[Intel-gfx] [PATCH 0/6] Fix the debugfs splat from mock selftests (v3)

[Intel-gfx] [PATCH 0/6] Fix the debugfs splat from mock selftests (v3)

[Jason Ekstrand]

This patch series fixes a miscellaneous collection of bugs that all add up
to all our mock selftests throwing dmesg warnings in CI.  As can be seen
from "drm/i915: Use a table for i915_init/exit", it's especially fun since
those warnings don't always show up in the selftests but can show up in
other random IGTs depending on test execution order.

Jason Ekstrand (6):
  drm/i915: Call i915_globals_exit() after i915_pmu_exit()
  drm/i915: Call i915_globals_exit() if pci_register_device() fails
  drm/i915: Use a table for i915_init/exit (v2)
  drm/ttm: Force re-init if ttm_global_init() fails
  drm/ttm: Initialize debugfs from ttm_global_init()
  drm/i915: Make the kmem slab for i915_buddy_block a global

We should tear down in the opposite order we set up.

[Intel-gfx] [PATCH 2/6] drm/i915: Call i915_globals_exit() if pci_register_device() fails

[Jason Ekstrand]

In the unlikely event that pci_register_device() fails, we were tearing
down our PMU setup but not globals.  This leaves a bunch of memory slabs
lying around.

[Intel-gfx] [PATCH 3/6] drm/i915: Use a table for i915_init/exit (v2)

[Jason Ekstrand]

If the driver was not fully loaded, we may still have globals lying
around.  If we don't tear those down in i915_exit(), we'll leak a bunch
of memory slabs.  This can happen two ways: use_kms = false and if we've
run mock selftests.  In either case, we have an early exit from
i915_init which happens after i915_globals_init() and we need to clean
up those globals.

The mock selftests case is especially sticky.  The load isn't entirely
a no-op.  We actually do quite a bit inside those selftests including
allocating a bunch of mock objects and running tests on them.  Once all
those tests are complete, we exit early from i915_init().  Perviously,
i915_init() would return a non-zero error code on failure and a zero
error code on success.  In the success case, we would get to i915_exit()
and check i915_pci_driver.driver.owner to detect if i915_init exited early
and do nothing.  In the failure case, we would fail i915_init() but
there would be no opportunity to clean up globals.

The most annoying part is that you don't actually notice the failure as
part of the self-tests since leaking a bit of memory, while bad, doesn't
result in anything observable from userspace.  Instead, the next time we
load the driver (usually for next IGT test), i915_globals_init() gets
invoked again, we go to allocate a bunch of new memory slabs, those
implicitly create debugfs entries, and debugfs warns that we're trying
to create directories and files that already exist.  Since this all
happens as part of the next driver load, it shows up in the dmesg-warn
of whatever IGT test ran after the mock selftests.

While the obvious thing to do here might be to call i915_globals_exit()
after selftests, that's not actually safe.  The dma-buf selftests call
i915_gem_prime_export which creates a file.  We call dma_buf_put() on
the resulting dmabuf which calls fput() on the file.  However, fput()
isn't immediate and gets flushed right before syscall returns.  This
means that all the fput()s from the selftests don't happen until right
before the module load syscall used to fire off the selftests returns
which is after i915_init().  If we call i915_globals_exit() in
i915_init() after selftests, we end up freeing slabs out from under
objects which won't get released until fput() is flushed at the end of
the module load syscall.

The solution here is to let i915_init() return success early and detect
the early success in i915_exit() and only tear down globals and nothing
else.  This way the module loads successfully, regardless of the success
or failure of the tests.  Because we've not enumerated any PCI devices,
no device nodes are created and it's entirely useless from userspace.
The only thing the module does at that point is hold on to a bit of
memory until we unload it and i915_exit() is called.  Importantly, this
means that everything from our selftests has the ability to properly
flush out between i915_init() and i915_exit() because there is at least
one syscall boundary in between.

In order to handle all the delicate init/exit cases, we convert the
whole thing to a table of init/exit pairs and track the init status in
the new init_progress global.  This allows us to ensure that i915_exit()
always tears down exactly the things that i915_init() successfully
initialized.  We also allow early-exit of i915_init() without failure by
an init function returning > 0.  This is useful for nomodeset, and
selftests.  For the mock selftests, we convert them to always return 1
so we get the desired behavior of the driver always succeeding to load
the driver and then properly tearing down the partially loaded driver.

v2 (Tvrtko Ursulin):
 - Guard init_funcs[i].exit with GEM_BUG_ON(i >= ARRAY_SIZE(init_funcs))
v2 (Daniel Vetter):
 - Update the docstring for i915.mock_selftests

[Intel-gfx] [PATCH 4/6] drm/ttm: Force re-init if ttm_global_init() fails

[Jason Ekstrand]

If we have a failure, decrement the reference count so that the next
call to ttm_global_init() will actually do something instead of assume
everything is all set up.

[Intel-gfx] [PATCH 5/6] drm/ttm: Initialize debugfs from ttm_global_init()

[Jason Ekstrand]

We create a bunch of debugfs entries as a side-effect of
ttm_global_init() and then never clean them up.  This isn't usually a
problem because we free the whole debugfs directory on module unload.
However, if the global reference count ever goes to zero and then
ttm_global_init() is called again, we'll re-create those debugfs entries
and debugfs will complain in dmesg that we're creating entries that
already exist.  This patch fixes this problem by changing the lifetime
of the whole TTM debugfs directory to match that of the TTM global
state.

I've pushed this to drm-misc-fixes since I think this entire slab debugfs
story started with 5.15-rc1, so good to get it sorted there.

[Intel-gfx] [PATCH 6/6] drm/i915: Make the kmem slab for i915_buddy_block a global

[Jason Ekstrand]

There's no reason that I can tell why this should be per-i915_buddy_mm
and doing so causes KMEM_CACHE to throw dmesg warnings because it tries
to create a debugfs entry with the name i915_buddy_block multiple times.
We could handle this by carefully giving each slab its own name but that
brings its own pain because then we have to store that string somewhere
and manage the lifetimes of the different slabs.  The most likely
outcome would be a global atomic which we increment to get a new name or
something like that.

The much easier solution is to use the i915_globals system like we do
for every other slab in i915.  This ensures that we have exactly one of
them for each i915 driver load and it gets neatly created on module load
and destroyed on module unload.  Using the globals system also means
that its now tied into the shrink handler so we can properly respond to
low-memory situations.

It was intentionally ripped it out with the idea that we would be moving 
the buddy stuff into ttm, and so part of that was trying to get rid of 
the some of the i915 specifics, like this globals thing.

I just sent out a patch to put i915_globals on a diet, so maybe we can
hold this patch here a bit when there's other reasons for why this is
special?

Or at least no make this use the i915_globals stuff and instead just link
up the init/exit function calls directly into Jason's new table, so that
we don't have a merge conflict here?

I'm happy to deal with merge conflicts however they land.
