We can simplify the code gracefully with new guard() macro and co for automatic cleanup of locks. There are a few remaining explicit mutex and spinlock calls, and those are the places where the temporary unlock/relocking happens -- which guard() doens't cover well yet.

We can simplify the code gracefully with new guard() macro and co for automatic cleanup of locks. The lops calls under multiple rwsems are factored out as a simple macro, so that it can be called easily from snd_ctl_dev_register() and snd_ctl_dev_disconnect(). There are a few remaining explicit rwsem and spinlock calls, and those are the places where the lock downgrade happens or where the temporary unlock/relocking happens -- which guard() doens't cover well yet. Only the code refactoring, and no functional changes. Signed-off-by:

We can simplify the code gracefully with new guard() macro and co for automatic cleanup of locks. There are still a few remaining explicit mutex_lock/unlock calls, and those are for the places where we do temporary unlock/relock, which doesn't fit well with the guard(), so far. Only the code refactoring, and no functional changes. Signed-off-by:

We can simplify the code gracefully with new guard() macro and co for automatic cleanup of locks. For making changes easier, some functions widen the application of register_mutex, but those shouldn't influence on any actual performance. Also, one code block was factored out as a function so that guard() can be applied cleanly without much indentation. There are still a few remaining explicit spin_lock/unlock calls, and those are for the places where we do temporary unlock/relock, which doesn't fit well with the guard(), so far.

There were a few sparse warnings about the cast of strong-typed snd_pcm_format_t. Fix them with cast with __force. For spreading the ugly mess, put them in the definitions WRONG_FORMAT_1 and WRONG_FORMAT_2 and use them in the callers. Fixes: 3e39acf5 ("ALSA: core: Add sound core KUnit test") Reported-by:

There are common patterns where a temporary buffer is allocated and freed at the exit, and those can be simplified with the recent cleanup mechanism via __free(kfree). A caveat is that some allocations are memdup_user() and they return an error pointer instead of NULL. Those need special cares and the value has to be cleared with no_free_ptr() at the allocation error path. Other than that, the conversions are straightforward.

The HP mt440 Thin Client uses an ALC236 codec and needs the ALC236_FIXUP_HP_MUTE_LED_MICMUTE_VREF quirk to make the mute and micmute LEDs work. There are two variants of the USB-C PD chip on this device. Each uses a different BIOS and board ID, hence the two entries. Signed-off-by:

When BDL table entry overflow happens, the driver spews an error message explicitly. But basically this condition can be triggered easily by an application and it may flood of error logs unnecessarily. Downgrade the error message with dev_dbg() as a debug message instead.

So far the setup of BDL table is performed at the prepare stage, where all PCM parameters have been already set up. When something wrong happens at it, we return -EINVAL; it's supposed to be a rare case since the involved memory allocation is a small chunk of kmalloc for the table. However, when we receive too many small non-contiguous pages in highly fragmented memories, it may overflow the max table size, resulting in the same -EINVAL error from the prepare, too. A bad scenario is that user-space cannot know what went wrong (as it's an error from the prepare stage) and -EINVAL, hence it may retry with the same parameters, failing again repeatedly. In this patch, we try to set up the BDL table at hw_params right after the buffer allocation, and return -ENOMEM if it overflows. This allows user-space knowing that it should reduce the buffer size request accordingly and may retry with more fitting parameters.

On my EliteBook 840 G8 Notebook PC (ProdId 5S7R6EC#ABD; built 2022 for german market) the Mute LED is always on. The mute button itself works as expected. alsa-info.sh shows a different subsystem-id 0x8ab9 for Realtek ALC285 Codec, thus the existing quirks for HP 840 G8 don't work. Therefore, add a new quirk for this type of EliteBook. Signed-off-by:

The Dell Inspiron 16 Plus 7630, similar to its predecessors (7620 models), experiences an issue with unconnected top speakers. Since the controller remains unchanged, this commit addresses the problem by correctly connecting the speakers on NID 0X17 to the DAC on NIC 0x03. Signed-off-by:

The local helper function to compare the given pair of cycle count evaluates them. If the left value is less than the right value, the function returns negative value. If the safe cycle is less than the current cycle, it is the case of cycle lost. However, it is not currently handled properly. This commit fixes the bug.

Miglia Technology ships Harmony Audio 2004. It uses Oxford Semiconductor OXFW970 for communication function in IEEE 1394 bus. This commit adds support for the model. In my opinion, the firmware of ASIC is really the initial stage, since it has the following quirks. * It skips several isochronous cycles to transmit isochronous packets when receiving any asynchronous transaction. * The value of dbc field in the transmitted packet is the number of accumulated quadlets in CIP payload, instead of the accumulated data blocks. Furthermore, the value includes the quadlets of CIP payload in the packet. * It neither supports AV/C Stream Format Information command nor AV/C Extended Stream Format Information command. * The vendor and model information in root directory of configuration ROM includes some mistakes. Additionally, when operating at 96.0 kHz, it often skips much isochronous cycles to transmit the isochronous packets. The issue is detected as cycle discontinuity and ALSA PCM application receives -EIO at any operation for PCM substream. I have never found any workaround yet. $ config-rom-pretty-printer < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 1024 04249e04 bus_info_length 4, crc_length 36, crc 40452 1028 31333934 bus_name "1394" 1032 20ff5003 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 5 (64) 1036 0030e002 company_id 0030e0 | 1040 00454647 device_id 8594474567 | EUI-64 13757098081207879 root directory ----------------------------------------------------------------- 1044 00062d69 directory_length 6, crc 11625 1048 030030e0 vendor 1052 8100000a --> descriptor leaf at 1092 1056 1700f970 model 1060 81000011 --> descriptor leaf at 1128 1064 0c0083c0 node capabilities: per IEEE 1394 1068 d1000001 --> unit directory at 1072 unit directory at 1072 ----------------------------------------------------------------- 1072 00046ff9 directory_length 4, crc 28665 (should be 43676) 1076 1200a02d specifier id 1080 13010001 version 1084 1700f970 model 1088 8100000f --> descriptor leaf at 1148 descriptor leaf at 1092 ----------------------------------------------------------------- 1092 00085f8a leaf_length 8, crc 24458 1096 00000000 textual descriptor 1100 00000000 minimal ASCII 1104 4d69676c "Migl" 1108 69612054 "ia T" 1112 6563686e "echn" 1116 6f6c6f67 "olog" 1120 79204c74 "y Lt" 1124 642e0000 "d." descriptor leaf at 1128 ----------------------------------------------------------------- 1128 00040514 leaf_length 4, crc 1300 1132 00000000 textual descriptor 1136 00000000 minimal ASCII 1140 4f584657 "OXFW" 1144 20393730 " 970" descriptor leaf at 1148 ----------------------------------------------------------------- 1148 0005a1dc leaf_length 5, crc 41436 1152 00000000 textual descriptor 1156 00000000 minimal ASCII 1160 4861726d "Harm" 1164 6f6e7941 "onyA" 1168 7564696f "udio" Signed-off-by: -
