As part of switchdev environment setup, uplink VSI is configured as
default for both Tx and Rx. Default Rx VSI is also used by promiscuous
mode. If promisc mode is enabled and an attempt to enter switchdev mode
is made, the setup will fail because Rx VSI is already configured as
default (rule exists).
Reproducer:
devlink dev eswitch set $PF1_PCI mode switchdev
ip l s $PF1 up
ip l s $PF1 promisc on
echo 1 > /sys/class/net/$PF1/device/sriov_numvfs
In switchdev setup, use ice_set_dflt_vsi() instead of plain
ice_cfg_dflt_vsi(), which avoids repeating setting default VSI for Rx if
it's already configured.

The fix is mostly about reverting what was done in commit 1dc1a7e7f4
("ice: Centrallize Rx buffer recycling") followed by proper timing on
page_count() storage and then removing the ice_rx_buf::act related logic
(which was mostly introduced for purposes from cited commit).
Special thanks to Xu Du for providing reproducer and Jacob Keller for
initial extensive analysis.

Idea behind having ice_rx_buf::act was to simplify and speed up the Rx
data path by walking through buffers that were representing cleaned HW
Rx descriptors. Since it caused us a major headache recently and we
rolled back to old approach that 'puts' Rx buffers right after running
XDP prog/creating skb, this is useless now and should be removed.
Get rid of ice_rx_buf::act and related logic. We still need to take care
of a corner case where XDP program releases a particular fragment.
Make ice_run_xdp() to return its result and use it within
ice_put_rx_mbuf().

If we store the pgcnt on few fragments while being in the middle of
gathering the whole frame and we stumbled upon DD bit not being set, we
terminate the NAPI Rx processing loop and come back later on. Then on
next NAPI execution we work on previously stored pgcnt.
Imagine that second half of page was used actively by networking stack
and by the time we came back, stack is not busy with this page anymore
and decremented the refcnt. The page reuse algorithm in this case should
be good to reuse the page but given the old refcnt it will not do so and
attempt to release the page via page_frag_cache_drain() with
pagecnt_bias used as an arg. This in turn will result in negative refcnt
on struct page, which was initially observed by Xu Du.
Therefore, move the page count storage from ice_get_rx_buf() to a place
where we are sure that whole frame has been collected, but before
calling XDP program as it internally can also change the page count of
fragments belonging to xdp_buff.

Introduce a new helper ice_put_rx_mbuf() that will go through gathered
frags from current frame and will call ice_put_rx_buf() on them. Current
logic that was supposed to simplify and optimize the driver where we go
through a batch of all buffers processed in current NAPI instance turned
out to be broken for jumbo frames and very heavy load that was coming
from both multi-thread iperf and nginx/wrk pair between server and
client. The delay introduced by approach that we are dropping is simply
too big and we need to take the decision regarding page
recycling/releasing as quick as we can.
While at it, address an error path of ice_add_xdp_frag() - we were
missing buffer putting from day 1 there.
As a nice side effect we get rid of annoying and repetitive three-liner:
xdp->data = NULL;
rx_ring->first_desc = ntc;
rx_ring->nr_frags = 0;
by embedding it within introduced routine.

Fix &ice_parser_rt::bst_key size. It was wrongly set to 10 instead of 20
in the initial impl commit (see Fixes tag). All usage code assumed it was
of size 20. That was also the initial size present up to v2 of the intro
series [2], but halved by v3 [3] refactor described as "Replace magic
hardcoded values with macros." The introducing series was so big that
some ugliness was unnoticed, same for bugs :/
ICE_BST_KEY_TCAM_SIZE and ICE_BST_TCAM_KEY_SIZE were differing by one.
There was tmp variable @j in the scope of edited function, but was not
used in all places. This ugliness is now gone.
I'm moving ice_parser_rt::pg_prio a few positions up, to fill up one of
the holes in order to compensate for the added 10 bytes to the ::bst_key,
resulting in the same size of the whole as prior to the fix, and minimal
changes in the offsets of the fields.
Extend also the debug dump print of the key to cover all bytes. To not
have string with 20 "%02x" and 20 params, switch to
ice_debug_array_w_prefix().
This fix obsoletes Ahmed's attempt at [1].

separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec,
to ease maintenance and future development.

1) Per-CPU kthreads must stay affine to a single CPU and never execute
relevant code on any other CPU. This is currently handled by smpboot
code which takes care of CPU-hotplug operations. Affinity here is
a correctness constraint.
2) Some kthreads _have_ to be affine to a specific set of CPUs and can't
run anywhere else. The affinity is set through kthread_bind_mask()
and the subsystem takes care by itself to handle CPU-hotplug
operations. Affinity here is assumed to be a correctness constraint.
3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This
is not a correctness constraint but merely a preference in terms of
memory locality. kswapd and kcompactd both fall into this category.
The affinity is set manually like for any other task and CPU-hotplug
is supposed to be handled by the relevant subsystem so that the task
is properly reaffined whenever a given CPU from the node comes up.
Also care should be taken so that the node affinity doesn't cross
isolated (nohz_full) cpumask boundaries.
4) Similar to the previous point except kthreads have a _preferred_
affinity different than a node. Both RCU boost kthreads and RCU
exp kworkers fall into this category as they refer to "RCU nodes"
from a distinctly distributed tree.
Currently the preferred affinity patterns (3 and 4) have at least 4
identified users, with more or less success when it comes to handle
CPU-hotplug operations and CPU isolation. Each of which do it in its own
ad-hoc way.
This is an infrastructure proposal to handle this with the following API
changes:
_ kthread_create_on_node() automatically affines the created kthread to
its target node unless it has been set as per-cpu or bound with
kthread_bind[_mask]() before the first wake-up.
- kthread_affine_preferred() is a new function that can be called right
after kthread_create_on_node() to specify a preferred affinity
different than the specified node.
When the preferred affinity can't be applied because the possible
targets are offline or isolated (nohz_full), the kthread is affine
to the housekeeping CPUs (which means to all online CPUs most of the
time or only the non-nohz_full CPUs when nohz_full= is set).
kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
converted, along with a few old drivers.
Summary of the changes:
* Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu()
* Introduce task_cpu_fallback_mask() that defines the default last
resort affinity of a task to become nohz_full aware
* Add some correctness check to ensure kthread_bind() is always called
before the first kthread wake up.
* Default affine kthread to its preferred node.
* Convert kswapd / kcompactd and remove their halfway working ad-hoc

* Implement kthreads preferred affinity
* Unify kthread worker and kthread API's style

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>

HW can have different input/output delays for each of the pins.
Currently, only E82X adapters have delay compensation based on TSPLL
config and E810 adapters have constant 1 ms compensation, both cases
only for output delays and the same one for all pins.
E825 adapters have different delays for SDP and other pins. Those
delays are also based on direction and input delays are different than
output ones. This is the main reason for moving delays to pin
description structure.
Add a field in ice_ptp_pin_desc structure to reflect that. Delay values
are based on approximate calculations of HW delays based on HW spec.
Implement external timestamp (input) delay compensation.
Remove existing definitions and wrappers for periodic output propagation
delays.

Programming the PHY registers in preparation for an increment value change
or a timer adjustment on E810 requires issuing Admin Queue commands for
each PHY register. It has been found that the firmware Admin Queue
processing occasionally has delays of tens or rarely up to hundreds of
milliseconds. This delay cascades to failures in the PTP applications which
depend on these updates being low latency.
Consider a standard PTP profile with a sync rate of 16 times per second.
This means there is ~62 milliseconds between sync messages. A complete
cycle of the PTP algorithm
1) Sync message (with Tx timestamp) from source
2) Follow-up message from source
3) Delay request (with Tx timestamp) from sink
4) Delay response (with Rx timestamp of request) from source
5) measure instantaneous clock offset
6) request time adjustment via CLOCK_ADJTIME systemcall
The Tx timestamps have a default maximum timeout of 10 milliseconds. If we
assume that the maximum possible time is used, this leaves us with ~42
milliseconds of processing time for a complete cycle.
The CLOCK_ADJTIME system call is synchronous and will block until the
driver completes its timer adjustment or frequency change.
If the writes to prepare the PHY timers get hit by a latency spike of 50
milliseconds, then the PTP application will be delayed past the point where
the next cycle should start. Packets from the next cycle may have already
arrived and are waiting on the socket.
In particular, LinuxPTP ptp4l may start complaining about missing an
announce message from the source, triggering a fault. In addition, the
clockcheck logic it uses may trigger. This clockcheck failure occurs
because the timestamp captured by hardware is compared against a reading of
CLOCK_MONOTONIC. It is assumed that the time when the Rx timestamp is
captured and the read from CLOCK_MONOTONIC are relatively close together.
This is not the case if there is a significant delay to processing the Rx
packet.
Newer firmware supports programming the PHY registers over a low latency
interface which bypasses the Admin Queue. Instead, software writes to the
REG_LL_PROXY_L and REG_LL_PROXY_H registers. Firmware reads these registers
and then programs the PHY timers.
Implement functions to use this interface when available to program the PHY
timers instead of using the Admin Queue. This avoids the Admin Queue
latency and ensures that adjustments happen within acceptable latency
bounds.

Newer firmware for the E810 devices support a 'low latency' interface to
interact with the PHY without using the Admin Queue. This is interacted
with via the REG_LL_PROXY_L and REG_LL_PROXY_H registers.
Currently, this interface is only used for Tx timestamps. There are two
different mechanisms, including one which uses an interrupt for firmware to
signal completion. However, these two methods are mutually exclusive, so no
synchronization between them was necessary.
This low latency interface is being extended in future firmware to support
also programming the PHY timers. Use of the interface for PHY timers will
need synchronization to ensure there is no overlap with a Tx timestamp.
The interrupt-based response complicates the locking somewhat. We can't use
a simple spinlock. This would require being acquired in
ice_ptp_req_tx_single_tstamp, and released in
ice_ptp_complete_tx_single_tstamp. The ice_ptp_req_tx_single_tstamp
function is called from the threaded IRQ, and the
ice_ptp_complete_tx_single_stamp is called from the low latency IRQ, so we
would need to acquire the lock with IRQs disabled.
To handle this, we'll use a wait queue along with
wait_event_interruptible_locked_irq in the update flows which don't use the
interrupt.
The interrupt flow will acquire the wait queue lock, set the
ATQBAL_FLAGS_INTR_IN_PROGRESS, and then initiate the firmware low latency
request, and unlock the wait queue lock.
Upon receipt of the low latency interrupt, the lock will be acquired, the
ATQBAL_FLAGS_INTR_IN_PROGRESS bit will be cleared, and the firmware
response will be captured, and wake_up_locked() will be called on the wait
queue.
The other flows will use wait_event_interruptible_locked_irq() to wait
until the ATQBAL_FLAGS_INTR_IN_PROGRESS is clear. This function checks the
condition under lock, but does not hold the lock while waiting. On return,
the lock is held, and a return of zero indicates we hold the lock and the
in-progress flag is not set.
This will ensure that threads which need to use the low latency interface
will sleep until they can acquire the lock without any pending low latency
interrupt flow interfering.

interface. A future firmware extension will add support for performing PHY

macros will be confusing once the interface is used for other purposes.
Rename the macros, using the prefix REG_LL_PROXY_H, to better clarify that
this is for the low latency interface.
Additionally add macros for PF_SB_ATQBAH and PF_SB_ATQBAL registers to
better clarify content of this registers as PF_SB_ATQBAH contain low

The ice_read_phy_tstamp_ll_e810 function repeatedly reads the PF_SB_ATQBAL

candidate for using rd32_poll_timeout. However, the default implementation
uses a sleep-based wait. Use read_poll_timeout_atomic macro which is based

in the ice_read_phy_tstamp_ll_e810 function.

Driver shall expose those under specific health reporter, two new
reporters are introduced:
- FW health reporter shall represent global events (problems with the
image, recovery mode);
- Port health reporter shall represent port-specific events (module
failure).
Firmware only reports problems when those are detected, it does not store
active fault list.
Driver will hold only last global and last port-specific event.
Driver will report all events via devlink health report,
so in case of multiple events of the same source they can be reviewed

The new recipe should be added even if exactly the same recipe already
exists with different priority.
Example use case is when the rule is being added from TC tool context.
It should has the highest priority, but if the recipe already exists
the rule will inherit it priority. It can lead to the situation when
the rule added from TC tool has lower priority than expected.
The solution is to check the recipe priority when trying to find
existing one.
Previous recipe is still useful. Example:
RID 8 -> priority 4
RID 10 -> priority 7
The difference is only in priority rest is let's say eth + mac +
direction.
Adding ARP + MAC_A + RX on RID 8, forward to VF0_VSI
After that IP + MAC_B + RX on RID 10 (from TC tool), forward to PF0
Both will work.
In case of adding ARP + MAC_A + RX on RID 8, forward to VF0_VSI
ARP + MAC_A + RX on RID 10, forward to PF0.
Only second one will match, but this is expected.

Split ice_init_hw() call out from ice_init_dev(). Such move enables
pulling the former to be even earlier on call path, what would enable
moving ice_adapter init to be between the two (in subsequent commit).
Such move enables ice_adapter to know about number of PFs.
Do the same for ice_deinit_hw(), so the init and deinit calls could
be easily mirrored.
Next commit will rename unrelated goto labels to unroll prefix.

- 100G per quad on 2 quads, where lanes used are 0 and 4, but PF IDs are

Use correct PHY lane assignment by getting and parsing port options.
This is read from the NVM by the FW and provided to the driver with

create a kthread worker and affine it using kthread_bind_mask() or
kthread_affine_preferred() before starting it.

ptp4l application reports too high offset when ran on E823 device
with a 100GB/s link. Those values cannot go under 100ns, like in a
working case when using 100 GB/s cable.
This is due to incorrect frequency settings on the PHY clocks for
100 GB/s speed. Changes are introduced to align with the internal
hardware documentation, and correctly initialize frequency in PHY
clocks with the frequency values that are in our HW spec.
To reproduce the issue run ptp4l as a Time Receiver on E823 device,
and observe the offset, which will never approach values seen
in the PTP working case.

The ice_copy_rxq_ctx_to_hw() and ice_write_rxq_ctx() functions perform some
defensive checks which are typically frowned upon by kernel style
guidelines.
In particular, NULL checks on buffers which point to the stack are
discouraged, especially when the functions are static and only called once.
Checks of this sort only serve to hide potential programming error, as we
will not produce the normal crash dump on a NULL access.
In addition, ice_copy_rxq_ctx_to_hw() cannot fail in another way, so could
be made void.
Future support for VF Live Migration will need to introduce an inverse
function for reading Rx queue context from HW registers to unpack it, as
well as functions to pack and unpack Tx queue context from HW.
Rather than copying these style issues into the new functions, lets first
cleanup the existing code.
For the ice_copy_rxq_ctx_to_hw() function:
* Move the Rx queue index check out of this function.
* Convert the function to a void return.
* Use a simple int variable instead of a u8 for the for loop index, and
initialize it inside the for loop.
* Update the function description to better align with kernel doc style.
For the ice_write_rxq_ctx() function:
* Move the Rx queue index check into this function.
* Update the function description with a Returns: to align with kernel doc
style.
These changes align the existing write functions to current kernel
style, and will align with the style of the new functions added when we
implement live migration in a future series.

The ice_write_rxq_ctx() function is responsible for programming the Rx
Queue context into hardware. It receives the configuration in unpacked form
via the ice_rlan_ctx structure.
This function unconditionally modifies the context to set the prefetch
enable bit. This was done by commit c31a5c25bb ("ice: Always set prefena
when configuring an Rx queue"). Setting this bit makes sense, since
prefetching descriptors is almost always the preferred behavior.
However, the ice_write_rxq_ctx() function is not the place that actually
defines the queue context. We initialize the Rx Queue context in
ice_setup_rx_ctx(). It is surprising to have the Rx queue context changed
by a function who's responsibility is to program the given context to
hardware.
Following the principle of least surprise, move the setting of the prefetch
enable bit out of ice_write_rxq_ctx() and into the ice_setup_rx_ctx().

The ice_rlan_ctx and ice_tlan_ctx structures have some fields which are
intentionally sized larger than necessary relative to the packed sizes the
data must fit into. This was done because the original ice_set_ctx()
function and its helpers did not correctly handle packing when the packed
bits straddled a byte. This is no longer the case with the use of the
<linux/packing.h> implementation.
Save some bytes in these structures by sizing the variables to the number
of bytes the actual bitpacked fields fit into.
There are a couple of gaps left in the structure, which is a result of the
fields being in the order they appear in the packed bit layout, but where
alignment forces some extra gaps. We could fix this, saving ~8 bytes from
each structure. However, these structures are not used heavily, and the
resulting savings is minimal:
$ bloat-o-meter ice-before-reorder.ko ice-after-reorder.ko
add/remove: 0/0 grow/shrink: 1/1 up/down: 26/-70 (-44)
Function old new delta
ice_vsi_cfg_txq 1873 1899 +26
ice_setup_rx_ctx.constprop 1529 1459 -70
Total: Before=1459555, After=1459511, chg -0.00%
Thus, the fields are left in the same order as the packed bit layout,
despite the gaps this causes.

The ice driver needs to write the Tx and Rx queue context when programming
Tx and Rx queues. This is currently done using some bespoke custom logic
via the ice_set_ctx() and its helper functions, along with bit position
definitions in the ice_tlan_ctx_info and ice_rlan_ctx_info structures.
This logic does work, but is problematic for several reasons:
1) ice_set_ctx requires a helper function for each byte size being packed,
as it uses a separate function to pack u8, u16, u32, and u64 fields.
This requires 4 functions which contain near-duplicate logic with the
types changed out.
2) The logic in the ice_pack_ctx_word, ice_pack_ctx_dword, and
ice_pack_ctx_qword does not handle values which straddle alignment
boundaries very well. This requires that several fields in the
ice_tlan_ctx_info and ice_rlan_ctx_info be a size larger than their bit
size should require.
3) Future support for live migration will require adding unpacking
functions to take the packed hardware context and unpack it into the
ice_rlan_ctx and ice_tlan_ctx structures. Implementing this would
require implementing ice_get_ctx, and its associated helper functions,
which essentially doubles the amount of code required.
The Linux kernel has had a packing library that can handle this logic since
commit 554aae3500 ("lib: Add support for generic packing operations").
The library was recently extended with support for packing or unpacking an
array of fields, with a similar structure as the ice_ctx_ele structure.
Replace the ice-specific ice_set_ctx() logic with the recently added
pack_fields and packed_field_s infrastructure from <linux/packing.h>
For API simplicity, the Tx and Rx queue context are programmed using
separate ice_pack_txq_ctx() and ice_pack_rxq_ctx(). This avoids needing to
export the packed_field_s arrays. The functions can pointers to the
appropriate ice_txq_ctx_buf_t and ice_rxq_ctx_buf_t types, ensuring that
only buffers of the appropriate size are passed.

The ice Tx and Rx queue context are currently stored as arrays of bytes
with defined size (ICE_RXQ_CTX_SZ and ICE_TXQ_CTX_SZ). The packed queue
context is often passed to other functions as a simple u8 * pointer, which
does not allow tracking the size. This makes the queue context API easy to
misuse, as you can pass an arbitrary u8 array or pointer.
Introduce wrapper typedefs which use a __packed structure that has the
proper fixed size for the Tx and Rx context buffers. This enables the
compiler to track the size of the value and ensures that passing the wrong
buffer size will be detected by the compiler.
The existing APIs do not benefit much from this change, however the
wrapping structures will be used to simplify the arguments of new packing
functions based on the recently introduced pack_fields API.

In switchdev mode the uplink VSI should receive all unmatched packets,
including VLANs. Therefore, VLAN pruning should be disabled if uplink is
in switchdev mode. It is already being done in ice_eswitch_setup_env(),
however the addition of ice_up() in commit 44ba608db5 ("ice: do
switchdev slow-path Rx using PF VSI") caused VLAN pruning to be
re-enabled after disabling it.
Add a check to ice_set_vlan_filtering_features() to ensure VLAN
filtering will not be enabled if uplink is in switchdev mode. Note that
ice_is_eswitch_mode_switchdev() is being used instead of
ice_is_switchdev_running(), as the latter would only return true after
the whole switchdev setup completes.

To check if PHY Clock Recovery mechanic is available for a device, there
is a need to verify if given PHY is available within the netlist, but the
netlist node type used for the search is wrong, also the search context
shall be specified.
Modify the search function to allow specifying the context in the
search.
Use the PHY node type instead of CLOCK CONTROLLER type, also use proper
search context which for PHY search is PORT, as defined in E810
Datasheet [1] ('3.3.8.2.4 Node Part Number and Node Options (0x0003)' and
'Table 3-105. Program Topology Device NVM Admin Command').
