Before:
The cache won't be disabled when XIP on psram. But during flash
erasing/programming, read data will be courrupt.
When XIP in psram is enabled, the image is not mapped to the cache so
usually there will be no flash access. The only way to read from flash
is via the driver or use mmap. The driver has protection during erasing,
while th mmap region not.
Now:
Mmap APIs provide a flag to make mmap->unmap region mutually exclusive
to flash erase/programming when XIP from psram. SPI Flash write APIs
will benefit from this. When the flag is used, no concurrent access to
mapped region will happen while writing; otherwise the cache will be
disable to avoid data corruption.
Most ESP-IDF APIs calls mmap with this flag. As for users calling
mmap-like APIs directly, they can choose whether to enable this by a
flag.
Closes https://github.com/espressif/esp-idf/issues/14897
- Fixed read remote feature timeout when using coded phy
- Fixed disconnection issue(0x08) when using 125k coded phy
- Fixed disconnection issue(0x08) when updating connection param
- Fixed disconnection issue(0x08) when using multi connection
- Avoid error when adding duplicate device to whitelist
- Support disable channel assessment by vendor hci
- Support smaller connection interval (3.75 ms)
- Support duplicate exception list in EVT ADV
Add Kconfig options for bandwidth-optimized logging via the BLE Log
Async Output system. When enabled, controller log levels default to 2
and host/mesh log encoding is auto-selected.
- BT_LOG_CRITICAL_ONLY parent: selects BLE_LOG_ENABLED + compression
- BT_LOG_CRITICAL_ONLY_CTRL: supports both NimBLE and non-NimBLE (C3)
controllers with default level override
- BT_LOG_CRITICAL_ONLY_HOST: host-agnostic, selects compressed log
for Bluedroid conditionally
- BT_LOG_CRITICAL_ONLY_MESH: placeholder for mesh log encoding
- Guards against BT_STACK_NO_LOG conflict
- Fixed enhanced TX power setting and getting for legacy adv
- Fixed BLE assert lld_con.c 2387
- Fixed compatibility issues during the encryption procedure
- Support BLE vendor hci enable CCA command
- Fixed BLE vendor HCI set and get tx power
- Support BLE vendor HCI set adv aux offset command
- Support BLE vendor HCI set CSA support command
- Added config for BLE instant passed workaround
- Fixed btdm_sleep_clock_sync timeout workaround
1. rename linker files
2. support memory release in case that ESP_ALLOW_BSS_SEG_EXTERNAL_MEMORY is enabled
3. improve the implementation of memory release
