In order to support installing an XDP program on DQ, RX buffers need to
be reposted using 4K buffers, which is larger than the default packet
buffer size of 2K. This is needed to accommodate the extra head and tail
that accompanies the data portion of an XDP buffer. Continuing to use 2K
buffers would mean that the packet buffer size for the NIC would have to
be restricted to 2048 - 320 - 256 = 1472B. However, this is problematic
for two reasons: first, 1472 is not a packet buffer size accepted by
GVE; second, at least 1474B of buffer space is needed to accommodate an
MTU of 1460, which is the default on GCP. As such, we allocate 4K
buffers, and post a 2K section of those 4K buffers (offset relative to
the XDP headroom) to the NIC for DMA to avoid a potential extra copy.
Because the GQ-QPL datapath requires copies regardless, this change was
not needed to support XDP in that case.
To capture this subtlety, a new field, packet_buffer_truesize, has been
added to the rx ring struct to represent size of the allocated buffer,
while packet_buffer_size has been left to represent the portion of the
buffer posted to the NIC.

The data_buffer_size_dqo field in gve_priv and the packet_buffer_size
field in gve_rx_ring theoretically have the same meaning, but they are
defined in two different places and used in two separate contexts. There
is no good reason for this, so this change merges those fields into the
packet_buffer_size field in the RX ring.
This change also introduces a packet_buffer_size field to struct
gve_rx_queue_config to account for cases where queues are not allocated,
such as when the interface is down.

Commit ebdfae0d37 ("gve: adopt page pool for DQ RDA mode") introduced
a buf_size field to the gve_rx_slot_page_info struct, which can be used
in the datapath to take the place of the packet_buffer_size field, as it
will already be hot in the cache due to its extensive use. Using the
buf_size field in the datapath frees up the packet_buffer_size field in
the GQ-specific RX cacheline to be generalized for GQ and DQ (in the
next patch), as there is currently no common packet buffer size field
between the two queue formats.

An earlier patch series[1] introduced RX/TX ring allocation configuration
structs which contained metadata used to allocate and configure new RX
and TX rings. This led to a much cleaner and safer allocation pattern
wherein queue resources were not deallocated until new queue resources
were successfully allocated.
Migrate the XDP allocation path to use the same pattern to allow for the
existence of a single allocation path instead of relying on XDP-specific
allocation methods. These extra allocation methods result in the
duplication of many existing behaviors while being prone to error when
configuration changes unrelated to XDP occur.

On ILK-IVB only PCH outputs use shared dplls. Move the relevant
intel_disable_shared_dpll() into ilk_pch_post_disable() to make
that clear (and if we extend the dpll mgr to cover all plls we need
different enable/disable points anyway for the PCH vs. CPU eDP cases).
The intel_enable_shared_dpll() counterpart was already in
ilk_pch_enable() anyway, so this is the more symmetric place for the

Currently we loop over all joined pipes and enable/disable the
shared dplls for each. We don't really have to do that since
all joined pipes will be using the same dpll. So let's just do
the enable/disable once for the whole set of joined pipes.
We can still keep tracking the dpll active set as pipes as long
as we remember to flip the bits for all the joined pipes on one go.

Only sensors that are valid need to have their interrupts enable status
updated based on their thresholds. Use the lvts_for_each_valid_sensor()
helper in lvts_update_irq_mask() to ignore invalid sensors.
Currently, since the invalid sensors will always contain zeroed out
thresholds (from kzalloc), they will always get their interrupts
disabled on this loop. So this commit doesn't change the resulting
interrupts configuration, but it slightly optimizes the loop by skipping
the invalid sensors, avoids potential future surprises if at some point
memory is no longer allocated for invalid sensors, as well as makes the
code more obvious.

In order to get working interrupts, a low offset value needs to be
configured. The minimum value for it is 20 Celsius, which is what is
configured when there's no lower thermal trip (ie the thermal core
passes -INT_MAX as low trip temperature). However, when the temperature
gets that low and fluctuates around that value it causes an interrupt
storm.
Prevent that interrupt storm by not enabling the low offset interrupt if
the low threshold is the minimum one.

The Stage 3 thermal threshold is currently configured during
the controller initialization to 105 Celsius. From the kernel
perspective, this configuration is harmful because:
* The stage 3 interrupt that gets triggered when the threshold is
crossed is not handled in any way by the IRQ handler, it just gets
cleared. Besides, the temperature used for stage 3 comes from the
sensors, and the critical thermal trip points described in the
Devicetree will already cause a shutdown when crossed (at a lower
temperature, of 100 Celsius, for all SoCs currently using this
driver).
* The only effect of crossing the stage 3 threshold that has been
observed is that it causes the machine to no longer be able to enter
suspend. Even if that was a result of a momentary glitch in the
temperature reading of a sensor (as has been observed on the
MT8192-based Chromebooks).
For those reasons, disable the Stage 3 thermal threshold configuration.

When configured in filtered mode, the LVTS thermal controller will
monitor the temperature from the sensors and trigger an interrupt once a
thermal threshold is crossed.
Currently this is true even during suspend and resume. The problem with
that is that when enabling the internal clock of the LVTS controller in
lvts_ctrl_set_enable() during resume, the temperature reading can glitch
and appear much higher than the real one, resulting in a spurious
interrupt getting generated.
Disable the temperature monitoring and give some time for the signals to
stabilize during suspend in order to prevent such spurious interrupts.

the equation for the output when tsadc_q_sel equals 1 is (4096 -
tsadc_q), while part 1 of the RK3328 TRM v1.2 says that the output
equation is (1024 - tsadc_q) in that case.
The downstream kernel code, however, treats the RK3308 and RK3328
tables and their values as being the same. It even mentions 1024 as
the "offset" value in a comment block for the rk_tsadcv3_control()
function, just like the upstream code does, which is obviously wrong
"offset" value when correlated with the table on page 544 of part 1
of the RK3308 TRM v1.1.
With all this in mind, it's obvious that more work is needed to make
it clear where's the actual mistake (it could be that the TRM is
wrong), which I'll volunteer for as part of the SoC binning project.
In the meantime, this patch looks fine as-is to me, by offering
what's a clear improvement to the current state of the upstream
code"

SoCs without RPM need to enable sensors and calibrate them from the kernel.
The IPQ5332 and IPQ5424 use the tsens v2.3.3 IP and do not have RPM.
Therefore, add a new calibration function for V2, as the tsens.c calib
function only supports V1. Also add new feature_config, ops and data for
IPQ5332, IPQ5424.
Although the TSENS IP supports 16 sensors, not all are used. The hw_id
is used to enable the relevant sensors.

The UAPI change seems safe as there are currently no drivers that
declare support for devmem TCP RX via PP_FLAG_ALLOW_UNREADABLE_NETMEM.
Hence, fixing this UAPI should be safe.

Some controllers seems to generate HCI_EV_LE_DIRECT_ADV_REPORT even when

auto-connect logic:

- Consolidate the VDSO storage
The VDSO data storage and data layout has been largely architecture
specific for historical reasons. That increases the maintenance effort
and causes inconsistencies over and over.
There is no real technical reason for architecture specific layouts and
implementations. The architecture specific details can easily be
integrated into a generic layout, which also reduces the amount of
duplicated code for managing the mappings.
Convert all architectures over to a unified layout and common mapping
infrastructure. This splits the VDSO data layout into subsystem
specific blocks, timekeeping, random and architecture parts, which
provides a better structure and allows to improve and update the
functionalities without conflict and interaction.
- Rework the timekeeping data storage
The current implementation is designed for exposing system timekeeping
accessors, which was good enough at the time when it was designed.
PTP and Time Sensitive Networking (TSN) change that as there are
requirements to expose independent PTP clocks, which are not related to
system timekeeping.
Replace the monolithic data storage by a structured layout, which
allows to add support for independent PTP clocks on top while reusing
both the data structures and the time accessor implementations.

Remove KSZ88x3-specific priority and apptrust configuration logic that was
based on incorrect register access assumptions. Also fix the register
offset for KSZ8_REG_PORT_1_CTRL_0 to align with get_port_addr() logic.
The KSZ88x3 switch family uses a different register layout compared to
KSZ9477-compatible variants. Specifically, port control registers need
offset adjustment through get_port_addr(), and do not match the datasheet
values directly.
Commit a1ea57710c ("net: dsa: microchip: dcb: add special handling for
KSZ88X3 family") introduced quirks based on datasheet offsets, which do
not work with the driver's internal addressing model. As a result, these
quirks addressed the wrong ports and caused unstable behavior.
This patch removes all KSZ88x3-specific DCB quirks and corrects the port
control register offset, effectively restoring working and predictable
apptrust configuration.
