2022-11-10drm/i915: Partial abandonment of legacy DRM logging macrosTvrtko Ursulin19-81/+117
Convert some usages of legacy DRM logging macros into versions which tell us on which device have the events occurred. v2: * Don't have struct drm_device as local. (Jani, Ville) v3: * Store gt, not i915, in workaround list.

2022-11-10drm/i915: Create resized LUTs for ivb+ split gamma modeVille Syrjälä1-17/+64
Currently when opeating in split gamma mode we do the "skip ever other sw LUT entry" trick in the low level LUT programming/readout functions. That is very annoying and a big hinderance to revamping the color management uapi. Let's get rid of that problem by making half sized copies of the software LUTs and plugging those into the internal {pre,post}_csc_lut attachment points (instead of the sticking the uapi provide sw LUTs there directly). With this the low level stuff will operate purely in terms the hardware LUT sizes, and all uapi nonsense is contained to the atomic check phase. The one thing we do lose is intel_color_assert_luts() since we no longer have a way to check that the uapi LUTs were correctly used when generating the internal copies. But that seems like a price worth paying.

2022-11-09drm/i915: use i915_sg_dma_sizes() for all backendsMatthew Auld14-40/+20
We rely on page_sizes.sg in setup_scratch_page() reporting the correct value if the underlying sgl is not contiguous, however in get_pages_internal() we are only looking at the layout of the created pages when calculating the sg_page_sizes, and not the final sgl, which could in theory be completely different. In such a situation we might incorrectly think we have a 64K scratch page, when it is actually only 4K or similar split over multiple non-contiguous entries, which could lead to broken behaviour when touching the scratch space within the padding of a 64K GTT page-table. For most of the other backends we already just call i915_sg_dma_sizes() on the final mapping, so rather just move that into __i915_gem_object_set_pages() to avoid such issues coming back to bite us later. v2: Update missing conversion in gvt Suggested-by: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Stuart Summers <stuart.summers@intel.com> Cc: Andrzej Hajda <andrzej.hajda@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221108103238.165447-1-matthew.auld@intel.com

2022-11-08drm/i915/ttm: fix uaf with lmem_userfault_list handlingMatthew Auld1-3/+3
In the fault handler, make sure we check if the BO maps lmem after we schedule the migration, since the current resource might change from lmem to smem, if the pages are in the non-cpu visible portion of lmem. This then leads to adding the object to the lmem_userfault_list even though the current resource is no longer lmem. If we then destroy the object, the list might still contain a link to the now free object, since we only remove it if the object is still in lmem.

2022-11-07drm/i915/psr: Send update also on invalidateJouni Högander1-1/+4
Currently we are observing mouse cursor stuttering when using xrandr --scaling=1.2x1.2. X scaling/transformation seems to be doing fronbuffer rendering. When moving mouse cursor X seems to perform several invalidates and only one DirtyFB. I.e. it seems to be assuming updates are sent to panel while drawing is done. Earlier we were disabling PSR in frontbuffer invalidate call back (when drawing in X started). PSR was re-enabled in frontbuffer flush callback (dirtyfb ioctl). This was working fine with X scaling/transformation. Now we are just enabling continuous full frame (cff) in PSR invalidate callback. Enabling cff doesn't trigger any updates. It just configures PSR to send full frame when updates are sent. I.e. there are no updates on screen before PSR flush callback is made. X seems to be doing several updates in frontbuffer before doing dirtyfb ioctl. Fix this by sending single update on every invalidate callback.

2022-11-04drm/i915/guc: Don't deadlock busyness stats vs resetJohn Harrison4-4/+21
The engine busyness stats has a worker function to do things like 64bit extend the 32bit hardware counters. The GuC's reset prepare function flushes out this worker function to ensure no corruption happens during the reset. Unforunately, the worker function has an infinite wait for active resets to finish before doing its work. Thus a deadlock would occur if the worker function had actually started just as the reset starts. The function being used to lock the reset-in-progress mutex is called intel_gt_reset_trylock(). However, as noted it does not follow standard 'trylock' conventions and exit if already locked. So rename the current _trylock function to intel_gt_reset_lock_interruptible(), which is the behaviour it actually provides. In addition, add a new implementation of _trylock and call that from the busyness stats worker instead. v2: Rename existing trylock to interruptible rather than trying to preserve the existing (confusing) naming scheme (review comments from Tvrtko).

2022-11-04drm/i915/guc: Remove excessive line feeds in state dumpsJohn Harrison2-6/+6
Some of the GuC state dump messages were adding extra line feeds. When printing via a DRM printer to dmesg, for example, that messes up the log formatting as it loses any prefixing from the printer. Given that the extra line feeds are just in the middle of random bits of GuC state, there isn't any real need for them. So just remove them completely.

2022-11-04drm/i915/userptr: restore probe_range behaviourMatthew Auld1-2/+3
The conversion looks harmless, however the addr value is updated inside the loop with the previous vm_end, which then incorrectly leads to for_each_vma_range() iterating over stuff outside the range we care about. Fix this by storing the end value separately. Also fix the case where the range doesn't intersect with any vma, or if the vma itself doesn't extend the entire range, which must mean we have hole at the end. Both should result in an error, as per the previous behaviour. v2: Fix the cases where the range is empty, or if there's a hole at the end of the range Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/7247 Testcase: igt@gem_userptr_blits@probe Fixes: f683b9d61319 ("i915: use the VMA iterator") Reported-by: kernel test robot <oliver.sang@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Matthew Wilcox (Oracle) <willy@infradead.org> Cc: Liam R.

2022-11-03drm/i915: Share {csc,gamma}_enable calculation for ilk/snb vs. ivb+Ville Syrjälä1-17/+32
ilk/snb vs. ivb+ hardware is mostly identical except for the addition of the split gamma mode on ivb. Thus we can share the csc_enable and gamma_enable calculation for both variants. Pull that stuff into a few helpers. Note that this also fills in the missing ctm/degamma stuff into ilk_color_check() pretty much, so for good measure let's also add a few extra checks relating to that, although we still don't expose ctm/degamma to userspace. But now it'll be trivial to do so if we wish.
