* [Bug libc/6791] New: Add PROT_SAO define to mman.h to support Strong Access Ordering @ 2008-07-30 22:48 eberlein at us dot ibm dot com 2008-07-30 22:57 ` [Bug libc/6791] " eberlein at us dot ibm dot com ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: eberlein at us dot ibm dot com @ 2008-07-30 22:48 UTC (permalink / raw) To: glibc-bugs This enhancement request is to add the define for PROT_SAO to powerpc/mman.h to match the latest changes in the Linux kernel. This define enables a new hardware feature on Power7 to be used by applications to specify pages in a process's address space that exhibit a stronger memory consistency model, Strong Access Ordering. The justification for the kernel change is in this changeset: http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/ linux-2.6.git;a=commit;h=ef3d3246a0d06be622867d21af25f997aeeb105f The change to powerpc/mman.h is here: http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/ linux-2. 6.git;a=commitdiff;h=aba46c5027cb59d98052231b36efcbbde9c77a1d;hp=b845f313d78e4e259ec449909e3bbadf77b53a6d This patch will create the PROT_SAO define in libc/sysdeps/unix/sysv/linux/powerpc/bits/mman.h to match the linux kernel header in powerpc/mman.h. -- Summary: Add PROT_SAO define to mman.h to support Strong Access Ordering Product: glibc Version: unspecified Status: NEW Severity: enhancement Priority: P2 Component: libc AssignedTo: drepper at redhat dot com ReportedBy: eberlein at us dot ibm dot com CC: glibc-bugs at sources dot redhat dot com,rsa at us dot ibm dot com http://sourceware.org/bugzilla/show_bug.cgi?id=6791 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 5+ messages in thread
