2016-02-27Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere().Justin Hibbits
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 Notes: svn path=/head/; revision=296137
2016-01-27Convert rman to use rman_res_t instead of u_longJustin Hibbits
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.

2015-01-06In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson
socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.

2009-06-26Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/Robert Watson
IF_ADDR_UNLOCK() across network device drivers when accessing the per-interface multicast address list, if_multiaddrs. This will allow us to change the locking strategy without affecting our driver programming interface or binary interface. For two wireless drivers, remove unnecessary locking, since they don't actually access the multicast address list. Approved by: re (kib) MFC after: 6 weeks Notes: svn path=/head/; revision=195049

2008-08-04Add locking to snc(4) so it is MPSAFE:John Baldwin
- Add a mutex to the softc to protect the softc and device hardware. - Use a private timer routine to drive the transmit watchdog timer instead of using if_watchdog/if_timer. - If if_alloc() fails during attach, fail the attach with an error rather than panic'ing. - Clear RUNNING and OACTIVE only in sncstop(). - Don't mess with IFF_UP. - Don't leak 'struct ifnet' on detach. - Setup interrupt handler after ether_ifattach(). - Call ether_ifdetach() rather than if_detach() in the pccard detach routine.

IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags.

2005-06-10Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis
struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

2004-05-08It turns out that the module dependency on pccard is in error. SinceWarner Losh
there's not dependencies on pccard symboles, such a dependency is not necessary. This means that drivers that have multiple attachments can not drag bogus devices into the kernel at load time. We can't (yet) do this with pci and isa. Drivers written for them actually do seem to have symbols that depend on these busses' implementation code. ndis not touched until other things can be tested.
