* arm: kirkwood: topkick: move pinmux configs to the right devicesThomas Petazzoni2013-05-27
| | | | | | | | | | | | | | | | | | | | | | When the pinmux mechanism was added in Kirkwood, the device driver core was not yet providing the possibility of attaching pinmux configurations to all devices, drivers had to do it explicitly, and not all drivers were doing this. Now that the driver core does that in a generic way, it makes sense to attach the pinmux configuration to their corresponding devices. This allows the pinctrl subsystem to show in debugfs to which device is related which pins, for example: pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41 pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42 pin 43 (PIN43): gpio-leds.1 mvebu-gpio:43 function gpio group mpp43 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: Andrew Lunn <andrew@lunn.ch> Tested-By: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

| | | | | | | | | | | | | | | | | | Besides the two "classic" USB interfaces with normal USB ports on the front side, the PlatHome OpenBlocks AX3 uses the third USB interface of the Marvell SoC in the mini-PCIe connector. This allows certain mini-PCIe cards to expose parts of their functionality as a USB peripheral. This commit enables this third USB interface in the OpenBlocks AX3 Device Tree, and also adds comments on top of the two other USB interfaces so that the Device Tree makes it clear which USB interface at the SoC level matches which USB interface visible on the board.

| | | | | | | | | | | | | | | | The Armada XP Development Board (DB-78460-BP) has a NOR flash device connected to the Device Bus. This commit adds the device tree node to support this device. This SoC supports a flexible and dynamic decoding window allocation scheme; but since this feature is still not implemented we need to specify the window base address in the device tree node itself. This base address has been selected in a completely arbitrary fashion.

But when a second function is added, it updates the function records to have the second function also update, but it fails to update the actual function itself. This prevents the second (or third or forth and so on) probes from having their functions called. # echo vfs_symlink:enable_event:sched:sched_switch > set_ftrace_filter # echo vfs_unlink:enable_event:sched:sched_switch > set_ftrace_filter # cat trace # tracer: nop # # entries-in-buffer/entries-written: 0/0 #P:4 # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / delay # TASK-PID CPU# |||| TIMESTAMP FUNCTION # | | | |||| | | # touch /tmp/a # rm /tmp/a # cat trace # tracer: nop # # entries-in-buffer/entries-written: 0/0 #P:4 # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / delay # TASK-PID CPU# |||| TIMESTAMP FUNCTION # | | | |||| | | # ln -s /tmp/a # cat trace # tracer: nop # # entries-in-buffer/entries-written: 414/414 #P:4 # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / delay # TASK-PID CPU# |||| TIMESTAMP FUNCTION # | | | |||| | | <idle>-0 [000] d..3 2847.923031: sched_switch: prev_comm=swapper/0 prev_pid=0 prev_prio=120 prev_state=R ==> next_comm=bash next_pid=2786 next_prio=120 <...>-3114 [001] d..4 2847.923035: sched_switch: prev_comm=ln prev_pid=3114 prev_prio=120 prev_state=x ==> next_comm=swapper/1 next_pid=0 next_prio=120 bash-2786 [000] d..3 2847.923535: sched_switch: prev_comm=bash prev_pid=2786 prev_prio=120 prev_state=S ==> next_comm=kworker/0:1 next_pid=34 next_prio=120 kworker/0:1-34 [000] d..3 2847.923552: sched_switch: prev_comm=kworker/0:1 prev_pid=34 prev_prio=120 prev_state=S ==> next_comm=swapper/0 next_pid=0 next_prio=120 <idle>-0 [002] d..3 2847.923554: sched_switch: prev_comm=swapper/2 prev_pid=0 prev_prio=120 prev_state=R ==> next_comm=sshd next_pid=2783 next_prio=120 sshd-2783 [002] d..3 2847.923660: sched_switch: prev_comm=sshd prev_pid=2783 prev_prio=120 prev_state=S ==> next_comm=swapper/2 next_pid=0 next_prio=120 Still need to update the functions even though the probe itself does not need to be registered again when added a new probe.

| * ftrace: Fix the output of enabled_functions debug fileSteven Rostedt (Red Hat)2013-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The enabled_functions debugfs file was created to be able to see what functions have been modified from nops to calling a tracer. The current method uses the counter in the function record. As when a ftrace_ops is registered to a function, its count increases. But that doesn't mean that the function is actively being traced. /proc/sys/kernel/ftrace_enabled can be set to zero which would disable it, as well as something can go wrong and we can think its enabled when only the counter is set. The record's FTRACE_FL_ENABLED flag is set or cleared when its function is modified. That is a much more accurate way of knowing what function is enabled or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Both __trace_add_new_event() and __trace_early_add_new_event() do basically the same thing, except that __trace_add_new_event() does a little more. Instead of having duplicate code between the two functions, add a helper function trace_create_new_event() that both can use. This will help against having bugs fixed in one function but not the other. Cc: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * tracing: Modify soft-mode only if there's no other referrerMasami Hiramatsu2013-05-09

Without this fix, adding and removing several different enable/disable_event triggers on the same event clear soft-mode bit from the ftrace_event_file. This also happens with a typo of glob on setting triggers. e.g. # echo vfs_symlink:enable_event:net:netif_rx > set_ftrace_filter # cat events/net/netif_rx/enable 0* # echo typo_func:enable_event:net:netif_rx > set_ftrace_filter # cat events/net/netif_rx/enable 0 # cat set_ftrace_filter #### all functions enabled #### vfs_symlink:enable_event:net:netif_rx:unlimited As above, we still have a trigger, but soft-mode is gone.

| * ftrace: Cleanup regex_lock and ftrace_lock around hash updatingMasami Hiramatsu2013-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup regex_lock and ftrace_lock locking points around ftrace_ops hash update code. The new rule is that regex_lock protects ops->*_hash read-update-write code for each ftrace_ops. Usually, hash update is done by following sequence. 1. allocate a new local hash and copy the original hash. 2. update the local hash. 3. move(actually, copy) back the local hash to ftrace_ops. 4. update ftrace entries if needed. 5. release the local hash. This makes regex_lock protect #1-#4, and ftrace_lock to protect #3, #4 and adding and removing ftrace_ops from the ftrace_ops_list. The ftrace_lock protects #3 as well because the move functions update the entries too.

| * ftrace: Have ftrace_regex_write() return either read or errorSteven Rostedt (Red Hat)2013-05-09

Otherwise, it will skip possible other registered probes and by returning a positive number that wasn't read, it will confuse the user processes doing the writing.

But it currently returns the number of registered functions and if it didn't register anything, it returns 0, but that is considered success. This also fixes the return value. As if it succeeds, it returns the number of functions that were enabled, which is returned back to the user in ftrace_regex_write (the write() return code). If only one function is enabled, then the return code of the write is one, and this can confuse the user program in thinking it only wrote 1 byte.
