From 7fb2616e249184e217f9818a7662596165710ea4 Mon Sep 17 00:00:00 2001 From: Frans Pop Date: Mon, 26 Oct 2009 08:39:01 +0100 Subject: acpi: thermal: display forced passive trip points in proc Users can force a passive trip point for a thermal zone that does not have _PSV defined in ACPI by setting the passive attribute in sysfs. It's useful to display such trip points in /proc/acpi/thermal_zone. .../TZ1/cooling_mode: .../TZ1/polling_frequency:polling frequency: 10 seconds .../TZ1/state:state: ok .../TZ1/temperature:temperature: 53 C .../TZ1/trip_points:critical (S5): 110 C .../TZ1/trip_points:passive (forced): 95 C And if not set (passive is 0): .../TZ1/trip_points:passive (forced): Signed-off-by: Frans Pop Acked-by: Zhang Rui Signed-off-by: Andrew Morton Signed-off-by: Len Brown --- drivers/acpi/thermal.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/drivers/acpi/thermal.c b/drivers/acpi/thermal.c index 65f6781..9073ada 100644 --- a/drivers/acpi/thermal.c +++ b/drivers/acpi/thermal.c @@ -1052,6 +1052,13 @@ static int acpi_thermal_trip_seq_show(struct seq_file *seq, void *offset) acpi_device_bid(device)); } seq_puts(seq, "\n"); + } else { + seq_printf(seq, "passive (forced):"); + if (tz->thermal_zone->forced_passive) + seq_printf(seq, " %i C\n", + tz->thermal_zone->forced_passive / 1000); + else + seq_printf(seq, "\n"); } for (i = 0; i < ACPI_THERMAL_MAX_ACTIVE; i++) { -- cgit v1.1
