[alsa-devel] [PATCH 0/4] davinci-mcasp: fix tdm_slots and CBM/CFS
by Ben Gardiner 26 Apr '11

26 Apr '11

This patch series is comprised of three bugfixes and one cleanup that were performed during prototyping of McASP operation in codec clock- master frame-slave mode. First we noticed that the check of the number of tdm slots requested by platform data was always returning true -- unrelated to CMB/CFS mode. Then a cleanup: the PDIR values set are currently based on magic numbers and there are available bitfield definitions. Not strictly needed but it makes the changes introduced in the last patch simpler to read. It was found that the hardware parameters assigned when codec clock-master frame-slave is requested were incorrect. This change is required for correct CBM/CFS operation. Finally, the direction of the pins is corrected to reflect the implications of codec clock-master frame-slave -- i.e. mcasp clock- input frame-output. This change is also required for correct operation. The combination was tested with a logic analyzer and the hrtimer pwm device from Bill Gatliff's PWM framework [1] on a da850evm with hardware modifications to access the McASP lines.

[alsa-devel] [PATCH] firewire: octlet AT payloads can be stack-allocated
by Stefan Richter 26 Apr '11

26 Apr '11

...provided that the allocation persists until the packet was sent out to the bus. But we do not need slab allocations anymore in order to satisfy streaming DMA mapping constraints, thanks to commit da28947e7e36 "firewire: ohci: avoid separate DMA mapping for small AT payloads". (Besides, the slab-allocated buffers that firewire-core, firewire-sbp2, and firedtv used to provide for 8-byte write and lock requests were still not fully portable since they crossed cacheline boundaries or shared a cacheline with unrelated CPU-accessed data. snd-firewire-lib got this aspect right by using an extra kmalloc/ kfree just for the 8-byte transaction buffer.) This change replaces kmalloc'ed lock transaction scratch buffers in firewire-core, firedtv, and snd-firewire-lib by local stack allocations. The lifetime requirement of these allocations is fulfilled because the call sites use the blocking fw_run_transaction API. Perhaps the most notable result of the change is simpler locking because there is no need to serialize usages of preallocated per-device buffers anymore. Also, allocations and deallocations are simpler. firewire-sbp2's struct sbp2_orb.pointer buffer for 8-byte block write requests on the other hand needs to remain slab-allocated in order to keep the allocation around until end of AT DMA. Signed-off-by: Stefan Richter <stefanr(a)s5r6.in-berlin.de> --- Tested with firedtv, snd-firewire-speakers, sind-isight, and Coriander on a kernel with CONFIG_DMA_API_DEBUG=y. The patch could be split into three parts --- one for firedtv alone, one for the firewire-core an snd-firewire-lib fw_iso_resource_manage related changes, and one for the other changes in firewire-core. But since the second one necessarily affects both drivers/firewire/ and sound/firewire/ and because they all depend functionally on a change in linux1394-2.6.git master, there is no much benefit in breaking this up. drivers/firewire/core-card.c | 16 ++++++++-------- drivers/firewire/core-cdev.c | 4 +--- drivers/firewire/core-iso.c | 21 +++++++++++---------- drivers/firewire/core-transaction.c | 7 ++++--- drivers/media/dvb/firewire/firedtv-avc.c | 15 +-------------- include/linux/firewire.h | 3 +-- sound/firewire/cmp.c | 3 +-- sound/firewire/iso-resources.c | 12 +++--------- sound/firewire/iso-resources.h | 1 - 9 files changed, 30 insertions(+), 52 deletions(-) Index: b/drivers/firewire/core-card.c =================================================================== --- a/drivers/firewire/core-card.c +++ b/drivers/firewire/core-card.c @@ -258,8 +258,7 @@ static void allocate_broadcast_channel(s if (!card->broadcast_channel_allocated) { fw_iso_resource_manage(card, generation, 1ULL << 31, - &channel, &bandwidth, true, - card->bm_transaction_data); + &channel, &bandwidth, true); if (channel != 31) { fw_notify("failed to allocate broadcast channel\n"); return; @@ -294,6 +293,7 @@ static void bm_work(struct work_struct * bool root_device_is_cmc; bool irm_is_1394_1995_only; bool keep_this_irm; + __be32 transaction_data[2]; spin_lock_irq(&card->lock); @@ -355,21 +355,21 @@ static void bm_work(struct work_struct * goto pick_me; } - card->bm_transaction_data[0] = cpu_to_be32(0x3f); - card->bm_transaction_data[1] = cpu_to_be32(local_id); + transaction_data[0] = cpu_to_be32(0x3f); + transaction_data[1] = cpu_to_be32(local_id); spin_unlock_irq(&card->lock); rcode = fw_run_transaction(card, TCODE_LOCK_COMPARE_SWAP, irm_id, generation, SCODE_100, CSR_REGISTER_BASE + CSR_BUS_MANAGER_ID, - card->bm_transaction_data, 8); + transaction_data, 8); if (rcode == RCODE_GENERATION) /* Another bus reset, BM work has been rescheduled. */ goto out; - bm_id = be32_to_cpu(card->bm_transaction_data[0]); + bm_id = be32_to_cpu(transaction_data[0]); spin_lock_irq(&card->lock); if (rcode == RCODE_COMPLETE && generation == card->generation) @@ -490,11 +490,11 @@ static void bm_work(struct work_struct * /* * Make sure that the cycle master sends cycle start packets. */ - card->bm_transaction_data[0] = cpu_to_be32(CSR_STATE_BIT_CMSTR); + transaction_data[0] = cpu_to_be32(CSR_STATE_BIT_CMSTR); rcode = fw_run_transaction(card, TCODE_WRITE_QUADLET_REQUEST, root_id, generation, SCODE_100, CSR_REGISTER_BASE + CSR_STATE_SET, - card->bm_transaction_data, 4); + transaction_data, 4); if (rcode == RCODE_GENERATION) goto out; } Index: b/drivers/firewire/core-cdev.c =================================================================== --- a/drivers/firewire/core-cdev.c +++ b/drivers/firewire/core-cdev.c @@ -141,7 +141,6 @@ struct iso_resource { int generation; u64 channels; s32 bandwidth; - __be32 transaction_data[2]; struct iso_resource_event *e_alloc, *e_dealloc; }; @@ -1229,8 +1228,7 @@ static void iso_resource_work(struct wor r->channels, &channel, &bandwidth, todo == ISO_RES_ALLOC || todo == ISO_RES_REALLOC || - todo == ISO_RES_ALLOC_ONCE, - r->transaction_data); + todo == ISO_RES_ALLOC_ONCE); /* * Is this generation outdated already?

Refer to commit 1564b2878f5cf160f60af99d4dbca1dd7809ee8a ALSA: HDA VIA: Add smart5.1 function. Smart 5.1 is for 3-jacks model, to reuse input pins as outputs. While off, they act as "line out" / "line in" / "mic in". While on, they acts as "line out" / "back left/right" / "center/lfe". There are several bug report related to Smart 5.1 switch and motherboard with 6 audio jacks at rear panel Should the driver deactivate or remove "Smart 5.1" switch for the motherboard which does not need reuse input pins as outputs (e.g. motherboard with 5 or 6 audio jacks at rear panel) ?
