Enumeration Type Documentation

enum HPI_ADAPTER_PROPERTIES

Adapter properties These are used in HPI_AdapterSetProperty() and HPI_AdapterGetProperty()

Enumerator:

HPI_ADAPTER_PROPERTY_GROUPING	Adapter grouping property Indicates whether the adapter supports the grouping API (for ASIO and SSX2)
HPI_ADAPTER_PROPERTY_ENABLE_SSX2	Driver SSX2 property Tells the kernel driver to turn on SSX2 stream mapping. This feature is not used by the DSP. In fact the call is completely processed by the driver and is not passed on to the DSP at all.
HPI_ADAPTER_PROPERTY_SSX2_SETTING	Adapter SSX2 property Indicates the state of the adapter's SSX2 setting. This setting is stored in non-volatile memory on the adapter. A typical call sequence would be to use HPI_ADAPTER_PROPERTY_SSX2_SETTING to set SSX2 on the adapter and then to reload the driver. The driver would query HPI_ADAPTER_PROPERTY_SSX2_SETTING during startup and if SSX2 is set, it would then call HPI_ADAPTER_PROPERTY_ENABLE_SSX2 to enable SSX2 stream mapping within the kernel level of the driver.
HPI_ADAPTER_PROPERTY_IRQ_RATE	Enables/disables PCI(e) IRQ. A setting of 0 indicates that no interrupts are being generated. A DSP boot this property is set to 0. Setting to a non-zero value specifies the number of frames of audio that should be processed between interrupts. This property should be set to multiple of the mixer interval as read back from the HPI_ADAPTER_PROPERTY_INTERVAL property.
HPI_ADAPTER_PROPERTY_READONLYBASE	Base number for readonly properties.
HPI_ADAPTER_PROPERTY_LATENCY	Readonly adapter latency property. This property returns in the input and output latency in samples. Property 1 is the estimated input latency in samples, while Property 2 is that output latency in samples.
HPI_ADAPTER_PROPERTY_GRANULARITY	Readonly adapter granularity property. The granulariy is the smallest size chunk of stereo samples that is processed by the adapter. This property returns the record granularity in samples in Property 1. Property 2 returns the play granularity.
HPI_ADAPTER_PROPERTY_CURCHANNELS	Readonly adapter number of current channels property. Property 1 is the number of record channels per record device. Property 2 is the number of play channels per playback device.
HPI_ADAPTER_PROPERTY_SOFTWARE_VERSION	Readonly adapter software version. The SOFTWARE_VERSION property returns the version of the software running on the adapter as Major.Minor.Release. Property 1 contains Major in bits 15..8 and Minor in bits 7..0. Property 2 contains Release in bits 7..0.
HPI_ADAPTER_PROPERTY_MAC_ADDRESS_MSB	Readonly adapter MAC address MSBs. The MAC_ADDRESS_MSB property returns the most significant 32 bits of the MAC address. Property 1 contains bits 47..32 of the MAC address. Property 2 contains bits 31..16 of the MAC address.
HPI_ADAPTER_PROPERTY_MAC_ADDRESS_LSB	Readonly adapter MAC address LSBs The MAC_ADDRESS_LSB property returns the least significant 16 bits of the MAC address. Property 1 contains bits 15..0 of the MAC address.
HPI_ADAPTER_PROPERTY_EXTENDED_ADAPTER_TYPE	Readonly extended adapter type number The EXTENDED_ADAPTER_TYPE property returns the 4 digits of an extended adapter type, i.e ASI8920-0022, 0022 is the extended type. The digits are returned as ASCII characters rather than the hex digits that are returned for the main type Property 1 returns the 1st two (left most) digits, i.e "00" in the example above, the upper byte being the left most digit. Property 2 returns the 2nd two digits, i.e "22" in the example above
HPI_ADAPTER_PROPERTY_LOGTABLEN	Readonly debug log buffer information.
HPI_ADAPTER_PROPERTY_IP_ADDRESS	Readonly adapter IP address For 192.168.1.101 Property 1 returns the 1st two (left most) digits, i.e 192*256 + 168 in the example above, the upper byte being the left most digit. Property 2 returns the 2nd two digits, i.e 1*256 + 101 in the example above,
HPI_ADAPTER_PROPERTY_BUFFER_UPDATE_COUNT	Readonly adapter buffer processed count. Returns a buffer processed count that is incremented every time all buffers for all streams are updated. This is useful for checking completion of all stream operations across the adapter when using grouped streams.
HPI_ADAPTER_PROPERTY_INTERVAL	Readonly mixer and stream intervals. These intervals are measured in mixer frames. To convert to time, divide by the adapter samplerate. The mixer interval is the number of frames processed in one mixer iteration. The stream update interval is the interval at which streams check for and process data, and BBM host buffer counters are updated. Property 1 is the mixer interval in mixer frames. Property 2 is the stream update interval in mixer frames.
HPI_ADAPTER_PROPERTY_CAPS1	Adapter capabilities 1 Property 1 - adapter can do multichannel (SSX1) Property 2 - adapter can do stream grouping (supports SSX2)

	)

Sets the operating mode of an adapter.

The adapter must be restarted for the mode to take effect. Under Windows this means that the computer must be rebooted.

	)

Adapter set mode extended.

This updated version of HPI_AdapterSetMode() allows querying supported modes.
When wQueryOrSet=HPI_ADAPTER_MODE_QUERY doesn't set the mode, but the return value reflects whether the mode is valid for the adapter.
When wQueryOrSet=HPI_ADAPTER_MODE_SET, the mode of the adapter is changed if valid.
