uC is a component of the GT, so it makes sense for the uC debugfs files to be in the GT folder. A subfolder has been used to keep the same structure we have for the code. v2: use intel_* prefix (Jani), rebase on new gt_debugfs_register_files, fix permissions for writable debugfs files. v3: Rename files (Michal), remove blank line (Jani), fix sparse warns.

Move the printers to the respective files for clarity. The guc_load_status debugfs has been squashed in the guc_info one, has having separate ones wasn't very useful. The HuC debugfs has been renamed huc_info to match. v2: keep printing HUC_STATUS2 (Tony), avoid const->non-const container_of (Jani) Suggested-by:Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by:

We currently initialize HuC support based on GuC being enabled in modparam; this means that huc_is_supported() can return false on HW that does have a HuC when enable_guc=0. The rationale for this behavior is that HuC requires GuC for authentication and therefore is not supported by itself. However, we do not allow defining HuC fw wthout GuC fw and selecting HuC in modparam implicitly selects GuC as well, so we can't actually hit a scenario where HuC is selected alone. Therefore, we can flip the support check to reflect the HW capabilities and fw availability, which is more intuitive and will make it cleaner to log HuC the difference between not supported in HW and not selected. Removing the difference between GuC and HuC also allows us to simplify the init_early, since we don't need to differentiate the support based on the type of uC. Signed-off-by:

The pool will be private to GuC in the new submission scheme, so we won't be able to print it and we can just drop the current legacy code. Signed-off-by:

When registering debugfs files the intel gt debugfs library forces a 'struct *gt' private data on the caller. To be open to different usages make the new "intel_gt_debugfs_register_files()"[*] function more generic by converting the 'struct *gt' pointer to a 'void *' type. I take the chance to rename the functions by using "intel_gt_" as prefix instead of "debugfs_", so that "debugfs_gt_register_files()" becomes "intel_gt_debugfs_register_files()". Signed-off-by:

This patch fixes the private_flags of mode to be checked and compared against uapi.mode and not from hw.mode. This helps properly trigger modeset at boot if desired by driver. It helps resolve audio_codec initialization issues if display is connected at boot. Initial discussion on this issue has happened on below thread: https://patchwork.freedesktop.org/series/74828/ v2: No functional change. Fixed the Closes tag and added Maarten's RB. v3: Added Fixes tag.

We move the virtual breadcrumb from one physical engine to the next, if the next virtual request is scheduled on a new physical engine. Since the virtual context can only be in one signal queue, we need it to track the current physical engine for the new breadcrumbs. However, to move the list we need both breadcrumb locks -- and since we cannot take both at the same time (unless we are careful and always ensure consistent ordering) stage the movement of the signaler via the current virtual request.

If the caller allows and we do not have to wait for any signals, immediately execute the work within the caller's process. By doing so we avoid the overhead of scheduling a new task, and the latency in executing it, at the cost of pulling that work back into the immediate context. (Sometimes we still prefer to offload the task to another cpu, especially if we plan on executing many such tasks in parallel for this client.) Signed-off-by:

We dropped calling process_csb prior to handling direct submission in order to avoid the nesting of spinlocks and lift process_csb() and the majority of the tasklet out of irq-off. However, we do want to avoid ksoftirqd latency in the fast path, so try and pull the interrupt-bh local to direct submission if we can acquire the tasklet's lock. v2: Document the read of pending[0] from outside the tasklet with READ_ONCE.

Measure and compare the energy consumed, as reported by the rapl MSR, by the GPU while in RC0 and RC6 states. Throw an error if RC6 does not at least halve the energy consumption of RC0, as this more than likely means we failed to enter RC0 correctly. If we can't measure the energy draw with the MSR, then it will report 0 for both measurements. Since the measurement works on all gen6+, this seems worth flagging as an error. Signed-off-by:

We set the priority hint on execlists to avoid executing the tasklet for when we know that there will be no change in execution order. However, as we set it from the virtual engine for all siblings, but only one physical engine may respond, we leave the hint set on the others stopping direct submission that could take place. If we do not set the hint, we may attempt direct submission even if we don't expect to submit. If we set the hint, we may not do any submission until the tasklet is run (and sometimes we may park the engine before that has had a chance). Ergo there's only a minor ill-effect on mixed virtual/physical engine workloads where we may try and fail to do direct submission more often than required. (Pure virtual / engine workloads will have redundant tasklet execution suppressed as normal.) Closes: https://gitlab.freedesktop.org/drm/intel/issues/1522Signed-off-by:

dGFX has local memory so it does not have aperture or support CPU fences but even for iGFX it have a small number of fences. As replacement for fences to track frontbuffer modifications by CPU we have a software tracking that is already in used by FBC and PSR. PSR don't support fences so it shows that this tracking is reliable. So lets make fences a nice-to-have to activate FBC for GEN9+, this will allow us to enable FBC for dGFXs and iGFXs even when there is no available fence. We do not set fences to rotated planes but FBC only have restrictions against 16bpp, so adding it here. Also adding a new check for the tiling format, fences are only set to X and Y tiled planes but again FBC don't have any restrictions against tiling so adding linear as supported as well, other formats should be added after tested but IGT only supports drawing in thse 3 formats. intel_fbc_hw_tracking_covers_screen() maybe can also have the same treatment as fences but BSpec is not clear if the size limitation is for hardware tracking or general use of FBC and I don't have a 5K display to test it, so keeping as is for safety. v2: - Added tiling and pixel format rotation checks - Changed the GEN version not requiring fences to 11 from 9, DDX needs some changes but it don't have support for GEN11+ v3: - Changed back to GEN9+ - Moved GEN test to inside of tiling_is_valid() v4: - moved rotation check to its own functions v5: - renamed rotations_is_valid to rotation_is_valid - moved pre-g4x rotation check to rotation_is_valid() Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

On Ivybridge, we can go lower than rc6 to rc6p. And this is required for Ivybridge to hit the same minimum power consumption as rc6 on other platforms, so make it so. v2: Update selftest to include all rc6 residency counters Note that Andi did mention that we should be converting the magic numbers into opaque magic macros, so if they ever get reused (unlikely given only Ivybridge used the extra modes) we'll need to pay back the technical debt.

It is strictly sufficient to only delay the intel_engine_pm_put from the context barrier (and not from the context exit) in order to prevent the gem_exec_nop contention. Adding the delay to the context exit incurs noticably extra penalty for soft-rc6.

It looks like some callers expect a non-volatile object, that they do not want the contents of the pages lost if they happen to not be looking at it. The shrinker however sees that we mark the pages as DONTNEED and believes that it can freely reap them. However, since the huge object use plain pages, they cannot be swapped out as they have no backing storge, and the only way we can shrink them is by discarding the contents. In light of the callers wanting to keep the contents around, both IS_SHRINKABLE and marking the pages as volatile are incorrect. If we drop the IS_SHRINKABLE flag we avoid the immediate issue of the shrinker accidentally removing valuable content. We will have to remember that a huge object is not suitable for exercising the shrinker interaction -- although we can introduce a shrinkable one if we require. Signed-off-by:

Keep the engine-pm awake until the next jiffie, to avoid immediate ping-pong under moderate load. (Forcing the idle barrier excerbates the moderate load, dramatically increasing the driver overhead.) On the other hand, delaying the idle-barrier slightly incurs longer rc6-off and so more power consumption. Closes: https://gitlab.freedesktop.org/drm/intel/issues/848Signed-off-by:
