This should fix incorrect reporting for systems with a dead or no battery. Additionally, handle error codes other than NO_HW_PRESENT by omitting the battery capacity display. LSI's supercap-based parts (CV series) report their data using the same interface as battery-based parts, except that they do not include the capacity stats (state of charge, cumulative charge cycles, etc.) PR: bin/160581 Modified: stable/8/usr.sbin/mfiutil/mfi_show.c Directory Properties: stable/8/usr.sbin/mfiutil/ (props changed) Modified: stable/8/usr.sbin/mfiutil/mfi_show.c ============================================================================== --- stable/8/usr.sbin/mfiutil/mfi_show.c Tue Oct 4 00:15:40 2011 (r225955) +++ stable/8/usr.sbin/mfiutil/mfi_show.c Tue Oct 4 00:29:10 2011 (r225956) @@ -141,7 +141,7 @@ show_battery(int ac, char **av) struct mfi_bbu_design_info design; struct mfi_bbu_status stat; uint8_t status; - int comma, error, fd; + int comma, error, fd, show_capacity; if (ac != 1) { warnx("show battery: extra arguments"); @@ -157,16 +157,17 @@ show_battery(int ac, char **av) if (mfi_dcmd_command(fd, MFI_DCMD_BBU_GET_CAPACITY_INFO, &cap, sizeof(cap), NULL, 0, &status) < 0) { - if (status == MFI_STAT_NO_HW_PRESENT) { - printf("mfi%d: No battery present\n", mfi_unit); - close(fd); - return (0); - } error = errno; warn("Failed to get capacity info"); close(fd); return (error); } + if (status == MFI_STAT_NO_HW_PRESENT) { + printf("mfi%d: No battery present\n", mfi_unit); + close(fd); + return (0); + } + show_capacity = (status == MFI_STAT_OK); if (mfi_dcmd_command(fd, MFI_DCMD_BBU_GET_DESIGN_INFO, &design, sizeof(design), NULL, 0, NULL) < 0) { @@ -192,10 +193,14 @@ show_battery(int ac, char **av) printf(" Model: %s\n", design.device_name); printf(" Chemistry: %s\n", design.device_chemistry); printf(" Design Capacity: %d mAh\n", design.design_capacity); - printf(" Full Charge Capacity: %d mAh\n", cap.full_charge_capacity); - printf(" Current Capacity: %d mAh\n", cap.remaining_capacity); - printf(" Charge Cycles: %d\n", cap.cycle_count); - printf(" Current Charge: %d%%\n", cap.relative_charge); + if (show_capacity) { + printf(" Full Charge Capacity: %d mAh\n", + cap.full_charge_capacity); + printf(" Current Capacity: %d mAh\n", + cap.remaining_capacity); + printf(" Charge Cycles: %d\n", cap.cycle_count); + printf(" Current Charge: %d%%\n", cap.relative_charge); + } printf(" Design Voltage: %d mV\n", design.design_voltage); printf(" Current Voltage: %d mV\n", stat.voltage); printf(" Temperature: %d C\n", stat.temperature);
