| 2300 | + The option provides a refined and flexible control for applying quirk | |
| 2301 | + flags. It allows to specify the quirk flags for each device, and can | |
| 2302 | + be modified dynamically via sysfs. | |
| 2303 | + The old usage accepts an array of integers, each of which applies quirk | |
| 2304 | + flags on the device in the order of probing. | |
| 2305 | + E.g., ``quirk_flags=0x01,0x02`` applies get_sample_rate to the first | |
| 2306 | + device, and share_media_device to the second device. | |
| 2307 | + The new usage accepts a string in the format of | |
| 2308 | + ``VID1:PID1:FLAGS1;VID2:PID2:FLAGS2;...``, where ``VIDx`` and ``PIDx`` | |
| 2309 | + specify the device, and ``FLAGSx`` specify the flags to be applied. | |
| 2310 | + ``VIDx`` and ``PIDx`` are 4-digit hexadecimal numbers, and can be | |
| 2311 | + specified as ``*`` to match any value. ``FLAGSx`` can be a set of | |
| 2312 | + flags given by name, separated by ``|``, or a hexadecimal number | |
| 2313 | + representing the bit flags. The available flag names are listed below. | |
| 2314 | + An exclamation mark can be prefixed to a flag name to negate the flag. | |
| 2315 | + For example, ``1234:abcd:mixer_playback_min_mute|!ignore_ctl_error;*:*:0x01;`` | |
| 2316 | + applies the ``mixer_playback_min_mute`` flag and clears the | |
| 2317 | + ``ignore_ctl_error`` flag for the device 1234:abcd, and applies the | |
| 2318 | + ``skip_sample_rate`` flag for all devices. | |
| 2319 | + | |
| 2320 | + * bit 0: ``get_sample_rate`` | |
| 2321 | + Skip reading sample rate for devices | |
| 2322 | + * bit 1: ``share_media_device`` | |
| 2323 | + Create Media Controller API entries | |
| 2324 | + * bit 2: ``align_transfer`` | |
| 2325 | + Allow alignment on audio sub-slot at transfer | |
| 2326 | + * bit 3: ``tx_length`` | |
| 2327 | + Add length specifier to transfers | |
| 2328 | + * bit 4: ``playback_first`` | |
| 2329 | + Start playback stream at first in implement feedback mode | |
| 2330 | + * bit 5: ``skip_clock_selector`` | |
| 2331 | + Skip clock selector setup | |
| 2332 | + * bit 6: ``ignore_clock_source`` | |
| 2333 | + Ignore errors from clock source search | |
| 2334 | + * bit 7: ``itf_usb_dsd_dac`` | |
| 2335 | + Indicates ITF-USB DSD-based DACs | |
| 2336 | + * bit 8: ``ctl_msg_delay`` | |
| 2337 | + Add a delay of 20ms at each control message handling | |
| 2338 | + * bit 9: ``ctl_msg_delay_1m`` | |
| 2339 | + Add a delay of 1-2ms at each control message handling | |
