at least for arc, it is required to set mps as 64 instead of 512 on
highspeed, or some accessories ignore incoming hid reports.

Themes like Adwaitapod, Themify, or FreshOS have
custom "lock screens" that are drawn on top of the
UI viewport.
Request a full skin update when unlocked, so you don't
have to press a button to make the hidden UI viewport
appear again.

The o32 ABI requires at least 8-byte alignment. This fixes
the float formatting weirdness seen in quake (FS#13821).

On FS#13821, a test build with -fstack-protector-all
(which adds 4 bytes of stack to each function, roughly)
overflowed the dircache stack on the Hifiwalker H2.
In my own testing, the dircache thread hit 94% stack
use on the Fiio M3K using the same settings.
That seems a bit too close to the limit, especially
since the dircache uses recursion and might consume
more stack space for deeply nested directories.
Adding 768 bytes should provide enough of a safety
margin. This increases the stack size from 1.25k to
2k on most targets, including all X1000 targets.

-fstack-protector only needs a small amount of runtime
support to work on native builds. It increases code size
by ~1.5% on ARM/MIPS; -fstack-protector-strong adds 3-4%.
This is disabled by default and must be enabled by passing
'--with-stack-protector' to configure.

PCM_SINK_NUM is 1, and cur_sink is initialized to 0. It can never be set
above 0. cur_sink can never be >= PCM_SINK_NUM, ie 0, but for some reason
the compiler thinks otherwise.... sometimes.
This only shows up on native ARM builds with GCC9.5.0

The recent pcm_mixer changes caused us to overflow IRAM by a whopping 8
bytes. This can _probably_ be mitigated with some clever reworking but
we were clearly already on the hairy edge.
Future pending changes are likely to increase IRAM pressure so even if
we solve this issue the odds are it will reappear at a future point.
(the ipod4g's framebuffer is 5KB. This doesn't affect the mini2g as its
framebuffer is under 4KB, and the ipodcolor doesn't put its framebuffer
in IRAM at all)

in order to implement iap digital audio interface, we have to send
a pcm packet every usb frame i.e. 1000 packets per second.
this rate can't be achieved with current standard request-response design,
even with fast_completion_handler.
this is why this new api is needed.

All that matters is that the _current_ sink is ready, not all possible
sinks. When switching sinks we will need to ensure tehy are initialized
before switching over.

Change the SAI FIFO threshold so that it is always
kept topped up at maximum; DMA needs to do single
transfers to the peripheral now. Ignore FEIF errors
since they seem to occur constantly with this setup
(though it's not exactly clear why this happens).
FEIF only indicates that the SAI made a DMA request
while the DMA FIFO is empty, which isn't a fatal error.
The DMA channel will simply service the request when
it is ready.
Keeping the SAI FIFO constantly full increases the
overall timing margin before underrun so losing the
FEIF info isn't a big deal in practice.

The purpose of the mutex is to make it possible to switch pcm sinks
safely, but pcm_play_lock/unlock and pcm_set_frequency need to be
called from IRQ context which is fundamentally incompatible with
our mutex implementation.
The proper path forward will be to promote the counter-based per-sink
lock/unlock implementation to the pcm core, and only allowing sink
switching when the counter is 0.
In the mean time, just remove sink_mutex entirely as the sink switching
code has yet to be committed.

It is required to call gfxExit() before exiting the app if gfxInit() was previously called. Otherwise, the GSP thread continues to run after the stack is invalidated.

Confirmed on iFlash-modded ipodvideo, USB mass storage connections
frequently fail with bus resets during mount on macOS, and trigger
"reset high-speed USB device" errors on Linux during sequential
reads.
The root cause is: storage_read_sectors() calls yield() via
ata_wait_intrq(), which switches to the main thread running
handle_usb_events() loop. This calls send_event(GUI_EVENT_ACTIONUPDATE),
triggering LCD redraw that takes approximately 110ms. This stalls the
ATA DMA completion, causing the USB bulk transfer to time out from the
host's perspective.
This commit removes the yield to prevent the reading thread from being
preempted by the lengthy LCD redraw during DMA completion.
This also improves sequential read throughput from ~13MB/s to ~18MB/s.
