* Limit Options.inc generation to desired targetsEd Maste2016-05-051-2/+3
| | | | | | | | | | | | | | | | | As mentioned in the Makefile there's an "atrocious" hack to generate a different version of Options.inc.h, depending on the library being built. Remove the catch-all else case and limit it to specific libraries, so that we don't accidentally use the Options.inc.h from clangdriver if a future libary also uses Options.inc.h.

This ensures that namespacing is kept with FILES appropriately, and that this shouldn't need to be repeated if the namespace changes -- only the definition of PACKAGE needs to be changed - Allow PACKAGE to be overridden by callers instead of forcing it to always be `tests`. In the event we get to the point where things can be split up enough in the base system, it would make more sense to group the tests with the blocks they're a part of, e.g. byacc with byacc-tests, etc - Remove PACKAGE definitions where possible, i.e. where FILES wasn't used previously. - Remove unnecessary TESTSPACKAGE definitions; this has been elided into bsd.tests.mk - Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES; ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk. - Fix installation of files under data/ subdirectories in lib/libc/tests/hash and lib/libc/tests/net/getaddrinfo - Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup) Document the proposed changes in share/examples/tests/tests/... via examples so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of replacing FILES. share/mk/bsd.README didn't seem like the appropriate method of communicating that info.

* Improve performance and functionality of the bitstring(3) apiAlan Somers2016-05-041-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two new functions are provided, bit_ffs_at() and bit_ffc_at(), which allow for efficient searching of set or cleared bits starting from any bit offset within the bit string. Performance is improved by operating on longs instead of bytes and using ffsl() for searches within a long. ffsl() is a compiler builtin in both clang and gcc for most architectures, converting what was a brute force while loop search into a couple of instructions. All of the bitstring(3) API continues to be contained in the header file. Some of the functions are large enough that perhaps they should be uninlined and moved to a library, but that is beyond the scope of this commit. sys/sys/bitstring.h: Convert the majority of the existing bit string implementation from macros to inline functions. Properly protect the implementation from inadvertant macro expansion when included in a user's program by prefixing all private macros/functions and local variables with '_'. Add bit_ffs_at() and bit_ffc_at(). Implement bit_ffs() and bit_ffc() in terms of their "at" counterparts. Provide a kernel implementation of bit_alloc(), making the full API usable in the kernel. Improve code documenation. share/man/man3/bitstring.3: Add pre-exisiting API bit_ffc() to the synopsis. Document new APIs. Document the initialization state of the bit strings allocated/declared by bit_alloc() and bit_decl(). Correct documentation for bitstr_size(). The original code comments indicate the size is in bytes, not "elements of bitstr_t". The new implementation follows this lead. Only hastd assumed "elements" rather than bytes and it has been corrected. etc/mtree/BSD.tests.dist: tests/sys/Makefile: tests/sys/sys/Makefile: tests/sys/sys/bitstring.c: Add tests for all existing and new functionality. include/bitstring.h Include all headers needed by sys/bitstring.h lib/libbluetooth/bluetooth.h: usr.sbin/bluetooth/hccontrol/le.c: Include bitstring.h instead of sys/bitstring.h. sbin/hastd/activemap.c: Correct usage of bitstr_size(). sys/dev/xen/blkback/blkback.c Use new bit_alloc. sys/kern/subr_unit.c: Remove hard-coded assumption that sizeof(bitstr_t) is 1. Get rid of unrb.busy, which caches the number of bits set in unrb.map. When INVARIANTS are disabled, nothing needs to know that information. callapse_unr can be adapted to use bit_ffs and bit_ffc instead. Eliminating unrb.busy saves memory, simplifies the code, and provides a slight speedup when INVARIANTS are disabled. sys/net/flowtable.c: Use the new kernel implementation of bit-alloc, instead of hacking the old libc-dependent macro. sys/sys/param.h Update __FreeBSD_version to indicate availability of new API Submitted by: gibbs, asomers Reviewed by: gibbs, ngie MFC after: 4 weeks Sponsored by: Spectra Logic Corp Differential Revision: https://reviews.freebsd.org/D6004 Notes: svn path=/head/; revision=299090

* Remove useless calls to basename().Ed Schouten2016-05-011-2/+1
| | | | | | | | | | | | | | | | | There are a couple of places in the source three where we call basename() on constant strings. This is bad, because the prototype standardized by POSIX allows the implementation to use its argument as a storage buffer. This change eliminates some of these unportable calls to basename() in cases where it was only added for cosmetical reasons, namely to trim argv[0]. There's nothing wrong with setting argv[0] to the full path. Reviewed by: jilles Differential Revision: https://reviews.freebsd.org/D6093 Notes: svn path=/head/; revision=298876

| | | | | | | | | | | | | | | | 'devctl delete' can be used to delete a device that is no longer present. As an anti-foot-shooting measure, 'delete' will not delete a device unless it's parent bus says it is no longer present. This can be overridden by passing the force ('-f') flag. Note that this command should be used with care. If a device is deleted that is actually present it can't be resurrected unless the parent bus device's driver supports rescans.

* A new implementation of the loader block cacheAllan Jude2016-04-188-103/+189
| | | | | | | | | | | | | | | | | | | | The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy. Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks. Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device. The cache also implements limited read-ahead to increase performance. To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache.
