2010-09-07drm/i915: Enable MI_FLUSH on SandybridgeZhenyu Wang2-2/+7

2010-09-07drm/i915: Prevent double dpms onChris Wilson1-1/+4
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 <[email protected]>

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.)

2010-09-06vhost: fix attach to cgroups regressionMichael S. Tsirkin1-22/+57
Since 2.6.36-rc1, non-root users of vhost-net fail to attach if they are in any cgroups. The reason is that when qemu uses vhost, vhost wants to attach its thread to all cgroups that qemu has. But we got the API backwards, so a non-priveledged process (Qemu) tried to control the priveledged one (vhost), which fails. Fix this by switching to the new cgroup_attach_task_all, and running it from the vhost thread. Signed-off-by: Michael S. Tsirkin <[email protected]>
2010-09-05cgroups: fix API thinkoMichael S. Tsirkin2-5/+15
cgroup_attach_task_current_cg API that have upstream is backwards: we really need an API to attach to the cgroups from another process A to the current one. In our case (vhost), a priveledged user wants to attach it's task to cgroups from a less priveledged one, the API makes us run it in the other task's context, and this fails. So let's make the API generic and just pass in 'from' and 'to' tasks. Add an inline wrapper for cgroup_attach_task_current_cg to avoid breaking bisect. Signed-off-by: Michael S.
