Board files enables the mss node
and overloads the compatible depending
on the platform it is expected to
run on. So pretty much the same
node with just changing the compatible
and few additional properties support
both methods. Patch 9 is complete in
itself i.e. it is compliant with
the pas yaml, while patch 10 adds
the bits required to make alternate
method work.

Move rmtfs memory region so that it does not overlap with system
RAM (kernel data) when KAsan is enabled. This puts rmtfs right
after mba_mem which is not supposed to increase beyond 0x94600000

binding check for qcom,pil-info.yaml
didn't complain so I just followed
it. AFAICS, sram isn't mentioned in
generic node names either.

Sure, it makes sense to incorporate
a warn_on and memset the remainder

I split it into two separate
patches just to show that sc7280
supports two ways of bringing
modem out of reset and method
used is determined by the platform.

yeah noticed ^^ but that's the style
we've maintained till now. This
would get cleanup up when I do the
yaml conversion after the series
lands.

sc7180-mpss-pas actually uses only
cx and mss. The mpss-pas compatible
is overridden by the mss-pil compatible
for all the platforms present upstream
for sc7180, that's the reason we probably
haven't run into any binding check failures.
I'll keep the max-items to 2 and fix-up
the sc7180 power-domain requirements
instead.

This looks odd. Why are we letting the device be removed while it is in
use by other drivers? Can't we pin the device with get_device() so it
can't be removed and then prevent the driver from being removed until
all the consumer drivers drop the reference, i.e. suppress sysfs unbind?
Otherwise it looks like a generic problem that all provider devices,
clks, regulators, gpios, etc. have to deal with and thus this
hand-rolled mechanism can't be right.

Can this go above the pinctrl zone in this file? Preferably sorted

The SC7280 SoC supports a 4-Silver/3-Gold/1-Gold+ configuration and hence
the cpu7 node should point to cpufreq domain 2 instead.

Add out of reset sequence support for modem sub-system on SC7280 SoCs.
It requires access to an additional set of qaccept registers, external
power/clk control registers and halt vq6 register to put the modem back
into reset.

The SID configuration requirement for Modem on SC7280 is similar to the
ones found on SC7180/SDM845 SoCs. So, add the SC7280 modem compatible to
the list to defer the programming of the modem SIDs to the kernel.

Strip out the load state power-domain support from the driver since the
low power mode signalling for the co-processors is now accessible through
the direct qmp message send interface.

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence.
These co-processors enter low-power modes independent to that of the
application processor and the load state resources linked to them are
expected to remain unaltered across system suspend/resume cycles. To
achieve this behavior lets stop using the power-domains exposed by the
AOSS QMP node and replace them with generic qmp_send interface instead.

The load state power-domain, used by the co-processors to notify the
Always on Subsystem (AOSS) that a particular co-processor is up/down,
suffers from the side-effect of changing states during suspend/resume.
However the co-processors enter low-power modes independent to that of
the application processor and their states are expected to remain
unaltered across system suspend/resume cycles. To achieve this behavior
let's drop the load state power-domain and replace them with the qmp
property for all SoCs supporting low power mode signalling.

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence. These co-processors enter
low-power modes independent to that of the application processor and
the load state resources linked to them are expected to remain unaltered
across system suspend/resume cycles. To achieve this behavior let's stop
modeling them as power-domains and replace them with generic qmp_send
interface instead.
https://lore.kernel.org/lkml/20200913034603.GV3715@yoga/
Previous discussion on dropping power-domain support from AOSS QMP driver
Depends on:
aoss yaml: https://patchwork.kernel.org/project/linux-arm-msm/cover/20210709174142.1274554-1-bjorn.andersson@linaro.org/
qmp_send: https://patchwork.kernel.org/project/linux-arm-msm/cover/1623237532-20829-1-git-send-email-sibis@codeaurora.org/
V4:
* Rebase patch 1 due to the aoss-qmp yaml conversion (Dropping Rb).
* Commit message change and sc8180x co-processor addition
to patch 2. [Rob/Bjorn]
* Drop unused pdev and kfree the load state string in q6v5_deinit
/probe path for patch 4. [Matthias]
* Replaced "binding" with "property" across the series. [Matthias]
* Commit message change and drop incorrect cleanup on cooling
device probe failures. [Matthias]
V3:
* Misc. documentation fixes [patch 2]:
- Reduce power-domain maxItems due to load_state pd removal
- Combine compatibles where possible with the load_state pd removal
- Fixup the qcom,qmp ref to phandle type
V2:
* load_state is currently broken on mainline so be safely dropped
without side-effects.
* Rebased on top of qmp_send v3 series.
* Dropped R-b from Stephen and Rob on patch 3 due to the yaml
conversion.
* New patch [12] to drop unused aoss-qmp header.
* Commit message update [patch 1] [Rob]
* Reorder the series [Stephen]

Can you pick the reset bindings
and the reset driver changes
through your tree, Bjorn has
picked up the remainder of the
series.

Move rmtfs memory region so that it does not overlap with system
RAM (kernel data) when KAsan is enabled. This puts rmtfs right
after mba_mem which is not supposed to increase beyond 0x94600000

qcom,sc7280-mpss-pas compatible requires
just the xo clock and one reg space whereas
the qcom,sc7280-mss-pil compatible requires
the additional clks and reg spaces. We just
overload properties where re-use is possible
across boards. Hence it would be wrong to
list those clks/reg spaces as requirements
for the pas compatible.

lol, it's the memory map version number
and it's not entirely internal to qc so
we have been mentioning them in commit
messages from older SoCs. I'll just drop
it when I re-spin the series since it
doesn't add much value.

qmp_get is expected to error out with
-ENODEV since we don't mention a qmp
node in dt. When a client needs to use
qmp in the future we would replace NULL
with the proper load_state string value.

nit: the above sounds as if this patch does all of that, when it only
removes power domain support. Instead you could start with saying what
the patch actually does (remove power domain support), followed by why
PD support isn't needed anymore (now done by sending QMP messages directly).

This isn't really related with the PD removal, right? I wonder if it was
intentional to have _probe() succeed even when the cooling device
registration failed, since the cooling devices aren't essential.
If it is still desirable to fail the change should be done in a separate
patch, unless it is actually related with removing PD support.

Doesn't passing a load_state of NULL cause qcom_q6v5_init() to fail with -EINVAL?

Same as for adsp_probe(), doesn't a load_state of NULL cause _init() to fail?

On which tree is this series based? I guess it must be the remoteproc tree
since the conversion of the binding to YAML isn't in Linus' tree yet,
however the patch doesn't apply cleanly against remoteproc/for-next:
patching file Documentation/devicetree/bindings/remoteproc/qcom,adsp.yaml
Hunk #2 succeeded at 144 (offset -4 lines).
Hunk #3 succeeded at 285 (offset -4 lines).
Hunk #4 succeeded at 416 with fuzz 2 (offset 23 lines).
Hunk #5 succeeded at 492 (offset 25 lines).
Hunk #6 FAILED at 485.

The above essentially is a transcript of the code into prose. For a reader
who isn't familiar with the hardware and might not have access to the
corresponding documentation the exact roles of the ACCEPT registers might
not be evident.
I was looking for something slightly higher level, a one liner here and
there might be enough. E.g. something like 'request to disable the channel
denied, re-enable it' in the loop below, if that is semantically correct.
Is there a typical reason why such a request would be denied, maybe because
the channel was busy? Also why is re-enabling actually required if the
request to disable was denied?
> Let me know if you feel any other parts of the patch requires more
comments as well.
For now it's mainly the code involving the ACCEPT registers and
_disable_channel() in particular.

Sure I'll add more comments to this func.
After lowering the request ^^ we wait
for deny to go high or accept to go low.
If it's the former then we do a request
high and repeat the entire process again.
If it's the latter then its considered
that the takedown is success. Let me know
if you feel any other parts of the patch
requires more comments as well.

A bit of commentary in this branch would do no harm. From the code flow
I can guess that disabling the channel failed when QACCEPT_DENY_REG != 0,
and hence the channel is re-enabled (?) for the next try, and apparently
things are fine when QACCEPT_ACCEPT_REG is 0 after disabling the channel.
Would be good to be a bit more explicit about what all that actually
means.

Add out of reset sequence support for modem sub-system on SC7280 SoCs.
It requires access to an additional set of qaccept registers, external
power/clk control registers and halt vq6 register to put the modem back
into reset.

The SID configuration requirement for Modem on SC7280 is similar to the
ones found on SC7180/SDM845 SoCs. So, add the SC7280 modem compatible to
the list to defer the programming of the modem SIDs to the kernel.

The load state resources are expected to follow the life cycle of the
remote processor it tracks. However, modeling load state resources as
power-domains result in them getting turned off during system suspend
and thereby falling out of sync with the remote processors that are still
on. Fix this by replacing load state resource control through the generic
qmp message send interface instead.

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence.
These co-processors enter low-power modes independent to that of the
application processor and the load state resources linked to them are
expected to remain unaltered across system suspend/resume cycles. To
achieve this behavior lets stop using the power-domains exposed by the
AOSS QMP node and replace them with generic qmp_send interface instead.

The power domains exposed by the AOSS QMP driver control the load state
resources linked to modem, adsp, cdsp remoteprocs. These are used to
notify the Always on Subsystem (AOSS) that a particular co-processor is
up/down. AOSS uses this information to wait for the co-processors to
suspend before starting its sleep sequence. These co-processors enter
low-power modes independent to that of the application processor and
the load state resources linked to them are expected to remain unaltered
across system suspend/resume cycles. To achieve this behavior let's stop
modeling them as power-domains and replace them with generic qmp_send
interface instead.

- Reduce power-domain maxItems due to load_state pd removal
- Combine compatibles where possible with the load_state pd removal
- Fixup the qcom,qmp ref to phandle type
V2:
* load_state is currently broken on mainline so be safely dropped
without side-effects.
* Rebased on top of qmp_send v3 series.
* Dropped R-b from Stephen and Rob on patch 3 due to the yaml
conversion.
* New patch [12] to drop unused aoss-qmp header.
* Commit message update [patch 1] [Rob]
* Reorder the series [Stephen]

The power-domains exposed by AOSS QMP node are used to notify the Always
on Subsystem (AOSS) that a particular co-processor is up/down. These
co-processors enter low-power modes independent to that of the application
processor and their states are expected to remain unaltered across system
suspend/resume cycles. To achieve this behavior let's drop the power-domain
bindings and replace them with generic qmp_send interface instead.

The device tree and pas documentation lists mcx as a required pd for cdsp.
Looks like it was missed while adding the proxy pds in the pas driver.
Bjorn/Vinod you'll need to test this patch before picking it up.

Is this really needed for each CPU? Wouldn't it be enough to create
a 'cpu_data' for each 'policy CPU'?
In any case should this be for_each_possible_cpu() as in _unregister_notifier()
to also support CPUs that may be offline when the notifier is registered?

Memory for 'cpu_data' is not freed in this path.

Could memory usage be a concern on systems with a really high number of CPUs
(e.g. 8k for x86 with MAXSMP)? One could argue that such systems likely have
significant amount of RAM too and a chunk of memory in the order of 100k
wouldn't make a big impact. I'm assuming that 'cpu_data' is only needed for
'policy CPUs'.

yeah there is just one qmp node
used by all remote processors and
we just search for the qmp node.

Just a single cell i.e. handle to the
qmp node. I'll fix this in the re-spin.

We might have to rename the cpu_data variable.
For some architectures, cpu_data is defined as macro. This results in
errors such as
include/linux/devfreq.h:331:27: note: in expansion of macro 'cpu_data'
331 | struct devfreq_cpu_data *cpu_data[NR_CPUS];

From: Saravana Kannan <skannan@codeaurora.org>
Many CPU architectures have caches that can scale independent of the
CPUs. Frequency scaling of the caches is necessary to make sure that the
cache is not a performance bottleneck that leads to poor performance and
power. The same idea applies for RAM/DDR.
To achieve this, this patch adds support for cpu based scaling to the
passive governor. This is accomplished by taking the current frequency
of each CPU frequency domain and then adjust the frequency of the cache
(or any devfreq device) based on the frequency of the CPUs. It listens
to CPU frequency transition notifiers to keep itself up to date on the
current CPU frequency.
To decide the frequency of the device, the governor does one of the
following:
* Derives the optimal devfreq device opp from required-opps property of
the parent cpu opp_table.
* Scales the device frequency in proportion to the CPU frequency. So, if
the CPUs are running at their max frequency, the device runs at its
max frequency. If the CPUs are running at their min frequency, the
device runs at its min frequency. It is interpolated for frequencies
in between.

The patch series exposes functions to enable drivers to send their own
messages to AOSS (Always on Subsystem). It also adds a debugfs node for
qmp so messages can be sent to aoss for debugging and testing purposes.
V4:
* Fix compilation error due to missing qmp_put
* Minor typos [s/tarcks/tracks]
V3:
* Remove devm memory allocation
* Use refcount for qmp handle
* Update qmp_get/qmp_put/qmp_remove function with refcount logic

It can be useful to control the different power states of various
parts of hardware for device testing. Add a debugfs node for qmp so
messages can be sent to aoss for debugging and testing purposes.

driver to hook onto. Expose the send api and create a get function to
enable drivers to send their own messages to aoss.

The load state resources are expected to follow the life cycle of the
remote processor it tracks. However, modeling load state resources as
power-domains result in them getting turned off during system suspend
and thereby falling out of sync with the remote processors that are still
on. Fix this by replacing load state resource control through the generic
qmp message send interface instead.

Use the Qualcomm Mailbox Protocol (QMP) binding to control the load
state resources on SC7180 SoCs and drop deprecated power-domains exposed
by AOSS QMP node.

The power-domains exposed by AOSS QMP node are used to notify the Always
on Subsystem (AOSS) that a particular co-processor is up/down. These
co-processors enter low-power modes independent to that of the application
processor and their states are expected to remain unaltered across system
suspend/resume cycles. To achieve this behavior let's drop the power-domain
bindings and replace them with generic qmp_send interface instead.

The load_state implementation is currently
broken i.e. it currently sends that the
remoteproc is down during suspend. AFAIK it
can be safely dropped without side-effects.

It depends on the epss cpufreq and l3 node.
The reg regions used by the cpufreq and
l3 regions currently overlap and that needs
to be sorted out in cpufreq.

@Jassi, I took the liberty of picking this through the qcom tree, as it
only relates to the dts and not the driver. Also sent you a patch to
update MAINTAINERS to ensure that you will receive future patches in

What other dependencies do we have?
I dropped the reg-names from the cpufreq node and merged that change.

Maybe I'm missing something in your argument here, but I see two issues:
* The changes here requires that the new qcom,qmp property is defined,
or the qcom_qmp_get() will be unable to find the qmp instance.
* Between patch 2 and 5 there's no load_state handling.
Perhaps we can carry the power-domain handling as a fallback i
qcom_qmp_get() fails, for a few releases?
Other than the ordering and backwards compatibility issue I think this
looks good. So can you please respin this based on the later revision of
the qmp patch? (And fix Rob's request on the commit message)

[ Upstream commit 0648c55e3a21ccd816e99b6600d6199fbf39d23a ]
Given that no validation of how much data the firmware loader read in
for a given segment truncated segment files would best case result in a
hash verification failure, without any indication of what went wrong.
Improve this by validating that the firmware loader did return the
amount of data requested.

The code validates that segments of p_memsz bytes of a segment will fit
in the provided memory region, but does not validate that p_filesz bytes
will, which means that an incorrectly crafted ELF header might write
beyond the provided memory region.

Given that no validation of how much data the firmware loader read in
for a given segment truncated segment files would best case result in a
hash verification failure, without any indication of what went wrong.
Improve this by validating that the firmware loader did return the
amount of data requested.

Lets skip pulling in 2/2 for now. It depends
on a few other changes to land first and the
cpufreq node for sc7280 needs a re-spin.

nit: one could argue that rounded it's 941 MHz. Same for some other OPPs.
Not super-important though, so:

Given that no validation of how much data the firmware loader read in
for a given segment truncated segment files would best case result in a
hash verification failure, without any indication of what went wrong.
Improve this by validating that the firmware loader did return the

The patch series adds support for DDR/L3 Scaling on SC7280 SoCs.
V3:
* Rename opp table nodes [Matthias]
* Rename opp phandles [Doug]
V2:
* Add a new opp table for cpu 7 to account for the additional frequencies
supported by it.
Depends on the following patch series:
L3 Provider Support: https://lore.kernel.org/lkml/1618556290-28303-1-git-send-email-okukatla@codeaurora.org/
CPUfreq Support: https://lore.kernel.org/lkml/1618020280-5470-2-git-send-email-tdas@codeaurora.org/
RPMH Provider Support: https://lore.kernel.org/lkml/1619517059-12109-1-git-send-email-okukatla@codeaurora.org/
It also depends on L3 and cpufreq dt nodes from the ^^ series to not have
overlapping memory regions.

Add SC7280 to cpufreq-dt-platdev blacklist since the actual scaling is
handled by the 'qcom-cpufreq-hw' driver.

The table provides mapping to bandwidths
which aren't available in the firmware
though. In short we do have to store the
mapping somewhere i.e. a mapping that
lists all possible frequencies to its
bandwidth requirements needs to be present
and using a opp table with the interconnect
bw bindings was the consensus reached.
Given that a duplicate mapping that lists
all possible frequencies to bw is inevitable
and Qualcomm has a way of listing all the
supported frequencies for the SoC, I feel
that dt breakage in the future should be
a non-concern. Not sure why you call it
junk since it solves the perf/power
requirements on SDM845/SC7180 SoCs. When
it becomes obsolete it would mean that
they are better devfreq governors available
upstream and that's a good reason for the
opp tables to go away.

moving the logic to boot loader doesn't
magically fix your concerns though (since
it would also need a superset of available
frequencies). It will suffer from the same
problems with an additional dependency on
firmware propagation in case of breakages
which is something you can avoid for the
simple cpu based scaling solution.

I'll let Viresh take the call since this
solution is already used on older SoCs.

It seems like it might be nicer to give the node labels a less
arbitrary name. How about?
cpu0_opp_300mhz: opp-300000000
That has advantes:
* If, for some reason, you have to mess with some operating point in
another dts it'll be less fragile.
* It'll make diffing easier between SoCs.
* If you end up putting a new operating point in the middle you don't
need to rename everything below.
Other than that, I can't say that I'm a huge expert on the
interconnect stuff and whether those make sense, but I'm still OK

Couldn't omitting the vote result in inconsistent performance at OPPs
w/o DT entry?
Let's assume the Soc has (at least) the following OPPs:
cpu0_opp1: opp-300000000 {
opp-hz = /bits/ 64 <300000000>;
opp-peak-kBps = <800000 9600000>;
};
cpu0_opp3: opp-806400000 {
opp-hz = /bits/ 64 <806400000>;
opp-peak-kBps = <800000 20889600>;
};
/* missing in the device tree */
cpu0_opp4: opp-940800000 {
opp-hz = /bits/ 64 <940800000>;
opp-peak-kBps = <1804000 24576000>;
};
cpu0_opp5: opp-1152000000 {
opp-hz = /bits/ 64 <1152000000>;
opp-peak-kBps = <2188000 27033600>;
};
When the CPU frequency changes from 1.152 GHz to 940.4 MHz the
bandwidth vote is omitted because the new OPP isn't listed in the
DT, the DDR/L3 bandwidth remains at the value for 1.152 GHz, which
is fine in terms of performance, but has a penalty in terms of power.
In case the CPU frequency changes from 806.4 MHz to 940.4 MHz the
bandwidth vote is also omitted, but now the DDR/L3 bandwith stays
at the value for 806.4 MHz, which could have a negative impact on
performance. The impact would be even larger if the switch happened
from a lower OPP, like OPP 1.

Not sure why this warrants a NACK,
as this was consensus for mapping
cpu freq to DDR/L3 bandwidth votes.
(We use the same solution on SDM845
and SC7180). The opp tables are
optional and when specified puts in
votes for DDR/L3. In the future the
table can be safely dropped when more
useful devfreq governors are upstreamed.
cpufreq: qcom: Don't add frequencies without an OPP
I guess your main concern for breakage
is ^^ commit? The original design is
to list a super set of frequencies
supported by all variants of the SoC
along with the required DDR/L3 bandwidth
values. When we run into non-documented
frequency we just wouldn't put in bw
votes for it which should be fine since
the entire opp_table is optional. If
this is the reason for the NACK I can
try get it reverted with Matthias's ack.

NACK, this breaks if there is a mismatch from what is read from the hardware
and what is presented in this table above. Either add it from the some
bootloader or other boot code to this table reading from the hardware/firmware
or find a way to link them without this.
Sorry I had warned long back about this when such links were discussed as
part of interconnect binding.

Had all the dependencies listed in the cover

The patch series adds support for DDR/L3 Scaling on SC7280 SoCs.
V2:
* Add a new opp table for cpu 7 to account for the additional frequencies
supported by it.
Depends on the following patch series:
L3 Provider Support: https://lore.kernel.org/lkml/1618556290-28303-1-git-send-email-okukatla@codeaurora.org/
CPUfreq Support: https://lore.kernel.org/lkml/1618020280-5470-2-git-send-email-tdas@codeaurora.org/
RPMH Provider Support: https://lore.kernel.org/lkml/1619517059-12109-1-git-send-email-okukatla@codeaurora.org/
It also depends on L3 and cpufreq dt nodes from the ^^ series to not have
overlapping memory regions.

This patch seems to depend on the 'Add SC7280 interconnect provider
driver' series (https://patchwork.kernel.org/project/linux-arm-msm/list/?series=473747)
and 'Add L3 provider support for SC7280' (https://patchwork.kernel.org/project/linux-arm-msm/list/?series=468285),
none of them has landed yet. The dependencies should be mentioned in the
commit notes (under '---').

The patch series adds support for DDR/L3 Scaling on SC7280 SoCs.
Depends on the following patch series:
L3 Provider Support: https://lore.kernel.org/lkml/1618556290-28303-1-git-send-email-okukatla@codeaurora.org/
CPUfreq Support: https://lore.kernel.org/lkml/1618020280-5470-2-git-send-email-tdas@codeaurora.org/
RPMH Provider Support: https://lore.kernel.org/lkml/1619517059-12109-1-git-send-email-okukatla@codeaurora.org/
It also depends on L3 and cpufreq dt nodes from the ^^ series to not have
overlapping memory regions.

This series enables miscellaneous hardware blocks to boot Wireless
Processor Subsystem (WPSS) on SC7280 SoC.
V3:
* member placement and style changes [Philipp]
V2:
* place resets and num_resets adjacent to each other [Stephen]
* drop incorrect useage of tcsr_mutex_regs [Bjorn]
* Qualcomm is expected to drop master/slave naming from its mproc nodes
in future SoCs.

Hey Philipp,
Thanks for the review. Will get them
fixed in the next re-spin.
