Before, /proc/asound looked like this:
2 [Default ]: HDSPM - RME RayDAT_f1cd85
RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18In 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 18In 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

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. For this version
it'll simply give a warning, but it'll break next kernel version.Signed-off-by: Rusty Russell

Commit c09403dcc5698abf214329fbbf3cf8dbb5558bea has introduced a
regression: PCIe versions of RME MADI were no longer detected, because
the MADIface ID (0xd5) was used instead of the correct 0xd2.This commit fixes the problem.

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.
This commit enables all MADI and AES PCI versions ever shipped.

Signed-off-by: Takashi Iwai -
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.Signed-off-by: Adrian Knoth

Currently, hdspm_decode_latency is called several times, violating the
DRY principle. Given that we need to distinguish between old and new
cards when decoding the latency bits in the control register, introduce
hdspm_get_latency() to provide the required functionality.Signed-off-by: Adrian Knoth
Signed-off-by: Takashi Iwai -
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}).Note that this patch doesn't change semantics.

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).Signed-off-by: Adrian Knoth

When running in slave mode (no clock master), there is no way to

The name argument of request_irq() appears in /proc/interrupts, and

The convention for pci_driver.name entry in kernel drivers seem to be
the module name or equivalent ones. But, so far, almost all PCI sound
drivers use more verbose name like "ABC Xyz (12)", and these are fairly

use KBUILD_MODNAME for more unified appearance.Signed-off-by: Takashi Iwai
