Dear, all
I want to allocate a page at 0x38000 - 0x38FFF but failed.
The error log is “ConvertPages: failed to find range 38000 - 38FFF” in
function CoreConvertPages (in MdeModulePkg/Core/Dxe/Mem/Page.c)
I add debug message in CoreConvertPages
for (Link = gMemoryMap.ForwardLink; Link != &gMemoryMap; Link =
Link->ForwardLink) {
Entry = CR (Link, MEMORY_MAP, Link, MEMORY_MAP_SIGNATURE);
DEBUG ((DEBUG_INFO, "ConvertRange: Entry->Start==0x%lx,
Entry->End==0x%lx\n", Entry->Start, Entry->End));
if (Entry->Start <= Start && Entry->End > Start) {
break;
}
}
The debug message is:
ConvertRange: Entry->Start==0x86000, Entry->End==0x9FFFF
ConvertRange: Entry->Start==0x105000, Entry->End==0x9FC02FFF
ConvertRange: Entry->Start==0x9FC03000, Entry->End==0x9FC04FFF
ConvertRange: Entry->Start==0x9FC05000, Entry->End==0x9FC09FFF
ConvertRange: Entry->Start==0x9FC0A000, Entry->End==0x9FC0AFFF
ConvertRange: Entry->Start==0x9FC0B000, Entry->End==0x9FC0BFFF
ConvertRange: Entry->Start==0x100000000, Entry->End==0x11ED8FFFF
ConvertRange: Entry->Start==0x11ED90000, Entry->End==0x11F400FFF
ConvertRange: Entry->Start==0x11F401000, Entry->End==0x11F4D0FFF
ConvertRange: Entry->Start==0x11F4D1000, Entry->End==0x11F67BFFF
ConvertRange: Entry->Start==0x11F67C000, Entry->End==0x11F87BFFF
ConvertRange: Entry->Start==0x11F87C000, Entry->End==0x11FA7BFFF
ConvertRange: Entry->Start==0x11FA7C000, Entry->End==0x11FC2DFFF
ConvertRange: Entry->Start==0x11FC2E000, Entry->End==0x11FC7BFFF
ConvertRange: Entry->Start==0x11FC7C000, Entry->End==0x11FD68FFF
ConvertRange: Entry->Start==0x11FD69000, Entry->End==0x11FD7BFFF
ConvertRange: Entry->Start==0x11FD7C000, Entry->End==0x11FE5FFFF
ConvertRange: Entry->Start==0x11FE60000, Entry->End==0x11FE7BFFF
ConvertRange: Entry->Start==0x11FE7C000, Entry->End==0x11FFFFFFF
ConvertPages: failed to find range 38000 - 38FFF
My question is how to add a memory range to gMemoryMap?
Any help with this would be greatly appreciated.
Yours sincerely,
WANG Siyuan
