The audio driver ( sound/soc/sprd/ ) is based on ASoC but with custom machine drivers.
A known hurdle in custom UMS9117 driver development is the lack of an official, comprehensive NAND flash controller driver. Standard drivers frequently get stuck simply trying to read the chip ID.
: System clutter can slow down driver execution. Clearing the cache helps the operating system run lean.
Here is a deep, technical review of the UMS9117 driver landscape. unisoc ums9117 driver better
Target the x64 folder structure and choose the SCI Android USB Serial driver profile.
: It prevents the "Device Not Recognized" errors common during firmware updates.
Unisoc has several variants of this architecture tailored for different price points: Go to product viewer dialog for this item. Common in newer ultra-budget 4G feature phones. UMS9117 (T117) The audio driver ( sound/soc/sprd/ ) is based

Here is the step-by-step guide to getting the driver setup.
Clearly, "better" drivers yield tangible improvements. : System clutter can slow down driver execution
"Management wants to scrap the project," Chen sighed. "They say it’s a 'budget chip' and doesn't deserve a custom stack. Just patch it and ship it."
The Mali GPU driver is a prime candidate for improvement. You can manually inject newer .so (shared object) files:
