As the page-table trees within the GTT are naturally aligned to power-of-two boundaries, by inserting an object that crosses a power-of-two (and the power-of-two intervals) we can quickly check the code for errors in switching between levels in the tree. Signed-off-by:

i915_gem_gtt_insert should allocate from the available free space in the GTT, evicting as necessary to create space. Signed-off-by:

i915_gem_gtt_reserve should put the node exactly as requested in the GTT, evicting as required. Signed-off-by:

Very simple tests to just ask eviction to find some free space in a full GTT and one with some available space. Signed-off-by:

Ensure that we minimally exercise the aliasing_ppgtt, even on a full-ppgtt, by allocating one and similarly creating a context to use it. Signed-off-by:

Chris Wilson authored
In order to force testing of the aliasing ppgtt, extract its initialisation function. v2: Also extract the cleanup function for symmetry. Signed-off-by:

Check we can create and execution within a context. v2: Write one set of dwords through each context/engine to exercise more contexts within the same time period. Signed-off-by:

It is possible whilst allocating the page-directory tree for a ppgtt bind that the shrinker may run and reap unused parts of the tree. If the shrinker happens to remove a chunk of the tree that the allocate_va_range has already processed, we may then try to insert into the dangling tree. This test uses the fault-injection framework to force the shrinker to be invoked before we allocate new pages, i.e. new chunks of the PD tree.

Directly test allocating the va range and clearing it, this bypasses the use of i915_vma_bind() and inserting the pages to focus on testing of the pagetables. Signed-off-by:

Allocate objects with varying number of pages (which should hopefully consist of a mixture of contiguous page chunks and so coalesced sg lists) and check that the sg walkers in insert_pages cope. v2: Check both small <-> large Signed-off-by:

Though we have good coverage of our dmabuf interface through the mock tests, we also want to check the heavy module unload paths of the live i915 driver. Signed-off-by:

Chris Wilson authored
Check that we can create both dmabuf and objects from dmabuf. v2: Cleanups, correct include, fix unpin on dead path and prevent explosion on dmabuf init failure Signed-off-by:

Add a late selftest that walks over all forcewake registers (those below 0x40000) and uses the mmio debug register to check to see if any are unclaimed. This is possible if we fail to wake the appropriate powerwells for the register. Signed-off-by:

In addition to just testing the fw table we load, during the initial mock testing we can test that all tables are valid (so the testing is not limited to just the platforms that load that particular table). Signed-off-by:

Now that the kselftest infrastructure exists, put it to use and add to it the existing consistency checks on the fw register lookup tables. v2: s/tabke/table/ Signed-off-by:

The phys object is a rarely used device (only very old machines require a chunk of physically contiguous pages for a few hardware interactions). As such, it is not exercised by CI and to combat that we want to add a test that exercises the phys object on all platforms. v2: Always set err on error paths and not rely on inheriting the err.

Simple starting point for adding seltests for i915_gem_request, first mock a device (with engines and contexts) that allows us to construct and execute a request, along with waiting for the request to complete. Signed-off-by:

We would like to be able to exercise huge allocations even on memory constrained devices. To do this we create an object that allocates only a few pages and remaps them across its whole range - each page is reused multiple times. We can therefore pretend we are rendering into a much larger object. Signed-off-by:
