Optional OAL Variables (Compact 2013)

10/16/2014

The following table shows the optional OAL variables.

Variables	Description
cbCoProcRegSize	Describes the size of the memory allocation, in bytes, that is needed for the OEM to save or restore coprocessor registers.
cbErrReportSize	Specifies the amount of memory for the Windows Embedded Compact Error Reporting dump area.
DefaultThreadQuantum	Sets the default thread quantum of all threads.
dwAlarmResolution	Specifies the resolution of the kernel alarm timer to 1 second.
dwARM1stLvlBits	Specifies the extra bits to be set in the first-level page table.
dwARMCacheMode	Specifies the C and B bits that the kernel uses to build the page tables on an ARM platform.
dwCeLogLargeBuf	Adjusts the size of the main logging buffer.
dwCeLogSmallBuf	Adjusts the size of the secondary logging buffer. It is used by the OEM.
dwCeLogTLBMiss	Specifies how many translation look-aside buffer (TLB) misses have occurred for the last thread that was running.
dwMainMemoryEndAddress	Specifies the next available address following the first available contiguous block of memory.
dwPageTableCacheBits	Specifies cache bits for the OS uses to access the inner and outer page tables.
dwPlatformFlags	Specifies platform capabilities such as vector floating-point (VFP) support.
dwTTBRCacheBits	Specifies cache bits for page tables in the Translation Table Base Register (TTBR) if the page tables can be cached.
dwWatchDogThreadPriority	Specifies a kernel watchdog thread.
dwWatchDogPeriod	Specifies the watchdog period, in milliseconds, where the hardware watchdog must be refreshed before system resets.
dwYearsRTCRollover	Specifies the number of years for the real-time clock (RTC) to roll over.
fMpEnable	Specifies whether multiprocessor support is enabled.
fSaveCoProcReg	Tells the kernel when the save or restore of coprocessors registers is performed.
PageOutHigh	Sets the amount of memory above which pages are not freed by the trimmer thread.
PageOutLow	Sets the threshold below which pages are freed by the trimmer thread.
