| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When creating a handle, it is just that, an abstract handle. The fact that we cannot currently support a handle larger than the size of the backing storage is an artifact of our whole-object-at-a-time handling in get_pages() and being an implementation limitation is best handled at that point -- similar to shmem, where we only barf when asked to populate the whole object if larger than RAM. (Pinning the whole object at a time is major hindrance that we are likely to have to overcome in the near future.) In the case of the buddy allocator, the late check is preferable as the request size may often be smaller than the required size.

The 'mmap offset' nomenclature comes from the value returned by this ioctl which is the offset into the device fd which userpace uses with mmap(2). mmap_gtt was our initial mmap_offset implementation, this extends our CPU mmap support to allow additional fault handlers that depends on the object's backing pages. Note that we multiplex mmap_gtt and mmap_offset through the same ioctl, and use the zero extending behaviour of drm to differentiate between them, when we inspect the flags. To support multiple mmap types on an object we need to support multiple mmap_offsets for an object (each offset in the global device address space corresponding to a unique instance of the object for a file + mmap type). As we drop the simplified drm core idea of a single mmap_offset, we need to provide replacement hooks for the dumb mmap interface as well.

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.

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.

This allows clients to operate in a 'fire-and-forget' manner where they can setup a rendering pipeline and hand it over to the display server and immediately exit. As the rendering pipeline is kept alive until completion, the display server (or other consumer) can use the results in the future and present them to the user. The compute model is a little different. They have little to no buffer sharing between processes as their kernels tend to operate on a continuous stream, feeding the results back to the client application. These kernels operate for an indeterminate length of time, with many clients wishing that the kernel was always running for as long as they keep feeding in the data, i.e. acting like a DSP. Not all clients want this persistent "desktop" behaviour and would prefer that the contexts are cleaned up immediately upon closure. This ensures that when clients are run without hangchecking (e.g. for compute kernels of indeterminate runtime), any GPU hang or other unexpected workloads are terminated with the process and does not continue to hog resources. The default behaviour for new contexts is the legacy persistence mode, as some desktop applications are dependent upon the existing behaviour. New clients will have to opt in to immediate cleanup on context closure. If the hangchecking modparam is disabled, so is persistent context support -- all contexts will be terminated on closure. We expect this behaviour change to be welcomed by compute users, who have often been caught between a rock and a hard place. They disable hangchecking to avoid their kernels being "unfairly" declared hung, but have also experienced true hangs that the system was then unable to clean up. Naturally, this leads to bug reports.
