The merged seqno->request conversion from John called request variables req, but some (not all) of Chris' recent patches changed those to just rq. We've had a lenghty (and inconclusive) discussion on irc which is the more meaningful name with maybe at most a slight bias towards req. Given that the "don't change names without good reason to avoid conflicts" rule applies, so lets go back to a req everywhere for consistency. I'll sed any patches for which this will cause conflicts before applying. Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: John Harrison <John.C.Harrison@Intel.com> [danvet: s/origina/merged/ as pointed out by Chris - the first mass-conversion patch was from Chris, the merged one from John.] Signed-off-by:Daniel Vetter <daniel.vetter@intel.com>

Our driver compiles clean (nowadays thanks to 0day) but for me, at least, it would be beneficial if the compiler threw an error rather than a warning when it found a piece of suspect code. (I use this to compile-check patch series and want to break on the first compiler error in order to fix the patch.) v2: Kick off a new "Debugging" submenu for i915.ko Signed-off-by:

ARGB8888 is used for cursors on all platforms so we need to allow it everywhere. ABGR8888 is currently only honoured: - on VLV/CHV in sprite planes - on SKL+ for primary and sprite planes so only allow it for those platforms. Note that we only support ARGB8888/ABGR8888 on the primary plane for SKL/BXT because we have in line of sight the pipe bottom color on those platforms and because the primary plane programming on VLV/CHV doesn't anything different for those formats today. v2: Fix the logic to forbid the creation ABGR2101010 fbs (Ville) v3: Still allow the creation of ARGB8888 fbs now that cursor planes use real fb objects (found by PRTS).

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:
