* hwmon: Make PCI device ids constantMárton Németh2010-01-105-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: (coretemp) Fix TjMax for Atom N450/D410/D510 CPUsYong Wang2010-01-102-3/+15
| | | | | | | | | | | The max junction temperature of Atom N450/D410/D510 CPUs is 100 degrees Celsius. Since these CPUs are always coupled with Intel NM10 chipset in one package, the best way to verify whether an Atom CPU is N450/D410/D510 is to check the host bridge device.

* hwmon: (asus_atk0110) Add debugfs interfaceLuca Tettamanti2010-01-101-0/+191
| | | | | | | | | | | Expose the raw GGRP/GITM interface via debugfs. The hwmon interface is reverse engineered and the driver tends to break on newer boards... Using this interface it's possible to poke directly at the ACPI methods without the need to recompile, reducing the guesswork and the round trips needed to support a new revision of the interface.

Although this is against the PCI specification, we can handle it quite easily by allowing drivers to define arbitrary D3 delays for devices known to require extra time for switching power states. Introduce additional field d3_delay in struct pci_dev and use it to store the value of the device's D0->D3 delay, in miliseconds. Make the PCI PM core code use the per-device d3_delay unless pci_pm_d3_delay is greater (in which case the latter is used). [This also allows the driver to specify d3_delay shorter than the 10 ms required by the PCI standard if the device is known to be able to handle that.] Make the sky2 driver set d3_delay to 150 for devices handled by it.

As reported by http://bugzilla.kernel.org/show_bug.cgi?id=14485, this dump will cause hang problem on some machine. If something really needs this kind of full registers dump, that could be done within intel-gpu-tools.

Instead, use the G4X DPLL calculator, which does a better job at it. So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS on ironlake. At the same time to consider the dpll setting for display port, we add the display port DPLL limit on ironlake, which will directly use the function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.

So remove this code altogether. I'm reworking it now to do the right thing, but the only bit it will share is the VBT check for whether reclocking is supported, so I'm leaving that bit.

The buffer passed in to the new ioctl includes a new relocation type to indicate whether a given object needs a fence register assigned for the command buffer in question. Compatibility with the existing execbuf ioctl is implemented in terms of the new code, preserving the assumption that fence registers are required for pre-965 rendering commands.
