vfs: remove LOOKUP_NO_AUTOMOUNT flag

That flag no longer makes sense, since we don't look up automount points
as eagerly any more.  Additionally, it turns out that the NO_AUTOMOUNT
handling was buggy to begin with: it would avoid automounting even for
cases where we really *needed* to do the automount handling, and could
return ENOENT for autofs entries that hadn't been instantiated yet.

With our new non-eager automount semantics, one discussion has been
about adding a AT_AUTOMOUNT flag to vfs_fstatat (and thus the
newfstatat() and fstatat64() system calls), but it's probably not worth
it: you can always force at least directory automounting by simply
adding the final '/' to the filename, which works for *all* of the stat
family system calls, old and new.

So AT_NO_AUTOMOUNT (and thus LOOKUP_NO_AUTOMOUNT) really were just a
result of our bad default behavior.

vfs pathname lookup: Add LOOKUP_AUTOMOUNT flag

Since we've now turned around and made LOOKUP_FOLLOW *not* force an

lookup even if we don't happen to have one of the other flags that force
it implicitly (LOOKUP_OPEN, LOOKUP_DIRECTORY, LOOKUP_PARENT..)

Most cases will never want to use this, since you'd normally want to
delay automounting as long as possible, which usually implies
LOOKUP_OPEN (when we open a file or directory, we really cannot avoid
the automount any more).

But Trond argued sufficiently forcefully that at a minimum bind mounting
a file and quotactl will want to force the automount lookup.  Some other
cases (like nfs_follow_remote_path()) could use it too, although
LOOKUP_DIRECTORY would work there as well.

This commit just adds the flag and logic, no users yet, though.  It also
doesn't actually touch the LOOKUP_NO_AUTOMOUNT flag that is related, and
was made irrelevant by the same change that made us not follow on
LOOKUP_FOLLOW.

PM / Clocks: Do not acquire a mutex under a spinlock

Commit b7ab83e (PM: Use spinlock instead of mutex in clock
management functions) introduced a regression causing clocks_mutex
to be acquired under a spinlock.  This happens because
pm_clk_suspend() and pm_clk_resume() call pm_clk_acquire() under
pcd->lock, but pm_clk_acquire() executes clk_get() which causes
clocks_mutex to be acquired.  Similarly, __pm_clk_remove(),
executed under pcd->lock, calls clk_put(), which also causes
clocks_mutex to be acquired.

To fix those problems make pm_clk_add() call pm_clk_acquire(), so
that pm_clk_suspend() and pm_clk_resume() don't have to do that.
Change pm_clk_remove() and pm_clk_destroy() to separate
modifications of the pcd->clock_list list from the actual removal of
PM clock entry objects done by __pm_clk_remove().

thus read more than needed and that would cause mismatches and samples
without symbols.

13 years agoperf tool: Fix endianness handling of u32 data in samples
David Ahern [Tue, 6 Sep 2011 15:12:26 +0000 (09:12 -0600)]
perf tool: Fix endianness handling of u32 data in samples

Currently, analyzing PPC data files on x86 the cpu field is always 0 and
the tid and pid are backwards. For example, analyzing a PPC file on PPC
the pid/tid fields show:

        rsyslogd  1210/1212

and analyzing the same PPC file using an x86 perf binary shows:

        rsyslogd  1212/1210

The problem is that the swap_op method for samples is
perf_event__all64_swap which assumes all elements in the sample_data
struct are u64s. cpu, tid and pid are u32s and need to be handled
individually. Given that the swap is done before the sample is parsed,
the simplest solution is to undo the 64-bit swap of those elements when
the sample is parsed and do the proper swap.

The RAW data field is generic and perf cannot have programmatic knowledge
of how to treat that data. Instead a warning is given to the user.

Thanks to Anton Blanchard for providing a data file for a mult-CPU
PPC system so I could verify the fix for the CPU fields.

v3 -> v4:
- fixed use of WARN_ONCE

v2 -> v3:
- used WARN_ONCE for message regarding raw data
- removed struct wrapper around union
- fixed whitespace issues

v1 -> v2:
- added a union for undoing the byte-swap on u64 and redoing swap on
  u32's to address compiler errors (see git commit 65014ab3)

13 years agoperf sort: Fix symbol sort output by separating unresolved samples by type
Anton Blanchard [Wed, 31 Aug 2011 01:51:45 +0000 (11:51 +1000)]
perf sort: Fix symbol sort output by separating unresolved samples by type

I took a profile that suggested 60% of total CPU time was in the
hypervisor:

...
    60.20%  [H] 0x33d43c
     4.43%  [k] ._spin_lock_irqsave
     1.07%  [k] ._spin_lock

Using perf stat to get the user/kernel/hypervisor breakdown contradicted
this.

The problem is we merge all unresolved samples into the one unknown
bucket. If add a comparison by sample type to sort__sym_cmp we get the
real picture:

...
    57.11%  [.] 0x80fbf63c
     4.43%  [k] ._spin_lock_irqsave
     1.07%  [k] ._spin_lock
     0.65%  [H] 0x33d43c

So it was almost all userspace, not hypervisor as the initial profile
suggested.

I found another issue while adding this. Symbol sorting sometimes shows
multiple entries for the unknown bucket:

...
    16.65%  [.] 0x6cd3a8
     7.25%  [.] 0x422460
     5.37%  [.] yylex
     4.79%  [.] malloc
     4.78%  [.] _int_malloc
     4.03%  [.] _int_free
     3.95%  [.] hash_source_code_string
     2.82%  [.] 0x532908
     2.64%  [.] 0x36b538
     0.94%  [H] 0x8000000000e132a4
     0.82%  [H] 0x800000000000e8b0

This happens because we aren't consistent with our sorting. On
one hand we check to see if both symbols match and for two unresolved
samples sym is NULL so we match:

        if (left->ms.sym == right->ms.sym)
                return 0;

On the other hand we use sample IP for unresolved samples when
comparing against a symbol:

       ip_l = left->ms.sym ? left->ms.sym->start : left->ip;
       ip_r = right->ms.sym ? right->ms.sym->start : right->ip;

This means unresolved samples end up spread across the rbtree and we
can't merge them all.

If we use cmp_null all unresolved samples will end up in the one bucket
and the output makes more sense:

...
    39.12%  [.] 0x36b538
     5.37%  [.] yylex
     4.79%  [.] malloc
     4.78%  [.] _int_malloc
     4.03%  [.] _int_free
     3.95%  [.] hash_source_code_string
     2.26%  [H] 0x800000000000e8b0

TPM: TCG_ATMEL should depend on HAS_IOPORT

On m68k, I get:

drivers/char/tpm/tpm_atmel.h: In function ‘atmel_get_base_addr’:
drivers/char/tpm/tpm_atmel.h:129: error: implicit declaration of function ‘ioport_map’
drivers/char/tpm/tpm_atmel.h:129: warning: return makes pointer from integer without a cast

The code in tpm_atmel.h supports PPC64 (using the device tree and ioremap())
and "anything else" (using ioport_map()). However, ioportmap() is only
available on platforms that set HAS_IOPORT.

Although PC64 seems to have HAS_IOPORT, a "depends on HAS_IOPORT" should work,
but I think it's better to expose the special PPC64 handling explicit using
"depends on PPC64 || HAS_IOPORT".

Geert Uytterhoeven [Thu, 22 Sep 2011 19:47:38 +0000 (21:47 +0200)]
zorro: Defer device_register() until all devices have been identified

As the Amiga Zorro II address space is limited to 8.5 MiB and Zorro
devices can contain only one BAR, several Amiga Zorro II expansion
boards (mainly graphics cards) contain multiple Zorro devices: a small
one for the control registers and one (or more) for the graphics memory.

The conversion of cirrusfb to the new driver framework introduced a
regression: the driver contains a zorro_driver for the first Zorro
device, and uses the (old) zorro_find_device() call to find the second
Zorro device.

However, as the Zorro core calls device_register() as soon as a Zorro
device is identified, it may not have identified the second Zorro device
belonging to the same physical Zorro expansion card.  Hence cirrusfb
could no longer find the second part of the Picasso II graphics card,
causing a NULL pointer dereference.

Defer the registration of Zorro devices with the driver framework until
all Zorro devices have been identified to fix this.

Note that the alternative solution (modifying cirrusfb to register a
zorro_driver for all Zorro devices belonging to a graphics card, instead
of only for the first one, and adding a synchronization mechanism to
defer initialization until all have been found), is not an option, as on
some cards one device may be optional (e.g.  the second bank of 2 MiB of
graphics memory on the Picasso IV in Zorro II mode).

hwmon: (coretemp) Don't use threshold registers for tempX_max

With commit c814a4c7c4aad795835583344353963a0a673eb0, the meaning of tempX_max
was changed. It no longer returns the value of bits 8:15 of
MSR_IA32_TEMPERATURE_TARGET, but instead returns the value of CPU threshold
register T1. tempX_max_hyst was added to reflect the value of temperature
threshold register T0.

As it turns out, T0 and T1 are used on some systems, presumably by the BIOS.
Also, T0 and T1 don't have a well defined meaning. The thresholds may be used
as upper or lower limits, and it is not guaranteed that T0 <= T1. Thus, the new
attribute mapping does not reflect the actual usage of the threshold registers.
Also, register contents are changed during runtime by an entity other than the
hwmon driver, meaning the values cached by the driver do not reflect actual
register contents.

Revert most of c814a4c7c4aad795835583344353963a0a673eb0 to address the problem.
Support for T0 and T1 will be added back in with a separate commit, using new
attribute names.
