Cannonlake is a Intel® Processor containing Intel® HD Graphics following Kabylake. It is Gen10. Let's start by adding the platform definition based on previous platforms but yet as alpha_support. On following patches we will start adding PCI IDs and the platform specific changes. CNL has an increased DDB size as Damien had previously noticed and provided a separated patch that got squashed here. v2: Squash DDB size here per Ander request.

The first two bytes of PCI ID for CNP_LP PCH are the same as that of SPT_LP. We should really be looking at the first 9 bits instead of the first 8 to identify platforms, although this seems to have not caused any problems on earlier platforms.

BXT has a H/W issue with IOMMU which can lead to system hangs when Aperture accesses are queued within the GAM behind GTT Accesses. This patch avoids the condition by wrapping all GTT updates in stop_machine and using a flushing read prior to restarting the machine. The stop_machine guarantees no new Aperture accesses can begin while the PTE writes are being emmitted. The flushing read ensures that any following Aperture accesses cannot begin until the PTE writes have been cleared out of the GAM's fifo. Only FOLLOWING Aperture accesses need to be separated from in flight PTE updates. PTE Writes may follow tightly behind already in flight Aperture accesses, so no flushing read is required at the start of a PTE update sequence. This issue was reproduced by running igt/gem_readwrite and igt/gem_render_copy simultaneously from different processes, each in a tight loop, with INTEL_IOMMU enabled. This patch was originally published as: drm/i915: Serialize GTT Updates on BXT v2: Move bxt/iommu detection into static function Remove #ifdef CONFIG_INTEL_IOMMU protection Make function names more reflective of purpose Move flushing read into static function v3: Tidy up for checkpatch.pl Testcase: igt/gem_concurrent_blit Signed-off-by: NJon Bloomfield <jon.bloomfield@intel.com> Cc: John Harrison <john.C.Harrison@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1495641251-30022-1-git-send-email-jon.bloomfield@intel.comReviewed-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk>

The i915_priolist are allocated within an atomic context on a path where we wish to minimise latency. If we use a dedicated kmem_cache, we have the advantage of a local freelist from which to service new requests that should keep the latency impact of an allocation small. Though currently we expect the majority of requests to be at default priority (and so hit the preallocate priolist), once userspace starts using priorities they are likely to use many fine grained policies improving the utilisation of a private slab.

This change is pre-emptively aiming to avoid a potential cause of kernel logging noise in case some condition were to result in us seeing invalid OA reports. The workaround for the OA unit's tail pointer race condition is what avoids the primary known cause of invalid reports being seen and with that in place we aren't expecting to see this notice but it can't be entirely ruled out. Just in case some condition does lead to the notice then it's likely that it will be triggered repeatedly while attempting to append a sequence of reports and depending on the configured OA sampling frequency that might be a large number of repeat notices. v2: (Chris) avoid inconsistent warning on throttle with printk_ratelimit() v3: (Matt) init and summarise with stream init/close not driver init/fini Signed-off-by: NRobert Bragg <robert@sixbynine.org> Reviewed-by: NMatthew Auld <matthew.auld@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170511154345.962-9-lionel.g.landwerlin@intel.comSigned-off-by: NChris Wilson <chris@chris-wilson.co.uk>

There's a HW race condition between OA unit tail pointer register updates and writes to memory whereby the tail pointer can sometimes get ahead of what's been written out to the OA buffer so far (in terms of what's visible to the CPU). Although this can be observed explicitly while copying reports to userspace by checking for a zeroed report-id field in tail reports, we want to account for this earlier, as part of the _oa_buffer_check to avoid lots of redundant read() attempts. Previously the driver used to define an effective tail pointer that lagged the real pointer by a 'tail margin' measured in bytes derived from OA_TAIL_MARGIN_NSEC and the configured sampling frequency. Unfortunately this was flawed considering that the OA unit may also automatically generate non-periodic reports (such as on context switch) or the OA unit may be enabled without any periodic sampling. This improves how we define a tail pointer for reading that lags the real tail pointer by at least %OA_TAIL_MARGIN_NSEC nanoseconds, which gives enough time for the corresponding reports to become visible to the CPU. The driver now maintains two tail pointers: 1) An 'aging' tail with an associated timestamp that is tracked until we can trust the corresponding data is visible to the CPU; at which point it is considered 'aged'. 2) An 'aged' tail that can be used for read()ing. The two separate pointers let us decouple read()s from tail pointer aging. The tail pointers are checked and updated at a limited rate within a hrtimer callback (the same callback that is used for delivering POLLIN events) and since we're now measuring the wall clock time elapsed since a given tail pointer was read the mechanism no longer cares about the OA unit's periodic sampling frequency. The natural place to handle the tail pointer updates was in gen7_oa_buffer_is_empty() which is called as part of blocking reads and the hrtimer callback used for polling, and so this was renamed to oa_buffer_check() considering the added side effect while checking whether the buffer contains data.

Implement proper two stage watermark programming for g4x. As with other pre-SKL platforms, the watermark registers aren't double buffered on g4x. Hence we must sequence the watermark update carefully around plane updates. The code is quite heavily modelled on the VLV/CHV code, with some fairly significant differences due to the different hardware architecture: * g4x doesn't use inverted watermark values * CxSR actually affects the watermarks since it controls memory self refresh in addition to the max FIFO mode * A further HPLL SR mode is possible with higher memory wakeup latency * g4x has FBC2 and so it also has FBC watermarks * max FIFO mode for primary plane only (cursor is allowed, sprite is not) * g4x has no manual FIFO repartitioning * some TLB miss related workarounds are needed for the watermarks Actually the hardware is quite similar to ILK+ in many ways. The most visible differences are in the actual watermakr register layout. ILK revamped that part quite heavily whereas g4x is still using the layout inherited from earlier platforms. Note that we didn't previously enable the HPLL SR on g4x. So in order to not introduce too many functional changes in this patch I've not actually enabled it here either, even though the code is now fully ready for it. We'll enable it separately later on.

When discussing a new WC mmap, we based the interface upon the assumption that GTT was fully coherent. How naive! Commits 3b5724d7 ("drm/i915: Wait for writes through the GTT to land before reading back") and ed4596ea ("drm/i915/guc: WA to address the Ringbuffer coherency issue") demonstrate that writes through the GTT are indeed delayed and may be overtaken by direct WC access. To be safe, if userspace is mixing WC mmaps with other potential GTT access (pwrite, GTT mmaps) it should use set_domain(WC).

These params are passed by value, const qualifiers are ignored any way. While around, unify timeout_ms type from long to int.

In some cases we may want to spend more time in atomic wait than hardcoded 2us. Let's add additional fast timeout parameter to allow flexible configuration of atomic timeout before switching into heavy wait. Add also possibility to return registry value to avoid extra read. v2: use explicit fast timeout (Tvrtko/Chris) allow returning register value (Chris) Signed-off-by: NMichal Wajdeczko <michal.wajdeczko@intel.com> Suggested-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/20170407160145.181328-1-michal.wajdeczko@intel.comReviewed-by: NChris Wilson <chris@chris-wilson.co.uk> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk>

There is no need to specify timeout as unsigned long since this parameter will be consumed by usecs_to_jiffies() which expects unsigned int only.

By using the same structure for both interruptible and uninterruptible locking in shrinker code, combined with the information that mm.interruptible is only being written to, the code can be greatly simplified. Also removing the i915_gem_ prefix from the locking functions so that nobody in their wildest dreams considers exporting them.

Old devices have quite severe restrictions for using fences, and unlike more recent device (anything from Pineview onwards) we need to enforce those restrictions even for unfenced tiled access from the render pipeline.

We can't sometimes use these macros in other headers due to include and definition order. As i915_utils.h already contains other helper macros move these macros there. v2: checkpatch cleanup for WARN() macro.
