Grab bag for all the special cases: - i9xx_check_fifo_underruns is only called from crtc_enable hooks, i.e. process context. - i915_enable_asle_pipestat is only called from interrupt postinstall hooks. So again process context. - gen8_irq_power_well_post_enable is called from the runtime pm code, which again means process context. - The open-coded hpd_irq_setup loop in _thaw is also running in process context. So for all of them the plain _irq variant is sufficient. Reviewed-by:

irq handlers always run with interrupts locally disabled, so plain spinlocks is all we need. I've also reviewed again that they all follow the _irq_handler postfix convention. Reviewed-by:

All the interrupt setup/teardown hooks are always run from plain process context. So again just the _irq variant is good enough. Reviewed-by:

Work functions are in process context, so plain _irq spinlock variants is all we need. The hpd reenable work didn't follow the _work/_work_func postfix naming scheme, so adjust that while at it. Reviewed-by:

->detect callbacks are only ever called from process context, and there's no fancy nesting going on here. So plain _irq spinlock variants is what we want. Reviewed-by:

i915_capture_error_state can be called from all kinds of contexts, so needs the full irqsave dance. But the other two places to grab and release the error state are only called from process context. So simplify them to the plaine _irq spinlock versions to clarify the locking semantics. Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com Reviewed-by:

Now we tackle the functions also called from interrupt handlers. - intel_check_page_flip is exclusively called from irq handlers, so a plain spin_lock is all we need. In i915_irq.c we have the convention to give all such functions an _irq_handler postfix, but that would look strange and als be a bit a misleading name. I've opted for a WARN_ON(!in_irq()) instead. - The other two places left are called both from interrupt handlers and from our reset work, so need the full irqsave dance. Annotate them with a short comment. Reviewed-by:

It's good practice to use the more specific versions for irq save spinlocks both as executable documentation and to enforce saner design. The _irqsave version really should only be used if the calling context is unknown and there's a good reason to call a function from all kinds of places. This is the first step whice replaces all occurances of _irqsave in process context with the simpler irq disable/enable variants. We don't have any funky spinlock nesting going on, especially since the event_lock is the outermost of the irq/vblank related spinlocks. Reviewed-by:

We changed to an interrupt based vblank wait (as opposed to polling) in: commit 44bd93a3d367913d883be6abba9a6e51a53c4e90 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 25 23:36:44 2014 +0200 drm/i915: Use generic vblank wait However we already had vblank waits on the wrong side of drm_vblank_{on,off}() calls due to various workarounds, so now we get a warning more or less every time we do a modeset, and we fail to wait for the vblank like we should. Move the drm_vblank_{on,off}() calls back out from intel_crtc_{enable,disable}_planes() so that all of these vblank waits return to proper operation. Also move the cxsr wait a bit earlier so that we can keep the encoder disable after we've turned off vblanks. Moving stuff out from the plane enable/disable functions seems preferrable to moving the workaround stuff in since the workarounds are required only on specific platforms. While at it switch over to the drm_crtc_ variants of the vblank on/off functions.

Yet another place that wasn't properly transformed when implementing SOix. While at it convert the checks to WARN_ON on gen5+ (since we don't have UMS potentially doing stupid things on those platforms). And also add the corresponding checks to the put functions (again with a WARN_ON) for gen5+. v2: Drop the WARNINGS in the irq_put functions (including the existing one for vebox), Chris convinced me that they're not that terribly useful. v3: Don't forget about execlist code.

We want to enable/disable display IRQs only if global i915 IRQs are enabled. To check the latter it's not enough to consult the DRM dev->irq_enabled flag, since runtime PM can disable/enable IRQs and it won't adjust this flag only the i915 specific dev_priv->pm._irqs_disabled flag. Fix this by using the proper intel_irqs_enabled() helper instead. Fortunately this didn't cause an actual problem since even if we enabled display IRQs too early (before enabling global i915 IRQs) the VLV_MASTER_IER would still be clear masking all IRQs.

To make the code a bit more undestandable move the intel_crtc->cursor_base assignment into the low level update cursor routines. That's were we compare the current value with the new one so immediately seeing that it gets assigned only afterwards helps one to understand that it gets assigned only after the comparison.

As a preparation for atomic updates we need to split the code to check everything we are going to commit first. This patch starts the work to split intel_primary_plane_setplane() into check() and commit() parts. More work is expected on this to get a better split of the two steps. Ideally the commit() step should never fail. Signed-off-by:

gen6 and earlier conflate address space selection (ppgtt vs ggtt) with the security bit (i.e. only privileged batches were allowed to run from ggtt). From Haswell only, you are able to select the security bit separate from the address space - and we always requested to use ppgtt. This breaks the golden render state batch execution with full-ppgtt as that is only present in the global GTT and more generally any secure batch that is not colocated in the ppgtt and ggtt. So we need to disable the use of the ppgtt selector bit for secure batches, or else we hang immediately upon boot and thence after every GPU reset... v2: Only HSW differentiates between secure dispatch and ggtt, so simply ignore the differentiation and always use secure==ggtt.

Before we process the final unbind on an object and move it to the unbound list, it is semantically cleaner if there are no more active references to the object. (An active reference would imply that it was still being accessed by the GPU after it became inaccessible.) The caveat is that all callsites must be prepared for the object to disappeared during the unbind - i.e. they must hold their own reference. Signed-off-by:
