* VMware balloon: stop locking pages when hypervisor tells us enoughDmitry Torokhov2011-01-13
| | | | | | | | | | | | | | | | | | | When hypervisor decides to decrease target balloon size while the balloon driver tries to lock pages hypervisor may respond with VMW_BALLOON_PPN_NOTNEEDED. Use this data and immediately stop reserving pages and wait for the next update cycle to fetch new target instead of continuing trying to lock pages until size of refused list grows above VMW_BALLOON_MAX_REFUSED (16) pages. As a result the driver stops bothering the hypervisor with its attempts to lock more pages that are not needed anymore. Most likely next order from hypervisor will be to reduce ballon size anyway. It is a small optimization. Signed-off-by: Dmitry Torokhov <dtor@vmware.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* w1: DS2423 counter driver and documentationMika Laitio2011-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a 1-wire/w1 DS2423 slave driver for reading the values from all 4 counters available DS2423 devices by using standard w1_slave file. In ds2423 the counters are tied to ram pages 12-15 in and each of those ram-pages. Each of these counter values (and asoociated ram page values) are represented as a own line in w1_slave file. Driver has been tested on mips and x86. usage example: cat /sys/bus/w1/devices/1d-00000009b964/w1_slave 00 02 00 00 00 00 00 00 00 6d 38 00 ff ff 00 00 fe ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 02 00 00 00 00 00 00 00 e0 1f 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=2 00 5a 0e 5f 18 00 00 00 00 0b 28 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff 00 00 ff ff crc=YES c=408882778 00 05 00 00 00 00 00 00 00 8d 39 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff crc=YES c=5 Patch includes also the documentation.

* pps: add parallel port PPS clientAlexander Gordeev2011-01-13
| | | | | | | | | | | | | | | | | | | | | | Add parallel port PPS client. It uses a standard method for capturing timestamps for assert edge transitions: getting a timestamp soon after an interrupt has happened. This is not a very precise source of time information due to interrupt handling delays. However, timestamps for clear edge transitions are much more precise because the interrupt handler continuously polls hardware port until the transition is done. Hardware port operations require only about 1us so the maximum error should not exceed this value. This was my primary goal when developing this client. Clear edge capture could be disabled using clear_wait parameter.

* ntp: add hardpps implementationAlexander Gordeev2011-01-13
| | | | | | | | | | | | | | | | | | | | | This commit adds hardpps() implementation based upon the original one from the NTPv4 reference kernel code from David Mills. However, it is highly optimized towards very fast syncronization and maximum stickness to PPS signal. The typical error is less then a microsecond. To make it sync faster I had to throw away exponential phase filter so that the full phase offset is corrected immediately. Then I also had to throw away median phase filter because it gives a bigger error itself if used without exponential filter. Maybe we will find an appropriate filtering scheme in the future but it's not necessary if the signal quality is ok.

* pps: make idr lock a mutex and protect idr_pre_getAlexander Gordeev2011-01-13
| | | | | | | | | | | | | Now pps_idr_lock is never used in interrupt context so we can replace spin_lock_irq/spin_unlock_irq with plain spin_lock/spin_unlock.

* pps: fix race in PPS_FETCH handlerAlexander Gordeev2011-01-13
| | | | | | | | | | | | | | | | | | | | | There was a race in PPS_FETCH ioctl handler when several processes want to obtain PPS data simultaneously using sleeping PPS_FETCH. They all sleep most of the time in the system call. With the old approach when the first process waiting on the pps queue is waken up it makes new system call right away and zeroes pps->go. So other processes continue to sleep. This is a clear race condition because of the global 'go' variable. With the new approach pps->last_ev holds some value increasing at each PPS event. PPS_FETCH ioctl handler saves current value to the local variable at the very beginning so it can safely check that there is a new event by just comparing both variables.

* cs5535: deprecate older cs5535_gpio driverAndres Salomon2011-01-13
| | | | | | | | | | | | | | | The newer drivers/gpio/cs5535-gpio.c replaces drivers/misc/cs5535_gpio.c. The new driver has been in the tree for a little while, and has received some testing; it's time to mark the old one as deprecated. I'm thinking removal around 2.6.40 would be good, provided we're not missing critical functionality in the newer driver.

* drivers/staging/olpc_dcon: convert to new cs5535 gpio APIAndres Salomon2011-01-13
| | | | | | | | | | | | | | | | Drop the old geode_gpio crud, as well as the raw outl() calls; instead, use the Linux GPIO API where possible, and the cs5535_gpio API in other places. Note that we don't actually clean up the driver properly yet (once loaded, it always remains loaded). That'll come later.. This patch is necessary for building the driver.

* drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO ↵Andres Salomon2011-01-13
| | | | | | | | | | | | | | | | | | | | functionality This adds (well, re-adds actually) handling for events/IRQs through cs5535 GPIOs. In the wild and wooly world of CS5535, setup_event() is for assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the pair to trigger IRQs. These should really only be used in highly platform-specific drivers (such as OLPC's DCON driver). Sadly, because set_irq() uses MSRs, this causes the driver to become X86-specific.
