ThreadX still declares 6.5.1.202602 with hotfix 'a', which is the previous
release rather than the one being cut.
prepare_release.sh updated the five version constants in tx_api.h and the
version string in 211 port headers across ports, ports_smp, ports_arch and
ports_module. The hotfix letter is cleared, since the target has none. Nothing
else changed: every line in the port commit carries a version, and no file
outside an inc/tx_port.h was touched.
The port consistency checks passed before the branch was cut, which is what the
script gates on. Host regression 113/113 with zero warnings, and the AI
disclosure check passes.

The per-edit disclosure named the product and model, so every agent and every
model version appended another line. 74 files carried two to four of them, and
the same five products had accumulated 13 spellings -- Copilot against GitHub
Copilot, Claude Sonnet 4.6 against claude-sonnet-4.6, four spellings of Codex.
Twenty assembly lines carried a doubled comment marker, `; //` or `@ //`.
Every file now carries exactly one line, fixed text naming no product:
Portions of this file were generated with AI assistance.
It is written with the comment character that file already uses, so the `;`
and `@` assembly files keep theirs and the doubled markers are gone. Precise
attribution stays on the commit, where the Assisted-by trailer is per-change,
dated and attached to the diff it describes. A header line cannot hold that
record honestly, because the code it names gets rewritten and the line stays.
A file-level flag answers whether; the history answers who.
Comment-only. 455 files, 455 insertions and 574 deletions: every removed line
was a disclosure line, every added line is the fixed text, and no file is left
with zero or with more than one. `scripts/check_ports.sh` passes, including the
reproducibility check that would catch a ports_arch master and its generated
copies drifting apart. Recompiled against dev, every file that builds without a
vendor toolchain gives a byte-identical object: 19 of 19 C files under common,
100 of 100 GNU assembly files, and all 16 assemblable files whose comment
marker changed. The 10 remaining marker changes are ac5 and IAR sources where
`;` already started the comment and only the redundant `//` was removed.

The Arm Development Studio launch configurations and the IAR project files
carried absolute paths from the machines they were last opened on: four
individuals' home directories, a Broadcom support build tree, and directories
such as C:\release\threadx, C:\temp1702\tx and D:\threadx. They are published in
the repository and none of them resolves for anyone else.
In the launch files all of it is saved session state, which files that were never
opened in a debugger simply do not have:
breakpoints 72 files, saved breakpoints anchored to source
paths under cortex_a35 on one machine. Emptied
rather than deleted, matching the 27 launch files
that already carry an empty list.
scripts_view_script_links 70 files, a scripts view cache. The script the
launch actually runs is named one line earlier
through ${workspace_loc:...}, which is portable.
substitutePath 65 files, source lookup remapping. 30 map a path
to itself, and the rest point at one machine's
copy of libgloss or a build directory.
TREE_NODE_PROPERTIES 39 files, which rows the variables view had
expanded.
DebugCommandLine.History 2 files, the debug console command history,
including a typed absolute path.
The two IAR cases are not session state and are corrected rather than removed:
IarchiveOutput 23 files. The librarian output path pointed at
another machine, so the library was written
outside the project. Set to ###Unitialized###,
which 86 other option blocks already use, letting
IAR derive $EXE_DIR$\$PROJ_FNAME$.a.
IlinkIcfFile 1 file. The linker configuration file is load
bearing, so the file name is kept and the path
made project relative, as 33 other option blocks
spell it.
Seven of the files are ports_arch templates, so the generators would otherwise
have copied the paths back.
Verified: all 162 launch and IAR project files in the tree parse as well-formed
XML afterwards, no tracked launch or project file mentions any of the four user
names, and scripts/check_ports.sh passes, so the templates and their generated
copies still agree.

Two identifiers in the Arm Development Studio launch configurations still said
A35 in every AArch64 port, because the generator's patch table could not reach
them.
The config database taxonomy id is spelt in lower case in the launch files,
/platform/armfvp/base_a35x4, but the search string read base_A35x4. Both
generators are case sensitive here, sed in update.sh and -creplace in
update.ps1, so the rule matched nothing and all 27 ports kept the A35 taxonomy
id while the platform name and model beside it named the right core. That the
rule exists at all shows the substitution was intended, and the ARMv7-A
generator does the same thing correctly, which is why its ports carry a per-core
ve_cortex_a<n>x1 id.
The SMP launch files name the activity "Cortex-A35x4 SMP" where the ThreadX ones
say "Debug Cortex-A35", so the existing activity rule reached the ThreadX ports
only and every SMP port advertised an A35 activity. Add a rule that matches the
" SMP" suffix, which also keeps it from rewriting the FVP model name that the
line above already handles.
Both changes are mirrored in update.ps1, which stays equivalent to update.sh.
Verified by regenerating: 50 launch files change and nothing else, 100 lines of
taxonomy id across 24 ThreadX and 26 SMP files, and 52 lines of activity name
across the 26 SMP files. No other attribute in those files moves, so the new
" SMP" rule does not touch the model name. The two Cortex-A35 ports are
untouched, as they must be, since substituting A35 for A35 is a no-op.
scripts/check_ports.sh passes, so the result is reproducible.
This cannot be exercised here: confirming that Arm Development Studio resolves
the per-core taxonomy ids needs Arm Development Studio. The change rests on the
platform name and model already naming the core, on the patch rule's existence,
and on the ARMv7-A ports having shipped per-core ids all along.

ports/cortex_a34, ports_smp/cortex_a34_smp and ports_smp/cortex_a78_smp were
absent from the ARMv8-A generator's core list, so ports_arch never reached them
and scripts/check_ports.sh could not detect that they had drifted. They had.
The two Cortex-A34 ports sat two releases behind the shared sources, at 6.1.10
against 6.3.0. The difference is not only banners: tx_initialize_low_level.S
lacked the SUB x1, x1, #15 that precedes the BIC when the system stack pointer
is recorded, so the value stored was the incoming SP rather than the first
16-byte boundary below it. The Arm Development Studio example was missing
GICv3_aliases.h, which every other port's GICv3_gicc.h includes to reach the
interrupt controller registers through the stringify indirection.
The Cortex-A78 SMP port had never had its debug launch configuration patched at
all. It still named the A35 platform and model, so Debug Cortex-A35,
Base_A35x4 and FVP_Base_Cortex-A35x4 would have started an A35 model for an A78
port.
Add cortex_a34 to the core list. Cortex-A78 cannot go in the same list, because
the generator walks cores against port sets and would then create a
ports/cortex_a78 that the tree has never had; give it a separate SMP-only list
consulted only for the tx_smp port set. Both changes are mirrored in update.ps1,
which stays equivalent to update.sh.
Verified by regenerating: exactly these three port directories change, 116 files
modified and 13 added, and no already-covered core moves, so the core list was
the only thing holding them back. scripts/check_ports.sh passes, which now means
these three are checked for reproducibility for the first time.
scripts/check_clang.sh reports 38 of 38 example builds linked, the three new
ports included.
readme_threadx.txt is not added here. Only the two Cortex-A35 template ports
carry it; the other 23 AArch64 ports do not, so its absence from Cortex-A34 is
the tree's norm rather than drift, and supplying it everywhere is separate work.

Follow up on the issue-541 execution profiling work. PR #553 fixed SMP execution profile total-time aggregation, and PR #554 fixed Armv7/R SMP timestamp hooks that used decrementing private timers.
This change addresses the remaining related gap in ARMv8-A SMP ports: their timestamp hooks returned zero, which left execution profiling and trace timestamps without a progressing time source. Replace those stubs with the architectural generic physical counter, CNTPCT_EL0, across the ARMv8-A SMP GNU, AC6, IAR, and GHS variants.
The local ARMv8 AArch64 system timer example already uses CNTPCT_EL0 for physical count reads, so this keeps the SMP timestamp hook aligned with the existing port examples while preserving the 32-bit ULONG return contract.
