git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes A couple of DP regression fixes, kepler memory reclocking fixes, and a fix for an annoying display issue that can pop up on resume. * 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: drm/nouveau/ram: fix test for gpio presence drm/nouveau/dp: workaround broken display drm/nouveau/dp: fix required link bandwidth calculations drm/nouveau/kms: restore fbcon after display has been resumed drm/nv50-/kms: pass a non-zero value for head to sor dpms methods drm/nouveau/fb: Prevent inlining of ramfuc_reg drm/gk104/ram: bash mpll bit 31 on
2014-07-08drm/nouveau/ram: fix test for gpio presenceBen Skeggs1-1/+1

2014-07-08drm/nouveau/dp: workaround broken displayBen Skeggs1-0/+1
The display in fdo#76483 pulses the hotplug line for link retraining after we cut power to the main link on the source, even while it's in D3. fdo#76483 Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-07-08drm/nouveau/kms: restore fbcon after display has been resumedBen Skeggs3-19/+12
Under some complicated circumstances (boot, suspend, resume, attach second display, suspend, resume, suspend, detach second display, resume, suspend, attach second display, resume), the fb_set_suspend() call can somehow result in a modeset being attempted before we're ready for it and things blow up in fun ways. Running display init first fixes the issue. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-07-08drm/nv50-/kms: pass a non-zero value for head to sor dpms methodsBen Skeggs1-1/+2
There's Apple machines out there which (probably completely arbitrarily) restrict each output path to a particular head. This causes us to not be able to locate the output data needed to power on/off the DP output correctly. We fix this by passing in a head index we know is valid (as opposed to "head 0").

2014-07-08drm/nouveau/fb: Prevent inlining of ramfuc_regStéphane Marchesin1-1/+1
When gcc 4.8 inlines this function, it eats up 16 bytes on the stack every time. Eventually we hit warnings because our stack grew too much: ramnve0.c:1383:1: error: the frame size of 1496 bytes is larger than 1024 bytes We fix this by preventing inlining for this function.

SOR_PWR has no effect to power-off DP links, unlike other SOR protocols. Instead, on the source side, we cut power to the lanes after having put the sink into D3. Link training takes care of everything required to bring it back again. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
