* oprofilefs_create_...() do not need superblock argumentAl Viro2013-09-031-6/+6
| | | | | | same story as with oprofilefs_mkdir() Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* oprofilefs_mkdir() doesn't need superblock argumentAl Viro2013-09-031-1/+1
| | | | | | | it's always equal to ->d_sb of the second argument (parent dentry), due to either being literally that, or ->d_sb of parent's parent. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* Disintegrate asm/system.h for AVR32David Howells2012-03-281-1/+0
| | | | | | | Disintegrate asm/system.h for AVR32. This has not been compiled at all. Signed-off-by: David Howells <dhowells@redhat.com> cc: Haavard Skinnemoen <hskinnemoen@gmail.com>
* Add kernel support for oprofile callgraphs on AVR32Nikolaus Voss2008-09-223-1/+86
| | | | | | | | | | This patch adds backtracing capability to oprofile profiling in kernel and user mode on AVR32. This is done by going through the frames on the stack and adding oprofile traces for all return addresses. The code being profiled has to be compiled with frame pointers to make this work.

| | | | | | | Move the only thing that was actually implemented and used in asm/intc.h, intc_get_pending(), into asm/irq.h and delete asm/intc.h Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Oprofile supportHaavard Skinnemoen2008-01-252-0/+243
This adds the necessary architecture code to run oprofile on AVR32 using the performance counters documented by the AVR32 Architecture Manual. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Acked-by: Philippe Elie <phil.el@wanadoo.fr>
