1dba41c9 - net: ipa: add an interconnect dependency

Tue, 01 Mar 2022 11:34:40 +0000

net: ipa: add an interconnect dependencyIn order to function, the IPA driver very clearly requires theinterconnect framework to be enabled in the kernel configuration.State that dependency in the Kconfig file.This became a problem when CONFIG_COMPILE_TEST support was added.Non-Qualcomm platforms won't necessarily enable CONFIG_INTERCONNECT.Reported-by: kernel test robot Fixes: 38a4066f593c5 ("net: ipa: support COMPILE_TEST")Signed-off-by: Alex Elder Link: https://lore.kernel.org/r/20220301113440.257916-1-elder@linaro.orgSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ipa/Kconfig

caef14b7 - net: ipa: fix a build dependency

Fri, 25 Feb 2022 20:15:30 +0000

net: ipa: fix a build dependencyAn IPA build problem arose in the linux-next tree the other day.The problem is that a recent commit adds a new dependency on somecode, and the Kconfig file for IPA doesn't reflect that dependency.As a result, some configurations can fail to build (particularlywhen COMPILE_TEST is enabled).The recent patch adds calls to qmp_get(), qmp_put(), and qmp_send(),and those are built based on the QCOM_AOSS_QMP config option. Ifthat symbol is not defined, stubs are defined, so we just need toensure QCOM_AOSS_QMP is compatible with QCOM_IPA, or it's notdefined.Reported-by: Randy Dunlap Fixes: 34a081761e4e3 ("net: ipa: request IPA register values be retained")Signed-off-by: Alex Elder Tested-by: Randy Dunlap Acked-by: Randy Dunlap Signed-off-by: David S.

424953cf - qcom_scm: hide Kconfig symbol

Tue, 28 Sep 2021 07:50:27 +0000

qcom_scm: hide Kconfig symbolNow that SCM can be a loadable module, we have to add anotherdependency to avoid link failures when ipa or adreno-gpu arebuilt-in:aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe':ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available'ld.lld: error: undefined symbol: qcom_scm_is_available>>> referenced by adreno_gpu.c>>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.aThis can happen when CONFIG_ARCH_QCOM is disabled and we don't selectQCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'duse a similar dependency here to what we have for QCOM_RPROC_COMMON,but that causes dependency loops from other things selecting QCOM_SCM.This appears to be an endless problem, so try something different thistime: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.Acked-by: Kalle Valo Acked-by: Alex Elder Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/net/ipa/Kconfig

fc566dab - net: ipa: switch to version based configuration

Sun, 28 Mar 2021 17:31:08 +0000

net: ipa: switch to version based configurationRename the SDM845 configuration data file so that its name isderived from its IPA version. I am not aware of any special IPAbehavior or handling that would be based on a specific SoC (asopposed to a specific version of the IPA it contains).Update a few other references to the code that talk about the SDM845rather than just IPA v3.5.1.Signed-off-by: Alex Elder Signed-off-by: David S.

99e75a37 - net: ipa: relax 64-bit build requirement

Thu, 18 Mar 2021 18:59:30 +0000

net: ipa: relax 64-bit build requirementWe currently assume the IPA driver is built only for a 64 bit kernel.When this constraint was put in place it eliminated some do_div()calls, replacing them with the "/" and "%" operators. We now onlyuse these operations on u32 and size_t objects. In a 32-bit kernelbuild, size_t will be 32 bits wide, so there remains no reason touse do_div() for divide and modulo.A few recent commits also fix some code that assumes that DMAaddresses are 64 bits wide.With that, we can get rid of the 64-bit build requirement.Signed-off-by: Alex Elder Signed-off-by: David S.

46e05e1d - net: ipa: add config dependency on QCOM_SMEM

Tue, 12 Jan 2021 19:21:34 +0000

net: ipa: add config dependency on QCOM_SMEMThe IPA driver depends on some SMEM functionality (qcom_smem_init(),qcom_smem_alloc(), and qcom_smem_virt_to_phys()), but this is notreflected in the configuration dependencies. Add a dependency onQCOM_SMEM to avoid attempts to build the IPA driver without SMEM.This avoids a link error for certain configurations.Reported-by: Randy Dunlap Fixes: 38a4066f593c5 ("net: ipa: support COMPILE_TEST")Signed-off-by: Alex Elder Acked-by: Randy Dunlap # build-testedReviewed-by: Bjorn Andersson Link: https://lore.kernel.org/r/20210112192134.493-1-elder@linaro.orgSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ipa/Kconfig

5e0ef51b - remoteproc: clean up notification config

Mon, 16 Mar 2020 22:51:21 +0000

remoteproc: clean up notification configRearrange the config files for remoteproc and IPA to fix theirinterdependencies.First, have CONFIG_QCOM_Q6V5_MSS select QCOM_Q6V5_IPA_NOTIFY so thenotification code is built regardless of whether IPA needs it.Next, represent QCOM_IPA as being dependent on QCOM_Q6V5_MSS ratherthan setting its value to match QCOM_Q6V5_COMMON (which is selectedby QCOM_Q6V5_MSS).Drop all dependencies from QCOM_Q6V5_IPA_NOTIFY. The notificationcode will be built whenever QCOM_Q6V5_MSS is set, and it has no otherdependencies.Signed-off-by: Alex Elder Reviewed-by: Bjorn Andersson Signed-off-by: David S.
