drm_gem_shmem_test_purge [1] and drm_gem_shmem_test_get_pages_sgt [2]
intermittently fail on ppc64le and s390x CI systems with a DMA address
overflow:

  DMA addr 0x0000000100307000+4096 overflow (mask ffffffff, bus limit 0)
  WARNING: kernel/dma/direct.h:114 dma_direct_map_sg+0x778/0x920

  drm_gem_shmem_test_purge: ASSERTION FAILED at
    drivers/gpu/drm/tests/drm_gem_shmem_test.c:330
    Expected sgt is not error, but is: -5

The call chain leading to the failure is:

  drm_gem_shmem_test_purge() / drm_gem_shmem_test_get_pages_sgt()
    drm_gem_shmem_get_pages_sgt()
      drm_gem_shmem_get_pages_sgt_locked() [drm_gem_shmem_helper.c]
        dma_map_sgtable()                  [mapping.c]
          __dma_map_sg_attrs()
            dma_direct_map_sg()            [direct.c]
              dma_direct_map_phys()        [kernel/dma/direct.h]
                dma_capable()              Checks addr against DMA mask
                  -&gt; FAILS: addr &gt; 0xFFFFFFFF

The root cause is that KUnit devices are initialized with a 32-bit DMA
mask (DMA_BIT_MASK(32)) in lib/kunit/device.c. On ppc64le and s390x
systems with physical memory above 4GB, page allocations can land at
addresses that exceed this mask. When drm_gem_shmem_get_pages_sgt()
attempts to DMA-map these pages via dma_map_sgtable(), the DMA layer
rejects the mapping because the physical address overflows the 32-bit
mask.

The failure is intermittent because pages may or may not be allocated
above 4GB on any given run depend on memory pressure.

Fix by setting a 64-bit DMA mask on the device before calling
drm_gem_shmem_get_pages_sgt() for all tests, following the same pattern
already used in drm_gem_shmem_test_obj_create_private().

<title>drm/bridge: Remove legacy bridge callback support</title>

All bridge drivers have been converted to the atomic variants of the
enable, disable, pre_enable, and post_disable callbacks.

Remove the deprecated legacy hooks from drm_bridge_funcs, the
drm_bridge_is_atomic() helper that was only needed to distinguish
between atomic and non-atomic bridges, and the legacy bridge test
cases.

Since all bridges are now atomic, unconditionally initialize the
private object state at attach time.

drm_for_each_bridge_in_chain_scoped() was added in commit e46efc6a7d28
("drm/bridge: add drm_for_each_bridge_in_chain_scoped()") to provide a
safer alternative to drm_for_each_bridge_in_chain().

Following commits converted all users to the _scoped variant.

Finally commit 2f08387a444c ("drm/bridge: remove
drm_for_each_bridge_in_chain()") removed the old
drm_for_each_bridge_in_chain() macro.

It's time to rename drm_for_each_bridge_in_chain_scoped() back to the
original name.

<title>drm/drm_exec: avoid indirect goto</title>

<id>4e28aa8f7ee26d67a4addee6e3980f1cbf861b49</id>
<content type='text'>
The drm_exec component uses a variable with scope limited to the for() and
an indirect goto to allow instantiating multiple macros in the same
function.

This unfortunately doesn't work well with certain compilers when the
indirect goto can't be lowered to a direct jump.

Switch the indirect goto to a direct goto, the drawback is that we now
can't use the dma_exec_until_all_locked() macro in the same function
multiple times.

The is currently only one user of this and only as a hacky workaround
which is about to be removed.

So document that the __label__ statement should be used when the macro is
used multiple times and fix the tests and the only use case where that is
necessary.

Pull drm updates from Dave Airlie:
 "Highlights:
   - xe: add initial CRI platform support
   - amdgpu: initial HDMI 2.1 FRL support
   - rust: add some new type concepts for device lifetimes
   - scheduler: moves to a fair algorithm and lots of cleanups

  But it's mostly the usual mountain of changes across the board.

  core:
   - add docbook for DRM_IOCTL_SYNCOBJ_EVENTFD
   - change signature of drm_connector_attach_hdr_output_metadata_property
   - dedup counter and timestamp retrieval in vblank code
   - parse AMD VSDB v3 in CTA extension blocks
   - add P230, Y7, XYYY2101010, T430, XVUY210101010 formats
   - don't call drop master on file close if not master
   - use drm_printf_indent in atomic / bridge
   - fix 32b format descriptions
   - docs: fix toctree
   - hdmi: add common TMDS character rates
   - fix drm_syncobj_find_fence leak

  rust:
   - introduce Higher-Ranked lifetime types
   - replace drvdata with scoped registration data
   - add GPUVM immediate mode abstraction for rust GPU drivers
   - introduce DeviceContext type state for drm::Device

<title>drm/tests: Move test EDID data to separate .c file</title>

<id>2693c9572eaf28ea82b772b84f758e20072539f7</id>
<content type='text'>
Having the test EDID arrays defined in the .h directly will duplicate
them across every user of the EDID arrays. This works fine as long as
there's only one user, but may produce build warnings/errors when there
are multiple users and not all of them use all definitions.

Move the array definitions to a new .c file, and mark the declarations
in the header as "extern" to avoid the linker throwing a fit, and give
them an explicit size (either 128 or 256, depending on EDID) to avoid
the compiler inferring that they must be size 1.

The common atomic_get_output_bus_fmts helper for HDMI bridge connectors,
called drm_atomic_helper_bridge_get_hdmi_output_bus_fmts, should return
an array of output bus formats depending on the supported formats of the
connector, and the current output BPC.

Add a test to exercise some of this helper.
