- Added POSIX desktop support for SDK builds, application packaging, and integration testing. - Added POSIX filesystem partitions and improved application path handling. - Added simulator support for loading and running applications dynamically. - Improved simulator task stack handling and display startup reliability. - Improved simulator display scaling, resizing, high-DPI support, and pointer accuracy. - Fixed LVGL timers and input polling on POSIX. (fixes simulator with Linux on some Intel graphics platforms) - Standardized data paths across platforms. - Logging now works via separate task: this allows apps to write to log without it affecting their stdout (for apps that output text as relevant date for other apps, like the File Selection app) - Fixes for app stdio

/**
|
|
* Linked in with -Wl,--wrap=pthread_attr_setstack (see Tactility/CMakeLists.txt).
|
|
*
|
|
* FreeRTOS's POSIX port (Libraries/FreeRTOS-Kernel/portable/ThirdParty/GCC/Posix/port.c)
|
|
* hands every task a stack carved out of its own heap (pvPortMalloc) via this call.
|
|
* pthread_attr_setstack requires page alignment, which pvPortMalloc doesn't guarantee;
|
|
* when it happens to succeed anyway (allocator alignment can vary run to run), the
|
|
* task's real pthread stack ends up living inside that small FreeRTOS heap region -
|
|
* fine for typical embedded task code, but a desktop GL driver doing on-the-fly shader
|
|
* compilation on that thread (e.g. Mesa on first frame present) can overflow it and
|
|
* silently corrupt adjacent heap_4 objects.
|
|
*
|
|
* Wrapping the call out entirely (rather than patching the vendored port.c) leaves every
|
|
* task's pthread_attr_t at its pthread_attr_init() default, so pthread_create() always
|
|
* gives it a real, properly allocated default-size stack instead.
