LVDS is the first output where dpms on/off and prepare/commit don't perfectly match. Now the idea behind this special case seems to be that for simple resolution changes on the LVDS we don't need to stop the pipe, because (at least on newer chips) we can adjust the panel fitter on the fly. There are a few problems with the current code though: - We still stop and restart the pipe unconditionally, because the crtc helper code isn't flexible enough. - We show some ugly flickering, especially when changing crtcs (this the crtc helper would actually take into account, but we don't implement the encoder->get_crtc callback required to make this work properly). So it doesn't even work as advertised. I agree that it would be nice to do resolution changes on LVDS (and also eDP) whithout blacking the screen where the panel fitter allows to do that. But imo we should implement this as a special case a few layers up in the mode set code, akin to how we already detect simple framebuffer changes (and only update the required registers with ->mode_set_base). Until this is all in place, make our lives easier and just rip it out. Also note that this seems to fix actual bugs with enabling the lvds output, see: http://lists.freedesktop.org/archives/intel-gfx/2012-July/018614.html Cc: Takashi Iwai <tiwai@suse.de> Cc: Giacomo Comes <comes@naic.edu> Acked-by: NChris Wilson <chris@chris-wilson.co.uk> Tested-by: NTakashi Iwai <tiwai@suse.de> Signed-Off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

The issue is that we stale data in the CPU caches, when we come to swap-out the object, the CPU may short-circuit the reads from those cacheline and so corrupt the context object. Secondary, leaving the context object as being marked in the CPU write domain whilst on the GPU active list is a bad idea and will throw warnings later. Note: Thanks to calling set_to_gtt_domain with write = false and not setting any gpu write domain when putting a context object onto the active list (when we switch away from it) the set_to_gtt_domain call won't block.

Setting dev_mapping (pointer to the address_space structure used for memory mappings) to the address_space of the first opener's inode and then failing if other openers come in through a different inode has a few restrictions that are eliminated by this patch. If we already have valid dev_mapping and we spot an opener with different i_node, we force its i_mapping pointer to the already established address_space structure (first opener's inode). This will make all mappings from drm device hang off the same address_space object. Some benefits (things that now work and didn't work before) of this patch are: * user space can mknod and use any number of device nodes and they will all work fine as long as the major device number is that of the drm module. * user space can even remove the first opener's device nodes and mknod the new one and the applications and windowing system will still work. * GPU drivers can safely assume that dev->dev_mapping is correct address_space and just blindly copy it into their (private) bdev.dev_mapping For reference, some discussion that lead to this patch can be found here: http://lists.freedesktop.org/archives/dri-devel/2012-April/022283.htmlSigned-off-by: NIlija Hadzic <ihadzic@research.bell-labs.com> Signed-off-by: NDave Airlie <airlied@redhat.com>

When we enable/disable the CPU backlight registers we can't forget to enable/disable the PCH backlight registers. Since we're using the CPU registers we should also unset the override bit. Fixes a regression on the following commit: drm/i915: properly enable the blc controller on the right pipe The commit just deleted the code that sets the PCH registers, so it was relying on the values set by the BIOS. I told my BIOS to boot on the DVI monitor instead of the LVDS panel, so I noticed the bug.

If we drop the breadcrumb request after a batch due to a signal for example we aim to fix it up at the next opportunity. In this case we emit a second batchbuffer with no waits upon the first and so no opportunity to insert the missing request, so we need to emit the missing flush for coherency. (Note that that invalidating the render cache is the same as flushing it, so there should have been no observable corruption.) Note that beside simply adding the missing flush, avoiding potential render corruption, this will also fix at least parts of the problem introduced by some funny interaction of these two commits: commit de2b9985 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Jul 4 22:52:50 2012 +0200 drm/i915: don't return a spurious -EIO from intel_ring_begin which allowed intel_ring_begin to return -ERESTARTSYS and commit cc889e0f Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Jun 13 20:45:19 2012 +0200 drm/i915: disable flushing_list/gpu_write_list which essentially disabled the flushing list. The issue happens when we submit a batch & emit it, but get interrupted (thanks to the first patch) while trying to emit the flush. On the next batch we still assume that the full gpu domain handling is in effect and hence compute the invalidate&flushing domains. But thanks to the 2nd patch we totally ignore these and only invalidate all gpu domains, presuming that any required flushes have been issued already. Which is wrong and eventually results in us updating the new write_domain values with the computed pending_write_domain values, which leaves an object with write_domain == 0 on the gpu_write_list. As soon as we try to unbind that object, things blow up. Fix this by emitting the missing flush according to the new ring->gpu_caches_dirty flag. Note that this does _not_ fix all the current cases where we end up with an object on the flushing_list that can't be flushed.

While debugging Haswell link train failures I observed that we never try the maximum voltage configuration more than once consecutively. We start the training, the monitor keeps telling us to increase the voltage, then when we reach the maximum we just go back to the start (because of the "memset" above "voltage_tries = 0"). When we reach this point, we keep alternating between the maximum and the minimum voltages until we give up. The DP spec suggests that we should try the same voltage 5 times before giving up. This patch makes us try the maximum voltage at least 5 times before going back to the minimum voltages. This patch does not fix any particular bug I'm aware of.
