This patch completes the transition of the ice driver to use the Page Pool
and libeth APIs, following the same direction as commit 5fa4caff59
("iavf: switch to Page Pool"). With the legacy page splitting and recycling
logic already removed, the driver is now in a clean state to adopt the
modern memory model.
The Page Pool integration simplifies buffer management by offloading
DMA mapping and recycling to the core infrastructure. This eliminates
the need for driver-specific handling of headroom, buffer sizing, and
page order. The libeth helper is used for CPU-side processing, while
DMA-for-device is handled by the Page Pool core.
Additionally, this patch extends the conversion to cover XDP support.
The driver now uses libeth_xdp helpers for Rx buffer processing,
and optimizes XDP_TX by skipping per-frame DMA mapping. Instead, all
buffers are mapped as bi-directional up front, leveraging Page Pool's
lifecycle management. This significantly reduces overhead in virtualized
environments.
Performance observations:
- In typical scenarios (netperf, XDP_PASS, XDP_DROP), performance remains
on par with the previous implementation.
- In XDP_TX mode:
* With IOMMU enabled, performance improves dramatically - over 5x
increase - due to reduced DMA mapping overhead and better memory reuse.
* With IOMMU disabled, performance remains comparable to the previous
implementation, with no significant changes observed.
- In XDP_DROP mode:
* For small MTUs, (where multiple buffers can be allocated on a single
memory page), a performance drop of approximately 20% is observed.
According to 'perf top' analysis, the bottleneck is caused by atomic
reference counter increments in the Page Pool.
* For normal MTUs, (where only one buffer can be allocated within a
single memory page), performance remains comparable to baseline
levels.
This change is also a step toward a more modular and unified XDP
implementation across Intel Ethernet drivers, aligning with ongoing
efforts to consolidate and streamline feature support.

The commit 53844673d5 ("iavf: kill 'legacy-rx' for good") removed
the legacy Rx path in the iavf driver. This change applies the same
rationale to the ice driver.
The legacy Rx path relied on manual skb allocation and header copying,
which has become increasingly inefficient and difficult to maintain.
With the stabilization of build_skb() and the growing adoption of
features like XDP, page_pool, and multi-buffer support, the legacy
approach is no longer viable.
Key drawbacks of the legacy path included:
- Higher memory pressure due to direct page allocations and splitting;
- Redundant memcpy() operations for packet headers;
- CPU overhead from eth_get_headlen() and Flow Dissector usage;
- Compatibility issues with XDP, which imposes strict headroom and
tailroom requirements.
The ice driver, like iavf, does not benefit from the minimal headroom
savings that legacy Rx once offered, as it already splits pages into
fixed halves. Removing this path simplifies the Rx logic, eliminates
unnecessary branches in the hotpath, and prepares the driver for
upcoming enhancements.
In addition to removing the legacy Rx path, this change also eliminates
the custom construct_skb() functions from both the standard and
zero-copy (ZC) Rx paths. These are replaced with the build_skb()
and standardized xdp_build_skb_from_zc() helpers, aligning the driver
with the modern XDP infrastructure and reducing code duplication.
This cleanup also reduces code complexity and improves maintainability
as we move toward a more unified and modern Rx model across drivers.

E830 supports Earliest TxTime First (ETF) hardware offload, which is
configured via the ETF Qdisc on a per-queue basis (see tc-etf(8)). ETF
introduces a new Tx flow mechanism that utilizes a timestamp ring
(tstamp_ring) alongside the standard Tx ring. This timestamp ring is
used to indicate when hardware will transmit a packet. Tx Time is
supported on the first 2048 Tx queues of the device, and the NVM image
limits the maximum number of Tx queues to 2048 for the device.
The allocation and initialization of the timestamp ring occur when the
feature is enabled on a specific Tx queue via tc-etf. The requested Tx
Time queue index cannot be greater than the number of Tx queues
(vsi->num_txq).
To support ETF, the following flags and bitmap are introduced:
- ICE_F_TXTIME: Device feature flag set for E830 NICs, indicating ETF
support.
- txtime_txqs: PF-level bitmap set when ETF is enabled and cleared
when disabled for a specific Tx queue. It is used by
ice_is_txtime_ena() to check if ETF is allocated and configured on
any Tx queue, which is checked during Tx ring allocation.
- ICE_TX_FLAGS_TXTIME: Per Tx ring flag set when ETF is allocated and
configured for a specific Tx queue. It determines ETF status during
packet transmission and is checked by ice_is_txtime_ena() to verify
if ETF is enabled on any Tx queue.
Due to a hardware issue that can result in a malicious driver detection
event, additional timestamp descriptors are required when wrapping
around the timestamp ring. Up to 64 additional timestamp descriptors
are reserved, reducing the available Tx descriptors.
To accommodate this, ICE_MAX_NUM_DESC_BY_MAC is introduced, defining:
- E830: Maximum Tx descriptor count of 8096 (8K - 32 - 64 for timestamp
fetch descriptors).
- E810 and E82X: Maximum Tx descriptor count of 8160 (8K - 32).

Recent versions of the E810 firmware have support for an extra interrupt to
handle report of the "low latency" Tx timestamps coming from the
specialized low latency firmware interface. Instead of polling the
registers, software can wait until the low latency interrupt is fired.
This logic makes use of the Tx timestamp tracking structure, ice_ptp_tx, as
it uses the same "ready" bitmap to track which Tx timestamps complete.
Unfortunately, the ice_ll_ts_intr() function does not check if the
tracker is initialized before its first access. This results in NULL
dereference or use-after-free bugs similar to the issues fixed in the
ice_ptp_ts_irq() function.
Fix this by only checking the in_use bitmap (and other fields) if the
tracker is marked as initialized. The reset flow will clear the init field
under lock before it tears the tracker down, thus preventing any
use-after-free or NULL access.

The ice_cfg_tx_topo function attempts to apply Tx scheduler topology
configuration based on NVM parameters, selecting either a 5 or 9 layer
topology.
As part of this flow, the driver acquires the "Global Configuration Lock",
which is a hardware resource associated with programming the DDP package
to the device. This "lock" is implemented by firmware as a way to
guarantee that only one PF can program the DDP for a device. Unlike a
traditional lock, once a PF has acquired this lock, no other PF will be
able to acquire it again (including that PF) until a CORER of the device.
Future requests to acquire the lock report that global configuration has
already completed.
The following flow is used to program the Tx topology:
* Read the DDP package for scheduler configuration data
* Acquire the global configuration lock
* Program Tx scheduler topology according to DDP package data
* Trigger a CORER which clears the global configuration lock
This is followed by the flow for programming the DDP package:
* Acquire the global configuration lock (again)
* Download the DDP package to the device
* Release the global configuration lock.
However, if configuration of the Tx topology fails, (i.e.
ice_get_set_tx_topo returns an error code), the driver exits
ice_cfg_tx_topo() immediately, and fails to trigger CORER.
While the global configuration lock is held, the firmware rejects most
AdminQ commands, as it is waiting for the DDP package download (or Tx
scheduler topology programming) to occur.
The current driver flows assume that the global configuration lock has been
reset by CORER after programming the Tx topology. Thus, the same PF
attempts to acquire the global lock again, and fails. This results in the
driver reporting "an unknown error occurred when loading the DDP package".
It then attempts to enter safe mode, but ultimately fails to finish
ice_probe() since nearly all AdminQ command report error codes, and the
driver stops loading the device at some point during its initialization.
The only currently known way that ice_get_set_tx_topo() can fail is with
certain older DDP packages which contain invalid topology configuration, on
firmware versions which strictly validate this data. The most recent
releases of the DDP have resolved the invalid data. However, it is still
poor practice to essentially brick the device, and prevent access to the
device even through safe mode or recovery mode. It is also plausible that
this command could fail for some other reason in the future.
We cannot simply release the global lock after a failed call to
ice_get_set_tx_topo(). Releasing the lock indicates to firmware that global
configuration (downloading of the DDP) has completed. Future attempts by
this or other PFs to load the DDP will fail with a report that the DDP
package has already been downloaded. Then, PFs will enter safe mode as they
realize that the package on the device does not meet the minimum version
requirement to load. The reported error messages are confusing, as they
indicate the version of the default "safe mode" package in the NVM, rather
than the version of the file loaded from /lib/firmware.
Instead, we need to trigger CORER to clear global configuration. This is
the lowest level of hardware reset which clears the global configuration
lock and related state. It also clears any already downloaded DDP.
Crucially, it does *not* clear the Tx scheduler topology configuration.
Refactor ice_cfg_tx_topo() to always trigger a CORER after acquiring the
global lock, regardless of success or failure of the topology
configuration.
We need to re-initialize the HW structure when we trigger the CORER. Thus,
it makes sense for this to be the responsibility of ice_cfg_tx_topo()
rather than its caller, ice_init_tx_topology(). This avoids needless
re-initialization in cases where we don't attempt to update the Tx
scheduler topology, such as if it has already been programmed.
There is one catch: failure to re-initialize the HW struct should stop
ice_probe(). If this function fails, we won't have a valid HW structure and
cannot ensure the device is functioning properly. To handle this, ensure
ice_cfg_tx_topo() returns a limited set of error codes. Set aside one
specifically, -ENODEV, to indicate that the ice_init_tx_topology() should
fail and stop probe.
Other error codes indicate failure to apply the Tx scheduler topology. This
is treated as a non-fatal error, with an informational message informing
the system administrator that the updated Tx topology did not apply. This
allows the device to load and function with the default Tx scheduler
topology, rather than failing to load entirely.
Note that this use of CORER will not result in loops with future PFs
attempting to also load the invalid Tx topology configuration. The first PF
will acquire the global configuration lock as part of programming the DDP.
Each PF after this will attempt to acquire the global lock as part of
programming the Tx topology, and will fail with the indication from
firmware that global configuration is already complete. Tx scheduler
topology configuration is only performed during driver init (probe or
devlink reload) and not during cleanup for a CORER that happens after probe
completes.

New timestamping API was introduced in commit 66f7223039 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6.
It is time to convert the Intel ice driver to the new API, so that
timestamping configuration can be removed from the ndo_eth_ioctl() path
completely.

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).

When the XDP program is loaded, the XDP callback adds new Tx queues.
This means that the callback must update the Tx scheduler with the new
queue number. In the event of a Tx scheduler failure, the XDP callback
should also fail and roll back any changes previously made for XDP
preparation.
The previous implementation had a bug that not all changes made by the
XDP callback were rolled back. This caused the crash with the following

Prepare for Intel IPU E2000 (GEN3)
This is the first part in introducing RDMA support for idpf.
----------------------------------------------------------------
Tatyana Nikolova says:
To align with review comments, the patch series introducing RDMA
RoCEv2 support for the Intel Infrastructure Processing Unit (IPU)
E2000 line of products is going to be submitted in three parts:
1. Modify ice to use specific and common IIDC definitions and
pass a core device info to irdma.
2. Add RDMA support to idpf and modify idpf to use specific and
common IIDC definitions and pass a core device info to irdma.
3. Add RDMA RoCEv2 support for the E2000 products, referred to as
GEN3 to irdma.
This first part is a 5 patch series based on the original
"iidc/ice/irdma: Update IDC to support multiple consumers" patch
to allow for multiple CORE PCI drivers, using the auxbus.
Patches:
1) Move header file to new name for clarity and replace ice
specific DSCP define with a kernel equivalent one in irdma
2) Unify naming convention
3) Separate header file into common and driver specific info
4) Replace ice specific DSCP define with a kernel equivalent
one in ice
5) Implement core device info struct and update drivers to use it

In preparation of supporting more than a single core PCI driver
for RDMA, move ice specific structs like qset_params, qos_info
and qos_params from iidc_rdma.h to iidc_rdma_ice.h.
Previously, the ice driver was just exporting its entire PF struct
to the auxiliary driver, but since each core driver will have its own
different PF struct, implement a universal struct that all core drivers
can provide to the auxiliary driver through the probe call.

tc clsact qdisc allows us to add offloaded egress rules with commands such
as the following one:
tc filter add dev <ifname> egress protocol lldp flower skip_sw action drop
Support the egress rule drop action when added to PF, with a few caveats:
* in switchdev mode, all PF traffic has to go uplink with an exception for
LLDP that can be delegated to a single VSI at a time
* in legacy mode, we cannot delegate LLDP functionality to another VSI, so
such packets from PF should not be blocked.
Also, simplify the rule direction logic, it was previously derived from
actions, but actually can be inherited from the tc block (and flipped in
case of port representors).

E830 supports raw receive and generic transmit checksum offloads.
Raw receive checksum support is provided by hardware calculating the
checksum over the whole packet, regardless of type. The calculated
checksum is provided to driver in the Rx flex descriptor. Then the driver
assigns the checksum to skb->csum and sets skb->ip_summed to
CHECKSUM_COMPLETE.
Generic transmit checksum support is provided by hardware calculating the
checksum given two offsets: the start offset to begin checksum calculation,
and the offset to insert the calculated checksum in the packet. Support is
advertised to the stack using NETIF_F_HW_CSUM feature.
E830 has the following limitations when both generic transmit checksum
offload and TCP Segmentation Offload (TSO) are enabled:
1. Inner packet header modification is not supported. This restriction
includes the inability to alter TCP flags, such as the push flag. As a
result, this limitation can impact the receiver's ability to coalesce
packets, potentially degrading network throughput.
2. The Maximum Segment Size (MSS) is limited to 1023 bytes, which prevents
support of Maximum Transmission Unit (MTU) greater than 1063 bytes.
Therefore NETIF_F_HW_CSUM and NETIF_F_ALL_TSO features are mutually
exclusive. NETIF_F_HW_CSUM hardware feature support is indicated but is not
enabled by default. Instead, IP checksums and NETIF_F_ALL_TSO are the
defaults. Enforcement of mutual exclusivity of NETIF_F_HW_CSUM and
NETIF_F_ALL_TSO is done in ice_set_features(). Mutual exclusivity
of IP checksums and NETIF_F_HW_CSUM is handled by netdev_fix_features().
When NETIF_F_HW_CSUM is requested the provided skb->csum_start and
skb->csum_offset are passed to hardware in the Tx context descriptor
generic checksum (GCS) parameters. Hardware calculates the 1's complement
from skb->csum_start to the end of the packet, and inserts the result in
the packet at skb->csum_offset.

Recovery Mode is intended to recover from a fatal failure scenario in
which the device is not accessible to the host, meaning the firmware is
non-responsive.
The purpose of the Firmware Recovery Mode is to enable software tools to
update firmware and/or device configuration so the fatal error can be
resolved.
Recovery Mode Firmware supports a limited set of admin commands required
for NVM update.
Recovery Firmware does not support hardware interrupts so a polling mode
is used.
The driver will expose only the minimum set of devlink commands required
for the recovery of the adapter.
Using an appropriate NVM image, the user can recover the adapter using
the devlink flash API.
Prior to 4.20 E810 Adapter Recovery Firmware supports only the update
and erase of the "fw.mgmt" component.
E810 Adapter Recovery Firmware doesn't support selected preservation of
cards settings or identifiers.
The following command can be used to recover the adapter:
$ devlink dev flash <pci-address> <update-image.bin> component fw.mgmt
overwrite settings overwrite identifier
Newer FW versions (4.20 or newer) supports update of "fw.undi" and
"fw.netlist" components.
$ devlink dev flash <pci-address> <update-image.bin>
