modification history
|
||||
--------------------
|
||||
01p,08sep10,pcs Add an entry to represent the global virtual memory region
|
||||
size to struct adrSpaceInitParams.
|
||||
01o,02jun10,elp added SIMNT/SIMLINUX 64 bits support.
|
||||
01n,29apr10,pad Moved extern C statement after include statements.
|
||||
01m,14apr10,jpb Added function pointer declarations.
|
||||
01l,09mar10,pad Reorganized ADR_SPACE_INIT_PARAMS structure so that only the
|
||||
localMemLocalAdrs field is defined for VxWorks 64-bit.
|
||||
01k,27oct09,pcs Rearranged struct adrSpaceInitParams entries while adding
|
||||
support for RTP's in LP64.
|
||||
01j,12oct09,zl added adrSpaceOptimizedSizeGet()and RAM pool allocation option
|
||||
01i,17sep09,zl added directMapRAMSize.
|
||||
01h,24aug09,zl updated map and alloc options; added 64-bit arch header
|
||||
01g,22jun09,zl updated for LP64 build
|
||||
01f,18apr08,pcs Add prototypes for adrSpaceOverlapPageAlloc and
|
||||
adrSpaceOverlapNodesRemove.
|
||||
01e,24apr07,pcs Add prototype for adrSpacePageVirtPhysFree.
|
||||
01d,09sep05,zl removed ADR_SPACE_RGN_CTL structure.
|
||||
01c,27jun05,zl added new alloc, free, map, unmap APIs and options.
|
||||
01b,22sep04,zl post-inspection fixes.
|
||||
01a,31aug04,zl created.
