[ Upstream commit 7fcc17d0cb12938d2b3507973a6f93fc9ed2c7a1 ]
The Energy Model (EM) provides useful information about device power in
each performance state to other subsystems like: Energy Aware Scheduler
(EAS). The energy calculation in EAS does arithmetic operation based on
the EM em_cpu_energy(). Current implementation of that function uses
em_perf_state::cost as a pre-computed cost coefficient equal to:
cost = power * max_frequency / frequency.
The 'power' is expressed in milli-Watts (or in abstract scale).
There are corner cases when the EAS energy calculation for two Performance
Domains (PDs) return the same value. The EAS compares these values to
choose smaller one. It might happen that this values are equal due to
rounding error. In such scenario, we need better resolution, e.g. 1000
times better. To provide this possibility increase the resolution in the
em_perf_state::cost for 64-bit architectures. The cost of increasing
resolution on 32-bit is pretty high (64-bit division) and is not justified
since there are no new 32bit big.LITTLE EAS systems expected which would
benefit from this higher resolution.
This patch allows to avoid the rounding to milli-Watt errors, which might
occur in EAS energy estimation for each PD. The rounding error is common
for small tasks which have small utilization value.
There are two places in the code where it makes a difference:
1. In the find_energy_efficient_cpu() where we are searching for
best_delta. We might suffer there when two PDs return the same result,
like in the example below.
Scenario:
Low utilized system e.g. ~200 sum_util for PD0 and ~220 for PD1. There
are quite a few small tasks ~10-15 util. These tasks would suffer for
the rounding error. These utilization values are typical when running games
on Android. One of our partners has reported 5..10mA less battery drain
when running with increased resolution.
Some details:
We have two PDs: PD0 (big) and PD1 (little)
Let's compare w/o patch set ('old') and w/ patch set ('new')
We are comparing energy w/ task and w/o task placed in the PDs
a) 'old' w/o patch set, PD0

cost = 480
sum_util_w/o_task = 215
sum_util_w_task = 228
scale_cpu = 1024
energy_w/o_task = 480 * 215 / 1024 = 100.78 => 100
energy_w_task = 480 * 228 / 1024 = 106.87 => 106
energy_diff = 106 - 100 = 6
(this is equal to 'old' PD1's energy_diff in 'c)')
b) 'new' w/ patch set, PD0
task_util = 13
cost = 480 * 1000 = 480000
sum_util_w/o_task = 215
sum_util_w_task = 228
energy_w/o_task = 480000 * 215 / 1024 = 100781
energy_w_task = 480000 * 228 / 1024 = 106875
energy_diff = 106875 - 100781 = 6094
(this is not equal to 'new' PD1's energy_diff in 'd)')
c) 'old' w/o patch set, PD1
task_util = 13
cost = 160
sum_util_w/o_task = 283
sum_util_w_task = 293
scale_cpu = 355
energy_w/o_task = 160 * 283 / 355 = 127.55 => 127
energy_w_task = 160 * 296 / 355 = 133.41 => 133
energy_diff = 133 - 127 = 6
(this is equal to 'old' PD0's energy_diff in 'a)')
d) 'new' w/ patch set, PD1
task_util = 13
cost = 160 * 1000 = 160000
sum_util_w/o_task = 283
sum_util_w_task = 293

energy_w_task = 160000 * 296 / 355 = 133408
energy_diff = 133408 - 127549 = 5859
(this is not equal to 'new' PD0's energy_diff in 'b)')
2. Difference in the 6% energy margin filter at the end of
find_energy_efficient_cpu(). With this patch the margin comparison also
has better resolution, so it's possible to have better task placement
thanks to that.

The SMSM driver detects interrupt edges by tracking the last state
it has seen (and has triggered the interrupt handler for). This works
fine, but only if the interrupt does not change state while masked.
For example, if an interrupt is unmasked while the state is HIGH,
the stored last_value for that interrupt might still be LOW. Then,
when the remote processor triggers smsm_intr() we assume that nothing
has changed, even though the state might have changed from HIGH to LOW.
Attempt to fix this by checking the current remote state before
unmasking an IRQ. Use atomic operations to avoid the interrupt handler
from interfering with the unmask function.
This fixes modem crashes in some edge cases with the BAM-DMUX driver.
Specifically, the BAM-DMUX interrupt handler is not called for the
HIGH -> LOW smsm state transition if the BAM-DMUX driver is loaded
(and therefore unmasks the interrupt) after the modem was already started:

the device goes into D3cold, the device itself will end up in D3cold
too, so if it can signal PME from D3cold, it should be enabled to

It is inconsistent to return PCI_D0 from pci_target_state() instead
of the original target state if 'wakeup' is true and the device
cannot signal PME from D0.
This only happens when the device cannot signal PME from the original
target state and any shallower power states (including D0) and that
case is effectively equivalent to the one in which PME singaling is
not supported at all. Since the original target state is returned in
the latter case, make the function do that in the former one too.

[ Upstream commit 64f67b5240db79eceb0bd57dae8e591fd3103ba0 ]
Some 2-in-1s with a detachable (USB) keyboard(dock) have mute-LEDs in
the speaker- and/or mic-mute keys on the keyboard.
Examples of this are the Lenovo Thinkpad10 tablet (with its USB kbd-dock)
and the HP x2 10 series.
The detachable nature of these keyboards means that the keyboard and
thus the mute LEDs may show up after the user (or userspace restoring
old mixer settings) has muted the speaker and/or mic.
Current LED-class devices with a default_trigger of "audio-mute" or
"audio-micmute" initialize the brightness member of led_classdev with
ledtrig_audio_get() before registering the LED.
This makes the software state after attaching the keyboard match the
actual audio mute state, e.g. cat /sys/class/leds/foo/brightness will
show the right value.
But before this commit nothing was actually calling the led_classdev's
brightness_set[_blocking] callback so the value returned by
ledtrig_audio_get() was never actually being sent to the hw, leading
to the mute LEDs staying in their default power-on state, after
attaching the keyboard, even if ledtrig_audio_get() returned a different
state.
This could be fixed by having the individual LED drivers call
brightness_set[_blocking] themselves after registering the LED,
but this really is something which should be done by a led-trigger
activate callback.
Add an activate callback for this, fixing the issue of the
mute LEDs being out of sync after (re)attaching the keyboard.

Some EtherAVB variants support internal clock delay configuration, which
can add larger delays than the delays that are typically supported by
the PHY (using an "rgmii-*id" PHY mode, and/or "[rt]xc-skew-ps"
properties).
Historically, the EtherAVB driver configured these delays based on the
"rgmii-*id" PHY mode. This was wrong, as these are meant solely for the
PHY, not for the MAC. Hence properties were introduced for explicit
configuration of these delays.
Convert the RZ/G2 DTS files from the old to the new scheme:
- Add default "rx-internal-delay-ps" and "tx-internal-delay-ps"
properties to the SoC .dtsi files, to be overridden by board files
where needed,
- Convert board files from "rgmii-*id" PHY modes to "rgmii", adding
the appropriate "rx-internal-delay-ps" and/or "tx-internal-delay-ps"
overrides.
Notes:
- RZ/G2E does not support TX internal delay handling.

[ Upstream commit 0c9856e4edcdcac22d65618e8ceff9eb41447880 ]
There is some sort of corner case behavior of the controller,
which could rarely be triggered at least on i.MX6SX connected
to 800x480 DPI panel and i.MX8MM connected to DPI->DSI->LVDS
bridged 1920x1080 panel (and likely on other setups too), where
the image on the panel shifts to the right and wraps around.
This happens either when the controller is enabled on boot or
even later during run time. The condition does not correct
itself automatically, i.e. the display image remains shifted.
It seems this problem is known and is due to sporadic underflows
of the LCDIF FIFO. While the LCDIF IP does have underflow/overflow
IRQs, neither of the IRQs trigger and neither IRQ status bit is
asserted when this condition occurs.
All known revisions of the LCDIF IP have CTRL1 RECOVER_ON_UNDERFLOW
bit, which is described in the reference manual since i.MX23 as
"
Set this bit to enable the LCDIF block to recover in the next
field/frame if there was an underflow in the current field/frame.
"
Enable this bit to mitigate the sporadic underflows.

In cpuset_hotplug_workfn(), the detection of whether the cpu list
has been changed is done by comparing the effective cpus of the top
cpuset with the cpu_active_mask. However, in the rare case that just
all the CPUs in the subparts_cpus are offlined, the detection fails
and the partition states are not updated correctly. Fix it by forcing
the cpus_updated flag to true in this particular case.

[ Upstream commit 26ab7b384525ccfa678c518577f7f0d841209c8b ]
This commit does a cleanup in LRO configuration.
LRO is a parameter of an RQ, but its state is changed by modifying a TIR
related to the RQ.
The current status: LRO for tunneled packets is not supported in the
driver, inner TIRs may enable LRO on creation, but LRO status of inner
TIRs isn't changed in mlx5e_modify_tirs_lro(). This is inconsistent, but
as long as the firmware doesn't declare support for tunneled LRO, it
works, because the same RQs are shared between the inner and outer TIRs.
This commit does two fixes:
1. If the firmware has the tunneled LRO capability, LRO is blocked
altogether, because it's not possible to block it for inner TIRs only,
when the same RQs are shared between inner and outer TIRs, and the
driver won't be able to handle tunneled LRO traffic.
2. mlx5e_modify_tirs_lro() is patched to modify LRO state for all TIRs,
including inner ones, because all TIRs related to an RQ should agree on
their LRO state.

[ Upstream commit 9c43f3865c2a03be104f1c1d5e9129c2a2bdba88 ]
TIR's rx_hash_field_selector_inner can be enabled only when
tunneled_offload_en = 1. tunneled_offload_en is filled according to the
tunneled_offload_en field in struct mlx5e_params, which is false in the
IPoIB profile. On the other hand, the IPoIB profile passes inner_ttc =
true to mlx5e_create_indirect_tirs, which potentially allows the latter
function to attempt to create inner indirect TIRs without having
tunneled_offload_en set.
This commit prohibits this behavior by passing inner_ttc = false to
mlx5e_create_indirect_tirs. The latter function won't attempt to create
inner indirect TIRs.
As inner indirect TIRs are not created in the IPoIB profile (this commit
blocks it explicitly, and even before they would have failed to be
created), the call to mlx5e_create_inner_ttc_table in
mlx5i_create_flow_steering is a no-op and can be removed.

These are observed while trying to access the GPU's registers when the
MALI clock is running at it's default setting of 24MHz. The 3.10 vendor
kernel uses 318.75MHz as "default" GPU frequency. Using that makes the
"imprecise external aborts" go away.
Add the assigned-clocks and assigned-clock-rates properties to also bump
the MALI clock to 318.75MHz before accessing any of it's registers.

[ Upstream commit 525e2f9fd0229eb10cb460a9e6d978257f24804e ]
st->bucket stores the current bucket number.
st->offset stores the offset within this bucket that is the sk to be
seq_show(). Thus, st->offset only makes sense within the same
st->bucket.
These two variables are an optimization for the common no-lseek case.
When resuming the seq_file iteration (i.e. seq_start()),
tcp_seek_last_pos() tries to continue from the st->offset
at bucket st->bucket.
However, it is possible that the bucket pointed by st->bucket
has changed and st->offset may end up skipping the whole st->bucket
without finding a sk. In this case, tcp_seek_last_pos() currently
continues to satisfy the offset condition in the next (and incorrect)
bucket. Instead, regardless of the offset value, the first sk of the
next bucket should be returned. Thus, "bucket == st->bucket" check is
added to tcp_seek_last_pos().
The chance of hitting this is small and the issue is a decade old,
so targeting for the next tree.
