pass synchronous syscall arguments in registers 
rt_syscall_op -> rt_syscall

split the syscall enum between synchronous and asynchronous syscalls

add explicit YIELD syscall enum

split blocking states by sem vs. mutex to simplify donation and timeouts

fix ready list management on c28 2024-03-07 23:57:53 -08:00
Chris Copeland 2bf718b17e
remove PRE- and POST- TASK_CONSTRUCTOR_PRIORITY 
these aren't needed internally anymore, and rust tasks don't use the
same constructor priorities as C tasks, so they may not be respected
anyway

Chris Copeland 82d9af898e
remove RT_SYSCALL_TASK_READY 
have rust's task init add directly to ready lists, which themselves don't need a constructor anymore

Chris Copeland dd5438f39c
split rt_syscall_run into rt_syscall_run and rt_syscall_run_pending 
rt_syscall now triggers a single syscall synchronously, masking the
pending syscall handler

split the svc and syscall irq handlers on arch/arm/ar

split the svcall and pendsv handlers on arch/arm/m

add a user1 interrupt handler on arch/c28

invoke synchronous syscalls directly in the active thread in arch/pthread

move rt_pending_syscalls to privileged .bss now that tasks don't need
to modify it

add alignment attribute to arm/ar interrupt handler macros

provide CPACR_FPU_ENABLE to assembler and initialize task's cpacr to the
processor's default, fpu-disabled, value rather than 0

don't yield for empty rt_pending_syscalls (yield is synchronous only)

add missing sigemptyset to block_all_signals

update arch/arm/README.md
