* ALSA: firewire: Clean up a locking issue in copy_resp_to_buf()Dan Carpenter2020-11-131-2/+2
| | | | | | | | | | | | | | | | | | The spin_lock/unlock_irq() functions cannot be nested. The problem is that presumably we would want the IRQs to be re-enabled on the second call the spin_unlock_irq() but instead it will be enabled at the first call so IRQs will be enabled earlier than expected. In this situation the copy_resp_to_buf() function is only called from one function and it is called with IRQs disabled. We can just use the regular spin_lock/unlock() functions.

| * ALSA: firewire: Replace tasklet with workTakashi Iwai2020-09-112-13/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In FireWire driver, a tasklet is still used for offloading the AMDTP PCM stream handling. It can be achieved gracefully with a work queued, too. This patch replaces the tasklet usage in firewire-lib driver with a simple work. The conversion is fairly straightforward but for the in_interrupt() checks that are replaced with the check using the current_work(). Note that in_interrupt() in amdtp_packet tracepoint is still kept as is. This is the place that is probed by both softirq of 1394 OHCI and a user task of a PCM application, and the work handling is already filtered in amdtp_domain_stream_pcm_pointer().

|/ | | | | | | | | | | | | | | | | | | | Tascam FE-8 is known to support communication by asynchronous transaction only. The support can be implemented in userspace application and snd-firewire-ctl-services project has the support. However, ALSA firewire-tascam driver is bound to the model. This commit changes device entries so that the model is excluded. In a commit 53b3ffee7885 ("ALSA: firewire-tascam: change device probing processing"), I addressed to the concern that version field in configuration differs depending on installed firmware. However, as long as I checked, the version number is fixed. It's safe to return version number back to modalias.

* ALSA: firewire-motu: wait for notification when changing clock configuration ↵Takashi Sakamoto2020-06-151-3/+13
| | | | | | | | | | | | | | | | | for protocol v3 It costs expensive to change clock configuration for models of protocol version 3. In current implementation, speculative strategy is used to finish the operation; just waiting for 4 seconds. As long as I investigate, when accepting and changing clock status actually, the device sends notification with mask. This commit uses wise way to wait for the notification after changing sampling clock rate during 4 seconds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In MOTU protocol, data block consists of SPH and 24-bit chunks aligned to quadlet. The number of chunks per data block is specific to model. For models with optical interface, the number differs depending on I/O settings for the interface (ADAT, TOSLINK). Currently the number is calculated from flags in model-specific data. However this is weak in the case that the model has quirks. Actually, for quirks of some models, flags are used against their original meanings. This commit adds model-specific table of chunk count. For future integration, this table is based on the calculation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fireface UFX was shipped by RME GmbH in 2010, and now discontinued. Although this model has some enhanced feature which Fireface 802 doesn't have (e.g. on-board USB mass storage device class, configuration interface with color display), the functionality relevant to packet communication on IEEE 1394 bus seems to be the same as Fireface 802 (e.g. available number of channels for PCM frame in each sampling transfer frequency). With the assumption, this commit adds support for Fireface UFX. In ALSA fireface driver, these two models are handled as the same one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fireface 802 was shipped by RME GmbH in 2014. This model supports later protocol for management of isochronous communication and synchronization of sampling transmission frequency. This model consists of below ICs: * TI TSB41AB2 * Xilinx Spartan-6 FPGA XC6SLX16 * TI TMS320 C6747 * SMSC USB3250 Especially, this model just supports IEEE 1394a, against its name which evokes Fireface 800. This commit adds support for Fireface 802 (tested). Userspace applications can transfer PCM frames and MIDI messages via ALSA PCM/Rawmidi interface. I note that 4 channels for ADAt1 and ADAT2 are disabled at higher sampling transfer frequency since isochronous resources reservation fails due to bandwidth limitation of IEEE 1394a. The value read from LATTER_SYNC_STATUS register is slightly different from the one of Fireface UCX. The higher 4 bits and lower 4 bits are swapped within the same byte. Without any assist of userspace application, transmitted MIDI messages from the device are not going to be processed. For detail, please refer to my comment in code of latter protocol. $ python crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 0404ffff bus_info_length 4, crc_length 4, crc 65535 (should be 26805) 404 31333934 bus_name "1394" 408 20008000 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 0, max_rec 8 (512) 40c 000a3504 company_id 000a35 | 410 38077423 device_id 0438077423 | EUI-64 000a350438077423 root directory ----------------------------------------------------------------- 414 0005ffff directory_length 5, crc 65535 (should be 9514) 418 0c0083c0 node capabilities per IEEE 1394 41c 03000a35 vendor 420 8100000b --> descriptor leaf at 44c 424 8d000007 --> eui-64 leaf at 440 428 d1000001 --> unit directory at 42c unit directory at 42c ----------------------------------------------------------------- 42c 0004ffff directory_length 4, crc 65535 (should be 45134) 430 12000a35 specifier id 434 13000005 version 438 17101800 model 43c 81000008 --> descriptor leaf at 45c eui-64 leaf at 440 ----------------------------------------------------------------- 440 0002ffff leaf_length 2, crc 65535 (should be 60131) 444 000a3504 company_id 000a35 | 448 38077423 device_id 0438077423 | EUI-64 000a350438077423 descriptor leaf at 44c ----------------------------------------------------------------- 44c 0003ffff leaf_length 3, crc 65535 (should be 469) 450 00000000 textual descriptor 454 00000000 minimal ASCII 458 524d4521 "RME!" descriptor leaf at 45c ----------------------------------------------------------------- 45c 0005ffff leaf_length 5, crc 65535 (should be 10561) 460 00000000 textual descriptor 464 00000000 minimal ASCII 468 46697265 "Fire" 46c 66616365 "face" 470 20383032 " 802" Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20200510074301.116224-6-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the latter models of RME Fireface series, device start to transfer packets several dozens of milliseconds. On the other hand, ALSA fireface driver starts IR context 2 milliseconds after the start. This results in loss to handle incoming packets on the context. This commit changes to start IR context immediately instead of postponement. For Fireface 800, this affects nothing because the device transfer packets 100 milliseconds or so after the start and this is within wait timeout.

* | ALSA: fireworks: Replace zero-length array with flexible-arrayGustavo A. R. Silva2020-05-081-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.
