Mika encountered one pathological scenario under X where acquiring all the mm locks (required to insert a mmu notifier) was very slow, so slow that by the time we tried to lock the struct_mutex with the usual call to i915_mutex_lock_interruptible(), X's signal timer had fired causing us to restart the ioctl (and so looped indefinitely). While I suspect this is the result of another bug (something leaking mm perhaps?) we can forgo the error checking and interuptible nature of the lock here so we only have to pay the expense once and get on with it. This does expose the userptr creation routine to a driver livelock though by not being interruptible. Signed-off-by:

When the modeset code is reached with a CRTC that only needs a flip, the code that assigns PLLs is skipped. But since there is still a state swap for that CRTC, the current PLL assignment needs to be preserved. I missed the ddi_pll_sel field in the following commit, which causes warnings in DDI platforms. commit 4978cc93 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Tue Apr 21 17:13:21 2015 +0300 drm/i915: Preserve shared DPLL information in new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90410Signed-off-by:

In the following commit, the place where the contents of dpll_hw_state in crtc_state where zeroed was changed. Prior to that commit, it happened when the new state was allocated, but now that happens just before the call the .crtc_compute_clock() hook. The DP code for SKL, however, sets up the (private) PLL in the encoder compute config function that has already run by the time that memset() is reached, causing the previous value to be lost. This patch fixes the issue by moving the memset() down the call chain, so that it is only called if the values in dpll_hw_state are going to be updated. commit 4978cc93 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Tue Apr 21 17:13:21 2015 +0300 drm/i915: Preserve shared DPLL information in new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90462Signed-off-by:

Add one explicit discard of __iomem address space qualifier in validate_vbt(), and respect it otherwise. This adds clarity in the code, and reduces the sparse warnings from the module to just one. Quoting Daniel, "The vbt really is plain old memory. Except that it's reserved in the e820 table as something special and hence treated as io range by the kernel. But it is memory, hence casting away the __iomem is imo the right approach." Signed-off-by:

Use HOTPLUG_INT_STATUS_G4X instead of HOTPLUG_INT_STATUS_I915 on VLV/CHV so that we don't confuse the AUX status bits with SDVO status bits. Avoid pointless log spam as below while handling AUX interrupts: [drm:intel_hpd_irq_handler] hotplug event received, stat 0x00000040, dig 0x00000000 [drm:intel_hpd_irq_handler] hotplug event received, stat 0x00000040, dig 0x00000000 [drm:intel_hpd_irq_handler] hotplug event received, stat 0x00000040, dig 0x00000000 [drm:intel_hpd_irq_handler] hotplug event received, stat 0x00000040, dig 0x00000000 [drm:intel_hpd_irq_handler] hotplug event received, stat 0x00000040, dig 0x00000000 [drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x71450064 Note that there's no functional issue, it's just that the sdvo bits overlap with the dp aux bits. Hence every time we receive an aux interrupt we also think there's an sdvo hpd interrupt, but due to lack of any sdvo encoders nothing ever happens because of that. Signed-off-by:

As we perform the mmio-flip without any locking and then try to acquire the struct_mutex prior to dereferencing the request, it is possible for userspace to queue a new pageflip before the worker can finish clearing the old state - and then it will clear the new flip request. The result is that the new flip could be completed before the GPU has finished rendering. The bugs stems from removing the seqno checking in commit 536f5b5e Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Thu Nov 6 11:03:40 2014 +0200 drm/i915: Make mmio flip wait for seqno in the work function Signed-off-by:

Synchronising to an object active on the same ring is a no-op, for the benefit of execbuffer scheduler. However, for CS flips this means that we can forgo checking whether the last write request of the object is actually queued and more importantly whether the cache flush for the write was emitted.

We no longer interpolate domains in the same manner, and even if we did, we should trust setting either of the other write domains would trigger an invalidation rather than force it.
