2023-09-26drm/amd/display: skip audio config for virtual signalAlex Hung
[WHY & HOW] IGT's kms_hdmi_inject (subtest inject_audio) triggers a warning message from dce_aud_az_configure. This can be fixed by checking Virtual signal that does not need to configure AZ audio since it does not have any.

2023-09-26drm/amd/display: Improve x86 and dmub ips handshakeDuncan Ma
[Why] There is a race condition between x86 and dmcub fw when attempting to exit IPS2. Scenarios including exiting IPS2 before IPS2 has been entered. This can cause unexpected hang when DMCUB attempt to exit while PMFW still tries to enter IPS2. [How] A new design has been introduced to remove race conditions and improve the handshake between x86 and DMCUB. An AON scratch register is borrowed from PMFW to determine whether DMCUB has committed to IPS entry or not. In the case when dmcub has committed IPS entry, x86 must poll until an exit event occurred either from DMCUB(IPS1) or PMFW(IPS2). x86 will wait upperbound of evaluation and IPS entry time to ensure IPS2 exit event has been sent to PMFW.

2023-09-20drm/amd/display: fix the ability to use lower resolution modes on eDPHamza Mahfooz
On eDP we can receive invalid modes from dm_update_crtc_state() for entirely new streams for which drm_mode_set_crtcinfo() shouldn't be called on. So, instead of calling drm_mode_set_crtcinfo() from within create_stream_for_sink() we can instead call it from amdgpu_dm_connector_mode_valid(). Since, we are guaranteed to only call drm_mode_set_crtcinfo() for valid modes from that function (invalid modes are rejected by that callback) and that is the only user of create_validate_stream_for_sink() that we need to call drm_mode_set_crtcinfo() for (as before commit cb841d27b876 ("drm/amd/display: Always pass connector_state to stream validation"), that is the only place where create_validate_stream_for_sink()'s dm_state was NULL).

[Why] Two issues fixed: 1. Currently, driver does not allow idle prior to PSR entry. Once PSR1+IPS is enabled, there is intermittent hang due to DCN access from IrqMgr during IPS2. 2. Driver is sending multiple commands to PMFW and dmcub to exit IPS even during IPS0. [How] 1. Set driver allow optimization prior to entering PSR mode with the condition for eDP display only. Unregister all interrupts before allowing driver idle and re-register interrupts when exiting from idle. This will prevent IrqMgr to access DCN during IPS2. 2. Block sending PMFW and dmcub exit low power state commands when driver is not in idle state.

This was never filled in and thus never truly used. Checking the EDID for content_type support is not required for sending the avi infoframe packet. v2: - rebase to amd-staging-drm-next Reviewed-by: Melissa Wen <mwen@igalia.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Joshua Ashton <joshua@froggi.es> Signed-off-by: Melissa Wen <mwen@igalia.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-09-20drm/amd/display: Hook up 'content type' property for HDMIJoshua Ashton
Implements the 'content type' property for HDMI connectors. Verified by checking the avi infoframe on a connected TV. This also simplifies a lot of the code in that area as well, there were a lot of temp variables doing very little and unnecessary logic that was quite confusing. It is not necessary to check for support in the EDID before sending a 'content type' value in the avi infoframe also. v2: - rebase to amd-staging-drm-next - mark CRTC state for reset if content_type differs Reviewed-by: Harry Wentland <harry.wentland@amd.com> (v1) Signed-off-by: Joshua Ashton <joshua@froggi.es> Co-developed-by: Melissa Wen <mwen@igalia.com> Signed-off-by: Melissa Wen <mwen@igalia.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
