macos_gs_traps converts the forms Wine's ntdll in Prospero Win (PPSA99995) uses, a store, an ALU read and a register-address form shorter than a jump, and checks that each becomes ud2 and NOP padding of its own length before the next instruction, with none of the original bytes left.
On x86-64 macOS, including under Rosetta, the host owns GS (it holds the
pthread TSD base, which the macOS TLS stubs read), so a guest instruction
that reads or writes through GS cannot be translated, and the TLS scan
refused the whole module. Prospero Win's (PPSA99995) Wine ntdll has six.
Overwrite each in place with ud2 and NOP padding of its own length, as the
Windows writer does in #6102, and refuse one that is also an AMD-only
trampoline site.
The data-hit verification keeps this branch's pending-span query on its ShaderMemory and takes #5958's CaptureInvocation, which retries a capture with converted samples.
Keeps this branch's tagVariantRuns declaration next to main's dumpRequest suffix parameter in Driver.hpp, and reads #6232's pointer-chain test words from its table's snapshot, where this branch keeps them.
The first vouch's pending-write query created the driver, and the driver's construction ends a guest-allocation mutation, which moves the layout generation the stamp holds. The second vouch then refused the table on a layout change the queued draws didn't make. The test now creates the driver first, so both vouches compare the stamp against the layout the draws run under.
A shared mapping is a view of a file section created on the descriptor's
handle, read-write when the descriptor is, otherwise read-only. A private
mapping is a copy of the file read at mmap, as POSIX allows. Anonymous
shm_open objects and JIT shared memory descriptors are temporary files on
Windows, so mmap now maps them too (it failed with EOPNOTSUPP before).
mprotect of a mapped view above the view's protection fails with EACCES
before any bookkeeping changes. The cases Windows cannot represent are
listed in the libkernel debt.
Dusklight (PPSA99305) uses SQLite in WAL mode, which maps its -shm file.
On Windows main f0634088b every start logged "Failed to start
transaction: disk I/O error" for its Dawn and pipeline caches (3 of 3
runs); with this change the caches initialise and their WAL files fill
(4 of 4 runs). The title reaches its menu either way.
A shared mapping may end inside the 16 KiB page that holds the end of
the file, as POSIX mmap allows: the view ends with the file's last 4 KiB
host page, which Windows zero-fills past the end, the rest of the guest
page is private zero pages, and the file never grows. A mapping that
reaches a whole page past the end still fails with EOPNOTSUPP.
PS5LM Plus (PPSA99581) loads its model with llama.cpp, which maps the
whole GGUF file shared and read-only. With a 491,400,032-byte model,
Windows main 5de7a46e0 and this change without the last page logged
"llama_model_load: error loading model: mmap failed: Operation not
supported" (3 of 3 runs); now the model loads and the completion of
"The capital of France is" starts with " Paris" (3 of 3 runs).

Takes #6215's framebuffer owners and target-owned sampled textures, keeping this branch's sample-order steps after the framebuffer and the sampled-only usage next to the storage order view.
Some titles stop on a prompt to shake the controller, which keyboard players
and controllers without motion sensors cannot answer. While the Shake input is
held (X by default), the composed pad state reports motion with the
acceleration and angular velocity flipping sign every 50 ms; a controller's own
sensor data is used otherwise.
