branches: 1.18.16; Merge thorpej-cfargs branch:
Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments.
Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.)
Remove unnecessary or redundant interface attributes where they're not needed.
There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation.
To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

port-arm/49057: Raspberry Pi Audio volume control does not work
AUDS server messages expect volume to be expressed in units of 1/256 dB, where we previously (incorrectly) treated it as as percentage. Map the NetBSD audio level (0-255) to 20 steps (levels from FreeBSD bcm2835_audio.c) and provide independent volume knobs for outputs.auto, outputs.hdmi, and outputs.headphones.

Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation.
To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

port-arm/49057: Raspberry Pi Audio volume control does not work
AUDS server messages expect volume to be expressed in units of 1/256 dB, where we previously (incorrectly) treated it as as percentage. Map the NetBSD audio level (0-255) to 20 steps (levels from FreeBSD bcm2835_audio.c) and provide independent volume knobs for outputs.auto, outputs.hdmi, and outputs.headphones.

Merge isaki-audio2 branch, the overhaul of audio subsystem. - Interrupt-oriented system rather than thread-oriented. - Improve stability, quality and performance. - Split playback and record cleanly. Improve halfduplex support. - Many bugs are fixed including deadlocks, resource leaks, abuses, etc. - Simplify audio filter mechanism. The encoding/channels/frequency conversions are completely handled in the upper layer. So the hard- ware driver only converts its hardware encoding (if necessary). - audio_hw_if changes: - Obsoletes query_encoding and add query_format instead. - Obsoletes set_params and add set_format instead. - Remove drain, setfd, mappage. - The call sequences are changed. - ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted. - ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced. - cleanup config attributes: au*conv and mulaw. - All hardware drivers should follow it (I've done as much as possible).
Some file paths are changed: - dev/audio.c -> dev/audio/audio.c (rewritten) - dev/audiovar.h -> dev/audio/audiovar.h - dev/audio_dai.h -> dev/audio/audio_dai.h - dev/audio_if.h -> dev/audio/audio_if.h - dev/audiobell.c -> dev/audio/audiobell.c - dev/audiobellvar.h -> dev/audio/audiobellvar.h - dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation.
To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

port-arm/49057: Raspberry Pi Audio volume control does not work
AUDS server messages expect volume to be expressed in units of 1/256 dB, where we previously (incorrectly) treated it as as percentage. Map the NetBSD audio level (0-255) to 20 steps (levels from FreeBSD bcm2835_audio.c) and provide independent volume knobs for outputs.auto, outputs.hdmi, and outputs.headphones.

port-arm/49057: Raspberry Pi Audio volume control does not work
AUDS server messages expect volume to be expressed in units of 1/256 dB, where we previously (incorrectly) treated it as as percentage. Map the NetBSD audio level (0-255) to 20 steps (levels from FreeBSD bcm2835_audio.c) and provide independent volume knobs for outputs.auto, outputs.hdmi, and outputs.headphones.

port-arm/49057: Raspberry Pi Audio volume control does not work
- Use software volume control for outputs.master/inputs.dac - Previous volume control (for analog output only) is available on new outputs.headphones mixer control. - Add an outputs.select enum to choose between "auto", "headphones", and "hdmi" outputs.

branches: 1.7.2; Some improvements that make playback mostly reliable for me - the final piece of the jigaw is probably in vchiq:
- prefill vchiq with a number (currently 2) blocks of audio before starting
- use a kthread as workqueue isn't suited to our usage.
- don't drain on stopping as for some reason it leaves data behind.

capture peer version; if less than 2, bail out as bulk mode is not supported. report the peer version with "audioctl version"

branches: 1.3.2; 1.3.4; Improve locking and kcondvar usage.
The "interrupt" lock doesn't need to be a spin mutex as the vchi completions we're synchronising with are done in thread context.
Don't share the interrupt lock for the msg_sync done synchronisation.
