A CPU read of DISPATCH_INDIRECT arguments waited only through the flush
hook, which waits for the ranges recorded work noted as pending writes.
An address-based store (FLAT/GLOBAL, or through a descriptor the
recompiler cannot resolve to a static buffer) is not recorded as a
pending write: its batch leases the registered allocations, and only the
guest pin waiter finished that batch. So the thread-dimension,
misaligned and disabled paths, the fill-kernel path and the device's CPU
fallback read the arguments from before an address-based producer ran.
GTA V (PPSA04264) dies loading Story on such a read: a 64-thread clear
kernel read {160, 288, 0xffffffff} as thread dimensions
(3x288x4294967295 groups), bytes its 1-thread setup kernel had not yet
overwritten with {n, 1, 1}, and threw "workgroup count
3x288x4294967295 exceeds device limits".
Every CPU read of dispatch arguments at execution now first finishes the
recorder up to the newest batch recorded with a lease
(Graphics::FinishLeaseWork). The group read-ahead still reads without
waiting; a dispatch it resolved is adopted only when the execution-time
read gives the same counts, and one that differs is dropped and counted
in the [groupcap] line. The device limit error names the argument
address and cpuReason, and the driver adds the queue, path and
read-ahead outcome. The [indirect] read time includes the lease wait,
and the [recorder] sync-site table records the offset of
FinishLeaseWork's caller. The CPU reads that still miss address-based
writes (indirect draw arguments and count, the copy kernel's count
record, the awaits-title checks) are listed in the technical debt.
IndirectArgumentsPendingProducer covers the execution-time CPU argument
reads on compute queues and the pending-label CPU fallback in the Vulkan
device. Its sixth case records a real argument label behind a host Vulkan
event in an earlier batch and an address-based producer in the later open
batch. The event releases only after that producer batch is submitted;
a bounded watchdog releases for cleanup but fails the case. It requires
a deferred producer lease, an unsubmitted producer at the argument
decision, cpuReason 2 and the fresh arguments and counter result. Small
valid stale counts keep a broken-wait control finite on every driver.
Exact CPU-reason and watchdog diagnostics identify the failing path. This
replaces a spinning workload whose earlier label could retire before
the fallback decision on lavapipe, allowing a false green with cpuReason 0.

Library functions and shader instructions were drawn on one y-axis with
ambiguous labels and overlapping fills. Each now gets its own panel and
scale, with implemented (solid) against declared (dashed); shaders gain
their declared total from the ISA list. Date labels are horizontal and
every day has a hover tooltip.

PPSA15552 passes matching front/up after a listener move; pick a perpendicular up hint instead of throwing so Dead Cells can keep running.

Since #7323 sceHmd2Initialize succeeds and sceHmd2Open returns a handle,
so PPSA01317 runs its PS VR2 set-up and aborts on
sceHmd2ReprojectionQueryBufferSizeAlign, which is not implemented
(reported in #6350). AnyPS5 has no PS VR2 or PC VR support, so
initialization returns libSceHmd's UNSUPPORTED_FEATURE (0x81110016)
again, as before #7323, and titles skip their VR set-up. sceHmd2Open
then returns NotInitialized. The reprojection size queries stay
unimplemented.

RADV initializes and fast-clears DCC keys with its fill_memory compute
kernel, which stores through a global address. Run as an ordinary
dispatch, its stores name no range. The DCC key tracking therefore saw
a key fill only once it had landed in guest memory, which could be
after later writes to the surface had already been recorded.
vkQuake (PPSA99010) hits this on every item pickup:
- the scene renders into a second color buffer;
- RADV's UNDEFINED -> GENERAL barrier fills color buffer 0's keys with
DCC_CLEAR_0000;
- a screen-effects compute pass writes color buffer 0;
- the UI pass draws on color buffer 0.
The keys landed while the UI pass was being recorded. The refresh took
them for a clear made after the compute pass, dropped its results and
cleared the image to black. For the length of the pickup flash the
scene was black, with only the HUD drawn.
The fill HLE now matches the 16-byte variant of the kernel as a fill of
min(threads * 16, user[4] + 16) bytes. The kernel takes its address in
user[2..3], its largest store offset in user[4] and its value in
user[5]. A key fill through it is handled where it is in the command
stream.
Primitive type 19 (DI_PT_QUADLIST, 0x13) is used by Unity and other engines for UI quads, sprites and font glyphs. Because Vulkan lacks native quad-list primitive topology, quad draws are expanded on the CPU into indexed triangle lists with 6 indices per 4-vertex quad, respecting the first/last provoking vertex configuration and discarding incomplete trailing vertices. Adds unit tests and documents the functional debt.
Devices with DenormFlushToZero for f32 run the mixed denormal-flush programs with and
without the hardware mode at startup; when every result matches, add, sub, mul, fma,
floor and ceil in the default rounding mode drop their software flush.
