Subject: Kernel 5.9-rc regression.
Date: Fri, 2 Oct 2020 04:15:43 +0800 [thread overview]
Message-ID: <25b6a64b-b5ac-c85a-abde-909fb2d768f9@wanyeetech.com> (raw)
Hi Thomas and list,
There is a strange phenomenon in kernel 5.9-rc: when using kernel 5.9-rc
with debian 10 and running htop, the memory footprint will be displayed
as 3.99T. When the actual memory footprint increases, the displayed
value will be reduced to 3.98T, 3.97T etc. These phenomena have been
confirmed in X1000, X1830, and JZ4780 (disable SMP), this phenomenon
does not seem to affect the SMP processor. When the JZ4780 turn on SMP,
the memory footprint will be displayed normally.
The following is the relevant log:
