[Qemu-devel] [Bug 942299] [NEW] Regression in booting HelenOS/ppc under Qemu

[Jakub Jermar]

Public bug reported:

Mark Cave-Ayland identified Qemu commit
41557447d30eeb944e42069513df13585f5e6c7f as the first bad commit which
prevents HelenOS/ppc from booting with OpenBIOS taken from Qemu 0.11.1.
Note that we deliberately use the OpenBIOS from  Qemu 0.11.1 because
there is another suspected, unrelated bug in newer versions of OpenBIOS.

For reproducing purposes, the following HelenOS image can be used
(latest HelenOS exhibits the same behavior):

http://www.helenos.org/releases/HelenOS-0.4.2-ppc32.iso

Commit 41557447d30eeb944e42069513df13585f5e6c7f will result in HelenOS
not making any further progress after it prints "init: Spawning
/srv/devfs".

The previous commit, f844c817d726cd2bdb431aa41c8217891ede2eaf, works
fine - HelenOS will spawn a couple of shell instances and will be
accepting user input.

Just for the reference,

commit 41557447d30eeb944e42069513df13585f5e6c7f
Author: Alexander Graf <agraf@suse.de>

    PPC: Redesign interrupt trigger path

    According to the Book3S spec, the interrupt context starts with an MSR
    value that is rather simple. If we leave out the HV case, it's almost
    always 0.

    To reflect this, let's redesign the way that MSR value gets calculated.
    Using this, we also squash the bug where MSR_POW can slip through into
    the interrupt handler MSR.
