Similar to the handling of amdgpu_sa_bo_next_hole in commit 6a15f3ff ("drm/amdgpu: Initialize fences array entries in amdgpu_sa_bo_next_hole"), we thought a patch might be needed here as well. The entries were only initialized once in radeon_sa_bo_new. If a fence wasn't signalled yet in the first radeon_sa_bo_next_hole call, but then got signalled before a later radeon_sa_bo_next_hole call, it could destroy the fence but leave its pointer in the array, resulting in use-after-free in radeon_sa_bo_new.

Extend KFD device topology to surface peer-to-peer links among GPU devices connected over PCIe or xGMI. Enabling HSA_AMD_P2P is REQUIRED to surface peer-to-peer links. Prior to this KFD did not expose to user mode any P2P links or indirect links that go over two or more direct hops. Old versions of the Thunk used to make up their own P2P and indirect links without the information about peer-accessibility and chipset support available to the kernel mode driver. In this patch we expose P2P links in a new sysfs directory to provide more reliable P2P link information to user mode. Old versions of the Thunk will continue to work as before and ignore the new directory. This avoids conflicts between P2P links exposed by KFD and P2P links created by the Thunk itself. New versions of the Thunk will use only the P2P links provided in the new p2p_links directory, if it exists, or fall back to the old code path on older KFDs that don't expose p2p_links.

[Why] In cases where there are multiple eDP instances, DMUB needs to know which instance the command is for. Today, the field for specifying the panel_inst exists in both dmub_cmd_update_dirty_rect_data and dmub_cmd_update_cursor_info_data. For cursor updates, we already specify the panel_inst, but that's not the case for dirty_rect updates. Today, a value of '0' is used (due to initial memsetting of the cmd struct to 0) [how] In dc_dmub_update_dirty_rect(), Call dc_get_edp_link_panel_inst() to get the panel_inst, and fill it in the DMUB cmd struct. v2: Update commit message for clarity.

[Why] PSR-SU Rate Control - or PSR-SU-RC - enables PSR-SU panels to work with variable refresh rate to allow for more power savings. Lowering the refresh rate can increase PSR residency by expanding the eDP main link shut down duration. It can also lower panel power consumption. There is a complication with PSR, since the eDP main link can be shut down. Therefore, the timing controller (TCON) on the eDP sink nees to be able to scan out its remote buffer independent of the main link. To allow the eDP source to specify the sink's refresh rate while the link is off, vendor-specific DPCD registers are used. This allows the eDP source to then "Rate Control" the panel during PSR active. [How] Add DC support to communicate with PSR-SU-RC supported eDP sinks. The sink will need to know the desired VTotal during PSR active. This change only adds support to DC, support in amdgpu_dm is still pending to enable this fully. Signed-off-by:

[why] 1. When HPD deassertion is pulled in the middle of enabe stream link training, we will abort current training and turn off PHY. This causes current link settings to be zeroed this causes later stream enablement sequence to fail as we prefer to carry on enablement process despite of link training failure for SST. 2. When HPD is toggled after detection before before the enable stream sequence as a result. There could be a race condition where we could end up enable stream based on the previous link even though the link is updated after the HPD toggle. This causes an issue where our link bandwidth is no longer enough to accommodate the timing therefore causes us to oversubscribe MST payload time slots. As discussed we decided to add basic sanity check to make sure that our code can handle the oversubscription failure silently without system hang. [how] 1. Keep PHY powered on when HPD is deasserted during enable stream and wait for the detection sequence to power it off later. 2. Do not allocate payload if the required timeslot for current timing is greater than 64 timeslots. Reviewed-by:
