Someone on IRC once asked an innocent enough sounding question: Why with xf86-video-modesetting is es2gears limited at 120fps. So I broke out the perfetto tracing mesa MR and took a look. It turns out the problem was drm_atomic_helper_dirtyfb(), which would end up waiting for vblank.. es2gears would rapidly push two frames to Xorg, which would blit them to screen and in idle hook (I assume) call the DIRTYFB ioctl. Which in turn would do an atomic update to flush the dirty rects, which would stall until the next vblank. And then the whole process would repeat. But this is a bit silly, we only need dirtyfb for command mode DSI panels. So track in plane state whether dirtyfb is required, and track in the fb how many attached planes require dirtyfb so that we can skip it when not required. (Note, mdp4 does not actually have cmd mode support.) Signed-off-by:

QCM2290 MDSS includes a Qualcomm DSI controller v2.4.1. Since this controller version is not SoC specific, and already assigned to sc7180 for auto configuration, we rely on DSI block specific compatible string "qcom,dsi-ctrl-6g-qcm2290", and use the device's data to point to the right dsi config handler.

Config autodetect based on DSI controller version is quite limited since several qcom SoCs can integrate a DSI controller with the same version, but with different config (io_offset, supplies, etc). This change allows to specify dsi config via device data pointer. config autodetect is still used in case data pointer is NULL. Signed-off-by:

Other processes don't need to know about faults that they are isolated from by virtue of address space isolation. They are only interested in whether some of their state might have been corrupted.

Currently DP driver will allocate panel bridge for eDP panels. This supports only the following topology: - eDP encoder ⇒ eDP panel (wrapped using panel-bridge) Simplify this code to just check if there is any next bridge in the chain (be it a panel bridge or regular bridge). Rename panel_bridge field to next_bridge accordingly. This allows one to use e.g. one of the following display topologies: - eDP encoder ⇒ ptn3460 ⇒ fixed LVDS panel - eDP encoder ⇒ ptn3460 ⇒ LVDS connector with EDID lines for panel autodetect - eDP encoder ⇒ ptn3460 ⇒ THC63LVD1024 ⇒ DPI panel. - eDP encoder ⇒ LT8912 ⇒ DSI panel Signed-off-by:

In commit 8a3b4c17 ("drm/msm/dp: employ bridge mechanism for display enable and disable") the DP driver received a drm_bridge instance, which is always attached to the encoder as a root bridge. However it conflicts with the panel_bridge support for eDP panels. The panel bridge attaches to the encoder before the "dp" bridge (DP driver's drm_bridge instance created in msm_dp_bridge_init()) has a chance to do so. Change panel bridge attachment to come after the "dp" bridge attachment (and to use it as a previous bridge).

In function dpu_encoder_phys_cmd_wait_for_commit_done we are always checking if the relative CTL is started by waiting for an interrupt to fire: it is fine to do that, but then sometimes we call this function while the CTL is up and has never been put down, but that interrupt gets raised only when the CTL gets a state change from 0 to 1 (disabled to enabled), so we're going to wait for something that will never happen on its own. Solving this while avoiding to restart the CTL is actually possible and can be done by just checking if it is already up and running when the wait_for_commit_done function is called: in this case, so, if the CTL was already running, we can say that the commit is done if the command transmission is complete (in other terms, if the interface has been flushed).

DPU driver contains code to parse clock items from device tree into special data struct and then enable/disable/set rate for the clocks using that data struct. However the DPU driver itself uses only parsing and enabling/disabling part (the rate setting is used by DP driver). Move this implementation to the DP driver (which actually uses rate setting) and replace hand-coded enable/disable/get loops in the DPU with the respective clk_bulk operations. Put operation is removed completely because, it is handled using devres instead. DP implementation is unchanged for now.

dpu_kms_debugfs_init() is invoked for each minor being registered. Most of the files created are unrelated to the minor, so there's no reason to present them per minor. The exception to this is the DisplayPort code, which ends up invoking dp_debug_get() for each minor, each time associate the allocated object with dp->debug. As such dp_debug will create debugfs files in both the PRIMARY and the RENDER minor's debugfs directory, but only the last reference will be remembered. The only use of this reference today is in the cleanup path in dp_display_deinit_sub_modules() and the dp_debug_private object does outlive the debugfs entries in either case, so there doesn't seem to be any adverse effects of this, but per the code the current behavior is unexpected, so change it to only create debugfs files for the PRIMARY minor.

The SC8180x platform supports the newly added DPU_INTF_WIDEBUS flag and the Windows-on-Snapdragon bootloader leaves the widebus bit set, so this is flagged appropriately to ensure widebus is disabled - for now.
