Hi,
I'm attempting to run PARSEC benchmarks in FS mode on gem5-v21.0. I have
encountered an issue with KVM on Intel machine. I believe the same was
addressed by this patch
<https://gem5-review.googlesource.com/c/public/gem5/+/7361> recommended
earlier in the mailing list
<https://gem5-users.gem5.narkive.com/8DBihuUx/running-fs-py-with-x86kvmcpu-failed>
.
panic: KVM: Failed to enter virtualized mode (hw reason: 0x80000021)
Most of the tutorials on gem5art
<http://www.gem5.org/documentation/gem5art/tutorials/boot-tutorial> in gem5
documentation recommend using gem5-v20.1, but I noticed that applying the
patch on 20.1 or 21 is not a trivial merge. For the time being, I've been
able to use this specific commit tag described in gem5art-experiments
<https://github.com/darchr/gem5art-experiments>.
git clone https://gem5.googlesource.com/public/gem5cd gem5
git checkout *d40f0bc579fb8b10da7181*
git remote add darchr https://github.com/darchr/gem5
git fetch darchr*git cherry-pick
6450aaa7ca9e3040fb9eecf69c51a01884ac370c**git cherry-pick
3403665994b55f664f4edfc9074650aaa7ddcd2c*
scons build/X86/gem5.opt -j8
At this point, I have two questions:
1. Is the KVM patch necessary on gem5-v21?
2. In case someone has encountered a similar issue previously, were you
able to find a way to merge the patch on newer gem5 releases
Thank you for your time.
Regards,
Rajesh Shashi Kumar
