2017-05-04drm/mm: Split up long running selftests with cond_resched()Chris Wilson1-0/+28
Scatter a few cond_resched() in between phases of the drm_mm selftests to try and prevent us incurring the wrath of the NMI watchdog.

2017-02-03drm: Improve drm_mm search (and fix topdown allocation) with rbtreesChris Wilson1-32/+26
The drm_mm range manager claimed to support top-down insertion, but it was neither searching for the top-most hole that could fit the allocation request nor fitting the request to the hole correctly. In order to search the range efficiently, we create a secondary index for the holes using either their size or their address. This index allows us to find the smallest hole or the hole at the bottom or top of the range efficiently, whilst keeping the hole stack to rapidly service evictions. v2: Search for holes both high and low. Rename flags to mode. v3: Discover rb_entry_safe() and use it! v4: Kerneldoc for enum drm_mm_insert_mode.

2017-01-11drm: Fix error handling in drm_mm eviction kselftestChris Wilson1-3/+9
drivers/gpu/drm/selftests/test-drm_mm.c:1277 evict_everything() warn: calling list_del() inside list_for_each The list_del() inside the error handling in the eviction loop is overkill. We have to undo the eviction scan to return the drm_mm back to a recoverable state, so have to iterate over the full list, but we only want to report the error once and once we have an error we can return early.

2016-12-28drm: Apply tight eviction scanning to color_adjustChris Wilson1-2/+18
Using mm->color_adjust makes the eviction scanner much tricker since we don't know the actual neighbours of the target hole until after it is created (after scanning is complete). To work out whether we need to evict the neighbours because they impact upon the hole, we have to then check the hole afterwards - requiring an extra step in the user of the eviction scanner when they apply color_adjust. v2: Massage kerneldoc.

2016-12-27drm: Add some kselftests for the DRM range manager (struct drm_mm)Chris Wilson4-0/+216
First we introduce a smattering of infrastructure for writing selftests. The idea is that we have a test module that exercises a particular portion of the exported API, and that module provides a set of tests that can either be run as an ensemble via kselftest or individually via an igt harness (in this case igt/drm_mm). To accommodate selecting individual tests, we export a boolean parameter to control selection of each test - that is hidden inside a bunch of reusable boilerplate macros to keep writing the tests simple. v2: Choose a random random_seed unless one is specified by the user. v3: More parameters to control max_iterations and max_prime of the tests.
