2008-07-26Oprofile Multiplexing PatchJason Yeh
This patch introduces multiplexing support for the Oprofile kernel module. It basically adds a new function pointer in oprofile_operator allowing each architecture to supply its callback to switch between different sets of event when the timer expires. Userspace tools can modify the time slice through /dev/oprofile/time_slice. It also modifies the number of counters exposed to the userspace through /dev/oprofile. For example, the number of counters for AMD CPUs are changed to 32 and multiplexed in the sets of 4.

Change the following arrays sized by NR_CPUS to be PERCPU variables: static struct op_msrs cpu_msrs[NR_CPUS]; static unsigned long saved_lvtpc[NR_CPUS]; Also some minor complaints from checkpatch.pl fixed. Based on: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git All changes were transparent except for: static void nmi_shutdown(void) { + struct op_msrs *msrs = &__get_cpu_var(cpu_msrs); nmi_enabled = 0; on_each_cpu(nmi_cpu_shutdown, NULL, 0, 1); unregister_die_notifier(&profile_exceptions_nb); - model->shutdown(cpu_msrs); + model->shutdown(msrs); free_msrs(); } The existing code passed a reference to cpu 0's instance of struct op_msrs to model->shutdown, whilst the other functions are passed a reference to <this cpu's> instance of a struct op_msrs. This seemed to be a bug to me even though as long as cpu 0 and <this cpu> are of the same type it would have the same effect...?

2008-01-30x86: pull bp calculation earlier into the backtrace pathArjan van de Ven
Right now, we take the stack pointer early during the backtrace path, but only calculate bp several functions deep later, making it hard to reconcile the stack and bp backtraces (as well as showing several internal backtrace functions on the stack with bp based backtracing). This patch moves the bp taking to the same place we take the stack pointer; sadly this ripples through several layers of the back tracing stack, but it's not all that bad in the end I hope.

For enhancing the 32 bit EBP based backtracer, I need the capability for the backtracer to tell it's customer that an entry is either reliable or unreliable, and the backtrace printing code then needs to print the unreliable ones slightly different. This patch adds the basic capability, the next patch will add a user of this capability.

2008-01-30x86: rename the struct pt_regs members for 32/64-bit consistencyH. Peter Anvin
We have a lot of code which differs only by the naming of specific members of structures that contain registers. In order to enable additional unifications, this patch drops the e- or r- size prefix from the register names in struct pt_regs, and drops the x- prefixes for segment registers on the 32-bit side. This patch also performs the equivalent renames in some additional places that might be candidates for unification in the future. Signed-off-by: H.

2008-01-24Driver core: change sysdev classes to use dynamic kobject namesKay Sievers
All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-01-18x86: add support for the latest Intel processors to OprofileArjan van de Ven
The latest Intel processors (the 45nm ones) have a model number of 23 (old ones had 15); they're otherwise compatible on the oprofile side. This patch adds the new model number to the oprofile code.
