bc677ff42e81bbf78308a7b66cf7b63b0f5c26b0 adds a device-tree property to specify that an external watchdog reset is used to reset other portions of the board and not just the IMX6 SoC. This adds the property to the proper watchdog as well as the pinmux for the Gateworks Ventana boards that use this external watchdog reset to reset the PMIC which will reset all the PMIC power rails and not just a chip-level IMX6 reset. This helps to work around various system issues that can cause a hang when coming out of reset. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2016-08-07block: rename bio bi_rw to bi_opfJens Axboe51-157/+158
Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower portion and the op code in the higher portions. This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.

2016-08-07block/mm: make bdev_ops->rw_page() take a bool for read/writeJens Axboe11-53/+51
Commit abf545484d31 changed it from an 'rw' flags type to the newer ops based interface, but now we're effectively leaking some bdev internals to the rest of the kernel. Since we only care about whether it's a read or a write at that level, just pass in a bool 'is_write' parameter instead. Then we can also move op_is_write() and friends back under CONFIG_BLOCK protection. Reviewed-by: Mike Christie <mchristi@redhat.com> Signed-off-by: Jens Axboe <axboe@fb.com>

2016-08-05ntb_test: Add a selftest script for the NTB subsystemLogan Gunthorpe2-0/+423
This script automates testing doorbells, scratchpads and memory windows for an NTB device. It can be run locally, with the NTB looped back to the same host or use SSH to remotely control the second host. In the single host case, the script just needs to be passed two arguments: a PCI ID for each side of the link. In the two host case the -r option must be used to specify the remote hostname (which must be SSH accessible and should probably have ssh-keys exchanged). A sample run looks like this: $ sudo ./ntb_test.sh 0000:03:00.1 0000:83:00.1 -p 29 Starting ntb_tool tests...

2016-08-05ntb_perf: clear link_is_up flag when the link goes down.Logan Gunthorpe1-19/+9
When the link goes down, the link_is_up flag did not return to false. This could have caused some subtle corner case bugs when the link goes up and down quickly. Once that was fixed, there was found to be a race if the link was brought down then immediately up. The link_cleanup work would occasionally be scheduled after the next link up event. This would cancel the link_work that was supposed to occur and leave ntb_perf in an unusable state. To fix this we get rid of the link_cleanup work and put the actions directly in the link_down event.

2016-08-05ntb_pingpong: Add a debugfs file to get the ping countLogan Gunthorpe1-1/+61
This commit adds a debugfs 'count' file to ntb_pingpong. This is so testing with ntb_pingpong can be automated beyond just checking the logs for pong messages. The count file returns a number which increments every pong. The counter can be cleared by writing a zero.

2016-08-05ntb_tool: Add link status and files to debugfsLogan Gunthorpe1-0/+92
In order to more successfully script with ntb_tool it's useful to have a link file to check the link status so that the script doesn't use the other files until the link is up. This commit adds a 'link' file to the debugfs directory which reads boolean (Y or N) depending on the link status. Writing to the file change the link state using ntb_link_enable or ntb_link_disable. A 'link_event' file is also provided so an application can block until the link changes to the desired state. If the user writes a 1, it will block until the link is up. If the user writes a 0, it will block until the link is down.

2016-08-05ntb_tool: Postpone memory window initialization for the userLogan Gunthorpe1-138/+228
In order to make the interface closer to the raw NTB API, this commit changes memory windows so they are not initialized on link up. Instead, the 'peer_trans*' debugfs files are introduced. When read, they return information provided by ntb_mw_get_range. When written, they create a buffer and initialize the memory window. The value written is taken as the requested size of the buffer (which is then rounded for alignment). Writing a value of zero frees the buffer and tears down the memory window translation. The 'peer_mw*' file is only created once the memory window translation is setup by the user. Additionally, it was noticed that the read and write functions for the 'peer_mw*' files should have checked for a NULL pointer.

2016-08-05ntb_perf: Wait for link before running testLogan Gunthorpe1-1/+4

2016-08-05ntb_perf: Return results by reading the run fileLogan Gunthorpe1-12/+55
Instead of having to watch logs, allow the results to be retrieved by reading back the run file. This file will return "running" when the test is running and nothing if no tests have been run yet. It returns 1 line per thread, and will display an error message if the corresponding thread returns an error. With the above change, the pr_info calls that returned the results are then changed to pr_debug calls.

2016-08-05ntb_perf: Improve thread handling to increase robustnessLogan Gunthorpe1-48/+76
This commit accomplishes a few things: 1) Properly prevent multiple sets of threads from running at once using a mutex. Lots of race issues existed with the thread_cleanup. 2) The mutex allows us to ensure that threads are finished before tearing down the device or module. 3) Don't use kthread_stop when the threads can exit by themselves, as this is counter-indicated by the kthread_create documentation. Threads now wait for kthread_stop to occur. 4) Writing to the run file now blocks until the threads are complete. The test can then be safely interrupted by a SIGINT. Also, while I was at it: 5) debugfs_run_write shouldn't return 0 in the early check cases as this could cause debugfs_run_write to loop undesirably.

2016-08-05ntb_perf: Schedule based on time not on performanceLogan Gunthorpe1-2/+4
When debugging performance problems, if some issue causes the ntb hardware to be significantly slower than expected, ntb_perf will hang requiring a reboot because it only schedules once every 4GB.

2016-08-05ntb_transport: Check the number of spads the hardware supportsLogan Gunthorpe2-4/+13
I'm working on hardware that currently has a limited number of scratchpad registers and ntb_ndev fails with no clue as to why. I feel it is better to fail early and provide a reasonable error message then to fail later on. The same is done to ntb_perf, but it doesn't currently require enough spads to actually fail. I've also removed the unused SPAD_MSG and SPAD_ACK enums so that MAX_SPAD accurately reflects the number of spads used.
