2019-09-04firmware: ti_sci: Allow for device shared and exclusive requestsLokesh Vutla
Sysfw provides an option for requesting exclusive access for a device using the flags MSG_FLAG_DEVICE_EXCLUSIVE. If this flag is not used, the device is meant to be shared across hosts. Once a device is requested from a host with this flag set, any request to this device from a different host will be nacked by sysfw. Current tisci driver enables this flag for every device requests. But this may not be true for all the devices. So provide a separate commands in driver for exclusive and shared device requests.

can_dev_rcv_lists This patch removes the old method of allocating the per device protocol specific memory via a netdevice_notifier. This had the drawback, that the allocation can fail, leading to a lot of null pointer checks in the code. This also makes the live cycle management of this memory quite complicated. This patch switches from the allocating the struct can_dev_rcv_lists in a NETDEV_REGISTER call to using the dev->ml_priv, which is allocated by the driver since the previous patch.

2019-09-04can: introduce CAN midlayer private and allocate it automaticallyMarc Kleine-Budde
This patch introduces the CAN midlayer private structure ("struct can_ml_priv") which should be used to hold protocol specific per device data structures. For now it's only member is "struct can_dev_rcv_lists". The CAN midlayer private is allocated via alloc_netdev()'s private and assigned to "struct net_device::ml_priv" during device creation. This is done transparently for CAN drivers using alloc_candev(). The slcan, vcan and vxcan drivers which are not using alloc_candev() have been adopted manually. The memory layout of the netdev_priv allocated via alloc_candev() will looke like this: +-------------------------+ | driver's priv | +-------------------------+ | struct can_ml_priv | +-------------------------+ | array of struct sk_buff | +-------------------------+ Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2019-09-01 (Software steering support) Abstract: -------- Mellanox ConnetX devices supports packet matching, packet modification and redirection. These functionalities are also referred to as flow-steering. To configure a steering rule, the rule is written to the device owned memory, this memory is accessed and cached by the device when processing a packet. Steering rules are constructed from multiple steering entries (STE). Rules are configured using the Firmware command interface. The Firmware processes the given driver command and translates them to STEs, then writes them to the device memory in the current steering tables. This process is slow due to the architecture of the command interface and the processing complexity of each rule. The highlight of this patchset is to cut the middle man (The firmware) and do steering rules programming into device directly from the driver, with no firmware intervention whatsoever. Motivation: ----------- Software (driver managed) steering allows for high rule insertion rates compared to the FW steering described above, this is achieved by using internal RDMA writes to the device owned memory instead of the slow command interface to program steering rules. Software (driver managed) steering, doesn't depend on new FW for new steering functionality, new implementations can be done in the driver skipping the FW layer. Performance: ------------ The insertion rate on a single core using the new approach allows programming ~300K rules per sec. (Done via direct raw test to the new mlx5 sw steering layer, without any kernel layer involved). Test: TC L2 rules 33K/s with Software steering (this patchset). 5K/s with FW and current driver. This will improve OVS based solution performance. Architecture and implementation details: ---------------------------------------- Software steering will be dynamically selected via devlink device parameter. Example: $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode pci/0000:06:00.0: name flow_steering_mode type driver-specific values: cmode runtime value smfs mlx5 software steering module a.k.a (DR - Direct Rule) is implemented and contained in mlx5/core/steering directory and controlled by MLX5_SW_STEERING kconfig flag. mlx5 core steering layer (fs_core) already provides a shim layer for implementing different steering mechanisms, software steering will leverage that as seen at the end of this series. When Software Steering for a specific steering domain (NIC/RDMA/Vport/ESwitch, etc ..) is supported, it will cause rules targeting this domain to be created using SW steering instead of FW. The implementation includes: Domain - The steering domain is the object that all other object resides in. It holds the memory allocator, send engine, locks and other shared data needed by lower objects such as table, matcher, rule, action. Each domain can contain multiple tables. Domain is equivalent to namespaces e.g (NIC/RDMA/Vport/ESwitch, etc ..) as implemented currently in mlx5_core fs_core (flow steering core). Table - Table objects are used for holding multiple matchers, each table has a level used to prevent processing loops. Packets are being directed to this table once it is set as the root table, this is done by fs_core using a FW command. A packet is being processed inside the table matcher by matcher until a successful hit, otherwise the packet will perform the default action. Matcher - Matchers objects are used to specify the fields mask for matching when processing a packet. A matcher belongs to a table, each matcher can hold multiple rules, each rule with different matching values corresponding to the matcher mask. Each matcher has a priority used for rule processing order inside the table. Action - Action objects are created to specify different steering actions such as count, reformat (encapsulate, decapsulate, ...), modify header, forward to table and many other actions. When creating a rule a sequence of actions can be provided to be executed on a successful match. Rule - Rule objects are used to specify a specific match on packets as well as the actions that should be executed. A rule belongs to a matcher. STE - This layer is used to hold the specific STE format for the device and to convert the requested rule to STEs. Each rule is constructed of an STE chain, Multiple rules construct a steering graph. Each node in the graph is a hash table containing multiple STEs. The index of each STE in the hash table is being calculated using a CRC32 hash function. Memory pool - Used for managing and caching device owned memory for rule insertion. The memory is being allocated using DM (device memory) API. Communication with device - layer for standard RDMA operation using RC QP to configure the device steering. Command utility - This module holds all of the FW commands that are required for SW steering to function. Patch planning and files: ------------------------- 1) First patch, adds the support to Add flow steering actions to fs_cmd shim layer. 2) Next 12 patch will add a file per each Software steering functionality/module as described above. (See patches with title: DR, *) 3) Add CONFIG_MLX5_SW_STEERING for software steering support and enable build with the new files 4) Next two patches will add the support for software steering in mlx5 steering shim layer net/mlx5: Add API to set the namespace steering mode net/mlx5: Add direct rule fs_cmd implementation 5) Last two patches will add the new devlink parameter to select mlx5 steering mode, will be valid only for switchdev mode for now. Two modes are supported: 1. DMFS - Device managed flow steering 2. SMFS - Software/Driver managed flow steering. In the DMFS mode, the HW steering entities are created through the FW. In the SMFS mode this entities are created though the driver directly. The driver will use the devlink steering mode only if the steering domain supports it, for now SMFS will manages only the switchdev eswitch steering domain. User command examples: - Set SMFS flow steering mode:: $ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime - Read device flow steering mode:: $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode pci/0000:06:00.0: name flow_steering_mode type driver-specific values: cmode runtime value smfs ==================== Signed-off-by: David S.

2019-09-03x86/amd_nb: Add PCI device IDs for family 17h, model 70hMarcel Bocu
The AMD Ryzen gen 3 processors came with a different PCI IDs for the function 3 & 4 which are used to access the SMN interface. The root PCI address however remained at the same address as the model 30h. Adding the F3/F4 PCI IDs respectively to the misc and link ids appear to be sufficient for k10temp, so let's add them and follow up on the patch if other functions need more tweaking. Vicki Pfau sent an identical patch after I checked that no-one had written this patch. I would have been happy about dropping my patch but unlike for his patch series, I had already Cc:ed the x86 people and they already reviewed the changes. Since Vicki has not answered to any email after his initial series, let's assume she is on vacation and let's avoid duplication of reviews from the maintainers and merge my series.

2019-09-03fs/namei.c: keep track of nd->root refcount statusAl Viro
The rules for nd->root are messy: * if we have LOOKUP_ROOT, it doesn't contribute to refcounts * if we have LOOKUP_RCU, it doesn't contribute to refcounts * if nd->root.mnt is NULL, it doesn't contribute to refcounts * otherwise it does contribute terminate_walk() needs to drop the references if they are contributing. So everything else should be careful not to confuse it, leading to rather convoluted code. It's easier to keep track of whether we'd grabbed the reference(s) explicitly. Use a new flag for that. Don't bother with zeroing nd->root.mnt on unlazy failures and in terminate_walk - it's not needed anymore (terminate_walk() won't care and the next path_init() will zero nd->root in !LOOKUP_ROOT case anyway). Resulting rules for nd->root refcounts are much simpler: they are contributing iff LOOKUP_ROOT_GRABBED is set in nd->flags. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2019-09-03iommu/vt-d: Remove global page flush supportJacob Pan
Global pages support is removed from VT-d spec 3.0. Since global pages G flag only affects first-level paging structures and because DMA request with PASID are only supported by VT-d spec. 3.0 and onward, we can safely remove global pages support. For kernel shared virtual address IOTLB invalidation, PASID granularity and page selective within PASID will be used. There is no global granularity supported. Without this fix, IOTLB invalidation will cause invalid descriptor error in the queued invalidation (QI) interface.

2019-09-03powercap: idle_inject: Use higher resolution for idle injectionDaniel Lezcano
The resolution of the idle injection is limited to 1ms. If there is a need for an injection of 1.2 ms, it is not possible. The idle injection API is not yet used, so it is safe to convert the existing API to the new time unit instead of adding more functions. Convert to microsecond in order to use a finer grain time unit when injecting idle cycles. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Rafael J.

The play_idle resolution is 1ms. The intel_powerclamp bases the idle duration on jiffies. The idle injection API is also using msec based duration but has no user yet. Unfortunately, msec based time does not fit well when we want to inject idle cycle precisely with shallow idle state. In order to set the scene for the incoming idle injection user, move the precision up to usec when calling play_idle.
