* i7300_idle: allow testing on i5000-series hardware w/o re-compileLen Brown2009-05-281-1/+5
| | | | | | | | | | | | | | | | | | | | | | Testing the i7300_idle driver on i5000-series hardware required an edit to i7300_idle.h to "#define SUPPORT_I5000 1" and a re-build of both i7300_idle and ioat_dma. Replace that build-time scheme with a load-time module parameter: "7300_idle.forceload=1" to make it easier to test the driver on hardware that while not officially validated, works fine and is much more commonly available. By default (no modparam) the driver will continue to load only on the i7300. Note that ioat_dma runs a copy of i7300_idle's probe routine to know to reserve an IOAT channel for i7300_idle. This change makes ioat_dma do that always on the i5000, just like it does on the i7300. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Andrew Henroid <andrew.d.henroid@intel.com>

* i7300_idle: Disable ioat channel only on platforms where ile driver can loadVenki Pallipadi2008-10-241-70/+2
| | | | | | | | | Based on input from Andi Kleen: share the platform detection code with ioat_dma and disable the channel in dma engine only for specific platforms. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* i7300_idle driver v1.55Andy Henroid2008-10-213-0/+692
The Intel 7300 Memory Controller supports dynamic throttling of memory which can be used to save power when system is idle. This driver does the memory throttling when all CPUs are idle on such a system. Refer to "Intel 7300 Memory Controller Hub (MCH)" datasheet for the config space description.
