From 21a8122ad38c60d73fe5dc51051414c3564d174a Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 2 Jul 2010 12:58:16 -0400 Subject: drm/radeon/kms: add support for internal thermal sensors (v3) rv6xx/rv7xx/evergreen families supported; older asics did not have an internal thermal sensor. Note, not all oems use the internal thermal sensor, so it's only exposed in cases where it is used. Note also, that most laptops use an oem specific ACPI solution for GPU thermal information rather than using the internal thermal sensor directly. v2: export millidegrees celsius, use hwmon device properly. v3: fix Kconfig Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie --- drivers/gpu/drm/radeon/r600d.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'drivers/gpu/drm/radeon/r600d.h') diff --git a/drivers/gpu/drm/radeon/r600d.h b/drivers/gpu/drm/radeon/r600d.h index 59c1f8793e60..23205f032872 100644 --- a/drivers/gpu/drm/radeon/r600d.h +++ b/drivers/gpu/drm/radeon/r600d.h @@ -239,6 +239,11 @@ #define GRBM_SOFT_RESET 0x8020 #define SOFT_RESET_CP (1<<0) +#define CG_THERMAL_STATUS 0x7F4 +#define ASIC_T(x) ((x) << 0) +#define ASIC_T_MASK 0x1FF +#define ASIC_T_SHIFT 0 + #define HDP_HOST_PATH_CNTL 0x2C00 #define HDP_NONSURFACE_BASE 0x2C04 #define HDP_NONSURFACE_INFO 0x2C08 -- cgit v1.2.3
