<title>drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport</title>

<id>0ad4b4a2f6357c45fbe444ead1a929a0b4017d03</id>
<content type='text'>
[Why]
Potential out of bounds access in dml2_calculate_rq_and_dlg_params()
because the value of out_lowest_state_idx used as an index for FCLKChangeSupport
array can be greater than 1.

[How]
Currently dml2 core specifies identical values for all FCLKChangeSupport
elements. Always use index 0 in the condition to avoid out of bounds access.

<title>drm/amd/display: Account for cursor prefetch BW in DML1 mode support</title>

<content type='text'>
[Description]
We need to ensure to take into account cursor prefetch BW in
mode support or we may pass ModeQuery but fail an actual flip
which will cause a hang. Flip may fail because the cursor_pre_bw
is populated during mode programming (and mode programming is
never called prior to ModeQuery).

<title>drm/amd/display: Attempt to avoid empty TUs when endpoint is DPIA</title>
<updated>2024-06-19T18:17:25+00:00</updated>

<name>Michael Strauss</name>

<id>c03d770c0b014a3007a5874bf6b3c3e64d32aaac</id>
<content type='text'>
[WHY]
Empty SST TUs are illegal to transmit over a USB4 DP tunnel.
Current policy is to configure stream encoder to pack 2 pixels per pclk
even when ODM combine is not in use, allowing seamless dynamic ODM
reconfiguration. However, in extreme edge cases where average pixel
count per TU is less than 2, this can lead to unexpected empty TU
generation during compliance testing. For example, VIC 1 with a 1xHBR3
link configuration will average 1.98 pix/TU.

[HOW]
Calculate average pixel count per TU, and block 2 pixels per clock if
endpoint is a DPIA tunnel and pixel clock is low enough that we will
never require 2:1 ODM combine.

Now that all previously-supported architectures select
ARCH_HAS_KERNEL_FPU_SUPPORT, this code can depend on that symbol instead
of the existing list of architectures.  It can also take advantage of the
common kernel-mode FPU API and method of adjusting CFLAGS.

The compiler flags enable altivec, but that is not required; hard-float is
sufficient for the code to build and function.

Drop altivec from the compiler flags and adjust the enable/disable code to
only enable FPU use.

Pull drm updates from Dave Airlie:
 "This is the main pull request for the drm subsystems for 6.10.

  In drivers the main thing is a new driver for ARM Mali firmware based
  GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and
  scattered changes to everything else.

  In the core a bunch of headers and Kconfig was refactored, along with
  the addition of a new panic handler which is meant to provide a user
  friendly message when a panic happens and graphical display is
  enabled.

  New drivers:
   - panthor: ARM Mali/Immortalis CSF-based GPU driver

   - add a CONFIG_DRM_WERROR option

   - Kconfig cleanups
   - DT sound bindings
   - Add SIZE_HINTS property for cursor planes
   - Add struct drm_edid_product_id and helpers.
   - Use drm device based logging in more drm functions.

   - use drm_edid driver conversions
