# P4a ADDS THREE ALTERNATIVES, and each one is here because this is the only CI job that

# unpacks a push build:
|

|
# * `ObjectSubsystem` reaches the three DirectGLES.ObjectSubsystemControl. entries - the
|
||||||
|
# 0x1fff-vs-0x1ff A/B and the 0x9ff dependency refusal (G12). `ResourceSubsystem` does
|
||||||
|
# NOT match it: the two families are named apart on purpose, because they are different
|
||||||
|
# phases' switches and a filter that merged them would hide one behind the other.
|
||||||
|
# * `TextureParamsWithoutASamplerView` reaches G9's four cases, the scenario ROADMAP.md:20
|
||||||
|
# names by hand. It runs in the ambient lanes, which the label already selects - but this
|
||||||
|
# step is where those cases run against a PUSH library, and G9's whole claim is about the
|
||||||
|
# push path. All four cases are green on the contract commit - including the one D-E3
|
||||||
|
# expected to be red, for the reason the scenario's header records - so this row is green
|
||||||
|
# from the day it lands and goes red only if a reachability path stops syncing texture
|
||||||
|
# parameters at all, which is the coupling ARCHITECTURE.md:100 exists to remove.
|
||||||
|
# * `TextureUploadShape` is RECORDED, not gated (D-D4): it asserts that the two upload-shape
|
||||||
|
# counters could be read and that they agree, and prints the shape for MEASUREMENTS.md. It
|
||||||
|
# is in the filter so that the number is actually collected on every run - an unmeasured
|
||||||
|
# shape is not a recorded one - and because its own assertions can go red.
|

|
# As with the four before them, each alternative is the SHORTEST string that selects only what

# G7's negative controls for P4a: drop one field from each of two descriptor conversions on purpose
|
||||||
|
# and prove the emission-consistency suites say so, NAMING the field.
|
||||||
|
#
|
||||||
|
# WHAT G6 CLAIMS. For every framebuffer configuration, texture object, sampler object and program
|
||||||
|
# the client's emitted MGPFramebufferState / MGPResourceDesc / MGPTextureParams / MGPSamplerDesc /
|
||||||
|
# MGPSamplerView / MGPProgramDesc reproduce EXACTLY the values Espryt's SyncToBackend family reads
|
||||||
|
# from the frontend today, field by field. MG_Test/Pipe/{FramebufferEmit,TextureEmit,SamplerEmit,
|
||||||
|
# ImageEmit,ProgramEmit}Test.cpp are what walk it.
|
||||||
|
#
|
||||||
|
# WHY A CONTROL IS NEEDED AT ALL. Those suites are green on a correct conversion, and they would be
|
||||||
|
# just as green on a conversion they had stopped looking at: a walk that drove no configurations, a
|
||||||
|
# comparison that stopped reading the record, an assertion someone loosened. Green says nothing
|
||||||
|
# about whether a suite can still fail. This script makes each of them fail, for the one reason it
|
||||||
|
# exists to catch, and reports a NON-ZERO ctest THAT NAMES THE DROPPED FIELD as the pass.
|
||||||
|
#
|
||||||
|
# THE TWO BREAKS, one per new conversion family, each a break the COMPILER CANNOT SEE - the struct
|
||||||
|
# still has the member, the record is still its pinned size, the PipeFields.def row still names it
|
||||||
|
# and the generated comparator still compares it. What breaks is the VALUE:
|
||||||
|
#
|
||||||
|
# 1. MGPSurface::Layered stops being copied in MG_Impl/Pipe/FramebufferEmit.h. A layered
|
||||||
|
# attachment travels as a non-layered one, which is the shape that turns a whole-array render
|
||||||
|
# target into slice 0 - and SupportsLayeredImageBinding's rule (DirectGLES.cpp:1992-2013,
|
||||||
|
# D-O) forces `layer` to 0 for a non-layerable target, so the wrong answer is silently
|
||||||
|
# plausible rather than an error. It is also the field with the least other coverage: the
|
||||||
|
# surface's Res, Level and Layer are all still right, so nothing about the ATTACHMENT changes
|
||||||
|
# except the one bit that says how much of the texture it is.
|
||||||
|
# 2. SamplerParameters::borderColorForm stops being copied in MG_Impl/Pipe/SamplerEmit.h. All
|
||||||
|
# four border-colour VALUES still cross; what is lost is which of the three forms
|
||||||
|
# (float / int / uint) they are to be read as, and D-F4 is explicit that the form crosses and
|
||||||
|
# that all four values are compared. The failure it models is IntegerBorderColorScenario's:
|
||||||
|
# an integer border colour read as floats is not an error anywhere, it is just the wrong
|
||||||
|
# colour at the clamped edge of every sampled texture.
|
||||||
|
#
|
||||||
|
# Each patch is applied by REGEX rather than by an exact line, because both headers belong to OTHER
|
||||||
|
# PACKAGES (C.7: FramebufferEmit.h is package B's, SamplerEmit.h is package C's) and their spelling
|
||||||
|
# is theirs to choose: any `<something>.<field> = <expr>;` - or the designated-initializer
|
||||||
|
# `.<field> = <expr>,` - has its right-hand side replaced by a constant. If a header does not
|
||||||
|
# assign its field at all, because the emitter has not landed yet or because the conversion is
|
||||||
|
# spelled some other way, that is exit 2, "could not run", never a pass.
|
||||||
|
#
|
||||||
|
# ON THE P4a CONTRACT TREE THIS SCRIPT EXITS 2 AND SAYS SO. Both headers EXIST there - the contract
|
||||||
|
# commit creates all five emit headers with STUB emitters that return 0 payload bytes (contract-v1
|
||||||
|
# D1) - but neither assigns anything, so there is no field copy to drop. That is the honest report:
|
||||||
|
# a control that "passed" because there was nothing to break would be the worst outcome available.
|
||||||
|
#
|
||||||
|
# WHY IT IS NOT A CI LANE. It rebuilds the library up to four times. It is run by hand, and by the
|
||||||
|
# integrator at the P4a five-part gate (D.3 part 3, beside P2's g7_negative_control.sh and P3a's
|
||||||
|
# p3a_vertex_input_negative_control.sh, both of which keep running unchanged).
|
||||||
|
#
|
||||||
|
# Usage:
|
||||||
|
# scripts/p4a_descriptor_negative_control.sh <build-dir>
|
||||||
|
#
|
||||||
|
# <build-dir> a configured build directory carrying the push-only unit suites (the emission
|
||||||
|
# cases are compiled only under MOBILEGL_PIPE_PUSH)
|
||||||
|
#
|
||||||
|
# RESTORE IS NOT ENOUGH; THE REBUILD IS PART OF THE CONTRACT. Once a header has been patched, EVERY
|
||||||
|
# way out of this script goes through repair(): restore the header, rebuild the library from it, and
|
||||||
|
# re-run the suite to prove the tree really went back. `cp` alone leaves <build-dir> holding a
|
||||||
|
# libMobileGL.so in which the field is hard-wired, `ctest` does not rebuild, and nothing in an exit
|
||||||
|
# status tells a caller to. The path that needs this most is the one that reads "NEGATIVE CONTROL
|
||||||
|
# DID NOT TRIP": an engineer reacts to it by opening the suite and re-running ctest against this
|
||||||
|
# very build directory, and every reading they take there would come from a deliberately corrupted
|
||||||
|
# library. So repair() runs from the EXIT trap as well - a mid-way failure (a patched header that
|
||||||
|
# would not compile, an interrupt) repairs too - and a repair that itself fails downgrades the
|
||||||
|
# verdict to 2. On the exits that happen BEFORE any patch (bad arguments, a missing header, a
|
||||||
|
# missing suite) the tree was never touched and the build directory still holds what the caller
|
||||||
|
# built: there is nothing to restore and nothing to rebuild, and the script says which of the two
|
||||||
|
# situations it is leaving behind.
|
||||||
|
#
|
||||||
|
# Nothing is written into the repository. Logs and the header backups live in
|
||||||
|
# <build-dir>/p4a-g7-logs/, which is inside the build tree and therefore neither committed nor
|
||||||
|
# picked up by `git status`; the paths are printed with every verdict.
|
||||||
|
#
|
||||||
|
# Exit codes: 0 BOTH controls tripped AND named their field;
|
||||||
|
# 1 a control did not answer: a suite stayed green with its field dropped, or it went
|
||||||
|
# red without ever naming the field, so the red cannot be attributed to the drop.
|
||||||
|
# Both are findings about the TEST, not errors in this script - and both leave the
|

|

|
||||||
|
# 2 a control could not be run at all (bad arguments; a header or a field absent on
|
||||||

# TWO THINGS THIS SCRIPT ADDS TO ITS PARENT, AND NOTHING ELSE (BRIEF-P4A.md D-N: "keeps every other
|
||||||
|
# property of its parent verbatim"):
|
||||||
|
#
|
||||||
|
# 1. A PER-REGION SOURCE PATH. The parent's SOURCE_PATH is a single file (:85); the seventeen live
|
||||||
|
# in three. Each row below carries its own path and the extractor reads each file once.
|
||||||
|
# 2. A REGION KIND. [declared deviation, see DEVIATIONS below] Sixteen of the seventeen are
|
||||||
|
# FUNCTIONS. `DepthStencilSamplingReadImpl` is a NAMESPACE (DirectGLES.cpp:8117-8578) - the
|
||||||
|
# brief's D-N table names it as though it were a function, and the parent's extractor, which
|
||||||
|
# finds a definition as the one `<name> (` whose closing paren is followed by `{`, finds ZERO
|
||||||
|
# definitions of it and exits 2 forever. Hashing the whole namespace block is also the
|
||||||
|
# stronger reading of "the D24S8 sampling-emulation CORE": the core is the ~460-line block of
|
||||||
|
# staging, conversion and readback, not any one function inside it.
|
||||||
|
#
|
||||||
|
# Everything else is the parent verbatim, and deliberately so:
|
||||||
|
#
|
||||||
|
# HOW A BODY IS EXTRACTED. The file is masked first - comments, string, char and raw-string
|
||||||
|
# literals are replaced by spaces of the same length, so a brace or a parenthesis inside one can
|
||||||
|
# never be counted - and the DEFINITION is then found as the one occurrence of `<name> (` whose
|
||||||
|
# closing parenthesis is followed (past qualifiers like const/noexcept) by `{`. That is what tells
|
||||||
|
# a definition from a forward declaration and from a call site: a call's `)` is followed by `)`,
|
||||||
|
# `;` or `,`, never by `{`. A NAMESPACE row is found as the one occurrence of `namespace <name>`
|
||||||
|
# followed by `{`. The body is then brace matched in the masked text and hashed from the ORIGINAL
|
||||||
|
# text, so a comment change inside one of these is a difference too - which is deliberate: the
|
||||||
|
# claim is "byte-identical", and a comment that stopped describing what the code does is exactly
|
||||||
|
# the kind of drift a "verbatim move" is supposed to be checked for.
|
||||||
|
#
|
||||||
|
# Exactly one definition must be found per name. Zero or two is exit 2 (could not run), never a
|
||||||
|
# silent pass: a rename this gate could not follow must not read as "nothing moved". Two is the
|
||||||
|
# expected shape of a #if/#else pair that re-spells one of these bodies beside an untouched copy -
|
||||||
|
# a finding, not a limitation, because two ladders drift (ID-11, ID-15).
|
||||||
|
#
|
||||||
|
# A SHARED TEMPLATE OVER AN ACCESSOR INTERFACE IS REJECTED (ID-13, MEASUREMENTS.md:521): it resizes
|
||||||
|
# pull symbols and breaks G1. If a P4a arm needs a variant of one of the seventeen it gets its own
|
||||||
|
# `#if MOBILEGL_PIPE_PUSH` function with its own name and its own pinned sha - the
|
||||||
|
# FlushPendingRangesFrom shape.
|
||||||
|
#
|
||||||
|
# Usage:
|
||||||
|
# scripts/p4a_untouched_regions.sh <ref-a> <ref-b> compare the seventeen at two git refs
|
||||||
|
# scripts/p4a_untouched_regions.sh <ref> print the seventeen shas at one ref (a
|
||||||
|
# baseline capture: ... > p4a-before.sha)
|
||||||
|
# scripts/p4a_untouched_regions.sh --self-test prove the comparison can go red
|
||||||
|
#
|
||||||
|
# stdout is always the sha list - `<sha256> <region>`, one per line, in the fixed order above - so
|
||||||
|
# a baseline capture is a plain redirect. Everything else goes to stderr.
|
||||||
|
#
|
||||||
|
# Both arguments are GIT REFS: the gate is about what landed, so an uncommitted edit is invisible
|
||||||
|
# by design. Use HEAD after committing, which is what D.1 and the CI row do.
|
||||||
|
#
|
||||||
|
# Exit codes: 0 the seventeen are identical at both refs (or a single ref was listed);
|
||||||
|
# 1 at least one moved - the first one in the fixed order is named on stderr;
|
||||||
|
# 2 the gate could not run: a bad ref, a missing file, a name that is not defined
|
||||||
|
# exactly once, or a self-test whose control failed to trip.

# compared "against its pinned 3e298c9a sha", and at P4a's base ref the function DOES
