When the ENA device resets to recover from some error state, all LLQ
configuration values are reset to their defaults, because LLQ is
initialized only once during ena_probe().
Changes in this commit:
1. Move the LLQ configuration process into ena_init_device()
which is called from both ena_probe() and ena_restore_device(). This
way, LLQ setup configurations that are different from the default
values will survive resets.
2. Extract the LLQ bar mapping to ena_map_llq_bar(),
and call once in the lifetime of the driver from ena_probe(),
since there is no need to unmap and map the LLQ bar again every reset.
3. Map the LLQ bar if it exists, regardless if initialization of LLQ
placement policy (ENA_ADMIN_PLACEMENT_POLICY_DEV) succeeded
or not. Initialization might fail the first time, falling back to the
ENA_ADMIN_PLACEMENT_POLICY_HOST placement policy, but later succeed
after device reset, in which case the LLQ bar needs to be mapped
already.

Add the rss_configurable_function_key bit to driver_supported_feature.
This bit tells the device that the driver in question supports the
retrieving and updating of RSS function and hash key, and therefore
the device should allow RSS function and key manipulation.
This commit turns on device support for hash key and RSS function
management. Without this commit this feature is turned off at the
device and appears to the user as unsupported.
This commit concludes the following series of already merged commits:
commit 0af3c4e2ea ("net: ena: changes to RSS hash key allocation")
commit c1bd17e51c ("net: ena: change default RSS hash function to Toeplitz")
commit f66c2ea3b1 ("net: ena: allow setting the hash function without changing the key")
commit e9a1de378d ("net: ena: fix error returning in ena_com_get_hash_function()")
commit 80f8443fcd ("net: ena: avoid unnecessary admin command when RSS function set fails")
commit 6a4f7dc82d ("net: ena: rss: do not allocate key when not supported")
commit 0d1c3de7b8 ("net: ena: fix incorrect default RSS key")
The above commits represent the last part of the implementation of
this feature, and with them merged the feature can be enabled

Add support for traffic mirroring, where the hardware reads the
buffer from the instance memory directly.
Traffic Mirroring needs access to the rx buffers in the instance.
To have this access, this patch:
1. Changes the code to map and unmap the rx buffers bidirectionally.
2. Enables the relevant bit in driver_supported_features to indicate
to the FW that this driver supports traffic mirroring.
Rx completion is not generated until mirroring is done to avoid
the situation where the driver changes the buffer before it is
mirrored.

For an overview of the race created by this patch goto synchronization
label.
In napi busy-poll mode, the kernel invokes the napi handler of the
device repeatedly to poll the NIC's receive queues. This process
repeats until a timeout, specific for each connection, is up.
By polling packets in busy-poll mode the user may gain lower latency
and higher throughput (since the kernel no longer waits for interrupts
to poll the queues) in expense of CPU usage.
Upon completing a napi routine, the driver checks whether
the routine was called by an interrupt handler. If so, the driver
re-enables interrupts for the device. This is needed since an
interrupt routine invocation disables future invocations until
explicitly re-enabled.
The driver avoids re-enabling the interrupts if they were not disabled
in the first place (e.g. if driver in busy mode).
Originally, the driver checked whether interrupt re-enabling is needed
by reading the 'ena_napi->unmask_interrupt' variable. This atomic
variable was set upon interrupt and cleared after re-enabling it.
In the 4.10 Linux version, the 'napi_complete_done' call was changed
so that it returns 'false' when device should not re-enable
interrupts, and 'true' otherwise. The change includes reading the
"NAPIF_STATE_IN_BUSY_POLL" flag to check if the napi call is in
busy-poll mode, and if so, return 'false'.
The driver was changed to re-enable interrupts according to this
routine's return value.
The Linux community rejected the use of the
'ena_napi->unmaunmask_interrupt' variable to determine whether
unmasking is needed, and urged to use napi_napi_complete_done()
return value solely.
See https://lore.kernel.org/patchwork/patch/741149/ for more details
As explained, a busy-poll session exists for a specified timeout
value, after which it exits the busy-poll mode and re-enters it later.
This leads to many invocations of the napi handler where
napi_complete_done() false indicates that interrupts should be
re-enabled.
This creates a bug in which the interrupts are re-enabled
unnecessarily.
To reproduce this bug:
1) echo 50 | sudo tee /proc/sys/net/core/busy_poll
2) echo 50 | sudo tee /proc/sys/net/core/busy_read
3) Add counters that check whether
'ena_unmask_interrupt(tx_ring, rx_ring);'
is called without disabling the interrupts in the first
place (i.e. with calling the interrupt routine
ena_intr_msix_io())
Steps 1+2 enable busy-poll as the default mode for new connections.
The busy poll routine rearms the interrupts after every session by
design, and so we need to add an extra check that the interrupts were
masked in the first place.
synchronization:
This patch introduces a race between the interrupt handler
ena_intr_msix_io() and the napi routine ena_io_poll().
Some macros and instruction were added to prevent this race from leaving
the interrupts masked. The following specifies the different race
scenarios in this patch:
1) interrupt handler and napi routine run sequentially
i) interrupt handler is called, sets 'interrupts_masked' flag and
successfully schedules the napi handler via softirq.
In this scenario the napi routine might not see the flag change
for several reasons:
a) The flag is stored in a register by the compiler. For this
case the WRITE_ONCE macro which prevents this.
b) The compiler might reorder the instruction. For this the
smp_wmb() instruction was used which implies a compiler memory
barrier.
c) On archs with weak consistency model (like ARM64) the napi
routine might be scheduled and start running before the flag
STORE instruction is committed to cache/memory. To ensure this
doesn't happen, the smp_wmb() instruction was added. It ensures
that the flag set instruction is committed before scheduling
napi.
ii) compiler reorders the flag's value check in the 'if' with
the flag set in the napi routine.
This scenario is prevented by smp_rmb() call after the flag check.
2) interrupt handler and napi routine run in parallel (can happen when
busy poll routine invokes the napi handler)
i) interrupt handler sets the flag in one core, while the napi
routine reads it in another core.
This scenario also is divided into two cases:
a) napi_complete_done() doesn't finish running, in which case
napi_sched() would just set NAPIF_STATE_MISSED and the napi
routine would reschedule itself without changing the flag's value.
b) napi_complete_done() finishes running. In this case the
napi routine might override the flag's value.
This doesn't present any rise since it later unmasks the
interrupt vector.

With PCS support, how we implement interface reconfiguration (or other
major reconfiguration) is not up to the job; we end up reconfiguring
the PCS for an interface change while the link could potentially be up.
In order to solve this, add two additional MAC methods for major
configuration, one to prepare for the change, and one to finish the
change.
This allows mvneta and mvpp2 to shutdown what they require prior to the
MAC and PCS configuration calls, and then restart as appropriate.
This impacts ksettings_set(), which now needs to identify whether the
change is a minor tweak to the advertisement masks or whether the
interface mode has changed, and call the appropriate function for that

- The link partner advertisement is set to the link speed with non-

The phylink ethtool output also disagrees with the software emulated

Use the generic dynamic interrupt moderation (dim)
framework to implement adaptive interrupt coalescing
on Rx. With the per-packet interrupt scheme, a high
interrupt rate has been noted for moderate traffic flows
leading to high CPU utilization. The 'dim' scheme
implemented by the current patch addresses this issue
improving CPU utilization while using minimal coalescing
time thresholds in order to preserve a good latency.
On the Tx side use an optimal time threshold value by
default. This value has been optimized for Tx TCP
streams at a rate of around 85kpps on a 1G link,
at which rate half of the Tx ring size (128) gets filled
in 1500 usecs. Scaling this down to 2.5G links yields
the current value of 600 usecs, which is conservative
and gives good enough results for 1G links too (see
next).
Below are some measurement results for before and after
this patch (and related dependencies) basically, for a
2 ARM Cortex-A72 @1.3Ghz CPUs system (32 KB L1 data cache),
using 60secs log netperf TCP stream tests @ 1Gbit link
(maximum throughput):
1) 1 Rx TCP flow, both Rx and Tx processed by the same NAPI
thread on the same CPU:
CPU utilization int rate (ints/sec)
Before: 50%-60% (over 50%) 92k
After: 13%-22% 3.5k-12k
Comment: Major CPU utilization improvement for a single flow
Rx TCP flow (i.e. netperf -t TCP_MAERTS) on a single
CPU. Usually settles under 16% for longer tests.
2) 4 Rx TCP flows + 4 Tx TCP flows (+ pings to check the latency):
Total CPU utilization Total int rate (ints/sec)
Before: ~80% (spikes to 90%) ~100k
After: 60% (more steady) ~4k
Comment: Important improvement for this load test, while the
ping test outcome does not show any notable
difference compared to before.

run-time configurable, also anticipating the dynamic interrupt
moderation (DIM) algorithm which uses fixed packet thresholds

from default per-packet interrupts to coalesced interrupts),
the traffic needs to be paused in the process.

A reliable traffic pause (and reconfiguration) procedure
is needed to be able to safely make h/w configuration
changes during run-time, like changing the mode in which the
interrupts are operating (i.e. with or without coalescing),
as opposed to making on-the-fly register updates that
may be subject to h/w or s/w concurrency issues.
To this end, the code responsible of the run-time device
configurations that basically starts resp. stops the traffic
flow through the device has been extracted from the
the enetc_open/_close procedures, to the separate standalone
enetc_start/_stop procedures. Traffic stop should be as
graceful as possible, it lets the executing napi threads to
to finish while the interrupts stay disabled. But since
the napi thread will try to re-enable interrupts by clearing
the device's unmask register, the enable_irq/ disable_irq
API has been used to avoid this potential concurrency issue
and make the traffic pause procedure more reliable.

It's time to differentiate between Rx and Tx ring sizes.
Not only Tx rings are processed differently than Rx rings,
but their default number also differs - i.e. up to 8 Tx rings
per device (8 traffic classes) vs. 2 Rx rings (one per CPU).
So let's set Tx rings sizes to half the size of the Rx rings
for now, to be conservative.
The default ring sizes were decreased as well (to the next
lower power of 2), to reduce the memory footprint, buffering
etc., since the measurements I've made so far show that the
rings are very unlikely to get full.
This change also anticipates the introduction of the
dynamic interrupt moderation (dim) algorithm which operates
on maximum packet thresholds of 256 packets for Rx and 128
packets for Tx.
