2010-03-31drm/radeon/kms/pm: fix segfault in clock codeAlex Deucher
Make sure we have a crtc assigned to the encoder before dereferencing it. Signed-off-by: Alex Deucher <alexdeucher@gmail.com>
2010-03-31drm/radeon/kms: expose thermal/fan i2c busesAlex Deucher
Look up i2c bus in the power table and expose it. You'll need to load a hwmon driver for any chips on the bus, this patch just exposes the bus. Signed-off-by: Alex Deucher <alexdeucher@gmail.com>
2010-03-15drm/radeon/kms: prepare for more reclocking operationsRafał Miłecki

2010-03-15drm/radeon/kms: switch to condition waiting for reclockingRafał Miłecki
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.

2010-02-23drm/radeon/kms: for downclocking non-mobility check PERFORMANCE stateRafał Miłecki
AtomBIOS tables on non-mobility GPU do not contain POWERSAVE/BATTERY. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-02-23drm/radeon/kms: simplify storing current and requested PM modeRafał Miłecki
We kept pointers to requested and current clock modes in every power state. That was useless, more /global/ pointers in power struct are enough. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-02-23[rfc] drm/radeon/kms: pm debugging check for vbl.Dave Airlie
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.

Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-02-09drm/radeon/kms: use wait queue (events) for VBLANK syncRafał Miłecki
This already simplifies code significally and makes it maintaible in case of adding memory reclocking plus voltage changing in future. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-02-09drm/radeon/kms: get_power_state early, not when processing IRQRafał Miłecki

2010-02-09drm/radeon/kms: use power states for dynamic reclockingAlex Deucher

2010-02-09drm/radeon/kms: add code to select power stateAlex Deucher
not hooked up yet. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-02-09drm/radeon/kms: add a power state type based on power state flagsAlex Deucher
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 Deucher
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>
2010-02-09drm/radeon/kms: add dynamic engine reclocking (V9)Rafał Miłecki
V2: reorganize functions, fix modesetting calls V3: rebase patch, use radeon's workqueue V4: enable on tested chipsets only, request VBLANK IRQs V5: enable PM on older hardware (IRQs, mode_fixup, dpms) V6: use separate dynpm module parameter V7: drop RADEON_ prefix, set minimum mode for dpms off V8: update legacy encoder call, fix order in rs600 IRQ V9: update compute_clocks call in legacy, not only DPMS_OFF Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
