Testing on a Pi 5, the latest bootloader EEPROM from 2024-12-07 configures 8 NUMA nodes by default when there is no SDRAM_BANKLOW specified in its config.Don’t enter the SDRAM_BANKLOW setting in the EEPROM config.ok, how to disable NUMA?
However, I tested setting SDRAM_BANKLOW=-1 (i.e. minus one), and this appeared to do the trick:
Code:
andrew@tarmachan:~ $ vcgencmd bootloader_config[all]BOOT_ORDER=0xf146POWER_OFF_ON_HALT=1SDRAM_BANKLOW=-1Code:
