Subject: [Qemu-devel] [PATCH RFC 0/2] numa: allocate CPUs masks dynamically
Date: Wed, 16 Nov 2016 17:02:54 +0100 [thread overview]
Message-ID: <1479312176-224580-1-git-send-email-imammedo@redhat.com> (raw)
This series removes global MAX_CPUMASK_BITS constant
so that it won't inderectly influence maximum CPUs count
supported by different targets.
It replaces statically allocated bitmasks with dynamically
allocated ones using '-smp maxcpus' value for setting
bitmasks size.
That would allocate just enough memory to handle all
CPUs indexes that a QEMU instance would ever have.
