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.
A dispatch over maxComputeWorkGroupCount was split into vkCmdDispatchBase
chunks whose base reached the limit, which VUID-vkCmdDispatchBase-baseGroupX-00421
forbids, and NVIDIA refused the split outright.
Compute modules now declare WorkgroupOffset specialization constants (default 0)
that the recompiler adds to WorkgroupId and GlobalInvocationId and keeps
unmaterialized. Each chunk is recorded with vkCmdDispatch from group 0, bound to
a pipeline variant specialized with the chunk's base. The NVIDIA throw is gone;
device-memory LDS splits still throw.
Fixes#7375
Imports, type-3 mirrors and the buffers and textures placed in host memory share the driver's system memory heap. On Windows that heap is half the physical memory, so on a 16 GiB machine the old budget (the heap less 2 GiB) let imports hold about 6 of its 8 GiB, and host buffer allocations then overflowed into the 256 MiB device-local host-visible heap and failed. The budget now reserves the larger of 2 GiB and half the largest host heap.

Resolves the shader debt file bullet by bullet: main's EmitSetAttribute entry, and this branch's PERSP_SAMPLE/LINEAR_SAMPLE and pixel-position entries.
Repacked copies and depth stencil copies allocated device-local memory
directly and stopped the title on a refusal; they now take the same
allocation path as the other images. Device buffers choose their host
fallback type the same way, the host placement line carries the cumulative
MiB, and the debt file records that a placed image stays in host memory
for its lifetime.
A queue that delivered an end-of-pipe interrupt from its own release stopped
delivering the flip's event for the rest of the run, so a title that raises a
release interrupt once and then waits on the flip event never saw it again.
Count the flips a queue has taken since its last delivered release interrupt:
four consecutive flips keep the latch, a fifth clears it and raises the event,
so the queue recovers within five flips. Gran Turismo 7 (PPSA01317) pairs two
flips with one release interrupt per frame, which stays under the limit, and a
title that flips without further release interrupts recovers.
Extend agc_driver_eop_interrupts: a latched queue still delivers its own
releases, flips keep reaching the video output while their event is suppressed,
an event returns once the latch clears, and a release followed by two flips
raises none.
ARCHITECTURE.md and the libSceAgcDriver debt entry now say that a
settled Windows import under 1 MiB returns to the write watch only when
no storage image overlaps it, and why.
