2020-04-17drm/i915/selftests: Check power consumption at min/max frequenciesChris Wilson
A basic premise of RPS is that at lower frequencies, not only do we run slower, but we save power compared to higher frequencies. For example, when idle, we set the minimum frequency just in case there is some residual current. Since the power curve should be a physical relationship, if we find no power saving it's likely that we've broken our frequency handling, so test!

It seems that although (perhaps because of the memory stall?) the spinner has signaled that it has started, it still takes some time to spin up to 100% utilisation of the HW. Since the test depends on the full utilisation of the HW to trigger the RPS interrupt, wait a little bit and flush the interrupt status to be sure that the event we see if from the spinner.

Before we resume, we reset the HW so we restart from a known good state. However, as a part of the reset process, we drain our pending CS event queue -- and if we are resuming that does not correspond to internal state. On setup, we are scrubbing the CS pointers, but alas only on setup. Apply the sanitization not just to setup, but to all resumes.

2020-04-17drm/i915/gvt: skip populate shadow context if guest context not changedYan Zhao
Software is not expected to populate engine context except when using restore inhibit bit or golden state to initialize it for the first time. Therefore, if a newly submitted guest context is the same as the last shadowed one, no need to populate its engine context from guest again. Currently using lrca + ring_context_gpa to identify whether two guest contexts are the same. The reason of why context id is not included as an identifier is that i915 recently changed the code and context id is only unique for a context when OA is enabled. And when OA is on, context id is generated based on lrca. Therefore, in that case, if two contexts are of the same lrca, they have identical context ids as well. (This patch also works with old guest kernel like 4.20.) for guest context, if its ggtt entry is modified after last context shadowing, it is also deemed as not the same context as last shadowed one. v7: -removed local variable "valid". use the one in s->last_ctx diretly v6: -change type of lrca of last ctx to be u32. as currently it's all protected by vgpu lock (Kevin Tian) -reset valid of last ctx to false once it needs to be repopulated before population completes successfully (Kevin Tian) v5: -merge all 3 patches into one patch (Zhenyu Wang) v4: - split the series into 3 patches. - don't turn on optimization until last patch in this series (Kevin Tian) - define lrca to be atomic in this patch rather than update its type in the second patch (Kevin Tian) v3: updated commit message to describe engine context and context id clearly (Kevin Tian) v2: rebased to 5.6.0-rc4+Signed-off-by: Yan Zhao <yan.y.zhao@intel.com> Reviewed-by: Zhenyu Wang <zhenyuw@linux.intel.com> Reviewed-by: Kevin Tian <kevin.tian@intel.com> Cc: Kevin Tian <kevin.tian@intel.com> Suggested-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Yan Zhao <yan.y.zhao@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20200417091334.32628-1-yan.y.zhao@intel.com

2020-04-14drm/i915: Start passing latency as parameterStanislav Lisovskiy
We need to start passing memory latency as a parameter when calculating plane wm levels, as latency can get changed in different circumstances(for example with or without SAGV). So we need to be more flexible on that matter. v2: Changed latency type from u32 to unsigned int(Ville Syrjälä) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200409154730.18568-2-stanislav.lisovskiy@intel.com
2020-04-14drm/i915: do AUD_FREQ_CNTRL state save on all gen9+ platformsKai Vehmanen
Replace the TGL/ICL specific platform checks with a more generic check using INTEL_GEN(). Fixes bug with broken audio after S3 resume on JSL platforms. An initial version of state save and restore of AUD_FREQ_CNTRL register was added for subset of platforms in commit 87c1694533c9 ("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend"). The state save has proven to work well and it is needed in newer platforms, so needs to be extended. Although the logic is not in practise needed on GEN9/10 systems, follow the hardware specification and apply state and restore on all gen9+ platforms.

2020-04-10mm/vma: introduce VM_ACCESS_FLAGSAnshuman Khandual
There are many places where all basic VMA access flags (read, write, exec) are initialized or checked against as a group. One such example is during page fault. Existing vma_is_accessible() wrapper already creates the notion of VMA accessibility as a group access permissions. Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which will not only reduce code duplication but also extend the VMA accessibility concept in general.

2020-04-10agp/intel: Reinforce the barrier after GTT updatesChris Wilson
After changing the timing between GTT updates and execution on the GPU, we started seeing sporadic failures on Ironlake. These were narrowed down to being an insufficiently strong enough barrier/delay after updating the GTT and scheduling execution on the GPU. By forcing the uncached read, and adding the missing barrier for the singular insert_page (relocation paths), the sporadic failures go away.
