If a windowoverflow8 happened after changing the SP, the exception handler would look for
the extra save area by looking at the previous frame's SP. This SP would be a garbage value
and could cause the windowoverflow exception to write to invalid memory ares.
Moved the following kconfig options out of the target component:
* ESP32_X_BROWNOUT_* -> esp_system
* ESP32_X_DEBUG_OCDAWARE -> esp_system
* APP_NO_BLOBS -> build type (main kconfig)
Upstream xtensa exception handling will save PS, PC, and a0 registers
together when saving a minimal context. This commit ppdates the xtensa
exception handling to match upstream behavior.
The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h
The following functions are deprecated:
- get_sp()
The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()
The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()
All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.

peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"
As branches/jumps on Xtensa have a maximum range for the destination, it is
unsafe to refer to a label to another compilation unit in a branch/jump instruction.
The labels have been replaced by absolute addresses.
components/os: Move ETS_T1_WDT_INUM, ETS_CACHEERR_INUM and ETS_DPORT_INUM to l5 interrupt
components/os: high level interrupt(5)
components/os: hli_api: meta queue: fix out of bounds access, check for overflow
components/os: hli: don't spill registers, instead save them to a separate region
Level 4 interrupt has a chance of preempting a window overflow or underflow exception.
Therefore it is not possible to use standard context save functions,
as the SP on entry to Level 4 interrupt may be invalid (e.g. in WindowUnderflow4).
Instead, mask window overflows and save the entire general purpose register file,
plus some of the special registers.
Then clear WindowStart, allowing the C handler to execute without spilling the old windows.
On exit from the interrupt handler, do everything in reverse.
components/bt: using high level interrupt in lc
components/os: Add DRAM_ATTR to avoid feature `Allow .bss segment placed in external memory`
components/bt: optimize code structure
components/os: Modify the BT assert process to adapt to coredump and HLI
components/os: Disable exception mode after saving special registers
To store some registers first, avoid stuck due to live lock after disabling exception mode
components/os: using dport instead of AHB in BT to fix live lock
components/bt: Fix hli queue send error
components/bt: Fix CI fail

eh_frame_parser is architecture independent, thus the files have
been rearchitectured. Some bugs have been fixed in the test.
A README file has also been added to eh_frame_parser host test
directory.
eh_frame_parser is now able to detect empty gaps in .eh_frame_hdr
table (missing DWARF information).
Fix a bug occuring when parsing backtraces originated from abort().
Fix build missing dependencies issue.
Add .eh_frame and .eh_frame_hdr sections to the binary (can be
enabled/disabled within menuconfig). These sections are parsed
when a panic occurs. Their DWARF instructions are decoded and
executed at runtime, to retrieve the whole backtrace. This
parser has been tested on both RISC-V and x86 architectures.
This feature needs esptool's merge adjacent ELF sections feature.
Copy the esp32c3 code without any change:
* components/esp_hw_support/include/soc/esp32h2
* components/esp_hw_support/port/esp32h2
* components/esp_system/port/soc/esp32h2
By unchecking "Place panic handler code in IRAM" in the menuconfig,
the panic handlers will be placed in flash. Of course, flash cache must
be activated when entering panic handlers.
