| | | | | | | | | | | | | | | | In preparation for moving the queue pair data structure to rdmavt the members of the driver specific queue pairs which are not common need to be pushed off to a private driver structure. This structure will be available in the queue pair once moved to rdmavt as a void pointer. This patch while not adding a lot of value in and of itself is a prerequisite to move the queue pair out of the drivers and into rdmavt. The driver specific, private queue pair data structure should condense as more of the send side code moves to rdmavt.

As well as enabling the new feature by tying the new function with the PSM API, it also cleans up the old unneeded code, data structure members, and variables. Due to difference in operation and information, the tracing functions related to expected receives had to be changed. This patch include these changes. The tracing function changes could not be split into a separate commit without including both tracing variants at the same time. This would have caused other complications and ugliness.

* staging/hfi1: Add TID entry program function bodyMitko Haralanov2016-02-291-4/+259
| | | | | | | | | | | | | | | | | | | The previous patch in the series added the free/invalidate function bodies. Now, it's time for the programming side. This large function takes the user's buffer, breaks it up into manageable chunks, allocates enough RcvArray groups and programs the chunks into the RcvArray entries in the hardware. With this function, the TID caching functionality is implemented. However, it is still unused. The switch will come in a later patch in the series, which will remove the old functionality and switch the driver over to TID caching.

TID groups (or RcvArray groups) are groups of TID/RcvArray entries organized in sets of 8 and aligned on cacheline boundaries. The TID/RcvArray entries are managed in this way to make taking advantage of write-combining easier - each group is a entire cacheline. rcv_array_wc_fill() is provided to allow of generating writes to TIDs which are not currently being used in order to cause the flush of the write-combining buffer.

A second set will follow shortly with ones that are. * core in kernel interfaces - fix a possible NULL dereference that is a theoretical possibility via odd usage of iio_channel_release. Pretty much a hardening of the interface, but observed in the wild with the twl4030_charger driver. * acpi-als - report the data as processed as it is in lux. This fixes a wrong use of the IIO ABI. However, old _raw version retained to avoid breaking any userspace in the wild that is relying on that (none known but it doesn't hurt us much to retain it) * ade7753 - fix some error handling to avoid use of unitialized data. * ltr501 - use a signed return type for ltr501_match_samp_freq so as to allow returning of an error code. * mcp4725 - set name field of struct iio_dev to ensure the sysfs name attribute doesn't give NULL. * mpl115 - temperature offset sign is wrong. * stk8ba50 - IIO_TRIGGER dependency added * ti_am335x_adc - Label buffer as a software buffer. It's actually a hybrid of a true hardware buffer feeding a kfifo, but the meaning of these fields has changed a little recently and in this case it should be labeled a software buffer ensure it is allowed to use the kfifo. * vf610_adc - HAS_IOMEM dependency

However, the ade7753_stop_device() and ade7753_reset() functions use the returned data without checking for an error condition first. Gcc detects this as a possible bug and warns about it: drivers/staging/iio/meter/ade7753.c: In function 'ade7753_remove': drivers/staging/iio/meter/ade7753.c:348:6: error: 'val' may be used uninitialized in this function [-Werror=maybe-uninitialized] val |= BIT(4); /* AD converters can be turned off */ ^ drivers/staging/iio/meter/ade7753.c:345:6: note: 'val' was declared here u16 val; ^ drivers/staging/iio/meter/ade7753.c: In function 'ade7753_probe': drivers/staging/iio/meter/ade7753.c:222:6: error: 'val' may be used uninitialized in this function [-Werror=maybe-uninitialized] In both cases, we can avoids the warning by checking the return code before using the data.
