Some LVDS connectors don't have a ddc bus, so reset the ddc bus to invalid before parsing the next connector to avoid using stale ddc bus data. Should fix fdo bug 28164. Signed-off-by:

The current initialisation code probes 'unsupported' AGP devices simply by calling its own probe function. It does not lock these devices or even check whether another driver is already bound to them. We must use the device core to manage this. So if the specific device id table didn't match anything and agp_try_unsupported=1, switch the device id table and call driver_attach() again. Signed-off-by:

SIS 760 is listed in the device tables for both amd64-agp and sis-agp. amd64-agp is apparently preferable since it has workarounds for some BIOS misconfigurations that sis-agp doesn't handle. Signed-off-by:

This patch is a combination of the previous two profile patches, but without the index bugs. It cleans up and fixes some issues with pm profile setup on r6xx chips. Some tables have different orderings for the power states, also, r600 only has 1 clock mode per power state. On desktop cards there are no battery modes, so the low and high power states are the same. For the low profile case, choose the lower clock mode. Signed-off-by:

- Separate dynpm and profile based power management methods. You can select the pm method by echoing the selected method ("dynpm" or "profile") to power_method in sysfs. - Expose basic 4 profile in profile method "default" - default clocks "auto" - select between low and high based on ac/dc state "low" - DC, low power mode "high" - AC, performance mode The current base profile is "default", but it should switched to "auto" once we've tested on more systems. Switching the state is a matter of echoing the requested profile to power_profile in sysfs. The lowest power states are selected automatically when dpms turns the monitors off in all states but default. - Remove dynamic fence-based reclocking for the moment. We can revisit this later once we have basic pm in. - Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure display side is initialized before pm. - Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume. - Remove dynpm module option. It's now selectable via sysfs. Signed-off-by: -

The lowest power states often cause display problems, so only enable them when all displays are off. Signed-off-by:

GUI idle interrupts don't seem to work terribly well on r500 and earlier, so let's use a fence instead. Signed-off-by:

Add two new sysfs attributes: - dynpm - power_state Echoing 0/1 to dynpm disables/enables dynamic power management. The driver scales the sclk dynamically based on the number of queued fences. dynpm only scales sclk dynamically in single head mode. Echoing x.y to power_state selects a static power state (x) and clock mode (y). This allows you to statically select a power state and clock mode. Selecting a static clock mode will disable dynpm.

- pm_misc() - handles voltage, pcie lanes, and other non clock related power mode settings. Currently disabled. Needs further debugging - pm_prepare() - disables crtc mem requests right now. All memory clients need to be disabled when changing memory clocks. This function can be expanded to include disabling fb access as well. - pm_finish() - enable active memory clients. Signed-off-by:

This also simplifies the code and enables reclocking with multiple heads active by tracking whether the power states are single or multi-head capable.
