2024-09-11RDMA/mlx5: Split ODP mkey search logicMichael Guralnik
Split the search for the ODP mkey when handling an rdma type page fault to a helper function, later to be used in other page fault types.

2024-09-11RDMA/mlx5: Enforce umem boundaries for explicit ODP page faultsMichael Guralnik
The new memory scheme page faults are requesting the driver to fetch additinal pages to the faulted memory access. This is done in order to prefetch pages before and after the area that got the page fault, assuming this will reduce the total amount of page faults. The driver should ensure it handles only the pages that are within the umem range.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all can drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

for non-continous port maps" This reverts commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 because it breaks codecs using non-continuous masks in source and sink ports. The commit missed the point that port numbers are not used as indices for iterating over prop.sink_ports or prop.source_ports. Soundwire core and existing codecs expect that the array passed as prop.sink_ports and prop.source_ports is continuous. The port mask still might be non-continuous, but that's unrelated.

This resolves a warning from get_maintainers.pl about no files matching the outdated directory. - Constify struct exynos_drm_ipp_funcs By making struct exynos_drm_ipp_funcs constant, the patch enhances security by moving the structure to a read-only section of memory. This change results in a slight reduction in the data section size. - Remove unnecessary code The function exynos_atomic_commit is removed as it became redundant after a previous update.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2024-08-29 HW-Managed Flow Steering in mlx5 driver Yevgeny Kliteynik says: ======================= 1. Overview ----------- ConnectX devices support packet matching, modification, and redirection. This functionality is referred 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. The first implementation of Flow Steering was done in FW, and it is referred in the mlx5 driver as Device-Managed Flow Steering (DMFS). Later we introduced SW-managed Flow Steering (SWS or SMFS), where the driver is writing directly to the device's configuration memory (ICM) through RC QP using RDMA operations (RDMA-read and RDAM-write), thus achieving higher rates of rule insertion/deletion. Now we introduce a new flow steering implementation: HW-Managed Flow Steering (HWS or HMFS). In this new approach, the driver is configuring steering rules directly to the HW using the WQs with a special new type of WQE. This way we can reach higher rule insertion/deletion rate with much lower CPU utilization compared to SWS. The key benefits of HWS as opposed to SWS: + HW manages the steering decision tree - HW calculates CRC for each entry - HW handles tree hash collisions - HW & FW manage objects refcount + HW keeps cache coherency: - HW provides tree access locking and synchronization - HW provides notification on completion + Insertion rate isn’t affected by background traffic - Dedicated HW components that handle insertion 2. Performance -------------- Measuring Connection Tracking with simple IPv4 flows w/o NAT, we are able to get ~5 times more flows offloaded per second using HWS. 3. Configuration ---------------- The enablement of HWS mode in eswitch manager is done using the same devlink param that is already used for switching between FW-managed steering and SW-managed steering modes: # devlink dev param set pci/<PCI_ID> name flow_steering_mode cmod runtime value hmfs 4. Upstream Submission ---------------------- HWS support consists of 3 main components: + Steering: - The lower layer that exposes HWS API to upper layers and implements all the management of flow steering building blocks + FS-Core - Implementation of fs_hws layer to enable fs_core to use HWS instead of FW or SW steering - Create HW steering action pools to utilize the ability of HWS to share steering actions among different rules - Add support for configuring HWS mode through devlink command, similar to configuring SWS mode + Connection Tracking - Implementation of CT support for HW steering - Hooks up the CT ops for the new steering mode and uses the HWS API to implement connection tracking. Because of the large number of patches, we need to perform the submission in several separate patch series. This series is the first submission that lays the ground work for the next submissions, where an actual user of HWS will be added. 5. Patches in this series ------------------------- This patch series contains implementation of the first bullet from above. ======================= * tag 'mlx5-updates-2024-09-02' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: HWS, added API and enabled HWS support net/mlx5: HWS, added send engine and context handling net/mlx5: HWS, added debug dump and internal headers net/mlx5: HWS, added backward-compatible API handling net/mlx5: HWS, added memory management handling net/mlx5: HWS, added vport handling net/mlx5: HWS, added modify header pattern and args handling net/mlx5: HWS, added FW commands handling net/mlx5: HWS, added matchers functionality net/mlx5: HWS, added definers handling net/mlx5: HWS, added rules handling net/mlx5: HWS, added tables handling net/mlx5: HWS, added actions handling net/mlx5: Added missing definitions in preparation for HW Steering net/mlx5: Added missing mlx5_ifc definition for HW Steering ==================== Link: https://patch.msgid.link/20240909181250.41596-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The name field of struct bnxt_irq is written using snprintf in bnxt_setup_msix(). Make the field large enough to fit the maximal formatted string to prevent truncation. Truncated IRQ names are less meaningful to the user. For example, "enp4s0f0np0-TxRx-0" gets truncated to "enp4s0f0np0-TxRx-" with the existing code. Make sure we have space for the extra characters added to the IRQ names: - the characters introduced by the static format string: hyphens - the maximal static substituted ring type string: "TxRx" - the maximum length of an integer formatted as a string, even though reasonable ring numbers would never be as long as this.

2024-09-10bnxt_en: Add MSIX check in bnxt_check_rings()Michael Chan
bnxt_check_rings() is called to ensure that we have the hardware ring resources before committing to reinitialize with the new number of rings. MSIX vectors are never checked at this point, because up until recently we must first disable MSIX before we can allocate the new set of MSIX vectors. Now that we support dynamic MSIX allocation, check to make sure we can dynamically allocate the new MSIX vectors as the last step in bnxt_check_rings() if dynamic MSIX is supported. For example, the IOMMU group may limit the number of MSIX vectors for the device. With this patch, the ring change will fail more gracefully when there is not enough MSIX vectors. It is also better to move bnxt_check_rings() to be called as the last step when changing ethtool rings.

2024-09-10PCI: Rename CRS Completion Status to RRSBjorn Helgaas
PCIe r6.0 changed the abbreviation for "Configuration Request Retry Status" Completion Status from "CRS" to "RRS" and uses the terminology of "Configuration RRS Software Visibility" instead of "CRS Software Visibility". Align the Linux usage with the r6.0 spec language. No functional change intended. It's confusing to make this change, but I think "RRS" *is* a better abbreviation because it was easy to interpret "CRS" as "Completion Retry Status", which really didn't make any sense.

2024-09-10PCI: aardvark: Correct Configuration RRS checkingBjorn Helgaas
Per PCIe r6.0, sec 2.3.2, when a Root Complex handles a Completion with Request Retry Status for a Configuration Read Request that includes both bytes of the Vendor ID field, it must complete the Request to the host by returning 0001h for the Vendor ID and all 1's for any additional bytes. Previously we only returned the 0001h Vendor ID value if we got an RRS completion for reads of exactly 4 bytes. A read of 2 bytes would not qualify, although the spec says it should. Check for reads of 2 or more bytes including the Vendor ID. I don't think this will fix any observable problems because RRS only applies to the first config reads after reset, and those are all currently dword (4-byte) reads.

2024-09-10PCI: Wait for device readiness with Configuration RRSBjorn Helgaas
After a device reset, delays are required before the device can successfully complete config accesses. PCIe r6.0, sec 6.6, specifies some delays required before software can perform config accesses. Devices that require more time after those delays may respond to config accesses with Configuration Request Retry Status (RRS) completions. Callers of pci_dev_wait() are responsible for delays until the device can respond to config accesses. pci_dev_wait() waits any additional time until the device can successfully complete config accesses. Reading config space of devices that are not present or not ready typically returns ~0 (PCI_ERROR_RESPONSE). Previously we polled the Command register until we got a value other than ~0. This is sometimes a problem because Root Complex handling of RRS completions may include several retries and implementation-specific behavior that is invisible to software (see sec 2.3.2), so the exponential backoff in pci_dev_wait() may not work as intended. Linux enables Configuration RRS Software Visibility on all Root Ports that support it. If it is enabled, read the Vendor ID instead of the Command register. RRS completions cause immediate return of the 0x0001 reserved Vendor ID value, so the pci_dev_wait() backoff works correctly. When a read of Vendor ID eventually completes successfully by returning a non-0x0001 value (the Vendor ID or 0xffff for VFs), the device should be initialized and ready to respond to config requests. For conventional PCI devices or devices below Root Ports that don't support Configuration RRS Software Visibility, poll the Command register as before. This was developed independently, but is very similar to Stanislav Spassov's previous work at https://lore.kernel.org/linux-pci/20200223122057.6504-1-stanspas@amazon.com Link: https://lore.kernel.org/r/20240827234848.4429-2-helgaas@kernel.org Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Tested-by: Duc Dang <ducdang@google.com>
