2020-03-20Use a separate copy of machdep.h in cp and ce driversEd Maste
Previously they included sys/dev/cx/machdep.h, but the cx driver was retired in r359178. These drivers haven't had real development for a decade or more so there's no real benefit in sharing this file; just copy it to the ce and cp subdirs. Notes: svn path=/head/; revision=359181

2020-03-02Add deprecation notices to ctau and cx driversEd Maste
These support outdated or obsolete ISA WAN (T1/E1) sync serial cards, and these drivers haven't really been touched (other than in tree-wide sweeps to keep them building) for 15+ years.

2018-06-02Use __builtin for various mem* and b* (e.g. bzero) routines.Mateusz Guzik
Some of the routines were using artificially limited builtin already, drop the explicit limit. The use of builtins allows quite often allows the compiler to elide the call or most zeroing to begin with. For instance, if the target object is 32 bytes in size and gets zeroed + has 16 bytes initialized, the compiler can just add code to zero out the rest. Note not all the primites have asm variants and some of the existing ones are not optimized. Maintaines are strongly encourage to take a look (regardless of this change).

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.

device drivers with calls to the centralised m_print() implementation. While the formatting and output details differ a little, the content is essentially the same, and it is unlikely anyone has used this debugging output in some time. This change reduces awareness of mbuf cluster allocation (and, especially, the M_EXT flag) outside of the mbuf allocator, which will make it easier to refine the external storage mechanism without disrupting drivers in the future.

framework for non-MPSAFE network protocols: - Remove debug_mpsafenet variable, sysctl, and tunable. - Remove NET_NEEDS_GIANT() and associate SYSINITSs used by it to force debug.mpsafenet=0 if non-MPSAFE protocols are compiled into the kernel. - Remove logic to automatically flag interrupt handlers as non-MPSAFE if debug.mpsafenet is set for an INTR_TYPE_NET handler. - Remove logic to automatically flag netisr handlers as non-MPSAFE if debug.mpsafenet is set. - Remove references in a few subsystems, including NFS and Cronyx drivers, which keyed off debug_mpsafenet to determine various aspects of their own locking behavior. - Convert NET_LOCK_GIANT(), NET_UNLOCK_GIANT(), and NET_ASSERT_GIANT into no-op's, as their entire behavior was determined by the value in debug_mpsafenet. - Alias NET_CALLOUT_MPSAFE to CALLOUT_MPSAFE. Many remaining references to NET_.*_GIANT() and NET_CALLOUT_MPSAFE are still present in subsystems, and will be removed in followup commits.

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.
