drm/radeon/kms: add trivial debugging for voltage agd5f: rebased Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms/r600+: use voltage from requested clock mode (v3) This fixes FDO bug #28375, it's kind of regression, so quite important to have it for .35. V2: Fix on RV770+ as well. All other chipsets have only one clock mode per state. V3: I'm out of luck today. Grepped for voltage in r*.c and missed evergreen. agd5f: rebased Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms/pm: track current voltage (v2) track the current voltage level and avoid setting it if the requested voltage is already set. v2: check voltage type before checking current voltage Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms/pm: add mid profile This adds an additional profile, mid, to the pm profile code which takes the place of the old low profile. The default behavior remains the same, e.g., auto profile now selects between mid and high profiles based on power source, however, you can now manually force the low profile which was previously only available as a dpms off state. Enabling the low profile when the displays are on has been known to cause display corruption in some cases.

drm/radeon/kms/pm: add support for SetVoltage cmd table (V2) - This enables voltage adjustment on r6xx+ and certain r5xx asics. - Voltage drop support is already available for most r1xx-r5xx asics. V2: endian fix for voltage table. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms/pm/r600: select the mid clock mode for single head low profile This saves some more power at the expense of performance. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms/pm: fix r6xx+ profile setup 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.

drm/radeon/kms/pm: rework power management - 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: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms/pm: add support for no display power states The lowest power states often cause display problems, so only enable them when all displays are off. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms: more pm fixes - disable gui idle interrupt use Seems to hang some r5xx chips - move vbl range check into existing vbl check function in radeon_pm.c - disable crtc mc acccess for the whole reclocking process Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
radeon: Try harder to ensure we reclock in vblank The vblank interrupt on r600 doesn't seem to be especially reliable, so perform some sanity checks before the actual reclock. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
radeon: Enable memory reclockong on r600 With luck, dynamic memory reclocking on r600 should be stable with the previous patches. Enable it. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
drm/radeon/kms/pm: rework power management 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.

drm/radeon/kms/pm: add additional asic callbacks - 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.

drm/radeon/kms/pm: add asic specific callbacks for getting power state (v2) This also simplifies the code and enables reclocking with multiple heads active by tracking whether the power states are single or multi-head capable. Eventually, we will want to select a power state based on external factors (AC/DC state, user selection, etc.).

drm/radeon/kms: add support for gui idle interrupts (v4) 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.
