If the virtual-address pool is exhausted when reserving the unencrypted PSRAM carve-out (the warning at L388 may already have fired for the main mapping), esp_mmu_map_reserve_block_with_caps() returns an error rather than aborting. Convert the previous assert() into a logged fallback that disables the carve-out for this boot, mirroring the SPIRAM_ENC_EXEMPT_SIZE >= psram_available_size path. Also extend esp_psram_extram_test() to run the standard memory test on the carve-out region when CONFIG_SPIRAM_ENC_EXEMPT is enabled, so the unencrypted mapping is exercised on startup like the other PSRAM regions.
PSRAM MSPI Interrupt Handling
Overview
This file (system_layer/esp_psram_mspi.c) handles PSRAM-specific MSPI interrupt registration.
| Chip Type | MSPI_LL_INTR_SHARED |
Behavior |
|---|---|---|
| Shared IRQ | 1 | Register to shared MSPI dispatcher |
| Separate IRQ | 0 | Register standalone PSRAM ISR via esp_intr_alloc() |
