[Intel-gfx] [PATCH v4 i-g-t 00/15] Fixes for i915_hangman and gem_exec_capture

[Intel-gfx] [PATCH v4 i-g-t 00/15] Fixes for i915_hangman and gem_exec_capture

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Fix a bunch of issues with i915_hangman and gem_exec_capture with the
ultimate aim of making them pass on GuC enabled platforms.

v2: Fixes to the store code. Add engine properties management.
v3: Fix for platforms without pre-emption.
v4: Simplify anti-ban code, support >32bit store offsets and fix
memory mapping on discrete platforms.

[Intel-gfx] [PATCH v4 i-g-t 02/15] lib/hang: Fix igt_require_hang_ring to work with all engines

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The above function was checking for valid rings via the old interface.
The new scheme is to check for engines on contexts as there are now
more engines than could be supported.

[Intel-gfx] [PATCH v4 i-g-t 03/15] tests/i915/i915_hangman: Update capture test to use engine structure

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The capture test was still using old style ring_id and ring_name
(derived from the engine structure at the higher level). Update it to
just take the engine structure directly.

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Although the hangman test was ensuring that *some* reset functionality
was enabled, it did not differentiate what kind. The infrastructure
required to choose between per engine reset or full GT reset was
recently added. So update this test to use it as well.

[Intel-gfx] [PATCH v4 i-g-t 05/15] tests/i915/i915_hangman: Add uevent test & fix detector

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Some of the IGT framework relies on receving a uevent when a hang
occurs. So add a test that this actually works.

While testing this, noticed that hangs could sometimes be missed
because the uevent was (presumably) still in flight by the time the
handler was de-registered. So add an extra delay during cleanup to
give the uevent chance to arrive.

[Intel-gfx] [PATCH v4 i-g-t 06/15] tests/i915/i915_hangman: Use the correct context in hangcheck_unterminated

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The hangman framework sets up a context that is valid for all engines
and has things like banning disabled. The 'unterminated' test then
ignores it and uses the default context. Fix that.

[Intel-gfx] [PATCH v4 i-g-t 07/15] lib/store: Refactor common store code into helper function

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

A lot of tests use almost identical code for creating a batch buffer
which does a single write to memory and another is about to be added.
Instead, move the most generic version into a common helper function.
Unfortunately, the other instances are all subtly different enough to
make it not so trivial to try to use the helper. It could be done but
it is unclear if it is worth the effort at this point. This patch
proves the concept, if people like it enough then it can be extended.

v2: Fix up object address vs store offset confusion (with help from
Zbigniew K).
v3: Cope with >32bit store_offset (review feedback from Matthew Brost).

[igt-dev] [PATCH v4 i-g-t 07/15] lib/store: Refactor common store code into helper function

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

A lot of tests use almost identical code for creating a batch buffer
which does a single write to memory and another is about to be added.
Instead, move the most generic version into a common helper function.
Unfortunately, the other instances are all subtly different enough to
make it not so trivial to try to use the helper. It could be done but
it is unclear if it is worth the effort at this point. This patch
proves the concept, if people like it enough then it can be extended.

v2: Fix up object address vs store offset confusion (with help from
Zbigniew K).
v3: Cope with >32bit store_offset (review feedback from Matthew Brost).

[Intel-gfx] [PATCH v4 i-g-t 08/15] tests/i915/i915_hangman: Add alive-ness test after error capture

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Added a an extra step to the i915_hangman tests to check that the
system is still alive after the hang and recovery. This submits a
simple batch to each engine which does a write to memory and checks
that the write occurred.

v2: Use _device_coherent instead of _wc for mapping memory to support
discrete boards.

[Intel-gfx] [PATCH v4 i-g-t 09/15] tests/i915/i915_hangman: Remove reliance on context persistance

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The hang test was relying on context persitence for no particular
reason. That is, it would set a bunch of background spinners running
then immediately destroy the active contexts but expect the spinners
to keep spinning. With the current implementation of context
persistence in i915, that means that super high priority pings are
sent to each engine at the start of the test. Depending upon the
timing and platform, one of those unexpected pings could cause test
failures.

There is no need to require context persitence in this test. So change
to managing the contexts cleanly and only destroying them when they
are no longer in use.

As opposed to only on the non-target engines. This means that there is
some other workload present for the scheduler to switch between and so

[Intel-gfx] [PATCH v4 i-g-t 11/15] tests/i915/i915_hangman: Don't let background contexts cause a ban

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The global context used by all the subtests for causing hangs is
marked as unbannable. However, some of the subtests set background
spinners running on all engines using a freshly created context. If
there is a test failure for any reason, all of those spinners can be
killed off as hanging contexts. On systems with lots of engines, that
can result in the test being banned from creating any new contexts.

So make the spinner contexts unbannable as well. That way if one
subtest fails it won't necessarily bring down all subsequent subtests.

v2: Simplify anti-banning code (review feedback from Matthew Brost).

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Some platforms have very long timeouts configured for some engines.
Some have them disabled completely. That makes for a very slow (or
broken) hangman test. So explicitly configure the engines to have
reasonable settings first.

[Intel-gfx] [PATCH v4 i-g-t 15/15] tests/i915/gem_exec_capture: Restore engines

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The test was updated some engine properties but not restoring them
afterwards. That would leave the system in a non-default state which
could potentially affect subsequent tests. Fix it by using the new
save/restore engine properties helper functions.

  **FAILURE**

  Serious unknown changes coming with IGTPW_6555_full absolutely need to be
  verified manually.
  
  If you think the reported changes have nothing to do with the changes
