* ALSA: hda: codec: Reduce CONFIG_PM dependenciesTakashi Iwai2024-05-081-4/+0
| | | | | | | | | | | | CONFIG_PM is almost mandatory nowadays for real systems, but we have lots of CONFIG_PM dependent code in snd-hda-codec helper code. Let's reduce the dependencies of CONFIG_PM now. The only visible drawback would be a couple of superfluous trace entries for runtime PM, but we can live with that.

* ALSA: hda: Remove unused MAX_PIN_CONFIGS constantAmadeusz Sławiński2022-08-191-2/+0
| | | | | | | | | | | Since it was introduced around v2.6.30 it was never used. Also HDA specification does not mention any limitation on number of PIN configurations.

* ALSA: hda: Replace sprintf() with sysfs_emit()Takashi Iwai2022-08-021-12/+11
| | | | | | | | | For sysfs outputs, it's safer to use a new helper, sysfs_emit(), instead of the raw sprintf() & co. This patch replaces those usages straightforwardly with new helpers, sysfs_emit() and sysfs_emit_at().

* ALSA: hda: Fix regressions on clear and reconfig sysfsTakashi Iwai2020-12-101-1/+1
| | | | | | | | | | | | | | | | | | | It seems that the HD-audio clear and reconfig sysfs don't work any longer after the recent driver core change. There are multiple issues around that: the linked list corruption and the dead device handling. The former issue is fixed by another patch for the driver core itself, while the latter patch needs to be addressed in HD-audio side. This patch corresponds to the latter, it recovers those broken functions by replacing the device detach and attach actions with the standard core API functions, which are almost equivalent with unbind and bind actions.

* ALSA: hda: Use scnprintf() for printing texts for sysfs/procfsTakashi Iwai2020-02-181-2/+2
| | | | | | | | | | | | | | Some code in HD-audio driver calls snprintf() in a loop and still expects that the return value were actually written size, while snprintf() returns the expected would-be length instead. When the given buffer limit were small, this leads to a buffer overflow. Use scnprintf() for addressing those issues. It returns the actually written size unlike snprintf().

* ALSA: hda - Use a macro for snd_array iteration loopsTakashi Iwai2018-04-241-10/+10
| | | | | | | | | | | | Introduce a new helper macro, snd_array_for_each(), to iterate for each snd_array element. It slightly improves the readability than lengthy open codes at each place. Along with it, add const prefix to some obvious places. There should be no functional changes by this. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: hda - Fix broken reconfigTakashi Iwai2016-05-101-8/+0
| | | | | | | | | | | | | | | | | | | | | | The HD-audio reconfig function got broken in the recent kernels, typically resulting in a failure like: snd_hda_intel 0000:00:1b.0: control 3:0:0:Playback Channel Map:0 is already present This is because of the code restructuring to move the PCM and control instantiation into the codec drive probe, by the commit [bcd96557bd0a: ALSA: hda - Build PCMs and controls at codec driver probe]. Although the commit above removed the calls of snd_hda_codec_build_pcms() and *_build_controls() at the controller driver probe, the similar calls in the reconfig were still left forgotten. This caused the conflicting and duplicated PCMs and controls. The fix is trivial: just remove these superfluous calls from reconfig_codec().

* ALSA: hda - consolidate chip rename functionsTakashi Iwai2015-10-151-2/+1
| | | | | | | | A few multiple codec drivers do renaming the chip_name string but all these are open-coded and some of them have even no error check. Let's make common helpers to do it properly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Move a part of hda_codec stuff into hdac_deviceTakashi Iwai2015-03-231-29/+29
| | | | | | | | | | Now some codes and functionalities of hda_codec struct are moved to hdac_device struct. A few basic attributes like the codec address, vendor ID number, FG numbers, etc are moved to hdac_device, and they are accessed like codec->core.addr. The basic verb exec functions are moved, too.

* ALSA: hda - Move some codes up to hdac_bus structTakashi Iwai2015-03-231-1/+1
| | | | | | | | | | | | A few basic codes for communicating over HD-audio bus are moved to struct hdac_bus now. It has only command and get_response ops in addition to the unsolicited event handling. Note that the codec-side tracing support is disabled temporarily during this transition due to the code shuffling. It will be re-enabled later once when all pieces are settled down.

* ALSA: hda - Replace strnicmp with strncasecmpRasmus Villemoes2014-09-171-1/+1
| | | | | | | | | | | | | | | The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

* ALSA: hda - Replace with standard printkTakashi Iwai2014-02-251-3/+3
| | | | | | | | | | | | Use dev_err() and co for messages from HD-audio controller and codec drivers. The codec drivers are mostly bound with codec objects, so some helper macros, codec_err(), codec_info(), etc, are provided. They merely wrap the corresponding dev_xxx(). There are a few places still calling snd_printk() and its variants as they are called without the codec or device context. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Enable sysfs attributes without CONFIG_SND_HDA_RECONFIGTakashi Iwai2014-02-251-77/+88
| | | | | | | | | Some sysfs attributes like init_pin_configs or vendor_name are really basic and should be available no matter whether the codec driver is re-configurable or not. Put them out of #ifdef CONFIG_SND_HDA_RECONFIG and allow the read-only accesses. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Add sysfs to codec object, tooTakashi Iwai2014-02-251-0/+769
We have currently sysfs attributes for each hwdep, but basically these should belong to the codec itself, per se. Let's add them to the codec object while keeping them for hwdep as is for compatibility. While we are at it, split the sysfs-related stuff into a separate source file, hda_sysfs.c, and keep only the stuff necessary for hwdep in hda_hwdep.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
