interconnect: qcom: fix rpmh link failures

2021-01-17T13:17:01+00:00

commit 512d4a26abdbd11c6ffa03032740e5ab3c62c55b upstream.

When CONFIG_COMPILE_TEST is set, it is possible to build some
of the interconnect drivers into the kernel while their dependencies
are loadable modules, which is bad:

arm-linux-gnueabi-ld: drivers/interconnect/qcom/bcm-voter.o: in function `qcom_icc_bcm_voter_commit':
(.text+0x1f8): undefined reference to `rpmh_invalidate'
arm-linux-gnueabi-ld: (.text+0x20c): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: (.text+0x2b0): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: (.text+0x2e8): undefined reference to `rpmh_write_batch'
arm-linux-gnueabi-ld: drivers/interconnect/qcom/icc-rpmh.o: in function `qcom_icc_bcm_init':
(.text+0x2ac): undefined reference to `cmd_db_read_addr'
arm-linux-gnueabi-ld: (.text+0x2c8): undefined reference to `cmd_db_read_aux_data'

The exact dependencies are a bit complicated, so split them out into a
hidden Kconfig symbol that all drivers can in turn depend on to get it
right.

interconnect: qcom: Add SM8250 interconnect provider driver

2020-09-08T13:28:53+00:00

Add driver for the Qualcomm interconnect buses found in SM8250 based
platforms. The topology consists of several NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pairs.

Based on SC7180 driver and generated from downstream dts.

interconnect: qcom: Add OSM L3 interconnect provider support

2020-03-03T17:02:52+00:00

On some Qualcomm SoCs, Operating State Manager (OSM) controls the
resources of scaling L3 caches. Add a driver to handle bandwidth
requests to OSM L3 from CPU on SDM845 SoCs.

interconnect: qcom: Consolidate interconnect RPMh support

2020-02-28T10:11:40+00:00

Add bcm voter driver and add support for RPMh specific interconnect
providers which implements the set and aggregate functionalities that
translates bandwidth requests into RPMh messages. These modules provide
a common set of functionalities for all Qualcomm RPMh based interconnect
providers and should help reduce code duplication when adding new
providers.

interconnect: qcom: remove COMPILE_TEST from CONFIG_INTERCONNECT_QCOM_QCS404

2019-08-15T08:19:12+00:00

There is one compilation error when CONFIG_INTERCONNECT_QCOM_QCS404=y and
CONFIG_INTERCONNECT_QCOM_SMD_RPM=y, as well as CONFIG_COMPILE_TEST=y,
but CONFIG_QCOM_SMD_RPM is not set, logs as below:

drivers/interconnect/qcom/smd-rpm.o: In function `qcom_icc_rpm_smd_send':
smd-rpm.c:(.text+0xe4): undefined reference to `qcom_rpm_smd_write'
Makefile:1071: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

This is because
INTERCONNECT_QCOM_QCS404 depends on QCOM_SMD_RPM || COMPILE_TEST.
Here CONFIG_COMPILE_TEST=y, so CONFIG_INTERCONNECT_QCOM_SMD_RPM
is selected. If CONFIG_QCOM_SMD_RPM is not set, then
qcom_rpm_smd_write() is not defined, and compilation error happen.
Fix this by removing COMPILE_TEST from CONFIG_INTERCONNECT_QCOM_QCS404.
