we start a infinite loop when user gives ./watchdog-test, and when user
ctrl + c's the program, we just exit immeadiately with out closing the
filedescriptor of the watchdog device. a signal handler is used to
do the job of closing the filedescriptor and exiting the program.

While rebasing my "watchdog_dev: Let the driver update the timeout field on
set_timeout success" patch (before I noticed it was already picked up by Wim),
I noticed that the s3c2410_wdt driver may not always have a 1 second
resolution, this patch changes s3c2410wdt_set_heartbeat to update the
timeout to the actually achieved timeout.

The SCH311x chip contains 2 watchdogs. One is the watchdog programmable
by the runtime register at address 0x65-0x68, the other is the watchdog
inside the power on reset generator. This second watchdog has a fixed
timeout value of ~1.6 seconds and is configurable only by the RESGEN
register.
The BIOS normally takes care of the RESGEN watchdog and disables it (at
least) before the OS is booted.
Unfortunately the sch311x_wdt driver clears bit 0 of the RESGEN register
which has the effect that at the latest 1.6 seconds later, a POR is
triggered.
The attached patch fixes this problem by completely removing any
reference to the RESGEN watchdog from the sch311x_wdt driver.

A user has several systems with a couple of models of flash disks with IDE
connectors. These disks work fine in 2.6.18-ish kernels but corrupt data on
new kernels.
The difference appears to be with the default I/O method used by the IDE
controller driver between the kernels. In the older kernels, the
configuration is very conservative and the driver stays in PIO mode. With
new kernels, the ata driver (pata_serverworks) attempts to use UDMA/66
which the drive claims to support. This mode, however, does not appear to
work in DMA mode. The drive does work correctly and no corruption is
seen if the kernel parameter "libata.force=5:pio0,6:pio0" is used to force
the driver to use PIO instead of DMA mode.
Blacklist these drives. Unfortunately the model name of the drive is very
generic, " 2GB ATA Flash Disk", but the revision is specific, "ADMA428M".

Commit 4d7e30d (epoll: Add a flag, EPOLLWAKEUP, to prevent
suspend while epoll events are ready) caused some applications to
malfunction, because they set the bit corresponding to the new
EPOLLWAKEUP flag in their eventpoll flags and they don't have the
new CAP_EPOLLWAKEUP capability.
To prevent that from happening, change epoll_ctl() to clear
EPOLLWAKEUP in epds.events if the caller doesn't have the
CAP_EPOLLWAKEUP capability instead of failing and returning an
error code, which allows the affected applications to function
normally.

Quoting Ingo:
"While at it I'd also suggest increasing the default sampling frequency,
from 1000 Hz per CPU to at least 4Khz auto-freq or so - this should work
well all across the board I think. CPUs are getting faster and command/app
run times are getting shorter, 1Khz is a bit low IMO."

In order for perf buildid-list to work with pipe-mode files, it needs to
process buildids and event attr structs.
$ perf record -o - noploop 2 | ./perf inject -b | perf buildid-list -i - -H
noploop for 2 seconds
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.084 MB - (~3678 samples) ]
0000000000000000000000000000000000000000 [kernel.kallsyms]
3a0d0629efe74a8da3eeba372cdbd74ad9b8f5d5 /usr/local/bin/noploop
The reason [kernel.kallsyms] shows a 0 build-id comes from the
way buildids are injected in the stream.
The buildid for the kernel is provided by a BUILD_ID record. The
[kernel.kallsyms] is provided by a MMAP record. There is no clean and
obvious way to link the two, unfortunately.
In regular mode, the kernel buildid is generated from reading the ELF
image or kallsyms and perf knows to associate [kernel.kallsyms] to it.
Later on, when perf processes the [kernel.kallsyms] MMAP record, it will
already have a dso for it.
So for now, make sure perf buildid-list shows the buildids for
everything but the kernel image.

In __perf_session__process_pipe_events(), there was a risk we would read
more than what a union perf_event struct can hold. this could happen in
case, perf is reading a file which contains new record types it does not
know about and which are larger than anything it knows about.
In general, perf is supposed to skip records it does not understand, but
in pipe mode, those have to be read and ignored. The fixed size header
contains the size of the record, but that size may be larger than union
perf_event, yet it was used as the backing to the read in:
union perf_event event;
void *p;
size = event->header.size;
p = &event;
p += sizeof(struct perf_event_header);
if (size - sizeof(struct perf_event_header)) {
err = readn(self->fd, p, size - sizeof(struct perf_event_header));
We fix this by allocating a buffer based on the size reported in the
header. We reuse the buffer as much as we can. We realloc in case it
becomes too small. In the common case, the performance impact is
negligible.

perf inject -b was broken. It would not inject any build_id into the
stream. Furthermore, it would strip samples from the stream.
The reason was a missing initialization of the event attribute
structure. The perf_tool.tool.attr() callback was pointing to a simple
repipe. But there was no initialization of the internal data structures
to keep track of events and event ids. That later caused event id
lookups to fail, and sample would get removed.
The patch simply adds back the call to perf_event__process_attr() to
initialize the evlist structure and now build_ids are again injected.

When the perf data file is read cross architectures, the
perf_event__attr_swap function takes care about endianness of all the
struct fields except the bitfield flags.
The bitfield flags need to be transformed as well, since the bitfield
binary storage differs for both endians.
ABI says:
Bit-fields are allocated from right to left (least to most significant)
on little-endian implementations and from left to right (most to least
significant) on big-endian implementations.
The above seems to be byte specific, so we need to reverse each byte of
the bitfield. 'Internet' also says this might be implementation specific
and we probably need proper fix and carry perf_event_attr bitfield flags
in separate data file FEAT_ section. Thought this seems to work for now.
Note, running following to test perf endianity handling:
test 1)
- origin system:
# perf record -a -- sleep 10 (any perf record will do)
# perf report > report.origin
# perf archive perf.data
- copy the perf.data, report.origin and perf.data.tar.bz2
to a target system and run:
# tar xjvf perf.data.tar.bz2 -C ~/.debug
# perf report > report.target
# diff -u report.origin report.target
- the diff should produce no output
(besides some white space stuff and possibly different
date/TZ output)
test 2)
- origin system:
# perf record -ag -fo /tmp/perf.data -- sleep 1
- mount origin system root to the target system on /mnt/origin
- target system:
# perf script --symfs /mnt/origin -I -i /mnt/origin/tmp/perf.data \
--kallsyms /mnt/origin/proc/kallsyms
- complete perf.data header is displayed

Handle the print argument types brought by the new libparsevent in perl
scripting engine.
PRINT_BSTRING and PRINT_DYNAMIC_ARRAY are treated just like strings
and thus don't require specific processing.
But PRINT_FUNC need specific plugins which are not yet handled, lets
warn if we meet this case.
This fixes:
util/scripting-engines/trace-event-perl.c: In function define_event_symbol:
util/scripting-engines/trace-event-perl.c:188: error: enumeration value PRINT_BSTRING not handled in switch
util/scripting-engines/trace-event-perl.c:188: error: enumeration value PRINT_DYNAMIC_ARRAY not handled in switch
util/scripting-engines/trace-event-perl.c:188: error: enumeration value PRINT_FUNC not handled in switch

Adding a new hardcoded term 'name' allowing to specify a name for the
pmu event. The term is defined along with standard pmu terms. If no
'name' term is given, the event name follows following template:
"raw 0x<perf_event_attr::config>"
running:
perf stat -e cpu/config=1,name=krava1/u ls
will produce following output:
...
Performance counter stats for 'ls':
0 krava1
...
running:
perf stat -e cpu/config=1/u ls
will produce following output:
...
Performance counter stats for 'ls':
0 raw 0x1
...

Separating 'mem:' scanner processing, so we can parse out modifier
specifically and dont clash with other rules.
This is just precaution for the future, so we dont need to worry about
the rules clashing where we need to parse out any sub-rule of global
rules.

Switch from using static temporary event list into dynamically allocated
one. This way we dont need to pass temp list to the parse_events_parse
which makes the interface more clear.

Adding PARSER_DEBUG Makefile variable to enable building event scanner/
parser with debug enabled. This results in verbose output right out of
the scanner/parser.
It's useful for debuging the event parser. Keeping this only for event
parser so far.
