2022-01-11drm/amdgpu: not return error on the init_apu_flagsPrike Liang1-4/+2

2022-01-11drm/amdkfd: Use prange->update_list head for remove_listFelix Kuehling2-6/+2
The remove_list head was only used for keeping track of existing ranges that are to be removed from the svms->list. The update_list was used for new or existing ranges that need updated attributes. These two cases are mutually exclusive (i.e. the same range will never be on both lists). Therefore we can use the update_list head to track the remove_list and save another 16 bytes in the svm_range struct.

2022-01-11drm/amdkfd: Use prange->list head for insert_listFelix Kuehling2-11/+8
There are seven list_heads in struct svm_range: list, update_list, remove_list, insert_list, svm_bo_list, deferred_list, child_list. This patch and the next one remove two of them that are redundant. The insert_list head was only used for new ranges that are not on the svms->list yet. So we can use that list head for keeping track of new ranges before they get added, and use list_move_tail to move them to the svms->list when ready.

2022-01-11drm/amdkfd: make SPDX License expression more soundLukas Bulwahn1-1/+1
Commit b5f57384805a ("drm/amdkfd: Add sysfs bitfields and enums to uAPI") adds include/uapi/linux/kfd_sysfs.h with the "GPL-2.0 OR MIT WITH Linux-syscall-note" SPDX-License expression. The command ./scripts/spdxcheck.py warns: include/uapi/linux/kfd_sysfs.h: 1:48 Exception not valid for license MIT: Linux-syscall-note For a uapi header, the file under GPLv2 License must be combined with the Linux-syscall-note, but combining the MIT License with the Linux-syscall-note makes no sense, as the note provides an exception for GPL-licensed code, not for permissively licensed code. So, reorganize the SPDX expression to only combine the note with the GPL License condition. This makes spdxcheck happy again.

2022-01-07drm/amd/display: Don't reinitialize DMCUB on s0ix resumeNicholas Kazlauskas1-3/+27
[Why] PSP will suspend and resume DMCUB. Driver should just wait for DMCUB to finish the auto load before continuining instead of placing it into reset, wiping its firmware state and reinitializing. If we don't let DMCUB fully finish initializing for S0ix then some state will be lost and screen corruption can occur due to incorrect address translation. [How] Use dmub_srv callbacks to determine in DMCUB is running and wait for auto-load to complete before continuining. In S0ix DMCUB will be running and DAL fw so initialize will skip. In S3 DMCUB will not be running and we will do a full hardware init. In S3 DMCUB will be running but will not be DAL fw so we will also do a full hardware init.

We need to unify the meaning of these hardware indices across different system configuration. [how] 1. Temporarly move the hardcoded mapping to dc_resource level, which should have full awareness of asic specific configuration and add a TODO comment to move the mapping to DMUB. 2. populate dio_output_idx/phy_idx for all configuration, define usb4_enabled bit instead of dio_output_type as an external enum.

[why] There will be a series of re-arch changes in Link Resource Management.

Therefore a link resource sharing logic is required to determine which link should use certain link resource. This commit is the first one in this series that starts by defining a link resource struct, this struct will be available to all interfaces that need to perform link programming sequence. In later commits, we will granduately decouple link resource objects out of dc link. So instead of access a link resource from dc link. Current link's resource can be accessible through pipe_ctx->link_res during commit, or by calling dc_link_get_cur_link_res function with current link passed in after commit.
