Tick hook registration lives in esp_system, so its scheduler-suspension
coverage belongs in the esp_system unity test app rather than the
freertos IDF additions suite.
Extends esp_backtrace_print_all_tasks() to RISC-V targets. For running
tasks, registers are captured using UNW_GET_CONTEXT(); for suspended
tasks, the saved RvExcFrame on the task stack is used. Dual-core support
follows the same IPC pattern as the Xtensa implementation.
Backtrace output adapts to the configured backtrace method:
EH-frame, frame-pointer, or register dump (with a hint to enable
frame-pointer mode).
On RISC-V chips with SPIRAM support (esp32c5, esp32c61, esp32h4, esp32p4,
esp32s31), esp_restart_noos() was disabling the cache while the current
stack pointer could still be in external RAM. Any stack access after cache
disable (function call, local variable spill) would then fault with
"Cache disabled but cached memory region accessed".
Xtensa chips (esp32, esp32s2, esp32s3) already had this guard via the
SET_STACK macro. Add the equivalent for RISC-V:
- Add rv_utils_set_sp() to riscv/rv_utils.h (plain "mv sp, %0" with a
memory clobber; no window register management needed on RISC-V)
- In each affected system_internal.c, under
CONFIG_FREERTOS_TASK_CREATE_ALLOW_EXT_MEM, check whether the current
SP is in PSRAM and if so switch it to the top of internal BSS before
any cache disable or writeback operation
- Fix xTaskCreateStaticPinnedToCore() stack size argument in the
spiram_stack test (was passing bytes instead of word count)
- Mark the null-pointer write in func_do_exception() as volatile to
prevent the compiler from optimizing it away
- Extend the [spiram_stack] tests to RISC-V by sharing fibonacci() and
the task/finish helpers across architectures, guarding only the
Xtensa-specific WINDOWBASE/WINDOWSTART prints
- Removed conditional definitions for various RCC_ATOMIC macros across
multiple files, replacing them with a unified PERIPH_RCC_ATOMIC() macro.
- Updated instances where specific RCC_ATOMIC macros were used to ensure
consistent usage of PERIPH_RCC_ATOMIC().
- Deleted unused uart_share_hw_ctrl.h file as its functionality is now
integrated into the new structure.
esp_stdio contains everything the old esp_vfs_console contained (the vfs stdio glue layer)
as well as other functionality related to stdio (previously referred to as console)
Removed
- target markers. Now must use target as parametrization in esp-idf
- host test markers. Now will be automatically added with linux target and qemu marker
This commit renames all registers in xtensa/specreg.h to by adding the
prefix XT_REG_. This is done to avoid naming collisions with similar
variable names. A new register file, viz., xt_specreg.h is created. The
previous names are still available to use but have been deprecated.
