[WHY] There is a bug in HW that causes P-State to hang when DPG is enabled in certain conditions. [HOW] The solution is to force MIN_TTU_VBLANK register to maximum value whenever DPG has been enabled. Make stream do a full update on test pattern change, so that the TTUs get updated. When DPG is enabled, update the ttu_regs.min_ttu_vblank field of each pipe in the stream's topology to the maximum value (0xffffff). v2: squash in build fix for when DCN is not defined (Alex) Signed-off-by:

[Why] Some display endpoints may be programmably mapped to compatible link encoders. The assignment of link encoders to links has to be dynamic to accommodate the increased flexibility in comparison to conventional display endpoints. [How] - Add link encoder assignment tracking variables. - Execute link encoder assignment algorithm before enabling link and release link encoders from links once they are disabled. Signed-off-by:

[WHY] Some systems can enable LTTPR through bits in BIOS, while other systems can be configured at boot to enable LTTPR. Some configs enable Non-Transparent mode, while others enable Transparent mode. Signed-off-by:

Wesley Chalmers authored
[WHY] There are three possible modes for LTTPR: - Non-LTTPR mode, where AUX timeout is 400 us and no per-hop link training is done - LTTPR Transparent mode, where AUX timeout is 3200 us and no per-hop link training is done - LTTPR Non-Transparent mode, where AUX timeout is 3200 us and per-hop link training is done [HOW] Use an enum instead of a bool to track LTTPR state; modify comparisons accordingly.

[why] This was a regression introduced by commit: drm/amd/display: Skip modeset for front porch change Due to the change how timing parameters were set, scaled modes would cause a black screen on some eDP panels. Would probably apply to other displays (i.e. even non-eDP) that only have scaled modes, but such case is not that usual for external displays. [how] Pick up crtc frame dimensions when programming the timing unless it's FreeSync video mode.

Amdgpu driver uses 4-byte data type as DQM fence memory, and transmits GPU address of fence memory to microcode through query status PM4 message. However, query status PM4 message definition and microcode processing are all processed according to 8 bytes. Fence memory only allocates 4 bytes of memory, but microcode does write 8 bytes of memory, so there is a memory corruption. Changes since v1: * Change dqm->fence_addr as a u64 pointer to fix this issue, also fix up query_status and amdkfd_fence_wait_timeout function uses 64 bit fence value to make them consistent.

v1: Add generic amdgpu_reset_control to handle different types of resets. It may be added at device, hive or ip level. Each reset control has a list of handlers associated with it to handle different types of reset. Reset control is responsible for choosing the right handler given a particular reset context. Handler objects may implement a set of functions on how to handle a particular type of reset. prepare_env = Prepare environment/software context (not used currently). prepare_hwcontext = Prepare hardware context for the reset. perform_reset = Perform the type of reset. restore_hwcontext = Restore the hw context after reset. restore_env = Restore the environment after reset (not used currently).
