Route legacy PAwR peripheral completion events through the active periodic
sync callback and accept the controller-established link without normal
advertising state.
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.
