46d9ebf9fd drm/tests: Do not use drm_fb_blit() in format-helper tests 
[ Upstream commit 5a4856e0e3 ]

Export additional helpers from the format-helper library and open-code
drm_fb_blit() in tests. Prepares for the removal of drm_fb_blit(). Only
sysfb drivers use drm_fb_blit(). The function will soon be removed from
format helpers and be refactored within sysfb helpers.

d0d7c93b4b drm/tests: shmem: Fix memleak 
[ Upstream commit 48ccf21fa8 ]

The drm_gem_shmem_test_get_pages_sgt() gets a scatter-gather table using
the drm_gem_shmem_get_sg_table() function and rightfully calls
sg_free_table() on it. However, it's also supposed to kfree() the
returned sg_table, but doesn't.

This leads to a memory leak, reported by kmemleak. Fix it by adding a
kunit action to kfree the sgt when the test ends.

f951d643bc drm/tests: helpers: Create kunit helper to destroy a drm_display_mode 
[ Upstream commit 13c1d5f3a7 ]

A number of test suites call functions that expect the returned
drm_display_mode to be destroyed eventually.

However, none of the tests called drm_mode_destroy, which results in a
memory leak.

Since drm_mode_destroy takes two pointers as argument, we can't use a
kunit wrapper. Let's just create a helper every test suite can use.

02a12760d7 drm/tests: hdmi: Fix recursive locking 
[ Upstream commit 5d14c08a47 ]

The find_preferred_mode() functions takes the mode_config mutex, but due
to the order most tests have, is called with the crtc_ww_class_mutex
taken. This raises a warning for a circular dependency when running the
tests with lockdep.

Reorder the tests to call find_preferred_mode before the acquire context
has been created to avoid the issue.

The light_up_connector helper function in the HDMI infrastructure unit
tests uses drm_atomic_set_crtc_for_connector(), but fails when it

This function can return EDEADLK though if the sequence needs to be

properly.

Let's handle EDEADLK and restart the sequence in our tests as well.

f378b77227 drm/connector: hdmi: Add Infoframes generation 
Infoframes in KMS is usually handled by a bunch of low-level helpers
that require quite some boilerplate for drivers. This leads to
discrepancies with how drivers generate them, and which are actually
sent.

Now that we have everything needed to generate them in the HDMI
connector state, we can generate them in our common logic so that
drivers can simply reuse what we precomputed.

e5030a74f9 drm/connector: hdmi: Add custom hook to filter TMDS character rate 
Most of the HDMI controllers have an upper TMDS character rate limit
they can't exceed. On "embedded"-grade display controllers, it will
typically be lower than what high-grade monitors can provide these days,
so drivers will filter the TMDS character rate based on the controller
capabilities.

To make that easier to handle for drivers, let's provide an optional
hook to be implemented by drivers so they can tell the HDMI controller
helpers if a given TMDS character rate is reachable for them or not.

This will then be useful to figure out the best format and bpc count for
a given mode.

Most HDMI drivers have some code to calculate the TMDS character rate,
usually to adjust an internal clock to match what the mode requires.

Since the TMDS character rates mostly depends on the resolution, whether
we need to repeat pixels or not, the bpc count and the format, we can
now derive it from the HDMI connector state that stores all those infos
and remove the duplication from drivers.
