Configuring Common Software Parameters#

The following sections describe common software configuration parameters that enable/disable or configure various features of the SiWx91x RCP Driver.

Note: The following insmod command may be used to configure multiple parameters at the same time. Note that this only applies to the parameters below that are configuring using insmod.

Replace module_param with the module parameter to be configured and <value> with the corresponding value that needs to be assigned. Module parameters in this section are grouped according to the corresponding feature.

insmod rsi_91x.ko [module_param = <value>], [module_param = <value>], ... , [module_param = <value>]

Power Save Features#

1. insmod rsi_91x.ko lp_handshake_mode = < value > Low power mode handshake type selection.

   • 0 - No handshake Mode (Default)

   • 1 - GPIO Handshake Mode

2. insmod rsi_91x.ko default_deep_sleep_enable = < value > : Enable/disable deep sleep.

   • 0 - Disable deep sleep (Default)

   • 1 - Enable deep sleep

Developer Mode Configuration Parameters#

1. insmod rsi_91x.ko power_save_opt = < value >: Module parameter to configure Power Save options.

2. insmod rsi_91x.ko standby_assoc_chain_sel = < value > : LP/HP Chain Selection in standby associated mode

   • 0 - HP Chain Enabled

   • 1 - LP Chain Enabled(Default)

3. insmod rsi_91x.ko feature_bitmap_9116 = < value > :

   • For 3.3V, set FEATURE_BITMAP_9116=0

   • For 1.8V, set FEATURE_BITMAP_9116=2

   • For 3.3V and 5 Mhz bandwidth, set FEATURE_BITMAP_9116=32 (For testing purposes only)

   Default value is 0.

4. insmod rsi_91x.ko anchor_point_gap = < value >

   Default value is 1.

5. insmod rsi_91x.ko sleep_clk_source_sel = < value >: Sleep clock source selection has the following possible values with each representing a different source.

   • 0 - Use RC clock as sleep clock

   • 1 - Use 32 KHz clock from external XTAL OSCILLATOR

   • 2 - Use 32 KHz bypass clock on UULP_GPIO_3

   • 3 - Use 32 KHz bypass clock on UULP_GPIO_4

   Default value is 0.

6. insmod rsi_91x.ko rsi_91x.ko sleep_ind_gpio_sel = < value > : sleep indication from device to host.

   • 0 - UULP_GPIO_3

   • 1 - UULP_GPIO_0

   Default value is 0.

7. insmod rsi_91x.ko host_intf_on_demand = < value > : Host Interface on Demand Feature has the following possible values.

   • 0 - Disable Host Interface on Demand Feature

   • 1 - Enable Host Interface on Demand Feature

   Default value for Host Interface on Demand Feature Options is 0, which indicates that Host Interface on Demand Feature is disabled.

8. insmod rsi_91x.ko ext_opt = < value > : Extended Options

Default value for Extended options is 0.

1. insmod rsi_91x.ko pta_config = < value > : PTA 3-Wire Co-Existence has following options.

   • 0 - PTA_CONFIG_DISABLED(default)

   • 1 - PTA_CONFIG_1 Aggressive Grant

   • 2 - PTA_CONFIG_2 Protect Response Tx

   • 3 - PTA_CONFIG_3 Protect both Tx and Response Tx

   Default value is 0.

Miscellaneous Features#

1. insmod rsi_91x.ko driver_mode_value = < value >: Enable sniffer mode support. Default value is 1.

   • 1 - End to end mode

   • 7 - Sniffer mode

2. insmod rsi_sdio.ko sdio_clock = < value >: Set the SDIO clock while while installing the driver (only for SDIO interface). The range is 1- 50 MHz. Default value is 50 MHz.

   Note: This parameter can only be used with the rsi_sdio.ko kernel module.

3. insmod rsi_91x.ko ulp_gpio_read = < value >: In GPIO handshake, this param configures Host GPIO read pin. It will vary from platform to platform. Default value is 0xFF.

4. insmod rsi_91x.ko ulp_gpio_write = < value >: In GPIO handshake, this param configures Host GPIO write pin. It will vary from platform to platform. Default value is 0xFF.
