Make the assertion failure message readable if gem_read or gem_write

Insted of calling drmIoctl() directly, call igt_ioctl() instead. In the
normal scenario this is function pointer that calls drmIoctl() (so no
penalty), but allows us to divert ioctls into our own routines for
nefarious purposes. One such purpose will be to control interrupt
generation into the ioctl, to be able to detect when we successfully
interrupt the ioctl and when we no longer need more interrupts.

Check that the system operates normally before and after the suspend (as
well as across the suspend). The goal is to isolate the breakage to the

For many tests, the relevant aperture is not the ppGTT but the internal

This patch adds dma-buf mmap synchronization ioctls that can be used by tests
for cache coherency management e.g. when CPU and GPU domains are being accessed
through dma-buf at the same time.

This patch adds test_correct_cpu_write, which maps the texture buffer through a
prime fd and then writes directly to it using the CPU. It stresses the driver
to guarantee cache synchronization among the different domains.
This test also adds test_forked_cpu_write, which creates the GEM bo in one
process and pass the prime handle of the it to another process, which in turn
uses the handle only to map and write. Roughly speaking this test simulates
Chrome OS architecture, where the Web content ("unpriviledged process") maps
and CPU-draws a buffer, which was previously allocated in the GPU process
("priviledged process").
This requires kernel modifications (Daniel Thompson's "drm: prime: Honour
O_RDWR during prime-handle-to-fd") and therefore prime_handle_to_fd_for_mmap is
added to fail in case these lack. Also, upcoming tests (e.g. next patch) are
going to use it as well, so make it public and available in the lib.
v2: adds prime_handle_to_fd_with_mmap for skipping test in older kernels and
test for invalid flags.

This patch moves userptr definitions and helpers implementation that were
locally in gem_userptr_benchmark and gem_userptr_blits to the library, so other
tests can make use of them as well. There's no functional changes.
v2: added __ function to differentiate when errors want to be handled back in
the caller; bring gem_userptr_sync back to gem_userptr_blits; added gtkdoc.
v8: remove local_i915_gem_userptr from gem_concurrent_all.c to use the global
helpers instead.

In context tests, we may create thousands of contexts, the noise from

do the requirement test (to detect if contexts are meant to be supported
or plain broken) only on the error path.

No functional changes.
While I'm here, let's also rename gem_uses_aliasing_ppgtt (since it's
being used to indicate if we are using ANY kind of ppgtt) and introduce
gem_uses_full_ppgtt to drop some unnecessary code from tests that were
previously calling getparam directly instead of using ioctl wrapper.
v2: drop gem_uses_full_48b_ppgtt since it's no longer used anywhere,

Some potential callers want to inject a hang into a particular context,
some want to trigger an actual ban and others may or may not want to
capture the associated error state. Expand the hang injection interface
to suit all.
v2: Disable the new kernel API, but push to provide a missing piece of
infrastucture to unbreak compilation.

If we move the igt_require() into the hang injector, this makes simple
test cases even more convenient. More complex test cases can always do
their own precursory check before settting up the test.
However, this does embed the assumption that the first context we are
called from is safe (i.e no i915.enable_hangcheck/i915.reset
interferrence).
v2: A couple of environment variables to skip hang testing or to force
hang injection even if the GPU cannot be reset.

This patch adds the testcases for verifying the new extended
gem_create ioctl. By means of this extended ioctl, memory
placement of the GEM object can be specified, i.e. either
shmem or stolen memory.
These testcases include functional tests and interface tests for
testing the gem_create ioctl call for stolen memory placement
v2: Testing pread/pwrite functionality for stolen backed objects,
added local struct for extended gem_create and gem_get_aperture,
until headers catch up (Chris)
v3: Removed get_aperture related functions, extended gem_pread
to compare speeds for user pages with and without page faults,
unexposed local_gem_create struct, changed gem_create_stolen
usage (Chris)
v4: Splitting patch to remove changes from gem_pread/gem_pwrite
to another patch (Ankit)
v5: Fixed Rebase conflicts (Ankit)
Added IGT_TEST_DESCRIPTION (Thomas Wood)
v6: Added __gem_create_stolen for user to handle error, updated
gem_create_stolen to align with gem_create function, corrected
fill_purge test (out of bound access), added testcase to validate
allocating of more than 32 bit sized buffers (Tvrtko)

gem_set_caching() tries to be clever and detect when the ioctl isn't
supported (thereby skipping the test). However, it forget that we may be
acting on active objects and be subject to the usual EAGAIN/EINTR
errors. We can use the drmIoctl() to wrap the raw ioctl() in order to
get the automatic restart on the interrupted syscall.

Rename the current gem_mmap__{cpu,gtt,wc}() functions into
__gem_mmap__{cpu,gtt,wc}(), and add back wrappers with the original name
that assert that the pointer is valid. Most callers will expect a valid
pointer and shouldn't have to bother with failures.
To avoid changing anything (yet), sed 's/gem_mmap__/__gem_mmap__/g'
over the entire codebase.

We frequently check for device capabilities, for which we can safely
assume that there is but one on a system and so cache the first query
value and return it for all future queries. The benefit is to reduce
dmesg debug spam which helps when either bringing up a test or trying to
track down why a test fails.

When synchronising to rendering, we only want to wait for it to complete
and avoid the cache-domain side-effects of SET_DOMAIN if possible. This
has the advantage of speeding up a few tests (and thereby making the
actual test more explicit in terms of kernel operations). Of course some
tests may be reliant on the side-effects...

Just a few basic tests to make sure fb modifiers can be used and
behave sanely when mixed with the old set_tiling API.
v2:
* Review feedback from Daniel Vetter:
1. Move cap detection into the subtest so skipping works.
2. Added some gtkdoc comments.
3. Two more test cases.
4. Removed unused parts for now.
v3:
* Removed two tests which do not make sense any more after the
fb modifier rewrite.
v4:
* Moved gtkdoc comments into .c file.
* Moved all initialization into fixtures.
* Rebased for fb modifier changes.
v5:
* Added bad modifier subtest.

After setting up the copy operations, add a hanging batch. This should
mean that we complete the copy and the compare then races against the
GEM reset. Hopefully, this will catch driver bugs where the target
object is no longer accessible after the hang.
Note: hang injection is disabled until the required kernel interface is
completed. But there are useful additional tests here...
