Mark of the Unicorn released 896 mk3 FireWire in 2008 as part of the third generation of its FireWire series. In 2011, 896 mk3 hybrid was released to support USB protocol. It supports sampling transfer frequency up to 192.0 kHz. The packet format differs depending on both of current sampling transfer frequency and the type of signal in optical interfaces. The model supports transmission of PCM frames as well as MIDI messages. The 896 mk3 FireWire consists of below ICs: * Texas Instruments TSB41AB2 * Xilinx Spartan-3A FPGA, XC3S500E * Texas Instruments TMS320C6722 * Microchip (Atmel) AT91SAM SAM7S256 It supports sampling transfer frequency up to 192.0 kHz. The packet format differs depending on both of current sampling transfer frequency and the type of signal in two pairs of optical interfaces. The model supports transmission of PCM frames, while has no port for MIDi messages. The model supports command mechanism to configure internal DSP. Hardware meter information is available in the first 2 chunks of each data block of tx packet. This commit adds support for it. The 896 mk3 FireWire is just tested, but the 896 mk3 Hybrid is not yet. $ config-rom-pretty-printer < motu-896mk3fw.img ROM header and bus information block ----------------------------------------------------------------- 1024 04100ce1 bus_info_length 4, crc_length 16, crc 3297 1028 31333934 bus_name "1394" 1032 20ff7000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 1036 0001f200 company_id 0001f2 | 1040 00093add device_id 0000604893 | EUI-64 0547556791237341 root directory ----------------------------------------------------------------- 1044 0004ef04 directory_length 4, crc 61188 1048 030001f2 vendor 1052 0c0083c0 node capabilities: per IEEE 1394 1056 d1000002 --> unit directory at 1064 1060 8d000005 --> eui-64 leaf at 1080 unit directory at 1064 ----------------------------------------------------------------- 1064 0003998d directory_length 3, crc 39309 1068 120001f2 specifier id 1072 13000017 version 1076 17101800 model eui-64 leaf at 1080 ----------------------------------------------------------------- 1080 0002cc82 leaf_length 2, crc 52354 1084 0001f200 company_id 0001f2 | 1088 00093add device_id 0000604893 | EUI-64 0547556791237341 $ config-rom-pretty-printer < motu-896mk3hybrid.img ROM header and bus information block ----------------------------------------------------------------- 1024 04103cbe bus_info_length 4, crc_length 16, crc 15550 1028 31333934 bus_name "1394" 1032 20ff7000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 1036 0001f200 company_id 0001f2 | 1040 000ae601 device_id 0000714241 | EUI-64 0547556791346689 root directory ----------------------------------------------------------------- 1044 0004ef04 directory_length 4, crc 61188 1048 030001f2 vendor 1052 0c0083c0 node capabilities: per IEEE 1394 1056 d1000002 --> unit directory at 1064 1060 8d000005 --> eui-64 leaf at 1080 unit directory at 1064 ----------------------------------------------------------------- 1064 000394ac directory_length 3, crc 38060 1068 120001f2 specifier id 1072 13000037 version 1076 17102800 model eui-64 leaf at 1080 ----------------------------------------------------------------- 1080 0002cf69 leaf_length 2, crc 53097 1084 0001f200 company_id 0001f2 | 1088 000ae601 device_id 0000714241 | EUI-64 0547556791346689 Signed-off-by:Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20240129022711.254383-1-o-takashi@sakamocchi.jpSigned-off-by:

Slightly re-work the code around cs35l41_generic_fixup() and the component binding search so that it can be re-used for other amps that use the component binding mechanism. The match string is stored in struct scodec_dev_name instead of hardcoding it in the match function. The tas2781 does not use the amp index as part of the driver name match. But its match format string does not include a field for the index, so snprintf() would safely ignore the p->index argument. Because of this there is no need for a special match function for this case, the CS35L41 code can be re-used. Signed-off-by:

bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate. Signed-off-by: -
