====================
tools/net/ynl: Add support for netlink-raw families
This patchset adds support for netlink-raw families such as rtnetlink.
Patch 1 fixes a typo in existing schemas
Patch 2 contains the schema definition
Patches 3 & 4 update the schema documentation
Patches 5 - 9 extends ynl
Patches 10 - 12 add several netlink-raw specs
The netlink-raw schema is very similar to genetlink-legacy and I thought
about making the changes there and symlinking to it. On balance I
thought that might be problematic for accurate schema validation.
rtnetlink doesn't seem to fit into unified or directional message
enumeration models. It seems like an 'explicit' model would be useful,
to force the schema author to specify the message ids directly.
There is not yet support for notifications because ynl currently doesn't
support defining 'event' properties on a 'do' operation. The message ids
are shared so ops need to be both sync and async. I plan to look at this
in a future patch.
The link and route messages contain different nested attributes
dependent on the type of link or route. Decoding these will need some
kind of attr-space selection that uses the value of another attribute as
the selector key. These nested attributes have been left with type
'binary' for now.

====================
{devlink,mlx5}: Add port function attributes for ipsec
From Dima:
Introduce hypervisor-level control knobs to set the functionality of PCI
VF devices passed through to guests. The administrator of a hypervisor
host may choose to change the settings of a port function from the
defaults configured by the device firmware.
The software stack has two types of IPsec offload - crypto and packet.
Specifically, the ip xfrm command has sub-commands for "state" and
"policy" that have an "offload" parameter. With ip xfrm state, both
crypto and packet offload types are supported, while ip xfrm policy can
only be offloaded in packet mode.
The series introduces two new boolean attributes of a port function:
ipsec_crypto and ipsec_packet. The goal is to provide a similar level of
granularity for controlling VF IPsec offload capabilities, which would
be aligned with the software model. This will allow users to decide if
they want both types of offload enabled for a VF, just one of them, or
none at all (which is the default).
At a high level, the difference between the two knobs is that with
ipsec_crypto, only XFRM state can be offloaded. Specifically, only the
crypto operation (Encrypt/Decrypt) is offloaded. With ipsec_packet, both
XFRM state and policy can be offloaded. Furthermore, in addition to
crypto operation offload, IPsec encapsulation is also offloaded. For
XFRM state, choosing between crypto and packet offload types is
possible. From the HW perspective, different resources may be required
for each offload type.
Examples of when a user prefers to enable IPsec packet offload for a VF
when using switchdev mode:
$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
function:
hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet disable
$ devlink port function set pci/0000:06:00.0/1 ipsec_packet enable
$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
function:
hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet enable
This enables the corresponding IPsec capability of the function before
it's enumerated, so when the driver reads the capability from the device
firmware, it is enabled. The driver is then able to configure
corresponding features and ops of the VF net device to support IPsec
state and policy offloading.

Implement devlink port function commands to enable / disable IPsec
packet offloads. This is used to control the IPsec capability of the
device.
When ipsec_offload is enabled for a VF, it prevents adding IPsec packet
offloads on the PF, because the two cannot be active simultaneously due
to HW constraints. Conversely, if there are any active IPsec packet
offloads on the PF, it's not allowed to enable ipsec_packet on a VF,
until PF IPsec offloads are cleared.

mlx5 HW can't perform IPsec offload operation simultaneously both on PF
and VFs at the same time. While the previous patches added devlink knobs
to change IPsec capabilities dynamically, there is a need to add a logic
to block such IPsec capabilities for the cases when IPsec is already
configured.

In the commit 366e46242b8e ("net/mlx5e: Make IPsec offload work together

Internally, that API used devlink lock to avoid races with userspace, but it is
not really needed as dev->priv.eswitch is stable and can't be changed. So remove
dependency on devlink lock and move block encap code back to its original place.

Expose port function commands to enable / disable IPsec packet offloads,
this is used to control the port IPsec capabilities.
When IPsec packet is disabled for a function of the port (default),
function cannot offload IPsec packet operations (encapsulation and XFRM
policy offload). When enabled, IPsec packet operations can be offloaded
by the function of the port, which includes crypto operation
(Encrypt/Decrypt), IPsec encapsulation and XFRM state and policy
offload.
Example of a PCI VF port which supports IPsec packet offloads:
$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0

Introduce IEP driver and packet timestamping support
This series introduces Industrial Ethernet Peripheral (IEP) driver to
support timestamping of ethernet packets and thus support PTP and PPS
for PRU ICSSG ethernet ports.
This series also adds 10M full duplex support for ICSSG ethernet driver.
There are two IEP instances. IEP0 is used for packet timestamping while IEP1
is used for 10M full duplex support.
This is v7 of the series [v1]. It addresses comments made on [v6].
This series is based on linux-next(#next-20230823).
Changes from v6 to v7:
*) Dropped blank line in example section of patch 1.
*) Patch 1 previously had three examples, removed two examples and kept only
one example as asked by Krzysztof.
*) Added Jacob Keller's RB tag in patch 5.
*) Dropped Roger's RB tags from the patches that he has authored (Patch 3 and 4)
Changes from v5 to v6:
*) Added description of IEP in commit messages of patch 2 as asked by Rob.
*) Described the items constraints properly for iep property in patch 2 as
asked by Rob.
*) Added Roger and Simon's RB tags.
Changes from v4 to v5:
*) Added comments on why we are using readl / writel instead of regmap_read()
/ write() in icss_iep_gettime() / settime() APIs as asked by Roger.
*) Added Conor's RB tag in patch 1 and 2.
Change from v3 to v4:
*) Changed compatible in iep dt bindings. Now each SoC has their own compatible
in the binding with "ti,am654-icss-iep" as a fallback as asked by Conor.
*) Addressed Andew's comments and removed helper APIs icss_iep_readl() /
writel(). Now the settime/gettime APIs directly use readl() / writel().
*) Moved selecting TI_ICSS_IEP in Kconfig from patch 3 to patch 4.
*) Removed forward declaration of icss_iep_of_match in patch 3.
*) Replaced use of of_device_get_match_data() to device_get_match_data() in
patch 3.
*) Removed of_match_ptr() from patch 3 as it is not needed.
Changes from v2 to v3:
*) Addressed Roger's comment and moved IEP1 related changes in patch 5.
*) Addressed Roger's comment and moved icss_iep.c / .h changes from patch 4
to patch 3.
*) Added support for multiple timestamping in patch 4 as asked by Roger.
*) Addressed Andrew's comment and added comment in case SPEED_10 in
icssg_config_ipg() API.
*) Kept compatible as "ti,am654-icss-iep" for all TI K3 SoCs
Changes from v1 to v2:
*) Addressed Simon's comment to fix reverse xmas tree declaration. Some APIs
in patch 3 and 4 were not following reverse xmas tree variable declaration.
Fixed it in this version.
*) Addressed Conor's comments and removed unsupported SoCs from compatible
comment in patch 1.
*) Addded patch 2 which was not part of v1. Patch 2, adds IEP node to dt
bindings for ICSSG.

For AM65x SR2.0 it's required to enable IEP1 in raw 64bit mode which is
used by PRU FW to monitor the link and apply w/a for 10M link issue.
Note. No public errata available yet.
Without this w/a the PRU FW will stuck if link state changes under TX
traffic pressure.
Hence, add support for 10M full duplex for AM65x SR2.0:
- add new IEP API to enable IEP, but without PTP support
- add pdata quirk_10m_link_issue to enable 10M link issue w/a.

- IEP1 is not used
- IEP0 is configured in shadow mode with 1ms cycle and shared between
Linux and FW. It provides time and TS in number cycles, so special
conversation in ns is required.
- IEP0 shared between PRUeth ports.
- IEP0 supports PPS, periodic output.
- IEP0 settime() and enabling PPS required FW interraction.
- RX TS provided with each packet in CPPI5 descriptor.
- TX TS returned through separate ICSSG hw queues for each port. TX TS
readiness is signaled by INTC IRQ. Only one packet at time can be requested
for TX TS.

Pull irq fix from Thomas Gleixner:
"A last minute fix for a regression introduced in the v6.5 merge
window.
The conversion of the software based interrupt resend mechanism to
hlist missed to add a check whether the descriptor is already enqueued
and dropped the interrupt descriptor lookup for nested interrupts.
The missing check whether the descriptor is already queued causes
hlist corruption and can be observed in the wild. The dropped parent
descriptor lookup has not yet caused problems, but it would result in
stale interrupt line in the worst case.
Add the missing enqueued check and bring the descriptor lookup back to
cure this"

The switch to using hlist for managing software resend of interrupts
broke resend in at least two ways:
First, unconditionally adding interrupt descriptors to the resend list can
corrupt the list when the descriptor in question has already been
added. This causes the resend tasklet to loop indefinitely with interrupts
disabled as was recently reported with the Lenovo ThinkPad X13s after
threaded NAPI was disabled in the ath11k WiFi driver.
This bug is easily fixed by restoring the old semantics of irq_sw_resend()
so that it can be called also for descriptors that have already been marked
for resend.
Second, the offending commit also broke software resend of nested
interrupts by simply discarding the code that made sure that such
interrupts are retriggered using the parent interrupt.
Add back the corresponding code that adds the parent descriptor to the
resend list.

In hw_breakpoint_control(), encode_ctrl_reg() has already encoded the
MWPnCFG3_LoadEn/MWPnCFG3_StoreEn bits in info->ctrl. We don't need to
add (1 << MWPnCFG3_LoadEn | 1 << MWPnCFG3_StoreEn) unconditionally.
Otherwise we can't set read watchpoint and write watchpoint separately.

This is a port of commit 379eb01c21795edb4c ("riscv: Ensure the value
of FP registers in the core dump file is up to date").
The values of FP/SIMD registers in the core dump file come from the
thread.fpu. However, kernel saves the FP/SIMD registers only before
scheduling out the process. If no process switch happens during the
exception handling, kernel will not have a chance to save the latest
values of FP/SIMD registers. So it may cause their values in the core
dump file incorrect. To solve this problem, force fpr_get()/simd_get()
to save the FP/SIMD registers into the thread.fpu if the target task
equals the current task.

Commit e6bcfdd75d53 ("x86/microcode: Hide the config knob") removed the
MICROCODE_AMD config, but left some references in defconfigs and comments,
that have no effect on any kernel build around.
Clean up those remaining config references. No functional change.
