* iio: generic_buffer: be helpful about enabling channelsLinus Walleij2015-08-161-0/+9
| | | | | | | | | | | | | | | | | | Currently if generic_buffer is invoked without first enabling any channels in scan_elements/*_en, it will fail unable to enable the buffer because bytes_per_datum inside the kernel will be zero if no channels are available. It is implied that the user of the program should enable channels manually or with a script before executing generic_buffer. Be more helpful by stopping execution if no enabled channels can be found, and print a helptext that will tell you what is wrong and what needs to be done.

Take 2 also includes a fix set that was too late for the 4.2 cycle. As we had a lot of tools and docs work in this set, I have broken those out into their own categories in this description. Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'. * Poll functions for both event chardev and the buffer one were returning negative error codes (via a positive value). * A recent change to lsiio adding some error handling that was wrong and stopped the tool working. * bmg160 was missing some dependencies in Kconfig * berlin2-adc had a misshandled register (wrote a value rather than a bitmap) New device support * TI opt3001 light sensor * TXC PA12 ALS and proximity sensor. * mcp3301 ADC support (in mcp320x driver) * ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors common support to allow different WHOAMI register addresses, devices with fixed scale and allow interrupt equiped magnetometers). * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver) * ADIS16266 gyro (in the adis16260 driver) * ADIS16137 gyro (in the adis16136 driver) New functionality * mmc35240 DT bindings. * Inverse unit conversion macros to aid handing of values written to sysfs attributes. Core cleanup * Forward declaration of struct iio_trigger to avoid a compile warning. Driver cleanup / fixes * mxs-lradc - Clarify which parts are supported. - Fix spelling erorrs. - Missing/extra includes - reorder includes - add datasheet name listings for all usable channels (to allow them to be bound by name from consumer drivers) * acpi-als - add some function prefixes as per general iio style. * bmc150_magn - replace a magic value with the existing define. * vf610 - determine possible sample frequencies taking into account the electrical characteristics (defining a minimum sample time) * dht11 - whitespace - additional docs - avoid mulitple assignments in one line - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick previously used for timing. * Fix all drivers that consider 0 a valid IRQ for historical reasons. * Export I2C module alias info where previously missing (to allow autoprobing) * Export OF module alias info where previously missing. * mmc35240 - switch some variables into arrays to improve readability. * mlx90614 - define some magic numbers for readability. * bmc150_magn - expand area locked by a mutex to cover all the use of the data->buffer. - use descriptive naming for a mask instead of a magic value. * berin2-adc - pass up an error code rather that a generic error - constify the iio_chan_spec - some other little tidy ups. * stk8312 - fix a dependency on triggered buffers in kconfig - add a check for invalid attribute values - improve error handling by returning error codes where possible and return immediately where relevant - rework macro defs to use GENMASK etc - change some variable types to reduce unnecessary casting - clean up code style - drop a local buffer copy for bulk reads and use the one in data->buffer instead. * adis16400 - the adis16448 gyroscope scale was wrong. * adis16480 - some more wrong scales for various parts. * adis16300 - has an undocumented product id and serial number registers so use them. * iio_simple_dummy - fix some wrong code indentation. * bmc150-accel - use the chip ID to detect the chip present rather than verifying the expected part was there. This was in response to a wrong ACPI entry on the WinBook TW100. * mma8452 - fix _get_hp_filter_index - drop a double include - pass up an error code rather than rewriting it - range check input values to attribute writes - register defs tidy up using GENMASK and reordering them to be easier to follow. - various coding style cleanups - put the Kconfig entry in the write place (alphabetically). Tools related * Tools cleanup - drop an explicity NULL comparison, some unnecessary braces, use the ARRAY_SIZE macro, send error messages to stderr instead of dropping them in the middle of normal output. * Fix tools to allow that scale and offset attributes are optional. * More tools fixes including allowing true 32bit data (previously an overflow prevented more than 31bits) * Drop a stray header guard that ended up in a c file. * Make calc_digits static as it isn't exported or in the header. * Set ci_array pointer to NULL after free as a protection against non safe usage of the tools core code. Also convert a double pointer to a single one as the extra level of indirection was unnecessary. Docs * DocBook introduction by Daniel Baluta. Glad we are beginning to draw together some more introductory docs to suplement the various tools / examples. * Drop bytes_per_datum sysfs attribute docs as it no longer exists. * A whole load of missing / fixing of kernel-doc for the core of IIO. * Document the trigger name sysfs attribute in the ABI docs. * Minor typos in the ABI docs related to power down modes.

As a result lsiio regresses and does not show any devices on my filesystem. Fix this by checking for only negative error codes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the the sensor data uses 32 bits out of 32, generic_buffer prints the value 0 for all data read. In this case, the mask is shifted 32 bits, which is beyond the size of an integer. This will lead to the mask always being 0. Before printing, the mask is applied to the raw value, thus generating a final value of 0. Fix the mask by shifting a 64 bit value instead of an integer.

But implementation didn't take into account the fact that LD is a pre-defined variable in GNU Make. I.e. it is always defined. Which means there's no point to check "LD ?= ..." because it will never succeed. And so LD will be either that explicitly passed to make like this: ------->8------- make LD=path_to_my_ld ... ------->8------- or default value, which is host's "ld". Latter leads to failure of cross-linkage because instead of cross linker "$(CROSS_COMPILE)ld" host's "ld" is used. Fortunately there's a way to do correct substitution of $(CROSS_COMPILE)ld with user defined LD on command-line. As a reference was used implementation in "tools/lib/traceevent/Makefile". Build tested for x86_64 and ARC. Thanks Jiri for this hint.

But then, in: commit 268397cb2a47 Author: Namhyung Kim <namhyung@kernel.org> Date: Tue Apr 22 14:49:31 2014 +0900 perf top/tui: Update nr_entries properly after a filter is applied We don't take into account entries that were filtered in perf_event__preprocess_sample() and friends, which leads to inconsistency in the browser seek routines, that expects the number of hist_entry->filtered entries to match what it thinks is the number of unfiltered, browsable entries. So, for instance, when we do: perf top --symbols ___non_existent_symbol___ the hist_browser__nr_entries() routine thinks there are no filters in place, uses the hists->nr_entries but all entries are filtered, leading to a segfault. Tested with: perf top --symbols malloc,free --percentage=relative Freezing, by pressing 'f', at any time and doing the math on the percentages ends up with 100%, ditto for: perf top --dsos libpthread-2.20.so,libxul.so --percentage=relative Both were segfaulting, all fixed now. More work needed to do away with checking if filters are in place, we should just use the nr_non_filtered_samples counter, no need to conditionally use it or hists.nr_filter, as what the browser does is just show unfiltered stuff. An audit of how it is being accounted is needed, this is the minimal fix.

And besides that, we need to zero out those extra fields, that sometimes may not get filled, like when we couldn't care less about the comms, since we don't need those, but since we will try freeing it at thread_map__delete(), we better fix it. That is why a thread_map__realloc() was provided. But that method wasn't used in thread_map__new_by_uid(), fix it.

Core and tools new stuff * Allow explicit flush of hardware fifo by using an non blocking read. This is needed to support some of the Android requirements for HW fifo devices - also makes sense generally and clarifies a corner of the ABI. * Add some missing modifier names. Mostly these exist for weird and wonderful event types, but should still be present in the name array. * Update iio_event_monitor to cope with new channel types. * generic_buffer gains support for single byte scan elements (no idea how this never got implemented before!) New device support * ROHM rpr0521 light and proximity sensor driver. * bmc150 gains bmc156 support. * ms5611 gains ms5607 temperature and pressure sensor support. Driver functionality * inv-mpu - add scale_available attributes to aid userspace in configuring these devices. * isl29125 - add scale_available attributes. * stk8ba50 - sampling frequency control, triggered buffer support. * stk8312 - sampling frequency control, triggered buffer support. * cc10001 - ensure ADC powered up at probe time if shared by non linux running CPUs. * bmc150-magn - decouple the buffer and trigger allowing other triggers to be used to drive this device's sampling. Documentation * Add some previously missed *scale_available attributes to the ABI docs. Cleanups * Clarify some crazy naming in iio_triggered_buffer_setup that seems to have somehow ended up backwards (dates back a long way). Avoid the top half and bottom half naming entirely given we are how dealing with a handler and a thread in all cases. * Tools cleanup including coding style, variable naming improvements, also a new sanity check on a full event having been read. * stk8ba50 - replace the scale table with a struct for clarity. Also suspend the sensor if an error occurs in init. * hid-sensor-prox - drop uneeded line break. * mma9551 - use size in words for word read / write avoiding accidental sending of an odd number of bytes. * mma9553 - fix code alignment and document the use of a mutex. * light/Kconfig - typo fix in commment. * cm3323 - don't eat an error value, replace an unneeded local variable with a generic local variable with the same use, add some blank lines for clarity. * pressure/Kconfig - typo in Measurement Specialties name. * bmc150-accel - actually use a mask definition rather than repeating the value inline, code style cleanup. * adc/Kconfig - general help description cleanup. * ssp_sensors - drop redundant spi driver bus initialization (done in the spi core) * tmp006 - use genmask rather than hand generated masks. * ms5611 - drop IIO_CHAN_INFO_SCALE as this driver provides a processed output and as such the read only scale adds nothing useful. * kxcjk-1013, adf4350, dummy - drop unwanted blank lines. * Drop all owner assignments from i2c_drivers and this is done in the i2c core.
