This series gathers a set of IPA driver cleanups, mostly involving code that ensures certain things are known to be correct *early* (either at build or initializatin time), so they can be assumed good during normal operation. The first removes three constant symbols, by making a (reasonable) assumption that a routing table consists of entries for the modem followed by entries for the AP, with no unused entries between them. The second removes two checks that are redundant (they verify the sizes of two memory regions are in range, which will have been done earlier for all regions). The third adds some new checks to routing and filter tables that can be done at "init time" (without requiring any access to IPA hardware). The fourth moves a check that routing and filter table addresses can be encoded within certain IPA immediate commands, so it's performed earlier; the checks can be done without touching IPA hardware. The fifth moves some other command-related checks earlier, for the same reason. The sixth removes the definition ipa_table_valid(), because what it does has become redundant. Finally, the last patch moves two more validation calls so they're done very early in the probe process. This will be required by some upcoming patches, which will record the size of the routing and filter tables at this time so they're available for subsequent initialization. -Alex Alex Elder (7): net: ipa: kill two constant symbols net: ipa: remove two memory region checks net: ipa: validate IPA table memory earlier net: ipa: verify table sizes fit in commands early net: ipa: introduce ipa_cmd_init() net: ipa: kill ipa_table_valid() net: ipa: check table memory regions earlier drivers/net/ipa/ipa_cmd.c | 53 ++++-------- drivers/net/ipa/ipa_cmd.h | 16 +++- drivers/net/ipa/ipa_mem.c | 14 ++-- drivers/net/ipa/ipa_table.c | 162 +++++++++++++++++++++--------------- drivers/net/ipa/ipa_table.h | 15 ++-- 5 files changed, 138 insertions(+), 122 deletions(-) -- 2.34.1
