2017-03-27drm/i915: kill intel_ddi_pll_select()Paulo Zanoni3-26/+11
All it does is pick the encoder and call intel_get_shared_dpll(). We can just do this in the caller. One less indirection level during code reading. As another plus, now the two callers of intel_get_shared_dpll() are {ironlake,haswell}_crtc_compute_clock().

2017-03-27drm/tegra: Don't use modeset_lock_crtcDaniel Vetter1-4/+4
Yes the help text is unhelpful, but atomic drivers should never use this. Just grab the lock without context or anything. Also an aside: Checking ->active like this doesn't protect against nonblocking commits, this is rather bogus.

2017-03-27drm/i915/execlists: Wrap tail pointer after reset tweakingChris Wilson2-3/+11
If the request->wa_tail is 0 (because it landed exactly on the end of the ringbuffer), when we reconstruct request->tail following a reset we fill in an illegal value (-8 or 0x001ffff8). As a result, RING_HEAD is never able to catch up with RING_TAIL and the GPU spins endlessly. If the ring contains a couple of breadcrumbs, even our hangcheck is unable to catch the busy-looping as the ACTHD and seqno continually advance. v2: Move the wrap into a common intel_ring_wrap().

I noticed that gcc was spilling the CSB to the stack, so rearrange the code to be more compact. Spilling in this function is slightly more interesting due to the mmio reads acting as memory barriers and so end up flushing the stack spills.

2017-03-27drm/i915: Restore marking context objects as dirty on pinningChris Wilson1-0/+2
Commit e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc") converted the legacy intel_ringbuffer submission to the same context pinning mechanism as execlists - that is to pin the context until the subsequent request is retired. Previously it used the vma retirement of the context object to keep itself pinned until the next request (after i915_vma_move_to_active()). In the conversion, I missed that the vma retirement was also responsible for marking the object as dirty. Mark the context object as dirty when pinning (equivalent to execlists) which ensures that if the context is swapped out due to mempressure or suspend/hibernation, when it is loaded back in it does so with the previous state (and not all zero).

2017-03-27drm: bochs: Prevent double-free of fb helperGabriel Krisman Bertazi1-1/+3
If fbdev registration fails for whatever reason, the error path of bochs_fbdev_init() will call bochs_fbdev_fini(), but since an fbdev initialization error is not fatal to the probe function, a subsequent device removal will try to call bochs_fbdev_fini() again, hitting the Oops below. This was detected by 0-day with a failing framebuffer registration and CONFIG_DEBUG_TEST_DRIVER_REMOVE=y. This reproduces the scenario I mentioned above at insmod time, because the test attempts to remove the device right after probing. root@debian:~# insmod bochs-drm.ko [ 17.609635] [drm] Found bochs VGA, ID 0xb0c0.

2017-03-27drm/atomic: Introduce drm_atomic_helper_shutdownDaniel Vetter6-25/+57
The trouble here is that it does multiple atomic commits under one drm_modeset_lock_all, which breaks the behind-the-scenes acquire context magic that function pulls off. It's much better to have one overall atomic commit. That we still have multiple atomic commits prevents us from adding some pretty useful debug checks to the atomic machinery. Hence it is really a bad idea to call the legacy drm_crtc_force_disable_all() function. There's 2 atomic drivers using this still, nouveau and tinydrm. To fix this, introduce a new drm_atomic_helper_shutdown() by extracting the code from i915. While at it improve kernel-doc and catch future offenders by sprinkling a WARN_ON into the legacy function. We should probably move those into the legacy modeset helpers, too ... v2: Make it compile on arm drivers too (Noralf). v3: Correct kerneldoc to point at _disable_all().

2017-03-27drm: dw_hdmi: Don't rely on the status of the bridge for updating HPDRomain Perier1-1/+1
Currently, the irq handler that monitors changes for HPD and RX_SENSE relies on the status of the bridge for updating the status of the HPD. The update is done only when the bridge is enabled. However, on Rockchip platforms we have found use cases where it could be a problem. When HDMI is being used, turning off/on the screen or unplugging/re-plugging the cable, the following simplified code path will happen: - dw_hdmi_irq() will be triggered by an HPD event, as the bridge is on hdmi->disabled is false, then the handler will update the rxsense flag accordingly. - dw_hdmi_update_power() will be invoked with the mode DRM_FORCE_UNSPECIFIED and rxsense == 1, so dw_hdmi_poweroff() will be called and the PHY will be desactivated (its pixel clocks and TMDS) [...] - dw_hdmi_bridge_disable() will be invoked, the bridge will be marked as disabled. - dw_hdmi_irq() will be triggered by an HPD event, as the bridge is currently disabled the HPD status won't be updated, so hdmi->rxsense won't be changed. Even if the data part of the PHY is disabled, this information coming from the HDMI Transmitter is correct and should be saved. [...] - dw_hdmi_bridge_enable() will be invoked, the bridge will be marked as enabled. - dw_hdmi_update_power() will be called. When hdmi->force is equal to DRM_FORCE_UNSPECIFIED the function will rely on hdmi->rxsense. If this field has not been updated by the irq handler, it will be false and DRM_FORCE_ON won't be put to hdmi->force. Consequently, most of the time dw_hdmi_poweron() won't be called in this use case, TMDS won't be re-enabled the PHY won't be re-initialized, resulting in a "Signal not found". This commit fixes the issue by removing the check for "!hdmi->disabled". As already explained, even if the PHY is partially disabled, information coming from HDMI Transmitter about HPD should be saved for a later use.

This pull request is the first of this entire rc cycle and it has all of the suitable fixes so far and it's still only about 20 patches. The fix for the minor breakage cause by the dma mapping patchset is in here, as well as a couple other potential oops fixes, but the rest is more minor. Summary: - fix for dma_ops change in this kernel, resolving the s390, powerpc, and IOMMU operation - a few other oops fixes - the rest are all minor fixes" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: IB/qib: fix false-postive maybe-uninitialized warning RDMA/iser: Fix possible mr leak on device removal event IB/device: Convert ib-comp-wq to be CPU-bound IB/cq: Don't process more than the given budget IB/rxe: increment msn only when completing a request uapi: fix rdma/mlx5-abi.h userspace compilation errors IB/core: Restore I/O MMU, s390 and powerpc support IB/rxe: Update documentation link RDMA/ocrdma: fix a type issue in ocrdma_put_pd_num() IB/rxe: double free on error RDMA/vmw_pvrdma: Activate device on ethernet link up RDMA/vmw_pvrdma: Dont hardcode QP header page RDMA/vmw_pvrdma: Cleanup unused variables infiniband: Fix alignment of mmap cookies to support VIPT caching IB/core: Protect against self-requeue of a cq work item i40iw: Receive netdev events post INET_NOTIFIER state
2017-03-25Merge branch 'stable-4.11' of git://git.infradead.org/users/pcmoore/auditLinus Torvalds3-255/+399
Pull audit fix from Paul Moore: "We've got an audit fix, and unfortunately it is big. While I'm not excited that we need to be sending you something this large during the -rcX phase, it does fix some very real, and very tangled, problems relating to locking, backlog queues, and the audit daemon connection. This code has passed our testsuite without problem and it has held up to my ad-hoc stress tests (arguably better than the existing code), please consider pulling this as fix for the next v4.11-rcX tag" * 'stable-4.11' of git://git.infradead.org/users/pcmoore/audit: audit: fix auditd/kernel connection state tracking

2017-03-25drm/todo: Add tinydrm refactoring ideasDaniel Vetter1-0/+70
Discussed with Noralf on the list a bit. An open question is tinydrm vs. drm_panel, but until we have a clear idea what's really needed in that space, I think it's best to just move forward with what we have.
