* drm/i915: Remove dead KMS encoder save/restore code.Eric Anholt2010-04-1212-643/+4
| | | | | | | This was brought over from UMS, and used for a while until we decided that drm_helper_resume_force_mode was easier and more reliable, since it didn't require duplicating all the code deleted here. We just forgot to delete all that junk for a while.
* drm/i915: change intel_ddc_get_modes() function parametersZhenyu Wang2010-04-098-35/+26
| | | | | | | | | | | | | | | | This one replaces original param for intel_ddc_get_modes() with DRM connector and i2c bus adapter instead. With explicit params, we won't require that a single driver structure must hold connector and DDC bus reference, which ease the conversion to splitted encoder/ connector model. It also clears up for some cases that we would steal other DDC bus for mode probe, like VGA analog DDC probe for DVI-I. Also it fixed a bug in old DVI-I probe handling, that failed to restore origin analog GPIO port. Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
* drm/i915: passing drm connector param for load detectionZhenyu Wang2010-04-094-7/+14
| | | | | | | | | | | In load detection, connector's encoder assignment must be kept consistent for proper mode setting, and this makes connector as explicit parameter for load detect function to not require single data structure to hold both encoder and connector reference, ease the transition for splitted encoder/connector model.

Sometimes the TV will be misdetected as the following two cases: - TV is misdetected on some laptops. e.g. There is no TV connector port or no TV is attached. But the TV is shown as connected. - TV connector type is misdetected. e.g. the component TV is attached, but the TV is shown as S-video type. According to the hardware requirement, the TV sense state bits of TV DAC register should be cleared to zero on Cantiga platfrom. https://bugzilla.kernel.org/show_bug.cgi?id=14792 Cc: Stable Team <stable@kernel.org> Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Tested-by: Santi <santi@agolina.net> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>

* drm/i915: Rename intel_output to intel_encoder.Eric Anholt2010-03-2511-663/+663
| | | | | | | | | | | | | | | | | | The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors. This patch is produced by sed s/intel_output/intel_encoder/ over the driver. Signed-off-by: Eric Anholt <eric@anholt.net>

| | | | | | | | | | | I've been getting more and more quirk reports about this. It seems clear at this point that other OSes are not using this for determining whether the integrated panel should be turned on, and it is not reliable for doing so.

* drm/intel: fix up set_tiling for untiled->tiled transitionDaniel Vetter2010-03-181-2/+5
| | | | | | | | | | | | | | | | | | | | | | Bug introduced in commit 10ae9bd25acf394c8fa2f9d795dfa9cec4d19ed6 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Feb 1 13:59:17 2010 +0100 drm/i915: blow away userspace mappings before fence change The problem is that when there's no fence reg assigned and the object is mapped at a fenceable offset in the gtt, the userspace mappings won't be torn down. Which happens on untiled->tiled transition quite often on 4th gen and later because there fencing does not have any special alignment constraints (as opposed to 2nd and 3rd gen on which I've tested the original commit).

Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method ATI/ATI - some ASUS - use ATPX ACPI Method Intel/Nvidia - - use _DSM ACPI method Nvidia/Nvidia - - use _DSM ACPI method. TODO: This patch adds support for the ATPX method and initial bits for the _DSM methods that need to written by someone with access to the hardware. Add a proper non-debugfs interface - need to get some proper testing first. v2: add power up/down support for both devices on W500 puts i915/radeon into D3 and cuts power to radeon. v3: redo probing methods, no DMI list, drm devices call to register with switcheroo, it tries to find an ATPX method on any device and once there is two devices + ATPX it inits the switcher. v4: ATPX msg handling using buffers - should work on more machines v5: rearchitect after more mjg59 discussion - move ATPX handling to radeon driver. v6: add file headers + initial nouveau bits (to be filled out). v7: merge delayed switcher code. v8: avoid suspend/resume of gpu that is off v9: rearchitect - mjg59 is always right. - move all ATPX code to radeon, should allow simpler DSM also proper ATRM handling v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv v11: fix bug in resuming Intel for 2nd time. v12: start fixing up nvidia code blindly. v13: blindly guess at finishing nvidia code v14: remove radeon audio hacks - fix up intel resume more like upstream v15: clean up printks + remove unnecessary igd/dis pointers mount debugfs /sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected + 2 cards.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It would be good to disable the LVDS port when we shut down the panel to save power. We haven't done so until now because we had trouble getting the right LVDS parameters from the BIOS. I think we're past that now, so enabling and disabling the port should be safe, though it would probably be made cleaner with some additional changes to the display code, where we also bang on the LVDS reg to set the pairing correctly etc. Seems to save a bit of power (up to 300mW in my basic wattsup meter testing).

| * | drm/i915: Record batch buffer following GPU errorChris Wilson2010-02-225-7/+326
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to improve our diagnostic capabilities following a GPU hang and subsequent reset, we need to record the batch buffer that triggered the error. We assume that the current batch buffer, plus a few details about what else is on the active list, will be sufficient -- at the very least an improvement over nothing. The extra information is stored in /debug/dri/.../i915_error_state following an error, and may be decoded using intel_gpu_tools/tools/intel_error_decode. v2: Avoid excessive work under spinlocks. v3: Include ringbuffer for later analysis. v4: Use kunmap correctly and record more buffer state. v5: Search ringbuffer for current batch buffer v6: Use a work fn for the impossible IRQ error case. v7: Avoid non-atomic paths whilst in IRQ context.
