[Why] During DP tunnel creation, CM preallocates BW and reduces estimated BW of other DPIA. CM release preallocation only when allocation is complete. Display mode validation logic validates timings based on bw available per host router. In multi display setup, this causes bw allocation failure when allocation greater than estimated bw. [How] Do zero alloc to make the CM to release preallocation and update estimated BW correctly for all DPIAs per host router. Reviewed-by:

[Why] DSC debugfs, such as dp_dsc_clock_en_read, use aconnector->dc_link to find pipe_ctx for display. Displays connected to MST hub share the same dc_link. DSC instance is from pipe_ctx. This causes incorrect DSC instance for display connected to MST hub. [How] Add aconnector->sink check to find pipe_ctx. CC: stable@vger.kernel.org Reviewed-by:

[Description] - Block FPO if the max stretch refresh rate is low enough to cause a flicker by storing the maximum safe refresh decrease from nominal in stream. - Brought over various Freesync Luminance functions to dc. Use these new functions to block fpo if we will flicker. - Generalized increase/reduce dependent functions to reduce code clutter and allow for easier use. - Added a debug option to enable the feature. Disabled by default. Co-authored-by:

[Why] Upon disconnecting a UHBR SST display, the disconnection and the SetTimings to disable the display can occur such that link_set_dpms_off occurs after the disconnection has already processed (link->type is dc_connection_none). Thus, the AUX related operations should be skipped when clearing the payload allocation table. Reviewed-by:

New request from KMD/VBIOS in order to support new UMA carveout model. This fixes a null dereference from accessing Ctx->dc_bios->integrated_info while it was NULL. DAL parses through the BIOS and extracts the necessary integrated_info but was missing a case for the new BIOS version 2.3. Reviewed-by:

Add a new KFD alloc memory flag and store as bo alloc flag AMDGPU_GEM_CREATE_VRAM_CONTIGUOUS. When pin this bo to export for RDMA peerdirect access, this will set TTM_PL_FLAG_CONTIFUOUS flag, and ask VRAM buddy allocator to get contiguous VRAM. Signed-off-by:

-Wframe-larger-than=2048 is a part of both CFLAGS and CFLAGS_REMOVE for dml2_core_dcn4_calcs.o, which means that it ultimately gets removed altogether for 64-bit targets, as 2048 is the default FRAME_WARN value for 64-bit platforms, resulting in no -Wframe-larger-than coverage for this file. Remove -Wframe-larger-than from CFLAGS_REMOVE_dml2_core_dcn4_calcs.o and move to $(frame_warn_flag) for CFLAGS_dml2_core_dcn4_calcs.o, as that accounts for the fact that -Wframe-larger-than may need to be larger than 2048 in certain situations, such as when the sanitizers are enabled.
