printks are slow so we should not be doing them from the vblank evade critical section. These could explain why we sometimes seem to blow past our 100 usec deadline. The problem has been there ever since commit bfd16b2a ("drm/i915: Make updating pipe without modeset atomic.") but it may not have been readily visible until commit e1edbd44 ("drm/i915: Complain if we take too long under vblank evasion.") increased our chances of noticing it.

Backmerge drm-next to get at all the good stuff in drm-misc. We need that because: - drm_connector_list_iter conversion for i915 needs the core patches. - Maarten's patches to use the new atomic state iterators also need the core patches. - We need the new link status property to complete the DP retraining work, merging through 2 branches wasn't a good idea and we had to partially backtrack. - Chris needs reservation_object_trylock and we want to roll out kref_read everywhere.

4 weeks worth of stuff since I was traveling&lazy: - lspcon improvements (Imre) - proper atomic state for cdclk handling (Ville) - gpu reset improvements (Chris) - lots and lots of polish around fences, requests, waiting and everything related all over (both gem and modeset code), from Chris - atomic by default on gen5+ minus byt/bsw (Maarten did the patch to flip the default, really this is a massive joint team effort) - moar power domains, now 64bit (Ander) - big pile of in-kernel unit tests for various gem subsystems (Chris), including simple mock objects for i915 device and and the ggtt manager. - i915_gpu_info in debugfs, for taking a snapshot of the current gpu state.

Before we instantiate/pin the backing store for our use, we can prepopulate the shmemfs filp efficiently using a write into the pagecache. We avoid the penalty of instantiating all the pages, important if the user is just writing to a few and never uses the object on the GPU, and using a direct write into shmemfs allows it to avoid the cost of retrieving a page (mostly the clear-before-use, but in theory we could curtail swapin) before it is overwritten. This can be extended later to provide additional specialisation for other backends (other than shmemfs). For now it provides a defense against very large write-only allocations from exhausting all of system memory. v2: Smelling fixes.

Once the object has been truncated, it is unrecoverable. To facilitate detection of this state store the error in obj->mm.pages. This is required for the next patch which should be applied to v4.10 (via stable), so we also need to mark this patch for backporting. In that regard, let's consider this to be a fix/improvement too. v2: Avoid dereferencing the ERR_PTR when freeing the object.

The IS_G4X macro is defined as IS_G45 || IS_GM45. We have two points in our code where we have an if statement checking for GM45 followed by an else if statement checking for IS_G4X. This can be confusing since the IS_G4X check won't be catching the previously-checked GM45. Someone quickly trying to check which functions run on each platform may end up getting confused while reading the code. Fix the potential confusion by limiting the else if statements to only check for the platform that was not already checked earlier in the if ladder. Signed-off-by:

In order for the missed-irq update to take effect, the device must be idle. So when the user updates the fault injection via debugfs, idle the device. v2: Idle is explicitly required for setting test_irq, and good behaviour for clearing the missed_irq. v3: Use matching types; expanding to more than ulong rings is left as an exercise to the reader.

This commit reworks the RAM detection algorithm, using RAM-per-LTC to determine whether a board has a mixed-memory configuration instead of using RAM-per-FBPA. I'm not certain the algorithm is perfect, but it should handle all currently known configurations in the very least. This should fix GTX 970 boards with 4GiB of RAM where the last 512MiB isn't fully accessible, as well as only detecting half the VRAM on GF108 boards. As a nice side-effect, GP10x memory detection now reuses the majority of the code from earlier chipsets. Signed-off-by:Ben Skeggs <bskeggs@redhat.com>

I had the brilliant idea to "improve" the binary format by removing a useless indirection in the HS binary files. In the end it just makes things more complicated than they ought to be as NVIDIA-provided files need to be adapted. Since the format used can be identified by the header, support both. Signed-off-by:

Alexandre Courbot authored
Since the HS blobs are provided and signed by NVIDIA, we cannot expect always-consistent behavior. In this case, on GP10x the unload blob may return 0x1d even though things have run perfectly well. This behavior has been confirmed by NVIDIA. So let the callers of the run_blob() hook receive the blob return's value (a positive integer) and decide what it means. This allows us to workaround the 0x1d code instead of issuing an error. Signed-off-by:
