We don't know how to enable it safely, especially as outputs turn on and off. When disabling LP1 we also need to make sure LP2 and 3 are already disabled.

2010-09-09drm/i915: Double check that the wait_request is not pending before warningChris Wilson1-7/+15
If we are busy, then we may have woken up the wait_request handler but not yet serviced it before the hang check fires. So in hang check, double check that the i915_gem_do_wait_request() is still pending the wake-up before declaring all hope lost. Fixes regression with e78d73b16bcde921c9cf458d2e4de8e4fc2518f3.

This reverts commit b9421ae8f30958deea98d71477b4a77a066856b4. This warning was so prelevant, even for apparently working machines, that it was just causing fear, anxiety and panic. The root cause still remains, so we will add some better debugging when we focus on fixing it.

This reverts commit 0f3ee801b332d6ff22285386675fe5aaedf035c3. Enabling LVDS on pipe A was causing excessive wakeups on otherwise idle systems due to i915 interrupts.

Arguably this is a bug in drm-core in that we should not be called twice in succession with DPMS_ON, however this is still occuring and we see FDI link training failures on the second call leading to the occassional blank display.

2010-09-07drm/i915: Avoid pageflipping freeze when we miss the flip prepare interruptSimon Farnsworth4-12/+113
When we miss the flip prepare interrupt, we never get into the software state needed to restart userspace, resulting in a freeze of a full-screen OpenGL application (such as a compositor). Work around this by checking DSPxSURF/DSPxBASE to see if the page flip has actually happened. If it has, do the work we would have done when the flip prepare interrupt comes in. Also, add debugfs information to tell us what's going on (based on the patch from Chris Wilson attached to bugs.fdo bug #29798).

2010-09-07drm/i915: Tightly scope intel_encoder to prevent invalid useChris Wilson1-13/+12
We reset intel_encoder for every matching encoder whilst iterating over the encoders attached to this crtc when changing mode. As such in a cloned configuration intel_encoder may not correspond to the correct is_edp encoder. By scoping intel_encoder to the loop, not only is the compiler able to spot this mistake, we also improve readiability for ourselves. [It might not be a mistake, within this function it is unclear as to whether it is permissable for eDP to be cloned...] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-09-06drm/i915: overlay on gen2 can't address above 1GDaniel Vetter1-0/+4
So set the coherent dma mask accordingly. This dma mask is only used for physical objects, so it won't really matter allocation-wise. Now this never really surfaced because sane 32bit kernels only have 1G of lowmem. But some eager testers (distros?) still carry around the patch to adjust lowmem via a kconfig option. And the kernel seems to favour high allocations on boot-up, hence the overlay blowing up reliably. Because the patch is tiny and nicely shows how broken gen2 is it's imho worth to merge despite the fact that mucking around with the lowmem/ highmem division is (no longer) supported.

2010-09-07drm: Do not force 1024x768 modes on unknown connectorsChris Wilson1-4/+3
Only fallback to a set of default modes on a connector iff that connector is known to be connected. The issue occurs that with limited hardware which cannot probe a connector and so reports the connector status as unknown will then attempt to retrieve the modes for it during drm_helper_probe_single_connector_modes(). Should that fail, the helper then generates a default set which fools the fb_helper and causes havoc with the console and beyond.

2010-09-07drm/kms: Add a module parameter to disable pollingChris Wilson1-2/+15
Polling for a VGA device on an old system can be quite expensive, causing latencies on the order of 600ms. As we hold the mode mutex for this time and also need the same mutex to move the cursor, we trigger a user-visible stall. The real solution would involve improving the granulatity of the locking and so perhaps performing some of the probing not under the lock or some other updates can be done under different locks. Also reducing the cost of probing for a non-existent monitor would be worthwhile. However, exposing a parameter to disable polling is a simple workaround in the meantime. In order to accommodate users turning polling on and off at runtime, the polling is potentially re-enabled on every probe. This is coupled to the user calling xrandr, which seems to be a vaild time to reset the polling timeout since the information on the connection has just been updated. (The presumption being that all connections are probed in a single xrandr pass, which is currently valid.)
