untangle it yet.

2017-08-25i40evf: prevent VF close returning before state transitions to DOWNSudheer Mogilappagari
Currently i40evf_close() can return before state transitions to __I40EVF_DOWN because of the latency involved in processing and receiving response from PF driver and scheduling of VF watchdog_task. Due to this inconsistency an immediate call to i40evf_open() fails because state is still DOWN_PENDING. When a VF interface is in up state and we try to add it as slave, The bonding driver calls dev_close() and dev_open() in short duration resulting in dev_open returning error. The ifenslave command needs to be run again for dev_open to succeed. This fix ensures that watchdog timer is scheduled immediately after admin queue operations are scheduled in i40evf_down(). In addition a wait condition is added at the end of i40evf_close so that function wont return when state is still DOWN_PENDING. The timeout value is chosen after some profiling and includes some buffer.

2017-08-25xen-blkback: stop blkback thread of every queue in xen_blkif_disconnectAnnie Li
In xen_blkif_disconnect, before checking inflight I/O, following code stops the blkback thread, if (ring->xenblkd) { kthread_stop(ring->xenblkd); wake_up(&ring->shutdown_wq); } If there is inflight I/O in any non-last queue, blkback returns -EBUSY directly, and above code would not be called to stop thread of remaining queue and processs them. When removing vbd device with lots of disk I/O load, some queues with inflight I/O still have blkback thread running even though the corresponding vbd device or guest is gone. And this could cause some problems, for example, if the backend device type is file, some loop devices and blkback thread always lingers there forever after guest is destroyed, and this causes failure of umounting repositories unless rebooting the dom0. This patch allows thread of every queue has the chance to get stopped. Otherwise, only thread of queue previous to(including) first busy one get stopped, blkthread of remaining queue will still run. So stop all threads properly and return -EBUSY if any queue has inflight I/O.

Hence we can remove manipulation of the MXR_GRAPHIC_SXY(win) register and just zero them once in mixer_win_reset().

2017-08-25drm/exynos: mixer: simplify mixer_graph_buffer()Tobias Jakobi
DRM core already checks in drm_atomic_plane_check() if the pixelformat is valid. Hence we can collapse the default case of the switch statement with the XRGB8888 case. No functional change. Signed-off-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2017-08-25drm/exynos: mixer: simplify vp_video_buffer()Tobias Jakobi
DRM core already checks in drm_atomic_plane_check() if the pixelformat is valid. Hence we can drop the default case of the switch statement and collapse most of the code. Also rename the two booleans to reflect what true/false actually means, and to avoid mixing CrCb/NV21 descriptions. No functional change.
