Use the LLC/eLLC hotspot avoidance mode for CCS on LLC machines. This is reported to give better performance. Testing has indicated that we don't need to enforce any massive 2 or 4 MiB alignment for all compressed resources even though there are still plenty of stale comments in the spec suggesting that we do. We do need to make sure every hardware unit that deals with the compressed data uses the same hash mode.

The engine also provides a mirror of the CSB write pointer in the HWSP, but not of our read pointer. To take advantage of this we need to remember where we read up to on the last interrupt and continue off from there. This poses a problem following a reset, as we don't know where the hw will start writing from, and due to the use of power contexts we cannot perform that query during the reset itself. So we continue the current modus operandi of delaying the first read of the context-status read/write pointers until after the first interrupt. With this we should now have eliminated all uncached mmio reads in handling the context-status interrupt, though we still have the uncached mmio writes for submitting new work, and many uncached mmio reads in the global interrupt handler itself. Still a step in the right direction towards reducing our resubmit latency, although it appears lost in the noise! v2: Cannonlake moved the CSB write index v3: Include the sw/hwsp state in debugfs/i915_engine_info v4: Also revert to using CSB mmio for GVT-g v5: Prevent the compiler reloading tail (Mika) Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Michel Thierry <michel.thierry@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Zhenyu Wang <zhenyuw@linux.intel.com> Cc: Zhi Wang <zhi.a.wang@intel.com> Acked-by: NMichel Thierry <michel.thierry@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170913085605.18299-6-chris@chris-wilson.co.ukReviewed-by: NMika Kuoppala <mika.kuoppala@intel.com>

The engine provides a mirror of the CSB in the HWSP. If we use the cacheable reads from the HWSP, we can shave off a few mmio reads per context-switch interrupt (which are quite frequent!). Just removing a couple of mmio is not enough to actually reduce any latency, but a small reduction in overall cpu usage. Much appreciation for Ben dropping the bombshell that the CSB was in the HWSP and for Michel in digging out the details. v2: Don't be lazy, add the defines for the indices. v3: Include the HWSP in debugfs/i915_engine_info v4: Check for GVT-g, it currently depends on intercepting CSB mmio v5: Fixup GVT-g mmio path v6: Disable HWSP if VT-d is active as the iommu adds unpredictable memory latency. (Mika) v7: Also markup the CSB read with READ_ONCE() as it may still be an mmio read and we want to stop the compiler from issuing a later (v.slow) reload.

At the time of commit 1f767e02 ("drm/i915: HWS must be in the mappable region for g33"), drm_mm insertion would often default to placing a new object high in the zone forcing us to specify that certain HWSP must be bound within the low mappable region. Since then, drm_mm has gained more finesse over its placement and exposes that to the caller, commit 4e64e553 ("drm: Improve drm_mm search (and fix topdown allocation) with rbtrees"). As such where possible we want the HWSP to be outside of the mappable aperture and so need to specify that can be pinned high.

由 Daniele Ceraolo Spurio 提交于
On gen8+ we're currently using the PPHWSP of the kernel ctx as the global HWSP. However, when the kernel ctx gets submitted (e.g. from __intel_autoenable_gt_powersave) the HW will use that page as both HWSP and PPHWSP. This causes a conflict in the register arena of the HWSP, i.e. dword indices below 0x30. We don't current utilize this arena, but in the following patches we will take advantage of the cached register state for handling execlist's context status interrupt. To avoid the conflict, instead of re-using the PPHWSP of the kernel ctx we can allocate a separate page for the HWSP like what happens for pre-execlists platform. v2: Add a use-case for the register arena of the HWSP.

Using the HWSP ggtt_offset to get the lrca offset is only correct if the HWSP happens to be before it (when we reuse the PPHWSP of the kernel context as the engine HWSP). Instead of making this assumption, get the lrca offset from the kernel_context engine state. And while looking at this part of the GuC interaction, it was also noticed that the firmware expects the size of only the engine context (context minus the execlist part, i.e. don't include the first 80 dwords), so pass the right size. v2: Use the new macros to prevent abusive overuse of the old ones (Chris).

Not only the context image consist of two parts (the PPHWSP, and the logical context state), but we also allocate a header at the start of for sharing data with GuC. Thus every lrc looks like this: | [guc] | [hwsp] [logical state] | |<- our header ->|<- context image ->| So far, we have oversimplified whenever we use each of these parts of the context, just because the GuC header happens to be in page 0, and the (PP)HWSP is in page 1. But this had led to using the same define for more than one meaning (as a page index in the lrc and as 1 page). This patch adds defines for the GuC shared page, the PPHWSP page and the start of the logical state. It also updated the places where the old define was being used. Since we are not changing the size (or format) of the context, there are no functional changes. v2: Use PPHWSP index for hws again.

Disable device ready before shutdown command was added previously to avoid a split screen issue seen on dual link DSI panels. As of now, dual link is not supported and will need some rework in the upstream code. For single link DSI panels, the change is not required.

During IGT testing it has been shown that the specification defined polling time of 1 us for FCLK_DONE, is sometimes not enough. The issue is still reproducible while disabling C-states through the PM QoS framework and also while disabling preemtion. From this the most plausible explanation is that the issue is due to a firmware flaw. As a workaround, it is better to wait a little bit longer for the FCLK_DONE to come around, than to leave with an DRM_ERROR and having FCLK_DONE at a randome time after. While spinning a list of igt tests prone to reproduce the issue the FCLK_DONE poll failed at approximately 2% of the invocations of the bdw_set_cdclk function. The longest poll time during this testing was measured to ~7us. So, the suggested new poll time of 100us is on the safe side. v2: Added more documentation about investigations done.

No functional change is expected here since at this point PSR is not allowed to go to any active state. In other words, not really enabled. However let's do in a separated patch so it gets clear on what is change and specially it can helps on bisect case if we figure something has caused changes in behaviour. But this needs to be done before we make the vfunc to enable source to be in parity with VLV implementation.

This sequence is part of enable source anyways, but they only need to be executed once and not on every activation, So let's re-create hsw_enable_source. v2: Avoid changing order here to avoid changing behaviour as suggested by Jani. v3: Rebased on top of commit d2419ffc ("drm/i915: Plumb crtc_state to PSR enable/disable") Cc: Jani Nikula <jani.nikula@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Vathsala Nagaraju <vathsala.nagaraju@intel.com> Signed-off-by: NRodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: NDhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170907230041.22978-7-rodrigo.vivi@intel.com

VSC package is decided per eDP spec for psr1 or psr2, and not per platform, so let's unify it and kill "skl" func. v2: Rebased on top of commit d2419ffc ("drm/i915: Plumb crtc_state to PSR enable/disable") Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Vathsala Nagaraju <vathsala.nagaraju@intel.com> Signed-off-by: NRodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: NDhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170907230041.22978-6-rodrigo.vivi@intel.com

On HSW+ the real activate of PSR is decided by the source after certain amount of configured idle frames. However for the driver perspective where we track psr.active variable this function here is the actual activate one. So let's rename it before moving to vfunc with that. v2: Fix typo on commit message (DK).

VLV/CHV has a total different PSR implementation than the other platforms, so let's start moving that to vfuncs.

We really don't want to setup vfuncs and lock mutexes on platforms that has no support to PSR. Also we know what platforms they are so let's do it quietly.

We should go through the error handling path to decrease the 'framebuffer_references' as done everywhere else in this function.

If we know that we will completely fill a pagetable (i.e. we are inserting a complete set of 512 pages), we can skip prefilling that PT with scratch entries. If we have to abort the insertion prior to writing the real entries, we will teardown the pagetable and remove it from the page directory (so that we will restart the allocation next time). We could do similar tricks for the PD and PDP, but the likelihood of a single insertion covering the entire 512 entries diminishes, as do the cycle savings. The saving are even greater (relatively) when we are preallocating page tables for huge pages, as then we never need to fill the page table.
