2010-06-08drm/radeon/kms/pm: track current voltage (v2)Alex Deucher1-0/+1
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>
2010-06-08drm/radeon/kms/pm: add mid profileAlex Deucher1-2/+10
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.

2010-06-08drm/radeon/kms/pm: Misc fixesAlex Deucher1-16/+10
- don't rest the power state in pm_init() We already boot up to the default power state. Note this patch relies on: drm/radeon/kms/pm: patch default power state with default clocks/voltages on r6xx+ To make sure the default power state matches the boot up state. - In the pm resume path asic init will have set the power state back to the default so reset the tracking state values.

2010-06-08drm/radeon: fix PM on non-vram cards.Dave Airlie1-9/+0
PM attemps to unmap objects that aren't actually mapped into userspace ever, so just don't bother unmapping them at this point, since all you are doing is nothing. We should be making sure all access to these objects are locked in kernel space instead. In theory the VRAM gart table is already done, and both the shaders and stolen vga memory blocks are never accessed at runtime. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16127 Reported-by: Jure Repnic <jlp.bugs@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-05-18drm/radeon/kms/pm: rework power managementAlex Deucher1-245/+383
- 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>
2010-05-18drm/radeon/kms/pm: add support for no display power statesAlex Deucher1-12/+26

2010-05-18radeon: Use fences to gate entry to reclocking on <r600Matthew Garrett1-0/+8

2010-05-18radeon: Try harder to ensure we reclock in vblankMatthew Garrett1-1/+10
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>
2010-05-18radeon: Fix locking in power management pathsMatthew Garrett1-14/+4
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Make sure that we determine the correct PM state before transitionMatthew Garrett1-0/+3
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Stop the ttm workqueue while reclockingMatthew Garrett1-0/+3

2010-05-18radeon: Take drm struct_mutex over reclockingMatthew Garrett1-0/+10
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Unmap vram pages when reclockingMatthew Garrett1-0/+28
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: Matthew Garrett <mjg@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-05-18radeon: Unify PM entry pathsMatthew Garrett1-58/+32

2010-05-18drm/radeon/kms/pm: rework power managementAlex Deucher1-1/+138
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.

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.

2010-03-15drm/radeon/kms: switch to condition waiting for reclockingRafał Miłecki1-3/+5
We tried to implement interruptible waiting with timeout (it was broken anyway) which was not a good idea as explained by Andrew. It's possible to avoid using additional variable but actually it inroduces using more complex in-kernel tools. So simply add one variable for condition.

2010-02-23[rfc] drm/radeon/kms: pm debugging check for vbl.Dave Airlie1-0/+27
This patch adds a check on avivo chips to see if we are in the VBL region for the active crtcs when we trigger the engine change. I appear to have glitches locally on pm transistion (not sure all fixes are in yet) and this at least seems to be correct here, maybe others can test on systems with no glitches.

2010-02-09drm/radeon/kms: add a power state type based on power state flagsAlex Deucher1-1/+11
The idea is to flag a power state with a certain type and use that type to decide on what state to select. On r6xx+, we select a state and then transition between clock modes in that state. On pre-r6xx, we transition between states directly. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-02-09drm/radeon/kms: pull power mode info from bios tables (v3)Alex Deucher1-0/+38
The general idea is to validate the current hw state against the set of power states and select a power state based on that. This patch just pulls the power states from the bios and prints the information. It is not currently hooked up in the actual power management code. Hooking it up will require reworking the the current power state selection code and will be handled in a future patch. Additionally, we'd need to decide on some default lower power states for cards without power tables. v2 - increment state_index after checking for default state v3 - fix typo in pm init on pre-atom cards, handle pre-atom cards without x86 bioses Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
