Allow mana ethtool get_link_ksettings operation to report

Introduce support for net_shaper_ops in the MANA driver,
enabling configuration of rate limiting on the MANA NIC.
To apply rate limiting, the driver issues a HWC command via
mana_set_bw_clamp() and updates the corresponding shaper object
in the net_shaper cache. If an error occurs during this process,
the driver restores the previous speed by querying the current link
configuration using mana_query_link_cfg().
The minimum supported bandwidth is 100 Mbps, and only values that are
exact multiples of 100 Mbps are allowed. Any other values are rejected.
To remove a shaper, the driver resets the bandwidth to the maximum
supported by the SKU using mana_set_bw_clamp() and clears the
associated cache entry. If an error occurs during this process,
the shaper details are retained.
On the hardware that does not support these APIs, the net-shaper
calls to set speed would fail.
Set the speed:
./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/net_shaper.yaml \
--do set --json '{"ifindex":'$IFINDEX',
"handle":{"scope": "netdev", "id":'$ID' },
"bw-max": 200000000 }'

As auxiliary clocks do not utilize the offset fields of the core time

Now that we stash persistent information in struct pid there's no need
to play volatile games with pinning struct pid via dentries in pidfs.

Persist exit and coredump information independent of whether anyone
currently holds a pidfd for the struct pid.
The current scheme allocated pidfs dentries on-demand repeatedly.
This scheme is reaching it's limits as it makes it impossible to pin
information that needs to be available after the task has exited or
coredumped and that should not be lost simply because the pidfd got
closed temporarily. The next opener should still see the stashed
information.
This is also a prerequisite for supporting extended attributes on
pidfds to allow attaching meta information to them.
If someone opens a pidfd for a struct pid a pidfs dentry is allocated
and stashed in pid->stashed. Once the last pidfd for the struct pid is
closed the pidfs dentry is released and removed from pid->stashed.
So if 10 callers create a pidfs dentry for the same struct pid
sequentially, i.e., each closing the pidfd before the other creates a
new one then a new pidfs dentry is allocated every time.
Because multiple tasks acquiring and releasing a pidfd for the same
struct pid can race with each another a task may still find a valid
pidfs entry from the previous task in pid->stashed and reuse it. Or it
might find a dead dentry in there and fail to reuse it and so stashes a
new pidfs dentry. Multiple tasks may race to stash a new pidfs dentry
but only one will succeed, the other ones will put their dentry.
The current scheme aims to ensure that a pidfs dentry for a struct pid
can only be created if the task is still alive or if a pidfs dentry
already existed before the task was reaped and so exit information has
been was stashed in the pidfs inode.
That's great except that it's buggy. If a pidfs dentry is stashed in
pid->stashed after pidfs_exit() but before __unhash_process() is called
we will return a pidfd for a reaped task without exit information being
available.
The pidfds_pid_valid() check does not guard against this race as it
doens't sync at all with pidfs_exit(). The pid_has_task() check might be
successful simply because we're before __unhash_process() but after
pidfs_exit().
Introduce a new scheme where the lifetime of information associated with
a pidfs entry (coredump and exit information) isn't bound to the
lifetime of the pidfs inode but the struct pid itself.
The first time a pidfs dentry is allocated for a struct pid a struct
pidfs_attr will be allocated which will be used to store exit and
coredump information.
If all pidfs for the pidfs dentry are closed the dentry and inode can be
cleaned up but the struct pidfs_attr will stick until the struct pid
itself is freed. This will ensure minimal memory usage while persisting
relevant information.
The new scheme has various advantages. First, it allows to close the
race where we end up handing out a pidfd for a reaped task for which no
exit information is available. Second, it minimizes memory usage.
Third, it allows to remove complex lifetime tracking via dentries when
registering a struct pid with pidfs. There's no need to get or put a
reference. Instead, the lifetime of exit and coredump information
associated with a struct pid is bound to the lifetime of struct pid
itself.

As long as there is only a single timekeeper, there is no need to clarify
which timekeeper is used. But with the upcoming reusage of the timekeeper
infrastructure for auxiliary clock timekeepers, an ID is required to

Introduce an enum for timekeeper IDs, introduce a field in struct tk_data
to store this timekeeper id and add also initialization. The id struct
field is added at the end of the second cachline, as there is a 4 byte hole

The firmware will be able to only save and restore the context related to
library management.
This means that even without a full context save, the libraries do not
need to be re-loaded to the firmware after second or consecutive boots.
This is reported via the FW_READY notification, where BIT(15) indicates:
0 - the library restore is not done
1 - library restore is done
This bit is only valid if full context save is not enabled, full context
save is by definition saves and restores the library related book-keeping
as well.
Add a new flag to tell the platform code if the libraries have been
restored, no need to reload them after boot.

This patch introduces the ability to configure the PSE PI budget evaluation
strategies. Budget evaluation strategies is utilized by PSE controllers to
determine which ports to turn off first in scenarios such as power budget
exceedance.
The pis_prio_max value is used to define the maximum priority level
supported by the controller. Both the current priority and the maximum
priority are exposed to the user through the pse_ethtool_get_status call.
This patch add support for two mode of budget evaluation strategies.
1. Static Method:
This method involves distributing power based on PD classification.
It’s straightforward and stable, the PSE core keeping track of the
budget and subtracting the power requested by each PD’s class.
Advantages: Every PD gets its promised power at any time, which
guarantees reliability.
Disadvantages: PD classification steps are large, meaning devices
request much more power than they actually need. As a result, the power
supply may only operate at, say, 50% capacity, which is inefficient and
wastes money.
Priority max value is matching the number of PSE PIs within the PSE.
2. Dynamic Method:
To address the inefficiencies of the static method, vendors like
Microchip have introduced dynamic power budgeting, as seen in the
PD692x0 firmware. This method monitors the current consumption per port
and subtracts it from the available power budget. When the budget is
exceeded, lower-priority ports are shut down.
Advantages: This method optimizes resource utilization, saving costs.
Disadvantages: Low-priority devices may experience instability.
Priority max value is set by the PSE controller driver.
For now, budget evaluation methods are not configurable and cannot be
mixed. They are hardcoded in the PSE driver itself, as no current PSE
controller supports both methods.

Introduce PSE power domain support as groundwork for upcoming port
priority features. Multiple PSE PIs can now be grouped under a single
PSE power domain, enabling future enhancements like defining available
power budgets, port priority modes, and disconnection policies. This
setup will allow the system to assess whether activating a port would
exceed the available power budget, preventing over-budget states
proactively.

Add support for devm_pse_irq_helper() to register PSE interrupts and report
events such as over-current or over-temperature conditions. This follows a
similar approach to the regulator API but also sends notifications using a
dedicated PSE ethtool netlink socket.

In preparation for reporting PSE events via ethtool notifications,
introduce an attached_phydev field in the pse_control structure.
This field stores the phy_device associated with the PSE PI,
ensuring that notifications are sent to the correct network
interface.
The attached_phydev pointer is directly tied to the PHY lifecycle. It
is set when the PHY is registered and cleared when the PHY is removed.
There is no need to use a refcount, as doing so could interfere with
the PHY removal process.

Drivers that are using ops lock and don't depend on RTNL lock
still need to manage it because udp_tunnel's RTNL dependency.
Introduce new udp_tunnel_nic_lock and use it instead of
rtnl_lock. Drop non-UDP_TUNNEL_NIC_INFO_MAY_SLEEP mode from
udp_tunnel infra (udp_tunnel_nic_device_sync_work needs to
grab udp_tunnel_nic_lock mutex and might sleep).
Cover more places in v4:
- netlink
- udp_tunnel_notify_add_rx_port (ndo_open)
- triggers udp_tunnel_nic_device_sync_work
- udp_tunnel_notify_del_rx_port (ndo_stop)
- triggers udp_tunnel_nic_device_sync_work
- udp_tunnel_get_rx_info (__netdev_update_features)
- triggers NETDEV_UDP_TUNNEL_PUSH_INFO
- udp_tunnel_drop_rx_info (__netdev_update_features)
- triggers NETDEV_UDP_TUNNEL_DROP_INFO
- udp_tunnel_nic_reset_ntf (ndo_open)
- notifiers
- udp_tunnel_nic_netdevice_event, depending on the event:
- triggers NETDEV_UDP_TUNNEL_PUSH_INFO
- triggers NETDEV_UDP_TUNNEL_DROP_INFO
- ethnl_tunnel_info_reply_size
- udp_tunnel_nic_set_port_priv (two intel drivers)

Merge the IPQ5424 CMN PLL binding through a topic branch, to allow the
newly introduced clock constants to be made available to the DeviceTree
branch as well.
|
|
The CMN PLL block in the IPQ5424 SoC takes 48 MHZ as the reference
input clock. The output clocks are the same as IPQ9574 SoC, except
for the clock rate of output clocks to PPE and NSS.
Also, add the new header file to export the CMN PLL output clock
specifiers for IPQ5424 SoC.

Commit under fixes switched to uAPI generation from the YAML
spec. A number of custom defines were left behind, mostly
for commands very hard to express in YAML spec.
Among what was left behind was the name and version of
the generic netlink family. Problem is that the codegen
always outputs those values so we ended up with a duplicated,
differently named set of defines.
Provide naming info in YAML and remove the incorrect defines.
Fixes: 8d0580c6ebdd ("ethtool: regenerate uapi header from the spec")

- Use correct DMI BIOS build date for ThinkPad W541 quirk (me)
- Disallow LPM for ASUSPRO-D840SA motherboard as this board
interestingly enough gets graphical corruptions on the iGPU when LPM
is enabled (me)
- Disallow LPM for Asus B550-F motherboard as this board will get
command timeouts on ports 5 and 6, yet LPM with the same drive works
fine on all other ports (Mikko)

Pin controller core code only stores the pointer to
'struct pinctrl_desc' and does not modify it anywhere. The pointer can
be changed to pointer to const which makes the code safer, explicit and
later allows constifying 'pinctrl_desc' allocations in individual
drivers.
