+Hall sensor driver
|
|
+
|
|
+Hall sensor is a switch. It senses magnetic field change and trigger interrupts to cpu.
|
|
+
|
|
+Required properties:
|
|
+
|
|
+ - compatible : Should be "hall-switch".
|
|
+ - pinctrl-names : Pinctrl configuration names of this sensor driver.
|
|
+ Should be "default".
|
|
+ - interrupt-parent : Parent of interrupt.
|
|
+ - interrupts : Hall Sensor interrupts to indicate new data ready or events.
|
|
+ - vddio-supply : Analog power supply needed to power device.
|
|
+ - linux,gpio-int : Irq gpio which is to provide interrupts to host.
|
|
+ - linux,min-uv : Device required minimum voltage.
|
|
+ - linux,max-uv : Device required max voltage.
|
|
+
|
|
+Optional properties:
|
|
+
|
|
+ - linux,wakeup : Boolean to select interrupt wakeup or not, if this property is defined
|
|
+ device will wakeup system.
|
|
+
|
|
+Example:
|
|
+ &soc {
|
|
+ hall {
|
|
+ compatible = "hall-switch";
|
|
+ pinctrl-names = "default";
|

+ - reg : i2c slave address of the device.
|
|
+ - pinctrl-names : Pinctrl configuration names of this sensor driver.
|
|
+ Should be "default".

+ - vio-supply : Digital IO power supply needed for IO and I2C.
|
|
+ - bosch,init-interval : Initial data polling interval in millisecond.
|
|
+ - bosch,place : The placing of the accelerometer on board. There are 8
|
|
+ patterns of placing described as below:
|
|
+ 0: 1st pin is right down
|
|
+ 1: 1st pin is left down
|
|
+ 2: 1st pin is left top
|
|
+ 3: 1st pin is right top
|
|

|
+ - bosch,gpio-int2 : 2nd irq gpio which is to provide interrupts
|
|
+ to host.
|
|
+ - bosch,use-interrupt : Use device interrupt to trigger data acquisition
|
|
+ instead of polling data.
|
|
+ - bosch,use-int2 : Map interrupt signal to 2nd interrupt pin of device.
|
|
+ If this property is defined, data ready, fifo full and
|
|
+ other event will trigger level change on interrupt pin2
|
|
+ instead of interrupt pin1.
|
|

|
|
+ * how well that works in practice, somebody might be relying on it.
|
|
+ *
|
|
+ * At the time we make a sample, we don't know whether the consumer is

|
|
- * The SMP TLB coherency scheme we use works as follows:
|
|
- *
|
|
- * 1) mm->cpu_vm_mask is a bit mask of which cpus an address
|
|
- * space has (potentially) executed on, this is the heuristic
|
|
- * we use to avoid doing cross calls.
|
|
- *
|
|
- * Also, for flushing from kswapd and also for clones, we
|
|
- * use cpu_vm_mask as the list of cpus to make run the TLB.
|
|
- *
|
|
- * 2) TLB context numbers are shared globally across all processors
|
|
- * in the system, this allows us to play several games to avoid
|
|
- * cross calls.
|
|
- *
|
|
- * One invariant is that when a cpu switches to a process, and
|
|
- * that processes tsk->active_mm->cpu_vm_mask does not have the
|
|
- * current cpu's bit set, that tlb context is flushed locally.
|
|
- *
|
|
- * If the address space is non-shared (ie. mm->count == 1) we avoid
|
|
- * cross calls when we want to flush the currently running process's
|
|
- * tlb state. This is done by clearing all cpu bits except the current
|
|
- * processor's in current->mm->cpu_vm_mask and performing the
|
|
- * flush locally only. This will force any subsequent cpus which run
|
|
- * this task to flush the context from the local tlb if the process
|
|
- * migrates to another cpu (again).
|
|
- *
|
|
- * 3) For shared address spaces (threads) and swapping we bite the
|
|
- * bullet for most cases and perform the cross call (but only to
|
|
- * the cpus listed in cpu_vm_mask).
|
|
- *
|
|
- * The performance gain from "optimizing" away the cross call for threads is
|
|
- * questionable (in theory the big win for threads is the massive sharing of
|
|
- * address space state across processors).

|

+ * Garbage collection of unix sockets starts by selecting a set of

|
+ * candidate sockets which have reference only from being in flight
|
|
+ * (total_refs == inflight_refs). This condition is checked once during

|
+ * that non-candidates can later be ignored. While inflight_refs is
|
|
+ * protected by unix_gc_lock, total_refs (file count) is not, hence this
|
|
+ * is an instantaneous decision.
|
|
+ *
|
|
+ * Once a candidate, however, the socket must not be reinstalled into a
|
|
+ * file descriptor while the garbage collection is in progress.
|
|
+ *
|
|
+ * If the above conditions are met, then the directed graph of
|
|

|
|
+ *
|
|
+ * Any operations that changes the file count through file descriptors
|
|
+ * (dup, close, sendmsg) does not change the graph since candidates are
|
|
+ * not installed in fds.
|
|
+ *
|
|
+ * Dequeing a candidate via recvmsg would install it into an fd, but
|
|
+ * that takes unix_gc_lock to decrement the inflight count, so it's
|
|
+ * serialized with garbage collection.
|
|
+ *
|
|
+ * MSG_PEEK is special in that it does not change the inflight count,
|
|
+ * yet does install the socket into an fd. The following lock/unlock
|
|
+ * pair is to ensure serialization with garbage collection. It must be
|
|
+ * done between incrementing the file count and installing the file into
|
|
+ * an fd.
|
|
+ *
|
|
+ * If garbage collection starts after the barrier provided by the
|
|
+ * lock/unlock, then it will see the elevated refcount and not mark this
|
|
+ * as a candidate. If a garbage collection is already in progress
|
|
+ * before the file count was incremented, then the lock/unlock pair will
|
|
+ * ensure that garbage collection is finished before progressing to
|
|
+ * installing the fd.
