2012-10-20ALSA: hdspm - Fix reported autosync_sample_rateAdrian Knoth
Missing breaks lead to a fall-through, thus causing the wrong autosync_sample_rate to be reported. Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-10-20ALSA: hdspm - Fix sync check reporting on all RME HDSPM cardsAdrian Knoth
Due to missing breaks and the resulting fall-through, card subtype selection was effectively missing, thus causing the wrong sync check functions to be called. Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-10-20ALSA: hdspm - Report external rate in slave mode on PCI MADIAdrian Knoth
As a follow-up to a97bda7d29d02a2e9c6609d0947b15e55f5200e5, report the external sample rate as system_sample_rate when in slave mode. For PCIe MADI cards, the DDS value automatically contains the external sample rate, but the PCI version needs this manual workaround.

2012-10-20ALSA: hdspm - Allow DDS/Varispeed to be set from userspaceAdrian Knoth
The DDS value is the actual physical sample rate. We set it indirectly when selecting 44100, 48000 and so on via snd_hdspm_hw_params or hdspm_set_clock_source. This commit now allows the DDS value to be altered at runtime, thus speeding up or slowing down the physical sample rate. This is required for MADI's varispeed that allows for ±12.5% speed adjustment from the "selected" rate (32kHz, 44100kHz, 48kHz and so on).

Convert a nonnegative error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-05-31ALSA: hdspm - Work around broken DDS value on PCI RME MADIAdrian Knoth
On PCI RME MADI cards, the PLL register does not contain the proper value, so the calculated system_sample_rate is wrong. In this case, we simply return the cached rate from struct hdspm. Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2012-01-11ALSA: hdspm - Provide unique driver id based on card serialAdrian Knoth
Before, /proc/asound looked like this: 2 [Default ]: HDSPM - RME RayDAT_f1cd85 RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18 In case of a second HDSPM card, its name would be Default_1. This is cumbersome, because the order of the cards isn't stable across reboots. To help userspace tools referring to the correct card, this commit provides a unique id for each card: 2 [HDSPMxf1cd85 ]: HDSPM - RME RayDAT_f1cd85 RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18 In this example, userspace (configuration files) would then use hw:HDSPMxf1cd85 to choose the right card. The serial is masked to 24bits, so this string is always shorter than sixteen chars. Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option.

2011-10-31ALSA: hdspm - Enable all firmware ranges for PCI MADI/AES cardsAdrian Knoth
From the Windows INF file, we know the firmware ranges for all RME cards. For PCIe, a single revision ID per device (RayDAT, MADI, AIO, AES) is used. Contrary, the older PCI versions use ranges, that is, one revision ID per firmware version. Instead of listing all possible revisions individually, match the range.

2011-08-15ALSA: hdspm - Enable 32 samples/period on RME RayDAT/AIOAdrian Knoth
Newer RME cards like RayDAT and AIO support 32 samples per period. This value is encoded as {1,1,1} in the HDSP_LatencyMask bits in the control register. Since {1,1,1} is also the representation for 8192 samples/period on older RME cards, we have to special case 32 samples and 32768 bytes according to the actual card.

2011-08-15ALSA: hdspm - Introduce hdspm_get_latency() to harmonize latency calculationAdrian Knoth

2011-08-15ALSA: hdspm - Reorder period sizes according to their bit representationAdrian Knoth
On newer RME cards like RayDAT and AIO, the 8192 samples per period size are no longer supported. Instead, setting all three bits of HDSP_LatencyMask to one ({1,1,1}) now corresponds to 32 samples per period. To make this more obvious to future developers, let's reorder the array according to their bit representation, starting at 64 ({0,0,0}) up to 4096 ({1,1,0}) and finally 32 ({1,1,1}).

2011-07-29ALSA: hdspm - Fix reported external sample rate on RME MADI and MADIfaceAdrian Knoth
In slave mode, the card can only detect the base frequency (32..48kHz) on the MADI link (exception: 96k frames), so the real external sample rate is this base frequency multiplied by 1, 2 or 4 depending on the speed mode. This patch enables 64..192kHz sample rates in clock slave mode, which failed before due to an alleged sample rate mismatch between the MADI link (e.g., 48kHz) and the application in DS/QS mode (e.g., 96kHz, 192kHz).

2011-02-23ALSA: hdspm - prevent reading unitialized stack memoryAdrian Knoth
Original patch by Dan Rosenberg <drosenberg@vsecurity.com> under commit e68d3b316ab7b02a074edc4f770e6a746390cb7d. I'm copying his text here: The SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl in hdspm.c allow unprivileged users to read uninitialized kernel stack memory, because several fields of the hdspm_config struct declared on the stack are not altered or zeroed before being copied back to the user. This patch takes care of it. Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
