2019-02-28lib: Incrementally mlock()Chris Wilson
As we already have the previous portion of the mmap mlocked, we only need to mlock() the fresh portion for testing available memory. v2: Fixup the uint64_t pointer arithmetric and only use a single mmap to avoid subsequent mlock fail (for reasons unknown, but bet on mm/).

2018-06-13igt/evictions: Avoid getting killed by the reaper in mlockMichał Winiarski
We're little bit too enthusiastic in our initial attempt to lock all available memory. Let's use the mlock probe from lib rather than trying to lock everything that sysinfo.freeram has to offer. Note that we're only tweaking the initial step - it's still possible that we're going to get killed later on. v2: Just increment lock instead of modifying addr passed to mlock Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ewelina Musial <ewelina.musial@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Ewelina Musial <ewelina.musial@intel.com>
2017-03-09igt/evictions: Isolate the mlock check in a separate processChris Wilson
The initial mlock() is to check we can assigned all of memory to ourselves -- without the kernel killing us. Move that check to an isolated process so that we sacrifice the child. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-02-04igt/gem_userptr_blits: Limit amount of mlocked surfacesChris Wilson
When testing surface eviction we don't need that many surfaces as we mlock surplus memory. Reducing the number of surfaces speeds up the test and prevents a couple of integer overflow bugs.

2015-08-21lib: add a single include headerThomas Wood
Add a header that includes all the headers for the library. This allows reorganisation of the library without affecting programs using it and also simplifies the headers that need to be included to use the library. Signed-off-by: Thomas Wood <thomas.wood@intel.com>

2015-03-30igt/gem_evict_everything: Simplify mlocked_evictionsChris Wilson
igt_fork/igt_waitchildren already perform the magic required to raise errors based on the exit error code of the child, so take advantage of that and kill the overlycomplicated message passing! Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-03-29igt/gem_evict_everything: Use mlock to reduce available memoryChris Wilson
The idea here is to check what happens when a large process requests memory from us - we create and utilize a bunch of surfaces then have to relinquish some but continue using the whole working set (so as to force reloads). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-07-21igt/gem_userptr_blits: New tests, old issuesChris Wilson
Introduce a new test to keep that we clean up on process exit (if the userptr is busy or it has been gtt mmapped). This revealed a few bugs in the existing tests so clean those up. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-05igt/gem_evict_everything: Compute number of surfaces to saturate the apertureChris Wilson
The goal is to only fill the aperture, not all of memory, so fine-tune the computed number of surfaces, hopefully avoiding an integer overflow in the process. References: https://bugs.freedesktop.org/show_bug.cgi?id=79573 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-02-26evictions: Limit the number of minor eviction surfaces to fit in RAMChris Wilson
We allocate more surfaces than used in a single pass in order to stress the eviction code between batches. The intent here is not to exercise swapping, and we fail to check that there is enough swap+memory to hold all our surfaces. So limit the number of surfaces we allocate to fit into RAM, and then require that the number of surfaces we need for testing is less than the number of surfaces we can allocate.
