714420a694 display: Put DCP to sleep if display is external
This stops DCP from killing our modeset if the connection cycles.

Also force a (potential) configure cycle if the display is external;
this makes sure updated stage2s will have a chance at fixing issues of
old stage1s. Modesetting is fast when it's the same mode as before.

8163883252 utils: Use exclusive load to wake up from WFE
Commit 9c795fbdbf introduced the pair of
WFE and SEV for spinlock, but it caused delays of tens of seconds. A
possible explanation for the delay is lack of data synchronization
barrier between the store instruction and SEV instruction.
Arm Architecture Reference Manual for A-profile architecture (issue H.a)
says:
> Arm recommends that software includes a Data Synchronization Barrier
> (DSB) instruction before any SEV instruction. The DSB instruction
> ensures that no instructions, including any SEV instructions, that
> appear in program order after the DSB instruction, can execute until
> the DSB instruction has completed.

However, inserting a DSB instruction still didn't resolve the delay.

The exclusive load is an alternative to the SEV instruction. The manual
says:
> ...However, in Armv8, when the global monitor for a PE changes from
> Exclusive Access state to Open Access state, an event is generated.

> This is equivalent to issuing an SEVL instruction on the PE for which
> the monitor state has changed. It removes the need for spinlock code
> to include an SEV instruction after clearing a spinlock.

As an additional benefit, the exclusive load is local to the PE and
eliminates spurious events for other PEs.

Trusted Firmware-A v2.6 also employs the same algorithm.

1ea31ae996 dart: Add setup of pre-allocated L2 tables for dcp/disp0
DART nodes for dcp and disp0 have pre-allocated L1 and L2 tables which
are annotated in the ADT. The pre-allocated memory is specified in
"pt-region-${DEVICE}". The first page is used as L1 table and the
following pages are used as L2 tables. The number of valid L2 tables is
specified in "l2-tt-${DEVICE}". The first entry identifies the region
and the second entry is the number of valid L2 tables.

iboot (macOS 12.3) inits just 2 L2 tables. Larger framebuffers require
more. By using the pre-allocated page tables we do not have worry about
keeping the memory mapped after m1n1 executes the next target.

c577e94d75 display: limit timing modes by framebuffer size
The reserved framebuffer on the Mac Studio is 0x854000 bytes. This is
too small for 1920x1200 with 4 byte per pixel. Setting 1920x1200 as
mode crashes dcp but not the actual display controller. The display
remains working and even comes back after display hotplug/power cycle.

8eeb7966aa hv: Refactor CPU switch logic, make hv.cpu() not exit shell
Get rid of the hv_rearm() thing (which was always a bit dodgy) and
instead properly make sure that all CPUs rendezvous when needed and
switch the active proxy thread without ever exiting exception context.

The Python side can now switch proxy context (by waiting directly for
a proxy boot) without having to exit out of the hypervisor callback,
so cpu() now works as a normal Python method.

Add a cpus() iterator so you can do things like:

>>> for i in cpus(): bt()

c746549c2e hv: Map RAM via tracer infra, handle carveouts in Python
Previously RAM was mapped ad-hoc, but this can end up interacting
poorly with the tracer infrastructure which we are now using for RAM
too. Move to mapping guest RAM via the tracer infra, and also unmap the
TZ carveouts in the Python side so it knows about them.

This is a HV ABI break.

fabe27e3f1 memory: Remap some carveouts as uncached
This fixes display DART real-time cache hits causing AMCC exceptions.

The relevant carve-outs have flags 0x60004016; 0x60004002 is used for
DCP which is non-realtime, so I'm guessing the '16' means we should map
it uncached.

cad8df30ce nvme: delete IO SQ/CQ when shutting down
This should not be required but it looks like the 12.1 ANS2 firmware
complains when NVME_CC.EN is cleared before the IO queues have been
deleted.

768be5bd58 sart: fix sart3_set_entry
writel_relaxed(val, addr) inside Linux but write32(addr, val) inside
m1n1 confused my muscle memory.

2ee920d229 sart: fix for 12.1
Looks like Apple decided to change the compatible to sart,coastguard and rely
on the sart-version ADT property to differentiate between M1 and M1 Pro/Max
instead. sart-version is already present in the 11.x ADT so let's just
always decide based on that.

fbc15bd77c payload: Consider an IMG4 blob as the end of payloads
When loading m1n1.bin, SEPFW follows m1n1 and thus will show up at
the payload offset if there are no payloads.

2bd7bf4020 afk: use version 3 for epic_sub_hdr
This drops the tx/rxcookie and accepts TYPE_NOTIFY in addition to
TYPE_REPLY for command replies to make the DCP code also work on 11.x.

It'll still complain about an unexpected message during init but work.
