As the GTT is outside of the powerwell, we can simplify flushing the GGTT writes by using an unchecked mmio write and post. v2: s/unc/uncore/ Signed-off-by:

As the fence registers are not part of the engine powerwells, we do not need to fiddle with forcewake in order to update a fence. Avoid using the heavyweight debug checking normal mmio writes as the checking dominates the selftest runtime and is superfluous! In the process, retire the I915_WRITE() implicit macro with the new intel_uncore_write interface. v2: s/unc/uncore/ Signed-off-by:

We only need to flush the object once prior to starting the partial tiling test as inside the test we explicitly maintain coherency. Signed-off-by:

Stop dumping plane->state for planes. That is the old state most of the time and dumping stale information only serves to confuse people. Instead dump the new state just for the planes included in the operation. For now we'll include only the planes for the modeset/fastset pipes in the dumps. But probably we want to dump them all eventually, just not quite sure how to present that information nicely to the user. And while at it let's dump a few more interesting bits from the state.

Currently we're only dumping the failed crtc state if intel_modeset_pipe_config() fails. Let's do the state dump if anything else fails afterwards. The downside is that we lose the immediate knowledge which crtc caused the failure (unless a lower level function indicates it with an additional debug print) but having the full state dumped seems like something that could be beneficial.

Currently we're not dumping out whether the crtc is actually active or in dpms off state. Let's include that in the dumps. And while at it compress out a few lines from the state dump. Signed-off-by:

Ville Syrjälä authored
Currently we're dumping the crtc states before they have been fully calculated. Move the dumping to the end of .atomic_check() so we get a fully up to date dump. Let's also do the dump for fully disabled pipes, but we'll limit that to just saying that the pipe is disabled since the rest of the state is going to be nonsense in that case. Signed-off-by:

Keep all the device-level PM management in intel_runtime_pm.h/c and move all the display specific bits into their own file. Also add the new header to Makefile.header-test. Apart from the giant code move, the only difference is with the intel_runtime_<get/put>_raw() functions, which are now exposed in the header. The _put() version is also not conditionally compiled anymore since it is ok to always pass the wakeref taken from the _get() to __intel_runtime_pm_put (it is -1 if tracking is disabled).

Make sure the HW state of the port A combo PHY is correct wrt. the IREFGEN setting. This will force a reprogramming during init or a WARN during uninit if the setting is incorrect. On my ICL RVP I haven't seen this check failing and leading to a forced reinit/WARN, but let's add it still for consistency. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Currently, we try to report to the shrinker the precise number of objects (pages) that are available to be reaped at this moment. This requires searching all objects with allocated pages to see if they fulfill the search criteria, and this count is performed quite frequently. (The shrinker tries to free ~128 pages on each invocation, before which we count all the objects; counting takes longer than unbinding the objects!) If we take the pragmatic view that with sufficient desire, all objects are eventually reapable (they become inactive, or no longer used as framebuffer etc), we can simply return the count of pinned pages maintained during get_pages/put_pages rather than walk the lists every time. The downside is that we may (slightly) over-report the number of objects/pages we could shrink and so penalize ourselves by shrinking more than required. This is mitigated by keeping the order in which we shrink objects such that we avoid penalizing active and frequently used objects, and if memory is so tight that we need to free them we would need to anyway. v2: Only expose shrinkable objects to the shrinker; a small reduction in not considering stolen and foreign objects. v3: Restore the tracking from a "backup" copy from before the gem/ split Signed-off-by:

Currently the purgeable objects, I915_MADV_DONTNEED, are mixed in the normal bound/unbound lists. Every shrinker pass starts with an attempt to purge from this set of unneeded objects, which entails us doing a walk over both lists looking for any candidates. If there are none, and since we are shrinking we can reasonably assume that the lists are full!, this becomes a very slow futile walk. If we separate out the purgeable objects into own list, this search then becomes its own phase that is preferentially handled during shrinking. Instead the cost becomes that we then need to filter the purgeable list if we want to distinguish between bound and unbound objects. Signed-off-by:

The i915.alpha_support module parameter has caused some confusion along the way. Add new i915.force_probe parameter to specify PCI IDs of devices to probe, when the devices are recognized but not automatically probed by the driver. The name is intended to reflect what the parameter effectively does, avoiding any overloaded semantics of "alpha" and "support". The parameter supports "" to disable, "<pci-id>,[<pci-id>,...]" to enable force probe for one or more devices, and "*" to enable force probe for all known devices. Also add new CONFIG_DRM_I915_FORCE_PROBE config option to replace the DRM_I915_ALPHA_SUPPORT option. This defaults to "*" if DRM_I915_ALPHA_SUPPORT=y. Instead of replacing i915.alpha_support immediately, let the two coexist for a while, with a deprecation message, for a transition period.

The normal behaviour is to periodically check for a mmio access error, and once detected enable mmio access checking. However this is useless if the error only occurs once during module load, and so we may miss such errors in CI. To allow ourselves to catch them, allow CI to opt into always enabling mmio debugging.

In order to support driver hot unbind, some cleanup operations, now performed on PCI driver remove, must be called later, after all device file descriptors are closed. Split out those operations from the tail of pci_driver.remove() callback and put them into drm_driver.release() which is called as soon as all references to the driver are put. As a result, those cleanups will be now run on last drm_dev_put(), either still called from pci_driver.remove() if all device file descriptors are already closed, or on last drm_release() file operation.

The plan is to use the blitter engine for async object clearing when using local memory, but before we can move the worker to get_pages() we have to first tame some more of our struct_mutex usage. With this in mind we should be able to upstream the object clearing as some selftests, which should serve as a guinea pig for the ongoing locking rework and upcoming async get_pages() framework.

An interesting issue cropped with making the pagetables be allocated and freed concurrently (i.e. removing their grandeous struct_mutex guard) was that we would overflow the page stash. This happens when we have multiple allocators grabbing WC pages such that we fill the vm's local page stash and then when we free another page, the page stash is already full and we overflow. The fix is quite simple: to check for a full page stash before adding another. This results in us keeping a vm local page stash around for much longer, which is both a blessing and a curse.

This reverts commit 1ac159e2 ("drm/i915: Expand subslice mask"), which kills ICL due to GEM_BUG_ON() sanity checks before CI even gets a chance to do anything. The commit exposes an issue in commit 1e40d4ae ("drm/i915/cnl: Implement WaProgramMgsrForCorrectSliceSpecificMmioReads"), which will also need to be addressed. There's a proposed fix [1], but considering the seeming uncertainty with the fix as well as the size of the regressing commit (in this context, the one that actually brings down ICL), this warrants a revert to get ICL working, and gives us time to get all of this right without rushing.
