config SIM_M32 |
|
bool "Build 32-bit simulation on 64-bit machine" |
|
default n |
|
---help--- |
|
Simulation context switching is based on logic like setjmp and longjmp. This |
|
context switching is only available for 32-bit targets. On 64-bit machines, |
|
this context switching will fail. |
|
|
|
The workaround on 64-bit machines for now is to build for a 32-bit target on the |
|
64-bit machine. The workaround for this issue has been included in NuttX 6.15 and |
|
beyond. For thoses versions, you must add SIM_M32=y to the .config file in |
|
order to enable building a 32-bit image on a 64-bit platform. |

|
config SIM_WALLTIME |
|
bool "Execution simulation in near real-time" |
|
default n |
|
---help--- |
|
NOTE: In order to facility fast testing, the sim target's IDLE loop, by default, |
|
calls the system timer "interrupt handler" as fast as possible. As a result, there |
|
really are no noticeable delays when a task sleeps. However, the task really does |
|
sleep -- but the time scale is wrong. If you want behavior that is closer to |
|
normal timing, then you can define CONFIG_SIM_WALLTIME=y in your configuration |
|
file. This configuration setting will cause the sim target's IDLE loop to delay |
|
on each call so that the system "timer interrupt" is called at a rate approximately |
|
correct for the system timer tick rate. With this definition in the configuration, |
|
sleep() behavior is more or less normal. |

Pixel depth in bits. Valid choices are 4, 8, 16, 24, or 32. |

If you use the X11 display emulation, the selected BPP must match the BPP |
|
of your graphics hardware (probably 32 bits). Default: 8 |
