2d0539575a drm/i915: Fix MSO vs. bigjoiner timings confusion
When calculating pipe_mode and when doing readout we need
to order our steps correctly.

1. We start with adjusted_mode crtc timings being populated
   with the transcoder timings (either via readout or
   compute_config(). These will be per-segment for MSO.
2. For all other uses we want the full crtc timings so
   we ask intel_splitter_adjust_timings() to expand
   the per-segment numbers to their full glory
3. If bigjoiner is used we the divide the full numbers
   down to per-pipe numbers using intel_bigjoiner_adjust_timings()

During readout we also have to reconstruct the adjusted_mode
normal timings (ie. not the crtc_ stuff). These are supposed
to reflect the full timings of the display. So we grab these
between steps 2 and 3.

The "user" mode readout (mainly done for fastboot purposes)
should be whatever mode the user would have used had they
asked us to do a modeset. We want the full timings for this
as the per-segment timings are not suppoesed to be user visible.
Also the user mode normal timings hdisplay/vdisplay need to
match PIPESRC (that is where we get our PIPESRC size
we doing a modeset with a user supplied mode).

And we end up with
- adjusted_mode normal timigns == full timings
- adjusted_mode crtc timings == transcoder timings
  (per-segment timings for MSO, full timings otherwise)
- pipe_mode normal/crtc timings == pipe timings
  (full timings divided by the number of bigjoiner pipes, if any)
- user mode normal timings == full timings with
  hdisplay/vdisplay replaced with PIPESRC size
- user mode crtc timings == full timings

Yes, that is a lot of timings. One day we'll try to remove
some of the ones we don't actually need to keep around...

osnoise's runtime and period are in the microseconds scale, but it is
currently sleeping in the millisecond's scale. This behavior roots in the
usage of hwlat as the skeleton for osnoise.

Make osnoise to sleep in the microseconds scale. Also, move the sleep to
a specialized function.

ab2f993c01 ftrace: Remove unused ftrace_startup_enable() stub
When building with clang + CONFIG_DYNAMIC_FTRACE=n + W=1, there is a
warning:

  kernel/trace/ftrace.c:7194:20: error: unused function 'ftrace_startup_enable' [-Werror,-Wunused-function]
  static inline void ftrace_startup_enable(int command) { }
                     ^
  1 error generated.

Clang warns on instances of static inline functions in .c files with W=1
after commit 6863f5643d ("kbuild: allow Clang to find unused static
inline functions for W=1 build").

The ftrace_startup_enable() stub has been unused since
commit e1effa0144 ("ftrace: Annotate the ops operation on update"),
where its use outside of the CONFIG_DYNAMIC_TRACE section was replaced
by ftrace_startup_all().  Remove it to resolve the warning.

However it is located in a hot path so inlining it is important.
But forcing inlining of the entire function by using __always_inline
leads to increasing the text size by approx 20 kbytes.

Instead, split the fonction in two parts, one part with the likely
fast path, flagged __always_inline, and a second part out of line.

With this change, on a powerpc32 with CONFIG_CC_OPTIMISE_FOR_SIZE
vmlinux text increases by only 1,4 kbytes, which is partly
compensated by a decrease of vmlinux data by 7 kbytes.

On ppc64_defconfig which has CONFIG_CC_OPTIMISE_FOR_SPEED, this
change reduces vmlinux text by more than 30 kbytes.

b61edd5774 eprobes: Remove redundant event type information
Currently, the event probes save the type of the event they are attached
to when recording the event. For example:

  # echo 'e:switch sched/sched_switch prev_state=$prev_state prev_prio=$prev_prio next_pid=$next_pid next_prio=$next_prio' > dynamic_events
  # cat events/eprobes/switch/format

 name: switch
 ID: 1717
 format:
        field:unsigned short common_type;       offset:0;       size:2; signed:0;
        field:unsigned char common_flags;       offset:2;       size:1; signed:0;
        field:unsigned char common_preempt_count;       offset:3;       size:1; signed:0;
        field:int common_pid;   offset:4;       size:4; signed:1;

        field:unsigned int __probe_type;        offset:8;       size:4; signed:0;
        field:u64 prev_state;   offset:12;      size:8; signed:0;
        field:u64 prev_prio;    offset:20;      size:8; signed:0;
        field:u64 next_pid;     offset:28;      size:8; signed:0;
        field:u64 next_prio;    offset:36;      size:8; signed:0;

 print fmt: "(%u) prev_state=0x%Lx prev_prio=0x%Lx next_pid=0x%Lx next_prio=0x%Lx", REC->__probe_type, REC->prev_state, REC->prev_prio, REC->next_pid, REC->next_prio

The __probe_type adds 4 bytes to every event.

One of the reasons for creating eprobes is to limit what is traced in an
event to be able to limit what is written into the ring buffer. Having
this redundant 4 bytes to every event takes away from this.

The event that is recorded can be retrieved from the event probe itself,
that is available when the trace is happening. For user space tools, it
could simply read the dynamic_event file to find the event they are for.
So there is really no reason to write this information into the ring
buffer for every event.

302e9edd54 tracing: Have traceon and traceoff trigger honor the instance

cccc71b552 drm/i915: Avoid negative shift due to bigjoiner_pipes==0
bigjoiner_pipes==0 leads bigjoiner_master_pipe() to
do BIT(ffs(0)-1) which is undefined behaviour. The code should
actually still work fine since the only place we provoke
that is intel_crtc_bigjoiner_slave_pipes() and it'll bitwise
AND the result with 0, so doesn't really matter what we get
out of bigjoiner_master_pipe(). But best not provoke undefined
behaviour anyway.

53581504a8 drm/i915: s/JSP2/ICP2/ PCH
This JSP2 PCH actually seems to be some special Apple
specific ICP variant rather than a JSP. Make it so. Or at
least all the references to it seem to be some Apple ICL
machines. Didn't manage to find these PCI IDs in any
public chipset docs unfortunately.

The only thing we're losing here with this JSP->ICP change
is Wa_14011294188, but based on the HSD that isn't actually
needed on any ICP based design (including JSP), only TGP
based stuff (including MCC) really need it. The documented
w/a just never made that distinction because Windows didn't
want to differentiate between JSP and MCC (not sure how
they handle hpd/ddc/etc. then though...).

2ff5560e23 drm/i915/dmc: Do not try loading wrong DMC version
Checking by >= DISPLAY_VER(12) made sense when the support for Tiger
Lake was added. However now it only leads to wrong behavior when adding
more platforms since it's expected they either don't have DMC to load
or they have their own blob.

riscv: fix oops caused by irqsoff latency tracer
The trace_hardirqs_{on,off}() require the caller to setup frame pointer
properly. This because these two functions use macro 'CALLER_ADDR1' (aka.
__builtin_return_address(1)) to acquire caller info. If the $fp is used
for other purpose, the code generated this macro (as below) could trigger
memory access fault.

[    0.046402][    T0] [<ffffffff80003b94>] restore_all+0x12/0x6e

This because the $fp(aka. $s0) register is not used as frame pointer in the
assembly entry code.

	resume_kernel:
		REG_L s0, TASK_TI_PREEMPT_COUNT(tp)
		bnez s0, restore_all
		REG_L s0, TASK_TI_FLAGS(tp)
                andi s0, s0, _TIF_NEED_RESCHED
                beqz s0, restore_all
                call preempt_schedule_irq
                j restore_all

To fix above issue, here we add one extra level wrapper for function
trace_hardirqs_{on,off}() so they can be safely called by low level entry
code.

b4eb76d82a drm/i915/dg2: Skip output init on PHY calibration failure
If one of our PHYs fails to complete calibration, we should skip the
general initialization of the corresponding output.  Most likely this is
going to happen on outputs that don't actually exist on the board; in
theory we should have already decided to skip this output based on the
VBT, but we can't always rely on the VBT being accurate.

2656fd230d drm/amdgpu: Exclude PCI reset method for now.
According to my investigation of the state of PCI
reset recently it's not working. The reason is
due to the fact the kernel PCI code rejects SBR
when there are more then one PF under same bridge
which we always have (at least AUDIO PF but usually
more) and that because SBR will reset all the PFS
and devices under the same bridge as you and you
cannot assume they support SBR.
Once we anble FLR support we can reenable this option as
FLR is doable on single PF and doens't have this
restriction.
