| * mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEANMike Dunn2012-05-141-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drivers' _read() method, absent an error, returns a non-negative integer indicating the maximum number of bit errors that were corrected in any one region comprising an ecc step. MTD returns -EUCLEAN if this is >= bitflip_threshold, 0 otherwise. If bitflip_threshold is zero, the comparison is not made since these devices lack ECC and always return zero in the non-error case (thanks Brian)¹. Note that this is a subtle change to the driver interface. This and the preceding patches in this set were tested with ubi on top of the nandsim and docg4 devices, running the ubi test io_basic from mtd-utils. ¹ http://lists.infradead.org/pipermail/linux-mtd/2012-March/040468.html Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Acked-by: Robert Jarzmik <robert.jarzmik@free.fr> Acked-by: Brian Norris <computersforpeace@gmail.com> Ivan Djelic <ivan.djelic@parrot.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
| * mtd: bitflip_threshold added to mtd_info and sysfsMike Dunn2012-05-141-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An element 'bitflip_threshold' is added to struct mtd_info, and also exposed as a read/write variable in sysfs. This will be used to determine whether or not mtd_read() returns -EUCLEAN or 0 (absent a hard error). If the driver leaves it as zero, mtd will set it to a default value of ecc_strength. This v2 adds the line that propagates bitflip_threshold from the master to the partitions - thanks Ivan¹. ¹ http://lists.infradead.org/pipermail/linux-mtd/2012-April/040900.html Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

This patch adds the following APIs- fcoe_ctlr_device_add fcoe_ctlr_device_delete fcoe_fcf_device_add fcoe_fcf_device_delete They allow the LLD to expose the FCoE ENode Controller and any discovered FCFs (Fibre Channel Forwarders, e.g. FCoE switches) to the user. Each of these new devices has their own bus_type so that they are grouped together for easy lookup from a user space application. Each new class has an attribute_group to expose attributes for any created instances. The attributes are- fcoe_ctlr_device * fcf_dev_loss_tmo * lesb_link_fail * lesb_vlink_fail * lesb_miss_fka * lesb_symb_err * lesb_err_block * lesb_fcs_error fcoe_fcf_device * fabric_name * switch_name * priority * selected * fc_map * vfid * mac * fka_peroid * fabric_state * dev_loss_tmo A device loss infrastructre similar to the FC Transport's is also added by this patch. It is nice to have so that a link flapping adapter doesn't continually advance the count used to identify the discovered FCF. FCFs will exist in a "Disconnected" state until either the timer expires or the FCF is rediscovered and becomes "Connected." This patch generates a few checkpatch.pl WARNINGS that I'm not sure what to do about. They're macros modeled around the FC Transport attribute building macros, which have the same 'feature' where the caller can ommit a cast in the argument list and no cast occurs in the code. I'm not sure how to keep the code condensed while keeping the macros. Any advice would be appreciated.

Writing a wakelock name and optionally a timeout to the wake_lock file causes the wakelock whose name was written to be acquired (it is created before is necessary), optionally with the given timeout. Writing the name of a wakelock to wake_unlock causes that wakelock to be released. Implement an analogous interface for user space using wakeup sources. Add the /sys/power/wake_lock and /sys/power/wake_unlock files allowing user space to create, activate and deactivate wakeup sources, such that writing a name and optionally a timeout to wake_lock causes the wakeup source of that name to be activated, optionally with the given timeout. If that wakeup source doesn't exist, it will be created and then activated. Writing a name to wake_unlock causes the wakeup source of that name, if there is one, to be deactivated. Wakeup sources created with the help of wake_lock that haven't been used for more than 5 minutes are garbage collected and destroyed. Moreover, there can be only WL_NUMBER_LIMIT wakeup sources created with the help of wake_lock present at a time. The data type used to track wakeup sources created by user space is called "struct wakelock" to indicate the origins of this feature.

It consists of a new sysfs attribute, /sys/power/autosleep, that can be written one of the strings returned by reads from /sys/power/state, an ordered workqueue and a work item carrying out the "suspend" operations. If a string representing the system's sleep state is written to /sys/power/autosleep, the work item triggering transitions to that state is queued up and it requeues itself after every execution until user space writes "off" to /sys/power/autosleep. That work item enables the detection of wakeup events using the functions already defined in drivers/base/power/wakeup.c (with one small modification) and calls either pm_suspend(), or hibernate() to put the system into a sleep state. If a wakeup event is reported while the transition is in progress, it will abort the transition and the "system suspend" work item will be queued up again. Signed-off-by: Rafael J.

This removes the struct wakeup_source's hit_cout field, which is very rough and therefore not very useful, and adds two new fields, wakeup_count and expire_count. The first one tracks how many times the wakeup source is activated with events_check_enabled set (which roughly corresponds to the situations when a system power transition to a sleep state is in progress and would be aborted by this wakeup source if it were the only active one at that time) and the second one is the number of times the wakeup source has been activated with a timeout that expired. Additionally, the last_time field is now updated when the wakeup source is deactivated too (previously it was only updated during the wakeup source's activation), which seems to be what Android does with the analogous counter for wakelocks.

There's various problems with the code as it stands today, first and foremost the user interface which is bound to topology levels and has multiple values per level. This results in a state explosion which the administrator or distro needs to master and almost nobody does. Furthermore large configuration state spaces aren't good, it means the thing doesn't just work right because it's either under so many impossibe to meet constraints, or even if there's an achievable state workloads have to be aware of it precisely and can never meet it for dynamic workloads. So pushing this kind of decision to user-space was a bad idea even with a single knob - it's exponentially worse with knobs on every node of the topology. There is a proposal to replace the user interface with a single 3 state knob: sched_balance_policy := { performance, power, auto } where 'auto' would be the preferred default which looks at things like Battery/AC mode and possible cpufreq state or whatever the hw exposes to show us power use expectations - but there's been no progress on it in the past many months. Aside from that, the actual implementation of the various knobs is known to be broken. There have been sporadic attempts at fixing things but these always stop short of reaching a mergable state. Therefore this wholesale removal with the hopes of spurring people who care to come forward once again and work on a coherent replacement.

For example, one 30-pin port may inhabit a USB cable, an HDMI cable, and a mic. Thus, one switch device requires multiple state bits each representing a type of cable. For such purpose, we use the 32bit state variable; thus, up to 32 different type of cables may be defined for a switch device. The list of possible cables is defined by the array of cable names in the switch_dev struct given to the class.
