| config SIMULATOR_XTENSA |
| bool "Simulator Configuration" |
| help |
| Specify if the board configuration should be treated as a simulator. |
| |
| config SYS_CLOCK_HW_CYCLES_PER_SEC |
| prompt "Hardware clock cycles per second, 2000000 for ISS" |
| default 2000000 |
| range 1000000 1000000000 |
| help |
| This option specifies hardware clock. |
| |
| config XTENSA_NO_IPC |
| bool "Core has no IPC support" |
| select ATOMIC_OPERATIONS_C |
| help |
| Uncheck this if your core does not implement "SCOMPARE1" register and "s32c1i" |
| instruction. |
| |
| config XTENSA_RESET_VECTOR |
| bool "Build reset vector code" |
| default y |
| help |
| This option controls whether the initial reset vector code is built. |
| This is always needed for the simulator. Real boards may already |
| implement this in boot ROM. |
| |
| config XTENSA_USE_CORE_CRT1 |
| bool "Use crt1.S from core" |
| default y |
| help |
| SoC or boards might define their own __start by setting this setting |
| to false. |
| |
| config XTENSA_ENABLE_BACKTRACE |
| bool "Backtrace on panic exception" |
| default y |
| depends on SOC_ESP32 || SOC_FAMILY_INTEL_ADSP |
| help |
| Enable this config option to print backtrace on panic exception |
| |
| config XTENSA_CPU_IDLE_SPIN |
| bool "Use busy loop for k_cpu_idle" |
| help |
| Use a spin loop instead of WAITI for the CPU idle state. |
| |
| config XTENSA_WAITI_BUG |
| bool "Workaround sequence for WAITI bug on LX6" |
| help |
| SOF traditionally contains this workaround on its ADSP |
| platforms which prefixes a WAITI entry with 128 NOP |
| instructions followed by an ISYNC and EXTW. |
| |
| config XTENSA_SMALL_VECTOR_TABLE_ENTRY |
| bool "Workaround for small vector table entries" |
| help |
| This option enables a small indirection to bypass the size |
| constraint of the vector table entry and moved the default |
| handlers to the end of vector table, renaming them to |
| _Level\LVL\()VectorHelper. |
| |
| config XTENSA_RPO_CACHE |
| bool "Cached/uncached RPO mapping" |
| help |
| Support Cached/uncached RPO mapping. |
| |
| A design trick on multi-core hardware is to map memory twice |
| so that it can be seen in both (incoherent) cached mappings |
| and a coherent "shared" area. |
| |
| if XTENSA_RPO_CACHE |
| config XTENSA_CACHED_REGION |
| int "Cached RPO mapping" |
| range 0 7 |
| help |
| This specifies which 512M region (0-7, as defined by the Xtensa |
| Region Protection Option) contains the "cached" mapping. |
| |
| config XTENSA_UNCACHED_REGION |
| int "Uncached RPO mapping" |
| range 0 7 |
| help |
| As for XTENSA_CACHED_REGION, this specifies which 512M |
| region (0-7) contains the "uncached" mapping. |

| config XTENSA_CCOUNT_HZ |
| int "CCOUNT cycle rate" |
| default 1000000 |
| help |
| Rate in HZ of the Xtensa core as measured by the value of |
| the CCOUNT register. |
