[PATCH 0/9] interconnect: qcom: let MSM8974 interconnect work again

[PATCH 0/9] interconnect: qcom: let MSM8974 interconnect work again

[Dmitry Baryshkov]

Commit d6edc31f3a68 ("clk: qcom: smd-rpm: Separate out interconnect bus
clocks") moved control over several RPM resources from the clk-smd-rpm
driver to the icc-rpm.c interconnect helpers. Most of the platforms were
fixed before that commit or shortly after. However the MSM8974 was left
as a foster child in broken state. Fix the loose ends and reenable
interconnects on that platform.

[PATCH 1/9] dt-bindings: interconnect: qcom,msm8974: drop bus clocks

[Dmitry Baryshkov]

Remove the wrong internal RPM bus clock representation that we've been
carrying for years. They are an internal part of the interconnect
fabric. They are not exported by any device and are not supposed to be
used.

[Dmitry Baryshkov]

Use qcom,rpm-common schema to declare interconnects property instead
describing it again. In future this will allow the platform to switch to
the two-cell interconnects, adding the tag to the specification.

Hm, looks like the clock vote is kept all the way from .probe()
to .remove(). I wonder if that's really what should happen..

That's what drivers/interconnect/qcom/holi.c does on msm-5.10

Maybe "iface clocks" are only needed to execute a ->set() on a node?

Well, it's probably up to you to decide. I've a bit lost my way in the
vendor's adhoc / bus / etc. code.

Hmm, I don't know. AXI clocks seems to describe the clocking between the
NoC and a particular device. So maybe it's required for as long as there
is something using the NoC.

[PATCH 4/9] interconnect: qcom: icc-rpm: allow overwriting get_bw callback

[Dmitry Baryshkov]

MSM8974 requires a separate get_bw callback, since on that platform
increasing the clock rate for some of the NoCs during boot may lead to
hangs. For the details see commit 9caf2d956cfa ("interconnect: qcom:
msm8974: Don't boost the NoC rate during boot").

Is there a single specific bus where this causes an issue, or is
setting *any* resource to INT_MAX problematic?

I'd refer this to Luca. I didn't experiment that much (and also note,
this behaviour might be firmware-specific).

My goal for this patchset was to port as close as possible. We can drop
the get_bw later, after enabling more interconnects, writing the QoS,
etc.

Yes. And if you check, these nodes have QoS settings in the DT. Later
kernels have added a guard check (.qos.ap_owned) and dropped mas/slv IDs
for similar nodes.

[PATCH 6/9] interconnect: qcom: let platforms declare their bugginess

[Dmitry Baryshkov]

On MSM8974 programming some of the RPM resources results in the
"resource does not exist" messages from the firmware. This occurs even
with the downstream bus driver, which happily ignores the errors. My
assumption is that these resources existed in the earlier firmware
revisions but were later switched to be programmed differently (for the
later platforms corresponding nodes use qos.ap_owned, which prevents
those resources from being programmed.

In preparation for conversion of the MSM8974 driver (which doesn't have
QoS code yet) to the main icc-rpm set of helpers, let the driver declare
that those -ENXIO errors must be ignored (for now). Later, when the QoS
programming is sorted out (and more interconnects are added to the DT),
this quirk might be removed.

Not super happy about this, but since it's transitional:

When I wrote the msm8974 icc driver, I spent a fair bit of time trying
to make it so that we didn't have to ignore those errors. As you
mentioned, the downstream msm bus code gives the same errors. That
downstream code was the only reference material that I had access to
when I wrote this driver.

[PATCH 7/9] interconnect: qcom: msm8974: switch to the main icc-rpm driver

[Dmitry Baryshkov]

In preparation to restoring the ability of MSM8974 driver to work with
the modern kernels, switch the driver to the main icc-rpm set of helper
code.

As platform-specific workarounds, set the get_bw callback (returning 0)
to prevent initial setup from programming INT_MAX into the RPM (which
otherwise might hang the platform) and tell RPM programming code to
ignore -ENXIO errors from the firmware (until the QoS programming is
sorted out).

[PATCH 8/9] interconnect: qcom: msm8974: expand DEFINE_QNODE macros

[Dmitry Baryshkov]

The rest of Qualcomm Interconnect drivers have stopped using
DEFINE_QNODE long ago for the sake of readability. Stop using it inside
the msm8974 interconnect driver too.

[PATCH 9/9] ARM: dts: qcom: msm8974: Drop RPM bus clocks

[Dmitry Baryshkov]

Some nodes are abusingly referencing some of the internal bus clocks,
that were recently removed in Linux (because the original implementation
did not make much sense), managing them as if they were the only devices
on an NoC bus.

These clocks are now handled from within the icc framework and are
no longer registered from within the CCF. Remove them.

Do we still enforce C-style comments?

Also "unused" is not really right.. After the 'revolution', SMD_RPM_CC
no longer ""provides"" that clock in reality, since it was never a "clock"
but rather an interconnect resource
