No need for a separate flag now that DCN3.1 is not in bring up. Fold into DRM_AMD_DC_DCN like previous DCN IPs. Reviewed-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amd/display: Add DCN3.1 DMCUB

2021-06-04T20:39:18Z

DMCU-B (Display Micro-Controller Unit B) is a display microcontroller used for shared display functionality with BIOS and for advanced power saving display features. Extends the command header to include new DCN3.1 functionality. Adds new interfaces to DC dmub interface as well for z-state support.

drm/amd/display: Support for DMUB AUX

2021-03-02T19:05:41Z

[WHY] To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes. [HOW] 1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd with DCN and sends reply back in an outbox1 message triggering an outbox1 interrupt to driver. 2) In existing driver implementation, AUX commands are processed synchronously by configuring DCN reg. But in DMUB AUX, driver sends an inbox1 message and waits for a conditional variable (CV) which will be signaled by outbox1 ISR. 3) As the driver holds dal and dc locks while waiting for CV, the outbox1 ISR is registered with noMutexWait set to true, which allows ISR to run and signal CV. This sets a constraint on ISR to not modify variables such as dc, dmub, etc. 4) Created dmub_outbox.c with dmub_enable_outbox_notification() to enable outbox1 mailbox. 5) New mailbox address ranges allocated for outbox1 of size DMUB_RB_SIZE. Created dmub functions for Outbox1: dmub_dcn20_setup_out_mailbox(), dmub_dcn20_get_outbox1_wptr() and dmub_dcn20_set_outbox1_rptr(). 6) Added functions dc_stat_get_dmub_notification() and dmub_srv_stat_get_notification() to retrieve Outbox1 message. 7) Currently, DMUB doesn't opens DDC in AUX mode before issuing AUX transaction. A workaround is added in dce_aux_transfer_dmub_raw() to open in DDC in AUX mode for every AUX transaction. 8) Added dc debug option enable_dmub_aux_for_legacy_ddc enable/disable DMUB AUX. This debug option is checked dce_aux_transfer_with_retries() to select the method to process AUX transactions.
