2016-08-30drm/imx: fix crtc vblank state regressionLucas Stach
The atomic conversion lost the notification to let the DRM core know about the current state of the CRTC vblank interrupts. This regressed the ability of the core to reject page flip attempts on currently disabled CRTCs. Add back the notifications.

2016-08-30xfs: track log done items directly in the deferred pending work itemDarrick J. Wong
Christoph reports slab corruption when a deferred refcount update aborts during _defer_finish(). The cause of this was broken log item state tracking in xfs_defer_pending -- upon an abort, _defer_trans_abort() will call abort_intent on all intent items, including the ones that have already had a done item attached. This is incorrect because each intent item has 2 refcount: the first is released when the intent item is committed to the log; and the second is released when the _done_ item is committed to the log, or by the intent creator if there is no done item. In other words, once we log the done item, responsibility for releasing the intent item's second refcount is transferred to the done item and /must not/ be performed by anything else. The dfp_committed flag should have been tracking whether or not we had a done item so that _defer_trans_abort could decide if it needs to abort the intent item, but due to a thinko this was not the case. Rip it out and track the done item directly so that we do the right thing w.r.t. intent item freeing. Signed-off-by: Darrick J.

2016-08-29gpu: ipu-v3: Add FSU channel linking supportSteve Longerbeam
Adds functions to link and unlink source channels to sink channels in the FSU: int ipu_fsu_link(struct ipu_soc *ipu, int src_ch, int sink_ch); int ipu_fsu_unlink(struct ipu_soc *ipu, int src_ch, int sink_ch); The channels numbers are usually IDMAC channels, but they can also be channels that do not transfer data to or from memory. The following convenience functions can be used in place of ipu_fsu_link/unlink() when both source and sink channels are IDMAC channels: int ipu_idmac_link(struct ipuv3_channel *src, struct ipuv3_channel *sink); int ipu_idmac_unlink(struct ipuv3_channel *src, struct ipuv3_channel *sink); So far the following links are supported: IPUV3_CHANNEL_IC_PRP_ENC_MEM -> IPUV3_CHANNEL_MEM_ROT_ENC PUV3_CHANNEL_IC_PRP_VF_MEM -> IPUV3_CHANNEL_MEM_ROT_VF IPUV3_CHANNEL_IC_PP_MEM -> IPUV3_CHANNEL_MEM_ROT_PP IPUV3_CHANNEL_CSI_DIRECT -> IPUV3_CHANNEL_CSI_VDI_PREV More links can be added to the fsu_link_info[] array.

Just for the struct drm_mode_object base class. The header file was already partially extracted to help untangle the include loops. v2: - Also move the generic get/set property ioctls. At first this seemed like a bad idea since it requires making drm_mode_crtc_set_obj_prop non-static. But eventually that will get split away too (like the connector version already is) for both crtc and planes. Hence I reconsidered. - drm_mode_object.[hc] instead of drm_modeset.[hc], which requires renaming the drm_modeset.h header I already started building up.

2016-08-29drm/fb-helper: don't call remove_conflicting_framebuffers for FB=m && DRM=yArnd Bergmann
When CONFIG_DRM_KMS_FB_HELPER is disabled, we can have a configuration in which some DRM drivers are built-in, but the framebuffer core is a loadable module. This results in a link error, such as: drivers/gpu/drm/radeon/radeon.o: In function `radeon_pci_probe': radeon_kfd.c:(.text.radeon_pci_probe+0xbc): undefined reference to `remove_conflicting_framebuffers' drivers/gpu/drm/amd/amdgpu/amdgpu.o: In function `amdgpu_pci_probe': amdgpu_mn.c:(.text.amdgpu_pci_probe+0xa8): undefined reference to `remove_conflicting_framebuffers' drivers/gpu/drm/mgag200/mgag200.o: In function `mga_vram_init': mgag200_ttm.c:(.text.mga_vram_init+0xa8): undefined reference to `remove_conflicting_framebuffers' drivers/gpu/drm/mgag200/mgag200.o: In function `mga_pci_probe': mgag200_ttm.c:(.text.mga_pci_probe+0x88): undefined reference to `remove_conflicting_framebuffers' Makefile:969: recipe for target 'vmlinux' failed This changes the compile-time check to IS_REACHABLE, which means we end up not calling remove_conflicting_framebuffers() in the configuration, which seems good enough, as we know that no framebuffer driver is loaded by the time that the built-in DRM driver calls remove_conflicting_framebuffers. We could alternatively avoid the link error by forcing CONFIG_FB to not be a module in this case, but that wouldn't change anything at runtime, and just make the already convoluted set of dependencies worse here. I could not find out what happens if the fbdev driver gets loaded as a module after the DRM driver is already initialized, but that is a case that can happen with or without this patch.

2016-08-29drm/imx: add exclusive fence to plane stateLucas Stach
This allows the atomic helper to wait on them, instead of open-coding the same in the imx-drm driver. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-08-29drm/imx: fold ipu_plane_disable into ipu_disable_planeLucas Stach
ipu_disable_plane is the only left caller of ipu_plane_disable. Having those 2 similar named functions is confusing and superfluous, so fold them into 1. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-08-29drm/imx: don't destroy mode objects manually on driver unbindLucas Stach
Instead let drm_mode_config_cleanup() do the work when taking down the master device. This requires all cleanup functions to be properly hooked up to the mode object .destroy callback. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-08-29drm/imx: drop deprecated load/unload drm_driver opsLucas Stach
Drop the load/unload driver ops, as they are deprecated because of their inherent races, with devices being visible to userspace before they are fully initialized. Move this code into the driver bind/unbind routines bracketed by the proper drm_dev_alloc/register and drm_dev_unregister/unref calls.

2016-08-29drm/imx: don't call disable_plane in plane destroy pathLucas Stach
When the destroy path is called the plane should already be disabled. If not, this is a core bug and should not be worked around in the driver. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-08-29drm/imx: Add active plane reconfiguration supportLiu Ying
We don't support configuring active plane on-the-fly for imx-drm. The relevant CRTC should be disabled before the plane configuration. Of course, the plane itself should be disabled as well. This patch adds active plane reconfiguration support by forcing CRTC mode change in plane's ->atomic_check callback so that the CRTC will be disabled before the plane configuration.
