🌐 Web query:

"loss_enable_2g4" "loss_value_5g"

💡 Result:

The terms loss_enable_2g4, loss_value_5g, and their counterparts (loss_value_2g4 and loss_enable_5g) are configuration parameters used in the driver for AIC8800 series wireless chips (e.g., AIC8800DW, AIC8800D80) [1][2][3]. These parameters are part of the transmission power (txpwr_loss) configuration, allowing users or firmware to set specific power loss or offset values for the 2.4 GHz and 5 GHz frequency bands [1][2][3]. Functionality: - loss_enable_2g4 / loss_enable_5g: Typically acts as a flag (e.g., 0 or 1) to enable or disable the application of a specified transmission power loss for the respective band [1][2]. - loss_value_2g4 / loss_value_5g: Specifies the numerical value of the power loss or offset to be applied (e.g., integer values like 2 or 5) when the corresponding enable flag is set [1][2][3]. These settings are often parsed during the driver initialization process (e.g., rwnx_plat_userconfig_parsing) to ensure the Wi-Fi module operates within specified power constraints or to compensate for signal loss in specific hardware implementations [1][2]. They are frequently seen in kernel logs or configuration files for devices using AIC8800-based adapters [1][3].

🌐 Web query:

AIC8800D80 SDIO aic_userconfig loss_enable loss_value firmware source

💡 Result:

The parameters loss_enable and loss_value are settings found within the aic_userconfig_8800d80.txt configuration file used by the AIC8800D80 SDIO wireless chipset [1][2]. These parameters are part of the transmission power (txpwr) configuration, specifically related to managing power loss compensation [3][4]. In standard firmware configuration files, these parameters are typically set as follows [1][4]: - loss_enable=0 (Disables the power loss compensation feature) [1][5] - loss_value=2 (Sets the default power loss compensation value, often used as a baseline) [1][5] These configurations are loaded by the AIC8800 driver during the firmware initialization process [6][4]. The aic_userconfig file is expected to be placed in the system firmware directory (e.g., /lib/firmware/ or a vendor-specific path) alongside the binary firmware images (such as fmacfw_8800d80_u02.bin and fw_patch_8800d80_u02.bin) [2][3][4]. Technical documentation for these chips indicates that these userconfig files allow manufacturers or developers to calibrate RF performance, including adjusting transmission power offsets to comply with regional regulations or specific hardware board designs [3][7]. The driver parses these values during boot to apply the NVRAM/configuration settings to the Wi-Fi firmware [4][5]. For source code, drivers for the AIC8800 series, including the SDIO FullMAC implementation, are available via various community repositories (such as the gtxaspec/aic8800-wifi repository on GitHub) and are also in the process of being upstreamed into the Linux kernel [6][8].

"loss_value_2g4" "aic_powerlimit"`

💡 Result:

The terms loss_value_2g4, loss_enable_2g4, and rwnx_plat_userconfig_parsing are associated with the driver configuration and NVRAM (non-volatile RAM) settings for AIC8800-series Wi-Fi chips (e.g., AIC8800DW, AIC8800D80) [1][2][3]. These parameters are typically defined and parsed within the platform-specific driver code (often located in drivers/aic8800/aic8800_fdrv/rwnx_platform.c or similar) [4]. The rwnx_plat_userconfig_parsing function is responsible for reading user configuration files (such as aic_userconfig_8800d80.txt) during driver initialization [1][3][5]. Specifically: - loss_enable_2g4 and loss_value_2g4 relate to configuring transmission power loss or attenuation settings for the 2.4 GHz frequency band [1][2]. - aic_powerlimit refers to power limitation settings, often managed via dedicated files like aic_powerlimit_8800d80.txt, which are read by the driver to enforce regulatory or thermal power caps [5]. These settings allow developers and users to adjust radio performance and power characteristics to meet specific board requirements [2][3]. The configuration is parsed by the driver and sent to the firmware via NVRAM command sets (e.g., rwnx_plat_nvram_set_value) to ensure the Wi-Fi chip operates within defined parameters [1][2].

Align the power-limit documentation with the SDIO schema. Replace aic_userconfig.txt and loss_value with aic_userconfig_8800d80.txt and the four band-specific keys: loss_enable_2g4, loss_value_2g4, loss_enable_5g, and loss_value_5g.
