On a modular chassis, add a GLOBAL_STATE_DB where all state information from line-cards can be persisted. One example is thermal sensors information from each of the line cards are stored in GLOBAL_STATE_DB. Control card can access this information to feed to the thermal-policy, fan algorithm etc.

#3117) Approach What is the motivation for this PR? Add new attribute modular_chassis which will be set true if DUT is modular chassis and False for other Add support to run tests on tests/platform_tests/test_cpu_memory_usage.py, tests/platform_tests/test_port_toggle.py on T2 chassis, change test_show_chassis_module to run duts per hwsku. Add new tests to verify thermal local and global state db on VoQ chassis introduced by PRs sonic-net/sonic-swss-common#395 and sonic-net/sonic-platform-daemons#101 How did you do it? modifications to current tests and new test file as below: tests/common/devices/sonic.py Add new attribute modular_chassis which can be used to skip tests only for modular chassis if DUT is not chassis possible values for attribute are True if DUT is part of modular chassis and False if not part of modular chassis tests/platform_tests/cli/test_show_chassis_module.py change test select one dut per hwsku instead of running on all DUTs tests/platform_tests/test_cpu_memory_usage.py change rand_one_dut_hostname to enum_rand_one_per_hwsku_hostname to test per hwsku. tests/platform_tests/test_port_toggle.py change rand_one_dut_hostname to enum_rand_one_per_hwsku_hostname to test per hwsku. tests/platform_tests/test_thermal_state_db.py Add new test for t2 chassis to verify thermal data in local state db for all thermal sensors Verify global state db in supervisor has data for all sensors from all modules in chassis How did you verify/test it? Validated the modified tests against a chassis .
