Subject: [Qemu-devel] [BUG] QEMU crash during cpu reset (MIPS regression)
Date: Fri, 04 May 2007 22:12:10 +0200 [thread overview]
Message-ID: <463B939A.1090508@mail.berlios.de> (raw)
Resetting a MIPS cpu currently does not work, because important
entries in env (CPUMIPSState) are filled with 0 at the
beginning of function cpu_reset.
At system start, these values are set in cpu_mips_register.
After reset, env->nb_tlb == 0 results in a division by zero
crash of QEMU.
We can either re-arrange the entries in CPUMIPSState
(move those which must not be zero'ed to the end), or
cpu_reset must call cpu_mips_register.
Which solution is better?
Stefan
