There was race condition where interrupt entries set by APP cpu core
could have been cleared during PRO cpu startup.
This was observed while setting up "cache access error" interrupt in
SMP mode for ESP32-S3.
This fix allows to NOT modify or clear any entries set by other core
(APP or PRO) and thus avoiding any race conditions during startup code.
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The labels have been replaced by absolute addresses.
Clang warns that the original code wouldn't have any effect:
warning: indirection of non-volatile null pointer will be deleted,
not trap [-Wnull-dereference]
note: consider using __builtin_trap() or qualifying pointer
with 'volatile'
__builtin_trap translates to 'break 1, 15' instruction on Xtensa,
which might be okay in this case. However to absolutely certainly not
break anything for GCC builds, add 'volatile' instead.
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

PMS aware chips require prefetch padding size for instruction fetch, or
some memory alignment considerations. These settings are now exposed
through kconfig options (hidden) and used through common ld template.
This shall help to add and manage future chips support easily for
these considerations.
Closes IDF-3624
Add Kconfig option SPIRAM_ALLOW_NOINIT_EXTERNAL_MEMORY
When enabled, a new linker script rule (from esp32.extram.noinit.ld)
places any variables in the .ext_ram.noinit section in SPIRAM.
This section is exempted from the startup SPIRAM memory test and is
not zero-initialized or added to the malloc pool, making it usable
for noinit variables that persist across reset.
The EXT_RAM_NOINIT_ATTR macro places variables in this section.
IRAM section didn't contain sufficient padding for possible CPU instruction prefetch,
ie instruction fetch could happen in DRAM section which is prohibited by the Memprot module.
This is fixed by adding 16B to the end of IRAM section in LD script (C3 CPU prefetch buffer depth is 4 words)
Closes IDF-3554
* fix
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
This is mostly important on ESP32 ECO3 with the
ESP32_ECO3_CACHE_LOCK_FIX, because when we stall the other CPU core
before we disable the TG1 WDT then the first CPU can get stuck
in WDT ISR handle_livelock_int routine waiting for the other CPU.
* This function has been accidentally removed.
It is necessary to provide the emergency
exception memory pool size for C++ code.
Since our libstdc++ always has exceptions
enabled, this function must exist here even if
-fno-exception is set for user code.
