All scripts and functions: Add DEBUG calling trace on console when CONFIG_DEBUG_OUTPUT is exported in board config -qemu-coreboot-*whiptail-tpm1(-hotp) boards have 'export CONFIG_DEBUG_OUTPUT=y' by default now 2023-02-18 12:58:43 -05:00
Add TRACE function tracing function to output on console when enabled - Add TRACE function tracing output under etc/functions, depending on CONFIG_ENABLE_FUNCTION_TRACING_OUTPUT enabled in board configs - Replace current DEBUG to TRACE calls in code, reserving DEBUG calls for more verbose debugging later on (output of variables etc) - add 'export CONFIG_ENABLE_FUNCTION_TRACING_OUTPUT=y' in qemu-coreboot(fb)whiptail-tpm1(-hotp) boards to see it in action 2023-02-20 11:01:17 -05:00			`TRACE "Under /bin/poweroff"`
Ensure recovery for failed default boot Should close #223 Added reboot and poweroff scripts using /proc/sysrq-trigger Also cleaned up the boot loop in generic-init 2017-07-22 14:57:46 -04:00
reboot, poweroff: Prepare TPM2 for shutdown TPM2 must be prepared for shutdown, or it may track an auth failure for dictionary attack prevention (per the spec, to prevent an attack by attempting to authenticate and then powering off the TPM before it can update the nonvolatile counter). Add tpmr shutdown to prepare for shutdown (no-op on TPM1). Invoke it from poweroff and reboot. Signed-off-by: Jonathon Hall <jonathon.hall@puri.sm> 2023-03-08 16:20:21 -05:00			`# Shut down TPM`
