From 172e6a703041363decd6fc829542f33180c13beb Mon Sep 17 00:00:00 2001 From: Nick Brassel Date: Fri, 18 Jun 2021 09:10:06 +1000 Subject: Extensible split data sync (#11930) * Extensible split data sync capability through transactions. - Split common transport has been split up between the transport layer and data layer. - Split "transactions" model used, with convergence between I2C and serial data definitions. - Slave matrix "generation count" is used to determine if the full slave matrix needs to be retrieved. - Encoders get the same "generation count" treatment. - All other blocks of data are synchronised when a change is detected. - All transmissions have a globally-configurable deadline before a transmission is forced (`FORCED_SYNC_THROTTLE_MS`, default 100ms). - Added atomicity for all core-synced data, preventing partial updates - Added retries to AVR i2c_master's i2c_start, to minimise the number of failed transactions when interrupts are disabled on the slave due to atomicity checks. - Some keyboards have had slight modifications made in order to ensure that they still build due to firmware size restrictions. * Fixup LED_MATRIX compile. * Parameterise ERROR_DISCONNECT_COUNT. --- common_features.mk | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'common_features.mk') diff --git a/common_features.mk b/common_features.mk index 1a079a8df2..15637d7608 100644 --- a/common_features.mk +++ b/common_features.mk @@ -537,7 +537,11 @@ ifeq ($(strip $(SPLIT_KEYBOARD)), yes) # Determine which (if any) transport files are required ifneq ($(strip $(SPLIT_TRANSPORT)), custom) - QUANTUM_LIB_SRC += $(QUANTUM_DIR)/split_common/transport.c + QUANTUM_SRC += $(QUANTUM_DIR)/split_common/transport.c \ + $(QUANTUM_DIR)/split_common/transactions.c + + OPT_DEFS += -DSPLIT_COMMON_TRANSACTIONS + # Functions added via QUANTUM_LIB_SRC are only included in the final binary if they're called. # Unused functions are pruned away, which is why we can add multiple drivers here without bloat. ifeq ($(PLATFORM),AVR) -- cgit v1.2.3
