RE: interesting option of stap


Right, my bad. I think I read your previous mail too fast like "In recent upstream kernel sources, arch/arm/kernel/vmlinux.lds.S should use the NOTES macro..." whereas you stated "uses". Well, it was past midnight for me :-(

I'll try to follow-up in Linaro if I get reasons why it is placed there. I guess that closes the topic ;-)

> Someone from Linaro pointed me to a very recent commit on ARM kernel http://ftp.arm.linux.org.uk/git/gitweb.cgi?p=linux-2.6-arm.git;a=commitdiff;h=dc810efb0ca5702c9d with good comments.

I mentioned before that the mainline arm code has this.  Note that, as I mentioned before, it is not really placed where it should be--it will be writable when it should be rodata.  (The sample comment in vmlinux.lds.h puts RO_DATA, EXCEPTION_TABLE, and NOTES all in stupid places not matching where canonical cases like x86 actually put them.)  Though it's not a wise placement and IMHO ought it to be fixed, it should work fine as it is.


Thanks,
Roland
