2011-01-13VMware balloon: stop locking pages when hypervisor tells us enoughDmitry Torokhov1-5/+8
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>
2011-01-13w1: DS2423 counter driver and documentationMika Laitio4-0/+179
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.

2011-01-13pps: add parallel port PPS clientAlexander Gordeev3-0/+266
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.

2011-01-13ntp: add hardpps implementationAlexander Gordeev1-0/+9
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.

2011-01-13pps: make idr lock a mutex and protect idr_pre_getAlexander Gordeev1-8/+11
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. But there is also a potential race condition when someone can steal an id which was allocated by idr_pre_get before it is used. So convert spin lock to mutex and protect the whole id generation process.

2011-01-13pps: move idr stuff to pps.cAlexander Gordeev2-54/+52
Since now idr is only used to manage char device id's and not used in kernel API anymore it should be moved to pps.c. This also makes it possible to release id only at actual device freeing so nobody can register a pps device with the same id while our device is not freed yet.

2011-01-13pps: convert printk/pr_* to dev_*Alexander Gordeev4-21/+26
Since we now have direct pointers to struct pps_device everywhere it's easy to use dev_* functions to print messages instead of plain printks. Where dev_* cannot be used printks are converted to pr_*.

2011-01-13pps: access pps device by direct pointerAlexander Gordeev4-144/+73
Using device index as a pointer needs some unnecessary work to be done every time the pointer is needed (in irq handler for example). Using a direct pointer is much more easy (and safe as well).

2011-01-13pps: fix race in PPS_FETCH handlerAlexander Gordeev2-5/+9
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.

Change the way how switchid value is set. Local counter variable does not provide unified way to identify switch devices in a system with multiple processors. Using local counter leads to the situation when the same RIO switch has different switch ID for each processor. Replacing local counter with unique portion of the Component Tag provides unified reference to the switch by every processor in the system.
