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).

2023-09-20drm/i915: Implement transcoder LRR for TGL+Ville Syrjälä
Implement low refresh rate (LRR) where we change the vblank length by hand as requested, but otherwise keep the timing generator running in non-VRR mode (ie. fixed refresh rate). The panel itself must support VRR for this to work, and only TGL+ has the double buffred TRANS_VTOTAL.VTOTAL that we need to make the switch properly. The double buffer latching happens at the start of transcoders undelayed vblank. The other thing that we change is TRANS_VBLANK.VBLANK_END but the hardware entirely ignores that in DP mode. But I decided to keep writing it anyway just to avoid more special cases in readout/state check. v2: Document that TRANS_VBLANK.VBLANK_END is ignored by the hardware v3: Reconcile with VRR fastset Adjust update_lrr flag behaviour Make sure timings stay within VRR range v4: Fix up update_m_n vs. update_lrr rebase fail (Manasi) Drop DOUBLE_BUFFER_VACTIVE define as it's not needed (Manasi) TODO: Hook LRR into the automatic DRRS downclocking stuff?

In that case when we toggle VRR on/off we would step outside the VRR range when toggling VRR on/off. Let's just make sure that never happens by not using VRR in such cases.

Make the seamless_m_n flag more like the update_pipe fastset flag, ie. the flag will only be set if we need to do the seamless M/N update, and in all other cases the flag is cleared. Also rename the flag to update_m_n to make it more clear it's similar to update_pipe. I believe special casing seamless_m_n like this makes sense as it also affects eg. vblank evasion. We can potentially avoid some vblank evasion tricks, simplify some checks, and hopefully will help with the VRR vs. M/N mess.

2023-09-20drm/i915: Enable VRR later during fastsetsVille Syrjälä
In order to reconcile seamless M/N updates with VRR we'll need to defer the fastset VRR enable to happen after the seamless M/N update (which happens during the vblank evade critical section). So just push the VRR enable to be the last thing during the update. This will also affect the vblank evasion as the transcoder will now still be running with the old VRR state during the vblank evasion. So just grab the timings always from the old crtc state during any non-modeset commit, and also grab the current state of VRR from the active timings (as we disable VRR before vblank evasion during fastsets). This also fixes vblank evasion for seamless M/N updates as we now properly account for the fact that the M/N update happens after vblank evasion.

When external bridges are attached with DRM_BRIDGE_ATTACH_NO_CONNECTOR, the panel bridge may also get the same flag, but in the .attach() callback for the panel bridge a device link is added only when this flag is not present; To make things worse, the .detach() callback tries to delete the device link unconditionally and without checking if it was created in the first place, crashing the kernel with a NULL pointer kernel panic upon calling panel_bridge_detach(). Fix that by moving the device_link_add() call before checking if the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is present.

During jpeg init, CPU writes to frame buffer which can be cached by HDP, occasionally causing invalid header to be sent to MMSCH. Perform HDP flush after writing to frame buffer before continuing with jpeg init sequence.

2023-09-20drm/amd: Drop special case for yellow carp without discoveryMario Limonciello
`amdgpu_gmc_get_vbios_allocations` has a special case for how to bring up yellow carp when amdgpu discovery is turned off. As this ASIC ships with discovery turned on, it's generally dead code and worse it causes `adev->mman.keep_stolen_vga_memory` to not be initialized for yellow carp. Remove it.

2023-09-20drm: Update file owner during useTvrtko Ursulin
With the typical model where the display server opens the file descriptor and then hands it over to the client(*), we were showing stale data in debugfs. Fix it by updating the drm_file->pid on ioctl access from a different process. The field is also made RCU protected to allow for lockless readers. Update side is protected with dev->filelist_mutex. Before: $ cat /sys/kernel/debug/dri/0/clients command pid dev master a uid magic Xorg 2344 0 y y 0 0 Xorg 2344 0 n y 0 2 Xorg 2344 0 n y 0 3 Xorg 2344 0 n y 0 4 After: $ cat /sys/kernel/debug/dri/0/clients command tgid dev master a uid magic Xorg 830 0 y y 0 0 xfce4-session 880 0 n y 0 1 xfwm4 943 0 n y 0 2 neverball 1095 0 n y 0 3 *) More detailed and historically accurate description of various handover implementation kindly provided by Emil Velikov: """ The traditional model, the server was the orchestrator managing the primary device node. From the fd, to the master status and authentication. But looking at the fd alone, this has varied across the years. IIRC in the DRI1 days, Xorg (libdrm really) would have a list of open fd(s) and reuse those whenever needed, DRI2 the client was responsible for open() themselves and with DRI3 the fd was passed to the client. Around the inception of DRI3 and systemd-logind, the latter became another possible orchestrator. Whereby Xorg and Wayland compositors could ask it for the fd. For various reasons (hysterical and genuine ones) Xorg has a fallback path going the open(), whereas Wayland compositors are moving to solely relying on logind... some never had fallback even. Over the past few years, more projects have emerged which provide functionality similar (be that on API level, Dbus, or otherwise) to systemd-logind.
