I submitted two patches for the Bluetooth subsystem recently and wanted to = kindly follow up to see if you had a chance to review them: - https://patchwork.kernel.org/project/bluetooth/patch/20250606090559.89624= 2-2-hildawu@realtek.com/ - https://patchwork.kernel.org/project/bluetooth/patch/20250606090559.89624= 2-3-hildawu@realtek.com/ These patches address the future chips firmware format enhancement and down= load firmware improve. Please let me know if you need any further info or changes from my side. Thank you very much for your time and consideration.

Patch Overview: 1. Bluetooth: btrtl: Firmware format v3 support - This addition ensures the latest RTK chipsets with firmware version 3 are fully supported. It includes necessary modifications to accommodate new firmware structure changes. 2. Bluetooth: btrtl: Add enhanced download support - By leveraging ACL links for firmware transmission, the download process is significantly accelerated, reducing the overall time and enhancing performance. Testing and Validation: - The implementation has been tested on various RTK chipsets under Linux based distribution. Impact and Benefits: These enhancements are beneficial for future firmware v3 chips and compatib= le with previous firmware versions. Users can expect shortened initializati= on times. Your feedback and suggestions are welcome to further refine these changes. Thank you for considering these enhancements. Best regards, Hilda --- Change in V2: - Move structure to btrtl.h - Fill in the missing symbols - Fix build warnings Hilda Wu (2): Bluetooth: btrtl: Firmware format v3 support Bluetooth: btrtl: Add enhanced download support drivers/bluetooth/btrtl.c | 857 +++++++++++++++++++++++++++++++++++++- drivers/bluetooth/btrtl.h | 122 ++++++ drivers/bluetooth/btusb.c | 3 + 3 files changed, 974 insertions(+), 8 deletions(-) -- 2.34.1
