* hwmon: Make PCI device ids constantMárton Németh2010-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The id_table field of the struct pci_driver is constant in <linux/pci.h> so it is worth to make pci_device_id also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // </smpl> Signed-off-by: Márton Németh <nm127@freemail.hu> Cc: Julia Lawall <julia@diku.dk> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (k8temp) Fix temperature reporting for (most) K8 RevG CPUsAndreas Herrmann2009-01-151-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Current Temperature for K8 RevG desktop CPUs is a "normalized value" which can be below ambient temperature. As a consequence lots of RevG systems report temperatures like: $ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +17 C Core0 Temp: +3 C Core1 Temp: +21 C Core1 Temp: +5 C being quite below ambient temperature. There are even reports of negative temperature values. This patch corrects the temperature reporting of k8temp for RevG desktop CPUs.

* hwmon: (k8temp) Fix wrong sensor selection for AMD K8 RevF/RevG CPUsAndreas Herrmann2009-01-151-0/+9
| | | | | | | | | | | | | Meaning of ThermSenseCoreSel bit was inverted beginning with K8 RevF. That means with current driver temp1/temp2 belong to core 1 and temp3/temp4 belong to core 0 on a K8 RevF/RevG CPU. This patch ensures that temp1/temp2 always belong to core 0 and temp3/temp4 to core 1 for all K8 revisions.

* hwmon: (k8temp) Warn about fam F rev F errataAndreas Herrmann2009-01-151-7/+22
| | | | | | | | | | | | | | | | | | | | Add warning about wrong CPU temperature readouts on all fam F rev F. The allowed combinations of processors ensure that all processors in a multisocket system have similar characteristics, e.g. (1) provide temperature sensor interface (>=RevC && <RevF) (2) are affected by erratum #141 (>=RevF) Thus it is sufficient to check the revision of the boot CPU. For "mixed silicon support" refer to "Revision Guide for AMD Athlon 64 and AMD Opteron Processors" (RevA-E) and "Revision Guide for AMD NPT Family 0Fh Processors" (RefF-G).
