Following are the new physical and virtual DevHlp routines.

Physical DevHlps

The OS/2 kernel will provide new DevHlps for OS/2 for SMP V2.11 as follows.

DevHlp Functions
Function Name EQU Value Description
DevHlp_CreateSpinLock 111 Create a spinlock - SMP
DevHlp_FreeSpinLock 112 Free a spinlock - SMP
DevHlp_AcquireSpinLock 113 Acquire a spinlock - SMP
DevHlp_ReleaseSpinLock 114 Release a spinlock - SMP
DevHlp_PortIO 118 Port I/O
DevHlp_SetIRQMask 119 Set/Unset an IRQ mask
DevHlp_GetIRQMask 120 Get an IRQ mask

Virtual Device Driver Helps

The OS/2 kernel will provide new VDH services for VDDs to communicate with PSDs.
