CXL 3.0 Spec 8.2.9.8.3.3 defines Set Alert Configuration mailbox command.
This patchset adds support for the command to configure warning alert.
Example:
# ./cxl set-alert-config mem0 -L 30 --life-used-alert=on
{
"memdev":"mem0",
"ram_size":"1024.00 MiB (1073.74 MB)",
"alert_config":{
"life_used_prog_warn_threshold_valid":true,
"dev_over_temperature_prog_warn_threshold_valid":false,
"dev_under_temperature_prog_warn_threshold_valid":false,
"corrected_volatile_mem_err_prog_warn_threshold_valid":false,
"corrected_pmem_err_prog_warn_threshold_valid":false,
"life_used_prog_warn_threshold_writable":true,
"dev_over_temperature_prog_warn_threshold_writable":true,
"dev_under_temperature_prog_warn_threshold_writable":true,
"corrected_volatile_mem_err_prog_warn_threshold_writable":true,
"corrected_pmem_err_prog_warn_threshold_writable":true,
"life_used_crit_alert_threshold":75,
"life_used_prog_warn_threshold":30,
"dev_over_temperature_crit_alert_threshold":0,
"dev_under_temperature_crit_alert_threshold":0,
"dev_over_temperature_prog_warn_threshold":0,
"dev_under_temperature_prog_warn_threshold":0,
"corrected_volatile_mem_err_prog_warn_threshold":0,
"corrected_pmem_err_prog_warn_threshold":0
},
"serial":"0",
"host":"0000:0d:00.0"
}
cxl memdev: cmd_set_alert_config: set alert configuration 1 mem
The implementation is based on the 'ndctl-inject-smart'. Variable and function
names are aligned with the implementation of 'Get Alert Configuration'.
