soc: qcom: Select REMAP_MMIO for ICC_BWMON driver

2023-01-07T10:11:36Z

commit a84160fbf4f2c8c5ffa588e19ea8f92eabd7ad17 upstream. ICC_BWMON driver uses REGMAP_MMIO for accessing the hardware registers. So select the dependency in Kconfig. Without this, there will be errors while building the driver with COMPILE_TEST only: ERROR: modpost: "__devm_regmap_init_mmio_clk" [drivers/soc/qcom/icc-bwmon.ko] undefined! make[1]: *** [scripts/Makefile.modpost:126: Module.symvers] Error 1 make: *** [Makefile:1944: modpost] Error 2 Cc: # 6.0 Cc: Krzysztof Kozlowski Fixes: b9c2ae6cac40 ("soc: qcom: icc-bwmon: Add bandwidth monitoring driver") Signed-off-by: Manivannan Sadhasivam Reviewed-by: Krzysztof Kozlowski Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20221129072022.41962-1-manivannan.sadhasivam@linaro.org Signed-off-by: Greg Kroah-Hartman

QCOM_RPMPD requires PM_GENERIC_DOMAINS/_OF, which in turns requires CONFIG_PM. I forgot about the latter in my earlier patch (it's still in -next as of the time of committing, hence no Fixes: tag).

soc: qcom: icc-bwmon: Add bandwidth monitoring driver

2022-07-06T20:57:51Z

Bandwidth monitoring (BWMON) sits between various subsytems like CPU, GPU, Last Level caches and memory subsystem. The BWMON can be configured to monitor the data throuhput between memory and other subsytems. The throughput is measured within specified sampling window and is used to vote for corresponding interconnect bandwidth. Current implementation brings support for BWMON v4, used for example on SDM845 to measure bandwidth between CPU (gladiator_noc) and Last Level Cache (memnoc). Usage of this BWMON allows to remove fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high memory throughput even with lower CPU frequencies. The driver was tested on SDM845.

soc/qcom: Make QCOM_RPMPD select PM_GENERIC_DOMAINS/_OF

2022-07-05T16:16:46Z

The driver uses generic genpd OF APIs and with a very minimal config where nothing else selects them, this driver will not probe, as of_genpd_add_provider_onecell will return -EOPNOTSUPP. Make sure to select these in Kconfig to prevent that. Signed-off-by: Konrad Dybcio Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20220701073700.17124-1-konrad.dybcio@somainline.org

soc: qcom: apr: Add GPR support

2021-09-28T03:10:07Z

Qualcomm Generic Packet router aka GPR is the IPC mechanism found in AudioReach next generation signal processing framework to perform command and response messages between various processors. GPR has concepts of static and dynamic port, all static services like APM (Audio Processing Manager), PRM (Proxy resource manager) have fixed port numbers where as dynamic services like graphs have dynamic port numbers which are allocated at runtime. All GPR packet messages will have source and destination domain and port along with opcode and payload.
