sceAgcCbCondWrite writes the 9-dword COND_WRITE packet: poll a memory
dword, compare it masked with the reference, and write a dword to memory
on a match. sceAgcCbCondWriteGetSize returns its 36 bytes.

COND_WRITE (opcode 0x45) with a memory poll and a memory destination is
validated and executed: the driver drains the queue like WRITE_DATA,
reads the poll dword through the range synchronization, compares it
masked with the reference like a 32-bit WAIT_REG_MEM, and writes the
data dword on a match. Register polls and register or scratch
destinations are rejected.

The masked case loaded EXEC from a scalar literal. A scalar mask is read
by subgroup lane, so on a host whose subgroups are narrower than the wave
(llvmpipe: 8 lanes) lane 16 took bit 0 and stayed active. v_cmpx_gt_u32
on the thread id gives the same low 16 lanes on any subgroup size.

Both swap data0 with the dword at addr + offset0 and data1 with the dword
at addr + offset1, and return the two previous values in vdst and vdst + 1.
The offsets are scaled by 4 bytes, or by 256 bytes for the st64 form.
Each location goes through the existing SharedAtomicSwap32.
An encoding whose two offsets are equal is rejected at decode time.

sceAgcAsyncCondExecPatchSetCommandAddress and
sceAgcAsyncCondExecPatchSetEnd patch the COND_EXEC packet like their
graphics counterparts, since sceAgcAcbCondExec writes the same packet
as sceAgcDcbCondExec. Both variants share one implementation, as the
REWIND patches do.

The query writes the maximum resource name length (0xfc) through its
output pointer and returns 0, as prosper does from a title's registration
configuration. The parameter follows the SDK wrapper
sce::Agc::ResourceRegistration::getMaxNameLength(unsigned int*). Resource
registration itself stays unavailable.

PPSA22520 lists libSceNgs2.prx, not libSceNgs2.native.prx, among its needed
modules, so its NGS2 imports did not resolve against the dummy module. Both
modules are now built by add_sce_ngs2_library from the same sources, as
libSceFont and libSceFont.native share add_sce_font_library, and the render
tests also run against libSceNgs2.

Rack 0x2001 is created with its option layout and KytyPS5's defaults, takes
the setup (0x20010000) and I3DL2 (0x20010001) voice params and reports the
common voice state. The voice mixes its inputs and runs a Freeverb-style
approximation driven by the I3DL2 parameters: room and room HF, early
reflections and their delay, late reverb and its pre-delay, decay time and
HF ratio, and diffusion. Out-of-range params throw, param changes keep the
tail, a stop or kill clears it, and the tail ends once it decays below
1e-20. The console's algorithm is unknown; the approximation is recorded in
TechnicalDebt. The test context buffer pool grows to 64.

Mastering voice param 0x30000004 sets a full-band and an LFE level. They
scale the mastering voice when it is mixed into the render buffer, the LFE
level on channel 3 of 6- and 8-channel voices. Non-finite levels are
invalid arguments.

SDL_CreateWindow with SDL_WINDOW_VULKAN loads and queries the Vulkan loader
while the render thread can be inside vkCreateInstance. On Windows the two
together intermittently made the NVIDIA ICD fail instance creation (-3) and
the loader return VK_ERROR_INCOMPATIBLE_DRIVER. libSceAgcDriver now exports
a loader lock that the VulkanDevice constructor and DisplayWindow::create
both hold.

A port without an SDL device slept one block after its previous output on
every call. Rounded-up sleeps held titles that write several ports from one
thread below real time. Such ports now keep a virtual queue that drains in
real time and only wait when it holds more than the target latency.

The SDK 9 libc.prx heap maps its arenas with flag 0x8000, which threw as
an unsupported flag. The flag is ignored for this function, as sharpemu
does; other unknown flags still throw.

On Windows APS5_VABI is sysv_abi, so the exports did not convert to
plain function pointers and the test did not compile.

MinGW rejects alignas(65536) on a global, as COFF objects allow at most
8 KiB, so the 64 KiB-aligned texels are taken from a larger buffer.

A sampler descriptor with BORDER_COLOR_TYPE 3 names an entry of the border
colour table, but the hardware reads it only through an axis that addresses
the border (clamp modes 4 to 7). DecodeSamplerResource threw for every
table border colour, so a sampler that clamps to the edge on all axes, as
PPSA21567's Armadillo Challenge 2 compute shader uses, stopped the title
although its border colour is never sampled. It now throws only when an
axis uses a border mode, the same rule the colour compare emulation
applies, and otherwise uses a fixed Vulkan border colour.
