Ben, When you set up your next branch for commits to go in 2.6.36-rc1, please do a pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/paulus/perf.git master to get a series of commits that add support for hw_breakpoint events on 64-bit POWER server processors in the perf_event subsystem. This consists of a commit from me that adds support for most integer instructions to the emulate_step() function, a series from K. Prasad that add the ppc64-specific hw_breakpoint code, and some small commits from me that fix a few bugs that I found in testing. There is one commit in there from K. Prasad that modifies the generic hw_breakpoint code to add the ability to have an arch-specific unregister hook for hw_breakpoints. It has been acked by Frederic Weisbecker. Thanks, Paul. The following changes since commit 7e27d6e778cd87b6f2415515d7127eba53fe5d02: Linux 2.6.35-rc3 (2010-06-11 19:14:04 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/paulus/perf.git master K.Prasad (5): hw_breakpoints: Allow arch-specific cleanup before breakpoint unregistration powerpc, hw_breakpoints: Implement hw_breakpoints for 64-bit server processors powerpc, hw_breakpoint: Handle concurrent alignment interrupts powerpc, hw_breakpoint: Enable hw-breakpoints while handling intervening signals powerpc, hw_breakpoint: Discard extraneous interrupt due to accesses outside symbol length Paul Mackerras (4): powerpc: Emulate most Book I instructions in emulate_step() powerpc, hw_breakpoint: Fix off-by-one in checking access address powerpc, hw_breakpoint: Cooperate better with other single-steppers powerpc, hw_breakpoint: Tell generic code we have no instruction breakpoints arch/powerpc/Kconfig | 1 + arch/powerpc/include/asm/asm-compat.h | 2 + arch/powerpc/include/asm/cputable.h | 4 + arch/powerpc/include/asm/hw_breakpoint.h | 74 ++ arch/powerpc/include/asm/ppc-opcode.h | 7 + arch/powerpc/include/asm/processor.h | 8 + arch/powerpc/kernel/Makefile | 1 + arch/powerpc/kernel/exceptions-64s.S | 1 + arch/powerpc/kernel/hw_breakpoint.c | 364 +++++++ arch/powerpc/kernel/machine_kexec_64.c | 3 + arch/powerpc/kernel/process.c | 14 + arch/powerpc/kernel/ptrace.c | 64 ++ arch/powerpc/kernel/signal.c | 3 + arch/powerpc/kernel/traps.c | 8 +- arch/powerpc/lib/Makefile | 5 +- arch/powerpc/lib/ldstfp.S | 375 ++++++++ arch/powerpc/lib/sstep.c | 1514 +++++++++++++++++++++++++++++- kernel/hw_breakpoint.c | 12 + 18 files changed, 2408 insertions(+), 52 deletions(-) create mode 100644 arch/powerpc/include/asm/hw_breakpoint.h create mode 100644 arch/powerpc/kernel/hw_breakpoint.c create mode 100644 arch/powerpc/lib/ldstfp.S _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
