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.
Expose RC_FAST as a shared MCPWM group clock source for timers,
capture timers, and carriers on ESP32-C5, ESP32-C6, ESP32-H2,
and ESP32-P4. Fix the ESP32-S31 MCPWM clock selector mapping.
Add a hardware runtime test that verifies MCPWM Timer counting
resolution for every supported clock source.
Add SOC_DEBUG_HAVE_OCD_STUB_BINS for esp32c5, esp32c61, esp32h4,
esp32h21, esp32p4, and esp32s31. Update TEE linker scripts with
correct esp_tee_app_config offsets for the 0x3000 stub reservation
The Key Manager hardware peripheral in its current form needs further
design changes before it can be offered as a production feature.
Until a revised peripheral design is available, withdraw ESP-IDF
support for it on all Key Manager capable targets.
Add USB DFU and OTG console SOC capability flags for esp32s2, esp32s3, and esp32p4.
Use these caps in Kconfig, documentation conditionals, and idf.py DFU actions so USB support
is derived from SOC capabilities instead of hardcoded target names.
- add ESP32-S31 debug probe LL, target IDs, capability macros, and GPIO signal mapping
- allow LP probe channels to configure four signal bytes while keeping 16 GPIO outputs
- add HP and LP probe read tests, including LP 32-bit read verification
- keep existing vbat LP probe usage aligned with the new LP channel behavior
feat(security): Add support for the ESP32-P4 Permission Control (PMS) peripheral
Closes IDF-9997, IDF-13529, IDF-13737, and IDF-14381
See merge request espressif/esp-idf!44205
Add LP SPI HAL LL layer for ESP32-S31 and ESP32-P4, enable the
peripheral in soc_caps, and port the HP-side and LP-core-side SPI
drivers to use the new LL abstraction.
