In Linux firewire subsystem, for IT context, some quadlets of isochronous packet payload can be indicated as a part of packet header to queue to the context. This commit uses the packet header to split CIP headers from CIP payload. As a result, regardless of CIP or non-CIP, context payload includes data blocks only. Signed-off-by:

This commit is a preparation to queue IT packet with header. To enable packet handler to fill the header, this commit uses kernel stack for data structure of packet parameter in several part of this file. Signed-off-by:

By taking into account the mapping from logical to DMA channels when enabling or disabling audio channels, ADAT channels 3 to 8 on the RME HDSPe AIO card are now correctly captured and played back in single speed mode. Since the mapping is an identity mapping for all cards except AIO and RayDAT, only those cards should be affected by this patch. It was tested on an AIO card. The patch needs testing on other cards, in particular RayDAT. Note: this patch does not solve ADAT capture and playback issues in double or triple speed mode. That seems to be another problem.

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(struct rate_priv) + src_format->channels * sizeof(struct rate_channel) with: struct_size(data, channels, src_format->channels) This code was detected with the help of Coccinelle.

Usage of 16 bytes IR context header allows to handle context payload by the same code for with-CIP and without-CIP packets. This commit unifies both handlers of with-CIP and without-CIP packets. Signed-off-by:

Takashi Sakamoto authored
In IR context, some quadlets of packet payload can be included into context header. This is good for packet with CIP header because the context payload buffer can includes data blocks only for with-CIP and without-CIP pakets. This commit uses 16 bytes IR context header for this purpose. Signed-off-by:

The value of pointer to payload buffer is computed in each packet handler, however the pointer can be decided before call of packet handler. This commit adds an argument for the pointer to the packet handler to reduce codes to compute for the pointer. Signed-off-by:

Takashi Sakamoto authored
In current packet handler, the length of payload is given as an argument of callback function, however this value is just required to process payload of transferred isoc packet, thus just for IR context. This commit replaces the argument for payload of packet with the argument of context header. As a result, the length of payload is computed in packet handler for IR context. Signed-off-by:

In IT context, header includes information of cycle to have processed queued packet. This commit uses the per-packet information to compute the cycle for packet to be queued, instead of callback argument. In current implementaion of ALSA IEC 61883-1/6 packet streaming engine, 48 packets are queued at first to skip recent cycle. When IT context calls handler, cycle information in header plus 48 cycle means the cycle to be going to queue packet. Signed-off-by:

Now four events of this module have the same arguments and probe timing. This commit adds a new event, 'amdtp_packet', and replace them. Filtering functionality of tracing framework is available to pick up events for inbound/outbound isochronous packets. Signed-off-by:

This modules handles two types of isochronous packet; one has CIP header in IEC 61883-1/6 and another doesn't. The module also have tracing events corresponding to the types of packet. To unify the events, one event should be probed with or without CIP header. This commit uses dynamic array for the events to be available for the types of packet. Signed-off-by:

ALSA: firewire-lib: add data_blocks/data_block_counter parameter to in_packet/out_packet tracing events Tracing events for packets without CIP header have a parameter of data_blocks/data_block_counter, but events for packets with CIP header don't. This is not good to unify these events. This commit adds the missing parameters to the events. In timing to probe 'in_packet' event, data_blocks and data_block_counter are not calculated yet. This commit also changes the timing. Signed-off-by:

FireStudio was launched by PreSonus 2009. This model consists of three ICs for its packet processing on IEEE 1394 bus: - Texus Instruments TSB41AB2 for physical layer of IEEE 1394 bus - WaveFront semiconductor, Dice II STD ASIC for link layer of IEEE 1394 bus and protocol layer - Xilinx Spartan XG3S500E FPGA for signal processing This model don't support TCAT extended application protocol. For such devices, ALSA dice driver needs to have hard-coded parameters for stream formats. This commit adds hard-coded table for this model. As a result, sampling transfer frequencies of 88.2/96.0 kHz are supported. I note that this patch can be backported to Linux kernel v4.18 and later. $ python2 crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 04042eda bus_info_length 4, crc_length 4, crc 11994 404 31333934 bus_name "1394" 408 e0ff8112 irmc 1, cmc 1, isc 1, bmc 0, pmc 0, cyc_clk_acc 255, max_rec 8 (512), max_rom 1, gen 1, spd 2 (S400) 40c 000a9204 company_id 000a92 | 410 023a8b7f device_id 04023a8b7f | EUI-64 000a9204023a8b7f root directory ----------------------------------------------------------------- 414 000661b6 directory_length 6, crc 25014 418 03000a92 vendor 41c 8100000a --> descriptor leaf at 444 420 17000008 model 424 8100000d --> descriptor leaf at 458 428 0c0087c0 node capabilities per IEEE 1394 42c d1000001 --> unit directory at 430 unit directory at 430 ----------------------------------------------------------------- 430 00041c75 directory_length 4, crc 7285 434 12000a92 specifier id 438 13000001 version 43c 17000008 model 440 8100000c --> descriptor leaf at 470 descriptor leaf at 444 ----------------------------------------------------------------- 444 00047c11 leaf_length 4, crc 31761 448 00000000 textual descriptor 44c 00000000 minimal ASCII 450 50726553 "PreS" 454 6f6e7573 "onus" descriptor leaf at 458 ----------------------------------------------------------------- 458 0005d7b3 leaf_length 5, crc 55219 45c 00000000 textual descriptor 460 00000000 minimal ASCII 464 46495245 "FIRE" 468 53545544 "STUD" 46c 494f0000 "IO" descriptor leaf at 470 ----------------------------------------------------------------- 470 0005d7b3 leaf_length 5, crc 55219 474 00000000 textual descriptor 478 00000000 minimal ASCII 47c 46495245 "FIRE" 480 53545544 "STUD" 484 494f0000 "IO" Signed-off-by:
