ldgen skips regeneration when a fingerprint over the section names, the
linker fragment files, sdkconfig and Kconfig is unchanged. The linker
script template was not part of that fingerprint, even though everything
outside its mapping placeholders is copied into the generated script
verbatim.
The build system regenerates the preprocessed template whenever any of
its inputs changes, not only when a linker fragment changes. When such a
change reaches ldgen but leaves the section names alone, the fingerprint
still matches, generation is skipped, and the image is linked against the
previously generated script. The skip path updates the mtime of the
output, so nothing in the build output shows that the change was dropped.
Add the template to the fingerprint so that regenerating it always
regenerates the linker script.

Route legacy PAwR peripheral completion events through the active periodic
sync callback and accept the controller-established link without normal
advertising state.
Accept spec-legal NAN availability time bitmaps (period > 512 TU,
bitmap length > 4, full 9-bit start offset) so iPhone secured NDP
setup is no longer rejected with NDL_UNACCEPTABLE.
Fixes NAN NDP interop with the iPhone 17 series.
iPhone (and hostap) set Key Type=0 in the pairing NIK follow-up Shared-Key
Descriptor (key_info=0x1340) since the NIK is not a pairwise key. We required
the pairwise bit and rejected the frame before decryption, so the NIK
exchange timed out and pairing was torn down. Require only the Encrypted
Key Data bit.
The critical section port already disables interrupts and reads the core id for
the whole section, but spinlock_acquire()/spinlock_release() then disabled
interrupts again to the same level and re-read the core id register.
Add spinlock_acquire_impl()/spinlock_release_impl(), which take a caller-supplied
owner id and skip interrupt management, and reuse them from
spinlock_acquire()/spinlock_release() to avoid duplicated code. The Xtensa and
RISC-V ports now read the core id once and call the impl variants, removing one
core id read and one interrupt mask/restore per critical section enter and exit.

Trim bootloader size by moving some logs to DEBUG. Allows
compiling bootloader on P4 with CONFIG_ESPTOOLPY_FLASHMODE_QIO
without changing partition table offset
ESP32-S31 uses the same trace encoder IP as ESP32-P4. Of the E-Trace v2.0
parameters the two targets report, only privilege_width_p differs (1 on P4,
2 on S31), and it affects both the sync packet layout and the filter's
privilege selector.
- Add the SOC_RISCV_TRACE_* caps for ESP32-S31 along with the esp32s31 LL, and
declare TRACE0/TRACE1 in the target's trace_struct.h.
- Carry privilege_width_p as SOC_RISCV_TRACE_PRIV_WIDTH so the sync packet
decoder can locate the address field, which starts one bit later on targets
that implement supervisor mode.
- Use the RISC-V architectural privilege encoding (0 user, 1 supervisor,
3 machine) in the public filter enum so the values do not change per target,
and let each LL narrow them to its own register field.
- Add riscv_trace_ll_priv_is_supported() per target, so a privilege level the
selector cannot represent is rejected with ESP_ERR_NOT_SUPPORTED rather than
being silently narrowed to a different level. It lives next to the narrowing
code so the two cannot drift apart.
- Fix trace buffer allocation on targets whose internal RAM is not reached
through a cache. esp_cache_get_alignment() reports 0 there, which underflowed
the size check and failed every allocation. Align base and size to the larger
of the reported cache line and the encoder's 4-byte write granularity.
The cxx component re-injects its own archive late on the link line so its
stack-unwind wrappers take precedence over libgcc's (when C++ exceptions
are disabled). It does this through an INTERFACE helper, libgcc_cxx, that
carries `$<TARGET_FILE:${cxx}>`. That helper was linked back into the cxx
target with PUBLIC, which places it in the cxx archive's own
LINK_LIBRARIES, so the cxx target ends up transitively referencing its
own output file.
When CMake computes the cxx target's sources it walks the target's own
link implementation, encounters `$<TARGET_FILE:${cxx}>`, and to resolve the
file it needs the target's link language, which in turn needs its
sources. This loop makes generation fail with:
The SOURCES of "..." use a generator expression that depends on the
SOURCES themselves.
CMake only hits this when it reaches the cxx target standalone before the
target has been pulled into a link by a consumer, and whether that
happens depends on the project layout and target evaluation order. That
is why it surfaces only in some projects, while the examples build fine.
Link libgcc_cxx as INTERFACE instead of PUBLIC. A static archive is not
linked, so its private LINK_LIBRARIES are inert; consumers still receive
libgcc_cxx through INTERFACE_LINK_LIBRARIES, so the intended link order is
preserved. Removing the self-reference makes generation independent of
evaluation order.

On some Windows systems, antivirus, endpoint-security or DLP/encryption
software intercepts short-lived toolchain processes and strips their
stdout when the build captures it through a pipe, while the same command
prints its output normally when run by hand. The tool exits successfully
but returns nothing, and each build step that reads toolchain output then
failed with a different, cryptic error far from the real cause:
- CMake configuration aborted with "Unknown arguments specified" in
components/xtensa/project_include.cmake, or "check_expected_tool_version
invoked with incorrect arguments" in components/esp_common.
- ldgen turned the empty objdump output into an opaque pyparsing
"Expected 'In archive'" traceback.
- idf_tools.py silently reported the compiler/debugger version as
"unknown", sending users into a fruitless reinstall loop.
Detect the empty result at each consumer and fail (or warn) with an
actionable message that names the likely cause and the remedy:
- tools/cmake/compiler_query.cmake: new __compiler_query() helper runs a
compiler query and fails with a clear error on empty or failed output.
It is a standalone module included by both the cmakev1 and cmakev2
utilities, since the esp_common and xtensa project_include.cmake that
call it are shared by both build systems. The xtensa if() arguments are
now quoted so an empty result no longer collapses into a parse error.
- tools/ldgen/ldgen.py: _run_objdump() rejects empty objdump output, and
non-empty-but-unparsable section info is caught and re-raised as a clear
LdGenFailure instead of a raw pyparsing traceback.
- tools/idf_tools.py: empty version output now warns with the cause and
returns UNKNOWN_VERSION instead of silently reporting "unknown".

Skip processing cxx/project_include.cmake when building subprojects such
as ULP as they use custom toolchain and IDF toolchain helpers are not
available.
