sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Fix device delete child function.

2016-10-17T10:20:38Z

When detaching device trees parent devices must be detached prior to detaching its children. This is because parent devices can have pointers to the child devices in their softcs which are not invalidated by device_delete_child(). This can cause use after free issues and panic(). Device drivers implementing trees, must ensure its detach function detaches or deletes all its children before returning. While at it remove now redundant device_detach() calls before device_delete_child() and device_delete_children(), mostly in the USB controller drivers.

Convert rman to use rman_res_t instead of u_long

2016-01-27T02:23:54Z

Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

Add MSI support to puc(9)

2014-03-13T15:57:25Z

Add support for MSI interrupts in the puc(9) driver. By default the driver will prefer MSI interrupts to legacy interrupts. A tunable, hw.puc.msi_disable, has been added to force the allocation of legacy interrupts. Reviewed by: jhb@ MFC after: 2 weeks Sponsored by: Sandvine Inc.

Fix interrupt handling. It started off broken and grew worse over time.

2009-12-11T03:08:07Z

The rewrite of the interrupt handler includes: o loop until all pending interrupts are handled. This closes a race condition. o count the number of interrupt sources we handled so that we can properly return FILTER_HANDLED or FILTER_STRAY when we break out of the loop. o When matching the interrupt source to the devices that have that source pending, check only from the set of devices we found to have a pending interrupt.
