Giffuni pfg@FreeBSD.org 2017-11-27T14:52:40Z urn:sha1:718cf2ccb9956613756ab15d7a0e28f2c8e91cab 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. Replace some more default range checks with RMAN_IS_DEFAULT_RANGE(). 2016-03-02T03:26:56Z Justin Hibbits jhibbits@FreeBSD.org 2016-03-02T03:26:56Z urn:sha1:82ed3cb0e4bf60f58b13368aa3a4a4f7e7ff9a57 This is a follow-on to r295832. Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere(). 2016-02-27T03:38:01Z Justin Hibbits jhibbits@FreeBSD.org 2016-02-27T03:38:01Z urn:sha1:c47476d7e6801deffc8b3c057d0fbf7d2335a0c2 Most calls to bus_alloc_resource() use "anywhere" as the range, with a given count. Migrate these to use the new bus_alloc_resource_anywhere() API. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D5370 Convert rman to use rman_res_t instead of u_long 2016-01-27T02:23:54Z Justin Hibbits jhibbits@FreeBSD.org 2016-01-27T02:23:54Z urn:sha1:2dd1bdf1834c53d048d3d9a7079b45afea5cecd7 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.

With r253161 in place, 2013-08-02T23:28:49Z Marius Strobl marius@FreeBSD.org 2013-08-02T23:28:49Z urn:sha1:c4b1deaf0d05e7ba715124b4c752edef80222115 this is is crucial at least for the latter. What happens is that attaching uart(4) to scc(4) causes the SAB 82532 to "receive" something and trigger a SER_INT_RXREADY interrupt, given that at least fast/filter interrupts are already enabled. Prior to r253161, uart_bus_ihand() was set up at this point and handled that condition, i. e. read the RX FIFO and issued a Receive Message Complete. Now, uart_bus_ihand() and uart_intr() are setup after attaching uart(4), leaving the SER_INT_RXREADY interrupt triggered during the latter to be handled by the iclear method. However, with that method not implement, this in turn causes SAB 82532 to not issue any further SER_INT_RXREADY interrupts until the RX FIFO is full again. Thus, 15 received bytes go to nowhere, given that "the other half" of the RX FIFO is used for status information. Hence, implementing sab82532_bfe_iclear() fixes things again. Potentially, the same problem exists for QUICC. - Remove unnecessary __RMAN_RESOURCE_VISIBLE. - Remove a superfluous header. - Use KOBJMETHOD_END. - Mark unused arguments as such. - Remove variables unused after initialization.

Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily.
