Raw core overrides re-push after the curated settings, so a stale one silently
beats the UI with nothing on screen to explain it: the settings screen read SPU
Block Size = Safe for hours while config.yml read Mega.
Mega is the one that mattered. It produces very large compilation units, and those
are what fail AArch64 register allocation with "Cannot scavenge register without
an emergency spill slot" -- which is what put SPU threads on the interpreter
fallback at all. With it cleared, no block fails to compile and the fallback never
engages. Every "cannot be compiled" chased in these sessions traces back to it.
Cleared in every scope, because a title can pin a key the global also pins: Arkham
City carried Accurate SPU Reservations true as a raw per-title override against
false globally, so clearing one scope did nothing and the two readings looked
contradictory.
Per-title Accurate SPU Reservations values go too, except Web of Shadows, which is
the title it was measured on. Off is off-spec -- it forces the SPURS scheduler to
HLE and bypasses the reservation lock -- and a title left that way desyncs until
its SPU threads execute whatever they land on, which is how Arkham City ended up
dying with "Unknown STOP code: 0x0".
Adds CoreSettingOverrides.forgetEverywhere for the all-scopes case.
3072 was set to get the God of War 3 demo past an allocation failure, but that
failure was measured before the uninterruptible reclaim fix landed, and the cap is
not coordinated with the texture cache, which budgets itself up to 2560MB on
Android. Raising one without the other let the total grow with it: Batman: Arkham
City reached 5596MB resident against a 6246MB peak on a 7.2GB device and stalled
after a while, with no allocation failure to point at.
2048 is the value that shipped before, and it is where the sum of the two sat when
that game worked. Budgeting the cap and the cache together is the actual fix and
is not attempted here.
The RSX profiler was still recorded as a raw core override from the debugging
work, so config.yml read "RSX Profiler: true" while nothing in the UI said so --
the same divergence as the relaxed-ZCULL one, since overrides re-push at the tail
of applyTo. It writes a bucket report every 300 frames and keeps per-scope timers
on the RSX thread, which is not something to ship enabled. The first purge had
already marked itself done, so this takes a new key.
VRAM allocation limit is applied as VMA's pHeapSizeLimit, which makes it a hard
ceiling rather than an eviction threshold: once total allocations reach it VMA
returns OUT_OF_DEVICE_MEMORY however much the device has free. Lowering it does
not make the cache release earlier, it makes allocation fail earlier. The God of
War 3 demo was measured failing a routine 24MB request at 1024 while the process
held 1.6GB resident and 280MB in that pool, and failing at 2048 one screen later.
3072 leaves the caches room while keeping the bound that stops an unbounded quota
driving the process to 4.3GB and getting it killed.
The allocation failure now names the request size and the cap alongside it, since
"Out of video memory" alone cannot separate a full device from an artificial
ceiling, and those need opposite fixes.
Refusing outright skipped the allocator's own recovery. That path is "if
OUT_OF_DEVICE_MEMORY and vmm_handle_memory_pressure(...) succeeds, retry the
allocation", so returning false meant the retry never ran and the allocation died
having freed nothing: God of War 3 reached it with zero reclaim attempts and zero
recoveries logged.
Only the fatal branch needs the queue idle, which is what the flush inside it is
for. The rest is reachable while uninterruptible: the texture cache purges its
unreleased pool, and at severe it also drops unlocked sections. RPCS3 already runs
exactly that with no flush whenever pressure is non-fatal, so this is the existing
contract rather than a new risk. Severity is clamped below fatal so the
flush-dependent path stays unreachable.
Measured after: eviction runs and reports releasing resources, and the allocator
retries. God of War 3 still fails, but now for the honest reason -- the device is
out of memory, with 123MB free of 7.2GB and the emulator resident at 4.3GB -- and
not because nothing was ever given the chance to run.
on_vram_exhausted asserted that the renderer was interruptible. Eviction really
cannot run in that state, since it would touch resources the driver may still be
reading, but that is a reason to refuse rather than to kill the thread -- and
refusing is already the supported answer: the OOM path in VKDraw treats false as
using placeholder textures, which it notes can cause graphics glitches but
should not crash otherwise.
God of War 3 hit it by skipping the intro screens, which pushes a burst of surface
and texture allocation through a point where the renderer is uninterruptible. The
RSX thread died there, audio kept playing, and it presented as a hang. With the
refusal in place the same run reports the real problem instead:
VK_ERROR_OUT_OF_DEVICE_MEMORY from the allocator.
Which it genuinely is. VRAM allocation limit was also lowered from 2048 to 1024:
the first value was still above what the device could give us -- 5355MB resident,
99MB free of 7.2GB -- so the budget was never reached before the system ran dry,
which defeats its only purpose. It has to sit below what allocation can actually
satisfy, so eviction starts while there is still room to allocate.
Three things, all found by measurement after the interpreter fallback started
being used in anger.
Marking only the entry point made the interpreter release the thread after one
instruction, whereupon the recompiler tried the next address, failed the same way
and marked that too. 111 consecutive entries were recorded walking two blocks four
bytes at a time, each step paying a full failed LLVM compile. The failed set now
holds ranges, so a thread stays interpreted for the whole block and leaves when
execution genuinely moves past it: 111 markings became 1.
The range test then ran per interpreted instruction and took a reader lock each
time, which put shared_mutex::imp_lock_shared at 28% of the whole process against
23% for the interpreter itself. The extent is now cached on the thread when the
fallback engages, so the loop compares two integers.
The switch was also logged once per thread, but the flag is cleared on every exit,
so the guard fired on every re-entry: God of War 3 wrote thousands of lines a
second ping-ponging between two addresses. Removed; the block is still recorded
once when it is marked.
Separately, VRAM allocation limit was left at upstream's 65536 MB, which means no
limit and assumes a discrete card. Here the GPU shares system memory with the OS
and our own host allocations, so the texture cache is never asked to evict and
grows until allocation fails -- and failing is fatal: God of War 3 dies in
on_vram_exhausted on ensure(!vk::is_uninterruptible() && ...), because VRAM ran
out where the renderer cannot safely evict. Measured at the crash: 5355MB
resident, 99MB free of 7.2GB. 2048 leaves room for the guest's own memory, the
host caches and the OS.
The fallback flag was set once and never cleared, so a thread that met a single
block it could not compile interpreted everything it ran from then on. Correct,
but these are SPURS kernels doing real work, and Sonic Unleashed reached its
loading screen that way and then crawled through it.
The failed set holds entry points, so this keeps interpreting while pc sits on the
bad entry -- which is where a branch-to-self idle loop stays -- and releases the
thread as soon as execution moves past it. Only the block that cannot be compiled
is interpreted; the rest of the thread runs recompiled.
Leaving is safe at any instruction boundary, since all SPU state lives in
spu_thread, which is the assumption the JIT dispatch already makes. Re-entering
the bad block sets the flag again.
A block that fails to compile switches its thread to the interpreter. On ARM64
that fallback called spu_runtime::g_interpreter, which with a recompiler selected
is the LLVM-built interpreter, and calling it there executes nothing: measured a
million consecutive calls on Sonic Unleashed's stuck SPURS kernel without pc
moving once. The thread then spins in that loop forever at a fixed pc with no
flags set, which reads as a busy SPU and hangs the title with no diagnostic at
all. Any block that fails to compile landed there, so this was not one game.
old_interpreter is what the static decoder ultimately runs, through
tr_interpreter, and it is self-contained -- opcode table, thread, local store. Its
static-decoder-only check rejected exactly the case that needs it, so it now also
accepts a thread already marked for fallback.
Getting there also needed the give-up paths fixed: the TBL2/TBX2 retry could
return null with an empty error and fall through every branch unmarked and
unlogged, so nothing recorded that a block had been abandoned.
The stall dump now carries SPU event, MFC and interrupt state, which is what made
this findable: parked kernels showed pending=0 (no lost wakeup), intr_en was 0 on
healthy threads too (not interrupts), mfc_q was 0 everywhere (no stuck transfer),
and interp_fb=1 on the frozen thread pointed at the fallback itself.
Both waits in writer_lock are unbounded and silent. The acquire loop spins until
every range lock bit clears, and the range_lock path then spins until every
registered PPU thread reaches cpu_flag::wait. A thread that never gets there hangs
every other thread that takes a reservation, and leaves nothing behind: from
outside it reads as a clean guest deadlock with everything in a legitimate wait.
Both now log once, far past any plausible contention, naming the held range locks
or the PPU thread being waited on.
They paid for themselves immediately on Sonic Unleashed, which deadlocks at the
SEGA logo. Both stayed silent across several boots, which ruled out the VM lock
entirely -- worth having, since main_thread was pinned in cellSpursRemoveWorkload
carrying cpu_flag::memory without cpu_flag::wait, which looks exactly like this
bug and is not. The game hangs in a different state on different boots, so it is a
race elsewhere in SPURS.
Issue #16, both halves.
Installing a .pkg or .rap off a USB-OTG drive already went through the system
picker, and the descriptor it returns is handed to the native installer as a raw
fd, so a 40 GB package costs no copy. That holds only while the provider is
backed by real storage. The third-party USB-OTG and cloud apps people reach for
when the platform will not mount their drive return a PIPE, and every install
entry point seeks -- getFileType sniffs the magic and rewinds, package_reader
jumps around the archive -- so lseek failed with ESPIPE and a perfectly good
package was reported as unsupported or broken. Those descriptors are now
detected with the same lseek the core will make, and only those are copied to
real storage first, onto whichever of the emulator's own storage and the app
cache has more room. The copy is checked against the size the provider reported:
a short copy does not throw, it produces a truncated package that fails much
later as "broken", which reads as a bug report about the package.
Split releases picked through the system picker arrived in the order the user
tapped them, and installSplitPkg takes the order given as the part order, so
picking part 2 first extracted into a broken install rather than failing. Both
pick paths now sort the parts, digit runs numerically, since plain string order
puts part 10 between part 1 and part 2.
Installed titles were listed by title id alone -- NPUB90434, BLES01807 -- next
to an Uninstall button, which is where it hurt most: choosing which of two demos
to reclaim space from meant looking the ids up elsewhere. TITLE now comes out of
the install's own PARAM.SFO, read off disk rather than through the library cache
so a title the scanner has not seen yet is still named. The id stays on a second
line because patches, cheats and compatibility lists are keyed by it. Licence
files carry the same id inside their content id, so a .rap can name the game it
unlocks instead of being one of a row of indistinguishable hex strings.
The SFO field reader is the scanner's CATEGORY reader generalised rather than a
second copy of the 16-byte index-entry layout.
Accurate SPU Reservations off is worth a large amount in Spider-Man: Web of
Shadows and is not safe globally, so it goes in that title's own override rather
than the default.
Its SPURS reservation traffic serialises behind the global exclusive
vm::writer_lock that every reservation_op takes, which no amount of CPU can help:
all six SPU threads and several PPUs were measured yielding at the same rate with
18.8% of total CPU in sched_yield. Off, SPURS takes the lock-free path and
vm::writer_lock fell from 8.06% to 0.96%.
Kept per-title because it is off-spec -- upstream defaults it on, and Sonic
Unleashed fails EARLIER with it off, reaching neither the loading icon nor the
logo, which is consistent with the bypass being the SPURS area itself.
The seed writes only fields a title does not already carry, so a deliberate
change is never overwritten, and it runs once. Other regions of the same game
need their own entry.
Two things, both about the RSX waiting rather than working.
flush_command_queue ended by draining the present queue in case a queued frame
still held a ref to the command buffer just taken. It cannot: next() hands them
out from a 512 entry ring and the queued list is bounded at flip to
m_max_async_frames - 1, so the buffer being reused is hundreds of frames retired.
The guard was unreachable and the cost was not -- check_present_status pokes the
oldest queued frame's swap command buffer, and on Adreno vkGetFenceStatus blocks
until signalled rather than returning VK_NOT_READY, so a poll written to be cheap
became a full GPU sync. 1.32 times a frame at about 11ms: Fence poll 14.6ms ->
0.033ms, frame 44.5ms -> 36.6ms. Same fault as the two sites removed earlier;
this one sat inside flush_command_queue rather than on the present path. Ruled
out first: identical frame time at quarter resolution, and forcing the swapchain
pre-transform to match the surface left it unchanged.
The empty-ring yield is now charged to idle. It sits inside fifo_decode, which is
the enclosing scope of the whole run loop, so waiting on an empty ring was
reported as decode work -- Idle 0.003ms against FIFO decode 20.4ms, while a
native profile of the same thread put 34% of its cycles in sched_yield. The
bucket report and the profiler disagreed and the bucket report was wrong, which
has now produced two wrong conclusions in one session.
The 50us backoff in the FIFO_EMPTY path was added when the RSX thread was
measured spending 66% of its cycles in sched_yield on a machine starved for
cores: the affinity mask confined six SPU threads to four cores, and the
reservation path serialised everything behind a global lock, so a spinning RSX
took a core from threads that needed it.
Neither holds now, and the trade inverted with them. Measured after both were
fixed: 34% of eight cores busy, two to four threads runnable, five idle. Nothing
wants the core the sleep gives back, and the RSX sits on the frame's dependency
chain, so sleeping only delays it noticing the guest has produced work.
Also log the surface transform at swapchain creation. 30% of the frame is now in
check_present_status waiting on acquire_next_swapchain_image, which is not GPU
work -- a quarter-resolution run measured the same frame rate. Declaring IDENTITY
while the surface is rotated hands the rotation to the compositor, which can hold
images longer before releasing them for acquire. Logged rather than changed:
matching currentTransform means applying the rotation ourselves across the blit
and the overlay pass, and that is only worth doing if the two actually differ.
Dropped to 20 while the emulator was starved for cores, reasoning that a spinning
SPU steals a core from threads doing real work. Two things have changed
underneath that: the affinity mask no longer confines six SPU threads to four
cores, and the reservation path no longer serialises everything behind a global
lock. Measured after both, in game: 34% of eight cores busy, two to four threads
runnable, five idle, and no thread near saturation.
Tested at 100 and at 20 with no difference, which fits -- the wait is no longer on
the critical path, so how it waits does not matter. Upstream's value stands
rather than carrying a divergence that buys nothing.
The affinity migration turned the scheduler on so the big.LITTLE mask would
apply, keeping SPU and RSX off the A510s that run at roughly 27% of prime-core
capacity. That reasoning holds for one thread per core and breaks down at six.
Measured in game on a Snapdragon 8 Gen 2, reading the masks the threads actually
carry:
app cpuset (top-app) 0-7 Android grants every core
SPU[0..5] 3-6 six threads, four cores
rsx::thread 3-7
Six SPU threads sharing four cores get about two thirds of a core each, which is
worse than one thread owning an A510 outright, and it caps the emulator: the
device sat at 60% busy with cores 0-2 idle while frames were slow. Spider-Man:
Web of Shadows is visibly better at OS.
Worth being clear that the mask is ours and not Android's -- the app is in
top-app with all eight cores granted -- which is also why these devices are
reported to run better under native Linux, where no such policy is applied.
The other modes stay selectable for anyone whose device disagrees.
A DualShock 3 sends pressure bytes in every packet. The press setting governs how
much of the buffer the game is told is valid, not whether the pad produced the
values, so clearing the area diverges from the hardware: a game that reads a
pressure byte without having asked for press mode gets 0 where it would see a
press on a console.
Spider-Man: Web of Shadows does exactly that for R2. Tracing both entry points
showed it never calls cellPadInfoPressMode or cellPadSetPressMode, so the setting
stays at 0, yet it reads the R2 pressure byte to decide whether the trigger is
held. R2 did nothing in that game while every other button worked, from the
controller and from the touch overlay and after remapping to a different physical
button, because the digital bit was delivered correctly the whole time and was
never what the game looked at.
len is unchanged, so a game that honours it sees what it saw before.
The out-buffer check answers 'unlikely to be a loop', and that answer is not
free. It resets the spin count and leaves the busy-waiting switch at umax, so the
caller skips busy_wait, skips the sleep path, and returns immediately: the SPU
re-executes GETLLAR at full rate with no backoff. The spin count never reaches 4,
so the spin optimisation is never evaluated, and the 400ms fallback that would
force a sleep is never reached either. One SPU in that state holds a core flat
out, and the setting meant to control this has nothing to act on.
Spider-Man: Web of Shadows sits in that case. Its GETLLAR sites use an LSA in the
top 64K of local store, which is what the check looks for, and process_mfc_cmd
measured 55% of all CPU across the process while the game ran at 10-15fps.
Re-entering the same site with the same stack 32 times is itself the evidence
that it is a loop, whatever the LSA looks like. After that the verdict is dropped
and the normal spin detection decides between busy-waiting and sleeping. Any real
change of site or stack resets the count, so a genuine OUT buffer still gets the
original treatment.
SPU GETLLAR Busy Waiting Percentage defaults to 100 upstream, meaning always
busy-wait. That suits a desktop, where the SPU threads have cores of their own
and spinning costs nothing else. Here six of them share eight cores with the PPUs
and the RSX, so a spinning SPU takes a core from the threads doing the work.
Measured on Spider-Man: Web of Shadows: process_mfc_cmd accounted for 55% of all
CPU across the process, and making its inner loop cheaper did not move the frame
rate -- the loop just ran more iterations in the same wall clock. That is what
identified it as a spin rather than as work, after two rounds of optimising the
iteration itself.
20 still favours a short busy-wait, so a reservation that frees quickly is caught
without a scheduler round trip, and only a wait that history says is long goes to
sleep. A deliberate change in All Core Settings still wins, since core overrides
replay after this.
Gating the check on getllar_spin_count was not enough. That counter is reset from
several other paths, so it is frequently zero and the callstack was still rebuilt
constantly: measured 19.6% of all CPU inclusive in dump_callstack_list, the
largest single item after process_mfc_cmd itself.
Key on the values the answer actually depends on instead -- pc, the stack pointer
and the link register -- and recompute only when one of them moves. Only the
innermost frame is ever used, so that is all the memo keeps.
A stale answer across an unrelated LS write is acceptable here. This decides only
whether the address looks like a caller's OUT buffer, on a heuristic whose own
comment calls it 'unlikely to be a loop'.
The out-buffer check in the GETLLAR spin detector rebuilt the callstack on every
iteration of a busy-wait loop. dump_callstack_list walks the stack and calls
is_exec_code for each candidate, which allocates a vector<bool> and scans for
branch targets, so the cost is large next to what it decides.
On a whole-process profile of Spider-Man: Web of Shadows those three came to
about 14% of all CPU -- more than the RSX thread spent on the frame -- because
the game's SPU code spins on GETLLAR with an LSA in the top 64K of local store,
which is exactly the case the check looks at.
Once per sequence is enough. pc, ch_mfc_cmd.lsa, gpr[1] and addr are all compared
against the previous iteration a few lines above and any change resets the
sequence, so the callstack cannot move underneath a spin.
sched_yield does not idle a core. With every core already busy it returns almost
immediately and the RSX thread takes it again, running flat out producing
nothing. A native profile of Web of Shadows put 66% of this thread's cycles in
sched_yield and its kernel path against 9% in run_FIFO, which the bucket profiler
reports as a busy RSX because the yield happens inside the fifo_decode scope.
That is not free even with an empty ring. The RSX affinity mask covers the whole
fast cluster while the SPU mask is that cluster minus the prime core, so any of
this that lands off the prime core is taken from the SPU threads, and those are
what the frame is actually waiting on at 61% of all CPU.
The spin still runs 64 times before sleeping, so a producer that is merely slow
is met without a scheduler round trip. Only a ring that has genuinely gone quiet
reaches the 50us sleep, which is far below the frame times where this matters.
Android only.
A query that begins inside a render pass instance has to end inside that same
instance. Ending the pass underneath an open one leaves it permanently
unavailable, and on Turnip it takes the device with it, reported later against
poke_query because that is the first call that waits on a result.
Queries do begin inside render passes here. VKDraw only lifts them out when
use_strict_query_scopes() is set, and that is wired to Strict Rendering Mode, a
user performance setting rather than a driver quirk, so it is off for almost
everyone.
Twenty-one call sites end a render pass and only one, in VKDraw, ever paired
itself with a cleanup. change_image_layout alone ends 41 passes a frame in Web of
Shadows, and any of them can land while a query is open, which is why fixing the
two sites in the query pool moved the device loss from one minute to nearly three
rather than removing it. Holding the invariant in end_renderpass covers all of
them, including any added later.
The VKDraw site now cleans up before the pass ends rather than after, which is
the order the spec asks for; its own call becomes a no-op.
The migration that turned relaxed ZCULL on recorded it twice: once in the curated
store and once as a raw core override. The migration that turned it back off only
corrected the curated field, so the two stores disagreed, and the override is the
one that reaches the core -- overrides re-push at the tail of applyTo, after the
curated store has written the setting.
The toggle therefore read OFF while config.yml read 'Relaxed ZCULL Sync: true' on
every boot, with no way to change it from the UI. That is not cosmetic: relaxed
sync is what allows queries to be read while still pending, which is the path
behind the 'Dubious query data pushed to cond render' warnings, and it also
selects emulated predication in the VK backend.
Emulated conditional rendering exists for hardware that never had the extension.
Turning the extension off as a driver workaround enabled it by accident, because
both are selected by the same test, and the two halves do not fit together:
begin_conditional_rendering returns early without building m_cond_render_buffer,
while the vertex shader still reads that buffer at offset 0. It gets a zeroed
scratch buffer, predicates every draw away, and the game renders black with audio
and overlays still running. The all-ones word that disables predication sits at
offset 4 and is never reached, since the fallback leaves hw_cond_active set.
Off on these drivers means occlusion results stop culling draws, which is the
trade the workaround already documents.
The vendor comes off the GPU rather than from get_driver_vendor(), whose cached
value is not assigned until later in the same function and would still hold the
previous device's.
The existing gate covered only the proprietary driver and said Turnip was left
alone until there was evidence about it. There is now.
Web of Shadows loses the Vulkan device about a minute into gameplay on Turnip 26
/ Adreno 740. The assertion names poke_query, which is the first call that reads
a result rather than the one at fault. Conditional rendering is the only place we
record vkCmdCopyQueryPoolResults with VK_QUERY_RESULT_WAIT_BIT, and that form
makes the GPU block until the query resolves, so a query that never resolves
hangs the device instead of the caller and the watchdog ends the session. The
same run logged 169 'Dubious query data pushed to cond render' warnings, which is
this code being handed queries that are still pending.
It is also the churn: the aggregation barriers closed 42 of the 91 render passes
in a measured frame, and ending a pass on a tiler costs a tile store and reload.
Both drivers now fall back to thread::begin_conditional_rendering, the path
desktop already takes wherever the extension is absent.
Fixing the device loss by ending the render pass before vkCmdCopyQueryPoolResults
introduced a hang in its place. A query that begins inside a render pass instance
has to end inside that same instance; ending the pass underneath an open one
leaves it permanently unavailable, so get_query_result spins on poke_query with
no way out and the RSX thread stops.
Nothing reported it. The submit-time ensure() only checks that the query was
closed, and end_occlusion_query closes it a moment later, so the assert passes
while the result never arrives. The stall detector runs from do_local_task in the
FIFO loop, which the spin has already left, so the profiler charged the wait to
FIFO decode and the frame read as CPU-bound -- 93% in a bucket that was really
the thread sitting in sched_yield. Web of Shadows locked up this way after
reaching gameplay, audio and vblank still running.
Both sites that end a pass from the query path now close an open query first,
which keeps begin and end within one pass. The query is cut short, as it is
anywhere do_query_cleanup is used.
The wait itself is now bounded as well. It warns at one second and abandons at
three, using whatever the query holds: wrong culling for a frame is a better
failure than a thread that never returns, and the log names the cause.
The drain fix made every path that can idle or block publish GET immediately,
which is required for correctness: a producer waiting on ring space needs to see
the progress we made before we stopped consuming.
It publishes far more often than that requires. The empty and busy cases return
straight to the run loop, so a ring that has gone quiet re-enters them once per
iteration with GET unmoved. Web of Shadows measured 137000 loop iterations per
frame against 46000 method dispatches; the remaining 91000 were republishing a
value the guest already had.
GET shares a 64-byte line with put, which the guest PPU writes from another
cluster, so each of those is a coherence miss taken against the thread feeding
the ring. The cost lands on the producer rather than on the RSX, which is why it
presented as a freeze with sound still playing: the PPU stalls on the contended
line while threads that never touch it keep running.
GET is ours to write, so tracking the last published value and skipping an
unchanged store keeps the guarantee -- progress is still announced exactly once
after the last advance -- without the repeats.
vkCmdCopyQueryPoolResults must be recorded outside a render pass instance. This
recorded it inside one, with a comment saying we are technically supposed to stop
the pass first but that it does not matter on IMR hardware. It is not a
technicality -- inside a pass it is undefined behaviour, and a desktop GPU
tolerating it says nothing about a tiler.
This device lost the Vulkan device over it. The fault surfaced later, in
poke_query, because that is the first call that waits on a GPU result, so it read
as the query READ being at fault when the damage was done at record time. Only
the RSX thread died, so the process kept running with audio and vblank alive and
it presented as a hard freeze rather than a crash. Verified gone: zero device
losses on a run that previously died within a minute.
The pass is ended only when one is actually open, on a path that already stalls
for a GPU result, so the flush the upstream comment worried about is paid where
we were blocking anyway -- and disabling occlusion queries is not the
alternative, measured here at 80ms frames with broken visuals.
The two by-pass tables were joined on counters that reset at different points.
tick_frame runs from on_frame_end, before flip; the GPU timer rotates its slot at
the top of flip and then drops every non-frame region on the fresh slot, which is
flip's own overlay and calibration passes -- and those still incremented the CPU
counter. So the CPU ordinal ran ahead by the number of present-path passes and
the two tables described different passes. A whole anomaly came out of that: a
pass whose GPU cost was joined to a neighbour's workload read as 36x the per-draw
cost of its peers. The comment claiming both reset on the same boundary was
wrong. Reset where the GPU slot actually rotates instead.
Also adds a Storage Access Framework route to the package installer. The in-app
browser walks java.io.File, which only reaches storage this process can open by
path, so a .pkg on a USB-OTG drive or an SD card was unreachable and had to be
copied to internal storage first. Packages are handed over as the descriptor SAF
already returned -- the native side takes a raw fd, so nothing is copied and a
4 GB package costs no extra space; licences are 16 bytes and their installer
wants a real file, so those alone are staged.
The low-memory serialisation added three days ago holds a std::mutex across the
LLVM compile itself. A worker that hits LLVM's fatal handler leaves through
pthread_exit, and bionic unwinds nothing on that path, so the mutex stays locked
by a thread that no longer exists and every remaining worker waits on it for the
rest of the session. Memory only falls as modules accumulate, so the tight-memory
branch is likeliest late in a run -- which is why it reads as the PPU cache
getting stuck at the very end, and why dropping to the interpreter avoids it.
Reported as Saint Seiya: The Sanctuary never finishing its module cache. A claim
taken by compare-and-swap and waited on with a timeout costs a stranded claim a
wait rather than the session; the memory back-pressure either side of it is
unchanged. Third time this fork has been bitten by an unbounded wait around a
thread bionic can kill without unwinding.
overlay_audio.cpp already accounts for a platform with no video source; the same
ensure() was left in overlay_video.cpp. Android's make_video_source returns
nullptr, and overlay_save_dialog builds a video_view for EVERY entry on all three
of its paths, so opening a save list aborted as soon as there was one save to
draw. It presents as the save menu never opening -- reported against Ratchet &
Clank: Tools of Destruction and Devil May Cry 4, and against Web of Shadows,
which stalls only once a save exists to be listed. Bundling the overlay icons
was necessary but not sufficient: the dialog still could not survive drawing.
The still image is what an entry needs; the animated ICON1.PAM is the part no
backend here can supply. Also dumps SPU thread pc and block hash alongside the
PPU dump when frames stop, which is what named the SPURS kernels as idle rather
than spinning in guest code.
overlay_controls.cpp loads a fixed set of PNGs -- button glyphs, save.png,
new.png, spinner -- through fs::get_config_dir() + Icons/ui/. Desktop ships them
beside the binary; nothing put them on Android, so every load failed and the log
said so on each boot. The visible cost was cellSaveData's list: it is a native
overlay that draws its rows with save.png/new.png, so the load-save menu a game
opens never appeared. Reported against Ratchet and Clank: Tools of Destruction
and Devil May Cry 4, both fine on emulators that ship the icons.
Bundled from bin/Icons/ui and staged into config/Icons/ui once, revision-guarded,
before the core can draw its first overlay.
The nineteen translation files were ARMSX2-era: about nine hundred of their keys
still existed and showed the old PS2 wording -- worse than the English fallback,
which is at least right -- and roughly eight hundred current keys had no
translation at all. Regenerated all nineteen from the 1041-key map, batch plus
per-line retry, with every %s/%d checked against the source so no broken format
string ships. A string that would not translate is omitted and falls back to
English rather than shipping wrong.
The memory-card and PNACH patch screens were PS2 concepts with no PS3 counterpart
and no caller left -- the drawer had already been cleaned, so they were dead code
holding dead strings. The PNACH downloader went with its only consumer, and the
PCSX2-Android.ini seed could never exist under this package. The session log now
announces ARMSX3_INIT instead of PCSX2_INIT, which had every bug report opening
with the name of a different emulator.
The English map drops 46 PS2 strings and 619 orphans nothing references (1705 ->
1041 keys), rewords the four live strings that still said memory card, and renames
about.pcsx2.* to about.rpcs3.* to match what they already said.
