From d21d1f33b190f7c18e83899dfbc5a48ab173ef15 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Sun, 28 Mar 2021 12:31:07 -0500 Subject: [PATCH] net: ipa: don't define endpoints unnecessarily We don't typically need much information about modem endpoints. Normally we need to specify information about modem endpoints in configuration data in only two cases: - When a modem TX endpoint supports filtering - When another endpoint's configuration refers to it For the first case, the AP initializes the filter table, and must know how many endpoints (AP and modem) support filtering. An example of the second case is the AP->modem TX endpoint, which defines the modem<-AP RX endpoint as its status endpoint. There is one exception to this, and it's due to a hardware quirk. For IPA v4.2 (only) there is a problem related to allocating GSI channels. And to work around this, the AP allocates *all* GSI channels at startup time--including those used by the modem. Get rid of the configuration information for two endpoints not required for the SDM845. SC7180 runs IPA v4.2, so we can't eliminate any modem endpoint definitions there. Two more minor changes: - Reorder the members defined for the ipa_endpoint_name enumerated type to match the order used in configuration data files when defining endpoints. - Add a new name, IPA_ENDPOINT_MODEM_DL_NLO_TX, which can be used for IPA v4.5+.
