Qualcomm upstreamed new Cloud AI 100 "AIC100" firmware today to linux-firmware.git to fix a rather significant power/performance issue for these AI accelerators.
It turns out that the Qualcomm Cloud AI accelerators had a rather egreious firmware issue causing excessive power use for some workloads that in turn led to thermal throttling and lower performance.
[1]This commit today to linux-firmware.git for updating the Qualcomm AIC100 firmware notes:
"Update the firmware files for the Qualcomm aic100 product to that of the 1.20.2.6 release. This release contains a bug fix that addresses an issue with the device consuming excessive power under some workloads which then causes the device to [excessively] throttle and reduce overall performance."
No further details were publicly shared, but if you are using any Qualcomm Cloud AI hardware, you may want to ensure that your firmware is updated.
