Rather than compute the vco inside bxt_set_cdclk() let's precompute it outside and pass it in. A small step towards a fully precomputed cdclk state.

Let's try to shrink intel_display.c a bit by moving the cdclk/rawclk stuff to a new file. It's all reasonably self contained so we don't even have to add that many non-static symbols. We'll also take the opportunity to shuffle around the functions a bit to get things in a more consistent order based on the platform. v2: Add kernel-docs (Ander) v3: Deal with IS_GEN9_BC() v4: Deal with i945gm_get_cdclk() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ander Conselvan de Oliveira <conselvan2@gmail.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170207183305.19656-1-ville.syrjala@linux.intel.com

Let's clean up the mess we have in the if ladder that assigns the .get_cdclk() hooks. The grouping of the platforms by the function results in a thing that's not really legible, so let's do it the other way around and order the if ladder by platform and duplicate whatever assignments we need. To further avoid confusion with the function names let's rename them to just fixed_<freq>_get_cdclk(). The other option would be to duplicate the functions entirely but it seems quite pointless to do that since each one just returns a fixed value. v2: Deal with i945gm_get_cdclk() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ander Conselvan de Oliveira <conselvan2@gmail.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170207183226.19537-1-ville.syrjala@linux.intel.com

Currently to establish whether GuC firmware has been loaded or submission enabled (default DRM log level), one has to detect the absence of the message saying that the load has been skipped and infer the opposite.

We're using non-canonical addresses in drm_mm, and we're making sure that userspace is using canonical addressing - both in case of softpin (verifying incoming offset) and when relocating (converting to canonical when updating offset returned to userspace). Unfortunately when considering the need for relocations, we're comparing offset from userspace (in canonical form) with drm_mm node (in non-canonical form), and as a result, we end up always relocating if our offsets are in the "problematic" range. Let's always convert the offsets to avoid the performance impact of relocations.

Following a reset, the context and page directory registers are lost. However, the queue of requests that we resubmit after the reset may depend upon them - the registers are restored from a context image, but that restore may be inhibited and may simply be absent from the request if it was in the middle of a sequence using the same context. If we prime the CCID/PD registers with the first request in the queue (even for the hung request), we prevent invalid memory access for the following requests (and continually hung engines). v2: Magic BIT(8), reserved for future use but still appears unused. v3: Some commentary on handling innocent vs guilty requests v4: Add a wait for PD_BASE fetch.

The goal of the WARN was to catch when we are still actively using the fence as we go into the runtime suspend. However, the reg->pin_count is too coarse as it does not distinguish between exclusive ownership of the fence register from activity.

In commit 86aa7e76 ("drm/i915: Assert that the context-switch completion matches our context") I added a read to the irq tasklet handler that compared the on-chip status with that of our sw tracking, using an unguarded read of the request pointer to get the context and beyond. Whilst we hold a reference to the request, we do not hold anything on the context and if we are unlucky it may be reaped from a second thread retiring the request (since it may retire the request as soon as the breadcrumb is complete, even before we finish processing the context switch) as we try to read from the context pointer. Avoid the racy read from underneath the request by storing the expected result in the execlist_port[]. v2: Include commentary about port[].request being unprotected.

It is required that the caller declare the exact number of dwords they wish to write into the ring. This is required for two reasons, we need to allocate sufficient space for the entire command packet and we need to be sure that the contents are completely written to avoid executing stale data. The current interface requires for any bug to be caught in review, the reader has to carefully count the number of intel_ring_emit() between intel_ring_begin() and intel_ring_advance(). If we record the end of the packet of each intel_ring_begin() we can also have CI check for us.

To be consistent with the recent change to enable hotplug detection early on GEN9 platforms do the same on all non-GMCH platforms starting from GEN5. On GMCH platforms enabling detection without interrupts isn't trivial, since AUX and HPD have a shared interrupt line. It could be done there too by using a SW interrupt mask, but I punt on that for now.

For LSPCON resume time initialization we need to sample the corresponding pin's HPD level, but this is only available when HPD detection is enabled. Currently we enable detection only when enabling HPD interrupts which is too late, so bring the enabling of detection earlier. This is needed by the next patch.

The drm_mm range manager (within i915_address_space) uses a special drm_mm_node that excludes the unavailable range (beyond the end of the drm_mm). However, we play games with the global GTT to use the head_node to exclude the tail page but tell ourselves that the whole range is available. This causes an issue when we try to evict using the full range of the global GTT which is wider than the drm_mm, resulting in complete confusion and catastrophe. One way to resolve this would be to use a reserved node to exclude the guard page, or we can treat the drm_mm's head_node as our guard page and assign it the appropriate colour.

If we have any residual freed atomic state from earlier commits, flush the freed list after performing the current modeset. This prevents the freed list from ever-growing if userspace manages to starve the kernel threads (i.e. we are never able to run our free state worker and eventually the system may even oom).

The only difference for the more recent of those macros is the version of the *_reg_<read/write>_fw_domains function. Passing the function prefix in allows us to re-use the same macro to generate functions for different GENs and will make it easier to add new accessors in the future Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1486171409-21542-1-git-send-email-daniele.ceraolospurio@intel.comReviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

The current tail breaks the pattern of if (check) return false, which can catch the reader out. If we move the gen2/3 power-of-two test into the earlier gen2/3 branch, we can eliminate the contrary tail.

In commit 957870f9 ("drm/i915: Split out i915_gem_object_set_tiling()"), I swapped an alignment check for IS_ALIGNED and in the process removed the less-than check. That check turns out to be important as it was the only rejection for stride == 0. Tvrtko did spot it, but I was overconfident in the IS_ALIGNED() conversion.

If we fail to dma-map the object, the most common cause is lack of space inside the SW-IOTLB due to fragmentation. If we recreate the_sg_table using segments of PAGE_SIZE (and single page allocations), we may succeed in remapping the scatterlist. First became a significant problem for the mock selftests after commit 5584f1b1 ("drm/i915: fix i915 running as dom0 under Xen") increased the max_order.

Apparently there are machines out there with Skylake CPU and KabyPoint PCH. Judging from our driver code, there doesn't seem to be any code paths that would do anything different between SunrisePoint and KabyPoint PCHs, so it would seem okay to accept the combo without warnings. Fixes: 22dea0be ("drm/i915: Introduce Kabypoint PCH for Kabylake H/DT.")
