The entire file of ftrace.c in the arch code needs to be marked as notrace. It is much cleaner to do this from the Makefile with CFLAGS_REMOVE_ftrace.o. [ powerpc already had this in its Makefile. ] Signed-off-by: NSteven Rostedt <srostedt@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

Due to confusion between the ftrace infrastructure and the gcc profiling tracer "ftrace", this patch renames the config options from FTRACE to FUNCTION_TRACER. The other two names that are offspring from FTRACE DYNAMIC_FTRACE and FTRACE_MCOUNT_RECORD will stay the same. This patch was generated mostly by script, and partially by hand.

This patch introduces microcode patch loading for AMD processors. It is based on previous corresponding work for Intel processors. It hooks into the general patch loading module. Main difference is that a container file format is used to hold all patch data for multiple processors as well as an equivalent CPU table, which comes seperately, as opposed to Intel's microcode patching solution. Kconfig and Makefile have been changed provice config and build option for new source file.

Refactored code by introducing a two-module solution. There is one general module in which vendor specific modules can hook into. However, that is exclusive, there is only one vendor specific module allowed at a time. A CPU vendor check makes sure only the correct module for the underlying system gets called. Functinally in terms of patch loading itself there are no changes. This refactoring provides a basis for future implementations of other vendors' patch loaders.

ftrace requires certain low-level code, like spinlocks and timestamps, to be compiled without -pg in order to avoid infinite recursion. This patch splits out the core paravirt spinlocks and the Xen spinlocks into separate files which can be compiled without -pg. Also do xen/time.c while we're about it. As a result, we can now use ftrace within a Xen domain. Signed-off-by: NJeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

-tip testing found a bootup hang here: initcall anon_inode_init+0x0/0x130 returned 0 after 0 msecs calling acpi_event_init+0x0/0x57 the bootup should have continued with: initcall acpi_event_init+0x0/0x57 returned 0 after 45 msecs but it hung hard there instead. bisection led to this commit: | commit 5806b81a | Merge: d14c8a68... 6712e299... | Author: Ingo Molnar <mingo@elte.hu> | Date: Mon Jul 14 16:11:52 2008 +0200 | Merge branch 'auto-ftrace-next' into tracing/for-linus turns out that i made this mistake in the merge: ifdef CONFIG_FTRACE # Do not profile debug utilities CFLAGS_REMOVE_tsc_64.o = -pg CFLAGS_REMOVE_tsc_32.o = -pg those two files got unified meanwhile - so the dont-profile annotation got lost.

the paravirt-spinlock patches caused a boot hang with this config: http://redhat.com/~mingo/misc/config-Wed_Jul__9_14_47_04_CEST_2008.bad i have bisected it down to: | commit e17b58c2e85bc2ad2afc07fb8d898017c2b75ed1 | Author: Jeremy Fitzhardinge <jeremy@goop.org> | Date: Mon Jul 7 12:07:53 2008 -0700 | | xen: implement Xen-specific spinlocks i.e. applying that patch alone causes the hang. The hang happens in the ftrace self-test: initcall utsname_sysctl_init+0x0/0x19 returned 0 after 0 msecs calling init_sched_switch_trace+0x0/0x4c Testing tracer sched_switch: PASSED initcall init_sched_switch_trace+0x0/0x4c returned 0 after 167 msecs calling init_function_trace+0x0/0x12 Testing tracer ftrace: [hard hang] it should have continued like this: Testing tracer ftrace: PASSED initcall init_function_trace+0x0/0x12 returned 0 after 198 msecs calling init_irqsoff_tracer+0x0/0x14 Testing tracer irqsoff: PASSED initcall init_irqsoff_tracer+0x0/0x14 returned 0 after 3 msecs calling init_mmio_trace+0x0/0x12 initcall init_mmio_trace+0x0/0x12 returned 0 after 0 msecs the problem is that such lowlevel primitives as spinlocks should never be built with -pg (which ftrace does). Marking paravirt.o as non-pg and marking all spinlock ops as always-inline solve the hang. Signed-off-by: NIngo Molnar <mingo@elte.hu>

TLB shootdown for SGI UV. Depends on patch (in tip/x86/irq): x86-update-macros-used-by-uv-platform.patch Jack Steiner May 29 This patch provides the ability to flush TLB's in cpu's that are not on the local node. The hardware mechanism for distributing the flush messages is the UV's "broadcast assist unit". The hook to intercept TLB shootdown requests is a 2-line change to native_flush_tlb_others() (arch/x86/kernel/tlb_64.c). This code has been tested on a hardware simulator. The real hardware is not yet available. The shootdown statistics are provided through /proc/sgi_uv/ptc_statistics. The use of /sys was considered, but would have required the use of many /sys files. The debugfs was also considered, but these statistics should be available on an ongoing basis, not just for debugging. Issues to be fixed later: - The IRQ for the messaging interrupt is currently hardcoded as 200 (see UV_BAU_MESSAGE). It should be dynamically assigned in the future. - The use of appropriate udelay()'s is untested, as they are a problem in the simulator.
