* drm/amd/display: Simplify brightness initializationCamille Cho2023-11-291-4/+0
| | | | | | | | | | | | | | | | | | | [Why] Remove the brightness cache in DC. It uses a single value to represent the brightness for both SDR and HDR mode. This leads to flash in HDR on/off. It also unconditionally programs brightness as in HDR mode. This may introduce garbage on SDR mode in miniLED panel. [How] Simplify the initialization flow by removing the DC cache and taking what panel has as default. Expand the mechanism for PWM to DPCD Aux to restore cached brightness value generally.

* drm/amd/display: switch DC over to the new DRM logging macrosHamza Mahfooz2023-09-261-0/+1
| | | | | | | | | | | | | | | | | | | | For multi-GPU systems it is difficult to tell which GPU a particular message is being printed for and that is undesirable because it complicates debugging efforts. Also, the new macros allow us to enable logging for particular parts of the codebase more selectively (since we no longer need to throw everything at DRM_DEBUG_KMS()). So, for the reasons outlined above we should switch to the new macros. We can accomplish this by using the existing DC_LOGGER code to pass around the relevant `struct drm_device` which will be fed to the new macros in logger_types.h. Also, we must get rid of all instances of the DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use the DC logger there and we can simply refer to the macros directly there instead.

* drm/amd/display: Add structs for Freesync Panel ReplayBhawanpreet Lakha2023-08-071-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | In some instances, the GPU is transmitting repeated frame to the sink without any updates or changes in the content. These repeat transmission are wasteful, resulting in power draw in different aspects of the system 1. DCN is fetching the frame of data from DF/UMC/DRAM. This memory traffic prevents power down of parts of this HW path. 2. GPU is transmitting pixel data to the display through the main link of the DisplayPort interface. This prevents power down of both the Source transmitter (TX) and the Sink receiver (RX)  The concepts of utilizing replay is similar to PSR, but there is a benefit of: Source and Sink remaining synchronized which allows for - lower latency when switching from replay to live frames - enable the possibility of more use cases - easy control of the sink's refresh rate during replay Due to Source and Sink remaining timing synchronized, Replay can be activated in more UI scenarios.

| | | | | | | | | | | | | | | | | | | | | | | [why] Link is a subcomponent in dc. DM should be aware of dc link structure as one of the abstracted objects maintained by dc. However it should have no idea of the existence of a link component in dc dedicated to maintain the states of dc link structure. As such we are moving link interfaces out of dc_link.h and directly added to dc.h. We are grandually fading out the explicit inclusion of dc_link header and eventually delete it. On dc side, since link is a subcomponent behind dc interfaces, it is not a good idea to implement dc interfaces in each individual subcomponent of link which is already a subcomponent of dc. So we are decoupling it by implementing a dc_link_exports in dc. This file will be a thin translation layer that breaks the dependency so link is able to make interface changes without breaking DM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why&How] Add a field to store the DCN IP offset for use with runtime offset calculation This offset is indexed using reg*_BASE_IDX for the corresponding group of registers. For example, address of DIG_BE_CNTL instance 0 is calculated like: dcn_reg_offsets[regDIG0_DIG_BE_CNTL_BASE_IDX] + regDIG0_DIG_BE_CNTL. {dcn,nbio}_reg_offsets are used only for the ASICs for which runtime initializaion of offsets are enabled through the modified SR* macros that contain an additional REG_STRUCT element in the macro definition. DCN3.5+ will fail dc_create() if {dcn,nbio}_reg_offsets are null. They are applicable starting with DCN32/321 and are not used for ASICs upstreamed before them. ASICs before DCN32/321 will not contain any computation that involves {dcn,nbio}_reg_offsets. For them, the address/offset computation is done during compile time. This is evident from the BASE_INNER definition for compile time vs run time initialization: Compile time init: #define BASE_INNER(seg) DCN_BASE__INST0_SEG ## seg Run time init: #define BASE_INNER(seg) ctx->dcn_reg_offsets[seg] BASE_INNER macro is local to each dcnxx_resource.c and hence different ASICs can have either runtime or compile time initialization of offsets. The computation of offset is done for registers all at once during driver load and hence it does not introduce any performance overhead during normal operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | [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.
