* Fix MFS builds when both MD_ROOT_SIZE and MFS_IMAGE are specifiedAdrian Chadd2016-02-021-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | MD_ROOT_SIZE and embed_mfs.sh were basically retired as part of https://reviews.freebsd.org/D2903 . However, when building a kernel with 'options MD_ROOT_SIZE' specified, this results in a non-working MFS, as within sys/dev/md/md.c we fall within the wrong # ifdef. This patch implements the following: * Allow kernels to be built without the MD_ROOT_SIZE option, which results in a kernel built as per D2903. * Allow kernels to be built with the MD_ROOT_SIZE option, which results in a kernel built similarly to the pre-D2903 way, with the following differences: * The MFS is now put in a separate section within the kernel (oldmfs, so it differs from the mfs section introduced by D2903). * embed_mfs.sh is changed, so it looks up the oldmfs section within the kernel, gets its size and offset, sees if the MFS will fit within the allocated oldmfs section and only if all is well does a dd of the MFS image into the kernel.

* - For kernel compiled only with KDTRACE_HOOKS and not any lock debuggingAttilio Rao2013-11-251-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | option, unbreak the lock tracing release semantic by embedding calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined version of the releasing functions for mutex, rwlock and sxlock. Failing to do so skips the lockstat_probe_func invokation for unlocking. - As part of the LOCKSTAT support is inlined in mutex operation, for kernel compiled without lock debugging options, potentially every consumer must be compiled including opt_kdtrace.h. Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES is linked there and it is only used as a compile-time stub [0]. [0] immediately shows some new bug as DTRACE-derived support for debug in sfxge is broken and it was never really tested. As it was not including correctly opt_kdtrace.h before it was never enabled so it was kept broken for a while. Fix this by using a protection stub, leaving sfxge driver authors the responsibility for fixing it appropriately [1].

* Further refine the handling of stop signals in the NFS client. TheJohn Baldwin2013-02-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | changes in r246417 were incomplete as they did not add explicit calls to sigdeferstop() around all the places that previously passed SBDRY to _sleep(). In addition, nfs_getcacheblk() could trigger a write RPC from getblk() resulting in sigdeferstop() recursing. Rather than manually deferring stop signals in specific places, change the VFS_*() and VOP_*() methods to defer stop signals for filesystems which request this behavior via a new VFCF_SBDRY flag. Note that this has to be a VFC flag rather than a MNTK flag so that it works properly with VFS_MOUNT() when the mount is not yet fully constructed. For now, only the NFS clients are set this new flag in VFS_SET(). A few other related changes: - Add an assertion to ensure that TDF_SBDRY doesn't leak to userland. - When a lookup request uses VOP_READLINK() to follow a symlink, mark the request as being on behalf of the thread performing the lookup (cnp_thread) rather than using a NULL thread pointer. This causes NFS to properly handle signals during this VOP on an interruptible mount.

Summary of changes includes: 1 Volume Per-Channel (vpc). Provides private / standalone volume control unique per-stream pcm channel without touching master volume / pcm. Applications can directly use SNDCTL_DSP_[GET|SET][PLAY|REC]VOL, or for backwards compatibility, SOUND_MIXER_PCM through the opened dsp device instead of /dev/mixer. Special "bypass" mode is enabled through /dev/mixer which will automatically detect if the adjustment is made through /dev/mixer and forward its request to this private volume controller. Changes to this volume object will not interfere with other channels. Requirements: - SNDCTL_DSP_[GET|SET][PLAY|REC]_VOL are newer ioctls (OSSv4) which require specific application modifications (preferred). - No modifications required for using bypass mode, so applications like mplayer or xmms should work out of the box. Kernel hints: - hint.pcm.%d.vpc (0 = disable vpc). Kernel sysctls: - hw.snd.vpc_mixer_bypass (default: 1). Enable or disable /dev/mixer bypass mode. - hw.snd.vpc_autoreset (default: 1). By default, closing/opening /dev/dsp will reset the volume back to 0 db gain/attenuation. Setting this to 0 will preserve its settings across device closing/opening. - hw.snd.vpc_reset (default: 0). Panic/reset button to reset all volume settings back to 0 db. - hw.snd.vpc_0db (default: 45). 0 db relative to linear mixer value. 2 High quality fixed-point Bandlimited SINC sampling rate converter, based on Julius O'Smith's Digital Audio Resampling - http://ccrma.stanford.edu/~jos/resample/. It includes a filter design script written in awk (the clumsiest joke I've ever written) - 100% 32bit fixed-point, 64bit accumulator. - Possibly among the fastest (if not fastest) of its kind. - Resampling quality is tunable, either runtime or during kernel compilation (FEEDER_RATE_PRESETS). - Quality can be further customized during kernel compilation by defining FEEDER_RATE_PRESETS in /etc/make.conf. Kernel sysctls: - hw.snd.feeder_rate_quality. 0 - Zero-order Hold (ZOH). Fastest, bad quality. 1 - Linear Interpolation (LINEAR). Slightly slower than ZOH, better quality but still does not eliminate aliasing. 2 - (and above) - Sinc Interpolation(SINC). Best quality. SINC quality always start from 2 and above. Rough quality comparisons: - http://people.freebsd.org/~ariff/z_comparison/ 3 Bit-perfect mode. Bypasses all feeder/dsp effects. Pure sound will be directly fed into the hardware. 4 Parametric (compile time) Software Equalizer (Bass/Treble mixer). Can be customized by defining FEEDER_EQ_PRESETS in /etc/make.conf. 5 Transparent/Adaptive Virtual Channel. Now you don't have to disable vchans in order to make digital format pass through. It also makes vchans more dynamic by choosing a better format/rate among all the concurrent streams, which means that dev.pcm.X.play.vchanformat/rate becomes sort of optional. 6 Exclusive Stream, with special open() mode O_EXCL. This will "mute" other concurrent vchan streams and only allow a single channel with O_EXCL set to keep producing sound. Other Changes: * most feeder_* stuffs are compilable in userland. Let's not speculate whether we should go all out for it (save that for FreeBSD 16.0-RELEASE). * kobj signature fixups, thanks to Andriy Gapon <avg@freebsd.org> * pull out channel mixing logic out of vchan.c and create its own feeder_mixer for world justice. * various refactoring here and there, for good or bad. * activation of few more OSSv4 ioctls() (see [1] above). * opt_snd.h for possible compile time configuration: (mostly for debugging purposes, don't try these at home) SND_DEBUG SND_DIAGNOSTIC SND_FEEDER_MULTIFORMAT SND_FEEDER_FULL_MULTIFORMAT SND_FEEDER_RATE_HP SND_PCM_64 SND_OLDSTEREO Manual page updates are on the way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a version that i posted earlier on the -current mailing list, and subsequent feedback received. The core of the change is just in sys/firmware.h and kern/subr_firmware.c, while other files are just adaptation of the clients to the ABI change (const-ification of some parameters and hiding of internal info, so this is fully compatible at the binary level). In detail: - reduce the amount of information exported to clients in struct firmware, and constify the pointer; - internally, document and simplify the implementation of the various functions, and make sure error conditions are dealt with properly. The diffs are large, but the code is really straightforward now (i hope). Note also that there is a subtle issue with the implementation of firmware_register(): currently, as in the previous version, we just store a reference to the 'imagename' argument, but we should rather copy it because there is no guarantee that this is a static string. I realised this while testing this code, but i prefer to fix it in a later commit -- there is no regression with respect to the past. Note, too, that the version in RELENG_6 has various bugs including missing locks around the module release calls, mishandling of modules loaded by /boot/loader, and so on, so an MFC is absolutely necessary there. I was just postponing it until this cleanup to avoid doing things twice. MFC after: 1 week Notes: svn path=/head/; revision=166756
