AutoClockDown idle loop

During module_start, SceLowio will call SceThreadmgrForDriver_B4A05763 to register an optimized idle loop that performs automatic clock-down of ARM when unused.

This loop uses the AutoClockDown idle context from SceSysmem.

Functionally, the new idle loop behaves as follows:

while (1) {
  __disable_irq(); /* cpsid i */

  /* mark this core as inactive */  
  uint32_t num_active_cores = atomic_sub_32(&SceSysrootForDriver_4B8C305A->num_active_cores, 1);
  if (num_active_cores == 0) {
    /* No more active ARM cores: clock down ARM to 21MHz */
    SceSysrootForDriver_4B8C305A->arm_baseclk_config[0] = ScePervasiveBaseClock[0];
    SceSysrootForDriver_4B8C305A->arm_baseclk_config[1] = ScePervasiveBaseClock[1];

    ScePervasiveBaseClock[0] = 7;
    ScePervasiveBaseClock[0] = 1;
    ScePervasiveBaseClock[1] = 8;

    /* Set num_active_cores to -1, such that the first core to wake up
     * will increment to 0 and realize it needs to restore ARM clocks.
     */
  }

  __wfi(); /* Wait For Interrupt */

  while (SceSysrootForDriver_4B8C305A->num_active_cores == 0) {
     /* Another core is restoring clocks - wait for it.
      * Note that this check is actually integrated in the
      * atomic_add_32 below, so there's no race condition.
      */
  }

  num_active_cores = atomic_add_32(&SceSysrootForDriver_4B8C305A->num_active_cores, 1);
  if (num_active_cores == 0) {
    /* We are the first core to wake up after clock down - restore full speed */
    ScePervasiveBaseClock[0] = 7;
    ScePervasiveBaseClock[1] = SceSysrootForDriver_4B8C305A->arm_baseclk_config[1];
    ScePervasiveBaseClock[0] = SceSysrootForDriver_4B8C305A->arm_baseclk_config[0];
    /* Free all other cores */
    SceSysrootForDriver_4B8C305A->num_active_cores = 1;
  }
  
  __enable_irq(); /* cpsie i */
  /* The pending interrupt is taken right after unmasking interrupts.
   * When the idle thread is scheduled again, execution resumes here,
   * which will result in the loop executing again.
   */
}

This explains why the sceKernelSysroot*AutoClockDown functions only need to atomically increment/decrement a value: if num_active_cores is higher than the amount of CPUs, atomic_sub_32 always returns a non-zero value and the ARM clock is never slowed down.

Version	NID
0.940	0xFA9E2DC5
3.60	sceDsiQueryResolutionSizeForDriver

The typo in the function name was fixed since an unknown FW, and so the NID was updated. See also sceDsiQueryResolutionSizeForDriver.
