lib: sbi: Introduce an early console buffer for caching early prints

2024-07-24T06:48:41Z

The console device is registered by platform only in early_init() callback so any prints before this point will be lost. Introduce an early console buffer for caching prints before platform early_init(). For crashes before platform early_init(), users can simply dump the contents of the console_early_buffer[] string using a debugger. The relative address of the console_early_buffer[] string can be found using following two commands: CONSOLE_EARLY_FIFO_ADDR=`${CROSS_COMPILE}objdump -D \ build/platform/generic/firmware/fw_dynamic.elf | \ grep ":" | awk '{print $1}'` ${CROSS_COMPILE}objdump -R build/platform/generic/firmware/fw_dynamic.elf | \ grep $CONSOLE_EARLY_FIFO_ADDR | awk '{print $3}' Signed-off-by: Anup Patel Reviewed-By: Himanshu Chauhan

lib: Add SBIUnit testing macros and functions

2024-03-10T04:35:28Z

This patch introduces all of the SBIUnit macros and functions which can be used during the test development process. Also, it defines the 'run_all_tests' function, which is being called during the 'init_coldboot' right after printing the boot hart information. Also, add the CONFIG_SBIUNIT Kconfig entry in order to be able to turn the tests on and off. When the CONFIG_SBIUNIT is disabled, the tests and all related code is excluded completely on the compilation stage. Signed-off-by: Ivan Orlov Reviewed-by: Andrew Jones

lib: sbi_ecall: Add Kconfig option for each extension

2022-10-23T05:31:33Z

For each SBI extension, we: - Add a Kconfig option for it - Add the extension to sbi_ecall_exts only if the extension is enabled - Add the corresponding sbi_ecall_* object file only if the extension is enabled Special cases are as follows: - The legacy extensions are lumped together as one 'big' extension, as has always been the case in OpenSBI code. - The platform-defined vendor extensions are regarded as one extension. - The Base extension cannot be disabled. - sbi_ecall_replace implements multiple extensions, so it's not easy to avoid linking it in. Enable it always, and use #ifdef to disable/enable individual extensions. Signed-off-by: Vivian Wang Reviewed-by: Andrew Jones Reviewed-by: Anup Patel
