vme: add vme_init_bridge for common bridge init

2016-05-01T21:00:00+00:00

Consolidate vme_bridge structure setup that every bridge was required to do itself. This came about because .irq_mtx is only used within the VME core, but was required to be setup externally. This returns the structure passed in to support shorthand like this: bridge = vme_init_bridge(&priv->bridge); Signed-off-by: Aaron Sierra Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: trivial spelling and capitalization fixes

2016-05-01T21:00:00+00:00

Fix a typo in the spurious interrupt warning and consistently capitalize VME, PCI, and DMA acronyms. Signed-off-by: Aaron Sierra Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: print unhandled VME access errors

2015-10-04T18:50:57+00:00

This will enable error messages for accesses done through mmap. Signed-off-by: Dmitry Kalinkin Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: change bus error handling scheme

2015-10-04T18:50:57+00:00

The current VME bus error handler adds errors to the bridge error list. vme_master_{read,write} then traverses that list to look for relevant errors. Such scheme didn't work well for accesses going through vme_master_mmap because they would also allocate a vme_bus_error, but have no way to do vme_clear_errors call to free that memory. This changes the error handling process to be other way around: now vme_master_{read,write} defines a window in VME address space that will catch possible errors. VME bus error interrupt only traverses these windows and marks those that had errors in them. Signed-off-by: Dmitry Kalinkin Cc: Igor Alekseev Signed-off-by: Greg Kroah-Hartman

vme: include address space in error filtering

2015-10-04T18:50:57+00:00

Also changes vme_bus_error_handler to take generic address modifier code instead of raw contents of a device-specific attribute register. Signed-off-by: Dmitry Kalinkin Cc: Igor Alekseev Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: move tsi148 error handling into VME subsystem

2015-10-04T18:50:57+00:00

Error handling code found in tsi148 is not device specific. In fact it already relies on shared vme_bus_error struct and vme_bridge.vme_errors field. The other bridge driver could reuse this code if it is shared. This introduces a slight behavior change: vme error message won't be triggered in a rare case when err_chk=1 and kmalloc fails.

staging: vme: mmap() support for vme_user

2015-03-07T01:03:22+00:00

We also make sure that user won't be able to reconfigure the window while it is mmap'ed. Signed-off-by: Dmitry Kalinkin Cc: Martyn Welch Cc: Igor Alekseev Signed-off-by: Greg Kroah-Hartman

vme: fix misspelling of current function in string

2015-01-12T13:04:12+00:00

Replace a misspelled function name by %s and then __func__. This is the get function, not the set function, as was indicated by the string. This was done using Coccinelle, including the use of Levenshtein distance, as proposed by Rasmus Villemoes. Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman
