2021-03-28net: ipa: switch to version based configurationAlex Elder1-2/+1
Rename the SDM845 configuration data file so that its name is derived from its IPA version. I am not aware of any special IPA behavior or handling that would be based on a specific SoC (as opposed to a specific version of the IPA it contains). Update a few other references to the code that talk about the SDM845 rather than just IPA v3.5.1. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-03-18net: ipa: relax 64-bit build requirementAlex Elder1-1/+1
We 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 only use these operations on u32 and size_t objects. In a 32-bit kernel build, size_t will be 32 bits wide, so there remains no reason to use do_div() for divide and modulo. A few recent commits also fix some code that assumes that DMA addresses are 64 bits wide. With that, we can get rid of the 64-bit build requirement.

2021-01-12net: ipa: add config dependency on QCOM_SMEMAlex Elder1-1/+1
The IPA driver depends on some SMEM functionality (qcom_smem_init(), qcom_smem_alloc(), and qcom_smem_virt_to_phys()), but this is not reflected in the configuration dependencies. Add a dependency on QCOM_SMEM to avoid attempts to build the IPA driver without SMEM. This avoids a link error for certain configurations.

2021-01-09net: ipa: support COMPILE_TESTAlex Elder1-4/+6
Arrange for the IPA driver to be built when COMPILE_TEST is enabled. Update the help text to reflect that we support two Qualcomm SoCs.

2020-03-16remoteproc: clean up notification configAlex Elder1-1/+1
Rearrange the config files for remoteproc and IPA to fix their interdependencies. First, have CONFIG_QCOM_Q6V5_MSS select QCOM_Q6V5_IPA_NOTIFY so the notification code is built regardless of whether IPA needs it. Next, represent QCOM_IPA as being dependent on QCOM_Q6V5_MSS rather than setting its value to match QCOM_Q6V5_COMMON (which is selected by QCOM_Q6V5_MSS). Drop all dependencies from QCOM_Q6V5_IPA_NOTIFY. The notification code will be built whenever QCOM_Q6V5_MSS is set, and it has no other dependencies.
