What: /sys/class/backlight/<backlight>/ambient_light_zone
Date: Mai 2011
KernelVersion: 2.6.40
Contact: device-drivers-devel@blackfin.uclinux.org
Description:
Get/Set current ambient light zone. Reading returns
integer between 1..5 (1 = daylight, 2 = bright, ..., 5 = dark).
Writing a value between 1..5 forces the backlight controller
to enter the corresponding ambient light zone.
Writing 0 returns to normal/automatic ambient light level
operation. The ambient light sensing feature on these devices
is an extension to the API documented in
Documentation/ABI/stable/sysfs-class-backlight.
It can be enabled by writing the value stored in
/sys/class/backlight/<backlight>/max_brightness to
/sys/class/backlight/<backlight>/brightness.

useful for providing visibility into the numa locality information within

combining this information with the application's cpu allocation.

Kmemleak is supported on x86, arm, powerpc, sparc, sh, microblaze and tile.
Please check DEBUG_KMEMLEAK dependencies in lib/Kconfig.debug for supported
architectures.

@ -9,7 +9,121 @@ If variable is of Type, use printk format specifier:
size_t %zu or %zx
ssize_t %zd or %zx
Raw pointer value SHOULD be printed with %p.
Raw pointer value SHOULD be printed with %p. The kernel supports
the following extended format specifiers for pointer types:
Symbols/Function Pointers:
%pF versatile_init+0x0/0x110
%pf versatile_init
%pS versatile_init+0x0/0x110
%ps versatile_init
%pB prev_fn_of_versatile_init+0x88/0x88
For printing symbols and function pointers. The 'S' and 's' specifiers
result in the symbol name with ('S') or without ('s') offsets. Where
this is used on a kernel without KALLSYMS - the symbol address is
printed instead.
The 'B' specifier results in the symbol name with offsets and should be
used when printing stack backtraces. The specifier takes into
consideration the effect of compiler optimisations which may occur
when tail-call's are used and marked with the noreturn GCC attribute.
On ia64, ppc64 and parisc64 architectures function pointers are
actually function descriptors which must first be resolved. The 'F' and
'f' specifiers perform this resolution and then provide the same
functionality as the 'S' and 's' specifiers.
Kernel Pointers:
%pK 0x01234567 or 0x0123456789abcdef
For printing kernel pointers which should be hidden from unprivileged
users. The behaviour of %pK depends on the kptr_restrict sysctl - see
Documentation/sysctl/kernel.txt for more details.
Struct Resources:
%pr [mem 0x60000000-0x6fffffff flags 0x2200] or
[mem 0x0000000060000000-0x000000006fffffff flags 0x2200]
%pR [mem 0x60000000-0x6fffffff pref] or
[mem 0x0000000060000000-0x000000006fffffff pref]
For printing struct resources. The 'R' and 'r' specifiers result in a
printed resource with ('R') or without ('r') a decoded flags member.
MAC/FDDI addresses:
%pM 00:01:02:03:04:05
%pMF 00-01-02-03-04-05
%pm 000102030405
For printing 6-byte MAC/FDDI addresses in hex notation. The 'M' and 'm'
specifiers result in a printed address with ('M') or without ('m') byte
separators. The default byte separator is the colon (':').
Where FDDI addresses are concerned the 'F' specifier can be used after
the 'M' specifier to use dash ('-') separators instead of the default
separator.
IPv4 addresses:
%pI4 1.2.3.4
%pi4 001.002.003.004
%p[Ii][hnbl]
For printing IPv4 dot-separated decimal addresses. The 'I4' and 'i4'
specifiers result in a printed address with ('i4') or without ('I4')
leading zeros.
The additional 'h', 'n', 'b', and 'l' specifiers are used to specify
host, network, big or little endian order addresses respectively. Where
no specifier is provided the default network/big endian order is used.
IPv6 addresses:
%pI6 0001:0002:0003:0004:0005:0006:0007:0008
%pi6 00010002000300040005000600070008
%pI6c 1:2:3:4:5:6:7:8
For printing IPv6 network-order 16-bit hex addresses. The 'I6' and 'i6'
specifiers result in a printed address with ('I6') or without ('i6')
colon-separators. Leading zeros are always used.
The additional 'c' specifier can be used with the 'I' specifier to
print a compressed IPv6 address as described by
http://tools.ietf.org/html/rfc5952
UUID/GUID addresses:
%pUb 00010203-0405-0607-0809-0a0b0c0d0e0f
%pUB 00010203-0405-0607-0809-0A0B0C0D0E0F
%pUl 03020100-0504-0706-0809-0a0b0c0e0e0f
%pUL 03020100-0504-0706-0809-0A0B0C0E0E0F
For printing 16-byte UUID/GUIDs addresses. The additional 'l', 'L',
'b' and 'B' specifiers are used to specify a little endian order in
lower ('l') or upper case ('L') hex characters - and big endian order
in lower ('b') or upper case ('B') hex characters.
Where no additional specifiers are used the default little endian
order with lower case hex characters will be printed.
struct va_format:
%pV
For printing struct va_format structures. These contain a format string
and va_list as follows:
struct va_format {
const char *fmt;
va_list *va;
};
Do not use this feature without some mechanism to verify the
correctness of the format string and va_list arguments.
