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.
