git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core and debugfs updates from Greg KH: "Here is the big set of driver core and debugfs updates for 6.14-rc1. Included in here is a bunch of driver core, PCI, OF, and platform rust bindings (all acked by the different subsystem maintainers), hence the merge conflict with the rust tree, and some driver core api updates to mark things as const, which will also require some fixups due to new stuff coming in through other trees in this merge window. There are also a bunch of debugfs updates from Al, and there is at least one user that does have a regression with these, but Al is working on tracking down the fix for it. In my use (and everyone else's linux-next use), it does not seem like a big issue at the moment. Here's a short list of the things in here: - driver core rust bindings for PCI, platform, OF, and some i/o functions. We are almost at the "write a real driver in rust" stage now, depending on what you want to do. - misc device rust bindings and a sample driver to show how to use them - debugfs cleanups in the fs as well as the users of the fs api for places where drivers got it wrong or were unnecessarily doing things in complex ways. - driver core const work, making more of the api take const * for different parameters to make the rust bindings easier overall. - other small fixes and updates All of these have been in linux-next with all of the aforementioned merge conflicts, and the one debugfs issue, which looks to be resolved "soon"" * tag 'driver-core-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (95 commits) rust: device: Use as_char_ptr() to avoid explicit cast rust: device: Replace CString with CStr in property_present() devcoredump: Constify 'struct bin_attribute' devcoredump: Define 'struct bin_attribute' through macro rust: device: Add property_present() saner replacement for debugfs_rename() orangefs-debugfs: don't mess with ->d_name octeontx2: don't mess with ->d_parent or ->d_parent->d_name arm_scmi: don't mess with ->d_parent->d_name slub: don't mess with ->d_name sof-client-ipc-flood-test: don't mess with ->d_name qat: don't mess with ->d_name xhci: don't mess with ->d_iname mtu3: don't mess wiht ->d_iname greybus/camera - stop messing with ->d_iname mediatek: stop messing with ->d_iname netdevsim: don't embed file_operations into your structs b43legacy: make use of debugfs_get_aux() b43: stop embedding struct file_operations into their objects carl9170: stop embedding file_operations into their objects ...

2025-01-16net: mvpp2: add EEE implementationRussell King (Oracle)
Add EEE support for mvpp2, using phylink's EEE implementation, which means we just need to implement the two methods for LPI control, and with the initial configuration. Only SGMII mode is supported, so only 100M and 1G speeds. Disabling LPI requires clearing a single bit. Enabling LPI needs a full configuration of several values, as the timer values are dependent on the MAC operating speed.

2025-01-16net: mvneta: convert to phylink EEE implementationRussell King (Oracle)
Convert mvneta to use phylink's EEE implementation by implementing the two LPI control methods, and adding the initial configuration and capabilities. Although disabling LPI requires clearing a single bit, for safety we clear the manual mode and force bits to ensure that auto mode will be used. Enabling LPI needs a full configuration of several values, as the timer values are dependent on the MAC operating speed, as per the original code. As Armada 388 states that EEE is only supported in "SGMII" modes, mark this in lpi_interfaces. Testing with RGMII on the Clearfog platform indicates that the receive path fails to detect LPI over RGMII.

2025-01-15net: protect NAPI enablement with netdev_lock()Jakub Kicinski
Wrap napi_enable() / napi_disable() with netdev_lock(). Provide the "already locked" flavor of the API. iavf needs the usual adjustment. A number of drivers call napi_enable() under a spin lock, so they have to be modified to take netdev_lock() first, then spin lock then call napi_enable_locked(). Protecting napi_enable() implies that napi->napi_id is protected by netdev_lock().

2025-01-15saner replacement for debugfs_rename()Al Viro
Existing primitive has several problems: 1) calling conventions are clumsy - it returns a dentry reference that is either identical to its second argument or is an ERR_PTR(-E...); in both cases no refcount changes happen. Inconvenient for users and bug-prone; it would be better to have it return 0 on success and -E... on failure. 2) it allows cross-directory moves; however, no such caller have ever materialized and considering the way debugfs is used, it's unlikely to happen in the future. What's more, any such caller would have fun issues to deal with wrt interplay with recursive removal. It also makes the calling conventions clumsier... 3) tautological rename fails; the callers have no race-free way to deal with that. 4) new name must have been formed by the caller; quite a few callers have it done by sprintf/kasprintf/etc., ending up with considerable boilerplate. Proposed replacement: int debugfs_change_name(dentry, fmt, ...). All callers convert to that easily, and it's simpler internally. IMO debugfs_rename() should go; if we ever get a real-world use case for cross-directory moves in debugfs, we can always look into the right way to handle that.

2024-11-26octeontx2-af: Quiesce traffic before NIX block resetHariprasad Kelam
During initialization, the AF driver resets all blocks. The RPM (MAC) block and NIX block operate on a credit-based model. When the NIX block resets during active traffic flow, it doesn't release credits to the RPM block. This causes the RPM FIFO to overflow, leading to receive traffic struck. To address this issue, the patch introduces the following changes: 1. Stop receiving traffic at the MAC level during AF driver initialization. 2. Perform an X2P reset (prevents RXFIFO of all LMACS from pushing data) 3. Reset the NIX block. 4. Clear the X2P reset and re-enable receiving traffic.

2024-11-26octeontx2-af: RPM: Fix low network performanceHariprasad Kelam
Low network performance is observed even on RPMs with larger FIFO lengths. The cn10kb silicon has three RPM blocks with the following FIFO sizes: -------------------- | RPM0 | 256KB | | RPM1 | 256KB | | RPM2 | 128KB | -------------------- The current design stores the FIFO length in a common structure for all RPMs (mac_ops). As a result, the FIFO length of the last RPM is applied to all RPMs, leading to reduced network performance. This patch resolved the problem by storing the fifo length in per MAC structure (cgx).

Hardware supports different types of MACs eg RPM, SDP, LBK. LBK is for internal Tx->Rx HW loopback path. RPM and SDP MACs support ingress/egress pkt IO on interfaces with different set of capabilities like interface modes. At the time of netdev driver registration PF will seek MAC related information from Admin function driver 'drivers/net/ethernet/marvell/octeontx2/af' and sets up ingress/egress queues etc such that pkt IO on the channels of these different MACs is possible.
