into drm-fixes The set_need_resched() removal fix and yet another fix in ttm_bo_move_memcpy(). * 'ttm-fixes-3.13' of git://people.freedesktop.org/~thomash/linux: drm/ttm: Remove set_need_resched from the ttm fault handler drm/ttm: Don't move non-existing data
2013-11-20drm/ttm: Remove set_need_resched from the ttm fault handlerThomas Hellstrom1-1/+3
Addresses "[BUG] completely bonkers use of set_need_resched + VM_FAULT_NOPAGE". In the first occurence it was used to try to be nice while releasing the mmap_sem and retrying the fault to work around a locking inversion. The second occurence was never used. There has been some discussion whether we should change the locking order to mmap_sem -> bo_reserve. This patch doesn't address that issue, and leaves that locking order undefined. The solution that we release the mmap_sem if tryreserve fails and wait for the buffer to become unreserved is something we want in any case, and follows how the core vm system waits for pages to be come unlocked while releasing the mmap_sem. The code also outlines what needs to be changed if we want to establish the locking order as mmap_sem -> bo::reserve. One slight issue that remains with this code is that the fault handler might be prone to starvation if another thread countinously reserves the buffer. IMO that usage pattern is highly unlikely.

2013-11-10Merge tag 'bdw-stage1-2013-11-08-v2' of ↵Dave Airlie2-0/+29
git://people.freedesktop.org/~danvet/drm-intel into drm-next So here's the Broadwell pull request. From a kernel driver pov there's two areas with big changes in Broadwell: - Completely new enumerated interrupt bits. On the plus side it now looks fairly unform and sane. - Completely new pagetable layout. To ensure minimal impact on existing platforms we've refactored both the irq and low-level gtt handling code a lot in anticipation of the bdw push. So now bdw enabling in these areas just plugs in a bunch of vfuncs. Otherwise it's all fairly harmless adjusting of switch cases and if-ladders to shovel bdw into the right blocks. So minimized impact on existing platforms. I've also merged the bdw-stage1 branch into our -nightly integration branch for the past week to make sure we don't break anything. Note that there's still quite a flurry or patches floating around, but I've figured I'll push this out. I plan to keep the bdw fixes separate from my usual -fixes stream so that you can reject them easily in case it still looks like too much churn. Also, bdw is for now hidden behind the preliminary hw enabling module option. So there's no real pressure to get follow-up patches all into 3.13. * tag 'bdw-stage1-2013-11-08-v2' of git://people.freedesktop.org/~danvet/drm-intel: (75 commits) drm/i915: Mask the vblank interrupt on bdw by default drm/i915: Wire up cpu fifo underrun reporting support for bdw drm/i915: Optimize gen8_enable|disable_vblank functions drm/i915: Wire up pipe CRC support for bdw drm/i915: Wire up PCH interrupts for bdw drm/i915: Wire up port A aux channel drm/i915: Fix up the bdw pipe interrupt enable lists drm/i915: Optimize pipe irq handling on bdw drm/i915/bdw: Take render error interrupt out of the mask drm/i915/bdw: Add BDW PCH check first drm/i915: Use hsw_crt_get_config on BDW drm/i915/bdw: Change dp aux timeout to 600us on DDIA drm/i915/bdw: Enable trickle feed on Broadwell drm/i915/bdw: WaSingleSubspanDispatchOnAALinesAndPoints drm/i915/bdw: conservative SBE VUE cache mode drm/i915/bdw: Limit SDE poly depth FIFO to 2 drm/i915/bdw: Sampler power bypass disable ddrm/i915/bdw: Disable centroid pixel perf optimization drm/i915/bdw: BWGTLB clock gate disable drm/i915/bdw: Implement edp PSR workarounds ...

2013-11-06drm: Push latency sensitive bits of vblank scanoutpos timestamping into kms ↵Mario Kleiner1-2/+8
drivers. A change in locking of some kms drivers (currently intel-kms) make the old approach too inaccurate and also incompatible with the PREEMPT_RT realtime kernel patchset. The driver->get_scanout_position() method of intel-kms now needs to aquire a spinlock, which clashes badly with the former preempt_disable() calls in the drm, and it also introduces larger delays and timing uncertainty on a contended lock than acceptable. This patch changes the prototype of driver->get_scanout_position() to require/allow kms drivers to perform the ktime_get() system time queries which go along with actual scanout position readout in a way that provides maximum precision and to return those timestamps to the drm. kms drivers implementations of get_scanout_position() are asked to implement timestamping and scanoutpos readout in a way that is as precise as possible and compatible with preempt_disable() on a PREMPT_RT kernel. A driver should follow this pattern in get_scanout_position() for precision and compatibility: spin_lock...(...); preempt_disable_rt(); // On a PREEMPT_RT kernel, otherwise omit. if (stime) *stime = ktime_get(); ... Minimum amount of MMIO register reads to get scanout position ... ... no taking of locks allowed here! ... if (etime) *etime = ktime_get(); preempt_enable_rt(); // On PREEMPT_RT kernel, otherwise omit. spin_unlock...(...); v2: Fix formatting of new multi-line code comments.

into drm-next drm/tegra: Changes for v3.13-rc1 The biggest part of the changes is the decoupling of the host1x and DRM drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra from whence it came. There is a lot of cleanup as well, and the drivers can now be properly unloaded and reloaded. HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen. gr2d support was extended to Tegra114 and the gr3d driver that has been in the works for quite some time finally made it in. All pieces to run an OpenGL driver on top of an upstream kernel are now available. Support for syncpoint bases was added by Arto Merilainen. This is useful for synchronizing between command streams from different engines such as gr2d and gr3d. Erik Faye-Lund and Wei Yongjun contributed various small fixes.

2013-10-31drm/tegra: Move subdevice infrastructure to host1xThierry Reding1-0/+1
The Tegra DRM driver currently uses some infrastructure to defer the DRM core initialization until all required devices have registered. The same infrastructure can potentially be used by any other driver that requires more than a single sub-device of the host1x module. Make the infrastructure more generic and keep only the DRM specific code in the DRM part of the driver. Eventually this will make it easy to move the DRM driver part back to the DRM subsystem.

git://ftp.arm.linux.org.uk/~rmk/linux-cubox into drm-next This adds support for the Armada 510 display subsystem found on the Marvell Dove devices. This IP is re-used across several different Marvell SoCs with various tweaks, and this driver has been structured to allow the other IPs to re-use the bulk of this code; further work in this area is expected from interested parties. This has been extensively tested on the SolidRun Cubox platform and appears to work well there. [airlied: update for api changes merged previous to this]
2013-10-22drm/sysfs: sort out minor and connector device object lifetimes.Dave Airlie2-2/+2
So drm was abusing device lifetimes, by having embedded device structures in the minor and connector it meant that the lifetime of the internal drm objects (drm_minor and drm_connector) were tied to the lifetime of the device files in sysfs, so if something kept those files opened the current code would kfree the objects and things would go downhill from there. Now in reality there is no need for these lifetimes to be so intertwined, especailly with hotplugging of devices where we wish to remove the sysfs and userspace facing pieces before we can unwind the internal objects due to open userspace files or mmaps, so split the objects out so the struct device is no longer embedded and do what fbdev does and just allocate and remove the sysfs inodes separately.

2013-10-01drm: Remove clock_index from struct drm_display_modeDamien Lespiau1-1/+0
This field was only accessed by the nouveau driver, but never set. So concluded we can rid of this one.

2013-10-01drm: Make exposing stereo modes a per-connector opt-inDamien Lespiau1-0/+2
Just like with interlaced or double scan modes, make stereo modes a per-connector opt-in to give a chance to driver authors to make it work before enabling it.

2013-10-01drm: Make drm_match_cea_mode() return the underlying 2D VIC for 3d modesDamien Lespiau1-1/+1
When scanning out a stereo mode, the AVI infoframe vic field has to be the underlyng 2D VIC. Before that commit, we weren't matching the CEA mode because of the extra stereo flag and then were setting the VIC field in the AVI infoframe to 0.

2013-10-01drm: Add a STEREO_3D capability to the SET_CLIENT_CAP ioctlDamien Lespiau1-0/+3
This capability allows user space to control the delivery of modes with the 3D flags set. This is to not play games with current user space users not knowing anything about stereo 3D flags and that could try to set a mode with one or several of those bits set. So, the plan is to remove the stereo modes from the list of modes we give to DRM clients by default, and let them through if we are being told otherwise. stereo_allowed is bound to the drm_file structure to make it a per-client setting, not a global one. v2: Replace clearing 3D flags by discarding the stereo modes now that they are regular modes. v3: SET_CAP -> SET_CLIENT_CAP rename (Chris Wilson) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-10-01drm: Add HDMI stereo 3D flags to struct drm_mode_modeinfoDamien Lespiau1-0/+14
HDMI 1.4a defines a few layouts that we'd like to expose.

2013-10-01drm: Add a SET_CLIENT_CAP ioctlDamien Lespiau1-0/+2
This ioctl can be used to turn some knobs in a DRM driver. The client can ask the DRM core for an alternate view of the reality: it can be useful to be able to instruct the core that the DRM client can handle new functionnality that would otherwise break current ABI. v2: Rename to ioctl from SET_CAP to SET_CLIENT_CAP (Chris Wilson) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
