Since MSM8916 is an ARM v8 64-bit SoC the CPU cores are normally booted
using "psci" or "spin-table". Unfortunately, some devices come with signed
32-bit-only firmware without ARM64 and PSCI support. This setup is easy to
support since it's very similar to older 32-bit only Qualcomm SoCs
(e.g. MSM8226) and only requires adding a few new definitions to already
existing drivers.

Document the qcom,msm8916-smp enable-method. It is actually just an alias
of qcom,msm8226-smp since it should be implemented identically.
The enable-method is only valid on ARM32 and must not be used on ARM64.

soc: qcom: rpmhpd: Make power_on actually enable the domain

The general expectation is that powering on a power-domain should make
the power domain deliver some power, and if a specific performance state
is needed further requests has to be made.

But in contrast with other power-domain implementations (e.g. rpmpd) the
RPMh does not have an interface to enable the power, so the driver has
to vote for a particular corner (performance level) in rpmh_power_on().

But the corner is never initialized, so a typical request to simply
enable the power domain would not actually turn on the hardware. Further
more, when no more clients vote for a performance state (i.e. the
aggregated vote is 0) the power domain would be turned off.

Fix both of these issues by always voting for a corner with non-zero
value, when the power domain is enabled.

The tracking of the lowest non-zero corner is performed to handle the
corner case if there's ever a domain with a non-zero lowest corner, in
which case both rpmh_power_on() and rpmh_rpmhpd_set_performance_state()
would be allowed to use this lowest corner.

AngeloGioacchino Del Regno [Thu, 29 Jul 2021 15:56:05 +0000 (17:56 +0200)]
cpuidle: qcom_spm: Detach state machine from main SPM handling

In commit a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a generic
CPUidle driver") the SPM driver has been converted to a
generic CPUidle driver: that was mainly made to simplify the
driver and that was a great accomplishment;
Though, at that time, this driver was only applicable to ARM 32-bit SoCs,
lacking logic about the handling of newer generation SAW.

In preparation for the enablement of SPM features on AArch64/ARM64,
split the cpuidle-qcom-spm driver in two: the CPUIdle related
state machine (currently used only on ARM SoCs) stays there, while
the SPM communication handling lands back in soc/qcom/spm.c and
also making sure to not discard the simplifications that were
introduced in the aforementioned commit.

Since now the "two drivers" are split, the SCM dependency in the
main SPM handling is gone and for this reason it was also possible
to move the SPM initialization early: this will also make sure that
whenever the SAW CPUIdle driver is getting initialized, the SPM
driver will be ready to do the job.

Please note that the anticipation of the SPM initialization was
also done to optimize the boot times on platforms that have their
CPU/L2 idle states managed by other means (such as PSCI), while
needing SAW initialization for other purposes, like AVS control.

2 years agoperf tools: Allow build-id with trailing zeros
Namhyung Kim [Fri, 10 Sep 2021 22:46:30 +0000 (15:46 -0700)]
perf tools: Allow build-id with trailing zeros

Currently perf saves a build-id with size but old versions assumes the
size of 20.  In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.

I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data.  The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.

  symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.

The build-id event in the data has 20 byte build-ids, but it saw a
different size (16) when it reads the build-id of the elf file in the
build-id cache.

  $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf

      Build ID: 53e4c2f42a4c61a2d632d92a72afa08f

Let's fix this by allowing trailing zeros if the size is different.
