The analog link detection code path had already performed the
DAC load detection by the time the EDID read is attempted.
So there is no need to repeat the DAC load detection,
we can know that no display is connected if no EDID is read.

GFX ring resets work differently on pre-GFX10 hardware since
there is no MQD managed by the scheduler.
For ring reset, you need issue the reset via CP_VMID_RESET
via KIQ or MMIO and submit the following to the gfx ring to
complete the reset:
1. EOP packet with EXEC bit set
2. WAIT_REG_MEM to wait for the fence
3. Clear CP_VMID_RESET to 0
4. EVENT_WRITE ENABLE_LEGACY_PIPELINE
5. EOP packet with EXEC bit set
6. WAIT_REG_MEM to wait for the fence
Once those commands have completed the reset should
be complete and the ring can accept new packets.

[Why]
Reenable new split implementation, previously partially reverted due
to issues with ODM on high-bandwidth displays 4k144Hz, resulting
in a corrupted gray screen.
Minimal flows require two separate commits, with extra intermediate
commit to enable seamless transitions, each followed by a swap. Since
new design requires commit to be run in execute and swap in cleanup
stage, an attempt was made to reorder them from CSCS (Commit-Swap-Commit-Swap)
to CCSS (Commit-Commit-Swap-Swap). Not only is this not viable, but
was implemented incorrectly as CCS, one swap missing.
[How]
* Change UPDATE_V3_FLOW_NEW_CONTEXT_MINIMAL_NEW/CURRENT to execute
and cleanup one commit, then run UPDATE_V3_FLOW_NEW_CONTEXT_SEAMLESS,
which closely matches old implementation where minimal flows fall back
to seamless.
* Fix uninitialized variable error.

[WHY]
When performing 4:1 downscaling with subsampled formats,
the SPL remainder distribution logic (+1) overrides the
upper layer’s aligned width, resulting in odd segment
widths and causing hang.
The upper layer alignment ensures the width is sufficient
and even, so SPL should not modify it further.
[HOW]
In dc_spl.c within calculate_mpc_slice_in_timing_active,
add an extra condition: Skip the remainder distribution
(+1) when use_recout_width_aligned is true.This change
respects the upper layer’s alignment decision, prevents
odd widths, and is a minimal, safe fix.
