Unfortunately, it appears our fix in: commit b5d29843 ("drm/atomic_helper: Allow DPMS On<->Off changes for unregistered connectors") Which attempted to work around the problems introduced by: commit 4d802739 ("drm/atomic_helper: Disallow new modesets on unregistered connectors") Is still not the right solution, as modesets can still be triggered outside of drm_atomic_set_crtc_for_connector(). So in order to fix this, while still being careful that we don't break modesets that a driver may perform before being registered with userspace, we replace connector->registered with a tristate member, connector->registration_state. This allows us to keep track of whether or not a connector is still initializing and hasn't been exposed to userspace, is currently registered and exposed to userspace, or has been legitimately removed from the system after having once been present. Using this info, we can prevent userspace from performing new modesets on unregistered connectors while still allowing the driver to perform modesets on unregistered connectors before the driver has finished being registered. Changes since v1: - Fix WARN_ON() in drm_connector_cleanup() that CI caught with this patchset in igt@drv_module_reload@basic-reload-inject and igt@drv_module_reload@basic-reload by checking if the connector is registered instead of unregistered, as calling drm_connector_cleanup() on a connector that hasn't been registered with userspace yet should stay valid. - Remove unregistered_connector_check(), and just go back to what we were doing before in commit 4d802739 ("drm/atomic_helper: Disallow new modesets on unregistered connectors") except replacing READ_ONCE(connector->registered) with drm_connector_is_unregistered(). This gets rid of the behavior of allowing DPMS On<->Off, but that should be fine as it's more consistent with the UAPI we had before - danvet - s/drm_connector_unregistered/drm_connector_is_unregistered/ - danvet - Update documentation, fix some typos.

The ENTER/EXIT_S_STATE actions queue the save/restore operation in GuC FW and then return, so waiting on the H2G is not enough to guarantee GuC is done. When all the processing is done, GuC writes 0 to scratch register 14, so we can poll on that. Note that GuC does not ensure that the value in the register is different from 0 while the action is in progress so we need to take care of that ourselves as well. v2: improve comment, return early on GuC error and improve error message (Michal) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by:Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Acked-by:

If BIOS configured a Y tiled FB we failed to set up the backing object tiling accordingly, leading to a lack of GT fence installed and a garbled console. The problem was bisected to commit 011f22eb ("drm/i915: Do NOT skip the first 4k of stolen memory for pre-allocated buffers v2") but it just revealed a pre-existing issue. Kudos to Ville who suspected a missing fence looking at the corruption on the screen.

has_drrs is a flag we can't read out.

LSPCON chips can generate YCBCR outputs, if asked nicely :). In order to generate YCBCR 4:2:0 outputs, a source must: - send YCBCR 4:4:4 signals to LSPCON - program color space as 4:2:0 in AVI infoframes Whereas for YCBCR 4:4:4 outputs, the source must: - send YCBCR 4:4:4 signals to LSPCON - program color space as 4:4:4 in AVI infoframes So for both 4:2:0 as well as 4:4:4 outputs, we are driving the pipe for YCBCR 4:4:4 output, but AVI infoframe's color space information indicates LSPCON FW to start scaling down from YCBCR 4:4:4 and generate YCBCR 4:2:0 output. As the scaling is done by LSPCON device, we need not to reserve a scaler for 4:2:0 outputs. V2: rebase V3: Addressed review comments from Ville - add enum crtc_output_format instead of bool ycbcr420 - use crtc_output_format=4:4:4 for modeset of LSPCON 4:2:0 output cases in this way we will have YCBCR 4:4:4 framework ready (except the ABI part) V4: Added r-b from Maarten (for v3) Addressed review comments from Ville: - Do not add a non-atomic state variable to determine lspcon output. Instead add bool in CRTC state to indicate lspcon based scaling. V5: Addressed review comments from Ville: - Change the state bool name from external scaling to something more relavent. - Keep the info and adjusted_mode structures const. - use crtc_state instead of pipe_config. - Push all the config change into lspcon_ycbcr420_config function.
