Plugging in an Apple dongle without the HDMI cable attached prints out an error message in the kernel logs when nothing is actually wrong. no downstream ports connected This is because the downstream port for the HDMI connector is not connected, so the Apple dongle reports that as a zero sink count device.

This function is basically a one-liner when you ignore the debug logging. Just inline the function and drop the log to simplify the code. Suggested-by:

As the INTF is fixed at the encoder creation time, we can move the check whether INTF supports tearchck to dpu_encoder_phys_cmd_init(). This function can return an error if INTF doesn't have required feature. Performing this check in dpu_encoder_phys_cmd_tearcheck_config() is less useful, as this function returns void. Signed-off-by:

The dpu_encoder_phys_cmd_te_rd_ptr_irq() function uses neither hw_intf nor hw_pp data, so we can drop the corresponding check. Reviewed-by:

Dmitry Baryshkov authored
The DPU_INTF_TE bit is set for all INTF blocks on DPU >= 5.0, however only INTF_1 and INTF_2 actually support tearing control (both are INTF_DSI). Rather than trying to limit the DPU_INTF_TE feature bit to those two INTF instances, check for the major && INTF type. Reviewed-by:

The DP CTS test for EDID last block checksum expects the checksum for the last block, invalid or not. Skip the validity check. For the most part (*), the EDIDs returned by drm_get_edid() will be valid anyway, and there's the CTS workaround to get the checksum for completely invalid EDIDs. See commit 7948fe12 ("drm/msm/dp: return correct edid checksum after corrupted edid checksum read"). This lets us remove one user of drm_edid_block_valid() with hopes the function can be removed altogether in the future. (*) drm_get_edid() ignores checksum errors on CTA extensions.

The function dp_link_parse_sink_count() is really just drm_dp_read_sink_count(). It debug prints out the bit for content protection (DP_SINK_CP_READY), but that is not useful beyond debug because 'link->dp_link.sink_count' is overwritten to only contain the sink_count in this same function. Just use drm_dp_read_sink_count() in the one place this function is called to simplify. Cc: Vinod Polimera <quic_vpolimer@quicinc.com> Cc: Kuogee Hsieh <quic_khsieh@quicinc.com> Signed-off-by:

We read the downstream port count and capability info but never use it anywhere. Remove 'ds_port_cnt' and 'ds_cap_info' and any associated code from this driver. Fold the check for 'dfp_present' into a call to drm_dp_is_branch() at the one place it is used to get rid of any member storage related to downstream ports.

This function duplicates the common function drm_dp_read_dpcd_caps().

Move the setting of dpu_enc::wide_bus_en to dpu_encoder_virt_atomic_enable() so that it mirrors how dpu_enc::dsc is being set. Since wide bus for DSI is related to DSC, having it mirror how DSC is set in DPU will also make it easier to accommodate for the possibility of DSC for DSI being set during runtime in the future.

In order to simplify IRQ declarations, shift IRQ indices by 1. This makes 0 the 'no IRQ' value. Thanks to this change, we do no longer have to explicitly set the 'no interrupt' fields in catalog structures. Reviewed-by:

Currently, dpu_plane_atomic_check() does not check whether the plane can process the image without exceeding the per chipset limits for MDP clock. This leads to underflow issues because the SSPP is not able to complete the processing for the data rate of the display. Fail the dpu_plane_atomic_check() if the SSPP cannot process the image without exceeding the MDP clock limits. changes in v2: - use crtc_state's adjusted_mode instead of mode Fixes: 25fdd593 ("drm/msm: Add SDM845 DPU support") Signed-off-by:

dsi_wait4video_done() API waits for the DSI video mode engine to become idle so that we can transmit the DCS commands in the beginning of BLLP. However, with the current sequence, the MDP timing engine is turned on after the panel's pre_enable() callback which can send out the DCS commands needed to power up the panel. During those cases, this API will always timeout and print out the error spam leading to long bootup times and log flooding. Fix this by checking if the DSI video engine was actually busy before waiting for it to become idle otherwise this is a redundant wait. changes in v2: - move the reg read below the video mode check - minor fixes in commit text Closes: https://gitlab.freedesktop.org/drm/msm/-/issues/34 Fixes: a689554b ("drm/msm: Initial add DSI connector support") Signed-off-by:

DP PHY re-initialization done using dp_ctrl_reinitialize_mainlink() will cause PLL unlocked initially and then PLL gets locked at the end of initialization. PLL_UNLOCKED interrupt will fire during this time if the interrupt mask is enabled. However currently DP driver link training implementation incorrectly re-initializes PHY unconditionally during link training as the PHY was already configured in dp_ctrl_enable_mainlink_clocks(). Fix this by re-initializing the PHY only if the previous link training failed.
