Subject: [PATCH V7 0/2] firmware: Add support for boot_stats
Date: Wed, 5 Jul 2023 11:02:30 +0530 [thread overview]
Message-ID: <cover.1688533340.git.quic_schowdhu@quicinc.com> (raw)
Qualcomm's proprietary Android boot-loaders capture boot time
stats, like the time when the bootloader started execution and at what
point the bootloader handed over control to the kernel etc. in the IMEM
region. This information is captured by the bootloader and populated on
the device tree properties "pre-abl-time" and "abl-time" which can be
be viewed from the user space like as follows:-
/sys/firmware/devicetree/base/bootstats # cat abl_time
17898
As a part of this patch series added the bindings for boot-stats which
was suggested in the v6 of the series. The link for the same is as
follows:-
