ld.hugetlbfs
LD.HUGETLBFS(1) General Commands Manual LD.HUGETLBFS(1)
NAME
ld.hugetlbfs - link a program for huge pages
SYNOPSIS
ld.hugetlbfs [options]
DESCRIPTION
ld.hugetlbfs replaces the normal ld command for linking programs to use hugepages. Under gcc, you should use the option -B /usr/share/lib-
hugetlbfs which tells gcc to look in a non-standard location for the linker. This could be set in the CFLAGS environment variable.
-Wl,--hugetlbfs-align
This method of linking an application permits greater flexibility at runtime. Using HUGETLB_ELFMAP, it is possible to control which
program segments are placed in hugepages. The following four settings will cause the indicated segments to be placed in hugepages:
HUGETLB_ELFMAP=R Read-only segments (text)
HUGETLB_ELFMAP=W Writable segments (data/BSS)
HUGETLB_ELFMAP=RW All segments (text/data/BSS)
HUGETLB_ELFMAP=no No segments
It is possible to select specific huge page sizes for read-only and writable segments by using the following advanced syntax:
HUGETLB_ELFMAP=[R[=<pagesize>]:[W[=<pagesize>]]
-Wl,--hugetlbfs-link=B
Under binutils 2.16 or older, this option will link the application to store BSS data (only) into hugepages.
-Wl,--hugetlbfs-link=BDT
Under binutils 2.16 or older, this option will link the application to store text, initialized data and BSS data into hugepages.
