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.

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: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191030190815.7359-1-ville.syrjala@linux.intel.comTested-by: NHans de Goede <hdegoede@redhat.com> Reviewed-by: NHans de Goede <hdegoede@redhat.com>

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.

由 Daniel Vetter 提交于
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.

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).
