Instead of repeating the n64cart string all over the module use pr_fmt
macro and remove the duplicate string. Also, replace and with or in the
one of the error message.

This adds support for the Nintendo 64 console's carts. Carts are a
read-only media ranging from 8mb to 64mb.
Only one cart can be connected at once, and switching it requires a
reboot.
No module support to save RAM, as the target has 8mb RAM.

We tend to use output_format!=RGB as a shorthand for YCbCr, but
this fails if we have a disabled crtc where output_format==INVALID.
We're now getting some fail from intel_color_check() when we have:
hw.enable==false
hw.ctm!=NULL
output_format==INVALID
Let's avoid that by throwing INTEL_OUTPUT_FORMAT_INVALID to the
dumpster, and thus everything defaults to RGB when the crtc
is disabled.
This does beg the deeper question of how much of the state
should we in fact be validating when hw/uapi.enable==false.
And should we even be doing the uapi->hw copy when
uapi.enable==false? So far I've not been able to come up with
satisfactory answers for myself, so I'm putting it off for the
moment.

-Wunintialized was disabled in commit c5627461490e ("drm/i915: Disable
-Wuninitialized") because there were two warnings that were false
positives. The first was due to DECLARE_WAIT_QUEUE_HEAD_ONSTACK, which
was fixed in LLVM 9.0.0. The second was in busywait_stop, which was
fixed in LLVM 10.0.0 (issue 415). The kernel's minimum version for LLVM
is 10.0.1 so this warning can be safely enabled, where it has already
caught a couple bugs.

To support ww locking and per-object implemented in i915, GVT scheduler needs
to be refined. Most of the changes are located in shadow batch buffer, shadow
wa context in GVT-g, where use quite a lot of i915 gem object APIs.
v2:
- Adjust the usage of ww lock on context pin/unpin. (maarten)
- Rebase the patch on the newest staging branch.

Rather than break existing context objects by incorrectly forcing them
to rogue cache coherency and trying to assert a new mapping, read the
reg whitelist from the default context image.
And use gvt->gt, never &dev_priv->gt.

[Why]
mutex_lock() was introduced in dm_disable_vblank(), which could
be called in an IRQ context. Waiting in IRQ would cause issues
like kernel lockup, etc.
[How]
Handle code that requires mutex lock on a different thread.

When run igt@kms_vrr in a device that uses DCN2.1 architecture, we
noticed multiple failures. Furthermore, when we tested a VRR demo, we
noticed a system hang where the mouse pointer still works, but the
entire system freezes; in this case, we don't see any dmesg warning or
failure messages kernel. This happens due to a lack of vupdate_no_lock
interrupt, making the userspace wait eternally to get the event back.
For fixing this issue, we need to add the vupdate_no_lock interrupt in
the interrupt list.

The panel is able to work when dsi clock is non-continuous, thus
the system power consumption can be reduced using such feature.
Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags.
Also the flag actually becomes necessary after
commit c6d94e37bdbb ("drm/bridge/synopsys: dsi: add support for non-continuous HS clock")
and without it the panel only emits stripes instead of output.

The AFBC decoder used in the Rockchip VOP assumes the use of the
YUV-like colourspace transform (YTR). YTR is lossless for RGB(A)
buffers, which covers the RGBA8 and RGB565 formats supported in
vop_convert_afbc_format. Use of YTR is signaled with the
AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As
such, a producer would have to generate buffers that do not use YTR,
which the VOP would erroneously decode as YTR, leading to severe visual
corruption.
The upstream AFBC support was developed against a captured frame, which
failed to exercise modifier support. Prior to bring-up of AFBC in Mesa
(in the Panfrost driver), no open userspace respected modifier
reporting. As such, this change is not expected to affect broken
userspaces.
Tested on RK3399 with Panfrost and Weston.

The explicit out-fences in crtc are signaled as part of vblank event,
indicating all framebuffers present on the Atomic Commit request are
scanned out on the screen. Though the fence signal and the vblank event
notification happens at the same time, triggered by the same hardware
vsync event, the timestamp set in both are different. With drivers
supporting precise vblank timestamp the difference between the two
timestamps would be even higher. This might have an impact on use-mode
frameworks using these fence timestamps for purposes other than simple
buffer usage. For instance, the Android framework [1] uses the
retire-fences as an alternative to vblank when frame-updates are in
progress. Set the fence timestamp during send vblank event using a new
drm_send_event_timestamp_locked variant to avoid discrepancies.

Changes in v2:
- Use drm_send_event_timestamp_locked to update fence timestamp
- add more information to commit text
Changes in v3:
- use same backend helper function for variants of drm_send_event to
avoid code duplications
Changes in v4:
- remove WARN_ON from drm_send_event_timestamp_locked

Some drivers have hardware capability to get the precise HW timestamp
of certain events based on which the fences are triggered. The delta
between the event HW timestamp & current HW reference timestamp can
be used to calculate the timestamp in kernel's CLOCK_MONOTONIC time
domain. This allows it to set accurate timestamp factoring out any
software and IRQ latencies. Add a timestamp variant of fence signal
function, dma_fence_signal_timestamp to allow drivers to update the
precise timestamp for fences.
Changes in v2:
- Add a new fence signal variant instead of modifying fence struct
Changes in v3:
- Add timestamp domain information to commit-text and
dma_fence_signal_timestamp documentation

instead of fd
Every heap needs to create a dmabuf and then export it to a fd
via dma_buf_fd(), so to consolidate things a bit, have the heaps
just return a struct dmabuf * and let the top level
dma_heap_buffer_alloc() call handle creating the fd via
dma_buf_fd().

If we abort from the allocation due to a fatal_signal_pending(),
be sure we report an error so any return code paths don't trip
over the fact that the allocation didn't succeed.

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.

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.

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.

Lockdep complains about an AA deadlock when rebooting the device.

but task is already holding lock:

other info that might help us debug this:

This is because lockdep thinks all the locks taken in lock_crtcs() are
the same lock, when they actually aren't. That's because we call
mutex_init() in msm_kms_init() and that assigns one static key for every
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.

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.

We were using the same force-poweron bit in the two codepaths, so they
could race to have one of them lose GPU power early.
freedreno CI was seeing intermittent errors like:
[drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0
and this issue could have contributed to it.

Before the offending commit in msm_atomic_commit_tail wait_flush was
called once per frame, after the commit was submitted. After it
wait_flush is also called at the beginning to ensure previous
potentially async commits are done.
For cmd panels the source of wait_flush is a ping-pong irq notifying
a completion. The completion needs to be notified with complete_all so
multiple waiting parties (new async committers) can proceed.

The previous registers were *almost* correct, but instead of
PHYs, they were pointing at DSI PLLs, resulting in the PHY id
autodetection failing miserably.

There is HPD unplug interrupts missed at scenario of an irq_hpd
followed by unplug interrupts with around 10 ms in between.
Since both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts,
irq_hpd handler should not issues either aux or sw reset to avoid
following unplug interrupt be cleared accidentally. This patch
also postpone handling of irq_hpd until connected state if it
happened at connection pending state.
Changes in V2:
-- add postpone handling of irq_hpd until connected state
-- check DP_TRAINING_1 instead of DP_TRAINING_NONE
