BSpec says: "Overlay Clock Gating Must be Disabled: Overlay & L2 Cache clock gating must be disabled in order to prevent device hangs when turning off overlay.SW must turn off Ovrunit clock gating (6200h) and L2 Cache clock gating (C8h)." We only turned off the overlay clock gating (due to lack of docs I presume). After a bit of experimentation it looks like the the magic C8h register lives in the PCI config space of device 0, and the magic bit appears to be bit 2. Or at the very least this eliminates the GPU death after MI_OVERLAY_OFF. L2 clock gating seems to save ~80mW, so let's keep it on unless we need to actually use the overlay. Also let's move the OVRUNIT clock gating to the same place since we can, and 845 supposedly doesn't need it. Signed-off-by:

Do the overlay frontbuffer tracking properly so that it matches the state of the overlay on/off/continue requests. One slight problem is that intel_frontbuffer_flip_complete() may get delayed by an arbitrarily liong time due to the fact that the overlay code likes to bail out when a signal occurs. So the flip may not get completed until the ioctl is restarted. But fixing that would require bigger surgery, so I decided to ignore it for now. Signed-off-by:

Apparently some VLV BIOSen like to leave the VDD force bit enabled even for power seqeuncers that aren't properly hooked up to any port. That will result in a imbalance in the AUX power domain refcount when we stat to use said power sequencer as edp_panel_vdd_on() will not grab the power domain reference if it sees that the VDD is already on. To fix this let's make sure we turn off the VDD force bit when we initialize the power sequencer registers. That is, unless it's being done from the init path since there we are actually initializing the registers for the current power sequencer and we don't want to turn VDD off needlessly as that would require waiting for the power cycle delay before we turn it back on.

Don't even tell the mm allocator to handle the first page of stolen on the affected platforms. This means that we won't inherit the FB in case the BIOS decides to put it at the start of stolen. But the BIOS should not be putting it at the start of stolen since it's going to get corrupted. I suppose the bug here is that some pixels at the very top of the screen will be corrupted, so it's not exactly easy to notice. We have confirmation that the first page of stolen does actually get corrupted, so I really think we should do this in order to avoid any possible future headaches, even if that means losing BIOS framebuffer inheritance. Let's not use the HW in a way it's not supposed to be used. Notice that now ggtt->stolen_usable_size won't reflect the ending address of the stolen usable range anymore, so we have to fix the places that rely on this. To simplify, we'll just use U64_MAX. v2: don't even put the first page on the mm (Chris) v3: drm_mm_init() takes size instead of end as argument (Ville) v4: add a comment explaining the reserved ranges (Chris) use 0 for start and U64_MAX for end when possible (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94605 Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

VLV apparently gets upset if the PPS for a pipe currently driving an external DP port gets used for VDD stuff on another eDP port. The DP port falls over and fails to retrain when this happens, leaving the user staring at a black screen. Let's fix it by also tracking which pipe is driving which DP/eDP port. We'll track this under intel_dp so that we'll share the protection of the pps_mutex alongside the pps_pipe tracking, since the two things are intimately related. I had plans to reduce the protection of pps_mutex to cover only eDP ports, but with this we can't do that. Well, for for VLV/CHV at least. For other platforms it should still be possible, which would allow AUX communication to occur in parallel for multiple DP ports. v2: Drop stray crap from a comment (Imre) Grab pps_mutex when clearing active_pipe Fix a typo in the commit message v3: Make vlv_active_pipe() static Cc: stable@vger.kernel.org Signed-off-by:

Chris Wilson authored
The requests conversion introduced a nasty bug where we could generate a new request in the middle of constructing a request if we needed to idle the system in order to evict space for a context. The request to idle would be executed (and waited upon) before the current one, creating a minor havoc in the seqno accounting, as we will consider the current request to already be completed (prior to deferred seqno assignment) but ring->last_retired_head would have been updated and still could allow us to overwrite the current request before execution. We also employed two different mechanisms to track the active context until it was switched out. The legacy method allowed for waiting upon an active context (it could forcibly evict any vma, including context's), but the execlists method took a step backwards by pinning the vma for the entire active lifespan of the context (the only way to evict was to idle the entire GPU, not individual contexts). However, to circumvent the tricky issue of locking (i.e. we cannot take struct_mutex at the time of i915_gem_request_submit(), where we would want to move the previous context onto the active tracker and unpin it), we take the execlists approach and keep the contexts pinned until retirement. The benefit of the execlists approach, more important for execlists than legacy, was the reduction in work in pinning the context for each request - as the context was kept pinned until idle, it could short circuit the pinning for all active contexts. We introduce new engine vfuncs to pin and unpin the context respectively. The context is pinned at the start of the request, and only unpinned when the following request is retired (this ensures that the context is idle and coherent in main memory before we unpin it). We move the engine->last_context tracking into the retirement itself (rather than during request submission) in order to allow the submission to be reordered or unwound without undue difficultly. And finally an ulterior motive for unifying context handling was to prepare for mock requests. v2: Rename to last_retired_context, split out legacy_context tracking for MI_SET_CONTEXT. Signed-off-by:

In a number places we hand-roll the overflow sanity check for ranges, so roll that into single macro, conceived by Chris, along with its typed variant. Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Suggested-by:

If we move the sanity checking from gen8_alloc_va_range_3lvl and gen6_alloc_va_range into i915_vma_bind, we will increase our coverage to now both callbacks. We also convert each WARN_ON over to a GEM_WARN_ON. Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Suggested-by:

In a similar spirit to GEM_BUG_ON we now also have GEM_WARN_ON, with the simple goal of expressing warnings which are truly insane, and so are only really useful for CI where we have some abusive tests. v2: - use BUILD_BUG_ON_INVALID for !DEBUG_GEM - clarify commit message Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Suggested-by:

Commit 3b3f1650 ("drm/i915: Allocate intel_engine_cs structure only for the enabled engines") introduced the dynanically allocated engine instances and created an potential use after free scenario in logical_render_ring_init where lrc_destroy_wa_ctx_obj could be called after the engine instance has been freed. This can only happen during engine setup/init error handling which luckily does not happen ever in practice. Fix is to not call lrc_destroy_wa_ctx_obj since it would have already been executed from the preceding engine cleanup. Signed-off-by:
