Subject: [Stable-7.2.6 02/37] hw/smbios: Fix smbios_smp_sockets caculation
Date: Sat,  9 Sep 2023 16:04:32 +0300	[thread overview]
Message-ID: <20230909130511.354171-2-mjt@tls.msk.ru> (raw)
In-Reply-To: <qemu-stable-7.2.6-20230909160328@cover.tls.msk.ru>

From: Zhao Liu <zhao1.liu@intel.com>

smp.sockets is the number of sockets which is configured by "-smp" (
otherwise, the default is 1). Trying to recalculate it here with another
rules leads to errors, such as:

1. 003f230e37d7 ("machine: Tweak the order of topology members in struct
   CpuTopology") changes the meaning of smp.cores but doesn't fix
   original smp.cores uses.

   With the introduction of cluster, now smp.cores means the number of
   cores in one cluster. So smp.cores * smp.threads just means the
   threads in a cluster not in a socket.

2. On the other hand, we shouldn't use smp.cpus here because it
   indicates the initial number of online CPUs at the boot time, and is
   not mathematically related to smp.sockets.

So stop reinventing the another wheel and use the topo values that
has been calculated.
