It seems like you're discussing a technical update related to the QCA9377 firmware, specifically addressing Qualcomm's RED compliance and the need for additional IRAM banks. Here's a breakdown of the information you provided:

Impact:

The new firmware for QCA9377 is designed to comply with Qualcomm's RED (Radio Equipment Directive) standards.
The updated firmware requires more IRAM (Instruction RAM) banks than the original 4 banks provided by the current BDF (Binary Data Format) and firmware.
Fix:

To address the issue, the proposed fix is to change the number of IRAM banks from 4 to 9.
Regression Potential:

The regression potential is described as low. Increasing the number of IRAM banks is not expected to cause harm.
Miscellaneous Information:

Both the driver patch and the new firmware are not yet upstream.
To avoid using dkms package (Dynamic Kernel Module Support), it's suggested to make the change to the IRAM bank number before the patch is ready.
In summary, the proposed fix involves a relatively low-risk change—increasing the number of IRAM banks from 4 to 9—to accommodate the requirements of the new firmware for QCA9377, ensuring compliance with Qualcomm's RED standards. The change is suggested to be implemented before the driver patch and new firmware are upstreamed, and it aims to avoid the use of dkms packages. Answer Source https://www.treasuryprime.com/
