tasklet_kill() will spin waiting for the current tasklet to be executed. However, if tasklet_disable() has been called, then the tasklet is never executed but permanently put back onto the runlist until tasklet_enable() is called. Ergo, we cannot use tasklet_kill() inside a disable/enable pair. This is the case when we call set-wedge from inside i915_reset(), and another request was submitted to us concurrent to the reset.

Currently, we only allow ourselves to prune the fences so long as all the waits completed (i.e. all the fences we checked were signaled), and that the reservation snapshot did not change across the wait. However, if we only waited for a subset of the reservation object, i.e. just waiting for the last writer to complete as opposed to all readers as well, then we would erroneously conclude we could prune the fences as indeed although all of our waits were successful, they did not represent the totality of the reservation object. v2: We only need to check the shared fences due to construction (i.e. all of the shared fences will be later than the exclusive fence, if any).

With the introduction of asymmetric slices in CNL, we cannot rely on the previous SUBSLICE_MASK getparam to tell userspace what subslices are available. Here we introduce a more detailed way of querying the Gen's GPU topology that doesn't aggregate numbers. This is essential for monitoring parts of the GPU with the OA unit, because counters need to be normalized to the number of EUs/subslices/slices. The current aggregated numbers like EU_TOTAL do not gives us sufficient information.

There are a number of information that are readable from hardware registers and that we would like to make accessible to userspace. One particular example is the topology of the execution units (how are execution units grouped in subslices and slices and also which ones have been fused off for die recovery). At the moment the GET_PARAM ioctl covers some basic needs, but generally is only able to return a single value for each defined parameter. This is a bit problematic with topology descriptions which are array/maps of available units. This change introduces a new ioctl that can deal with requests to fill structures of potentially variable lengths. The user is expected fill a query with length fields set at 0 on the first call, the kernel then sets the length fields to the their expected values. A second call to the kernel with length fields at their expected values will trigger a copy of the data to the pointed memory locations.

Enhanced Execlists is an upgraded version of execlists which supports up to 8 ports. The lrcs to be submitted are written to a submit queue (the ExecLists Submission Queue - ELSQ), which is then loaded on the HW. When writing to the ELSP register, the lrcs are written cyclically in the queue from position 0 to position 7. Alternatively, it is possible to write directly in the individual positions of the queue using the ELSQC registers. To be able to re-use all the existing code we're using the latter method and we're currently limiting ourself to only using 2 elements. v2: Rebase. v3: Switch from !IS_GEN11 to GEN < 11 (Daniele Ceraolo Spurio). v4: Use the elsq registers instead of elsp.

Starting from Gen11 the context descriptor format has been updated in the HW. The hw_id field has been considerably reduced in size and engine class and instance fields have been added. There is a slight name clashing issue because the field that we call hw_id is actually called SW Context ID in the specs for Gen11+. With the current size of the hw_id field we can have a maximum of 2k contexts at any time, but we could use the sw_counter field (which is sw defined) to increase that because the HW requirement is that engine_id + sw id + sw_counter is a unique number. GuC uses a similar method to support more contexts but does its tracking at lrc level. To avoid doing an implementation that will need to be reworked once GuC support lands, defer it for now and mark it as TODO. v2: rebased, add documentation, fix GEN11_ENGINE_INSTANCE_SHIFT v3: rebased, bring back lost code from i915_gem_context.c v4: make TODO comment more generic v5: be consistent with bit ordering, add extra checks (Chris) Cc: Oscar Mateo <oscar.mateo@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Signed-off-by: NDaniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: NOscar Mateo <oscar.mateo@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180302161501.28594-3-mika.kuoppala@linux.intel.comSigned-off-by: NMika Kuoppala <mika.kuoppala@linux.intel.com>

LSPCON likes to throw short HPDs during the enable seqeunce prior to the link being trained. These obviously result in the channel CR/EQ check failing and thus we schedule a pointless hotplug work to retrain the link. Avoid that by ignoring the bad CR/EQ status until we've actually initially trained the link. I've not actually investigated to see what LSPCON is trying to signal with the short pulse. But as long as it signals anything I think we're supposed to check the link status anyway, so I don't really see other good ways to solve this. I've not seen these short pulses being generated by normal DP sinks.

Doing link retraining from the short pulse handler is problematic since that might introduce deadlocks with MST sideband processing. Currently we don't retrain MST links from this code, but we want to change that. So better to move the entire thing to the hotplug work. We can utilize the new encoder->hotplug() hook for this. The only thing we leave in the short pulse handler is the link status check. That one still depends on the link parameters stored under intel_dp, so no locking around that but races should be mostly harmless as the actual retraining code will recheck the link state if we end up there by mistake. v2: Rebase due to ->post_hotplug() now being just ->hotplug() Check the connector type to figure out if we should do the HDMI thing or the DP think for DDI [pushed with whitespace changes for sparse] Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Acked-by: NManasi Navare <manasi.d.navare@intel.com> Signed-off-by: NLyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180117192149.17760-3-ville.syrjala@linux.intel.com
