As we can clearly see in a downstream kernel [1], flushing the slave INTF is skipped /only if/ the PPSPLIT topology is active. However, when DPU was originally submitted to mainline PPSPLIT was no longer part of it (seems to have been ripped out before submission), but this clause was incorrectly ported from the original SDE driver. Given that there is no support for PPSPLIT (currently), flushing the slave INTF should /never/ be skipped (as the `if (ppsplit && !master) goto skip;` clause downstream never becomes true).

When dual-DSI (bonded DSI) was added in commit ed9976a0 ("drm/msm/dsi: adjust dsi timing for dual dsi mode") some DBG() prints were not updated, leading to print the original mode->clock rather than the adjusted (typically the mode clock divided by two, though more recently also adjusted for DSC compression) msm_host->pixel_clk_rate which is passed to clk_set_rate() just below. Fix that by printing the actual pixel_clk_rate that is being set. Fixes: ed9976a0 ("drm/msm/dsi: adjust dsi timing for dual dsi mode") Signed-off-by:

Instead of having two functions, msm_dsi_manager_bridge_init() and msm_dsi_manager_ext_bridge_init(), merge them into msm_dsi_manager_connector_init(), moving drm_bridge_attach() to be called from the bridge's attach callback (as most other bridges do). Signed-off-by:

Currently the MSM DSI driver looks for the next bridge during msm_dsi_modeset_init(). If the bridge is not registered at that point, this might result in -EPROBE_DEFER, which can be problematic that late during the device probe process. Move next bridge acquisition to the dsi_bind state so that probe deferral is returned as early as possible. Signed-off-by:

The gen_header.py script is failing for older versions of python3 such as python 3.5. Two issues observed with python 3.5 are ... 1. Python 3 versions prior to 3.6 do not support the f-string format. 2. Early python 3 versions do not support the 'required' argument for the argparse add_subparsers(). Fix both of the above so that older versions of python 3 still work. Fixes: 8f7abf0b86fe ("drm/msm: generate headers on the fly") Signed-off-by:Jon Hunter <jonathanh@nvidia.com> Reviewed-by:

The dp_audio read and write operations uses members in struct dp_catalog for passing arguments and return values. This adds unnecessary complexity to the implementation, as it turns out after detangling the logic that no state is actually held in these variables.

Logging u32 pixel formats using %4.4s format string with a pointer to the u32 is somewhat questionable, as well as dependent on byte order. There's a kernel extension format specifier %p4cc to format 4cc codes. Use it across the board in msm for pixel format logging. This should also fix the reported build warning: include/drm/drm_print.h:536:35: warning: '%4.4s' directive argument is null [-Wformat-overflow=] Reported-by:

Before the introduction of the wait_hpd_asserted() callback in commit 841d742f ("drm/dp: Add wait_hpd_asserted() callback to struct drm_dp_aux") the API between panel drivers and DP AUX bus drivers was that it was up to the AUX bus driver to wait for HPD in the transfer() function. Now wait_hpd_asserted() has been added. The two panel drivers that are DP AUX endpoints use it. See commit 2327b13d ("drm/panel-edp: Take advantage of wait_hpd_asserted() in struct drm_dp_aux") and commit 3b5765df ("drm/panel: atna33xc20: Take advantage of wait_hpd_asserted() in struct drm_dp_aux"). We've implemented wait_hpd_asserted() in the MSM DP driver as of commit e2969ee3 ("drm/msm/dp: move of_dp_aux_populate_bus() to eDP probe()"). There is no longer any reason for long wait in the AUX transfer() function. Remove it. NOTE: the wait_hpd_asserted() is listed as "optional". That means it's optional for the DP AUX bus to implement. In the case of the MSM DP driver we implement it so we can assume it will be called. ALSO NOTE: the wait wasn't actually _hurting_ anything and wasn't even causing long timeouts, but it's still nice to get rid of unneeded code. Specificaly it's not truly needed because to handle other DP drivers that can't power on as quickly (specifically parade-ps8640) we already avoid DP AUX transfers for eDP panels that aren't powered on. See commit 8df1ddb5 ("drm/dp: Don't attempt AUX transfers when eDP panels are not powered"). Signed-off-by:

The DP wait_hpd_asserted() callback is passed a timeout which indicates how long we should wait for HPD. This timeout was being ignored in the MSM DP implementation and instead a hardcoded 500 ms timeout was used. Fix it to use the proper timeout. As part of this we move the hardcoded 500 ms number into the AUX transfer function, which isn't given a timeout. The wait in the AUX transfer function will be removed in a future commit.

As documented in the description of the transfer() function of "struct drm_dp_aux", the transfer() function can be called at any time regardless of the state of the DP port. Specifically if the kernel has the DP AUX character device enabled and userspace accesses "/dev/drm_dp_auxN" directly then the AUX transfer function will be called regardless of whether a DP device is connected. For eDP panels we have a special rule where we wait (with a 5 second timeout) for HPD to go high. This rule was important before all panels drivers were converted to call wait_hpd_asserted() and actually can be removed in a future commit. For external DP devices we never checked for HPD. That means that trying to access the DP AUX character device (AKA `hexdump -C /dev/drm_dp_auxN`) would very, very slowly timeout. Specifically on my system: $ time hexdump -C /dev/drm_dp_aux0 hexdump: /dev/drm_dp_aux0: Connection timed out real 0m8.200s We want access to the drm_dp_auxN character device to fail faster than 8 seconds when no DP cable is plugged in. Let's add a test to make transfers fail right away if a device isn't plugged in. Rather than testing the HPD line directly, we have the dp_display module tell us when AUX transfers should be enabled so we can handle cases where HPD is signaled out of band like with Type C.
