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:

We need to handle the ring while we've already locked it, so split out the allocation and commit functions in order to allow them to be used. Signed-off-by:

The vblank interrupt on r600 doesn't seem to be especially reliable, so perform some sanity checks before the actual reclock. Signed-off-by:

The ttm code could take vram_mutex followed by cp_mutex, while the reclocking code would do the reverse. Hilarity could ensue. Signed-off-by:

We need to choose the correct PM state to transition into before starting the actual change. Call radeon_get_power_state() at the top of the clock setting to do so. Signed-off-by:

We want to be able to prevent the delayed workqueue from changing state while we're reclocking, so add an API to block and unblock it. Signed-off-by:

We need to block the drm core from doing anything that may touch our vram during reclock, so take the drm mutex for the duration. Signed-off-by:

Touching vram while the card is reclocking can lead to lockups. Unmap any pages that could be touched by the CPU and block any accesses to vram until the reclocking is complete. Signed-off-by:

There's a moderate amount of effort involved in setting the card up for clock transitions, so unify the codepaths to make it easier to implement. 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.

Useful for certain power management operations. You need to wait for the GUI engine (2D, 3D, CP, etc.) to be idle before changing clocks or adjusting engine parameters. (v2) Fix gui idle enable on pre-r6xx asics (v3) The gui idle interrrupt status bit is permanently asserted on pre-r6xx chips, but the interrrupt is still generated. workaround it in the driver.
