Daniel P. Berrangé 8b1dac1ad5 hw/char/sclpconsole-lm: skip automatic zero-init of large array ... The 'process_mdb' method has a 4k byte array used for copying data between the guest and the chardev backend. Skip the automatic zero-init of this array to eliminate the performance overhead in the I/O hot path. The 'buffer' array will be selectively initialized when data is converted between EBCDIC and ASCII. Signed-off-by: Daniel P.
