These casts need to happen before the shift. The only time it would matter would be if "rev.core" is >= 128. In that case the sign bit would be extended and we do not want that. Fixes: afab9d91 ("drm/msm/adreno: Expose speedbin to userspace") Signed-off-by:

refcount_t complains about 0->1 transitions, which isn't *quite* what we wanted. So use dirtyfb==1 to mean that the fb is not connected to any output that requires dirtyfb flushing, so that we can keep the underflow and overflow checking.

Add a way for userspace to specify the sequence number fence used to track completion of the submit. As the seqno fence is simply an incrementing counter which is local to the submitqueue, it is easy for userspace to know the next value. This is useful for native userspace drivers in a vm guest, as the guest to host roundtrip can have high latency. Assigning the fence seqno in the guest userspace allows the guest to continue without waiting for response from the host. Signed-off-by:

Any app controlled perfcntr collection (GL_AMD_performance_monitor, etc) does not require counters to maintain state across context switches. So clear them if systemwide profiling is not active. Signed-off-by:
-
Rob Clark authored
Add a SYSPROF param for system profiling tools like Mesa's pps-producer (perfetto) to control behavior related to system-wide performance counter collection. In particular, for profiling, one wants to ensure that GPU context switches do not effect perfcounter state, and might want to suppress suspend (which would cause counters to lose state). v2: Swap the order in msm_file_private_set_sysprof() [sboyd] and initialize the sysprof_active refcount to one (because the under/ overflow checking in refcount_t doesn't expect a 0->1 transition) meaning that values greater than 1 means sysprof is active.

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. But to be safe, also track unattributed faults.

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.
