182b4a2d25 drm/msm/dp: Add a missing semi-colon
A missing semicolon here causes my external display to stop working.
Indeed, missing the semicolon on the return statement leads to
dp_panel_update_tu_timings() not existing because the compiler thinks
it's part of the return statement of a void function, so it must not be
important.

  $ ./scripts/bloat-o-meter before.o after.o

  Total: Before=54440, After=54300, chg -0.26%

Add a semicolon so this function works like it used to.

ea9f337ce8 drm/msm/dp: reset dp controller only at boot up and pm_resume
DP_SW_RESET is the global SW reset that is used to initialize DP
controller. If DP_SW_RESET executed during connection setup,
two HPD related side effects may occurred,
1) pending HPD interrupts cleared unexpected
2) re start debounce logic which trigger another interrupt
This patch only issue DP_SW_RESET at boot up and pm_resume.
This patch also reinit video_comp before configure dp controller
to avoid missing VIDEO_READY interrupt.

c8d99bb938 drm/msm: Fix legacy relocs path
In moving code around, we ended up using the same pointer to
copy_from_user() the relocs tables as we used for the cmd table
entry, which is clearly not right.  This went unnoticed because
modern mesa on non-ancent kernels does not actually use relocs.
But this broke ancient mesa on modern kernels.

In function dsi_pll_calc_dec_frac we are calculating the decimal
div start parameter by dividing the decimal multiple by the
fractional multiplier: the remainder of that operation is stored
to then get programmed to the fractional divider registers of
the PLL.

It's useless to call div_u64_rem to get the remainder and *then*
call div_u64 to get the division result, as the first is already
giving that result: let's fix it by just caring about the result
of div_u64_rem.

lock initialized in this loop. Let's allocate a dynamic number of
lock_class_keys and assign them to each lock so that lockdep can figure
out an AA deadlock isn't possible here.

5f98b33b04 drm/msm: Fix races managing the OOB state for timestamp vs timestamps.
Now that we're not racing with GPU setup, also fix races of timestamps
against other timestamps.  In freedreno CI, we were seeing this path trigger
timeouts on setting the GMU bit, producing:

[drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0

and this triggered especially on the first set of tests right after
boot (it's probably easier to lose the race than one might think,
given that we start many tests in parallel, and waiting for NFS to
page in code probably means that lots of tests hit the same point of
screen init at the same time).  As of this patch, the message seems to
have completely gone away.

Before the offending commit in msm_atomic_commit_tail wait_flush was

wait_flush is also called at the beginning to ensure previous

For cmd panels the source of wait_flush is a ping-pong irq notifying

multiple waiting parties (new async committers) can proceed.

When configuring the tearcheck, the parameters for the engine were

configured to get the vsync indication from the TE GPIO input
because it was assumed that autorefresh could be enabled:
since a previous commit makes sure to disable the autorefresh bit
when committing to the cmd engine, it is now safe to just enable
the vsync pin input at tearcheck setup time (instead of erroneously
never enabling it).

Also, set the right sync_cfg_height to enable the DPU auto-generated
TE signal in order to avoid stalls in the event that we miss one
external TE signal: this will still trigger recovery mechanisms in
case the display is really unreachable.

Resetting the VBIF before power collapse is done to avoid getting

Especially on Adreno 508, the GPU will show lockups and very bad
slownesses after processing the first frame.

Avoiding to execute the RBBM SW Reset before suspend will stop the
lockup issue from happening on at least Adreno 508/509/512.

effectively nullifying the efforts.

implementation which are also used by older GPU generations
which do not have LLC and might introduce issues accidentally
and is not clean in a way that anymore additions of GPUs
supporting LLC would have to be guarded under ifdefs. So keep
the generic code separate and make the address space creation
A6XX specific. We also have a helper to set the llc attributes
so that if the newer GPU generations do support them, we can
