hwmon: (coretemp) Skip duplicate CPU entries

2010-08-02T17:18:49Z

commit d883b9f0977269d519469da72faec6a7f72cb489 upstream. On hyper-threaded CPUs, each core appears twice in the CPU list. Skip the second entry to avoid duplicate sensors. Signed-off-by: Jean Delvare Acked-by: Huaxu Wan Signed-off-by: Greg Kroah-Hartman

hwmon: (coretemp) Properly label the sensors

2010-08-02T17:18:49Z

commit 3f4f09b4be35d38d6e2bf22c989443e65e70fc4c upstream. Don't assume that CPU entry number and core ID always match. It worked in the simple cases (single CPU, no HT) but fails on multi-CPU systems. Signed-off-by: Jean Delvare Acked-by: Huaxu Wan Signed-off-by: Greg Kroah-Hartman

hwmon: (coretemp) Add missing newline to dev_warn() message

2010-04-01T22:52:29Z

commit 4d7a5644e4adfafe76c2bd8ee168e3f3b5dae3a8 upstream. Add missing newline to dev_warn() message string. This is more of an issue with older kernels that don't automatically add a newline if it was missing from the end of the previous line.

coretemp: recognize Nehalem CPUs

Add in the CPUID for Nehalem chips. Signed-off-by: Darrick J. Wong Cc: Kent Liu Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

hwmon: (coretemp) Add Penryn CPU to coretemp

2008-02-18T03:08:37Z

This patch adds support for family 0x17, which has Penryn Core. It should also cover the 8 cores Xeons. Can someone test please? I think it should work. Signed-off-by: Rudolf Marek Acked-by: Jean Delvare Signed-off-by: Mark M. Hoffman

hwmon: (coretemp) Add TjMax detection for mobile CPUs

2008-02-18T02:57:28Z

Following patch will finally solve the detection of Intel Mobile CPUs which share same CPUID with Desktop/Server CPUs. We need this information to test some bit so we know if TjMax is 100C or 85C. Intel claims this works for mobiles only, respect that and set for desktops the TjMax to 100C. Intel provided some table on their wiki based on my chat with them at: http://softwarecommunity.intel.com/isn/Community/en-US/forums/30247249/ShowThread.aspx#30247249 Signed-off-by: Rudolf Marek Signed-off-by: Mark M.

hwmon: (coretemp) fix section mismatch warning

2008-02-17T16:26:55Z

Fix following warning: WARNING: vmlinux.o(.text+0xebfd04): Section mismatch in reference from the function coretemp_cpu_callback() to the function .cpuinit.text:coretemp_device_add() coretemp_cpu_callback() are only used inside a HOTPLUG_CPU block so annotate it __cpuinit. The notifier referencing the function are annotated __refdata to silence warning from the exit function. The unregister function do not use the embedded pointer but clears the variable so the annotation is OK. Signed-off-by: Sam Ravnborg Signed-off-by: Mark M. Hoffman

hwmon: (coretemp) Add maximum cooling temperature readout

2008-02-17T15:21:39Z

Following patch will add reporting of maximum temperature, at which all fans should spin full speed. It may be non-physical temperature on Desktop/Server CPUs. Signed-off-by: Rudolf Marek Acked-by: Jean Delvare Signed-off-by: Mark M. Hoffman

HWMON: coretemp, suspend fix

2007-12-04T06:35:32Z

It's not permitted to unregister a device after devices have been suspended. It causes deadlocks to appear on systems with coretemp hwmon loaded. To avoid this, we can make coretemp_cpu_callback() do nothing if the _FROZEN bit is set in action. Also, in other cases it's generally too late to unregister the coretemp device if the CPU is already dead, so it should be unregistered on CPU_DOWN_PREPARE. Signed-off-by: Rafael J.

x86: convert cpuinfo_x86 array to a per_cpu array

2007-10-19T18:35:04Z

cpu_data is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpus. When NR_CPU count is raised to 4096 the size of cpu_data becomes 3,145,728 bytes. These changes were adopted from the sparc64 (and ia64) code. An additional field was added to cpuinfo_x86 to be a non-ambiguous cpu index. This corresponds to the index into a cpumask_t as well as the per_cpu index. It's used in various places like show_cpuinfo(). cpu_data is defined to be the boot_cpu_data structure for the NON-SMP case.
