modem retention: Support esp32c6 wifi MAC and baseband sleep retention sleep_modem: wifi MAC modem wakeup protect in modem state before PMU trigger sleep enable request sleep modem: provide a interface to get whether the Modem power domain is allowed to power off during sleep add i2c_ana master header file to project auto beacon: release PMU's lock on root clock source (it is locked in the PLL) wifi receiving beacon frame in PMU modem state strongly depends on the BBPLL clock, PMU will forcibly lock the root clock source as PLL, when the root clock source of the software system is selected as PLL, we need to release the root clock source locking. When it is judged that the PLL is locked by PMU after wakeing up from the PMU modem state, switch the root clock source to the PLL in the sleep process (a critical section). auto beacon: fix the failure to receive broadcast/multicast frames in modem state When the multicast field in the beacon frame received in the PMU modem state is True, the PMU switches to the PMU active state (the PMU waits for the HP LDO to stabilize and then restores the MAC context) and starts to receive broadcast/multicast frames (Broadcast/Multicast frames will be sent after a minimum delay of 48 us after the beacon frame), because the PMU waits for the HP LDO to stabilize too long (~154 us), which will cause broadcast/multicast frame reception to be missed. auto beacon: select the PLL clock source as the REGDMA backup clock source when the PMU switches to ACTIVE from MODEM state update Digital Peripheral (M2A switch) REGDMA restore time parameter auto beacon: fix the issue that only channel 1 can connect to AP in modem state
esp_hw_support (G1 component)
This component contains hardware-related operations for supporting the system. These operations are one level above that of hal in that:
- it uses system services such as memory allocation, logging, scheduling
- it may be multi-step operations involving/affecting multiple parts of the SoC
- it offers a service for other components vary from multiple layers (G1, G2 and G3) of ESP-IDF
Implementations that don't fit other components cleanly, but are not worth creating a new component for (yet) may also be placed here as long as they don't pull dependencies other than the core system components.
Event-Task Service (esp_etm)
esp_etm driver design
esp_etm driver is divided into two parts:
- The core driver, which focuses on ETM channel allocation and offers APIs to connect the channel with ETM tasks and ETM events that come from other peripherals.
- Peripheral side extensions, e.g. GPTimer support generating different kinds of ETM events, and accept multiple ETM tasks. These extensions are implemented in the peripheral driver, and can be located in different components. Usually, the task and event extensions will simply inherit the interface that defined in the core driver.
See the following class diagram, we take the GPIO and GPTimer as the example to illustrate the architecture of esp_etm driver.
