[PATCH 1/6] drm/i915: Fix lock order reversal in GTT pwrite path.

Since the pagefault path determines that the lock order we use has to be mmap_sem - struct_mutex, we can't allow page faults to occur while the struct_mutex is held. To fix this in pwrite, we first try optimistically to see if we can copy from user without faulting. If it fails, fall back to

[PATCH 3/6] drm/i915: Fix lock order reversal in shmem pwrite path.

Like the GTT pwrite path fix, this uses an optimistic path and a fallback to get_user_pages. Note that this means we have to stop using vfs_write and roll it ourselves. Signed-off-by: Eric Anholt e...@anholt.net --- drivers/gpu/drm/i915/i915_gem.c | 225 +++

DRM lock ordering fix series

Here's hopefully the final attempt at the lock ordering fix for GEM. The problem was introduced in .29 with the GTT mapping support. We hashed out a few potential fixes on the mailing list and at OSTS. Peter's plan was to use get_user_pages, but it has significant CPU overhead (10% cost to text

We've wanted this for a few consumers that touch the pages directly (such as the following commit), which have been doing the refcounting outside of get/put pages. No idea if this is a valid point or not but whenever I see refcount that isn't a kref my internal, should this be a kref o-meter

Re: [PATCH 4/6] drm/i915: Fix lock order reversal in shmem pread path.

I've no idea when a fault is likely in the fast case, i.e. will it happen usually on the first page etc, because if it happens on the last page and you fallback and restart the whole copy, I would think that would be sub-optimal, granted it could get ugly quick, but this code has already hit
