Since drm provided us with a real struct file we can use for our anonymous internal clients (mock_file), complete our transition to using that as the primary interface (and not the mocked up struct drm_file we previous were using). Signed-off-by:

Rather than just specifying the bullet numbers from the bspec (e.g., "4.b") actually include the description of what the bspec wants us to do. Steps can be renumbered or moved so including the description will help us match the code up to the spec. Plus if we add support for new platforms, some of the steps may be added/removed so more descriptive comments will be useful for ensuring all of the bspec requirements are met.

Whenever, we unbind (or change fence registers) on an object, we must revoke any and all mmap_gtt using the previous bindings. Those user PTEs point at the GGTT which know points into a new object, the wrong object. Ergo, those PTEs must be cleared so that any user access provokes a new page fault. Signed-off-by:

As drm now exports a method to create an anonymous struct file around a drm_device for internal use, make use of it to avoid our horrible hacks. Danial suggested that the mock_file_put() wrapper was suitable for drm-core, along with the mock_drm_getfile() [and that the vestigal mock_drm_file() in this patch should perhaps be the drm interface itself]. However, the eventual goal is to remove the mock_drm_file() and use the struct file and fput() directly, in this patch we take a simple transition in that direction. Signed-off-by:

Currently, we only export symbols for drm-selftests which are either compiled as modules or into the main drm builtin. However, if we want to export symbols from drm.ko for the drivers' selftests, we require a means of controlling that export separately. So we add a new Kconfig to determine whether or not the EXPORT_SYMBOL_FOR_TESTS_ONLY() takes effect. Signed-off-by:

The LUTs are single buffered so in order to program them without tearing we'd have to do it during vblank (actually to be 100% effective it has to happen between start of vblank and frame start). We have no proper mechanism for that at the moment so we just defer loading them after the vblank waits have happened. That is not quite sufficient (especially when committing multiple pipes whose vblanks don't line up) so the LUT load will often leak into the following frame causing tearing. However in case the hardware wasn't previously using the LUT we can preload it before setting the enable bit (which is double buffered so won't tear). Let's determine if we can do such preloading and make it happen. Slight variation between the hardware requires some platforms specifics in the checks. Hans is seeing ugly colored flash on VLV/CHV macchines (GPD win and Asus T100HA) when the gamma LUT gets loaded for the first time as the BIOS has left some junk in the LUT memory. v2: Deal with uapi vs. hw crtc state split s/GCM/CGM/ typo fix Cc: Hans de Goede <hdegoede@redhat.com> Fixes: 051a6d8d ("drm/i915: Move LUT programming to happen after vblank waits") Signed-off-by:

So strictly speaking the existing annotation is also ok, because we have a chain of obj->mm.lock#I915_MM_GET_PAGES -> fs_reclaim -> obj->mm.lock (the shrinker cannot get at an object while we're in get_pages, hence this is safe). But it's confusing, so try to take the right subclass of the lock. This does a bit reduce our lockdep based checking, but then it's also less fragile, in case we ever change the nesting around.

Daniel Vetter authored
The trouble with having a plain nesting flag for locks which do not naturally nest (unlike block devices and their partitions, which is the original motivation for nesting levels) is that lockdep will never spot a true deadlock if you screw up. This patch is an attempt at trying better, by highlighting a bit more of the actual nature of the nesting that's going on. Essentially we have two kinds of objects: - objects without pages allocated, which cannot be on any lru and are hence inaccessible to the shrinker. - objects which have pages allocated, which are on an lru, and which the shrinker can decide to throw out. For the former type of object, memory allocations while holding obj->mm.lock are permissible. For the latter they are not. And get/put_pages transitions between the two types of objects. This is still not entirely fool-proof since the rules might change. But as long as we run such a code ever at runtime lockdep should be able to observe the inconsistency and complain (like with any other lockdep class that we've split up in multiple classes). But there are a few clear benefits: - We can drop the nesting flag parameter from __i915_gem_object_put_pages, because that function by definition is never going allocate memory, and calling it on an object which doesn't have its pages allocated would be a bug. - We strictly catch more bugs, since there's not only one place in the entire tree which is annotated with the special class. All the other places that had explicit lockdep nesting annotations we're now going to leave up to lockdep again. - Specifically this catches stuff like calling get_pages from put_pages (which isn't really a good idea, if we can call get_pages so could the shrinker). I've seen patches do exactly that. Of course I fully expect CI will show me for the fool I am with this one here :-) v2: There can only be one (lockdep only has a cache for the first subclass, not for deeper ones, and we don't want to make these locks even slower). Still separate enums for better documentation. Real fix: don't forget about phys objs and pin_map(), and fix the shrinker to have the right annotations ... silly me. v3: Forgot usertptr too ... v4: Improve comment for pages_pin_count, drop the IMPORTANT comment and instead prime lockdep (Chris). v5: Appease checkpatch, no double empty lines (Chris) v6: More rebasing over selftest changes. Also somehow I forgot to push this patch :-/ Also format comments consistently while at it. v7: Fix typo in commit message (Joonas) Also drop the priming, with the lmem merge we now have allocations while holding the lmem lock, which wreaks the generic priming I've done in earlier patches. Should probably be resurrected when lmem is fixed.

If the device does not have an aperture through which we can indirectly access and detile the buffers, simply reject the ioctl. Later we can extend the ioctl to support different modes, but as an extension the user must opt in and explicitly control the mmap type (viz MMAP_OFFSET_IOCTL). Signed-off-by:

It sounds like the hardware only needs the DSB object to be in global GTT and not in the mappable region. Signed-off-by:

Split out the DP specific parts, making it easier to add DSI specific configuration. Also move the encoder specific parts towards the end, to allow overriding generic configuration if needed. This also improves clarity by making it clear the encoder independent configuration does not depend on the encoder specific parts. v2: Rebase Cc: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by:

Since CNP it's possible for rawclk to have two different values, 19.2 and 24 MHz. If the value indicated by SFUSE_STRAP register is different from the power on default for PCH_RAWCLK_FREQ, we'll end up having a mismatch between the rawclk hardware and software states after suspend/resume. On previous platforms this used to work by accident, because the power on defaults worked just fine. Update the rawclk also on resume. The natural place to do this would be intel_modeset_init_hw(), however VLV/CHV need it done before intel_power_domains_init_hw(). Thus put it there even if it feels slightly out of place. v2: Call intel_update_rawclck() in intel_power_domains_init_hw() for all platforms (Ville). Reported-by:

For MST on Tiger Lake there are different moments when we need to configure the transcoder clock select. For the first link this is in step 7.a of the spec, before training the link. For additional streams this should be done as part of step 8.b after programming receiver VC Payload ID. Bspec: 49190 Signed-off-by:
