* ad525x_dpot: add support for SPI partsMichael Hennerich2010-05-25
| | | | | | | | | | | | | | | | | | Split the bus logic out into separate files so that we can handle I2C and SPI busses independently. The new SPI bus logic brings in support for a lot more parts: AD5160, AD5161, AD5162, AD5165, AD5200, AD5201, AD5203, AD5204, AD5206, AD5207, AD5231, AD5232, AD5233, AD5235, AD5260, AD5262, AD5263, AD5290, AD5291, AD5292, AD5293, AD7376, AD8400, AD8402, AD8403, ADN2850 [randy.dunlap@oracle.com: fix ad525X_dpot build] Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * VMware Balloon driverDmitry Torokhov2010-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a standalone version of VMware Balloon driver. Ballooning is a technique that allows hypervisor dynamically limit the amount of memory available to the guest (with guest cooperation). In the overcommit scenario, when hypervisor set detects that it needs to shuffle some memory, it instructs the driver to allocate certain number of pages, and the underlying memory gets returned to the hypervisor. Later hypervisor may return memory to the guest by reattaching memory to the pageframes and instructing the driver to "deflate" balloon. We are submitting a standalone driver because KVM maintainer (Avi Kivity) expressed opinion (rightly) that our transport does not fit well into virtqueue paradigm and thus it does not make much sense to integrate with virtio. There were also some concerns whether current ballooning technique is the right thing. If there appears a better framework to achieve this we are prepared to evaluate and switch to using it, but in the meantime we'd like to get this driver upstream. We want to get the driver accepted in distributions so that users do not have to deal with an out-of-tree module and many distributions have "upstream first" requirement. The driver has been shipping for a number of years and users running on VMware platform will have it installed as part of VMware Tools even if it will not come from a distribution, thus there should not be additional risk in pulling the driver into mainline. The driver will only activate if host is VMware so everyone else should not be affected at all.

* | kgdb: add kgdb internal test suiteJason Wessel2008-04-17
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds regression tests for testing the kgdb core and arch specific implementation. The kgdb test suite is designed to be built into the kernel and not as a module because it uses a number of low level kernel and kgdb primitives which should not be exported externally. The kgdb test suite is designed as a KGDB I/O module which simulates the communications that a debugger would have with kgdb. The tests are broken up in to a line by line and referenced here as a "get" which is kgdb requesting input and "put" which is kgdb sending a response. The kgdb suite can be invoked from the kernel command line arguments system or executed dynamically at run time. The test suite uses the variable "kgdbts" to obtain the information about which tests to run and to configure the verbosity level. The following are the various characters you can use with the kgdbts= line: When using the "kgdbts=" you only choose one of the following core test types: A = Run all the core tests silently V1 = Run all the core tests with minimal output V2 = Run all the core tests in debug mode You can also specify optional tests: N## = Go to sleep with interrupts of for ## seconds to test the HW NMI watchdog F## = Break at do_fork for ## iterations S## = Break at sys_open for ## iterations NOTE: that the do_fork and sys_open tests are mutually exclusive. To invoke the kgdb test suite from boot you use a kernel start argument as follows: kgdbts=V1 kgdbwait Or if you wanted to perform the NMI test for 6 seconds and do_fork test for 100 forks, you could use: kgdbts=V1N6F100 kgdbwait The test suite can also be invoked at run time with: echo kgdbts=V1N6F100 > /sys/module/kgdbts/parameters/kgdbts Or as another example: echo kgdbts=V2 > /sys/module/kgdbts/parameters/kgdbts When developing a new kgdb arch specific implementation or using these tests for the purpose of regression testing, several invocations are required. 1) Boot with the test suite enabled by using the kernel arguments "kgdbts=V1F100 kgdbwait" ## If kgdb arch specific implementation has NMI use "kgdbts=V1N6F100 2) After the system boot run the basic test. echo kgdbts=V1 > /sys/module/kgdbts/parameters/kgdbts 3) Run the concurrency tests. It is best to use n+1 while loops where n is the number of cpus you have in your system. The example below uses only two loops. ## This tests break points on sys_open while [ 1 ] ; do find / > /dev/null 2>&1 ; done & while [ 1 ] ; do find / > /dev/null 2>&1 ; done & echo kgdbts=V1S10000 > /sys/module/kgdbts/parameters/kgdbts fg # and hit control-c fg # and hit control-c ## This tests break points on do_fork while [ 1 ] ; do date > /dev/null ; done & while [ 1 ] ; do date > /dev/null ; done & echo kgdbts=V1F1000 > /sys/module/kgdbts/parameters/kgdbts fg # and hit control-c Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* | Driver for the Atmel on-chip SSC on AT32AP and AT91Hans-Christian Egtvedt2007-10-17
|/ | | | | | | | | | | | | | | | | | | | | | | | The Synchronous Serial Controller (SSC) on Atmel microprocessors are capable of tranceiving many frame based protocols, like I2S. Tested on the AT32AP7000/ATSTK1000. This driver is used in the ALSA sound driver for the AT73C213 external DAC on the ATSTK1000 development board for AVR32. This sound driver will be submitted soon. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 [akpm@linux-foundation.org: init spinlock at compile time] Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Acked-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Cc: David Brownell <david-b@pacbell.net> Cc: Andrew Victor <andrew@sanpeople.com> Cc: Patrice Vilchez <patrice.vilchez@rfo.atmel.com> Cc: Nicolas Ferre <nicolas.ferre@rfo.atmel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Remove the blink driverLinus Torvalds2007-07-04
| | | | | | | | | | | | | Yeah, we could have just disabled it, but there's work on a new one that isn't as fundamentally broken, so there really doesn't seem to be any point in keeping it around. The recent timer cleanup broke the only valid use, and when I say "valid", I obviously mean "totally broken". So it's not like it works, or really even can work in the current format that uses the unsafe "panic" LED blinking routines.. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* ACPI: ibm-acpi: rename driver to thinkpad-acpiHenrique de Moraes Holschuh2007-03-30
| | | | | | | | | | | | | | | | | | | | | Rename the ibm-acpi driver to thinkpad-acpi. ThinkPads are not even made by IBM anymore, so it is high time to rename the driver... The name thinkpad-acpi was used sometime ago by a thinkpad-specific hotkey driver by Erik Rigtorp, around the 2.6.8-2.6.10 time frame. The driver apparently never got merged into mainline (it did make some trips through -mm). ibm-acpi was merged soon after, making its debut in 2.6.10. The reuse of the thinkpad-acpi name shouldn't be a problem as far as user confusion goes, as Erik's thinkpad-acpi apparently didn't get widespread use in the Linux ThinkPad community and most hits for thinkpad-acpi in google point to ibm-acpi anyway. Erik, if you read this, please consider the reuse of the thinkpad-acpi name as a compliment to your effort to make ThinkPads more useful to all of us.
