We're now calling intel_pipe_config_compare(..., true) uncoditionally which means we're always going clobber the calculated M/N values with the old values if the fuzzy M/N check passes. That causes problems because the fuzzy check allows for a huge difference in the values. I'm actually tempted to just make the M/N checks exact, but that might prevent fastboot from kicking in when people want it. So for now let's overwrite the computed values with the old values only if decide to skip the modeset. v2: Copy has_drrs along with M/N M2/N2 values Cc: stable@vger.kernel.org Cc: Blubberbub@protonmail.com Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Hans de Goede <hdegoede@redhat.com> Tested-by: Blubberbub@protonmail.com Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110782 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110675 Fixes: d19f958d ("drm/i915: Enable fastset for non-boot modesets.")

Though we pin the context first before taking the pm wakeref, during retire we need to unpin before dropping the pm wakeref (breaking the "natural" onion).

Currently, we perform a locked update of the shadow entry when allocating a page directory entry such that if two clients are concurrently allocating neighbouring ranges we only insert one new entry for the pair of them. However, we also need to serialise both clients wrt to the actual entry in the HW table, or else we may allow one client or even a third client to proceed ahead of the HW write. My handwave before was that under the _pathological_ condition we would see the scratch entry instead of the expected entry, causing a temporary glitch. That starvation condition will eventually show up in practice, so fix it. The reason for the previous cheat was to avoid having to free the extra allocation while under the spinlock. Now, we keep the extra entry allocated until the end instead. v2: Fix error paths for gen6 Fixes: 1d1b5490 ("drm/i915/gtt: Replace struct_mutex serialisation for allocation") Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Matthew Auld <matthew.auld@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: NMatthew Auld <matthew.auld@intel.com> Reviewed-by: NMika Kuoppala <mika.kuoppala@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190617140426.7203-1-chris@chris-wilson.co.uk

ICL introduces a new gamma correction mode in display engine, called multi-segmented-gamma mode. This mode allows users to program the darker region of the gamma curve with sueprfine precision. An example use case for this is HDR curves (like PQ ST-2084). If we plot a gamma correction curve from value range between 0.0 to 1.0, ICL's multi-segment has 3 different sections: - superfine segment: 9 values, ranges between 0 - 1/(128 * 256) - fine segment: 257 values, ranges between 0 - 1/(128) - corase segment: 257 values, ranges between 0 - 1 This patch: - Changes gamma LUTs size for ICL/GEN11 to 262144 entries (8 * 128 * 256), so that userspace can program with highest precision supported. - Changes default gamma mode (non-legacy) to multi-segmented-gamma mode. - Adds functions to program/detect multi-segment gamma. V2: Addressed review comments from Ville - separate function for superfine and fine segments. - remove enum for segments. - reuse last entry of the LUT as gc_max value. - replace if() ....cond with switch...case in icl_load_luts. - add an entry variable, instead of 'word' V3: Addressed review comments from Ville - extra newline - s/entry/color/ - remove LUT size checks - program ilk_lut_12p4_ldw value before ilk_lut_12p4_udw - Change the comments in description of fine and coarse segments, and try to make more sense. - use 8 * 128 instead of 1024 - add 1 entry in LUT for GCMAX V4: Addressed review comments from Ville - Remove unused macro - missing shift entry in blue - pick correct entry for GCMAX - Added Ville's R-B Note: Tested and confirmed the programming sequence of odd/even registers in the HW. The correct sequence should be: ilk_lut_12p4_udw ilk_lut_12p4_ldw v5: Addressed Ville's review comments and renamed odd/even register helpers to be more consistent with the values.

We need to keep the context image pinned in memory until after the GPU has finished writing into it. Since it continues to write as we signal the final breadcrumb, we need to keep it pinned until the request after it is complete. Currently we know the order in which requests execute on each engine, and so to remove that presumption we need to identify a request/context-switch we know must occur after our completion. Any request queued after the signal must imply a context switch, for simplicity we use a fresh request from the kernel context. The sequence of operations for keeping the context pinned until saved is: - On context activation, we preallocate a node for each physical engine the context may operate on. This is to avoid allocations during unpinning, which may be from inside FS_RECLAIM context (aka the shrinker) - On context deactivation on retirement of the last active request (which is before we know the context has been saved), we add the preallocated node onto a barrier list on each engine - On engine idling, we emit a switch to kernel context. When this switch completes, we know that all previous contexts must have been saved, and so on retiring this request we can finally unpin all the contexts that were marked as deactivated prior to the switch. We can enhance this in future by flushing all the idle contexts on a regular heartbeat pulse of a switch to kernel context, which will also be used to check for hung engines. v2: intel_context_active_acquire/_release Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: NMika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190614164606.15633-1-chris@chris-wilson.co.uk

The functions where internally already only using the structure, so we need to just flip the interface. v2: rebase Signed-off-by: NDaniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Imre Deak <imre.deak@intel.com> Reviewed-by: NChris Wilson <chris@chris-wilson.co.uk> Acked-by: NImre Deak <imre.deak@intel.com> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190613232156.34940-7-daniele.ceraolospurio@intel.com

Asserts aside, all the code working on this structure is in intel_runtime_pm.c and uses the intel_ prefix, so move the structure to intel_runtime_pm.h and adopt the same prefix. Since all the asserts are now working on the runtime_pm structure, bring them across as well. v2: drop unneeded include (Chris), don't rename debugfs, rebase Signed-off-by: NDaniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Imre Deak <imre.deak@intel.com> Reviewed-by: NChris Wilson <chris@chris-wilson.co.uk> Acked-by: NImre Deak <imre.deak@intel.com> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190613232156.34940-5-daniele.ceraolospurio@intel.com
