New options in Kconfig allow the platform binding code and/or the of_platform code to be turned on. The of_platform code is of course only available on archs that have OF support. The existing probe and remove methods are refactored to use new functions create_gpio_led(), to create and register one led, and delete_gpio_led(), to unregister and free one led. The new probe and remove methods for the of_platform driver can then share most of the common probe and remove code with the platform driver. The suspend and resume methods aren't shared, but they are very short. The actual led driving code is the same for LEDs created by either binding. The OF bindings are based on patch by Anton Vorontsov <avorontsov@ru.mvista.com>. They have been extended to allow multiple LEDs per device.

* | | | perf_counter tools: optionally scale counter values in perfstat modePaul Mackerras2009-04-061-11/+45

This is invoked with the -l option (I used 'l' because s, c, a and e were all taken already.) This uses the new PERF_RECORD_TOTAL_TIME_{ENABLED,RUNNING} read format options. With this, we get output like this: $ ./perfstat -l -e 0:0,0:1,0:2,0:3,0:4,0:5 ./spin Performance counter stats for './spin': 4016072055 CPU cycles (events) (scaled from 66.53%) 2005887318 instructions (events) (scaled from 66.53%) 1762849 cache references (events) (scaled from 66.69%) 165229 cache misses (events) (scaled from 66.85%) 1001298009 branches (events) (scaled from 66.78%) 41566 branch misses (events) (scaled from 66.61%) Wall-clock time elapsed: 2438.227446 msecs This also lets us detect when a counter is zero because the counter never got to go on the CPU at all. In that case we print <not counted> rather than 0.

This adds a 'next' field to struct source_line, which lets us link them together into a list. The code to do the linking ourselves turns out to be no longer or more difficult than using glib. This also fixes a few other problems: - We need to #include <limits.h> to get PATH_MAX on powerpc. - We need to #include <linux/types.h> rather than have our own definitions of __u64 and __s64; on powerpc the installed headers define them to be unsigned long and long respectively, and if we have our own, different definition here that causes a compile error. - This takes out the x86 setting of errno from -ret in sys_perf_counter_open. My experiments on x86 indicate that the glibc syscall() does this for us already. - We had two CPU migration counters in the default set, which seems unnecessary; I changed one of them to a context switch counter. - In perfstat mode we were printing CPU cycles and instructions as milliseconds, and the cpu clock and task clock counters as events. This fixes that. - In perfstat mode we were still printing a blank line after the first counter, which was a holdover from when a task clock counter was automatically included as the first counter. This removes the blank line. - On a test machine here, parse_symbols() and parse_vmlinux() were taking long enough (almost 0.5 seconds) for the mmap buffer to overflow before we got to the first mmap_read() call, so this moves them before we open all the counters. - The error message if sys_perf_counter_open fails needs to use errno, not -fd[i][counter].

The patch is mainly aimed to block native hwmon drivers from touching monitoring chips that ACPI thinks it own. If this causes a regression, boot with "acpi_enforce_resources=lax" which was the previous default. http://bugzilla.kernel.org/show_bug.cgi?id=12376 http://bugzilla.kernel.org/show_bug.cgi?id=12541 Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Acked-by: Pavel Machek <pavel@suse.cz> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Len Brown <len.brown@intel.com>

In order to fix bugzilla #11750... Add a new brightness control mode: support direct NVRAM checkpointing of the backlight level (i.e. store directly to NVRAM without the need for UCMS calls), and use that together with the EC-based control. Disallow UCMS+EC, thus avoiding races with the SMM firmware. Switch the models that define HBRV (EC Brightness Value) in the DSDT to the new mode. These are: T40-T43, R50-R52, R50e, R51e, X31-X41. Change the default for all other IBM ThinkPads to UCMS-only. The Lenovo models already default to UCMS-only.
